DETAILED DESCRIPTION OF THE DRAWINGS

(9) Embodiments of the diecasting tool system according to the invention shown specifically in FIGS. 1 to 8 and other embodiments thereof will be discussed in more detail hereunder by means of FIGS. 1 to 8. The diecasting tool system is intended and specified for use in a diecasting machine 13 which is schematically indicated in FIG. 1 and serves for casting cast parts by means of diecasting technology. The diecasting machine 13 can in particular be a metal diecasting machine, for example of the cold-chamber or hot-chamber type, for diecasting cast parts from aluminium, magnesium, zinc or another commonplace metal casting material, or alternatively be a plastic injection-moulding machine for producing cast parts from plastics material by means of injection-moulding technology. The diecasting machine 13 herein can be of any machine type or machine construction, respectively, known per se and be of a machine size which is known per se, wherein only the particularities of the diecasting tool system which are specific to the invention have to be discussed here, while reference in terms of other details of the diecasting machine 13 can furthermore be made to the technical knowledge and the prior art. Depending on the embodiment of the system herein, the diecasting tool system according to the invention when required can also be selectively used for different types and/or machine sizes of the diecasting machine 13. As is commonplace, the diecasting machine 13 includes a movable mould half 9 and an immovable mould half 10, the diecasting tool system being disposed thereon or therebetween, respectively, as can be seen from FIG. 2.

(10) As is visualized in the manner of a block diagram in FIG. 1, the diecasting tool system shown therein includes a base plate 1 which is embodied in a machine-related manner, that is to say that the base plate 1 is specified for use or assembly, respectively, on the diecasting machine 13 for which the diecasting tool system is specified. The diecasting tool system furthermore includes at least one first set 3.sub.1 of a plurality 3.sub.11 to 3.sub.1p of contour-imparting mould components 3, p being an arbitrary natural of more than one, and a plurality 2.sub.1 to 2.sub.n of not contour-imparting tool receptacle module components 2, n being an arbitrary natural of more than one. The number p and the shape of the contour-imparting mould components 3.sub.11 to 3.sub.1p that form the respective set 3.sub.1 vary depending on the cast part to be cast. The contour-imparting mould component or components 3 conjointly herein form a mould insert 3 which is presently accordingly identified by the same reference sign, or in their entirety correspond to the mould insert conventionally understood by the person skilled in the art.

(11) The base plate 1, the contour-imparting mould components, or the mould insert 3 formed by the latter, respectively, and the not contour-imparting tool receptacle module components 2 are specified for releasably assembling the respective set 3.sub.1 of contour-imparting mould components 3 and an assigned set W.sub.1 of tool receptacle module components which are selected from the entirety 2.sub.1 to 2.sub.n of the not contour-imparting tool receptacle module components 2 on the base plate 1, more specifically on a fastening side 1a of the base plate 1 (opposite a non-fastening rear side 1b) which serves this purpose, as can be seen from each of FIGS. 2 to 8, for example, so as to cast a corresponding cast part using the diecasting tool system. To this end, the respective set 3.sub.1 of contour-imparting mould components 3.sub.11 to 3.sub.1p in an assembled position on the base plate 1 forms a casting contour 12 for the cast part to be cast. A special embodiment of the casting contour 12 is schematically shown in an exemplary manner in FIGS. 2 to 5.

(12) It is understood that the base plate 1 as well as a set of contour-imparting mould components 3 assembled on said base plate 1 or on the fastening side 1a thereof, respectively, and an associated set of the not contour-imparting tool receptacle module components 2 assembled on said base plate 1 or on the fastening side 1a thereof, respectively, in the diecasting tool system are in each case typically present once for each of the two mould halves 9, 10 of the diecasting machine 13, as can be seen from the cross-sectional view in the exemplary embodiment of FIG. 2. An ejector mechanism 11 which is schematically indicated in FIG. 2, for example, and is known per se to the person skilled in the art is typically assigned to the base plate 1 which is situated proximal to the movable mould half 9 herein, this therefore not requiring any more detailed explanations.

(13) The base plate 1 on the fastening side 1a thereof includes a fastening grid of a plurality of fastening points 14, in particular fastening bores, as can be seen from FIGS. 3 to 6, which are disposed so as to be distributed in a regular or irregular pattern across a fastening region Bb, wherein the fastening points 14 for the sake of simplicity are not plotted in the views of FIGS. 3 and 4. In the example shown, the fastening region Bb extends substantially across the entire extent of the fastening side 1a; alternatively, said fastening region Bb extends only across a sub-region of said fastening side 1a, for example only across a central region of the area of the fastening side 1a, having in terms of area an extent of, for example, at most 50 to 80% of the area of the fastening side 1a. The fastening bores 14 can receive fastening bolts or other fastening means which are conventionally used for fastening purposes in diecasting tools.

(14) In corresponding embodiments of the diecasting tool system according to the invention, the contour-imparting mould components 3.sub.11 to 3.sub.1p of the single, first set 3.sub.1 of contour-imparting mould components 3, or at least of the first set 3.sub.1 of a plurality of sets 3.sub.1, 3.sub.2, 3.sub.3 of contour-imparting mould components 3, respectively, and the assigned set W.sub.1 of the not contour-imparting tool receptacle module components 2 are able to be assembled in at least two different orientations and/or in at least two displaced positions on the base plate 1. To this end, FIGS. 2 and 3 visualize a first variant of assembly, and FIGS. 4 and 5 a second variant of assembly in which a first orientation P.sub.1, as can be seen in particular from FIG. 3, differs from a second orientation P.sub.2, as can be seen from FIGS. 4 and 5. The term orientation herein means the spatial position and in particular the rotary position of the contour-imparting mould components 3 and of the assigned set W.sub.1 of the not contour-imparting tool receptacle module components 2 relative to the base plate 1.

(15) Said different orientations P.sub.1, P.sub.2, or positionings, respectively, herein are to be understood such that at least one of the components to be assembled on the base plate 1, that is to say at least one of the contour-imparting mould components 3 and of the not contour-imparting tool receptacle module components 2, can be disposed in a correspondingly different orientation or displaced positioning, respectively, on the base plate 1, wherein all other components, depending on the requirement and the specific application, can in each case likewise be assembled so as to be differently oriented or positioned, respectively, or in the same orientation or position, respectively, on the base plate 1. The different orientation or position, respectively, at least for the contour-imparting mould components 3 is typically implemented so as to form the casting contour 12 formed by the latter in a correspondingly different orientation or position, respectively, on the base plate 1. In many instances, one or a plurality of the not contour-imparting tool receptacle module components 2 are moreover able to be assembled in a different orientation or position, respectively, on the base plate 1.

(16) The contour-imparting mould components 3 are individually adapted to the cast part to be cast, while the not contour-imparting tool receptacle module components 2 do not participate in determining the casting contour 12 for the cast part to be cast and therefore, depending on the embodiment of the system, can be resorted to in a variable and flexible manner for assembling a complete tool construction for the respective cast part. The tool receptacle module components for forming the respective set W.sub.1 used for casting the respective cast part herein are suitably selected from the entirety 2.sub.1 to 2.sub.n of all not contour-imparting tool receptacle module components 2. The not contour-imparting tool receptacle module components 2 can inter alia serve for supporting the secure mounting of the contour-imparting mould components 3 on the base plate, for example by way of suitable form-fitting and/or force-fitting connections between the not contour-imparting tool receptacle module components, on the one hand, and the contour-imparting mould components 3, on the other hand, such that the required strength and dimensional stability of the tool components assembled in a modular manner on the base plate, including the contour-imparting mould components 3, in relation to the compressive stresses arising during the casting procedure is ensured.

(17) As has already been mentioned, in corresponding embodiments of the invention a plurality of sets 3.sub.1, . . . of contour-imparting mould components 3.sub.11 to 3.sub.1p, . . . for selectively assembling on the base plate 1 are present conjointly with in each case one assigned set W.sub.1, W.sub.2, W.sub.3 of tool receptacle module components selected from the entirety 2.sub.1 to 2.sub.n of the not contour-imparting tool receptacle module components 2, such that a corresponding plurality of different cast parts can be cast by the diecasting tool system while using the same base plate 1. To this end, an embodiment of the system which, in addition to the first set 3.sub.1 of contour-imparting mould components 3.sub.11 to 3.sub.1p, includes two further sets 3.sub.2, 3.sub.3 of contour-imparting mould components 3.sub.21 to 3.sub.2q, or 3.sub.31 to 3.sub.3r, q and r being arbitrary naturals of more than one, for selectively assembling on the base plate 1 conjointly with in each case one assigned set W.sub.1, W.sub.2, W.sub.3 of the tool receptacle module components 2 for casting a first cast part G1, a second cast part G2, or a third cast part G3, respectively, is shown in FIG. 1. In other embodiments, the diecasting tool system comprises only one or two sets, for example the sets 3.sub.1 and 3.sub.2, or more than three sets, of contour-imparting mould components 3 and in each case a corresponding number of assigned sets W.sub.1, . . . of the tool receptacle module components 2.

(18) In advantageous embodiments, the fastening grid is formed by a two-dimensional field of the fastening points 14, as in the shown example of FIG. 6, in which the fastening points 14 are disposed so as to be mutually spaced apart in a plurality of rows 14.sub.Z1, 14.sub.Z2, . . . , 14.sub.Zn which run in parallel in a row direction Rz, wherein the rows 14.sub.Z1, 14.sub.Z2, . . . , 14.sub.Zn are mutually spaced apart in a row spacing direction Rs which is not parallel to the row direction Rz. As can be seen from FIGS. 5 and 6, the row direction Rz and the row spacing direction Rs in the example shown are in particular mutually perpendicular, that is to say that the fastening points 14 are disposed in rows and columns, so to speak. In the example shown, the fastening points 14 of in each case two neighbouring rows are disposed so as to be centrically offset, that is to say so as to be offset by approximately half the spacing thereof in the row direction Rz. In alternative embodiments, the row direction Rz and the row spacing direction Rs run so as to be mutually oblique, and/or the fastening points 14 of in each case two neighbouring rows are disposed so as not to be offset or in any case not centrically offset. Optionally, additional fastening points 14, such as fastening points 14a which are shown in an exemplary manner in FIG. 6, can be provided in addition to the rows mentioned, or outside the latter, respectively, depending on the requirement. Likewise, some of the fastening points 14 shown in FIG. 6 can optionally be absent in one or a plurality of the rows, that is to say that not all the fastening points 14 have to be mandatorily disposed at a mutual identical space within a respective row.

(19) The assembling of the various components on the base plate 1 can take place while using screw connections, for example, to which end the base plate 1 in corresponding implementations is provided with a regular or irregular pattern of fastening bores which can receive threaded bolts or similar fastening bolts by way of which the respective tool component is releasably fastened to the base plate 1 in the desired position or orientation, respectively.

(20) In corresponding embodiments of the diecasting tool system according to the invention, at least two sets 3.sub.1, 3.sub.2 of contour-imparting mould components 3 and accordingly at least two assigned sets W.sub.1, W.sub.2, . . . of the entirety 2.sub.1 to 2.sub.n of the not contour-imparting tool receptacle module components 2 are present in such a manner that at least one of the not contour-imparting tool receptacle module components 2 is associated with at least two of the sets W.sub.1, W.sub.2, . . . of the not contour-imparting tool receptacle module components 2.sub.1 to 2.sub.n. FIG. 1 thus in an exemplary manner visualizes a case in which a not contour-imparting tool receptacle module component 2.sub.f in the form of the module component 2.sub.1 is associated with the set W.sub.1 used for casting the first cast part G1 and with the set W.sub.2 of the not contour-imparting tool receptacle module components 2 used for casting the second cast part G2. In a similar manner, the module component 2.sub.n-1 is associated with the first and the third set W.sub.1, W.sub.3 of the not contour-imparting tool receptacle module components 2 for casting the first and third cast part G1, G3, respectively, and the module components 2.sub.3 and 2.sub.n-2 are in each case associated with all three sets W.sub.1, W.sub.2, W.sub.3 of the not contour-imparting tool receptacle module components 2 for casting the first, second and third cast part G1, G2, G3, respectively.

(21) In corresponding embodiments, at least one not contour-imparting tool receptacle module component is not associated with at least one of the sets W.sub.1, W.sub.2, W.sub.3 of the tool receptacle module components 2 for casting a respective associated cast part. In FIG. 1, a module component 2.sub.g in the form of the module component 22 is thus not associated with the set W.sub.1 of the not contour-imparting tool receptacle module components 2 used for casting the first cast part G1, and is also not associated with the third set W.sub.3 but is only associated with the second set W.sub.2. In the exemplary embodiment of FIG. 1, the module component 2.sub.1 in an analogous manner is associated only with the first and the second set W.sub.1, W.sub.2 and not with the third set W.sub.3, the module component 2.sub.n-1 is associated only with the first and the third set W.sub.1, W.sub.3 and not with the second set W.sub.2, and the module component 2.sub.n is associated only with the third set W.sub.3 but not with the first and the second set W.sub.1, W.sub.2 of the tool receptacle module components 2.

(22) In corresponding embodiments, the entirety 2.sub.1 to 2.sub.n of not contour-imparting tool receptacle module components 2 comprises at least one slider component 4 and/or at least one guide component 5 and/or at least one ventilation component 6 and/or at least one centring plate 7. Implementations in which a plurality of slider components 4, a plurality of guide components 5, a ventilation component 6 and a plurality of centring plates 7 are used as not contour-imparting tool receptacle module components are illustrated in an exemplary manner in FIGS. 2 to 5.

(23) In corresponding embodiments herein, at least one centring plate 7 and a plurality of the contour-imparting mould components 3 which are associated with the respective cast part are in each case assembled on each of the two base plates 1 for the movable mould half 9 and the fixed mould half 10, as can be seen in the example of FIG. 2. Often, one or a plurality of the slider components 4 and likewise one or a plurality of the guide components 5 are in each case assembled on each of the two base plates 1.

(24) In advantageous implementations of the diecasting tool system, the entirety 2.sub.1 to 2.sub.n of not contour-imparting tool receptacle module components 2 comprises a first, machine type-specific group MG1 of one or a plurality of the not contour-imparting tool receptacle module components 2, and a second machine type-spanning group MG2 of one or a plurality of the not contour-imparting tool receptacle module components 2. FIG. 1 visualizes an example having in each case a plurality of the not contour-imparting tool receptacle module components 2 in each of the two groups MG1, MG2. Those not contour-imparting tool receptacle module components which are specially conceived for use in a specific machine type or a specific machine size, respectively, of the diecasting machine 13 are associated with the machine type-specific group MG1. Those not contour-imparting tool receptacle module components which can be used in two or more different machine types or machine sizes of the diecasting machine 13 are associated with the machine type-spanning group MG2, to which end said tool receptacle module components are in particular conceived for being assembled on the respective base plate 1 thereof and meeting the respective casting conditions, for example withstanding the respective compressive stresses during the casting procedure.

(25) In corresponding implementations, the one or the plurality of guide components 5 and/or the ventilation component or components 6 and/or the one or the plurality of centring plates 7 are associated with the machine type-specific group MG1 of the not contour-imparting tool receptacle module components 2, and/or the slider component or components 4 are associated with the group MG2 of the not contour-imparting tool receptacle module components 2 that can be used in a machine type-spanning manner.

(26) As can be seen in particular by means of FIGS. 3 to 5, in the two system variants with different assembly orientations shown there in which the contour-imparting mould components 3 are in particular assembled on the base plate 1, the two different orientations P.sub.1, P.sub.2 are rotated in relation to one another about an axis 8 which is perpendicular to the base plate 1. The axis 8, as in the example shown, is preferably situated within the fastening region Bb, as can be seen from FIGS. 2 and 4. In the case of FIG. 3, the orientation P.sub.1 is aligned so as to be parallel to the sides of the base plate 1 and thus parallel to the horizontal or vertical, respectively, machine direction of the diecasting machine 13; in the case of FIGS. 4 and 5, the orientation P.sub.2 at least of the contour-imparting mould components 3 is oblique to the sides of the base plate 1. When required, this can be used for forming the casting contour 12 in a spatial position on the base plate 1 which is favourable with a view to optimizing the relevant casting parameters, in that the associated set 3.sub.1, 3.sub.2, . . . of contour-imparting mould components 3.sub.11 to 3.sub.1p, 3.sub.21 to 3.sub.2q, . . . is correspondingly assembled. Moreover, the displacement directions of slider guides of the slider components 4 can also be optimally chosen so as to match the shape of the cast part G1, G2, . . . to be cast, or the casting contour 12, respectively, in that the slider components 4 are assembled in the corresponding orientation on the base plate 1, for example.

(27) In advantageous embodiments, at least one of the sets 3.sub.1 of contour-imparting mould components 3.sub.11 to 3.sub.1p forms a mould insert 3 which is specified for assembling as a functional unit on the fastening side 1a of the base plate 1, and on the rear side 3a thereof that faces the base plate 1 has an ejector-related clearance 3b, wherein said base plate 1 in this case is typically the base plate 1 which is provided for the movable mould half because the ejection of the cast part usually takes place there, as has already been mentioned above in the context of the ejector mechanism 11. An embodiment of this type is illustrated in FIG. 7. An ejector plate unit 11a to which one or a plurality of ejector pins 11b are coupled for movement is able to be received so as to be axially movable in the ejector-related clearance 3b of this mould insert 3.

(28) The ejector plate unit 11a by way of an ejector coupling unit 11c is able to be releasably coupled to a base plate-side ejector plate actuator unit 11d. This means that the ejector plate unit 11a and thus the ejector pin or pins 11b, in the case of a mould insert 3 assembled on the base plate 1, are releasably coupled to the ejector plate actuator unit 11d and on account thereof are able to be driven by the ejector plate actuator unit 11d in order to carry out the desired axial ejector movement, this corresponding to the ejector mechanism 11 mentioned in the context of FIG. 2.

(29) The ejector-related clearance 3b can also be referred to as a so-called ejector box and contains all ejector components which are required for ejecting the cast part, to which end an axial lifting movement which is sufficient for reliably ejecting the cast part is provided for the axial movement. In the example shown, the ejector pins 11b by way of a mushroom-shaped head end are fixed between two thin ejector plates 11a1, 11a2 which form the ejector plate unit 11a. On account thereof, it is enabled in a simple manner that, in the case of a plurality of ejector pins 11b as in the example shown, all ejector pins 11b can be simultaneously displaced in an axial manner. The ejector coupling unit 11c is implemented in a manner which is known per se to the person skilled in the art, this not requiring any further explanation here, and enables the desired coupling of the ejector plate unit 11a to the ejector plate actuator unit 11d while assembling the mould insert 3 on the base plate 1. The translation of the axial drive movement, or of the associated axial ejector forces, respectively, from the ejector plate actuator unit 11d, which is preferably formed by a conventional universal ejector plate pack having a usual interface to a machine-proximal hydraulic system, in the example shown takes place by pushrods 15. The ejector coupling unit 11c is preferably specified so as to be able to be controlled from the insert side of the diecasting tool system and is preferably equipped with a suitable control intelligence which for this specific application is known per se to the person skilled in the art. For improved understanding it is to be mentioned that said insert side of the system in the view of FIG. 7 lies at the top, and the rear side of the diecasting tool system facing away therefrom lies at the bottom. The ejector coupling unit 11c is in particular specified for automatically establishing or releasing, respectively, the coupling between the ejector plate unit 11a and the ejector plate actuator unit 11d simultaneously with assembling or releasing the mould insert 3 on or from the base plate 1, respectively.

(30) In advantageous implementations, the ejector plate unit 11a is able to be preassembled on the functional unit of the mould insert 3, and can in this manner be held preassembled on the latter before the mould insert 3, in this case conjointly with the ejector plate unit 11a, is assembled on the base plate 1, as is also the case in the exemplary embodiment of FIG. 7.

(31) The assembling and releasing of the mould insert 3 on or from, respectively, the fastening side 1a of the base plate 1 in corresponding embodiments, as in the shown example of FIG. 7, can take place while using an actuatable retaining bolt unit 16. To this end, an implementation for the holding bolt unit 16 preferably having a plurality of retaining bolts which are to be attached and released in a correspondingly automated controllable manner can be used, as is known per se to the person skilled in the art and only schematically indicated in FIG. 7.

(32) In advantageous embodiments, the at least one slider component 4 and the associated set, for example the set 3.sub.1, of contour-imparting mould components, for example the mould components 3.sub.11 to 3.sub.1p, are specified for releasably holding the slider component 4 pre-assembled on the associated mould component or components, that is to say the mould insert 3 formed by the latter, as is visualized in an implementation according to FIG. 8. Especially to this end, a slider hydraulic unit 4c and further slider standard functional groups 4a, in particular in the form of guiding and locking components, as well as a slider attachment 4b, which likewise in a usual manner is embodied so as to be contour-imparting in a manner individual to the cast part and to this end interacts with the assembled set 3.sub.1 of contour-imparting mould components, that is to say with the mould insert 3 which is assembled for the cast part to be cast, are shown for the at least one slider component 4 as slider component parts, which are known per se to the person skilled in the art, in the fragmented sectional view of FIG. 8. In a manner analogous to FIG. 2, the base plates 1 for the fixed as well as the movable mould half and the associated mould insert 3, the latter being in each case assembled on the fastening side 1a of said base plates 1, are shown in fragments in FIG. 8.

(33) Said slider components and thus the slider component or components 4 in the example shown of FIG. 8 are overall connected to the respective mould insert 3 and additionally screw-fitted thereto by means of a respective anchoring cam 17 and assigned screw connections. On account thereof, additional fixing of the respective slider component 4 on the respective base plate 1, or the basic construction of the system, which proximal to the insert terminates at the respective base plate 1, respectively, is not required. Rather, the respective slider component 4 during the operation of the diecasting machine or of the diecasting tool system, respectively, can be supported in a self-acting manner on corresponding support face regions on the fastening side 1a of the respective base plate 1, so as to absorb pressure and compressive forces resulting therefrom during the mould filling procedure. On the other hand, the pre-assembling of the slider component or components 4 on the mould insert or inserts 3, or the set 3.sub.1 of contour-imparting mould components 3.sub.11 to 3.sub.1p that in each case form said mould insert 3, respectively, enables rapid tooling of the diecasting machine with the components of the diecasting tool system that are required for casting the respective desired cast part, without the basic construction of the system, that is to say the respective base plate 1 and the system components adjoining the latter on the rear side, having to be disassembled from that diecasting machine to this end.

(34) In corresponding embodiments, the invention moreover enables comparatively rapid and simple tooling and retooling of the diecasting machine when cast parts of another shape and/or size are to be cast. It suffices to this end that the respective set of contour-imparting mould components and the associated tool receptacle module components are assembled or disassembled, respectively, while the basic construction of the diecasting tool system, including the base plates, can be left unchanged. The entire tooling or retooling procedure, respectively, for changing tools when a cast part of another shape is to be cast, can take place completely from the insert side of the tool system, or the diecasting machine, respectively, without interventions for disassembling the basic construction, or assembling or disassembling measures on the basic construction, respectively, being required. The set of contour-imparting mould components in corresponding implementations can be provided so as to be pre-assembled, when required so as to include associated ejector components and slider components, and the functional unit thus formed can be incorporated as an entity in the diecasting machine and be assembled and fixed on the respective base plate from the tool insert side, preferably in an automated or partially automated manner and while using a corresponding actuatable retaining bolt unit with retaining bolts or alternative fastening means which are to be attached and released in an automated manner.

(35) As is highlighted by the exemplary embodiments shown and explained further above, the invention makes available an advantageously modular diecasting tool system which enables a modular and thus flexible and variable use of tool components which for casting cast parts of different shapes and/or in a different orientation of the casting contour in terms of the machine directions of the diecasting machine are able to be assembled on a base plate. On account thereof, the invention offers advantages in particular also for the casting of prototypes and the low-volume production of cast parts.

(36) The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
