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.
[0058] 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.
[0059] 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, . . . 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 31.sub.p, 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
[0060] In advantageous embodiments, the fastening grid is formed by a two-dimensional field of the fastening points 14, as in the shown example of
[0061] 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.
[0062] 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.
[0063] 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
[0064] 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
[0065] 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
[0066] 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.
[0067] 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.
[0068] As can be seen in particular by means of
[0069] 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
[0070] 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
[0071] 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
[0072] 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
[0073] 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
[0074] 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
[0075] Said slider components and thus the slider component or components 4 in the example shown of
[0076] 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.
[0077] 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.
[0078] 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.
