DETAILED DESCRIPTION OF THE INVENTION

(12) FIG. 1 shows a partial view from below of a mold frame 51 of a first variant embodiment of a mold 1.

(13) FIG. 2 shows a partial view from below of a mold insert 101 and of an insert body 101a of the mold insert 101 of the mold 1, of which the mold frame 51 can be seen in FIG. 1.

(14) In FIG. 1, the observer is looking at a lower side 52 of the mold frame 51 and, in FIG. 2, the observer is looking at a lower side 102 of the mold insert 101. Both lower sides 52, 102 form a lower side 2 of the mold 1.

(15) FIG. 3 shows a section through the mold frame 51 shown in FIG. 1, corresponding to the section line III-III. In the section, the lower side 52 of the mold frame 51 faces upward corresponding to the position which the mold frame 51 takes up in FIG. 1. The mold frame 51 comprises a frame body 51a and teeth 53a to 53c and 54a which are fitted on the latter, wherein the teeth 53a to 53c arranged on a longitudinal side 55 of the mold frame 51 or of the frame body 51a form a first row of teeth 53, and wherein the tooth 54a arranged on a transverse side 56 of the mold frame 51 is part of a second row of teeth 54. A further row of teeth is arranged on a second longitudinal side (not illustrated) lying opposite the first longitudinal side 55. Furthermore, a further row of teeth is arranged on a second transverse side (not illustrated) lying opposite the first transverse side 56. Recesses 57a to 57d and 58a, 58b are formed between the teeth 53a to 53c and 54a.

(16) FIG. 4 shows a section through the mold insert 101 shown in FIG. 2, corresponding to a section line IV-IV. In the section, the lower side 102 of the mold insert 101 faces upward corresponding to the position which the mold insert 101 takes up in FIG. 2. Teeth 103a to 103d and 104a to 104c are formed on the mold insert 101, wherein the teeth 103a to 103d arranged on a longitudinal side 105 of the mold insert 101 form a first row of teeth 103, and wherein the teeth 104a to 104c arranged on a transverse side 106 of the mold insert 101 are part of a second row of teeth 104. A further row of teeth is arranged on a second longitudinal side (not illustrated) lying opposite the first longitudinal side 105. Furthermore, a further row of teeth is arranged on a second transverse side (not illustrated) lying opposite the first transverse side 106. Recesses 107a to 107c and 108a, 108b are formed between the teeth 103a to 103d and 104a to 104c, respectively. The mold insert 101 furthermore only partially shows mold cavities 109, denoted by reference signs, in which molded blocks made of concrete can be produced when the mold 1 is assembled and rests with its mold lower side 2 on a production base. In order to produce the molded blocks, the mold cavities 109 are then filled with liquid concrete. The latter is shaped and compressed by punches entering the mold cavities 109 and by vibrations introduced via the production bases. The mold is subsequently lifted off the production base, and therefore the molded blocks remain on the production base and can be removed.

(17) An overall view of FIGS. 1 and 2 and of FIGS. 3 and 4 reveals that, in the assembled state of mold frame 51 and mold insert 101, the teeth 53a to 53c, 54a of the rows of teeth 53, 54 of the mold frame 51 engage in the recesses 107a to 107c, 108a, 108b of the mold insert 101, and the teeth 103a to 103d, 104a to 104c of the rows of teeth 103, 104 of the mold insert 101 engage in the recesses 57a to 57d, 58a, 58b of the mold frame 51. The mold insert 101 is thereby held in the mold frame 51 in such a manner that the mold insert 101 can neither be moved relative to the mold frame 51 out of the plane of the drawing nor into the plane of the drawingwhen looking at FIGS. 1 and 2. Of course, installation of the mold insert 101 shown in FIG. 2 into a receiving space 59 of the mold frame 51 shown in FIG. 1 is possible only when the teeth 53a to 53c and 54a are removed from the mold frame 51. For mounting from above in the arrow direction z, with respect to FIGS. 3 and 4, the mold insert 101 is placed into the receiving space 59 of the mold frame 51, the lower side 52 of which faces upward. The mold frame 51 lies with an upper side 60 on a base U. After insertion, the mold insert 101 likewise lies again with an upper side 110 on the base U. Following the insertion, the teeth 53a to 53c, 54a of the mold frame 51 are then screwed to the mold frame 51 by securing means 61 which are in the form of screws 62. For this purpose, each tooth 53a to 53c, 54a of the mold frame 51 has a step-shaped through bore 63 and, for this purpose, the mold frame 51 in the region of each tooth 53a to 53c, 54a has a threaded bore 64 into which the screw 62 is screwed in the fully fitted state. In the fully fitted state, the teeth 103a to 103d, 104a to 104c of the mold insert 101 then preventwith respect to FIGS. 3 and 4the mold frame 51 from being able to be lifted upward from the mold insert 101 in the arrow direction z. In the fully fitted state, the teeth 53a to 53c, 54a of the mold frame 51 then preventwith respect to FIGS. 3 and 4the mold insert 101 from being able to be lifted upward from the mold frame 51 in the arrow direction z. By this means, the mold insert 101 is then rigidly connected to the mold frame 51. The recesses 57a to 57d, 58a, 58b of the mold frame 51 and the recesses 107a to 107c, 108a, 108b of the mold insert 101 are open to the lower side 2 of the mold. For explanatory purposes, the tooth 53c is shown in FIG. 2, and therefore it can be seen how the tooth 53 engages in the recess 107c and rests on the mold insert 101.

(18) The interaction of the mold frame 51 with the mold insert 101 is explained once again with reference to FIGS. 5 to 9. Here, the mold frame 51 and the mold insert 101 are oriented in such a manner that they rest with their lower sides 52 and 102, respectively, on the base U.

(19) FIGS. 5 to 9 show diverse further sections through the mold frame 51 or through the mold frame 51 and the mold insert 101, wherein, in these illustrations, the mold frame 51 or the mold frame 51 and the mold insert 101 are shown in a position which is turned through 180 in relation to the sectional illustrations of FIGS. 3 and 4 and in which the mold frame 51 rests with its lower side 52 on the base U or in which the mold frame 51 and the mold insert 101 rest with their lower sides 52 and 102, respectively, on the base U.

(20) FIG. 5 once again shows a section, with respect to FIG. 1, corresponding to the section line through the mold frame 51 shown in FIG. 1, with the tooth 53a not being illustrated in FIG. 5.

(21) Analogously to the section illustrated in FIG. 5, FIG. 6 shows a section through the mold 1 with the mold insert 101 inserted into the receiving space 59 of the mold frame 51, wherein the tooth 53a (see FIG. 1) is not yet fitted on the mold frame 51. The recess 107a which opens to the lower side 102 of the mold insert 101 and in which the tooth, not illustrated, can engage can be seen on the mold insert 101.

(22) FIG. 7 then shows the illustration of FIG. 6, wherein the tooth 53a is now fastened to the mold frame 51 by means of the screw 62 and engages in the recess 107a (see FIG. 6).

(23) FIG. 8 shows a further section, with respect to FIG. 5, through the mold frame 51 corresponding to the section line VIII-VIII which is illustrated in FIG. 1 and which runs in the region of the recess 57b of the mold frame 51. The recess 57b opens not only toward the mold insert 101 (see FIG. 9), but also toward the base U on the lower side 52 of the mold frame 51, and therefore the mold insert 101 can be pushed from below in the arrow direction z into the receiving space 59 of the mold frame 51, or the mold frame 51 can be placed from above in arrow direction z on the mold insert 101, before the teeth 53a to 53c, 54a are then screwed to the mold frame 51.

(24) Analogously to FIGS. 6 and 7, FIG. 9 shows the mold 1 in the region of the section illustrated in FIG. 8, wherein the mold insert 101 is now received in the receiving space 59 of the mold frame 1. It can be seen in this illustration how the tooth 103b of the mold insert 101 engages in the recess 57b.

(25) FIG. 10 finally shows a second variant embodiment of a mold 201. The mold 201 is illustrated in an exploded view, wherein the mold 201 comprises a mold frame 251 and a mold insert 301, and wherein the mold frame 251 is shown rotated in relation to the mold insert 301 such that a longitudinal side 255 of the mold frame 251 and a longitudinal side 305 of the mold insert 301 are readily visible. A mold cavity 309 of the mold insert 301 can likewise be seen. As indicated by the arrows A, B, C and D, the longitudinal side 255 and the longitudinal side 305 lie opposite each other in the assembled state of the mold 201, in which the mold insert 301 is placed into a receiving space 259 of the mold frame 251.

(26) The mold frame 251 comprises teeth 253a and 253b and also recesses 257a and 257b on its longitudinal side 255. The teeth 253a, 253b are connected nonreleasably to a frame body 251a of the mold frame 251. The recesses 257a and 257b are formed on the frame body 251a and open to the longitudinal side 255 and to a lower side 252 of the mold frame 251. Since the frame body 251a annularly encircles the receiving space and a further longitudinal side (not illustrated) of the mold frame 251 lying opposite the longitudinal side 255 of the mold frame 251 is formed comparably to the longitudinal side 255, the arrows A to D do not symbolize pushing together, but merely indicate the manner in which the mold frame 251 and the mold insert 301 interact in the fully assembled state of the mold 201. The mounting or the assembly of the mold 201 is explained in more detail further below. A further longitudinal side (not illustrated) of the mold insert 301 that lies opposite the longitudinal side 305 of the cuboidal mold insert 301 is formed comparably to the longitudinal side 305 and interacts correspondingly with the longitudinal side (not illustrated) of the mold frame 201. Optionally, as shown in the first variant embodiment, rows of teeth and recesses can be provided on one or on both transverse sides of the mold frame and of the mold insert, and therefore the mold insert is held not only on two opposite sides, but on a total of three sides or four sides in a form-fitting manner in the mold frame.

(27) For the mounting, teeth 303a, 303b which can be screwed to an insert body 301a of the mold insert 301 are removed therefrom and the insert body 301a is placed from above in arrow direction z into the receiving space 259 of the mold frame 251, wherein the longitudinal side 305 of the mold insert 301 is oriented here parallel to the longitudinal side 255 of the mold frame 251. During the insertion, the teeth 253a, 253b are then received by recesses 307a, 307b which are open to the longitudinal side 305 and to a lower side 302 of the mold insert 301. Subsequently, the teeth 303a, 303b of the mold insert 301 are inserted from below into the recesses 257a, 257b of the mold frame 251 and into tooth receptacles 321a, 321b of the mold insert 301, the tooth receptacles corresponding to the recesses and being formed in the insert body 301a. In the fully fitted state, the teeth 303a, 303b are screwed to the insert body 301a with screws 312 which are each inserted from below in arrow direction z into a through bore 313 of the teeth 303a, 303b and are screwed into threaded bores 314 which are formed in the insert body 301a. Accordingly, in the fully mounted state of the mold 201, a row of teeth 253 of the mold frame 251 and a row of teeth 303 of the mold insert 301 then lie offset opposite one another.

(28) According to a variant embodiment of the present invention, it is also provided that the tooth receptacles 321a, 321b and the recesses 307a, 307b merge directly into one another and the separating webs 322 shown in FIG. 10 are omitted. In such an embodiment, it can also be provided that the teeth of the mold insert and the teeth of the mold frame are dimensioned in such a manner that they lie laterally against one another in the fully mounted state of the mold.
