Definitions
- the invention relates to a device for releasably fastening a mold frame according to the preamble of claim 1.
- a known device of the type mentioned in DE-A-33 14 272 has between the molding table and the legs of the U-shaped molding frame a guide element provided with guide grooves, on which the molding frame rests by means of a lateral guide strip and which in the operating position holds the mold frame against the upper contact surfaces of the guide grooves by means of the wedge inserted underneath, in such a way that a largely planar surface is formed laterally beyond the mold surface.
- This design causes noticeably high design and manufacturing costs due to several components and / or additional guide elements.
- the wear that occurs with the known type of construction can only be corrected with great effort.
- the object of the invention is therefore to create a device of the type mentioned at the outset, which is characterized by simplicity and allows great freedom of dimensioning or a high degree of universal usability.
- this object is achieved in that the surface of the mold frame assigned to the mold filling opening and the contact surfaces provided on the mold table form a common plane.
- This construction principle enables a simplified arrangement of the form table and form frame within a press compared to the previous embodiments and enables the use of various lifting and clamping devices, for example hydraulic, pneumatic or mechanical lifting devices, wedges, spindle drives etc. Anchoring the mold frame in the mold table.
- the construction principle according to the invention proves to be advantageous in that the contact surface of the mold frame adjacent to the mold frame Filling slide can pass flush to the common plane formed from the molding table and molding frame.
- the configuration and arrangement of these large parts can thereby be considerably simplified and the rework in the case of mold wear can be reduced.
- the support surfaces of the mold frame form a shoulder with its surface, which is clamped between a contact surface of a guide groove and a mold carrier during the fastening.
- the keyway forming the keyway is in each case a contact surface of the guide grooves with a Formed bar, for the arrangement of which a step-like exception is provided in the molding table along the guide grooves and which are fastened to the molding table by means of screws.
- a plate is exchangeably attached to the support surface of the mold carrier facing the shoulder of the mold frame.
- 1 is a partial cross section through a molding table of a molding press acting in the vertical direction according to the line I-I in FIG. 2, but without a molding frame,
- Fig. 2 is a partial longitudinal section through the molding table of the press along the line II-II in Fig. 1 and
- FIG. 3 shows an enlarged section of the guide arrangement in FIG. 2.
- the proposed construction principle offers the person skilled in the art and user a wide range of alternative possibilities when using a device for releasably fastening a mold frame 2 to a mold table 3 of a press not shown in the drawing.
- FIG. 1 to 3 of the drawing show a device 1 for releasably fastening a mold frame 2 to a U-shaped mold table 3 of a molding press, for example one for the production of ceramic shaped stones.
- the opening of the U-shaped molding table 3 is located on the operating or front side of the press.
- the legs 4 of the molding table 3 extend from the rear 5 to the front columns (not visible) of the press.
- the inside of the legs 4 is provided with a guide groove 6 for anchoring the mold frame 2, these guide grooves 6 being er ⁇ along the
- the mold carriers 12 used for this purpose have on their rear side a stepped cam 15 which can be moved in a vertical guideway 14 and which is guided by a lockable guide rod 16 which is inserted into the mold table 3 from below and passes through the cam 15 of the mold carrier 12 is held in the guideway 14.
- the guide rod 16 is secured by a thread 17 at the rear end.
- the two mold carriers 12 provided for each side of the guide arrangement are provided with a groove 18 corresponding to the wedge pitch, into each of which a wedge 13 is driven from the outside by means of a hydraulic drive element 19.
- a strip 20 is provided in a prismatic recess 21 on the forming table 3, which is fastened by means of screws 22.
- the mold carrier 12 receiving the mold frame 2 on the shoulders 11 has a protective plate 24 on its upper side. Before the form frame 2 is anchored, it is moved into the rear position when the wedge 13 is retracted via transport 25 and guide rollers 26, which are freely rotatably supported in the legs 4 of the shaping table 3, and is then moved in by the subsequently driven wedges 13 the operating situation increased.
- the mold frame 2 stands with its lateral edge on the surfaces 7 of the guide grooves 6, which are formed by bulging on the legs 4
- protruding ribs 27 are formed.
- the wedges 13 are first loosened, so that the mold frame 2 comes to rest on the guide 26 and transport rollers 26.

Abstract
Dans un dispositif pour la fixation amovible d'un cadre de moulage (2) à une table de moulage (3) en U d'une presse, le cadre de moulage (2) peut être inséré dans des rainures de guidage (6) ménagées dans la table de moulage (3) et être fixé par des coins (13). Des rainures de guidage (6) sont ménagées sur les côtés (4) de la table de moulage (3) de sorte que la surface (9) du cadre de moulage (2) sur laquelle se trouve l'orifice de remplissage du moule et les faces de réglage (7, 8) des rainures de guidage (6) soient co-planaires.In a device for the removable attachment of a molding frame (2) to a U-shaped molding table (3) of a press, the molding frame (2) can be inserted into guide grooves (6) provided in the molding table (3) and be fixed by wedges (13). Guide grooves (6) are provided on the sides (4) of the molding table (3) so that the surface (9) of the molding frame (2) on which the mold filling hole is located and the adjustment faces (7, 8) of the guide grooves (6) are co-planar.
