Definitions
- the invention relates to a device for releasably fastening a mold frame according to the preamble of patent 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, each with a guide element provided with guide grooves, on which the molding frame rests by means of a lateral guide bar and that in the operating position Holds the mold frame by the wedge inserted under it against the upper contact surfaces of the guide grooves, in such a way that a largely flat 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 design can only be corrected with great effort.
- the object of the invention is therefore to provide 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 molding table and molding frame within a press compared to the previous embodiments and allows the use of various lifting and clamping devices, for example hydraulic, pneumatic or mechanical lifting devices, wedges, spindle drives etc., for anchoring the molding frame in the molding table.
- various lifting and clamping devices for example hydraulic, pneumatic or mechanical lifting devices, wedges, spindle drives etc.
- the construction principle according to the invention proves to be advantageous in that the contact surface of the fill slide adjoining the mold frame turns out against it Form table and mold frame formed joint level can pass flush.
- the design 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 contact groove forming the keyway is in each case a contact surface of the guide grooves 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.
- the proposed construction principle offers the person skilled in the art and the user a wide selection of alternative possibilities when using a device for the detachable fastening of a molding frame 2 to a molding 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 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 running along the extending legs 4 and being recognizable in the figures by their lateral contact surfaces 7, 8. Between the contact surfaces 7, 8, the mold frame 2 is clamped on a shoulder 11 formed by its surface 9 and a support surface 10 on mold carriers 12 by means of wedges 13 in the operating position.
- the mold carriers 12 used for this purpose have on their rear side a stepped cam 15 which is movable in a vertical guideway 14 and which is held in the guideway 14 by a lockable guide rod 16 which is inserted into the mold table 3 from below and penetrates the cams 15 of the mold carriers 12 .
- the guide rod 16 is secured by a thread 17 at the rear end.
- the two mold carriers 12 each provided for one 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 bar 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.
- the mold frame 2 Before anchoring the mold frame 2, it is moved into the rear position with the wedge 13 retracted via transport 25 and guide rollers 26, which are freely rotatably mounted in the legs 4 of the mold table 3, and is raised into the operating position by the wedges 13 which are then driven in.
- the mold frame 2 With its lateral edge rests against the contact surfaces 7 of the guide grooves 6, which are formed by ribs 27 protruding in a bead-like manner on the legs 4.
- the wedges 13 are first loosened, so that the mold frame 2 comes to rest on the guide rollers 26 and transport rollers 26.
