Molding apparatus

In molding apparatus for producing a molding from a multi-component plastic, such as polyurethane, said apparatus including a stand;

• two mold holders arranged on said stand;
• two mold parts each affixed, respectively, to one of said mold holders;
• at least one mold holder being movable with respect to the other so as to bring its associated mold part to a first position in which the two mold parts are at a short distance apart;
• said mold holders having back surfaces provided on their sides facing away from their respective mold parts and extending substantially transversely to the direction of the closing movement of said movable mold holder;
• a propping system mounted movably in the stand comprising propping elements which can be brought into engagement with said back surfaces when said mold parts are in said first position;
• and jacking means arranged on at least one mold holder, by which the mold parts can be brought closer together and pressed together in a second position with the propping system engaged,
• the improvement wherein said propping elements are levers which are affixed to at least one pair of contrarily rotatable shafts that are journaled in said stand on the side of a movable mold holder that faces away from said mold parts, such that said levers can be laid down in said stand substantially transversely to the direction of closing movement and can be rotated such that their end faces are brought into engagement with at least one of said back surfaces.
