ABSTRACT:
Am improved press for molding ceramic material which has a base frame on which a first carrier is rigidly mounted and which fixedly supports a stationary punch. A stripper platen is slidably movably supported on said first carrier and is adapted to be reciprocated therein by third piston and cylinder means mounted in said first carrier. The stripper platen includes an annular chamber disposed around the stationary punch for receiving granular ceramic material from a hopper mounted in the base frame. A second carrier is also rigidly mounted in the base frame and supports first and second cylinder and piston means. The first cylinder and piston means serves to support a movable punch which exerts the main molding pressure on the ceramic material when the stationary and movable punch are in the molding position. The second cylinder and piston serve to move the movable punch towards and away from the stationary punch and to exert supplemental pressure on the movable punch during the molding process.
