  • Patent number: 5295802
    Abstract: A gripper (2) for removing a molded workpiece (9) from the opened mold (1, 3) of a molding machine is coupled through a step-up drive transmission with the ejector (13, 15, 17) associated with the mold in such a manner that the ejector causes it to execute a movement away from the ejector in the same direction of motion as the ejector. The drive transmission can in particular have co-operating limit stops (45, 43) on the ejector and on the gripper, and one of these limit stops is mounted on a drive step-up lever (37). In another embodiment, the step-up drive transmission is designed as a hydraulic transmission.
