ABSTRACT:
Apparatus for removing and/or placing a workpiece from or into an injection mold of an injection molding machine includes a fixed platen and a moving platen which have attached thereon respective half-molds. A toothed rack is firmly connected to the fixed platen and engages with a drive pinion of a globoid cam gear which is disposed on the moving platen or attached half-mold and has an output shaft for attachment of a gripper arm. To prevent the gripper arm from moving into an undesired position, when the injection mold is opened beyond a predefined distance, the toothed rack and the fixed platen are connected through the intervention of a detachable coupling, whereby a release mechanism is provided to disengage the coupling when a distance between the fixed and moving platens exceeds a predetermined value.
