ABSTRACT:
A positioning device for positioning a slidable core in a movable insert of a die casting mold. The positioning device utilizes a rotary actuator coupled to a piston in a hydraulic cylinder to rotate the piston and in turn a cylinder rod. The cylinder rod is provided with a coupling member at an end distal the hydraulic cylinder for releasable coupling with the slidable core for axial movement of the slidable core. An adaptor block mounts the rotary actuator to the hydraulic cylinder. The adaptor block includes a stop for limiting rotation of the rotatable components of the positioning device.
