Abstract

A stamping press, as for stamping molded articles out of a plastic web wherein the articles are premolded, has a fixed stamping tool section accurately secured on the press frame and a movable tool section slidably mounted on fixed columns on the fixed tool section and connected by operating linkage to power driven devices on the frame, the linkage including adjustments for tool alignment, stroke and frequency. Push rods in the linkage transmit movement to the movable tool section from cam controlled rocker arms, and the push rods are removably hinged to the movable tool section to disconnect and remove the latter. Secondary devices such as ejectors and further tools are actuated in synchronism with the stamping tool.
