ABSTRACT:
An ejector system for use in an injection molding machine comprises a plurality of rack gears and pinions gears that provide active alignment of plates within the ejector system. As unequal force is experienced in ejecting a molded item, the rack and pinion gears distribute the force to other areas of the ejector system plate, maintaining proper alignment of the plates within the ejector system.
