ABSTRACT:
A molded article ejection device for use in conjunction with a multistation molding machine. The multistation molding machine has at least a first molding station defined between a first mold platen and a second mold platen and a second molding station defined between the second mold platen and a third mold platen, a mechanism for opening and closing the molding stations, and tie bars for connecting the first, second and third mold platens. Ejection devices are used for ejecting molded articles from each of the first and second molding stations and a linkage is used for connecting a plurality of the ejection devices and translating movement of at least one ejection device to at least one other ejection device. A motive mechanism is used for actuating the ejection devices, wherein the motive mechanism is independent of the mechanism for opening and closing.
