ABSTRACT:
Ejector pins are carried by an ejector device, and are releasably secured in said device by latch means. Release of the ejector pins by said latch affords withdrawal, or replacement, or redistribution of said pins through a mold support plate, without removal of the ejector device from the molding machine assembly. A plurality of holes in the support plate coincides in number and distribution with a plurality of sockets in a carriage plate in the ejector device, to afford alternative groupings of ejector pins to accommodate various mold contours of interchangeable mold plates.
