Pin Type Accelerated Ejector – Actuation


After molding, the ejection half of the mold base travels back until it reaches its stop position. The ejector rod then forces the ejector assembly forward. The actuating rack of the accelerated ejector contacts the actuating stud, forcing the pinion gear to rotate and raise the ejector pin rack and pin up. The accelerate ejector loosens the part before the pins in the ejector plate assembly make contact. This extra push can help the molded part clear its core safely and orient the part. The racks are forced to return to their original position by the actuating rack making contact with the bumper stud as the mold closes.
