Ejector device for use in injection molding machine for ejecting half- or completely cured injection molded parts from cavity, has reinforcing device for reinforcing ejection force acting on parts to increased auxiliary-ejection force

摘要

The device (1) has ejection pins (4) attached to a movable ejector plate (2) and for ejecting injection molded parts (5) from a cavity (6) of an injection molding tool (7). The pins are drivable by a drive device (3), and the plate is movable with a predetermined normal-ejection force acting on the molded parts by the drive device. A reinforcing device (8) reinforces an ejection force acting on the molded parts to an increased auxiliary-ejection force for ejecting the jammed molded parts by the normal-ejection force that is adjustable by the drive device during existence of the jammed parts.
