Ejector system for a plastics injection machine has an offset linear motor driving an ejector pin through a lever arrangement

摘要

An ejector pin (41) is moved through the center of a moving tool clamping platen by an actuator. The actuator is a linear motor (21) mounted outside the central axis(I) of the machine on the moving platen (11). A link arrangement (30) transfers force from the linear motor to the ejector pin.
