Abstract
An ejector apparatus for an injection molding machine, includes ejector pins mounted to a movable ejector plate and drivable by a drive device for ejecting injection molded parts from a cavity of an injection molding tool. The ejector plate is displaceable by the drive device with a given normal ejector force acting on an injection molded part. There is provided a reinforcing mechanism which, when there is a jammed injection molded part, reinforces the ejector force acting on the injection molded part to an increased additional ejector force for ejecting the jammed injection molded part above the given normal ejector force which can be or is made available by the drive device.
