ABSTRACT:
An injection molding machine utilizing a multiple plate die which is provided with a positive acting runner ejector. The runner ejector is provided with a tubular head extending into a cavity at a face of one of the die plates in which a runner forms so that the runner is molded on the head of the tubular member. The tubular member is moved by an air cylinder in the direction of die plate opening for pulling the runner clear of die surfaces. A plunger rod within the tubular member is moved lengthwise of the tubular member to mechanically release the runner from the head of the tubular member. Air under pressure is projected along the tubular member around the plunger rod to cause jettisoning of the runner from the multiple plate die.
