ABSTRACT:
A coupling provides for the control of the ejection assembly of a mold. It consists of an ejection member fastened to this assembly and of a claw which can be adapted to control means in the injection press. A tip which is fastened to these means is extended by a rod around which there are mounted jaws, which can tilt and which are themselves surrounded by a sliding sleeve. In an advanced position, the sleeve maintains the jaws tightened so that they retain the head of the ejection lug. In the recessed position, the sleeve maintains the jaws spread out, so as to liberate the head.
