Abstract
A coupling member for interconnecting a hydraulic ejector cylinder, of injection molding equipment, with a mold ejector system to insure that the mold ejector system of the mold is properly activated and returned to its fully retracted position prior to commencing a further injection molding cycle. The coupling member comprises a first elongate stud which is releasably couplable to a second elongate stud to form the coupling member. The first elongate stud has a head, at one end thereof, and the second elongate stud has a stud recessed portion, at a mating end thereof, for at least partially receiving the head. A locking mechanism, carried by the second elongate stud, allows engagement and disengagement of the head from the stud recessed portion, when in a first position, and secures the head at least partially within the stud recessed portion, when in a second position.
