Abstract
A device to connect an ejector device, of an injection molding machine, to an ejector pin of a mold used with the machine. The device has a holder with jaws which are radially movable therein for clamping and unclamping the ejector pin introduced into the holder. A spring urges the jaws towards the clamping position, and the jaws can be moved to the unclamping position by a manually operable actuator. A latch can hold the jaws in the unclamped position, and the holder has a releasing element mounted in it and arranged so that when actuated by the ejector pin it allows the spring to bring the jaws into the clamping position to lock the ejector pin.
Claims5
