Device for coupling between an ejection plate and an actuating bar on a pressure casting machine

摘要

The device for coupling according to the invention comprises automatic hitching means comprising a series of hooks 26 guided radially in guiding grooves 30 formed in the actuating bar 10, and whose free ends 42 are equipped with conical cam surfaces 48 interacting with the conical lateral face 44 of a throat 46 formed in the ejection plate 12, 22 to provide positioning and locking in position of the plate 12 on the bar 10. The hooks 26 are actuated by a double-action hydraulic ram 50 arranged in the body of the actuating bar 10. Application to the automatic hitching of ejection plates in pressure casting machines. <IMAGE>
