EJECTOR-DEVICE FOR INJECTION MOLDING MACHINE

摘要

PURPOSE:To obtain a large longitudinal champing die-device for an injection molding machine in which a metal die is made to be automatically and smoothly detachable and engagable, by automatically connecting the ejector mechanisms of the die to the ejector mechanism at the side of the injection molding machine. CONSTITUTION:An ejector-plate 16 capable of reciprocating by a constant stroke is equipped at the side of a movable disc 3. One end of said ejector plate 16 is fixed to the ejector plate 19 in the metal die arranged in a movable side- metal die 15 fixed to the movable disc 3. The connecting piece 22 engagable and detachable to the stud 20a at the tip of the ejector rod 20 protruding through the ejector plate 16 is arranged on the other end of the ejector plate 19.
