Injection molding apparatus with alternately moved metal molds

摘要

An injection molding machine is provided with two sets of metal molds each including a stationary and movable metal molds. The two sets are mounted on a supporting plate which is moved in a direction perpendicular to the axis of an injection cylinder. Thus by reciprocating the supporting plate the two sets of the metal molds are alternately moved into and out of the injection molding machine.
