ABSTRACT:
A cyclically operated injection plastic molding machine which contains a device for moving a mold insert into and out of a mold is illustrated. When the mold is closed, the mold insert is moved into it; but, before the mold is opened, the insert is removed from it. The machine also contains an electric eye device which senses the motion of a movable finger which is caused to move by the motion of an injected molded part formed by the machine.
