Abstract
Molding units each having upper and lower molds are indexed through an injection station and then into an opening station. At the opening station, the lower mold of each unit first is opened and then is closed relative to the upper mold, the opening and closing of the lower mold being effected by an hydraulically actuated puller block adapted to be moved between raised and lowered positions. A shiftable yoke holds the puller block in a precisely established intermediate position while the molding units are being indexed into and out of the opening station.
