  • Patent number: 4531961
    Abstract: Apparatus for manufacturing molded articles includes a plurality of mold section presses. A mold slide carriage of each press moves a mold among charge receiving, molding, and extraction stations. A charge is guided to the mold while at the receiving station by a trough, from a rotatable scoop. A mold clamp mechanism of drivable arms linked to the mold and wedgeable against cam blocks maintains the mold closed during molding. A mold plunger driven by a press head assembly mates the mold. A molded article is kicked up by a kick-up mechanism. A take-out mechanism rotates jaw members about two axes to grasp molded articles at the extraction station, lifting them to an article removal station.
