摘要： This relates to an apparatus for injection molding preforms for beverage bottles wherein a minimum cycle time is involved. Cores over which thermoplastic material is injection molded to form preforms for use in the blow molding of bottles are provided in sets and carried by a rotary turret so that as soon as the injection molded thermoplastic material has sufficiently set to permit its transfer with its associated core out of an injection mold cavity, the apparatus may be actuated to remove first injection molded preforms and thereafter immediately present a new set of cores to the injection mold cavities. This provides ample time for the cooling of the preforms so that when removed from the cores they will not be unduly deformed. In accordance with the feasible use of the apparatus, plural preforms, on the order of twenty-four and greater, may be formed with a cycle time on the order of 10-12 seconds.
