ABSTRACT:
The present invention relates to an apparatus for producing molded plastic articles which is capable of simultaneously producing and cooling the plastic articles. The apparatus has a stationary mold half having at least one cavity, at least two mating mold portions, each having at least one core element, mounted to a movable carrier plate which aligns a first one of the mating mold portions with the stationary mold half and positions a second of the mating mold portions in a cooling position, a device for cooling the molded plastic article(s) when in the cooling position, and a device for moving the carrier plate along a first axis so that the aligned mold portion abuts the stationary mold half and the second mating mold portion simultaneously brings each plastic article(s) thereon into contact with the cooling device. The carrier plate is also rotatable about an axis parallel to the first axis to permit different ones of the mating mold portions to assume the aligned position during different molding cycles.
