Abstract
Injection blow molding equipment for the production of hollow articles wherein cores are axially inserted in blow molds and blank molds is disclosed. Compact core assemblies and fluid supply systems integral with the platens allow the mold parts to be mounted on the surfaces of opposed, relatively movable platens. Partible neck rings associated with each core open divergently outwardly as the blow mold and core separate, to shorten machine cycle time. A manifold, supplied with cooling fluid from the periphery of a core mounting plate, distributes heat transfer fluid to the core assemblies for cooling the neck rings. In one embodiment, mating blow mold sections are mounted on contra-oscillatable mounting members and are opened and closed by arcuate movement of the mounting members.
