ABSTRACT:
An integrated plastic injection mold and blow mold machine includes an injection mold assembly having a cooled exterior mold assembly connected to a plastic injector for injecting plastic. A cooled core assembly is positionable within the cooled exterior mold assembly to define a mold cavity for accepting injected plastic from the plastic injector to form a parison. To allow transfer of the parison to a blow mold assembly, the cooled core assembly is movable with respect to the cooled exterior mold assembly. A thread split holds the parison and is used to first form the neck of a parison, and then move the parison from the injection mold assembly to the blow mold assembly. In addition, the parison is formed by use of a removable cooled core that is movable with respect to the thread split. The removable cooled core accommodates a poppet valve through which air can be introduced to facilitate separation of the parison from the removable cooled core while still leaving the parison held in position by the thread split. The poppet valve is cooled through direct or indirect contact with a cooling medium so that the head of the poppet valve and the plastic adjacent thereto is adequately cooled.
