ABSTRACT:
An injection molding apparatus for forming plastic items employs a mold formed of tool members which mate to form a mold cavity. A mold core assembly includes a pull core adapted to extend into the mold cavity and a core support member from which the pull core depends. A nozzle is provided for introducing liquid plastic into a runner which communicates with the mold cavity. The nozzle has a retracted position and an injection position. The nozzle is attached to the core support member such that movement of the nozzle between the retracted position and the injection position causes movement of the pull core, and such that fluid may pass from the nozzle into the runner. The nozzle may be attached to the core support member in a manner to allow the pull core to move laterally with respect to said nozzle.
