Abstract

Apparatus and methods for a preform mold system include multiple preform core side modules having preform mold cores, a core side clamp plate connectable to a moving platen of an injection mold machine and operable to receive the preform core modules, multiple preform cavity side modules having preform mold cavities, each of the preform cavity side modules operable to matingly engage a respective core side module to form multiple preform molds having a respective preform design, and multiple ejector housing assemblies for connecting the core side modules to an ejector platen of the mold machine, each of the ejector housing assemblies corresponding to a respective core side module. The preform mold system may also include a manifold and valve gate assembly connectable to a stationary platen of an injection mold machine and operable to receive the cavity side modules and place the mold cavities in fluid communication with an injector of the mold machine to control the injection of fluidized plastic in a uniform flow into the preform molds, simultaneously.
