A quick change blow mold shell assembly is disclosed. The blow mold shell assembly includes a carrier plate and a blow mold half shell for being fastened to the carrier plate. A first slotted opening is defined in an edge of the carrier plate, and a corresponding second slotted opening is defined in an edge of the blow mold half shell. The first and second openings are placed in registry with one another as the shell is positioned on its carrier plate. A fastener clip is also provided, the clip being sized and shaped to be received in each one of the respective openings, and being constructed and arranged to align the first and second openings with respect to one another, to draw the shell snugly against the carrier plate, and to fasten the shell to its carrier plate as a fastener is passed through the clip and into the carrier plate.

A blow mold assembly is provided that comprises a blow mold shell, a mold holder and a mold holding assembly. The blow mold shell having a first annular groove disposed within the lengthwise exterior surface of the shell. The first annular groove serves as a mating surface for a support harness that positions the mold shell within the blow mold assembly. Additionally, the blow mold shell may comprise a shoulder insert that may include an independent cooling channel. The blow mold assembly comprises a mold holder that includes arcuate interior surfaces and arcuate exterior surfaces so as to create a concentric blow mold holder. The mold holder may comprise a pressure compensation element that is capable of compensating for the pressure build-up within the mold shell during the blow mold process. The blow mold assembly also comprises a blow molding holding assembly that comprises clamping brackets having arcuate inner surfaces for mating with the arcuate exterior surfaces of the mold holder or mold shell. The clamping brackets are pivotally driven by a cam apparatus within a blow-molding machine and serve to open and close the blow mold assembly as warranted by the fabrication process. The blow mold shell assembly may also comprise a mold shell and a mold holding assembly. In applications not requiring a mold holder, the mold holding assembly comprises clamping brackets having an arcuate inner surface and the arcuate inner surface of the clamping brackets are disposed circumferentially about the exterior surface of the blow mold shell. The invention also comprises the individual components of the blow holding assembly.

Blow mold shell and shell holder assembly for blow-molding machine

An improved blow mold shell, and a blow mold shell assembly, for use in blow molding containers is disclosed. The blow mold shell comprises an elongate unitary blow mold shell body defining a partial molding cavity, the partial molding cavity having a container neck forming portion and a container body forming portion. A first continuous cooling circuit is defined within the shell with respect to the neck forming portion of the molding cavity. A second separate, and independent, continuous cooling circuit is defined within the shell with respect to the body forming portion of the molding cavity. So constructed, the neck and body portions of a blow mold container may be separately cooled, and/or heat-treated, as desired, during the molding process to allow the sidewall portion of the container to be molded in as thin a sidewall section as possible in contrast to the neck portion of the container. The shell assembly is comprised of two substantially identical ones of the blow mold shells releasably mated to one another, and also includes a base assembly received at the second end of the blow mold shells. The base assembly defines a base portion of the molding cavity, and has a separate cooling circuit for cooling the base forming portion of the molding cavity.
