Abstract

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 snuggly 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.

providing a first opening in an edge of said mounting face of said carrier plate;
providing a second opening in an edge of said rear face of said mold shell such that said second opening will be in registry with said first opening along a mating surface generally defined by said rear face and said mounting face when said mold shell is assembled to said carrier plate;
providing a fastener clip sized and shaped to be received in each of said first and second openings;
providing a fastener configured to pass through said clip and into said carrier plate;
placing said fastener clip within each of said first and second openings;
inserting said fastener in a first direction through said clip and into said carrier plate;
progressively tightening said fastener such that said first and second openings are aligned and such that said rear face of said mold shell is drawn toward said mounting face of said carrier plate in a direction generally perpendicular to said first direction until said mold shell is drawn snugly against said carrier plate.
