Abstract

See full text

A pivot casting component used in an apparatus for extrusion blow molding polyethylene teraphthalate (“PET”) is disclosed. The pivot casting is designed to provide increased strength and increased reliability over prior components with the blow mold clamping linkage system. Prior art pivot elements were designed and fabricated from separate elements such that weak points, and stress concentration points were created. Such weak points resulted in the pivot element being a weak component in the blow mold clamping linkage system. The inventive pivot casting is cast as a single component from higher strength materials, with an improved geometry to increase component strength, durability and overall system reliability. In a preferred embodiment, the air side pivot casting is formed from 80-55-06 ductile iron resulting in a 40% increase in tensile strength over prior pivot components.
