Abstract: A cam follower slide component used in an apparatus for extrusion blow molding polyethylene teraphthalate is disclosed. The cam follower slide component is designed to include disc springs positioned about a spindle that is in turn located along the slide direction of the cam follower. With the inclusion of disc springs, the cam follower slide is capable of absorbing certain excessive forces within the blow mold clamping linkage system that may develop during irregular blow mold process conditions. In a preferred embodiment, the cam follower slide component includes the ability to adjust the spring force of the disc springs to allow for a variation in allowable excess system linkage forces.

Abstract: A bracket for linking guide rods to a wheel of a vertical blow molding machine and a system for blow molding containers and a mechanism for opening and closing a pair of mold halves linked to the wheel of the vertical blow molding machine using the bracket, comprising a first portion and a second portion made of iron, a plurality of pivot apertures, and a plurality of guide rod apertures for receiving the guide rods.

Abstract: The present invention relates to a hollow blow needle for introducing a pressurized fluid into an extruded parison enclosed by two mold halves, the needle comprising: a body portion having an inner first diameter; a neck portion having an inner second diameter, wherein the inner second diameter is less than the inner first diameter; and a tip portion comprising a first angled portion, a second angled portion that is a different angle relative to the first angled portion, and an orifice.
