Abstract
A blow pin assembly for a mold of a rotary blow molding machine includes a base, a carriage supported by and movable relative to the base, a sub-base supported by and movable relative to the carriage, and a blow pin mounted to the sub-base for movement between a home position and a mold-engaging position. The blow pin is constructed with a low profile to clear an extruder head above the mold. This permits a method of forming a blow molded product to be used wherein the blow pin is inserted into the mold (and a parison in the mold), while the mold is at the extrusion workstation of the blow molding machine or very nearly so.
