Abstract
A guide pin assembly is described which unidirectional orients mold platens while permitting temperature compensating movement in a perpendicular direction. This is accomplished by using a guide pin and shoe that contact in one direction and permit movement in a perpendicular direction. A bushing containing preloaded bearings is disposed about the guide pin such that the bearings make contact with the shoe to reduce wear and permit the guide pin to slideably contact the shoe.
