VORRICHTUNG ZUR ROTATIONS ANPASSUNG EINES MERKMALS EINER OPTISCHEN GIESSFORM AN DEM ANSCHNITT IN EINEM SPRITZGIESSVORRICHTUNG

摘要

A selectively, rotatably adjustable riser pin for aligning a predetermined characteristic on an asymmetrical mold surface with the gate of an injection molding machine for enhanced flow dynamics of the mold material across the mold surface. The riser pin is divided into two co-linear portions which are biased towards one another such that application of a predetermined torque will allow the front riser pin portion, which carries the mold tool, to be rotated independently of the back riser pin portion.
