ABSTRACT:
An injection molding apparatus includes a manifold having a manifold melt channel for receiving a melt stream of moldable material under pressure and at least one nozzle having a nozzle melt channel in fluid communication with the manifold melt channel. The nozzle has an opening that intersects with the nozzle melt channel, the opening having a central axis that is at an angle with respect to a central axis of the nozzle. A nozzle tip is coupled to the nozzle at one end of the opening. A valve pin bushing is coupled to the nozzle at an end of the opening opposite the nozzle tip. A valve pin extends through the opening. A primary actuator is connected to the valve pin. A nozzle locator piece is connected to the nozzle for mating with a side plate to locate the nozzle with respect to the mold gate.
