Abstract
An injection molding apparatus including an injection manifold having a manifold melt channel, a mold plate having a mold bore, and a hot runner nozzle located in the mold bore and having a nozzle melt channel. A mold insert including a melt channel includes an upper end adjacent the nozzle, a first outer surface adjacent the upper end, and a lower portion including a second outer surface, wherein the second outer surface is in sealing contact with an inner surface of the mold plate. A mold gate insert retainer includes an inner surface surrounding the first outer surface of the mold gate insert and a threaded outer surface for mating with a threaded inner surface of the nozzle. The first outer surface of the mold gate insert and the inner surface of the mold gate insert retainer are non-threaded. A lower end surface of the mold gate insert may form a wall of the mold cavity and may be angled.
