Abstract: An injection molding assembly for molding plastic parts in mold cavities defined by separable mold parts attached to stationary and movable platens of the assembly. A plastic locating ring is attached to one of the mold parts and is disposed in an opening in the stationary platen for positioning the mold parts relative to the stationary platen and an injection nozzle assembly disposed in the opening of the stationary platen. The locating ring has an outer peripheral surface including a tapered portion and an adjacent axially extending portion whereby the tapered portion guides or leads the axially extending portion into the opening in the stationary platen. The locating ring is defined by inner and outer annular walls integrally interconnected by a base wall and radially extending ribs. The inner wall defines an inclined surface in a central opening for facilitating molten plastic run-off.
