ABSTRACT:
Apparatus for molding a composite metal-elastomer styled wheel in which a middle mold part consists of a metal wheel disc and rim subassembly. A base mold part seats against the outboard face of the metal wheel in the closed condition of the mold and has a mold cavity surface to provide an ornamental configuration for the outboard face of the plastic body of the composite wheel. A clamp seats against the inboard face of the middle mold part to urge the middle part into sealing engagement with the base mold part. The mold parts are axially separable from one another to open the molding apparatus to clear the middle mold part from said clamp and base mold parts. The clamp includes a funnel adapted for registry with a liquid reaction mixture injection nozzle coupled with injecting mixing apparatus. The funnel has a nozzle passage registering with a pour opening in the disc in the closed condition of the mold. A sprue pin is affixed to the base mold part in juxtaposed relation to the disc pour opening and cooperates with the margin of the pour opening to define a restricted access opening to the mold cavity during the injection pour of the urethane reaction mixture.
