Abstract: An improved composite metal-elastomer styled automotive-type wheel with a three-dimensionally contoured ornamental outboard face formed by a plastic overlay body permanently adhered or affixed to the outboard face, and an improved molding apparatus and method for constructing such a wheel. A plastic overlay body has an annular row of outboard pockets disposed in radially offset, axially overlapping relation with a annular row of inboard pockets which in turn register with vent openings in the disc to thereby provide air passages through the wheel for brake ventilation. The outboard pockets preferably are disposed radially remote from the center of the wheel close to the wheel rim, and a relatively thin cross-section of plastic material is molded so as to overlie the outboard rim flange to provide a full-face appearance to the wheel.

Abstract: Method 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. There is a clamp which 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. The sprue pin is operable to restrict back-flow of the reaction material during gelation of the same in the cure cycle.

Abstract: A composite styled wheel having a metal wheel mounting disc and rim secured together and adapted to receive a tire thereon, and a plastic ornamental overlay body permanently affixed and covering at least a part of the outboard face of the disc and/or rim. The body is made of an elastomeric material, and its outboard face has a decorative contour exposed to view from the outboard side of the wheel. Hub cap retainer grooves or pockets are provided in the outboard face of the body adapted to individually yieldably engage and retain attachment prongs of a hub cap for removable attachment of the same to the wheel. Each of the grooves or pockets has an opening at an outboard face of the body with juxtaposed entrance edges spaced apart a distance less than a maximum transverse dimension of the associated prong to provide an interference fit therewith. Each groove or pocket also has an interior wall surface defining an undercut relationship relative to the opening edges.

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.
