摘要： Apparatus, method and sealing means for liquid urethane reaction mixture injection molding of a composite styled metal and plastic vehicle wheel wherein a metal wheel subassembly serves as a preform between the separable mold parts in the mold apparatus and which is united with the plastic body molding material to form the composite wheel. One of the mold parts has a mold cavity surface operable in mold closed condition to define with the outboard face of the wheel subassembly a mold cavity adapted to provide an ornamental configuration for an outboard face of the plastic body of the composite wheel. A gas permeable and liquid infiltratable mold sealing membrane has a first portion thereof communicating with ambient atmosphere externally of the mold cavity and a second portion thereof communicating with the mold cavity. The membrane is made of fabric material comprising random fibers, calendered into sheet form and selected from the group consisting of polyethylene, polypropylene, Teflon coated polyethylene, and Teflon coated polypropylene fibers. The membrane has a gas permeability ranging between about one to twenty cubic feet of air per minute, and more particularly between about one to four cubic feet of air per minute. The membrane fabric material consists of fibers processed into coherent sheet form having a thickness ranging between about 0.01 inches to about 0.10 inches and having a weight in the order of about 15 ounces per square yard, and is heat seared on at least the side thereof juxtaposed to the mold cavity. The mold sealing membrane is operable to provide flow-through limited venting of gases from the mold cavity to ambient until the membrane seal is clogged by liquid reaction molding material infiltrate therein.

摘要： An elastomeric guard member for use with a vehicle wheel is disclosed. The wheel includes a wheel disc and rim. The wheel disc defines a plurality of circumferential openings. In prior art wheel assemblies, debris was apparent at the wheel openings. The elastomeric guard member is positioned in a circular configuration within the space to retard water and debris from entering the space and to present a better visual appearance.

摘要： A composite styled wheel has a rigid wheel backbone with a plastic overlay on an outboard face thereof. The wheel backbone is positioned in a lower mold to define a mold cavity therebetween, and an upper mold seals through apertures in the wheel backbone. The lower mold has a ring-shaped forming surface that selectively abuts the outboard flange edge of the wheel backbone, and a riser which selectively engages the wheel backbone, and selectively positions the outboard flange edge a spaced apart distance from the forming surface to define a venting space therebetween. A reactive urethane mixture is injected into the mold cavity to fill at least a portion of the same, and flow the mixture through the venting space to evacuate air from the mold cavity. Before the mixture is fully cured, the riser is actuated, the wheel backbone and lower mold are converged, so that the outboard flange edge abuts the forming surface to seal off the venting space, and form over at least a portion of the outboard flange edge, a smooth, skinned, mold-formed outer portion of the plastic overlay.
