Abstract
A compression mold for manufacture of a fiber-reinforced composite vehicle wheel that has a circumferential array of radially reciprocable rim mold sections, a lower disc mold section affixed to a mold base, and an upper disc mold section axially reciprocable with respect to the lower disc mold section from an upper or retracted position to a lower or closed position in which opposing surfaces of the various mold sections form a wheel mold cavity. The radially reciprocable rim mold sections are slidably mounted on a retainer which is carried by springs above the mold base surrounding the lower disc mold section and are engaged by the upper disc mold section during downward motion of the latter so that the upper disc mold section and the rim mold sections move conjointly with respect to the lower disc mold section toward the closed cavity-defining position of all mold sections.
