Abstract

PURPOSE:To produce in a good yield a molded article having an embedded reinforcer covered entirely with a plastic material having a uniform thickness, by injecting the plastic material into a mold while keeping the reinforcer supported at its sides and rear by two movable supporting members. CONSTITUTION:After a reinforcing member 13 is supported by a second supporting member 6 provided in a moving mold 2 and the first supporting member 4 attached to the member 6 through a spring 5, the moving mold 2 and a stationary mold 1 are closed, and a plastic material in the molten and fluid state is injected into a cavity 13 thus formed through an injection opening 12. As the injected plastic material is filled into the cavity 13, it pushes the first supporting member 4 rearward against the spring 5 and then pushes the second supporting member 6 rearward against the a spring 10 to cover the reinforcer 3 entirely. Thereafter the plastic material is cured.
