Abstract

PURPOSE:To obtain accurate facial accuracy of a metallic member, by fitting the inside of a cavity with the metallic member under a curved state corresponding to a quantity of a deformation due to shrinkage of synthetic resin. CONSTITUTION:The inside of a cavity 14 of a plastic molding mold for molding a molded product 12 provided integrally with a metallic member 12b is fitted with the metallic member 12b under a state where the same is curved in correspondence to a quantity of a deformation due to shrinkage of synthetic resin by injecting molten resin to the cavity 14 which is formed of a stationary mold 16 and movable mold 18. With this construction, even if the molten resin is shrinked thermally according as the molten resin is cooled and solidified, also the metallic member 12b is deformed according to the heat shrinkage and fitted integrally to a resin part under a flat state. In addition, the metallic member 12b is formed of SUS into an annular state and provided with a connecting hole 12c into which the molten resin flows at every predetermined interval.
