Abstract

PURPOSE:To prevent the appearance from disfiguring by an outflow of raw material resin on the clearance part of the separate molding part and the body by a method wherein in the multiparts monoblock injection molding a separate molding parts control holing part, a knife part, a pressure holding part and such are prepared in a part of the mold. CONSTITUTION:In the injection molding of the body part 4, whereby a separate molding part 3 is partly wrapped in, a part of the female mold 1 is provided with a position control holding part 11 to saliently mold a knife part 12 biting the surroundings corresponding to the clearance part 31 of the separate molding part 3. Also on the male mold 2 the pressure holding parts 21 facing the knife parts 12 of the female mold 1 are partially saliently molded with proper intervals. When thereby the separate molding part 3 is set and locked and the resin is injected with pressure into the mold, the raw material resin is surely checked in this part, as the pressure holding part 21 is pressing the knife part 12, thus being stopped to flow out to the separate molding part 3 surface to gain monoblock molded goods with good appearance.
