摘要:
A two-color molding equipment for shaping a two-color molded product by placing a film in primary mold tool configured by a fixed mold and a movable mold, injecting a resin into a first cavity formed by closing the molds to shape a primary molded piece, shifting the primary molded piece provided with the film to secondary mold tool configured by the fixed mold and the movable mold, and injecting a resin into a second cavity formed by closing the molds to shape a secondary molded piece, the two-color molded product composed of an integrated combination of the primary molded piece, the secondary molded piece, and the film interposed therebetween, wherein the first cavity is configured to shape the primary molded piece to be smaller than the film so that a part of the film protrudes from the primary molded piece, and a wall surface located at the protruding portion of the film to constitute the first cavity is provided with a convex portion that restricts mold shrinkage of the film protruding portion in the primary molded piece.
