金型構造。[Scope of Claim for Utility Model Registration] A mold structure for compression molding a molded product body from a sheet-shaped resin material and forming a resin coat layer on the surface of the molded product body within the mold, comprising: a sheet-shaped resin material; A core mold on which the material is placed, and a vertical molding surface in which a discharge hole for the coating material for forming the coat layer opens at a part offset from the center of the mold, and extends substantially perpendicularly downward to the edge on the side where the discharge hole opens. The core mold and the cavity mold have a vertical molding surface extending substantially vertically downward from the edge of the cavity where the vertical molding surface is provided, and the molded product body. 1. A mold structure for resin molding, characterized in that a thin-walled molding section for molding a thin-walled section continuous to the thin-walled section, and an undercut molding section for molding an undercut section continuous to the lower end of the thin-walled section are formed.
