とする樹脂成形用金型構造。[Claims for Utility Model Registration] A structure of a mold for molding a resin molded product having an undercut portion projected inward, the mold having a directly above core and sliding along the directly above core in the direction in which the undercut portion protrudes. A molding groove is formed in at least the directly above core for demolding the undercut portion of the resin molded product by the inclined core, and for molding an inner surface rib formed on the inner surface of the resin molded product and extending in the demolding direction. A mold structure for resin molding, characterized in that the molding groove is formed with an undercut molding part that is inclined inward with respect to the demolding direction.
