Undercut processing mechanism, molding die and molded product

Abstract

An undercut processing mechanism is attached to and used in a molding die for forming a molded product having an undercut portion and allows the undercut portion, projecting in a direction intersecting a demolding direction of the molded product, to be demolded. The undercut processing mechanism includes: a holder attached to the molding die so as to be movable in a demolding direction of the molded product P; a sliding piece slidable relative to the holder and configured to form the undercut portion; and a retaining piece fixed to the molding die or formed so as to be integrated with the molding die, which retaining piece slidably retains the sliding piece. In demolding the molded product, the sliding piece moves in the direction in which the undercut portion can be demolded, by moving the holder in the demolding direction of the molded product.
