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 demolding of the undercut portion. The undercut processing mechanism includes: a holder attached to or formed integrally with the molding die; a sliding piece configured to be slidable relative to the holder such that a mold core is moved so as to demold the undercut portion; a retaining piece configured to retain the sliding piece such that the sliding piece is slidable; and a support wall configured to support the sliding piece so as to prevent the sliding piece from being tilted when the sliding piece slides. The sliding piece forms a part of the mold core for forming the undercut portion.
