Title: UNDERCUT TREATMENT MECHANISM, MOLDING DIE AND MOLDED ARTICLE
Abstract:
The present invention provides: an undercut treatment mechanism which can be designed to have a compact and simple configuration while enabling easy stripping of an undercut part; a molding die; and a molded article. Provided is an undercut treatment mechanism 10 which is used by being mounted to a molding die 1 for molding a molded article P having an undercut part P1 and which enables stripping of an undercut part P1 that protrudes in a direction intersecting with the stripping direction of the molded article P, the undercut treatment mechanism being provided with: a holder 20 which is fixed to or integrally formed with the molding die 1; a slide piece 30 which has a molding part 32 for molding the undercut part P1 and which is capable of sliding with respect to the holder 20 so as to cause the molding part 32 to come off the undercut part P1; a holding piece 50 which is capable of advancing or retreating with respect to the holder 20 in a direction intersecting with the stripping direction of the molded article P and which slidably holds the slide piece 30; and an angular pin 12 which causes the holding piece 50 to advance or retreat.
