A mold composed of two half-molds arranged to undergo pivotal movement into a mold closing position, for molding an article having a reentrant portion extending to both sides of the plane of closure of the half-molds, is also arranged so that during pivotal movement out of the mold closing position one of the half-molds undergoes translational movement parallel to the plane of closure in order to release the reentrant portion of the article from the mold cavity.
