摘要

A mold for molding a rear side of a refrigerator door is provided to prevent the secession of a gasket installed on the rear side of the door. A mold for molding a rear side of a refrigerator door comprises a corner undercut part. The corner undercut part forms a corner part in which an edge undercut part meets reciprocally to form an undercut part(2a) on the whole edge of a door rear side(2) to insert and fix a gasket. The corner undercut part comprises a corner block(41) moving forward and backward at the corner part one side of a mold body(10). The corner block has a corner block driving part(51). The corner block driving part makes the corner block reverse in the tack-up of the undercut and makes the corner block return to the front in the completion of the undercut tack-up. The corner block driving part is consisting of a cylinder body(511) and a cylinder rod(512). The cylinder body is fixed to the mold body. The cylinder rod is combined in the back-end of the corner block to move back.
