PROBLEM TO BE SOLVED: To provide a sliding mold system for injection molding which has a cooling mechanism exerting a sufficient cooling effect in a slide mechanism with dense components. SOLUTION: There is provided the sliding mold system for performing the undercut molding of a molded article by reciprocating a slide member (112) which composes a part of a cavity (126). The system has a cooling channel (200a) disposed inside the slide member, a degassing hole (200b) communicating the inside of the cooling channel with that of the cavity, a sucking means (204) for sucking the gas in the cooling channel, and the means (202, 206) for communicating or shutting off the inside and outside of the cooling channel.
