PROBLEM TO BE SOLVED: To provide a mold for a molded article capable of molding a high quality molded article wherein the structure of the mold is simplified and downsized, and at the same time, the workability during maintenance work is improved. SOLUTION: The mold for molded article comprises a fixed mold 2 which molds the outer face of a main body part 21 of the molded article 20 and a part of the outer face of an undercut part 22, and a second molding mold 3 comprising a slide core 11 which molds the rest of the outer face of the undercut part 22, a slanted core 12 which molds the inner face of the undercut part 22 and a part of the inner face of the main body part 21, and a movable mold 13 which molds the rest of the inner face of the main body part 21. The slide core 11 and the slanted core 12 are disposed on a ejector plate 4. While the undercut part 22 of the molded article 20 is held by the slide core 11 and the slanted core 12, the whole is capable of moving in such a direction as the undercut part 22 is released from the fixed mold 2 and the undercut part is capable of independently moving in such a direction as the undercut part 22 is released from the slanted core 12.
