PROBLEM TO BE SOLVED: To automatically produce a molded product having an undercut part by a small-sized simple structure. SOLUTION: A receiving plate 14 is moved toward an intermediate plate 18 when a movable mold 3 is opened with respect to a fixed mold 2 and a center slide core 13 is separated from a pair of side slide cores 17 while the respective side slide cores 17 are pressed into cores 16 to be separated from an undercut part. Further, the intermediate plate 18 is drawn by the receiving plate 14 to be integrated with a movable retainer plate 20 to be moved from a fixed retainer plate 5. Thereafter, the intermediate plate 18 is moved to the movable retainer plate 20 reaching a stroke end to separate a pair of the cores 16 and a pair of the side slide cores 17 with respect to the molded product left on the movable retainer plate 20.
