PROBLEM TO BE SOLVED: To automatically produce a flanged elbow having an elbow becoming an undercut part by a small sized simple structure. SOLUTION: A movable retainer plate 18 is moved when a movable mold 3 is opened to separate the flanged elbow 100 from a fixed retainer plate 5 while a slide core 17 is slid along an angular pin 6 with respect to the movable retainer plate 18 to be separated from the elbow. After the completion of mold opening, a second ejection plate 24 is moved along with a first ejection plate 21 not only to release the flanged elbow from the movable retainer plate 18 through first ejection pins 201 and 202 and second ejection pins 221-223 but also to slide a floating core 14. Further, the second ejection plate 24 is moved to the first ejection plate 21 regulated through a stop bolt 9 and the flange opposite to the elbow side in the flanged elbow ejected through the second ejection pins 221-223 to revolve the floating core 14 to separate the elbow.
