After the press-fitting is completed, the drag plate 172 is pulled away from the mold frame 181. The center of gravity of the core skeleton 3 moves forward due to the pressing of the pin 2. When the drag plate 172 is away from the mold frame 181, the core skeleton 3 tilts forward and breaks away from the limit block 173. The core skeleton 3 falls into the material channel 15 from the discharge port 161, and the pressed core skeleton 3 is taken out from the material channel 15.
