PURPOSE:To compact construction of a device by arranging each fitting plate as shiftable toward axial direction in a pull-out cores having different fitting angles respectively and connecting both fitting plates by link mechanism. CONSTITUTION:Pull-out pins 11, 12 are arranged in guide holes in upper die 7 as the pull-out cores 11, 12. The fitting plates 13, 15 are respectively jointed as crossingly at upper end of each pin 11, 12 and both near end parts of the fitting plates 13, 15 are connected by one pair of the links 16, 16. Further, guide pins 19, 20 are planted on the die 7 as the same inclination as the pins 11, 12 to make the fitting plates 13, 15 slidably through bushes 21, 22. After casting, at the time of ascending the fitting plate 13 by a cylinder 14, the pin 11 is pulled out from the product and also the pin 12 is pulled out through action of the link 16. As the fitting plates 13, 15 are connected by link mechanism, the constructure is simplified and only one of driving source can be pulled out to the all pull-out cores. Therefore, the whole apparatus is compacted.
