PURPOSE:To promote the directional solidification by blowing coolant to a die part corresponding to solidification starting part of product by a coolant supplying means arranged in a supporting plate. CONSTITUTION:In case of taking out the product 24 from the upper die 11, the upper take-out cylinder rod 20 is raised to raise a knock out pin 19 and the upper die 11 is further raised from the time, when the upper end face is hit to the lower face of the upper part fixed platen 21. Compressed stress acts on the supporting plate 13, connecting rod 15, push-out plate 17 and knock out pin 19, and when it is exceeded to the shrinkage force between the product 24 and the upper die 11, the product is taken out from the die. Before taking out the product 24 from the die, compressed air is supplied to cooling pipe 23, to directly cool the surface of upper die 11 and also make the die clean. After that, again die clamp for next casting is executed.
