摘要： PROBLEM TO BE SOLVED: To provide a new casting method using unidirectional solidification.
SOLUTION: A molten metal M filled into a cavity 10c of a closed mold 1 is solidified from the bottom part of the cavity 10c by cooling the bottom face 11s of the cavity 10c. The casting method comprises: a cooling step where a cooling member 11 arranged inside the cavity 10c so as to be elevatable and partitioning the bottom face 11s is cooled; a pouring step where a molten metal M is poured from above the cavity 10c to the cavity; and a volume changing step where the position of the cooling member 11 cooled during the pouring step is moved to the lower part, and the volume of the cavity 10c is increased. By the casting method, a casting having high dimensional accuracy together with high internal quality can be produced. The obtained casting can be provided as it is without being subjected to working such as cutting when it is used for forging as the stock for forging or is used as a product.
