CASTING METHOD OF MOLTEN METAL AND CASTING MOLD USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new casting method enabling directional solidification while increasing cooling speed of a solidification process. SOLUTION: The casting method includes a melt supply step for supplying a metal melt I' to a cavity of a collapsible mold D which can be collapsed and a solidification collapse step for achieving the directional solidification of the metal melt I' by directly cooling it through sequential collapse of the collapsible mold D holding the metal melt I' in the cavity. When the collapsible mold D is a water collapsible sand mold D which is collapsed by absorbing water, the metal melt I' is directly cooled by water together with the collapse of the water collapsible sand mold D through injection of water to the water collapsible sand mold D, so that the solidification of the metal melt I' is accelerated.
