FULL-MOLD CASTING METHOD AND MOLD FOR USE IN THE CASTING METHOD

PROBLEM TO BE SOLVED: To provide a full-mold casting method by which a forward phenomenon does not occur while utilizing suction in the full-mode casting method, and also the defect of a casting product caused by gas generated from a lost foam pattern is prevented. SOLUTION: The full-mold casting method is provided in which a mold obtained by burying a lost foam pattern into casting sand packed into a flask is sealed, thereafter, a molten metal is poured therein, and a casting product is cast while vanishing the lost foam pattern by the molten metal, wherein the prescribed number of suction members independent on each other are arranged at the lower part, side parts and upper part of the flask around the lost foam pattern. The method includes: a step where, upon the start of molten metal pouring, suction is performed using the suction member at the lower part of the flask; and a step where the suction is changed to the suction members at the side parts of the flask and the suction members at the upper part successively in accordance with the raise of the molten metal surface.
