Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem that a useful life of a composition for manufacturing a casting mold is shortened and formation of the casting mold is obstructed, when a self-hardening mold is used in summer and in the state that the temperature of sand is high (1), and/or is made by the sand having strong alkalinity (2). SOLUTION: The composition for manufacturing the casting mold contains a phenol resin, an isocyanate compound, an organic basic catalyst, an acid chloride of an acid substance of 1 to 10 pKa, and fireproof aggregates. The useful life and the hardening time of the composition for manufacturing the casting mold can be simultaneously adjusted as required by adjusting the quantity of the organic basic catalyst and the acid chloride of the acid substance of 1 to 10 pKa.
