Abstract: A static casting method for a hollow cast product using a mold with bottom comprising a top lid, a core and an outer mold section, the core being attached to the top lid and disposed inside the outer mold section. The outer mold section includes a lateral mold section and a lower mold section. The lateral mold section is formed at its inner peripheral wall portion with a composite cooling section by stacking chiller blocks and interposing therebetween refractory sands and at its outer wall portion with refractory sands. Cooling pipes include first and second pipes. A first pipe extends longitudinally through the refractory sands at the outer wall portion and a second pipe extends longitudinally through the inner wall portion in contact with at least a part of each of the chiller blocks, the first and second pipes being connected at their lower portions through the bend portion. The chiller blocks are cooled by water flowing in the second pipes. The entire casting cavity is first filled with molten metal. Then cooling water is passed through the cooling pipes until solidification of the metal is complete. Thereafter the supply of water is stopped and water remaining in the pipes is discharged.
