Abstract
A casting mold includes a cavity for molding a product, and a pouring basin and a passageway that guide molten metal into the cavity. The passageway includes, at portions thereof positioned below the pouring basin and the cavity, bent portions (a first bent portion, a second bent portion) that change the advancing direction of the molten metal, and the casting mold further includes a cover member, which covers the inner wall of the bent portion, allows the passageway positioned on the upstream side of the bent portion to communicate with the passageway positioned on the downstream side of the bent portion, and has a lower thermal conductivity than the base material of the mold.
