摘要： PROBLEM TO BE SOLVED: To provide a casting structure capable of advantageously casting a molding die containing a convex part for improving cooling efficiency in a flow channel of a cooling medium.SOLUTION: A composite type structure includes a lost model and a sand mold which are combined for casting a molding die. The sand mold includes a convex form for forming a flow channel of a cooling medium in the molding die by removing the sand mold after casting, and the convex form of the sand mold includes a concave part for increasing a surface area of the flow channel. By engaging the sand mold and the lost model with each other, the concave part is sealed, and in this way, the composite type structure is constituted.

摘要： PROBLEM TO BE SOLVED: To provide a molding structure of high degree of design versatility, which can efficiently and inexpensively cast a thin-walled and large-sized product, for example, a component for a large diesel engine, and to provide a mold and a casting method using the structure.SOLUTION: In the composite structure with a lost foam pattern 2 and a core 3 being combined with each other, the contour of the lost foam pattern 2 is substantially the same as the contour of a cast product, and the lost foam pattern has at least two-split structure. The core 3 has a substantially the same shape as a hollow part of the cast product, and the core 3 is held by the lost foam pattern 2.
