Abstract

PURPOSE:To easily mold a composite core for casting of high accuracy capable of casting plural space parts simultaneously by integrally forming the foaming resin formed body formed in the specified shape in advance and the sand core molded from a sand and binder material. CONSTITUTION:The foaming resin formed body formed in the same shape as the partition part partitioning the space part of a casting is arranged at the specified position inside the mold for molding a sand core, in advance. Then inside this mold the molding material consisting of a sand and coking material is filled up and hardened to mold the sand core, and the sand core and foaming resin formed body are integrated. The composite core 1 consisting of the sand core part 2 and foaming resin formed body part 3 thus obtd. is arranged at the specified position of the inside of a casting main mold 4. A casting molten metal is then poured into this main mold 1. The molten metal is rounded to a space part 5 and filled up, also rounded to the foaming resin formed part 3 melted or burnt out by the heat of the molten metal. The casting product 6 having the space parts 6b, 6c partitioned by a partition part 6a is thus obtd.
