Abstract
PURPOSE: To enable the achievement of the intended object even if heat-insulating molding damages by enclosing the entire circumference of the barrel-form heat- insulating molding by metal body.
CONSTITUTION: The captioned casting to be used for the exhaust pipe of an internal combustion engine or the like is formed by inclosing the entire circumference of the heat-insulating molding 11 formed into barrel form by molding sand such as CO2 molding sand or ceramics with a metal body 12. Suitable curved faces are provided to both ends of the molding 11 and the metal body 2 is formed by castable metal such as cast iron. To form this heat-insulating structure casting, the cavity 16 conforming to the size of the said casting is formed by the main mold 14 by molding sand and core 15 in, for example, a molding flask 13, and the molding 11 is disposed at its center. For this, a core-suppouting jig 17 is interposed between the side face of the core 15 and the molding 11 and between the main lmold 14 bottom and molding 11. In this case, the jig 17 is of the same material as that of the metal body 12 and the molten metal of the metal body 12 is poured into the spacing thus formed through a sprue 18, whereby the foregoing casting is obtained.
