Title: Manufacture of casting
Inventor: MIYAZAWA NOBUO
IPC: B22C9/12
Filed: 1988-02-18
Abstract: PURPOSE:To prevent the generation of a harmful gas and the formation of a defective casting by sublimating the following pattern by a microwave prior to pouring a molten metal in manufacturing a casting by using the mold pattern made of a foaming styrene coated with a die coating agent on the outer wall face. CONSTITUTION:The mold pattern made of a foaming styrene coated with a die coating agent on the outer wall face is imbedded in the mold and sublimated by a microwave heating. A molten metal is poured into the hollow mold with the die coating film thus formed as the inner wall. When the microwave is hit on the film of the die coating agent coated on the outer wall face of the mold pattern made of a foaming styrene, the film is preferentially heated with good efficiency, so the pattern is sublimated by being decomposed in a short time. Consequently, no casting defect is brought about with the generation of a formaldehyde gas accompanied by the imcomplete combustion of a polysty rene and residue of one part attaining to a carbide.
