Abstract

PURPOSE: To make rapping after molding of the metal mold easy by beforehand forming a low-melting-point metal layer on the metal sprayed surface of a wooden pattern by spraying then forming an iron oxide red layer thereon at the time of manufacturing the metal mold by metal spraying.
CONSTITUTION: Sn is sprayed as under-treatment for removing of the spraying material for metal mold forming on the portion, which becomes the metal mold surface to undergo metal spraying, out of a wooden pattern molding board 1 and the wooden pattern 2 mounted thereon and a Sn layer 3 of about 0.05W0.5mm thick is formed thereon. Further the mixed liquid of iron oxide red and binder is spray-coated thereon to form an iron oxide red layer 4 of about 0.05W0.3mm thick. Next, a molding flask 5 is placed on the molding board 1, and spraying material for metal mold forming is sprayed to about 2W10mm thick on the under-treated pattern 2 and molding board 1, whereby a metal mold shell layer 6 is formed and is then reinforced by cast iron 7. The foregoing under-treatment obviates the entry of the spraying material for metal mold forming into the wooden pattern surface and enables the easy parting of the wooden pattern.
