Abstract

PURPOSE: To eliminate gas leakage and to improve working environment by molding a master mold with split patterns by the use of molding sand contg. a gas hardenable binder.
CONSTITUTION: A lower flask 4 and a lower pattern part 5 are placed on the top surface of a pattern base 1 provided with an evacuating chamber in the inside and plural vent holes 3 communicating with the chamber 2 on the top surface, and molding sand 6 contg. a gas hardenable binder is packed in the space delineated by the base 1, the part 5 and the flask 4. The top of the flask 4 is then covered with a cover member 22, and a gas generator 11 is communicated with a gas supply port 10. After the inside of the chamber 2 is evacuated, the hardening gas of the generator 11 is passed through the inside of the sand 6, thereby hardening the sand. The member 22 is then removed, the flask 4 incorporating the molded lower mold is turned over upside down and is relocated on the top surface of the base 1, and an upper pattern part 15 is registered to the rear surface of the part 5. Molding sand 17 is then hardened in the part 15 by the same method as that mentioned above, whereby the master mold is molded.
