Abstract
PURPOSE: To substitute the air in a mold contained among sand particles and perform casting by enveloping the entire part of the mold with a bag of a gas impermeable film, and flowing an inert gas through the small holes in a sprue part and a riser part through the opening part of the bag.
CONSTITUTION: A bag 10 made of a film which prohibits permeation of gases is put on a mold 1 by leaving a clearance 13. The circumferences of a sprue part 5 and a riser part 6 are affixed to the film by means of a glue material 11. Further, a pouring bush 7 is affixed on the film above the part 5 and a riser mold 8 above the part 6 respectively by means of a a glue material 12 to provide sealing. Thence, small holes 15, 16 are provided in the film in the places of the sprue part and the riser part, respectively. The opening part 14 of the bag 10 is throttled and an inert gas is flowed into the bag 10 through a regulator 21 from an inert gas cylinder 20 at suitable pressure and flow rate and is flowed out through the holes 15, 16 to substitute the air in the mold. Thence, while the inert gas is kept flowed into the mold 1, casting work is carried out.
