Title: Method for supplying molding sand into molding machine and device there for
Inventor: ISSHIKI AKIHIRO
IPC: B22C5/18
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To improve the working environment by regulating the scattering of molding sand and fine powder to the min. limit, at the time of charging the molding sand from a sand charging means to a sand temporary storing means. SOLUTION: In the method for supplying the molding sand 2 into a molding machine from the sand temporary storing means after charging the molding sand 2 into the sand temporary storing means having an upper opening part from the sand charging means, the molding sand 2 is passed through a chute 3 having smaller width than that of the sand temporary storing means and charged into the sand temporary storing means. At the time of changing the sand, ascending current developed when the air in the sand temporary storing means escapes upward, is guided into the inside of the chute 3 and the ascending fine powder is introduced into the inside of the chute 3 so that only the air escapes from a gap with the chute 3.
