[0002] Both V-method casting and lost foam casting use vacuum forming, but there are significant differences in their process flows. The biggest advantage of V-method casting over traditional sand casting is that it does not use adhesives. V-method casting uses plastic film to seal the sand box, and relies on a vacuum exhaust system to extract the air in the mold. There is a pressure difference between the inside and outside of the mold, which makes the dry sand dense and forms the required cavity. After core setting, box closing, and pouring, the casting is vacuumed to solidify and the negative pressure is released. The molding sand then collapses to obtain the casting. When the casting is cast using the V-method casting process, a large amount of dust is generated, and a dust removal device is required. Therefore, a vacuum system dust removal device for V-method casting is urgently needed.
