Abstract
A casting device of a large non-ferrous metal thin-walled structural component. A liquid outlet of the casting device is communicated with a casting sand box. The casting device comprises an L-shaped liquid storage cylinder, a pressure supplying cylinder, and a crystallization treater. Protective gas with the first gas pressure can be inflated into the top of the L-shaped liquid storage cylinder. The pressure supplying cylinder and the L-shaped liquid storage cylinder are integrally connected to form a U-shaped tube connector. Protective gas with the second gas pressure can be inflated into the top of the pressure supplying cylinder. A liquid inlet of the crystallization treater is communicated with the pressure supplying cylinder while a liquid outlet is communicated with the pouring system and the mold cavity. The crystallization treater is provided with a grain refining mechanism.
