Casting equipment and casting method thereof

Abstract

The invention belongs to the technical field of casting production and provides casting equipment. The casting equipment comprises a crucible melt pool, a casting box, a furnace cover lifting mechanism and a mold moving mechanism. The crucible melt pool is arranged in the casting box, and comprises a casting liquid inlet and a casting liquid outlet. Both the casting liquid inlet and the casting liquid outlet extend out of the casting box, the furnace cover lifting mechanism and the mold moving mechanism are both installed at the upper end of the casting box, the furnace cover lifting mechanismis arranged above the casting liquid inlet, the furnace cover lifting mechanism is connected with a gas control device, the mold moving mechanism is movably arranged at the upper end of the casting liquid outlet, and the mold moving mechanism is connected with a vacuumizing device. According to the equipment, molten metal in the crucible melt pool is squeezed into the mold moving mechanism for casting by introducing air pressure into the casting liquid inlet, a traditional low-pressure casting liquid lifting pipe is omitted, and the equipment has the advantages of being high in generation efficiency, low in production cost and high in casting production quality.

Description

technical field [0001] The invention belongs to the technical field of casting production, and in particular relates to a casting equipment and a casting method thereof. Background technique [0002] Low-pressure casting is the main forming process in the aluminum alloy manufacturing industry. The traditional low-pressure casting process is to pressurize the dry gas in the holding furnace, and through a liquid riser connecting the mold and the molten aluminum in the furnace, the liquid passes through the riser under the gas pressure. The liquid pipe enters the mold cavity to obtain the casting. However, in the field of ferrous metals, the casting temperature is high, the material consumption of the riser is large, and the sealing problem is difficult to deal with when replacing, resulting in low production efficiency and high cost, which cannot be used in large-scale production; and after the casting is completed, stop pressurizing the heat preservation furnace After the pr...
