Abstract

The invention provides a differential pressure casting machine and a casting method. The differential pressure casting machine comprises a base plate. A fixed mold plate mechanism is arranged at the upper end of the base plate. A lower mold and a lower mold cover are arranged in the middle of the upper end of the base plate, and the lower mold cover covers the outer side of the lower mold. An upper mold and an upper mold cover are correspondingly arranged exactly above the lower mold and the lower mold cover, and the upper mold cover covers the outer side of the upper mold. The upper mold and the upper mold cover are connected with a moving mold mechanism through a moving mold plate, and the moving mold mechanism is connected with the fixed mold plate mechanism and moves up and down along the fixed mold plate mechanism. A holding furnace is arranged at the bottom of the base plate, and comprises a holding furnace driving mechanism. The holding furnace driving mechanism is connected with the base plate through a support. A liquid ascending pipe is located below the base plate and connected with the holding furnace. By the adoption of the differential pressure casting machine and the casting method, the optimal mold filling speed can be obtained, top-quality mold-filling molten metal can be obtained, external inclusion can be prevented from entering the differential pressure casting machine, and castings which are dense in organization and excellent in performance, and have few casting defects can be obtained.

Description

technical field [0001] The invention relates to the technical field of metal casting equipment, in particular to an aluminum alloy differential pressure casting device and method. Background technique [0002] At present, the aluminum alloy casting equipment commonly used in our daily production includes low-pressure casting machines, gravity casting machines, and high-pressure casting machines. Thin-walled aluminum alloy castings. Differential pressure casting is a casting process method of filling under pressure and solidification and crystallization. This process combines "controllable speed filling" and "pressure crystallization" to obtain the best filling speed and the highest quality filling The molten metal endows the product with a structure and performance different from that of metal mold casting and low-pressure casting products. Contents of the invention [0003] The purpose of the present invention is to provide a differential pressure casting machine and a ...
