Abstract

The invention discloses an aluminum wheel low-pressure casting water cooling die. A center die insert 8 is provided with a water cooling channel 9 for cooling the wheel center; a water cooling channel 7 for cooling the inner rim is arranged at the upper part of a head die 5; a lower edge die 2 is provided with a water cooling passage 3 for cooling a wheel hot spot. The casting technology mainly includes a slow-to-quick mold filling technology and a water-to-air cooling technology. According to the invention, the performance quality of the aluminum alloy wheel casting is improved, and the performance quality of the casting is greatly improved in stability and consistency due to the adoption of the slow-to-quick mold filling technology and the water-to-air cooling technology; the high water cooling intensity increases the freezing rate of the casting, thereby increasing the casting production efficiency; cooling water flows in the water cooling channels relatively sealed, so that noise pollution caused by compressed air in the air cooling technology is eliminated, and the casting working condition is improved.

Description

technical field [0001] The invention relates to the field of aluminum alloy casting, in particular to a low-pressure casting mold and technology. Background technique [0002] At present, the low-pressure casting methods of aluminum alloy wheels at home and abroad include air-cooled cooling process and water-cooled cooling process. Due to reasons such as technology inheritance and process maturity, most domestic low-pressure casting air-cooled cooling processes are used. The traditional air-cooling process for low-pressure casting of aluminum wheel blanks is as follows: cooling air holes are drilled in the back cavity of the mold, compressed air is blown into the cooling air holes of the mold through stainless steel cooling air pipes, and the mold is cooled by convective heat exchange between the two. Cool down the corresponding position, so as to achieve the purpose of sequential solidification of aluminum wheels. However, this method uses compressed air to air-cool the c...
