A kind of soft water circulating water cooling mold device for edge milling wheel

Abstract

A soft water circulating water-cooling mold device for edge-milled wheels comprises annular water mist cooling pipes, water mist generators, a cooling water treatment tank, a cooling water storage tank and a soft water storage tank. Annular U-shaped grooves which are 10.0-12.0 mm deep and 12.0-15.0 mm wide are milled in larger casting wall thickness parts of a top mold and a bottom mold, the annular water mist cooling pipes are inlaid in the grooves, soft water enters water vapor mixing chambers of the water mist generators via water pipe joints under the action of compressed air, and water vapor mixtures are further atomized by conical water mist nozzles, enter water mist outlet joints, enter water mist flow dividers by the aid of connecting pipes and then uniformly enter inner-layer pipes of the annular water mist cooling pipes for circulation by the aid of the water mist flow dividers; the annular water mist cooling pipes absorb heat emitted by molds, water mist is converted into water vapor, and the water vapor carries heat to enter water vapor outlet pipes. The device is high in cooling effect, uniform in cooling and capable of preventing the molds from corroding.

Description

technical field [0001] The invention relates to the field of casting aluminum alloy wheels for automobiles, in particular to a soft water circulating water-cooling mold device for edge milling wheels. Background technique [0002] In recent years, with the continuous improvement of European and American consumers' requirements for the individualization and fashion of automobile wheels, as one of the key components of automobile drive systems, aluminum alloy wheels not only require reliable, stable safety and comfort. Moreover, the requirements for the appearance of aluminum alloy wheels are getting higher and higher, and some areas even raise the appearance of aluminum wheels to the perspective of artworks. In order to meet the needs of consumers, a variety of stylish aluminum wheels have appeared on the market, such as: fine car bright surface, bright edge spray color, milling wheel, etc. The emergence of these new varieties makes the wheel more and more popular. Important...

AI Technical Summary

Problems solved by technology

The former two have done a good job in the industry, but to achieve rapid solidification and increase the degree of crystallization supercooling during solidification, it is basically solved by designing air-cooling and water-cooling methods on the mold, but the improvement effect on pinholes is not good.

Air cooling not only requires the use of high-power air compressors to cause huge energy consumption, but also has a long casting cycle and poor cooling effect; although the cooling effect of water cooling is better than that of air cooling, the existing method has uneven cooling and water is directly sprayed on the mold Severe corrosion of the mold and abnormal phenomenon such as blockage of the cooling water pipe due to the formation of scale during use, resulting in unstable and unsmooth production. Therefore, how to develop a mold that can achieve rapid solidification, uniform cooling, and prevent severe mold corrosion and water pipe blockage It is necessary to solve the manufacturing bottleneck of milling wheels with a device
