Cooling water channel embedded in hub mold and manufacturing method of cooling water channel

Abstract

A cooling water channel embedded in a hub mold comprises an annular groove formed in a matrix, a semicircular lower groove is formed in the bottom of the annular groove, an annular partition plate is embedded in the annular groove, a semicircular upper groove is formed in the bottom surface of the annular partition plate, the semicircular upper groove and the semicircular lower groove are oppositely closed to form the cooling water channel, an annular cover plate is embedded in the upper surface of the annular partition plate and is flush with the upper end of the annular groove, the inner edge opening and the outer edge opening of the annular cover plate are fixedly welded to the inner edge opening and the outer edge opening of the upper end of the annular groove respectively, the annular partition plate is pressed in the annular groove through the annular cover plate, cooling water and the annular cover plate are completely separated through the annular partition plate, in the using process, the cooling water cannot impact the annular cover plate, and the influence of the cooling water on the welding seam part can be greatly reduced. The welding technology of the cooling water channel structure is reasonably improved, so that the performance of the welding seam part is more stable. The hub mold manufactured through the method can delay cracking of the cooling water channel, and the service life of the mold is prolonged.

Description

technical field [0001] The invention belongs to the technical field of wheel hub molds, and in particular relates to a cooling water channel embedded in a wheel hub mold and a manufacturing method thereof. Background technique [0002] In order to reduce the production cost of aluminum alloy wheels, stabilize the casting process, improve product quality, and ensure the safety performance of the wheels, multiple cooling water channels are usually buried inside the wheel mold, and pure water with constant temperature and pressure is injected and then discharged to take away the wheels. The heat of the mold reduces the overall temperature of the product and the mold to meet the needs of the casting process. Hub molds usually include upper mold, lower mold and side molds. According to the design requirements, cooling channels can be buried in the upper mold, lower mold and side molds. Therefore, relatively speaking, the upper mold, lower mold and side molds can all be used as co...

AI Technical Summary

Problems solved by technology

In the prior art, due to the unreasonable structural design and welding process, the welding seam of the cooling water channel is often its weak point. Once it cracks, it will inevitably cause production stoppage, process disorder and other adverse effects, reducing work efficiency and increasing repair costs. It is also easy to lead to early scrapping of the mold
