AI Technical Summary

Technical Problem

The existing cooling channel design of aluminum alloy wheel casting molds fails to provide a uniform temperature field, resulting in easy cracking and water leakage of welds, as well as high processing efficiency and low cost.

Method used

The design combines welding and perforation channels, along with an arc-shaped base and inclined installation. By combining the welding and perforation channels, a straight-hole channel is formed. Sealing covers and plugs are installed inside the channel. When used in conjunction with the casting mold, a uniform temperature field distribution is achieved.

Benefits of technology

It improves the uniformity of the mold temperature field, reduces the risk of water leakage in the weld, improves processing efficiency and reduces costs, and achieves effective cooling of aluminum alloy wheel blanks.

Abstract

This utility model belongs to the field of wheel hub casting, specifically relating to a cooling water tray and a casting mold, including a water pipe and a water tray base; the water tray base is provided with welding area water channels and perforated area water channels inside, the inner edge of the cooling water tray is arc-shaped, the perforated area water channels are connected to the water pipes outside, the cooling water tray is fixed at a 33° angle to the side mold of the casting mold, and the water channels are made by drilling straight holes on both sides and welding in the middle, which reduces the length of the weld seam; by the different distances of the water channels from the surface and the 33° angled installation method, the cooling water in the water channels carries away heat from the corresponding positions differently, thus uniformly heating the mold.
