Description

Technical Field

[0001] The utility model relates to the technical field of mold cooling, in particular to a multi-stage cooling device for an aluminum alloy pressure casting mold. Background Art

[0002] Aluminum alloy is a lightweight, high-strength material with good thermal conductivity and corrosion resistance. In die-casting molds, aluminum alloy is mainly used to manufacture the mold shell, mold base and other parts. Die casting molds refer to the metal molds used to form castings in the die casting molding process. The mold needs to be cooled after die casting.

[0003] The existing device mainly cools the mold by water cooling or air cooling. The existing technology is similar to a multi-stage cooling device for aluminum alloy wheel hub casting mold. The structure with patent number CN111001783B includes a water tank, a placement tank, a base, a lower mold, an upper mold, an air outlet, an air outlet pipe, a lifting plate, a limit device, and a hydraulic rod. In the cooling process, the heat dissipation efficiency is greatly improved, and the molding speed is increased. The cooling device has a simple structure and is easy to operate and use, but the device still has areas that can be optimized.

[0004] The existing device mainly absorbs the heat of the mold through the coolant inside the water tank, which makes it difficult for some devices to gradually sink the mold into the water tank, causing a large amount of coolant inside the water tank to evaporate. At the same time, some devices mainly place the mold above the lifting frame, making it difficult for some devices to drive the mold away from the top of the water tank, which makes it easy to load and unload the mold and place it on the push plate, reducing the convenience and practicality of the device. Therefore, in order to solve the above problems, a multi-stage cooling device for aluminum alloy pressure casting mold is proposed. Utility Model Content
