[0002] Die casting mold is a tool for casting metal parts; the basic structure of die casting mold includes upper die base, lower die base, upper mold plate, lower mold plate and ejector rod. In the die casting process, the molten metal is first injected into the mold cavity, and the mold cavity surface is pressurized and forged as the molten metal cools; the cooling system is an important part of the die casting mold, which is directly related to the cooling rate and temperature distribution of the casting.

The die-casting mold cooling structure has low maintenance costs and is easy to promote and use.

[0004] Although the die-casting mold cooling structure has the advantage of low maintenance cost, the device still has the following problems when cooling the mold: the device only cools the mold through a cooling component, and the cooling component is arranged in a cooling hole. The contact area between the cooling component and the mold is small. When water flows in the cooling component, it can only take away a small amount of heat in the mold. Therefore, the heat dissipation effect of the cooling component of the device is not ideal, and the heat dissipation efficiency is low. In view of this, we propose a cooling mechanism for a die-casting mold. Utility Model Content
