high pressure aluminum casting.These issues with aluminum alloy die-casting molds

　　Aluminum alloy die-casting molds are necessary tools for producing aluminum alloy die-casting parts, and the cost of these tools is very high. A regular aluminum alloy die-casting mold costs tens of thousands of pieces, and the high cost requires good maintenance. In order to better use aluminum alloy die-casting molds, this article summarizes some issues that need to be paid attention to during the use of aluminum alloy die-casting molds for everyone.

　　1. Due to the high melting point of aluminum alloy, aluminum alloy die-casting molds are prone to high temperatures during the die-casting production process, requiring an additional cooling system, which is very helpful for the continuous use of the mold.

　　2. Because aluminum alloy contains a certain amount of iron, it is easy to stick to the mold during die casting. Therefore, it is necessary to spray a certain amount of release agent in the cavity of the aluminum alloy die casting mold. However, improper spraying of release agent can cause significant damage to the die casting mold, and attention should be paid during the production process.

　　3. Poor heat treatment of aluminum alloy die casting molds is a common problem, which can reduce the hardness of the die casting molds. However, if the hardness is generally not less than HRC-47, there will be no problem.
