Correct use and protection methods of precision die-casting molds: try to reduce the rapid cooling and heating of the mold, try to produce continuously, and prohibit high-speed injection under the condition of cold mold. During the precision die-casting process, the precision die-casting mold has always been in a reciprocating fatigue state of thermal expansion and contraction. The temperature of the mold cavity basically always changes back and forth between 160 degrees and 350 degrees. Tired and damaged.

When starting production under the condition of cold mold, the temperature of the mold rises from the low temperature, the temperature difference increases, the expansion of the mold increases, and the fatigue of the mold increases accordingly, which will accelerate the damage of the mold and shorten the life of the mold. Therefore, in the production of precision die casting, continuous production should be made as much as possible, the rapid cooling and heating of the mold should be reduced as much as possible, and then the life of the mold should be extended.
Reduce the injection speed as much as possible, reduce the specific pressure as much as possible, and reduce the impact of the mold. During the production of precision die casting, the unevenness of the injection speed not only affects the filling speed and the injection gate speed of the precision die casting, but also increases the impact peak when the injection speed is high. Therefore, if the injection speed is high and the injection gate speed is fast, the scouring of the mold will increase, the impact peak will increase, the impact force received by the mold will also increase, and the life of the mold will be greatly reduced.
