1, die casting mold temperature affect life expectancy.
In continuous casting production process, every time die-casting mold temperature is once constantly being heating and cooling from a high temperature to low temperature cycle, internal mold thermal stress due to temperature. When the mold material is ductile state, stress mold plastic deformation; while in the brittle state, so that the mold thermal stress cracking, cracking. Cyclic thermal stress cause mold to thermal fatigue cracking. Mold temperature is too high, mold deformation;
2, mold temperature influence the effect of the release agent.
When the mold temperature is too high, release excess volatile at high temperatures, can not form a dense film, could easily lead to sticky mode. The film mold temperature is too low, the release agent is not volatile form containing water, so that the release of poor results, but also lead to casting porosity, cold shut defects;
3, die casting mold temperature affect quality.
When the die temperature exceeds 250 ℃, the mechanical properties of casting decreased significantly.
