  1,mold temperature affects the life of die casting mold

  When the mold material is in a tough state,the stress causes plastic deformation of the mold;and in the brittle state,the stress causes hot cracking and cracking of the mold.Periodic thermal stress causes the mold to thermally fatigue and crack.If the mold temperature is too high,the mold is easy to be deformed;in the continuous die-casting production process,once the die-casting is performed once,the mold temperature is cycled from high temperature to low temperature,and is continuously heated and cooled,and the inside of the mold generates thermal stress due to the temperature difference.

  2,the mold temperature affects the effect of the release agent

  When the mold temperature is too high,the release agent volatilizes excessively at a high temperature,and a dense film cannot be formed,which easily causes a sticking mold.When the mold temperature is too low,the film formed by the release agent contains non-volatile water,which makes the mold release effect poor,and also causes the porosity of the casting and the occurrence of cold partition defects;

  3,mold temperature affects the quality of die castings

  When the mold temperature exceeds a certain temperature,the mechanical properties of the die casting will be significantly reduced.
