How to cool the gas mold temperature machine during die casting?
announcer:
First of all, for the cooling of the die-casting mold of the gas mold temperature machine, we actually can directly use the heat pipe cooling method. In this respect, it is mainly used for small parts that are difficult to cool directly with cooling water. For the small parts of the gas mold temperature machine that need to be cooled, we actually should use the special heat of the heat pipe for export, and then use the cooling water to cool the heat pipe.

     Next, regarding the cooling method of the gas mold temperature machine, we actually should pay attention to the indirect cooling method. In this respect, in the hot joint of the die-casting mold of the mold temperature machine, in fact, it can directly use an alloy with high heat transfer coefficient (ammonium bronze, tungsten-based alloy, etc.) for indirect cooling. At that time, we can actually screw the ammonium bronze pin into the fixed core. For the end of the copper pin, there will actually be a heat sink to enhance its cooling effect.

    Another cooling method for the gas mold temperature machine is water cooling. A cooling water channel is directly provided on the die-casting mold. In this respect, it can actually pass the circulating water to the forming insert or the core to a large extent.

    In this respect, the water-cooling cooling efficiency is relatively high, which can effectively reduce the temperature on the surface of the cavity, but in terms of another aspect, it actually increases to a large extent. The complexity of the die-casting structure is mainly used for molds that require relatively large heat dissipation.

    In terms of the cooling method on the gas mold temperature machine, it is actually to prevent the phenomenon of condensation on the surface of the cavity. For the temperature of the cooling water, it should be directly above the room temperature. In fact, the cooling on the gas mold temperature machine can actually adopt the method of air cooling, and the cooling temperature of the air cooling is actually directly less than the method of water cooling.
