In order to prolong the service life of precision die casting die, timely cooling is more important when the temperature is high. Cooling methods for precision die casting include water cooling, air cooling, heat pipe cooling and indirect cooling. Let's have a look at it in detail.
To prolong the service life of precision die casting dies, it is more important to cool them in time when the temperature is high. The cooling methods of precision die casting dies include water cooling, air cooling, heat pipe cooling and indirect cooling. Let's take a closer look
1. Water cooling: precision die casting mold factory provides cooling water channel to make circulating water enter the molding insert or core, so as to bring heat out of the mold. The water cooling efficiency is high, which can effectively reduce the cavity surface temperature, but increases the structural complexity. It is mainly used for molds that need a lot of heat dissipation. To prevent condensation on the surface of the cavity, the temperature of the cooling water should be higher than the room temperature
2. Air cooling: For the parts in the die casting mold that are difficult to be cooled with water, air cooling can be adopted, and air cooling can be conducted by blower or compressed air. Air cooling can not only cool the precision die casting mold factory, but also blow the coating evenly, disperse the volatile gas of the coating, and reduce the porosity of the casting. The cooling temperature of air cooling is much lower than that of water cooling
3. Heat pipe cooling: mainly used for small parts that are difficult to be directly cooled with cooling water. In small parts requiring cooling, heat pipes are used to extract special heat, and then cooling water is used to cool the heat pipes
4. Indirect cooling: alloy with high heat transfer coefficient can be used for indirect cooling at the hot spot of the die casting mold of the mold temperature machine. The ammonium bronze pin is screwed into the fixed core, and the end of the copper pin is provided with a radiator to enhance the cooling effect
The above content is about the cooling method of precision die casting mold, and I hope it can help you better understand the die casting mold
