The difference between the two cooling methods of die casting molds

Die casting mold is a commonly used equipment in the mold industry. It usually has two cooling systems. One is to use a mold temperature machine to cool, and the other is to cool directly with water. The two cooling systems have certain differences in the production and use of molds. A more suitable method should be selected according to its characteristics.

Under normal circumstances, for some precision and thin parts, a mold temperature machine can be used to cool, so that the mold will not be affected by the die-casting cycle time, causing the temperature to be unbalanced or too low, and to ensure that the mold is in Normal mold temperature; in some relatively large molds, the cooling method used is direct water cooling. In addition, the cooling medium used must be better than oil. The role of mold temperature is to ensure that the mold is die-casting The temperature should not be lower than the normal temperature of the mold, or lower than the temperature required for mold forming.

When using a mold temperature machine and direct water flow for cooling, the biggest difference is that the mold temperature machine uses high-temperature oil to heat the mold, while direct water cooling uses cooling water to cool the mold. The temperature is carried out at the end of the year. Although the final purpose is to keep the temperature of the mold within the required range, it will have a very large impact on the service life of the mold. Using a mold temperature machine to control the mold can make the mold last longer. The cooling water may reduce the service life of the mold.
