Die-casting die circulation cooling system

Abstract

The invention discloses a die-casting die circulation cooling system, comprising a die-casting die, a cooling water tower, a water supplying pipeline and a water returning pipelines; a plurality of cooling water channels are formed in the die-casting die; the water inlet ends of the cooling water channels are provided with a plurality of water inlet pipes; the water outlet ends of the cooling water channels are provided with a plurality of water outlet pipes corresponding to the water inlet pipes respectively; the water supplying pipeline is connected between a water supply end port and the tail ends of the water inlet pipes; the water returning pipeline is connected between a water returning end port of the cooling water tower and the tail ends of the water outlet pipes. The die-casting die circulation cooling system also comprises infrared die temperature measuring equipment. Through the mode, the die-casting die circulation cooling system specifically performs flow regulation on each cooling water loop, thus improving the pertinence and balance of die temperature control, improving product quality and greatly prolonging the service life of a die-casting die.

Description

technical field [0001] The invention relates to the field of die-casting production of automobile parts, in particular to a circulating cooling system for a die-casting mold. Background technique [0002] In die casting production, the mold temperature is very important to the internal quality and appearance of the formed product, mainly affecting the internal air shrinkage cavity, shrinkage porosity and appearance of the casting as ablation sticking aluminum and cold shut. At present, the mold cooling method commonly used in China is direct cooling or centralized point cooling. This control method cannot balance the mold temperature well, and it is not easy to control the mold temperature within the range of process requirements. This will not only affect the internal and external appearance of the product. , and the fluctuation of mold temperature will also cause unstable product quality. After the overheated core sticks to aluminum, it will cause the deviation of product ...

At present, the mold cooling method commonly used in China is direct cooling or centralized point cooling. This control method cannot balance the mold temperature well, and it is not easy to control the mold temperature within the range of process requirements. This will not only affect the internal and external appearance of the product. , and the fluctuation of mold temperature will also cause unstable product quality. After the overheated core sticks to aluminum, it will cause the deviation of product size and reduce the life of the mold.

[0003] For the part of the local heat junction on the mold, conventional cooling methods often cannot effectively cool down the temperature. At this time, most die-casting companies use external spraying to cool the mold, which makes the production cycle time of the product longer and the production efficiency lower.
