Description

[0002] In the field of magnesium alloy die casting mould, the traditional die casting mould has a series of problems in demoulding and mould cooling, which seriously affects the efficiency, quality and cost of magnesium alloy die casting production.

[0003] Most of the traditional magnesium alloy die casting moulds rely on manual demoulding, and the manual demoulding speed is slow. After each die casting is completed, the worker needs to manually take out the formed magnesium alloy parts from the mould, which consumes a lot of time and leads to the inability of the die casting production to realize efficient continuous operation, greatly limiting the improvement of production efficiency. The quality of manual demoulding is unstable, and there are differences in the operation method and force of different workers. Even the same worker may have inconsistent operation after a long time of work, which is easy to cause deformation, strain and other defects of the product in the demoulding process, affects the stability of product quality, and increases the scrap rate.

In the use of the above-mentioned die casting mould, the magnesium alloy die casting mould relies on manual demoulding, which increases the labor intensity and safety risk of workers and limits the improvement of production efficiency. However, it still has other problems, such as slow mould cooling speed, which requires a long waiting time after each die casting for the mould to cool down to the appropriate working temperature before the next die casting, greatly prolonging the die casting cycle and reducing the production efficiency. Uneven cooling is common, which can cause inconsistent shrinkage of the magnesium alloy during solidification, resulting in deformation, shrinkage hole and other defects, affecting the dimensional accuracy and mechanical properties of the product. In the production of some magnesium alloy aviation parts with high requirements for dimensional accuracy, the product defects caused by uneven cooling make a large number of products unable to meet the qualified standards.
