[0002] Die-casting molds are very expensive due to their high manufacturing precision, large investment and long production cycle. Each die-casting mold manufacturer hopes to take effective measures to extend the service life of the die-casting mold. However, due to a series of internal and external factors, such as the influence of machining and materials, these influencing factors directly lead to the premature failure and scrapping of the die-casting mold, causing great waste. After the casting alloy is melted, it enters the mold cavity through the pouring system. In the process of injecting the molten metal into the mold cavity, due to the fluidity and filling effect of the molten metal, the molten metal forms a continuous streamline structure in the mold cavity, thereby forming cavities and pits of a certain shape. At the same time, due to the filling effect of the molten metal, the cavity gradually expands and fills the entire cavity, and after cooling, it forms automotive metal parts.
