Die-casting mold is one of the three major elements of die-casting production. A mold with correct and reasonable structure is the premise for the smooth progress of die-casting production, and plays an important role in ensuring the quality of the casting (the pass rate of the lower machine).

Due to the characteristics of the die-casting process, the correct selection of process parameters is the decisive factor for obtaining high-quality castings, and the mold is the premise for the correct selection and adjustment of process parameters. Die design is essentially a comprehensive reflection of various factors that may occur in die casting production. The mold design is reasonable, the actual production problems are less, and the off-line qualification rate of castings is high. On the contrary, the mold design is unreasonable. Although the cavity finish of the fixed mold is very smooth, it still sticks to the fixed mold due to the deep cavity. Therefore, when designing a mold, it is necessary to fully analyze the structure of the casting, be familiar with the operation process of the die-casting machine, understand the possibility of adjusting the die-casting machine and process parameters, master the filling characteristics in different situations, and consider the mold processing method, drilling and Fixed form, so as to design a practical mold that meets production requirements.
