Die-casting molds with correct and reasonable structure are a prerequisite for the smooth production of die-casting parts, and they play an important role in ensuring the quality of castings (pass rate). The service life of a die-casting mold usually refers to the number of die-casting modules (including die-casting production) that occur through careful design and manufacturing, under normal conditions of use, and natural damage that occurs under good maintenance. Therefore, when designing the mold, it is necessary to comprehensively 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, grasp the filling characteristics under different conditions, and consider the method of die-casting mold processing, Only after drilling and fixing the form can we design a China blowing mould mold that is practical and meets the production requirements. The die-casting parts have been stuck to the fixed mold.　　

If the mold design is reasonable, there will be fewer problems encountered in actual production, and the casting pass rate will be high. Although the finish of the fixed mold cavity is very polished, the phenomenon of sticking to the fixed mold still occurs due to the deep cavity. Number of scraps in). As mentioned at the beginning, the filling time of the molten metal is extremely short, and the specific pressure and flow rate of the molten metal are very high, which is extremely harsh for the die-casting mold, coupled with the impact of the alternating stress of chilling and heating.. On the contrary, the die-casting mold design is unreasonable, such as: when the die-casting parts are designed, the wrapping force of the moving and fixed molds is basically the same, and the gating system is mostly in the fixed mold, and it is produced on a die-casting machine where the punch can not feed after the injection, so normal production cannot be performed.

The mold design is essentially to predict the various factors that may occur in the die-casting production The comprehensive reflection.Die-casting molds are one of the three major elements of die-casting production. All have a great impact on the service life of die-casting molds. 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 prerequisite for the correct selection and adjustment of various process parameters
