Die-casting mold is one of the three major factors of die-casting production. The correct and reasonable mold is the prerequisite for the smooth progress of die-casting production, and plays an important role in ensuring the quality of castings. Die Casting Die casting is a method of casting liquid die forging. The die casting die forging process is a process performed on a dedicated die casting forging machine. The basic process is: the metal liquid is first filled into the cavity of the mold by low speed or high speed casting, and the mold has a movable cavity surface, which is pressed and forged with the cooling process of the molten metal, thereby eliminating the shrinkage of the blank. The loose defect also causes the internal structure of the blank to reach the forged broken grain. The overall mechanical properties of the blank are significantly improved.

Die-casting mold is one of the three major factors of die-casting production. The correct and reasonable mold is the prerequisite for the smooth progress of die-casting production, and plays an important role in ensuring the quality of castings. Due to the characteristics of the die-casting process, the correct selection of various process parameters is the decisive factor for obtaining high-quality castings, and the mold is the premise of being able to correctly select and adjust various process parameters. The mold design is essentially the prediction of various factors that may occur in the die-casting production. Comprehensive reflection. If the mold design is reasonable, there are fewer problems encountered in actual production, and the pass rate of the castings is high. On the contrary, the mold design is unreasonable. The casting force of the fixed mold is basically the same when the casting is designed. The casting system is mostly fixed in the mold, and it is produced on the Guannan die-casting machine where the punch cannot be fed after the shot, and it cannot be produced normally. The casting has been stuck to the fixed mold. Although the finish of the mold cavity is very light, the phenomenon of sticking to the fixed mold still occurs due to the deep cavity. Therefore, in the design of the mold, it is necessary to comprehensively analyze the structure of the casting, familiar with the operation process of the die-casting machine, to understand the possibility of adjustment of the die-casting machine and process parameters, to grasp the filling characteristics under different conditions, and to consider the method of drilling, drilling After the eye and the fixed form, it is possible to design a mold that is realistic and meets the production requirements. 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. This is extremely difficult for the die-casting mold, and the impact of the alternating stress of the chilling heat. The effect has a great influence on the service life of the mold. The service life of a mold usually refers to the number of molds that are die-cast (including die-casting production) through careful design and manufacture, under normal conditions of use, combined with natural damage caused by good maintenance, before being scrapped and scrapped. The number of scraps).
