The design of die-casting molds is a key link in the entire manufacturing process, which directly affects the quality and production efficiency of the product. The design needs to be carefully planned according to the specific shape, size and performance requirements of the die-casting. The rationality of the mold structure is the primary consideration in the design, which is not only related to the processing convenience and assembly efficiency of the mold, but also plays an important role in the smooth progress of the subsequent production process. Especially in the design of the pouring system and the exhaust system, it is necessary to ensure that the metal liquid can fill the mold smoothly and the gas can be effectively discharged to avoid the occurrence of casting defects.

In the design of the mold cavity, the changes in wall thickness and ribs should be kept uniform and gradual to reduce stress concentration and improve the durability of the mold. The use of a larger inner fillet radius can effectively reduce the occurrence of metal erosion and thermal fatigue near the gate. In addition, the layout of the cooling water channel must also be carefully designed to ensure the uniform distribution of the surface temperature of the mold cavity, so as to achieve the best die-casting effect and improve the molding quality of the product.

The choice of mold material has a direct impact on the service life of the mold and the quality of the die-casting. Usually, high-strength steel or other durable alloy materials are selected to meet the working requirements under high pressure and high temperature environments. In the process of material selection, multiple factors such as wear resistance, corrosion resistance, high temperature stability and mechanical processing performance need to be considered comprehensively. At the same time, it is necessary to make reasonable trade-offs based on the specific requirements and economic costs of die castings to ensure that the selected materials have good cost performance.

In the processing and manufacturing of die-casting molds, it is very important to strictly follow the design drawings for processing to ensure the dimensional accuracy and shape accuracy of the mold. During the machining process, special attention should be paid to controlling key parameters such as cutting speed, feed rate and back cutting amount to prevent excessive tool wear and workpiece hardening. For the die cutting of the mold, it is recommended to carry out the processing in a good annealing state and maintain appropriate hardness requirements to ensure the processing quality. In addition, the surface treatment process of the mold should not be ignored. For example, polishing, chrome plating and other treatments can significantly improve the surface quality and corrosion resistance of the mold and extend the service life of the mold.

The mold trial link is an important step in testing the quality of the mold and the accuracy of the die casting. During the mold trial process, the filling condition, dimensional accuracy and surface quality of the die casting should be carefully observed. According to the mold trial results, the mold needs to be adjusted and optimized as necessary to ensure that the final product meets the design requirements. At the same time, detailed records of various data during the mold trial process not only provide important reference basis for subsequent production, but also provide data support for continuous improvement.
