　　Design points of CNC die-casting molds

　　The design of CNC die-casting molds is a key link in ensuring product quality and production efficiency. Here are some key points for designing CNC die-casting molds:

　　1. Selection of mold materials: The choice of mold materials directly affects the service life of the mold and the quality of the parts. High strength and high wear resistant steel is usually selected to withstand high pressure and high temperature.

　　2. Mold structure design: Mold structure design needs to consider the geometric characteristics and processing requirements of the parts. A reasonable mold structure can improve processing efficiency, reduce processing time and costs.

　　3. Cooling system design: The control of mold temperature is crucial during the die-casting process. Reasonable cooling system design can improve the service life of molds and the quality of parts.

　　4. Exhaust system design: During the die-casting process, the gas inside the mold needs to be discharged in a timely manner, otherwise it will affect the quality of the parts. A well-designed exhaust system can improve die-casting efficiency and product quality.

　　5. Demoulding slope and draft angle: Appropriate demoulding slope and draft angle can ensure smooth demoulding of parts, reduce mold damage and part defects.

　　6. Pouring system design: The design of the pouring system directly affects the flow and filling effect of the molten metal. Reasonable design can reduce pouring time and improve the quality of parts.

　　7. Number and layout of mold cavities: The design of the number and layout of mold cavities needs to consider production efficiency and the balance of the mold. Reasonable layout can improve production efficiency and reduce stress concentration in molds.
