3. Basic principles of die-casting molds

Understanding the fundamentals of die casting molds is critical to efficient production.

A brief description of the die casting process

Die casting is a process in which molten metal is injected into a mold to create parts. The process includes the following key steps:

  1. Mold closure: The two halves of the mold, the female and male molds, are closed to form the mold cavity.

  2. Metal injection: Molten metal material is injected into the mold cavity through the injection system.

  3. Cooling: The metal cools and solidifies in the mold, taking the desired shape.

  4. Demolding: The finished part is released from the mold.

The design of the mold directly affects the efficiency of the process and the quality of the parts. Optimized mold design can ensure that metal fully fills the mold cavity, avoids defects, and increases production speed.

Selection of mold materials and their importance

Selecting the appropriate mold material is critical to mold performance and longevity. The following are some commonly used mold materials:

  • Steel: Steel molds have excellent wear resistance and durability and are suitable for high-volume production.

  • Copper Alloy: Copper alloy molds have excellent resistance to high temperature environments and are suitable for applications with special requirements.

  • Special alloy: Special alloy molds can meet special material and process requirements and are widely used in aerospace and other fields.

Mold material selection needs to consider operating conditions, metal type and mold life to ensure optimal performance.

Good mold design is the key to a successful die casting process. Here are someMold design points:

  • Main components of the mold: A typical die-casting mold consists of two parts, the female mold and the male mold. Their design should take into account the geometry and dimensions of the finished product. The gap between the female and male molds must be small enough to ensure that the metal can fully fill the mold cavity.

  • Design of injection system: The injection system is responsible for injecting molten metal into the mold cavity. Its design needs to ensure that the metal is evenly distributed and avoids gas pores and other defects.

  • Design of cooling and heating systems: Cooling and heating systems are critical to controlling mold temperature. Proper temperature control can impact part quality and production efficiency.
