The die of Lead Die Casting is an important part of fixed die and moving die. The fixed die is fixed on the fixed die mounting plate of the die casting machine and connected with the pressure chamber of the die casting machine. The movable die is installed on the movable die mounting plate of the die casting machine, and is closed or separated from the fixed die along with the movement of the movable plate of the movable die.

In the process of die casting of lead die casting, it is mainly divided into molding part, die frame part, gate system, overflow system, ejection mechanism, guide parts and so on.

The forming part is the main component that determines the shape and size accuracy of lead die casting. Forming the outer surface of the casting is called cavity, and forming the inner surface of the casting is called core. The die frame part is the frame that combines and fixes the die-casting dies according to the rules and positions so that the die-casting dies can be installed in the die-casting machine; The gate system refers to the part that communicates the die-casting mold cavity and the die-casting machine room, that is, the channel through which the metal liquid enters the mold cavity; The overflow system is to exhaust the gas in the runner and cavity of the pressure chamber, which generally includes the exhaust passage and overflow trough; Ejection mechanism is a mechanism that fixes the casting to make the forming parts of die casting die come out; Guide parts are parts that guide each sliding part in the mold.

When designing lead die casting, we should be familiar with the characteristics and technical specifications of die casting machines to meet the basic requirements of lead die casting, such as mechanical properties and surface quality. Lead die casting have good application effect, and adopt good die structure, which meets the technological requirements of die casting production. Appropriate die materials should be selected to match the appropriate manufacturing quality, so that the die casting die can be operated conveniently and reliably.
