Die casting machine is a machine used for pressure casting. Including two kinds of hot press room and cold press room. Later, they are divided into two types: straight type and horizontal type. The die-casting machine hydraulically injects the molten metal into the mold under pressure to cool and form. After the mold is opened, a solid metal casting can be obtained, which is initially used for die-casting type.

With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, die-casting technology has achieved extremely rapid development.

The die-casting machine is mainly composed of mold clamping mechanism, injection mechanism, hydraulic system and electric control system. [3] In addition, the die-casting machine also has parts and bases, other devices, auxiliary devices and other parts.

Clamping mechanism

Drive the die-casting mold to close and open. When the mold is closed, it has enough ability to lock the mold tightly to ensure that the mold parting surface will not expand during the injection filling process. The force to lock the mold is called the clamping force (also known as the closing force), the unit is kilonewton (kN), which is the primary parameter that characterizes the size of the die-casting machine.

Injection mechanism

Push the molten metal in the pressure chamber at the specified speed, and have enough energy to flow it through the runner and inner gate in the mold, and then fill it into the mold cavity, and then maintain a certain pressure to transmit to the solidifying molten metal. Until the die casting is formed. After the injection action is completed, the injection punch returns to reset.

Hydraulic system

Provide enough power and energy for the operation of the die casting machine.

Electrical control system

Control the execution of each mechanism of the die-casting machine to run according to a predetermined program.
