[0002] The double extrusion pin mechanism in alloy die casting molds is a key component used in the die casting process to extrude and fill materials such as aluminum alloys. This mechanism typically consists of two extrusion pins that apply pressure when the mold closes, forcing the molten alloy material into the mold cavity to ensure uniform filling and achieve the desired shape and size.

[0003] The existing double extrusion pin mechanism of an alloy die casting mold has the following disadvantages: Currently, the process of changing ejector pins or pin sleeves in most double extrusion pin mechanisms is cumbersome for parts processing personnel, which makes it inconvenient for them to change ejector pins and reduces their work efficiency.
