A precision casting method that fills molten alloy under high pressure and high speed conditions, and then cools and solidifies under high pressure. Die-casting mold (die-casting die) is a metal mold used to form castings in the die-casting forming process.

The die-casting mold structure consists of:

The fixed mold: fixed on the fixed mold mounting plate of the die-casting machine, with a sprue connected to the nozzle or pressure chamber. The movable mold: fixed on the die-casting motorized mold. When the mold is closed, the mold cavity and casting system are formed, and the liquid metal fills the mold cavity under high pressure; when the mold is opened, the movable mold and the fixed mold are separated, and with the help of the device The ejection mechanism on the movable mold pushes the casting out.

II). The die-casting mold structure is classified according to its function

Cavity: outer surface sprue (sprue sleeve) Molded parts 2 )Gating system mold runner (insert) core: inner surface gate remaining material (3) guide parts: guide pillar; guide sleeve (4) push-out mechanism: push rod (ejector pin), reset rod, push rod fixation Plate, push plate, push plate guide post, push plate guide sleeve. (5) Lateral core pulling mechanism: boss; hole (side), wedge block, limit spring, screw. (6) Overflow system: overflow Sprue, exhaust tank. (7) Cooling system (8) Support parts: fixed mold; movable mold base plate, cushion block (assembly, positioning, installation function)
