Vertical movable plates one and two are slidably mounted on the bottom sides of the top plate, respectively. A pair of hydraulic cylinders for driving the movable plates one and two are horizontally fixed on the inner sides of the two side plates. A punch is detachably mounted on the side of the movable plate one near the movable plate two, and a die is detachably mounted on the side of the movable plate two near the movable plate one. When the punch and die are closed, they form a mold cavity. A liquid injection port communicating with the mold cavity is provided at the top of the die, making mold replacement and fixing convenient, die-casting of parts convenient, and parts easy to detach. After detachment, parts are easily guided to a conveying device, avoiding direct drop and damage.

[0003] However, the aforementioned molds, including some existing molds, generally rely on bolt-fastened assembly. When changing styles, it is necessary to repeatedly disassemble the connecting parts, which not only has a long operation cycle and high labor intensity, but also easily leads to the risk of thread stripping and the reduction of positioning accuracy, resulting in an abnormal increase in production line downtime. To address this, we propose a die-casting mold for automotive parts. Utility Model Content
