This invention discloses a magnesium alloy vehicle frame die-casting molding apparatus, belonging to the technical field of die-casting equipment. It includes a machine base, on which a base platform and a fixed mold are fixedly mounted. An injection chamber is fixedly mounted on the base platform, and a cavity is formed on the fixed mold.

Mechanical transmission allows the venting position and diameter to adapt to changes in cavity pressure and gas volume in real time, matching the filling rhythm and significantly improving die-casting quality and production stability.
