The utility model discloses a pre-forging die for a working cylinder of an aluminum alloy hydraulic spring control mechanism, and relates to the pre-forging die for the working cylinder of the aluminum alloy hydraulic spring control mechanism. The problem that an existing working cylinder is unstable in clamping during pre-forging is solved. An aluminum alloy hydraulic spring control mechanism working cylinder pre-forging die is composed of an upper die body and a lower die body. Wherein the upper die and the lower die are arranged in an oppositely-combined mode, an upper die cavity and a lower die cavity are formed in the oppositely-combined faces of the upper die and the lower die respectively, a cavity is defined by the upper die cavity and the lower die cavity, and a plurality of connecting inserting holes and hoisting inserting pin holes are evenly formed in the two ends of the upper die and the two ends of the lower die in the axial direction of the cavity respectively. The pre-forging clamp is used for
