The utility model discloses a thin-wall aluminum alloy precision extrusion forming die which comprises a supporting mechanism, a limiting mechanism, a male die and a female die, the two ends of aluminum alloy are correspondingly located on first rotating rollers on the two sides of the female die respectively, and the two ends of the aluminum alloy are supported through the supporting mechanism; the telescopic end of a first electric cylinder extends downwards to drive a first transverse plate to move downwards, the first transverse plate drives a second U-shaped plate to enable a second rotating roller to move downwards till the second rotating roller makes contact with the top face of the aluminum alloy, and therefore through cooperative arrangement of two limiting mechanisms, the two ends of the aluminum alloy are lowered and not prone to upwarp when the aluminum alloy is extruded; the rotating end of a motor rotates to drive a first bevel gear to rotate, the first bevel gear drives a second bevel gear to
