The utility model provides a stamping die for achieving material stamping based on two-stage positioning. The stamping die comprises a fixed die and a movable die matched with the fixed die. The fixed mold comprises a fixed base, a fixed mold core, a blank holder, an initial positioning piece and a secondary positioning piece; the fixed mold core is fixed on the fixed base, the blank holder is slidably arranged on the fixed base and sleeves the periphery of the fixed mold core, the initial positioning piece is arranged on the blank holder, and the secondary positioning piece is telescopically arranged on the blank holder through the elastic piece. And the secondary positioning piece is closer to the fixed mold core than the initial positioning piece. According to the stamping die for achieving material stamping based on two-stage positioning, materials can be positioned twice before stamping and in the die pressing process, so that deviation and dislocation of the materials are avoided, and the machining prec
