The invention relates to a punching mold for a permanent magnet motor rotor. The punching mold for the permanent magnet motor rotor comprises a mold rack, an upper mold pad plate, a punch fixing plate, a magnetic leakage hole punch, a small magnetic steel groove punch, a lower mold body, a lower mold base, a lower mold pad plate, a large magnetic steel groove punch, a weight decrease hole punch, asmall magnetic leakage hole punch, a large magnetic leakage hole punch and center positioning shafts; the mold rack is formed by connecting two non-gap rolling guide columns, the upper mold pad plateis arranged in the center of the lower end face of the mold rack, the punch fixing plate is arranged at the lower end of the upper mold pad plate, and the upper mold pad plate and the punch fixing plate are fixed to the mold rack through bolts; multiple punches are fixed to the punch fixing plate; stripping plates are arranged at the lower ends of the punches, the lower mold pad plate is arrangedbelow the lower mold body, and the center positioning shafts are arranged on the side faces of the centers of the lower mold body, the lower mold pad plate and the lower mold base. The processed rotor punching product is high in positioning precision and cooperates with the center positioning shafts, the center positioning shafts can achieve accurate positioning, the quality of punching productsis guaranteed, and the processing efficiency of products is improved.
