Position displacement is prone to occur when the mold is closed, resulting in unqualified molds. It also has the disadvantages of complex structure, high manufacturing cost, long manufacturing cycle, and inability to automatically control temperature. Therefore, a large torque motor rotor punching mold is needed to improve the above problems. Utility Model Content
