Secondary surface finishing die device

The utility model relates to the field of surface finishing, in particular to a secondary surface finishing mold device. The secondary surface finishing mold device comprises a workbench; the clamping mechanisms are arranged above and below the working table; the fixing mechanism is arranged in the workbench; wherein the number of the clamping mechanisms is two, the two clamping mechanisms are correspondingly arranged on the upper portion and the lower portion of the workbench, and grinding pieces are arranged in the two clamping mechanisms and used for grinding workpieces; and rotating mechanisms used for driving the clamping mechanisms to rotate are arranged on the sides, away from each other, of the two clamping mechanisms correspondingly. According to the secondary surface finishing die device, the two clamping mechanisms are arranged and located above and below the workbench respectively, the surfaces of the workpieces can be ground at the same time through the grinding pieces in the clamping mechanisms,
