Trimming die

The utility model discloses a trimming die, and relates to the technical field of sheet metal part machining. The device comprises a workbench, the outer side of a rotating column is fixedly sleeved with driven teeth, the top of the rotating column is provided with a vibration block, the output end of a first motor is connected with a rotating shaft, and the outer side of the rotating shaft is fixedly sleeved with driving teeth; the folding rod is driven by the second motor to rotate, so that the striking head can transversely move back and forth to impact the vibration block in a reciprocating manner, the lower die is vibrated, the upper die is driven to move back and forth, the punching head is driven to move back and forth, the punching head is driven to move back and forth, and the punching head is driven to move back and forth. Therefore, the separation efficiency between the sheet metal stamping part and the lower mold is improved, and the effect of rapid demolding is achieved. And the lower mold is rot
