[0002] In the prior art, stamping a workpiece requires the use of stamping dies; with existing stamping dies, if the workpiece is to be stamped, a punch is required, and the punch can only play a stamping role. Punching, you need to replace a different punch
Moreover, for workpieces in the prior art, after punching the outer side, there are often burrs or protrusions protruding from the edge of the workpiece at the bottom of the punching hole, resulting in uneven punching bottom surface, and the entire workpiece does not come into contact with the punch after being pressed. part will be lifted

Abstract

The invention discloses a stamping mold. The stamping mold comprises a lower mold plate, wherein a stamping hole is formed in the middle of the lower mold plate; a workpiece is placed at the upper end of the stamping hole; a pressing plate is arranged on the upper end surface of the lower mold plate; a pressing plate groove is formed in the lower end of the pressing plate; a first sliding chute is formed in the lower end of the pressing plate groove; a first rack is arranged in the first sliding chute; the upper end of the first rack is fixedly connected to the lower end of the pressing plate; a second rack is arranged inside the lower mold plate parallel to the first sliding chute; the outer side end of the second rack is connected to a backing plate; opposite surfaces of the first rack and the second rack are provided with transmission tooth grooves; a transmission gear is arranged between the two racks; the two ends of the transmission gear are respectively meshed with the first rack and the second rack; and a plunger chip is arranged at the upper end of the workpiece. The stamping mold has the beneficial effects that the stamping mold is simple in structure; when being used for stamping the workpiece, the stamping mold can effectively prevent burrs and turnup from appearing on the lower end surface of the stamping hole, can also prevent the two ends of the workpiece from turning up and can realize notching and punching simultaneously without the need for replacement of the plunger chip.

Description

technical field [0001] The invention relates to a stamping die. Background technique [0002] In the prior art, stamping a workpiece requires the use of stamping dies; with existing stamping dies, if the workpiece is to be stamped, a punch is required, and the punch can only play a stamping role. For punching, you need to replace different punches. Moreover, for workpieces in the prior art, after punching the outer side, there are often burrs or protrusions protruding from the edge of the workpiece at the bottom of the punching hole, resulting in uneven punching bottom surface, and the entire workpiece does not come into contact with the punch after being pressed. part will be lifted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method that can effectively prevent the burrs from lifting up on the lower end surface of the punching hole when stamping the workpiece, and can also prevent the two ends of the wo...
