Description

Technical Field

[0001] The utility model relates to the field of stamping dies, in particular to a stamping die capable of automatically cleaning waste materials. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging.

[0003] During the stamping process of the circuit board, the waste material corresponding to the opening will be discharged from the blanking hole of the lower template and the discharge port of the lower die base in sequence. However, the existing stamping die can easily cause waste material blockage, resulting in unsatisfactory stamping quality and even damage to the stamping die itself. Utility Model Content

[0028] The upper clamping plate 1 drives the first rack 10 to move in the vertical direction, thereby causing the first gear 12 and the second gear 13 to rotate. The rotation of the second gear 13 drives the second rack 11 to move in the horizontal direction. The horizontal movement of the second rack 11 drives the push plate 14 to move in the stacking space 7. During the rising process of the upper clamping plate 1, the second rack 11 drives the push plate 14 to take the waste away from the stacking space 7.

[0029] It should be noted that the utility model can convert the vertical movement into the horizontal movement through the waste cleaning mechanism, so that the upper mold moves in the vertical direction and drives the push plate 14 to move in the horizontal direction through the transmission, so that the push plate 14 takes the waste away from the stacking space 7.
