[0002] Stamping is a pressure processing method that uses a mold installed on a stamping machine to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts. However, after stamping, metal particles or impurities often remain on the inner cavity surface of the lower mold. When the mold is used again, it will affect the surface finish of the produced parts. Therefore, after the mold is stamped, the inner cavity surface of the mold needs to be cleaned, resulting in low processing efficiency. Utility Model Content

[0025] The lower end surface of the upper mold 102 is fixedly connected to two left-right symmetrical connecting sleeves 104 .

[0026] The connecting sleeve 104 can be threadedly connected to a connecting rod 103 . The lower end of the connecting rod 103 passes through the lower mold 101 and is detachably fixedly connected to a connecting block 105 . The connecting rod 103 is slidably connected to the lower mold 101 .

[0027] The connecting block 105 is slidably connected to the second sliding rod 106 , and the second sliding rod 106 is fixedly connected to a limiting plate 107 at one end surface away from each other.

[0028] The front and rear end surfaces of the first sliding rod 114 are respectively fixedly connected with a sliding plate 115 .

[0031] Working principle:

[0032] When in use, the lower die 101 and the upper die 102 are fixedly mounted on the upper and lower seats of the punching machine through the mounting holes 116, and then the metal material to be punched is placed between the lower die 101 and the upper die 102, so that the metal material covers the groove of the lower die 101, and the connecting rod 103 of appropriate length is selected according to the distance between the lower die 101 and the upper die 102, so that when the upper die 102 is not punched, the upper end of the cleaning arc plate 108 is flush with the upper end surface of the lower die 101;

[0033] When stamping, the punching machine drives the upper die 102 to move downward, and then the metal material is stamped through the cooperation of the convex block of the upper die 102 and the groove of the lower die 101, and the parts produced by stamping fall. When the upper die 102 moves downward, the upper die 102 drives the connecting rod 103 to move downward, and then drives the connecting block 105, the second sliding rod 106 and the limiting plate 107 to move downward, and then drives the first sliding rod 114 to move downward. Under the restriction of the inclined groove 113, when the metal material is about to be contacted for stamping, the two cleaning arc plates 108 are away from each other and located at the lower side of the lower die 101, which does not affect the stamping work and the falling of parts.

[0034] Then the upper mold 102 is driven to reset. During the resetting process of the upper mold 102, the two cleaning arc plates 108 are driven to move upward, and under the restriction of the inclined groove 113, the two cleaning arc plates 108 are driven to move closer to each other while moving upward, so that the outer side walls of the two cleaning arc plates 108 are slidingly connected to the groove of the lower mold 101. The two cleaning arc plates 108 continue to move upward, and the residual metal in the groove of the lower mold 101 can be removed by the cleaning arc plates 108 to complete self-cleaning.
