Detailed Description

The utility model is further described below with reference to the accompanying drawings:

as shown in fig. 1 to 4, a punching die with a waste material retaining structure comprises a mounting base plate 1 and a cutter assembly 2, wherein the cutter assembly 2 is fixed below the mounting base plate 1, the cutter assembly 2 comprises an inner contour cutter 21, a transverse cutter 22, a longitudinal cutter 23, a middle bevel cutter 24 and an outer bevel cutter 25, the upper ends of the transverse cutter 22 and the upper ends of the longitudinal cutters 23 are both fixed on the mounting base plate 1, the transverse cutter 22 is provided with two groups along the X axis direction, and is provided with a plurality of groups along the Y axis direction, the longitudinal cutter 23 is provided with three groups along the X axis direction, and is provided with a plurality of groups along the Y axis direction, two groups of adjacent longitudinal cutters 23 in the X axis direction and two groups of adjacent transverse cutters 22 in the Y axis direction enclose a rectangular punching cavity 26, the inner contour cutter 21 is fixed on the mounting base plate 1, the plurality of groups of inner contour cutters 21 are respectively corresponding in the plurality of groups of rectangular punching cavities 26, the middle bevel cutter 24 is fixed on the mounting base plate 1 and corresponds to the corner of the inner side of the rectangular cavity 26, the outer bevel cutter 25 is fixed on the mounting base plate 1 and corresponds to the corner of the outer side of the rectangular cavity 26, the outer corner of the rectangular cavity 23 is adjacent to the rectangular cavity 23, and the outer triangular column 23 is provided with a triangular column 27 corresponding to the inner side of the triangular column 23, and the triangular column 231 is provided with a protruding hole of the waste material 11.

The mounting base plate 1 is provided with a second scrap hole 12, and the second scrap hole 12 corresponds to the inner contour cutter 21.
