Detailed ways

Referring to Figures 1 to 5, a rotary cutting device includes an upper template 1 and a lower template 2, and the lower template 2 is provided with a movable mold 3 and four positioning columns 4 respectively located at the front, rear, left, and right of the movable mold 3, The inner side of the positioning column 4 is provided with a guide contact 5, and the side end surface of the movable mold 3 is provided with a guide structure adapted to the guide contact 5; 6 and the limit post 8 positioned at the outer side of the trimming fixed male 6, the lower end edge of the trimming fixed male 6 is a sharp blade, and the upper end of the trimmed fixed male 6 is connected with a positioning block 7 through an interlocking structure. Further, the interlocking structure includes an interlocking block arranged on the upper end of the trimming fixing male 6 and an interlocking hole arranged on the positioning block 7 to match the interlocking block. When assembling, the positioning The block 7 is placed on the upper end of the trimming fixing male 6, so that the linkage block is inserted into the linkage hole, the size of the linkage hole is larger than the linkage block, and the moving mold 3 is connected to the linkage block through the reset assembly 18. The lower formwork 2 is connected; the lower end of the upper formwork 1 is provided with a pressure film 10, and the lower end of the pressure film 10 is provided with a cavity 9 that can be covered on the positioning block 7, and the upper formwork 1 is connected with a drive Its die power assembly 11 that moves up and down. When cutting, the switch panel is set on the positioning block 7, and the pressing film is pressed against the limit column and drives the mobile mold to move downward. Restricted by the concave cavity 9, the remaining edges of the four sides of the switch panel are cut off by the edge trimmer, and there is no need to adjust the height of the cutter, which effectively improves the product qualification rate and reduces production costs.

Furthermore, the front side of the moving mold 3 is a first guide surface, the left side is a second guide surface, the rear side is a third guide surface, and the right side is a fourth guide surface; the first guide The first guide groove 12 is provided on the surface, and the first guide protrusion 13 corresponding to the first guide groove 12 is provided on the third guide surface; guide groove 14 and the third guide projection 15, the fourth guide surface is provided with a second guide projection 16 corresponding to the second guide groove 14, and a second guide projection 16 corresponding to the third guide projection 15 The third guide groove 17.
