After completion, the new movable bottom mold 111 is placed above the multiple placement grooves 110, and then the multiple support blocks 15 are clamped to the movable bottom mold 111 by rotating the adjusting screws 16, thereby completing the replacement of the movable bottom mold 111. Through the above structure, the mold can be adjusted more conveniently, so that the mold can punch workpieces with different processing requirements.

[0024] like Figures 1 to 5 As shown, a support plate 2 is fixedly connected to the middle of the mold base 1; a support rod 21 is fixedly connected to the top of the support plate 2; a plurality of support columns 22 are detachably installed on the top of the support rod 21; a third circular groove 23 is opened at the bottom of the support column 22; a magnet 24 is slidably connected to the middle of the third circular groove 23; the support rod 21 is made of magnetic metal; during operation, after the movable bottom mold 111 is placed on the plurality of placement grooves 110, the plurality of support columns 22 will support the bottom of the movable bottom mold 111, thereby reducing the deformation of the middle part of the movable bottom mold 111 during stamping, and improving the processing accuracy to a certain extent. At the same time, the positions of the plurality of support columns 22 can be conveniently adjusted according to the opening of the movable bottom mold 111, so that the plurality of support columns 22 avoid the holes at the bottom of the movable bottom mold 111, so that after a part of the processing material is stamped and cut off, the cut material can fall directly without being blocked by the support columns 22, thereby improving the convenience of using the mold.

[0025] like Figures 1 to 4As shown, a pair of slide rails 3 are fixedly connected to the bottom of the mold base 1; a collection box 31 is slidably connected to the top of the slide rails 3; after part of the material is cut off by punching and cutting, the cut waste will fall into the inside of the collection box 31, thereby facilitating the collection of the waste and subsequent reprocessing of the waste.

[0026] like Figures 1 to 4 As shown, a partition fence 4 is fixedly connected to the middle of the collecting box 31; the partition fence 4 is arranged at a distance above the bottom of the collecting box 31; when the workpiece is stamped, a lubricant is applied to the surface of the workpiece to reduce the wear between the workpiece and the mold, and when the waste falls, the waste will fall on the top of the partition fence 4, and the remaining part of the lubricant on the surface of the waste will drip to the bottom of the partition fence 4, so that this part of the lubricant can be recycled and reused to reduce the waste of resources.

After completion, the new movable bottom mold 111 is placed above the plurality of mounting grooves 110, and then the plurality of supporting blocks 15 are rotated to clamp the movable bottom mold 111, thereby completing the replacement of the movable bottom mold 111, so that workpieces with different requirements can be punched. After the movable bottom mold 111 is placed on the plurality of mounting grooves 110, the plurality of supporting columns 22 will support the bottom of the movable bottom mold 111, thereby reducing the movable bottom mold 111 during punching. The deformation of the middle part of the mold 111 improves the processing accuracy to a certain extent. At the same time, the positions of the multiple support columns 22 can be conveniently adjusted according to the opening of the movable bottom mold 111, so that the multiple support columns 22 avoid the holes at the bottom of the movable bottom mold 111, so that after a part of the processing material is punched out, the cut material can fall directly without being blocked by the support columns 22. After part of the material is cut out by punching and cutting, the cut waste will fall into the inside of the collection box 31. When the waste falls, the waste will fall above the dividing column 4, and the remaining part of the lubricating liquid on the surface of the waste will drip to the bottom of the dividing column 4. The filter plate 5 can filter some impurities in the lubricating liquid to make a cleaner lubricating liquid fall.
