Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Referring to Figures 1-6 A punch press for keyboard, comprising upper mold 1, lower mold 2, the top of upper mold 1 is fixedly connected with connecting block 3, connecting block 3 is slidably connected with upper mounting table 4, lower mold 2 is slidably connected with lower mounting table 5, the two sides of lower mounting table 5 are provided with clamping structure 6 capable of clamping larger lower mold 2, and extrusion structure 7 capable of clamping smaller lower mold 2 is arranged on clamping structure 6.

[0023] It should be noted that upper mold 1 and lower mold 2 are prior art, and the specific model specification needs to be selected and determined according to the actual specification of the device. The specific selection calculation method adopts the prior art in the art, and therefore will not be described in detail.

[0024] Further, the two sides of connecting block 3 are provided with symmetrically distributed clamping grooves 8, and the bottom of upper mold 1 is provided with extrusion protrusion 9.

[0025] The shape and size of the outer wall of connecting block 3, clamping groove 8 and convex gap 10 are matched, so that upper mold 1 can be quickly connected with upper mounting table 4.

[0026] Further, the outer wall of upper mounting table 4 is provided with convex gap 10, the top of upper mounting table 4 is provided with uniformly distributed limiting holes 11, and limiting clamping jaw 12 capable of limiting the movement of upper mold 1 is arranged on limiting hole 11.

[0027] The limiting hole 11 is arranged in front of the connected connecting block 3, so that when the limiting clamping jaw 12 is inserted into the limiting hole 11, the connecting block 3 is just limited in the convex gap 10.

[0028] Further, the outer wall of the lower mold 2 is provided with symmetrically distributed sliding grooves 13, and the top end of the lower mounting table 5 is fixedly connected with symmetrically distributed L-shaped limiting strips 15.

[0029] The lower mold 2 is slidably connected with the L-shaped limiting strips 15 through the sliding grooves 13.

[0030] Further, the clamping structure 6 includes uniformly distributed sliding holes 16, sliding rods 17, springs 18, fixed blocks 19 and sliding openings 20. The sliding holes 16 are arranged on the outer wall of the lower mounting table 5, the sliding rods 17 are slidably connected with the sliding holes 16, one end of the spring 18 is fixedly connected with one end of the sliding rod 17 located in the sliding hole 16, the other end of the sliding rod 17 is fixedly connected with the fixed block 19, and the sliding opening 20 is arranged on the fixed block 19.

[0031] The other end of the spring 18 is fixedly connected with the inner wall of the sliding hole 16, so that the sliding rod 17 can be pulled and will not easily come off the sliding hole 16, and the sliding rod 17 can also be pulled to move inward.

[0032] Further, the extrusion structure 7 includes a locking plate 21, a moving block 22, a rotating rod 23 and a limiting rod 24. The locking plate 21 is slidably connected with the sliding opening 20, the rotating rod 23 is threadedly connected with the locking plate 21, the rotating rod 23 is rotationally connected with the moving block 22, the limiting rod 24 is slidably fixedly connected with the moving block 22, and the limiting rod 24 is slidably connected with the locking plate 21.

[0033] The extrusion structure 7 is manually rotated by rotating the rotating rod 23, and the rotating rod 23 drives the moving block 22 to move, so as to approach the outer wall of the lower mold 2.

[0034] The working principle is that the disassembly and replacement of the upper mold 1 can be achieved by aligning the connecting block 3 and the clamping groove 8 at the top end of the upper mold 1 with the convex notch 10 on the upper mounting table 4 and inserting them into the upper mounting table 4, inserting the limiting clamping jaw 12 into the limiting hole 11 when reaching the deepest position, and limiting the movement of the upper mold 1, so as to complete the disassembly and replacement of the upper mold 1.

[0035] The disassembly and replacement of the lower mold 2 is achieved by aligning the sliding grooves 13 on both sides of the lower mold 2 with the middle of the L-shaped limiting strips 15 and then inserting them into the L-shaped limiting strips 15. When a larger lower mold 2 is encountered, the fixed block 19 can be manually moved outward, the fixed block 19 drives the sliding rod 17 to move and stretch the spring 18, and after reaching the appropriate position, the fixed block 19 is loosened, and under the elastic action of the spring 18, the fixed block 19 returns to the original position to clamp the lower mold 2 in the middle. When a smaller lower mold 2 is encountered, the rotating rod 23 can be manually rotated, the rotating rod 23 drives the moving block 22 to move, and the moving block 22 approaches the outer wall of the lower mold 2 until the outer wall of the lower mold 2 is abutted, so as to complete the disassembly and replacement of the lower mold 2.

[0036] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
