Multiple stamping parts 423 are fixedly connected to the top and bottom of the support frame 420 by bolts. An upper die seat 300 is welded to the output end of the stamping part 423.

[0036] It is worth noting that, in order for the base 100 to position the lower mold base 200, specifically, the base 100 is hollow, and multiple guide rods 120 are inserted inside the hollow structure of the base 100. These guide rods, together with the lead screw 110, improve the stability of the lower mold base 200 when it moves. The base 100 has multiple fixing grooves integrally formed inside, and springs 101 are welded inside the fixing grooves. A limit ball 102 is welded to the output end of the springs 101, and a handle is sleeved on the output end of the lead screw 110 through the base 100.

[0037] Next, to facilitate the fixing of the lower mold plate 210 by the lower mold base 200, specifically, two circular grooves 201 are opened on the side wall of the lower mold base 200 to facilitate the sliding of the limit ball 102. Three limit grooves 202 are opened inside the circular grooves 201 to cooperate with the limit ball 102 for positioning. A threaded hole is opened at the bottom of the side wall of the lower mold base 200, and the internal thread of the threaded hole matches the external thread of the lead screw 110. Multiple guide holes are opened on both sides of the bottom of the side of the mold base. A dovetail groove is opened at the top of the lower mold base 200, and the lower mold plate 210 is inserted into the dovetail groove. A second spring 230 is welded inside the lower mold base 200. A limit block 220 is welded to the top of the second spring 230. The top of the limit block 220 passes through the dovetail groove and is integrally connected to the limit strip.

[0038] Meanwhile, to facilitate the fixing of the upper mold plate 310 by the upper mold base 300, specifically, a spring 301 is welded inside the upper mold base 300, a slider 302 is welded to the side wall of the spring 301, the top of the slider 302 passes through the upper mold base 300 and is integrally connected to a slide bar, a square groove is opened at the bottom of the upper mold base 300, a magnetic plate 303 is fixedly connected inside the square groove by screws, the upper mold plate 310 is inserted inside the square groove, a metal plate 311 is fixedly connected to the top of the upper mold plate 310 by screws, and a square insertion hole is opened at the contact position between the side wall of the upper mold plate 310 and the slider 302 to facilitate the sliding insertion of the slider 302 and fix the upper mold plate 310.

[0039] Furthermore, for the rotational positioning of the support frame 420, specifically, the side wall of the support frame 420 is integrally formed and connected to two connecting discs 422.

[0043] Combination Figures 1-5 The specific usage process of a stamping die according to this embodiment is as follows:

[0044] 1. When switching the lower mold base 200, the screw 110 is rotated by the handle, which cooperates with the threaded hole on the side wall of the lower mold base 200 to make the lower mold base 200 move horizontally. During the movement, the limit ball 102 first contacts the circular groove 201. At this time, the limit ball 102 slides and compresses the spring 101. Then, when the limit ball 102 moves to the opening of the limit groove 202, it receives the thrust from the spring 101, which makes the limit ball 102 insert into the limit groove 202. When all three limit balls 102 are inserted into the three limit grooves 202, the positioning of the lower mold base 200 is completed.

[0045] 2: When replacing the mold plate, press down the limiting block 220 on the side wall of the mold base 200. Then the limiting block 220 moves and compresses the second spring 230. Then slide the lower mold plate 210 out of the dovetail groove. Then slide the new lower mold plate 210 into the dovetail groove. Then stop pressing down the limiting block 220. The limiting block 220 moves upward with the push of the second spring 230, limiting and fixing the lower mold plate 210. When replacing the upper mold plate 310, slide the sliding strip integrally formed on the top of the slider 302 to move the slider 302 out of the square insertion hole opened on the side wall of the upper mold plate 310. Then insert the new upper mold plate 310. The upper mold plate 310 is magnetically fixed to the upper mold base 300 through the magnetic suction plate 303. Then release the slider 302. The slider 302 receives the push of the third spring 301 and slides into the square insertion hole to limit and fix the upper mold plate 310.

[0046] 3: When rotating and adjusting the upper mold base 300, hold the square handle on the side wall of the plug 402 and pull it outward to move the plug 402 out of the circular insertion hole on the side wall of the connecting plate 422. Then, control the servo motor 411 to run through the control panel 405. The servo motor 411 controls the support frame 420 to rotate. After the rotation is completed, release the plug 402. The plug 402 receives the pushing force of the spring 404 and inserts into the circular insertion hole to limit and fix the support frame 420.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
