[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model embodiment provides a special mold for metal bending machines with quick mold change capability, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a bending machine 1, an upper fixed seat 2 fixedly connected inside the bending machine 1, a quick-release assembly 3 at the bottom of the upper fixed seat 2, a lower dovetail groove 4 fixedly connected inside the bending machine 1, an adjusting assembly 5 inside the lower dovetail groove 4, the quick-release assembly 3 including an upper bolt 301, the upper bolt 301 being located on one side of the upper fixed seat 2, an upper dovetail groove 302 inside the upper fixed seat 2, an upper die 303 engaging inside the upper dovetail groove 302, a fixing bracket 304 fixedly connected to one side of the upper die 303, and the bottom of the fixing bracket 304... A first rotating handle 305 is rotatably connected, and a first screw 306 is fixedly connected to the top of the first rotating handle 305. A limit block 307 is threadedly connected to the outer wall of the first screw 306. A limit rod 308 is fixedly connected to the top of the fixing frame 304. A second screw 309 is threadedly connected to the inside of the limit block 307. A handle 310 is fixedly connected to one end of the second screw 309, and a clamping plate 311 is fixedly connected to the other end of the second screw 309. A lower bolt 312 is provided on one side of the lower dovetail groove 4, and a lower mold 313 is provided inside the lower dovetail groove 4. First, the upper dovetail... The dovetail groove 302 is placed inside the upper fixed seat 2, and then the bolt 301 is tightened to fix the upper dovetail groove 302 inside the upper fixed seat 2. At this time, the upper mold 303 can be engaged inside the upper dovetail groove 302. Then, the first rotating handle 305 is turned to drive the first screw 306 to rotate inside the limiting block 307, so that the limiting block 307 can move along the outer wall of the limiting rod 308 to prevent the upper mold 303 from disengaging from the upper dovetail groove 302. Then, the handle 310 is turned to drive the second screw 309 to rotate, so that the second screw 309 drives the clamping plate 311 to move. Clamp the upper dovetail groove 302 to complete the installation of the upper mold 303. Then, snap the lower mold 313 into the lower dovetail groove 4 and tighten the bolt 312 to complete the installation and fixation. When it is necessary to change the mold for producing different products, you can directly turn the handle 310 to disengage the clamping plate 311 from the fixation of the upper dovetail groove 302, and then turn the first rotating handle 305 to disengage the limiting block 307 from the limit of the upper mold 303. The upper mold 303 can then be removed for replacement. Remove the bolt 312 to disengage it from the fixation of the lower mold 313, and the lower mold 313 can then be replaced.

[0018] Furthermore, such as Figure 3 As shown, the first rotating handle 305 forms a movable structure with the first screw 306 and the limiting block 307. The bottom of the first screw 306 is fixedly connected to the top of the first rotating handle 305, and the outer wall of the first screw 306 is threadedly connected to the inside of the limiting block 307. This allows the first rotating handle 305 to drive the first screw 306 to rotate, which in turn causes the first screw 306 to drive the limiting block 307 to move.

[0019] Furthermore, such as Figure 3 As shown, the handle 310 forms a movable structure with the clamping plate 311 via the second screw 309, and one end of the second screw 309 is fixedly connected to one side of the handle 310, and the other end of the second screw 309 is fixedly connected to one side of the clamping plate 311, so that when the handle 310 drives the second screw 309 to rotate, the second screw 309 drives the clamping plate 311 to move.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the adjusting assembly 5 includes a protective shell 501, which is fixedly connected to one side of the lower mold 313. A second rotating handle 502 is rotatably connected to the outer wall of the protective shell 501. A drive wheel 503 is fixedly connected to one side of the second rotating handle 502. A transmission belt 504 is sleeved on the outer wall of the drive wheel 503, and a driven wheel 505 is sleeved on the inner wall of the transmission belt 504. A guide rod 506 is fixedly connected inside the lower mold 313. A left groove 507 and a right groove 508 are slidably connected to the outer wall of the guide rod 506. A first double-ended screw 509 is fixedly connected to one side of the drive wheel 503, and a second double-ended screw 509 is fixedly connected to one side of the driven wheel 505. The double-ended screw 510 can rotate the second handle 502 to drive the drive wheel 503 to rotate, which in turn drives the transmission belt 504 to rotate, which in turn drives the driven wheel 505 to rotate. This causes the drive wheel 503 to rotate inside the left groove 507 and the right groove 508 of the first double-ended screw 509. At the same time, the driven wheel 505 drives the second double-ended screw 510 to rotate inside the left groove 507 and the right groove 508. This causes the left groove 507 and the right groove 508 to move relative to each other along the outer wall of the guide rod 506, thereby adjusting the distance between the left groove 507 and the right groove 508. This allows for the adaptation to products of different thicknesses, reduces the number of mold changes, and improves production efficiency.

[0021] Furthermore, such as Figure 4 As shown, the drive wheel 503 forms a rotating structure with the driven wheel 505 through the transmission belt 504, and the transmission belt 504 is simultaneously sleeved on the outer wall of the drive wheel 503 and the driven wheel 505, so that when the drive wheel 503 drives the transmission belt 504 to rotate, the transmission belt 504 drives the driven wheel 505 to rotate.

[0022] Furthermore, such as Figure 4 As shown, the second rotating handle 502 forms a rotating structure with the first double-ended screw 509 through the drive wheel 503, and one side of the drive wheel 503 is fixedly connected to one side of the second rotating handle 502, and the other side of the drive wheel 503 is fixedly connected to one end of the first double-ended screw 509, so that when the second rotating handle 502 drives the drive wheel 503 to rotate, the drive wheel 503 drives the first double-ended screw 509 to rotate.

[0023] Furthermore, such as Figure 4 As shown, the drive wheel 503 forms a movable structure with the left groove 507 via the first double-ended screw 509, and one end of the first double-ended screw 509 is fixedly connected to one side of the drive wheel 503, and the outer wall of the first double-ended screw 509 is threadedly connected to the inner wall of the left groove 507, so that when the drive wheel 503 drives the first double-ended screw 509 to rotate inside the left groove 507, the left groove 507 moves along the outer wall of the guide rod 506.

[0024] Working principle: First, place the upper dovetail groove 302 in the upper fixed seat 2, then tighten the upper bolt 301 to fix the upper dovetail groove 302 in the upper fixed seat 2. At this time, the upper mold 303 can be engaged inside the upper dovetail groove 302. Then, tighten the first rotating handle 305 to drive the first screw 306 to rotate inside the limiting block 307, so that the limiting block 307 can move along the outer wall of the limiting rod 308, preventing the upper mold 303 from disengaging from the upper dovetail groove 302. Then, tighten the handle 310 to drive the second screw 309 to rotate, so that the second screw 309 drives the clamping plate 311 to move and clamp the upper dovetail groove 302, completing the installation of the upper mold 303. Engage the lower mold 313 in the lower dovetail groove 4, and then tighten the lower bolt 312 to complete the installation and fixation. When changing molds for different products, the handle 310 can be tightened directly to disengage the clamping plate 311 from the upper dovetail groove 302. Then, rotate the first rotating handle 305 to disengage the limiting block 307 from the upper mold 303, allowing the upper mold 303 to be removed for replacement. Remove the bolt 312 to disengage it from the lower mold 313, allowing the lower mold 313 to be replaced. Rotate the second rotating handle 502 to drive the drive wheel 503 to rotate, which in turn drives the transmission belt 504 to rotate, which in turn drives the driven wheel 505 to rotate. This causes the drive wheel 503 to rotate inside the left groove 507 and right groove 508 of the first double-ended screw 509. At the same time, the driven wheel 505 drives the second double-ended screw 510 to rotate inside the left groove 507 and right groove 508, causing the left groove 507 and right groove 508 to move relative to each other along the outer wall of the guide rod 506. This allows for adjustment of the distance between the left groove 507 and right groove 508, accommodating products of different thicknesses, reducing mold changes, and improving production efficiency.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
