It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5The present invention provides a multi-angle bending forming mold, comprising: a workbench 1 and two adjusting plates 408. A lower mold base 2 is installed on the upper surface of the workbench 1. Two side templates 3 are fixedly connected to the upper surface of the lower mold base 2. An adjusting device 4 is provided on the upper surface of the lower mold base 2.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 4The adjusting device 4 includes a bottom groove 417, which is formed on the upper surface of the lower mold base 2. Side mold plates 3 are fixedly connected to the inner wall of the bottom groove 417. A screw 401 is rotatably connected to the side of the two side mold plates 3 closest to each other. Both ends of the screw 401 have threads in opposite directions. A motor 414 is fixedly connected to the side of one side mold plate 3 furthest from the other. The output end of the motor 414 is fixedly connected to the screw 401. A support plate 409 is fixedly connected to the inner wall of the bottom groove 417. The screw 401 is rotatably connected to the support plate 409. Two adjusting blocks 402 are slidably connected to the inner wall of the bottom groove 417. Both adjusting blocks 402 are threadedly connected to the screw 401. Connecting rods are fixedly connected to both sides of each adjusting block 402. Button 403, with connecting plates 404 rotatably connected to the arc surfaces of both connecting buttons 403. Two triangular plates 410 are fixedly connected to the upper surface of the lower die base 2. Adjusting rods 411 are fixedly connected to the sides of the two triangular plates 410 that are close to each other. The adjusting rods 411 are located directly above the support plate 409. Two circular ring rods 412 are fixedly connected to the sides of the two adjusting plates 408 that are close to each other. The circular ring rods 412 are rotatably connected to the adjusting rods 411. A mounting block 405 is fixedly connected to the side of the adjusting plate 408 near the bottom groove 417. Circular buttons 407 are fixedly connected to both sides of the mounting block 405. The circular buttons 407 are rotatably connected to the connecting plate 404. An arc groove 406 is opened on the side of the mounting block 405 away from the adjusting plate 408. This achieves the effect of bending the workpiece at multiple angles without changing the lower die base 2 when bending operations are required, thereby improving work efficiency and the applicability of the die. Several rubber strips 418 are fixedly connected to the side of the adjusting plate 408 away from the bottom groove 417, and the rubber strips 418 are evenly distributed on the surface of the adjusting plate 408. This increases the friction between the adjusting plate 408 and the workpiece when it is placed on the two adjusting plates 408, preventing the workpiece from sliding on the adjusting plate 408. A fixing ring 413 is fixedly connected to the side of one of the side templates 3 near the motor 414, and a protective cover 415 is slidably connected to the inner wall of the fixing ring 413. This protects the motor 414 when it is working, and the fixing ring 413 provides limiting support for the protective cover 415. Several heat dissipation holes 416 are evenly distributed on the arc surface of the protective cover 415. When the motor 414 is protected by the protective cover 415, the heat generated by the motor 414 during operation can be dissipated through several heat dissipation holes 416, thereby preventing the motor 414 from being damaged due to excessive heat.

[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 5The upper surface of the workbench 1 is provided with several limiting devices 5, each of which includes a concave plate 501. A rectangular groove 502 is provided on one side of the concave plate 501. A rotating rod 503 is rotatably connected to the inner wall of the rectangular groove 502. Rod heads 509 are fixedly connected to both ends of the rotating rod 503. A limiting block 504 is fixedly connected to the arc surface of the rotating rod 503. The limiting block 504 is "L" shaped. The short arm end of the limiting block 504 is inclined. A limiting groove 505 is provided on the lower surface of the short arm end of the limiting block 504. The limiting groove 505 is semi-circular. The long arm end of the limiting block 504 is slidably connected to the inner wall of the rectangular groove 502. A connecting piece 506 is fixedly connected to the long arm end of the limiting block 504. Limiting rods 510 are fixedly connected to both sides of the lower mold base 2 at positions corresponding to the concave plate 501. The system achieves the goal of allowing for quick installation and disassembly of the lower mold base 2 using the limiting device 5, thus saving installation and disassembly time and increasing work efficiency. A pull ring 507 is fixedly connected to the side of the connecting piece 506 away from the limiting block 504. The pull ring 507 has a semi-circular cross-section. This allows the limiting block 504 to be pulled using the pull ring 507, making operation simpler and more convenient. Both ends of the rotating rod 503 are fitted with coil springs 508, with each end of the coil spring 508 fixedly connected to the concave plate 501 and the rod head 509, respectively. This ensures that when the limiting block 504 is rotated, the coil spring 508 generates a torsional force, and when the limiting block 504 is released, the torsional force of the coil spring 508 causes the limiting block 504 to automatically reset.

[0035] The working principle of the multi-angle bending forming mold provided by this utility model is as follows: When it is necessary to bend the workpiece, the angle between the two adjusting plates 408 needs to be adjusted according to the required bending angle. First, the motor 414 needs to be started, and then the output end of the motor 414 will drive the screw 401 to rotate between the side template 3 and the support plate 409. The threads at both ends of the screw 401 in opposite directions synchronously drive the two adjusting blocks 402 to slide horizontally towards each other along the axis of the screw 401 in the bottom groove 417. When the adjusting blocks 402 move, they pull the connecting buttons 403 on both sides to move synchronously, and the connecting buttons 403 push the connecting plate 404 to deflect. The other end of the connecting plate 404 acts on the round button 407 of the mounting block 405, which drives the mounting block 405 to make the adjusting plate 408 rotate around the adjusting rod 411 with the help of the ring rod 412. The mounting block 405 drives the adjusting plate 408 to rotate synchronously, and the ring rod 412 at the bottom of the adjusting plate 408 rolls along the surface of the adjusting rod 411. When the adjusting plate 408 rotates to the target angle, the motor 414 is turned off. At this time, the workpiece is placed on the surface of the two adjusting plates 408, and the rubber strips 418 on the surface of the adjusting plates 408 increase the friction with the workpiece to prevent slippage. During the bending operation, the upper die presses down, and the workpiece is deformed by being pressed down within the V-shaped angle formed by the adjusting plates 408. When it is necessary to change the bending angle, the motor 414 is restarted: if the motor 414 rotates forward, the screw 401 drives the two adjusting blocks 402 to move towards each other, and the connecting plate 404 pushes the mounting block 405 to increase the opening angle of the adjusting plate 408; if the motor 414 rotates in reverse, the screw 401 pulls the adjusting blocks 402 to move away from each other, and the connecting plate 404 pulls the mounting block 405 to decrease the opening angle of the adjusting plate 408. Throughout the entire process of the angle change of the adjusting plate 408, the ring rod 412 always rolls adaptively along the adjusting rod 411 to ensure rotational stability. A protective cover 415 covers the surface of the motor 414, and the heat generated by the motor 414 during operation is dissipated through the heat dissipation holes 416 on the arc surface of the protective cover 415. The entire adjustment process is driven by the motor 414 to provide bidirectional rotational power to the screw 401. The screw 401 and the adjusting block 402 engage to generate symmetrical linear motion. The connecting plate 404 converts the linear displacement into the rotational motion of the adjusting plate 408. The rolling engagement between the ring rod 412 and the adjusting rod 411 maintains the stability of the angle. The rubber strip 418 provides anti-slip friction when the workpiece contacts the rubber strip.

[0036] When the lower mold base 2 needs to be installed, firstly, when the lower mold base 2 is placed on the worktable 1, the limiting rods 510 on both sides of the lower mold base 2 contact the inclined surface of the short arm end of the limiting block 504. The guiding effect of the inclined surface forces the limiting block 504 to rotate and avoid it. When the limiting block 504 rotates, it will drive the rotating rod 503 to rotate together. At the same time, the rotating rod 503 will also drive the rod heads 509 at both ends to rotate. When the rod heads 509 rotate, they will twist the coil springs 508 at both ends of the rotating rod 503, thereby generating a torsional force. When the limiting rod 510 slides over the inclined surface and reaches below the short arm end of the limiting block 504, the coil spring 508 releases the torsional force and drives the rod heads 509 to rotate in the opposite direction. The rod heads 509 drive the limiting block 504 to rotate in the opposite direction through the rotating rod 503 to reset. When it is necessary to disassemble the lower mold base 2, the pull ring 507 is pulled to rotate the connecting piece 506 away from the limit rod 510, forcing the limit block 504 to rotate along with it. The coil spring 508 drives the rod head 509 to rotate through the rotating rod 503, thereby generating torsional force again. When the short arm end of the limit block 504 rotates to the point where it can no longer block the upward movement of the limit rod 510, the lower mold base 2 can be removed. The entire locking process is achieved by pulling the pull ring 507 to drive the limit block 504 to rotate, and by the automatic reset of the coil spring 508 to limit the limit groove 505 to the limit rod 510. To unlock, the operation is reversed. The pull ring 507 makes the operation of pulling the limit block 504 during disassembly simpler and more convenient.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
