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.

[0029] Reference Figures 2-4 This utility model provides an embodiment of a bending fork forming mold, comprising: a lower mold base 1; an upper mold base 2 fixedly connected to the top of the lower mold base 1; an electric push rod 3 mounted on the top of the upper mold base 2; a sliding plate 4 fixedly connected to the bottom of the electric push rod 3; four corners of the sliding plate 4 slidably connected to the outer wall of the upper mold base 2; first hydraulic rods 10 fixedly connected to the left and right ends of the bottom of the sliding plate 4; ring blades 8 fixedly connected to the bottom of the first hydraulic rods 10; a second hydraulic rod 12 rotatably connected inside the sliding plate 4; a punch 9 provided at the front end of the second hydraulic rod 12; the shape and dimensions of the outer wall of the punch 9 matching the shape and dimensions of the inner wall of the ring blade 8; a base 15 fixedly connected to the inner wall of the lower mold base 1; a motor 16 fixedly connected inside the base 15; a concave mold 5 provided at the top of the motor 16; the concave mold 5 mounted on the top of the base 15; and an adjusting disc 7 rotatably connected to the front end of the second hydraulic rod 12. The top of the adjusting disc 7 is rotatably connected to the inner wall of the slide plate 4. The bottom edge of the adjusting disc 7 is rotatably connected to the four sides of the first connecting rod 14. The bottom outer edge of the first connecting rod 14 is rotatably connected to the first sliding rod 11. The outer wall of the first sliding rod 11 is slidably connected to the inner wall of the bottom of the slide plate 4. The bottom of the first sliding rod 11 is fixedly connected to the first locking block 13. The shape and size of the outer end of the adjacent first locking block 13 are matched with the shape and size of the slot on the inner wall of the punch 9. The drive end of the motor 16 is fixedly connected to the rotating disc 17. The bottom of the rotating disc 17 is rotatably connected to the inner wall of the base 15. The top inner wall of the rotating disc 17 is slidably connected to the second sliding rod 18. The outer wall of the second sliding rod 18 is slidably connected to the top inner wall of the base 15. The top of the second sliding rod 18 is fixedly connected to the second locking block 19. The shape and size of the outer end of the adjacent second locking block 19 are matched with the shape and size of the slot on the bottom of the die 5.

[0030] Specifically, a controller is installed on the right side of the lower mold base 1. The controller can independently control the start and stop of the electric push rod 3, the first hydraulic rod 10, the second hydraulic rod 12, and the motor 16. When disassembling the die 5 and the punch 9, the controller is used to start the motor 16 and the second hydraulic rod 12, such as... Figure 5 As shown, the motor 16 will drive the rotating disk 17 to rotate clockwise, thereby causing the second slide rod 18 to retract. The second slide rod 18 will cause the second locking block 19 to retract inward and disengage from the inner wall of the die 5. Then the die 5 can be pulled out upward. Then the second hydraulic rod 12 will extend, thereby causing the adjusting disk 7 to rotate counterclockwise. Then, through the connecting action of the first connecting rod 14, the first slide rod 11 will retract inward and cause the first locking block 13 to disengage from the inner wall of the punch 9. At this time, the punch 9 will disengage under the action of gravity. At this time, both the die 5 and the punch 9 are disassembled.

[0031] Reference Figure 1 and Figure 6 The collecting hopper 6 is slidably connected to the inner walls of the left and right sides of the front end of the lower mold base 1. The collecting hopper 6 is set at the rear end of the adjusting block 22 and is slidably installed on the inner wall of the lower mold base 1. The rear end of the adjusting block 22 is rotatably connected to the second connecting rod 23. The top end of the second connecting rod 23 is rotatably connected to the limit block 24. The outer wall of the limit block 24 is slidably connected to the inner wall of the lower mold base 1. Several springs 20 are fixedly connected to the top end of the limit block 24. The other end of the springs 20 is fixedly connected to the top end of the inner wall of the lower mold base 1. The left and right ends of the collecting hopper 6 are fixedly connected to the buckles 21. The shape and size of the rear end of the buckles 21 are matched with the shape and size of the front end of the limit block 24.

[0032] Specifically, when the collecting hopper 6 is installed on the inner wall of the lower mold base 1, the buckle 21 will enter the lower mold base 1 and press against the inclined surface of the limiting block 24, thereby pushing the limiting block 24 upward and compressing the spring 20. After the buckle 21 is installed in place, it will disengage from the limiting block 24. At this time, the limiting block 24 will be pushed downward by the reverse action of the spring 20. At this time, a limiting effect will be formed between the limiting block 24 and the buckle 21. At this time, the collecting hopper 6 will be installed on the lower mold base 1 for collection.

[0033] Working principle: During use, the concave die 5 and the punch 9 are installed on the bending fork forming die. First, align the bottom of the concave die 5 with the guide protrusion on the base 15, then push it downwards, making the concave die 5 fit tightly against the base 15. At the same time, the second locking block 19 will enter the concave die 5. Then, use the controller to start the motor 16. The motor 16 will drive the rotating disk 17 to rotate. The rotation of the rotating disk 17 will drive the second sliding rod 18 to expand outwards, thereby driving the second locking block 19 to expand outwards and lock inside the concave die 5. At this time, the concave die 5 will be locked on the base 15. Then, the punch 9 is installed upwards along the inner wall of the ring blade 8. Then, the first locking block 13 will enter the punch 9. At this time, the second hydraulic rod 12 is activated to retract. The retraction of the second hydraulic rod 12 will drive the adjusting disk 7 to rotate. Through the connection of the first connecting rod 14, the first... The slide bar 11 expands outward, thereby locking the first locking block 13 into the inner wall of the punch 9. At this time, the punch 9 and the die 5 are firmly installed on the bending fork forming mold. Then, the electric push rod 3 is activated to bend the die. After the punch 9 and the die 5 come into contact, the first hydraulic rod 10 is activated. The first hydraulic rod 10 will drive the ring blade 8 to move downward, thereby cutting off the waste chips. The waste chips will enter the interior of the collecting hopper 6 through the through groove on the lower mold base 1. After the collecting hopper 6 is full, the adjusting blocks 22 on both sides are pushed inward, thereby driving the bottom of the second connecting rod 23 to slide inward, thereby causing the lateral length of the second connecting rod 23 to change to the longitudinal length, thereby driving the limiting block 24 to push upward. The limiting block 24 will disengage from the buckle 21, thereby releasing the collecting hopper 6. Then, the collecting hopper 6 can be pulled out using the handle to clean and process the waste chips.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
