Detailed implementation manners

[0021] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: A mold orifice chamfering tool that is easy to install and disassemble, the mold orifice chamfering tool that is easy to install and disassemble includes: a base 1, a limit hole 3 is opened on the base 1, and a rotating rod 4 is arranged on the base 1; an upper mounting seat 2, and an installation groove 5 is opened on the upper mounting seat 2;

[0024] During specific use, align the clamping block 15 fixedly connected to the cutting tool 16 with the installation groove 5 opened on the upper mounting seat 2 and snap it in, then align the convex block fixedly connected to the lower rotating handle 18 with the installation groove 5 and snap it in. Thread the fastening nut 19 with the threaded rod fixedly connected to the upper end of the upper mounting seat 2, so that the lower surface of the fastening nut 19 just closely adheres to the upper surface of the convex block fixedly connected to the lower rotating handle 18, and fix the cutting tool 16 and the lower rotating handle 18 on the upper mounting seat 2, then the device can be used to chamfer the mold orifice.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, a rotating rod 4 is provided to improve the adaptability of the device. The lower end of the rotating rod 4 is provided with threads, and the threaded part of the rotating rod 4 is in threaded connection with the threaded hole opened on the base 1. The lower end of the rotating rod 4 penetrates through the hole opened on the connecting disk 7 and is fixedly connected to the rotating disk 9. The upper end of the rotating rod 4 is provided with threads, and the rotating rod 4 penetrates through the hole opened on the upper mounting seat 2 and is in threaded connection with the threaded hole opened on the detachable handle 14. The upper mounting seat 2 is rotatably connected to the base 1. A lower rotating handle 18 is provided on the upper mounting seat 2. The staff inserts the base 1 into the hole opening, and rotates the detachable handle 14, so that the threaded part on the rotating rod 4 rotates along the threaded hole opened on the base 1, and the rotating disk 9 rotates accordingly. The limiting hole 3 is in a circular hole structure, and a limiting rod 6 is arranged in the limiting hole 3. The limiting rod 6 can slide up and down along the limiting hole 3. The bottom surface of the limiting rod 6 is fixedly connected to the upper surface of the connecting disk 7. As the threaded part on the rotating rod 4 rotates along the threaded hole opened on the base 1, the limiting rod 6 slides along the limiting hole 3, causing the connecting disk 7 to separate from the base 1. A rubber pad 12 is fixedly connected to the side of the moving block 11. One end of the moving block 11 is rotatably connected to one end of the connecting plate 10 through a shaft, and the other end of the connecting plate 10 is rotatably connected to the rotating disk 9 through a shaft. When the rubber pad 12 is squeezed against the inner wall of the hole opening, it will deform and increase the contact area with the inner wall of the hole opening, which can fix the connecting disk 7 and the base 1, facilitating the subsequent chamfering work. The rotating disk 9 is rotatably connected to the connecting disk 7. A limiting groove 8 is opened on the connecting disk 7. The limiting groove 8 is in a "convex" groove structure, and a limiting block 13 is arranged in the limiting groove 8. The limiting block 13 can move along the limiting groove 8. The limiting block 13 is fixedly connected to the moving block 11. As the rotating disk 9 rotates, combined with the fact that one end of the moving block 11 is rotatably connected to one end of the connecting plate 10 through a shaft, and the other end of the connecting plate 10 is rotatably connected to the rotating disk 9 through a shaft, it can drive the moving block 11 and the limiting block 13 to move along the limiting groove 8 opened on the connecting disk 7, so that the rubber pad 12 fixedly connected to the limiting block 13 is squeezed against the inner wall of the hole opening, fixing the connecting disk 7 and the base 1 in the die hole opening. The staff rotates the lower rotating handle 18 to rotate the upper mounting seat 2 and the cutting tool 16 to cut and chamfer the die hole opening, enabling the device to adapt to chamfering die hole openings of different sizes, facilitating the actual use of the staff, and improving the adaptability of the device.

[0027] Embodiment Three

[0028] On the basis of the second embodiment, a lower rotating handle 18 is provided for the convenience of the staff to perform post-maintenance on the device. The bump fixedly connected to the lower rotating handle 18 can be engaged into the installation groove 5 opened on the upper mounting seat 2. A fastening nut 19 is provided at the upper end of the upper mounting seat 2, and the fastening nut 19 is threadedly connected to the threaded rod fixedly connected to the upper end of the upper mounting seat 2. The staff twists and removes the fastening nut 19. The installation groove 5 is in a "convex"-shaped groove structure. A clamping block 15 is provided in the installation groove 5, and the clamping block 15 can slide along the installation groove 5. A fixing plate 17 is fixedly connected to the clamping block 15, and the clamping block 15 is fixedly connected to the inner side of the cutting knife 16. Then, the fixing plate 17 fixedly connected to the clamping block 15 can be pulled, and the cutting knife 16 and the clamping block 15 can be slid along the installation groove 5 and taken out. The staff can perform maintenance on it or replace the new cutting knife 16, improving the cutting effect of the device. The structure is simple, facilitating the installation and disassembly by the staff, facilitating the post-maintenance by the staff, and having high practicability.

[0029] During actual use, the base 1 is engaged into the orifice, so that the cutting knife 16 contacts the edge of the orifice on the mold. Rotate the detachable handle 14 to make the thread on the rotating rod 4 rotate along the threaded hole opened on the base 1, driving the rotating disk 9 to rotate in cooperation with the connecting plate 10. One end of the connecting plate 10 is rotatably connected to the moving block 11, and the other end of the connecting plate 10 is rotatably connected to the rotating disk 9 through a shaft, so that the moving block 11 and the limiting block 13 move along the limiting groove 8, and the rubber pad 12 fixedly connected to the limiting block 13 is extruded and deformed against the inner wall of the orifice, and then the connecting disk 7 and the base 1 can be fixed in the mold orifice. The upper mounting seat 2 is rotatably connected to the base 1. Rotate the lower rotating handle 18 to make the upper mounting seat 2 and the cutting knife 16 rotate, and chamfer the edge of the orifice on the mold. The above structures cooperate with each other, enabling the device to chamfer the edges of orifices with different specifications on the mold without replacing tools, improving the applicability of the device, facilitating the actual use by the staff, having high practicability, and the device being small and convenient for the staff to carry and use.
