[0002] Edge banding extrusion die is a mold equipment used to produce edge banding (also called edge banding, edge strip, seal, etc.). Edge banding is usually used for edge banding of furniture, cabinets, floors and other products, which can beautify the appearance of products and increase the durability and stability of products. This extrusion die is usually used to extrude thermoplastics through heating and pressure to form edge banding of the desired shape, with the characteristics of efficient and precise production.

[0003] At present, the existing edge banding extrusion dies need to be replaced during the production process because different specifications of edge banding require different specifications of dies. However, different specifications of dies have different sizes, which has limitations in the fixation of the dies, and it is not convenient to disassemble and clean the dies. Therefore, there is an urgent need for an edge banding extrusion die that is easy to disassemble and can adjust the fixing space according to the size of the die. Utility Model Content

[0022] The utility model is further described below in conjunction with the accompanying drawings:

[0023] like Figure 1-Figure 4 As shown, an edge banding extrusion die comprises: an upper die 1 and a lower die 2, the upper die 1 is connected to the lower die 2 by a moving mechanism, a core assembly 3 is clamped between the upper die 1 and the lower die 2, a slide groove 4 is provided on the bottom surface of the upper die 1, a slider is slidably installed inside the slide groove 4, a clamping plate 5 is fixedly connected to the bottom end of the slider, and a screw rod 6 is internally threadedly connected, and the end of the screw rod 6 is driven by a hand wheel. The utility model drives the screw rod 6 to rotate by the hand wheel to drive the slider threadedly connected to the outer wall of the screw rod 6 to drive the clamping plate 5 at its bottom end to move under the slide groove 4 to clamp the core assembly 3, and then adjust the position of the lower die 2 by the moving mechanism to clamp and fix it at the bottom end of the core assembly 3. This structure is combined together to adjust the clamping space according to the core assemblies 3 of different sizes, which can improve the overall compatibility of the mold and also facilitate the disassembly and cleaning of the core assembly 3.

[0024] In some embodiments, the moving mechanism includes a threaded rod 7 that passes through the upper mold 1 and the lower mold 2. The threaded rod 7 is threadedly connected to the lower mold 2. The function of the threaded rod 7 is to drive the lower mold 2 threadedly connected thereto to move up and down during rotation, and clamp and fix the core assembly 3 placed between the upper mold 1 and the lower mold 2. The threaded rod 7 is located on the outer wall of the top of the upper mold 1 and is fixed with a gear 8. The outer wall of the gear 8 is meshed with a rack 9. This structure meshes the rack 9 with the outside of the gear 8. By pulling the rack 9, the gear 8 is driven to rotate, thereby driving the threaded rod 7 to rotate, driving the lower mold 2 to rise and fall, and one rack 9 can drive two sets of gears 8 to rotate at the same time, thereby ensuring the synchronization of the rotation and avoiding the problem of the lower mold 2 being unable to move due to inconsistent rotation speeds caused by separate rotations.

[0025] In some embodiments, a limit bar 10 is fixedly installed on the top surface of the upper mold 1, and the distance between the limit bar 10 and the gear 8 meets the width of the rack 9. This setting can limit the rack 9 to prevent the rack 9 from losing contact with the output wheel during the pulling process, resulting in the inability to drive the gear 8 to rotate.

[0026] In some embodiments, the end of the upper mold 1 away from the gear 8 passes through a limiting column 11, and the limiting column 11 can slide through the lower mold 2. The setting of the limiting column 11 can serve as a limiting guide for the lower mold 2 to prevent the lower mold 2 from rotating off the threaded rod 7 during the process of being driven by the threaded rod 7 to be lifted and lowered. At the same time, the limiting column 11 can also limit the splint 5 to prevent the splint 5 from escaping the slide groove 4 along with the slider.

[0027] In some embodiments, the core assembly 3 is composed of two groups of symmetrical square modules 12, wherein the mating surface of one group of square modules 12 is fixedly installed with an insert block 13, and the mating surface of the other group of square modules 12 is provided with a slot that matches the insert block 13. The setting of the insert block 13 and the slot can achieve accurate docking when the square modules 12 are assembled, thereby avoiding position deviation during assembly.

[0028] In some embodiments, the outer wall of the upper mold 1 through which the screw rod 6 passes is a smooth outer wall. Such a configuration can prevent the upper mold 1 from rotating with the threaded rod 7. The outer wall of the slide groove 4 through which the screw rod 6 passes is a threaded outer wall, which is used to drive the slider threadedly connected to it to move, thereby driving the clamping plate 5 to clamp the core assembly 3. The screw rod 6 passes through the outer wall of the upper mold 1 and a limit block 14 is fixedly installed. The limit block 14 can be rotatably installed inside the upper mold 1. The function of the limit block 14 is to limit the position of the screw rod 6 to prevent the screw rod 6 from being displaced during rotation, affecting the movement of the clamping plate 5. At the same time, the limit block 14 can rotate inside the upper mold 1 without affecting the rotation of the screw rod 6.

[0029] Working principle: When in use, place the core assembly 3 between the upper mold 1 and the lower mold 2, turn the handwheel to drive the screw 6 to rotate, drive the slider threadedly connected to the outer wall of the screw 6 to move inside the slide groove 4, and drive the clamping plate 5 fixedly installed at the bottom end of the slider to move toward the core assembly 3 until the core assembly 3 is clamped. After clamping, place the rack 9 between the limit bar 10 and the gear 8 and engage the gear 8 to pull the rack 9 to drive the gear 8 to rotate, drive the threaded rod 7 fixedly connected at the axis of the gear 8 to rotate, thereby driving the lower mold 2 threadedly connected to its outer wall to move upward until it is close to the bottom surface of the core assembly 3 to complete the clamping of the core assembly 3.

[0030] The lead screw, threaded rod, gear and rack are all universal standard parts or are known through conventional experimental methods, so they will not be described in detail here.

[0031] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
