Description

Technical Field

[0001] This utility model belongs to the field of edge banding production technology, specifically, it relates to a high wear-resistant polyethylene edge banding mold. Background Technology

[0002] Edge banding is a decorative material used on the edges of wooden furniture and boards, primarily serving a protective and aesthetic purpose. Polyethylene edge banding is made primarily of polyethylene, which has a high density, resulting in excellent wear resistance and heat resistance. This type of edge banding effectively prevents moisture from penetrating the board, helps prevent the release of harmful gases (such as formaldehyde) from within the board, and also reinforces the board, provides sound insulation, fire resistance, and heat insulation. Its surface is typically smooth, with moderate gloss, uniform thickness, and can present a texture and color close to natural wood.

[0003] Patent CN222858701U discloses an edge banding strip extrusion mold, which includes an upper mold and a lower mold. The upper mold is connected to the lower mold through a moving mechanism. A mold core assembly is clamped between the upper mold and the lower mold. A handwheel drives a lead screw to rotate, which drives a slider threaded to the outer wall of the lead screw to move the clamping plate at its bottom end below the slide groove to clamp the mold core assembly. The moving mechanism then adjusts the position of the lower mold to clamp and fix the mold core assembly at the bottom end. This allows the clamping space to be adjusted according to different sizes of mold core assemblies, improving the overall compatibility of the mold and facilitating the disassembly and cleaning of the mold core assembly.

[0004] Different specifications of edge banding strips require different specifications of molds. However, in the above technical solution, the replacement of the mold core components is cumbersome when producing different batches of edge banding strips, resulting in a lot of time spent on the preparatory process for edge banding strip production. This cannot further meet the demand for high-efficiency edge banding strip processing and has certain limitations. Utility Model Content

[0005] To address the technical problem in existing edge banding production where cumbersome mold core replacement leads to long preparation times and reduced processing efficiency, this utility model provides a high-wear-resistant polyethylene edge banding mold.

[0006] The objective of this utility model can be achieved through the following technical solutions: A high wear-resistant polyethylene edge banding mold includes an extruder; it also includes a turntable embedded in the feed channel port of the extruder via a rotating shaft; the turntable has three or six circumferentially arrayed through slots; the extruder has two feed ports corresponding to the feed channel; each through slot is provided with a mold core assembly, and the mold core assembly includes an upper mold and a lower mold, as well as an extrusion port that is opened together after the upper mold and the lower mold are attached.

[0007] Furthermore, the mold core assembly also includes fixing blocks that are respectively fixed to the upper mold and the lower mold. The fixing blocks are embedded inside the turntable and are fixed to the turntable by countersunk nails.

[0008] Furthermore, the two feed ports are arranged at 90°, and the two feed ports are located in the horizontal and vertical directions, respectively.

[0009] Furthermore, six through slots are provided, and the angle between each pair of adjacent mold core components is 60°.

[0010] Furthermore, three through slots are provided, and the angle between each pair of adjacent mold core components is 120°.

[0011] Furthermore, a friction ring is provided on the outer surface of the turntable.

[0012] Furthermore, the extruder has a lower pressure plate positioned next to the turntable; a threaded rod is fixedly connected to the center of the lower pressure plate; an upper pressure plate is fitted onto the threaded rod above the friction ring; a nut is threaded onto the threaded rod, and the nut is located above the upper pressure plate.

[0013] Furthermore, both the lower surface of the upper pressure plate and the upper surface of the lower pressure plate are provided with anti-slip textures.

[0014] The beneficial effects of this utility model are: 1. When producing edge banding strips of different specifications, the operator only needs to loosen the nuts, release the upper and lower pressure plates from fixing the turntable, rotate the turntable, replace and adjust the appropriate mold core assembly, align it with the appropriate feed port, and repeat the above steps to fix the turntable. The operation is simple, convenient and quick, which improves production efficiency and solves the technical problem in the prior art that the production of edge banding strips is cumbersome due to the mold core replacement, resulting in long preparation time and reduced processing efficiency, thus increasing its practicality.

[0015] 2. In this utility model, the two feed ports are arranged at 90°. Since the angle between two adjacent mold core components is 60°, when the turntable is rotated to connect one extrusion port with one feed port, the other extrusion ports will not connect with the other feed port, preventing simultaneous discharge from both feed ports. Furthermore, because the two feed ports are located vertically and horizontally respectively, operators can change the feed ports to extrude the sealing strip vertically or horizontally, facilitating subsequent cooling and winding of the sealing strip, and adapting to different working conditions.

[0016] 3. The mold core components in this utility model are all detachably mounted on the turntable end face. When none of the mold core components on the turntable are suitable, a suitable mold core component can be removed and replaced. In addition, when the mold core component is damaged and needs to be repaired or replaced, the countersunk pin can be removed directly, which is convenient and quick. At the same time, the mold core component includes an upper mold and a lower mold. During the production of polyethylene edge banding strips, there will be residual material in the upper mold and the lower mold. The detachable design allows the mold to be disassembled for better cleaning.

[0017] 4. This utility model uses the structure of upper and lower pressure plates and friction ring plates to fix the turntable. When it is necessary to release the fixation of the turntable, simply loosen the nut, which is convenient and quick. The lower surface of the upper pressure plate and the upper surface of the lower pressure plate are provided with anti-slip texture, which can significantly increase the static friction with the friction ring plate and effectively prevent relative sliding or loosening that may occur due to vibration or load changes during equipment operation, thereby ensuring the smoothness and reliability of transmission.

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.

[0020] Please see Figure 1 - Figure 4 As shown, a high wear-resistant polyethylene edge banding mold includes an extruder 1 and a turntable 10; the turntable 10 is embedded in the feed channel 7 port of the extruder 1 via a rotating shaft 5; the extruder 1 has two feed ports 8 corresponding to the position of the feed channel 7, the feed ports 8 are rectangular in structure, the two feed ports 8 are arranged at 90°, and the two feed ports 8 are located in the vertical direction and the horizontal direction respectively, for conveying the material for making polyethylene edge banding.

[0021] Please see Figure 3 and Figures 5-6 As shown, three or six through slots 11 are arranged in a circular array on the end face of the turntable 10 (six are provided in this embodiment). The through slots 11 are rectangular in shape. A mold core assembly 4 is detachably installed in each through slot 11. The mold core assembly 4 includes an upper mold 41 and a lower mold 42, and an extrusion port 43 that is opened together after the upper mold 41 and the lower mold 42 are attached. The size of the extrusion port 43 of the mold core assembly 4 is different. When there are six through slots 11, the angle between two adjacent mold core assemblies 4 is 60°. When there are three through slots 11, the angle between two adjacent mold core assemblies 4 is 120°. An integrally formed fixing block 44 is provided on both sides of the mold core assembly 4. The fixing block 44 is embedded in the turntable 10 and fixed to the turntable 10 by countersunk nails.

[0022] Please see Figure 1 and Figure 7 As shown, a friction ring plate 2 is provided on the outer surface of the turntable 10; a lower pressure plate 3 is provided on the side of the extruder 1 corresponding to the turntable 10, and the lower pressure plate 3 has a circular structure; a threaded rod 12 is fixedly connected to the center of the lower pressure plate 3; an upper pressure plate 9 is sleeved on the threaded rod 12 above the friction ring plate 2; a nut is threaded onto the threaded rod 12, and the nut is located above the upper pressure plate 9 for adjusting the position of the upper pressure plate 9; anti-slip textures 6 are provided on the lower surface of the upper pressure plate 9 and the upper surface of the lower pressure plate 3, and the anti-slip textures 6 are used to increase the friction between the upper and lower pressure plates 3 and the friction ring plate 2.

[0023] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below: In practical use, the operator first places commonly used die core components 4 with different extrusion nozzle diameters 43 into the through groove 11 of the turntable 10, and then uses countersunk screws to fix the die core components 4 to the end face of the turntable 10, completing the installation of the die core components 4; next, the operator manually rotates the turntable 10 to rotate the appropriate die core components 4 to the appropriate feed port 8, so that the extrusion nozzle 43 of the die core components 4 is connected to the feed port 8, which facilitates the production of the edge sealing strip and completes the adjustment of the die core components 4; finally, after adjusting the position of the die core components 4, the position of the friction ring 2 is fixed by using the threaded rod 12, nut, upper pressure plate 9 and lower pressure plate 3, thereby fixing the position of the turntable 10, completing the final preparation work for the production of polyethylene edge sealing strips; then, material is fed into the feed channel 7 of the extruder, and the production of polyethylene edge sealing strips can begin.

[0024] When producing edge banding strips of different specifications, operators only need to loosen the nuts, release the upper and lower pressure plates 3 from fixing the turntable 10, rotate the turntable 10, replace and adjust the appropriate mold core assembly 4, align it with the appropriate feed port 8, and repeat the above steps to fix the turntable 10. The operation is simple, convenient and quick, improving production efficiency. It solves the technical problem in the existing technology that when producing different batches of edge banding strips, the replacement of the mold core assembly 4 is cumbersome, resulting in a lot of time spent on the pre-production preparation process of edge banding strip production, which cannot further meet the needs of high-efficiency edge banding strip processing, thus increasing practicality.

[0025] Furthermore, in this invention, the two feed ports 8 are arranged at 90°. Since the angle between two adjacent mold core components 4 is 60°, when the turntable 10 is rotated to connect one extrusion port 43 with one feed port 8, the other extrusion ports 43 will not connect with the other feed port 8, preventing simultaneous discharge from both feed ports 8. Because the two feed ports 8 are located vertically and horizontally respectively, operators can change the feed ports 8 to extrude the sealing strip vertically or horizontally, facilitating subsequent cooling and winding of the sealing strip, adapting to different working conditions.

[0026] Furthermore, the mold core components 4 in this utility model are all detachably mounted on the end face of the turntable 10. When none of the mold core components 4 on the turntable 10 are suitable, a suitable mold core component 4 can be removed and replaced. In addition, when the mold core component 4 is damaged and needs to be repaired or replaced, the countersunk pin can be removed directly, which is convenient and quick. At the same time, the mold core component 4 includes an upper mold 41 and a lower mold 42. During the production of polyethylene edge banding strips, there will be residual material in the mold. The detachable design allows the mold to be disassembled for better cleaning.

[0027] Furthermore, this utility model utilizes the structure of upper and lower pressure plates 3 and friction ring plate 2 to fix the turntable 10. When it is necessary to release the fixation of the turntable 10, simply loosen the nut, which is convenient and quick. The lower surface of the upper pressure plate 9 and the upper surface of the lower pressure plate 3 are provided with anti-slip textures 6, which can significantly increase the static friction with the friction ring plate 2, effectively preventing relative sliding or loosening that may occur due to vibration or load changes during equipment operation, thereby ensuring the smoothness and reliability of transmission.
