Description

Technical Field

[0001] This utility model relates to the field of injection molding nozzle technology, specifically to an anti-clogging injection molding nozzle. Background Technology

[0002] Injection molding is a method of shaping industrial products. Nowadays, products are usually made using rubber injection molding and plastic injection molding. The product shape is mainly achieved through injection molding machines and molds. The injection nozzle of the injection molding machine is an important part of the injection molding machine. It is mainly responsible for injecting molten thermoplastic or thermosetting materials into the mold, and is an important part of the process.

[0003] After use, some injection molding material remains at the tip of the injection nozzle. Over time, this accumulation can cause blockages, affecting the normal operation of the equipment. This requires staff to clean the nozzle, which takes up a lot of time. Utility Model Content

[0004] To address the issue that some injection molding material remains at the tip of the injection nozzle after use, accumulating over time and easily causing blockage, the purpose of this invention is to provide an anti-clogging injection nozzle.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an anti-clogging injection nozzle, comprising an injection nozzle body, a first rotating shaft rotatably mounted on one side of the lower part of the injection nozzle body, a worm gear fixedly mounted on one side of the first rotating shaft, a worm provided on one side of the worm gear, the worm and the worm gear meshing with each other, a drive assembly provided at the top of the worm, a first bevel gear fixedly mounted on the end of the first rotating shaft away from the worm gear, a second bevel gear provided at the lower part of the first bevel gear, the second bevel gear meshing with the first bevel gear, a second rotating shaft fixedly mounted in the middle of the second bevel gear, and a plurality of first scrapers arranged in a ring array fixedly mounted on the lower part of the second rotating shaft, the outer sides of the plurality of first scrapers contacting the lower inner wall of the injection nozzle body.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Example: Figure 1-3As shown, this utility model provides an anti-clogging injection nozzle, including an injection nozzle body 1. A first rotating shaft 24 is rotatably mounted on one side of the lower part of the injection nozzle body 1. A worm gear 23 is fixedly mounted on one side of the first rotating shaft 24. A worm 22 is provided on one side of the worm gear 23. The worm 22 and the worm gear 23 are meshed and connected. A drive assembly is provided at the top of the worm 22. By setting the worm gear 23 and the worm 22, wherein the structure of the worm gear 23 and the worm 22 has a self-locking function, the structure is made more stable, preventing the first rotating shaft 24 from being driven by excessive pressure during injection. The rotation of a scraper 271 affects its injection molding efficiency. A first bevel gear 25 is fixedly installed at the end of the first rotating shaft 24 away from the worm gear 23. A second bevel gear 26 is provided at the lower part of the first bevel gear 25. The second bevel gear 26 meshes with the first bevel gear 25. A second rotating shaft 27 is fixedly installed in the middle of the second bevel gear 26. A plurality of first scrapers 271 distributed in a ring array are fixedly installed at the lower part of the second rotating shaft 27. The outer sides of the plurality of first scrapers 271 are in contact with the lower inner wall of the injection nozzle body 1.

[0017] A filter plate 29 is fixedly installed in the middle of the injection nozzle body 1. The upper part of the filter plate 29 has a plurality of evenly distributed filter holes 292. The upper part of the second rotating shaft 27 is rotatably installed in the middle of the filter plate 29. A plurality of second scrapers 291 arranged in a ring array are fixedly installed in the upper part of the filter plate 29. The bottom end of the second scraper 291 is in contact with the top end of the filter plate 29.

[0018] A protective cover 28 is fixedly installed on the lower part of the injection nozzle body 1. The protective cover 28 is rotatably installed on the middle part of the second rotating shaft 27. The middle part of the first rotating shaft 24 is rotatably installed on the middle of one side of the protective cover 28. By setting the protective cover 28, the first bevel gear 25 and the second bevel gear 26 are installed inside the protective cover 28, and the second rotating shaft 27 is more stable when rotating.

[0019] A housing 21 is fixedly installed on one side of the lower part of the injection nozzle body 1. The middle part of one side of the worm gear 23 is fixedly installed inside the housing 21. The worm 22 is rotatably installed inside the housing 21. By setting the housing 21, it is convenient to install and protect the worm gear 23 and the worm 22, thereby increasing their service life.

[0020] The drive assembly includes a motor 2, which is fixedly mounted on one side of the top of the housing 21. The top of the worm 22 is fixedly mounted on the drive end of the motor 2. By setting the motor 2, the worm 22 can be driven to rotate under the drive of the motor 2, thereby driving the meshing worm wheel 23 to rotate.

[0021] A number of heating wires 11 are installed at the lower part of the injection nozzle body 1. By setting the heating wires 11, the end of the injection nozzle body 1 can be heated under the operation of the heating wires 11, and the material condensed at the end can be heated, thereby making it convenient to remove the material condensed at the end.

[0022] Working principle: In actual use, when the end of the injection nozzle body 1 is blocked, the heating wire 11 heats it to help the cooled injection molding material melt. At the same time, the motor 2 is started. Under the drive of the motor 2, the worm gear 22 is rotated, which in turn drives the worm wheel 23 to rotate, which in turn drives the first rotating shaft 24 to rotate. The rotation of the first rotating shaft 24 drives the first bevel gear 25 to rotate, which in turn drives the second bevel gear 26 that meshes with it to rotate, which in turn drives the second rotating shaft 27 to rotate, which in turn drives the first scraper 271 to rotate. This causes the blocked injection molding material inside to move and break it up, so that it can melt easily and the blockage can be quickly discharged.

[0023] The filter plate 29 can filter the raw materials during injection molding to prevent large pieces of raw materials from entering the end of the injection nozzle body 1 and causing blockage. When the second rotating shaft 27 rotates, it can drive the second scraper 291 to rotate. The internal temperature and the scraping action of the second scraper 291 melt the large pieces of raw materials and allow them to be discharged through the filter hole 292.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
