Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an oiling device for injection mold maintenance. Background Technology

[0002] Injection molds are the most important molding equipment in injection molding product processing. Their quality directly affects the quality of the finished product. During use, injection molds are affected by various factors, such as corrosion of the injection material, wear from the mold's opening and closing motion, and blockage of the cooling system. These factors can lead to a decline in mold performance or even damage. Therefore, regular maintenance of injection molds is essential. Among these maintenance methods, oiling is a crucial part of injection mold care. It can effectively prevent rust and corrosion and extend the service life of the mold.

[0003] Currently, most methods involve manual application using tools. While this improves the accuracy of the application to some extent, allowing the oil to be distributed more evenly on the mold surface, its efficiency is relatively low. Furthermore, the evenness of the application largely depends on the operator's skill level.

[0004] To overcome the shortcomings of manual application, some factories have begun to try oil spraying for mold lubrication and maintenance. Although this method can quickly cover the mold surface with oil, the uncontrollable nature of oil spraying often leads to uneven oil distribution, with some areas having excess oil while others may not be adequately lubricated.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0023] 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.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an oiling device for injection mold maintenance, including a maintenance table 1, and a reciprocating distance adjustable mechanism is slidably installed on the inner wall of the maintenance table 1;

[0025] The reciprocating distance adjustable mechanism includes a fixed plate 6 slidably mounted on the inner wall of the maintenance table 1. A fixed ring 12 is fixedly mounted on the side wall of the fixed plate 6. A motor 5 is fixedly mounted on the side wall of the fixed ring 12. A screw 13 is fixedly mounted on the drive end of the motor 5. A threaded tube 23 is threadedly connected to the screw 13. A sleeve 22 is fixedly mounted on the side wall of the threaded tube 23. A rotating cylinder 15 is fitted inside the sleeve 22. An inclined plate 16 is fixedly mounted on the side wall of the rotating cylinder 15. A cross groove 17 is formed on the inner wall of the inclined plate 16. A screw 18 is threadedly connected to the inner wall of the cross groove 17. The rotating cylinder 15 is located away from the inclined plate 16. A turntable 20 is rotatably mounted on the inner side wall. A connecting hole 21 is opened on the surface of the turntable 20. A connecting column 24 is fixedly mounted on the inner wall of the connecting hole 21. A support rod 25 is fixedly mounted on the outer wall of the connecting column 24. A rotating column 26 is rotatably mounted on the bottom of the support rod 25. A connecting shaft 27 is slidably mounted on the outer wall of the rotating column 26. A sliding rod 29 is fixedly mounted on the outer wall of the connecting shaft 27. A sleeve 7 is slidably mounted on the outer wall of the sliding rod 29. A connecting rod 32 is fixedly mounted on the end of the sliding rod 29 away from the connecting shaft 27. A connecting plate 8 is fixedly mounted on the bottom end of the connecting rod 32. A first-stage telescopic rod 9 is fixedly mounted on the bottom of the connecting plate 8.

[0026] It should be noted that the left and right offset of the inclined plate 16 is adjusted by rotating the screw 18, thereby changing the tilt angle of the rotating drum 15, and thus adjusting the reciprocating stroke length of the coating ball 11 on the injection mold surface.

[0027] Please see Figure 3 This utility model provides a technical solution: an oiling device for injection mold maintenance, including an elastic telescopic mechanism fixedly installed on the inner side wall of a primary telescopic rod 9;

[0028] The elastic telescopic mechanism includes a rack 33 fixedly installed on the inner wall of the first-stage telescopic rod 9. The rack 33 is meshed with a gear 34. The side wall of the gear 34 is connected to the second-stage telescopic rod 35. A fixed plate 39 is fixedly installed on the top of the inner wall of the first-stage telescopic rod 9. A spring 40 is fixedly installed on the bottom of the fixed plate 39. The bottom end of the spring 40 is fixedly connected to the top of the outer wall of the second-stage telescopic rod 35.

[0029] It should be noted that when the bottom coating ball 11 encounters an uneven surface, the coating ball 11 moves upward to press the four-stage telescopic rod 37. At this time, the multi-stage telescopic rod gradually retracts upward under the rotation of the gear 34, so that the coating ball 11 can be finely adjusted according to the different shapes and sizes of the injection mold to ensure the oiling effect.

[0030] Please see Figure 3 This utility model provides a technical solution: an oiling device for injection mold maintenance, including a secondary telescopic rod 35 with a tertiary telescopic rod 36 slidably installed on the inner wall, a tertiary telescopic rod 37 with a tertiary telescopic rod 36 slidably installed on the inner wall, a screw 38 fixedly installed at the bottom of the tertiary telescopic rod 37, and elastic telescopic mechanisms also installed on the inner walls of the secondary telescopic rod 35 and the tertiary telescopic rod 36.

[0031] Please see Figure 4 This utility model provides a technical solution: an oiling device for injection mold maintenance, including a rotating shaft 41 rotatably mounted on the side wall of a gear 34, a support arm 42 fixedly mounted on the outer wall of the rotating shaft 41, and one end of the support arm 42 away from the rotating shaft 41 fixedly mounted on the side wall of a secondary telescopic rod 35.

[0032] It should be noted that this linkage mechanism makes the extension and retraction of the multi-stage telescopic rods more precise and controllable, avoiding uneven coating caused by the elasticity of the spring 40.

[0033] Please see Figure 1 This utility model provides a technical solution: an oiling device for injection mold maintenance, including a screw 19 threadedly connected to the inner wall of a rotating cylinder 15, the two ends of the screw 19 being threadedly connected to the inner wall of a sleeve 22, a slider 14 fixedly installed at the bottom of a fixing plate 6, and an electric telescopic rod provided on the side wall of the slider 14.

[0034] It should be noted that when the electric telescopic rod is working, it will push the slider 14 to move in the horizontal direction. Since the slider 14 is fixedly connected to the fixed plate 6, the fixed plate 6 and other components on it will also move accordingly.

[0035] Please see Figure 1 This utility model provides a technical solution: an oiling device for injection mold maintenance, including a connecting shaft 27 with a three-slide groove 28 on its inner wall, a rotating column 26 with its outer wall slidably mounted on the inner wall of the three-slide groove 28, a sleeve 7 with a four-slide groove 30 on its inner wall, the inner wall of the four-slide groove 30 being slidably connected to a slide rod 29, and a five-slide groove 31 at the bottom of the four-slide groove 30, the inner wall of the five-slide groove 31 being slidably connected to a connecting rod 32.

[0036] It should be noted that by opening sliding grooves inside the connecting shaft 27 and the sleeve 7 respectively, and slidingly installing the rotating column 26, the sliding rod 29 and the connecting rod 32 in these sliding grooves, a stable sliding connection structure can be formed, which can enhance the connection strength between the components, improve the stability of the overall structure, and make the mechanism more stable and reliable during operation.

[0037] Please see Figure 2 This utility model provides a technical solution: an oiling device for injection mold maintenance, including a screw threaded to a support plate 10, a Velcro strap at the bottom of the support plate 10, and an oiling ball 11 attached to the bottom of the support plate 10.

[0038] It should be noted that the paint ball 11 is attached to the bottom of the support plate 10 by Velcro. This connection method makes it very simple and quick to replace the paint ball 11. When the paint ball 11 is worn or needs to be replaced with a paint ball 11 of different material or color, the user only needs to gently peel off the old paint ball 11 and then attach the new one. There is no need for complicated disassembly and installation process.

[0039] Please see Figure 2 This utility model provides a technical solution: an oiling device for injection mold maintenance, including a maintenance platform 1 with a second groove 3 at the bottom of the inner wall, the inner wall of the second groove 3 being slidably connected to a slider 14, a first groove 2 on the inner side wall of the maintenance platform 1, the inner wall of the first groove 2 being slidably connected to a motor 5, a fixed platform 4 being fixedly installed at the bottom of the maintenance platform 1, and an integrally formed anti-slip texture on the top of the fixed platform 4.

[0040] It should be noted that the sliding connection design between the slide groove 2 3 and the slider 14 allows the relevant components to slide smoothly inside the maintenance table 1, which enhances the stability of the structure and improves the flexibility of the component movement.

[0041] Furthermore, the one-piece molded anti-slip texture on the top of the fixed platform 4 can increase the friction between the fixed platform 4 and the injection mold, preventing slippage or displacement during use.

[0042] Working principle: After the device is started, motor 5 starts working, driving screw 13 to rotate. Since screw 13 is threadedly connected to threaded tube 23, threaded tube 23 will move axially under the rotation of screw 13. A rotating cylinder 15 is fitted inside the sleeve 22 fixedly installed on the side wall of threaded tube 23. The rotating cylinder 15 is threadedly connected to screw 18 through the cross groove 17 on the inner wall of inclined plate 16. Therefore, when threaded tube 23 moves, it will drive the rotating cylinder 15 and its internal structure to move together. When it is necessary to adjust the reciprocating stroke, screw 18 is rotated first. Inclined plate 16 will be pushed and offset in the left and right directions. This offset of inclined plate 16 will directly cause the rotating cylinder 15 fixedly connected to it to tilt. A turntable 20 is rotatably installed on the inner wall of the side of rotating cylinder 15 away from inclined plate 16. Turntable 20 is fixedly connected to support rod 25 through connecting post 24 on the inner wall of connecting hole 21. When rotating cylinder 15 tilts, turntable 20 and support rod The support rod 25 will also move accordingly. The rotating column 26 at the bottom of the support rod 25 is slidably mounted on the outer wall of the rotating column 26. The slide rod 29 fixedly mounted on the outer wall of the connecting shaft 27 slides in the sleeve 7. As the rotating cylinder 15 moves, the rotation of the turntable 20 will drive the support rod 25, rotating column 26, connecting shaft 27 and slide rod 29 to reciprocate in the sleeve 7. The connecting rod 32 and connecting plate 8 fixedly mounted at the end of the slide rod 29 away from the connecting shaft 27 will move accordingly, thereby driving the first-stage telescopic rod 9 and the brush ball 11 below it to perform reciprocating oiling action on the surface of the injection mold. The rack 33 fixedly mounted on the inner wall of the first-stage telescopic rod 9 meshes with the gear 34. When the brush ball 11 at the bottom encounters an uneven surface, it presses the fourth-stage telescopic rod 37 upward. At this time, the multi-stage telescopic rod gradually retracts upward under the rotation of the gear 34, so that the brush ball 11 can be finely adjusted according to the different shapes and sizes of the injection mold to ensure the oiling effect.
