Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold cleaning technology, and in particular to a cleaning device for injection molding machine molds. Background Technology
[0002] A cleaning device for injection molding machine molds is a specialized piece of equipment or system designed for cleaning and maintaining injection molding machine molds. During the injection molding process, impurities such as molten plastic, mold release agent, and oil residue can remain on and inside the mold. Long-term accumulation of these impurities not only affects product molding quality and reduces mold lifespan but also leads to decreased production efficiency.
[0003] Cleaning injection molding molds is typically done manually. During the cleaning process, workers can observe the mold's condition, assess the nature of the dirt and the difficulty of cleaning, and take appropriate measures. Based on the mold's usage and past production experience, workers can accurately identify areas prone to dirt accumulation or damage and perform more thorough and meticulous cleaning and inspection. This helps to promptly identify and resolve potential problems, extending the mold's lifespan.
[0004] While manual cleaning of injection molding machine molds allows for immediate assessment, prolonged mold cleaning requires workers to perform repetitive actions such as bending over and reaching, which can easily lead to fatigue and negatively impact their health, resulting in inconsistent cleaning quality. Variations in cleaning skills and experience among workers also contribute to inconsistent cleaning results. Even for the same worker, cleaning effectiveness can vary depending on the time and conditions, making it difficult to guarantee consistently high-quality results. Therefore, a mold cleaning device for injection molding machines is proposed to address these issues. Utility Model Content

[0034] 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.
[0035] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides a cleaning device for injection molding machine molds, including a workbench 1 and two connecting plates 10. Two lifting components are provided at both ends of the workbench 1. Left and right moving components are provided on the sides of the two connecting plates 10. Shrinking components are provided on the sides of the two connecting plates 10. A sliding rod 16 is fixedly connected to the side of the connecting plate 10. A fixed frame 9 is slidably connected to the inner side of the sliding rod 16. A cleaning wheel assembly is provided inside the fixed frame 9. A liquid collection tank 13 is opened inside the workbench 1. A circulating spray assembly is provided on the inner side of the end of the liquid collection tank 13. A cleaning groove 21 is opened inside the workbench 1. Multiple positioning components are provided inside the cleaning groove 21.
[0036] The circulating spray assembly includes a circulating pipe 7, with its ends fixedly connected to the inner sides of the workbench 1 and the collection tank 13. A water pump 6 is fixedly connected to the middle of the circulating pipe 7, and the water pump 6 is fixedly connected to the side of the workbench 1. Multiple nozzles 8 are fixedly connected to the ends of the circulating pipe 7, and the multiple nozzles 8 are located at the top of the cleaning tank 21. After the water pump 6 is started, it draws out the cleaning fluid from the collection tank 13 and transports it through the circulating pipe 7 to the multiple nozzles 8 located at the top of the cleaning tank 21. The nozzles 8 evenly spray the cleaning fluid onto the mold in the cleaning tank 21, rinsing the mold surface.
[0037] Reference Figure 1 , Figure 2 and Figure 3 The cleaning wheel assembly has brush wheels 12 rotatably connected to the inner sides of both ends of the fixing frame 9. A drive motor 15 is fixedly connected to the end of the fixing frame 9, and the brush wheels 12 are fixedly connected to the output end of the drive motor 15. After the drive motor 15 starts, its output end drives the brush wheels 12 to rotate. The rotating brush wheels 12 contact the mold surface, and the rotation of the brushes mechanically rubs the mold surface, effectively removing stubborn stains and impurities. The left-right moving assembly includes two pulleys 18, which are rotatably connected to both ends of the connecting plate 10. A drive motor 19 is fixedly connected to the side of the connecting plate 10, with one pulley 18 fixedly connected to the output end of the drive motor 19. A belt 17 is fitted around the outside of the two pulleys 18, and the end of the fixing frame 9 is fixedly connected to the outside of the belt 17. The drive motor 19 drives one pulley 18 to rotate, and since the belt 17 is fitted around the outside of the two pulleys 18, the other pulley 18 also rotates, and the belt 17 begins to operate. The end of the fixed frame 9 is fixedly connected to the outside of the belt 17, so that when the belt 17 rotates, it will drive the fixed frame 9 to move left and right along the slide bar 16, thereby adjusting the horizontal position of the brush wheel.
[0038] Reference Figure 1 , Figure 2 and Figure 6 The lifting assembly includes a lifting housing 5, which is fixedly connected to the inner side of the workbench 1. A toothed block plate 11 is slidably connected to the inner side of the lifting housing 5, and a worm gear 29 is rotatably connected to the inner side of the lifting housing 5. A fixed rod 26 is rotatably connected to the inner side of the end of the lifting housing 5. A worm wheel 27 and a gear 28 are fixedly connected to the outer side of the fixed rod 26. The worm wheel 27 is meshed with the outer side of the worm gear 29, and the gear 28 is meshed with the side of the toothed block plate 11. When the worm gear 29 rotates, it drives the worm wheel 27 to rotate because the worm gear 29 meshes with the worm wheel 27. Since the worm wheel 27 and the gear 28 are fixed on the same fixed rod 26, the gear 28 also rotates. Because the gear 28 meshes with the toothed block plate 11, the toothed block plate 11 slides up and down inside the lifting housing 5, thereby realizing the lifting and lowering of the cleaning device to accommodate molds of different heights.
[0039] Reference Figure 1 , Figure 2 and Figure 5The shrinking assembly includes a housing 3, which is fixedly connected to the side of a toothed plate 11. Two toothed plates 23 are slidably connected to the inside of the housing 3, with their ends fixedly connected to the side of a connecting plate 10. Two gears 24 are rotatably connected to the inside of the housing 3, meshing with each other. A drive motor 25 is fixedly connected to the side of the housing 3, with one gear 24 fixedly connected to its output end. Starting the drive motor 25 causes one gear 24 to rotate. Because the two gears 24 mesh, the other gear 24 will also rotate in the opposite direction. The two toothed plates 23 mesh with the two gears 24 respectively. Under the action of the rotating gears 24, the two toothed plates 23 slide relative to or in opposite directions within the housing 3, thereby causing the connecting plate 10 and the cleaning device to shrink or expand to adapt to molds of different widths.
[0040] Reference Figure 2 , Figure 4 and Figure 6 The positioning component includes a spring push rod 14, which is fixedly connected to the side of the cleaning groove 21. A fixing block 22 is fixedly connected to the end of the spring push rod 14. Through the elasticity of the spring push rod 14, an outward pushing force is applied to the fixing block 22, causing the fixing block 22 to press firmly against the mold surface. This prevents the mold from moving during subsequent cleaning, ensuring the accuracy and stability of the cleaning work. Two telescopic rods 4 are fixedly connected to the inner sides of both ends of the worktable 1. The ends of the telescopic rods 4 are fixedly connected to the sides of the two housings 3. When the housing 3 needs to be adjusted, the telescopic rods 4 can extend and retract with the movement of the housing 3, ensuring the stability of the housing 3 during movement and restricting the housing 3 to move only in specific directions, thus playing a role in auxiliary positioning. A hand crank 30 is rotatably connected to the inner side of the lifting housing 5, and the hand crank 30 is fixedly connected to the end of the worm gear 29. The operator rotates the hand crank 30 to drive the worm gear 29 to rotate. A filter screen 20 is fixedly connected to the inner side of the workbench 1. The filter screen 20 connects the inner sides of the liquid collection tank 13 and the cleaning tank 21. The filter screen 20 plays a filtering role, intercepting impurities in the cleaning fluid and ensuring that the cleaning fluid flowing back to the liquid collection tank 13 is relatively clean, thus realizing the recycling of the cleaning fluid. Multiple bases 2 are fixedly connected to the bottom of the workbench 1. The bases 2 are used to support the entire cleaning device, fixing the device to the ground and ensuring stability during operation.
[0041] Working principle: First, the injection molding mold is placed inside the cleaning groove 21. The cleaning groove 21 is equipped with multiple positioning components, which consist of a spring push rod 14 and a fixing soft block 22. The spring push rod 14 is compressed by the mold and then uses its own elasticity to press the fixing soft block 22 tightly against the mold surface, thereby fixing the mold firmly in the cleaning groove 21 and preventing the mold from moving during the cleaning process.
[0042] Then, after the water pump 6 is started, the cleaning solution in the collection tank 13 is transported to the nozzle 8 through the circulation pipe 7. The nozzle 8 sprays the cleaning solution onto the mold in the cleaning tank 21 to rinse the mold. After rinsing the mold, the cleaning solution flows back to the collection tank 13 through the filter screen 20, realizing the recycling of the cleaning solution.
[0043] After the lifting assembly, shrinking assembly, and left and right moving assembly are adjusted to the correct positions of the brush wheel 12, the drive motor 15 is started to drive the brush wheel 12 to rotate. The brush wheel 12 contacts the mold surface and mechanically cleans the mold surface through the rotating brush, removing stubborn stains and impurities from the mold surface.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
