Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to an automatic lubrication device for precision molds. Background Technology

[0002] With the continuous development of global industry, various sectors are demanding increasingly higher precision, quality, and complexity in their products. Molds, as crucial process equipment in industrial production, enable efficient, high-volume, and high-precision production, meeting market demands for diverse products. In the mold processing field, traditional lubrication methods often rely on manual operation, which cannot provide lubrication in real-time based on the mold's working condition. This can lead to untimely lubrication, increasing the risk of mold wear. Therefore, the emergence of automatic lubrication devices has become an inevitable trend.

[0003] While current lubrication devices in mold processing equipment can deliver lubricant to the slide rails in a timely and measured manner, in actual use, as the slider continuously slides along the slide rails, these devices often fail to provide direct and effective lubrication to the internal contact points between the slider and the slide rails. This results in significant lubricant waste due to the inability to accurately deliver lubricant to critical contact areas, potentially increasing production costs. Therefore, a precision automatic mold lubrication device is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic lubrication device for precision molds, which aims to improve the problem that the existing technology cannot directly and effectively lubricate the internal contact area between the slider and the slideway.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic lubrication device for precision molds includes a base plate. Two support columns are fixedly connected to the top of the base plate. Slider blocks are slidably connected to the exterior of each support column. Support piles are fixedly connected to the interior of each slider. Telescopic blocks are slidably connected to the adjacent sides of each support pile. Telescopic springs are fixedly connected to the distant sides of each telescopic block. Liquid outlet pipes are slidably connected to the interior of each slider. Squeezing bladders are fixedly connected to the tops of each liquid outlet pipe. Support plates are fixedly connected to the tops of the two support columns. Two liquid inlet pipes are fixedly connected to the tops of the support plates. Lubricating machines are fixedly connected to the exterior of each of the two liquid inlet pipes. Quick-fixing fastening components are fixedly connected to both ends of each of the two lubricating machines. A forming mold is fixedly connected to the top of the base plate. A hydraulic cylinder is fixedly connected to the top of the support plate. A hydraulic block is fixedly connected to the bottom end of the hydraulic cylinder.

[0007] As a further description of the above technical solution:

[0008] Both sides of the hydraulic block are fixedly connected to connecting plates, and the far sides of the two connecting plates are fixedly connected to the near sides of the slider.

[0009] As a further description of the above technical solution:

[0010] A lubrication machine is fixedly connected to the top of the support plate, and two drainage grooves are provided inside the support plate;

[0011] As a further description of the above technical solution:

[0012] Both of the compression bladders are provided with injection ports at their top ends, and both of the support piles are sleeved inside the first telescopic spring.

[0013] As a further description of the above technical solution:

[0014] The two telescopic springs are fixedly connected to the inner wall of the slider on opposite sides, and the two telescopic blocks are slidably connected to the inside of the slider on the outside.

[0015] As a further description of the above technical solution:

[0016] The fixing assembly includes two fixing rods, which are fixedly connected to the two sides of the lubrication machine on their adjacent sides. A support plate is fixedly connected to the rear end of the two fixing rods. A threaded column is slidably connected inside the support plate. A telescopic column is slidably connected inside the threaded column. A rotating ring is threadedly connected to the outside of the threaded column. Multiple connecting rods are fixedly connected to the front end of the threaded column. A fixing block is fixedly connected to the front end of the multiple connecting rods. A fixing ring is fixedly connected to the front end of the threaded column. A handle is fixedly connected to the rear end of the threaded column. A movable block is slidably connected to the outside of the telescopic column. Rotating rods are rotatably connected to all four sides of the movable block. A telescopic spring is sleeved on the outside of the telescopic column. A fixing column is fixedly connected to the top end of the telescopic column.

[0017] As a further description of the above technical solution:

[0018] The rear end of the second telescopic spring is fixedly connected to the front end of the movable block, and the front end of the second telescopic spring is fixedly connected to the rear end of the fixed column.

[0019] As a further description of the above technical solution:

[0020] The fixed column is slidably connected inside the fixed block, and the threaded column has multiple grooves on its outside, with the rotating rod slidably connected inside the grooves.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the slider squeezes the compression bladder, causing the internal lubricant to be injected into the internal hole of the slider from the outlet pipe. The telescopic block inside the slider will automatically close. When the slider slides on the support rod, the lubricant will slide along with it, so that the lubricant is evenly coated on the support rod and the slider. The telescopic block avoids the waste of lubricant and improves the lubrication efficiency and the mold processing accuracy.

[0023] 2. This utility model cleverly utilizes the storage and unfolding functions of the rotating rod, the rotation fixing and loosening mechanism of the rotating ring, and the controllable telescopic characteristics of the telescopic column. When the lubrication machine body needs to be installed, the quick-fixing component is slid into the fixed position. During this process, the rotating rod will retract according to the compression of the opening or by manually pushing the telescopic column, making the installation process smoother. Maintenance or replacement of the lubrication machine can be completed in a short time. At the same time, it also improves the overall operating efficiency of the mold processing device, ensuring the continuity and stability of production. Attached Figure Description

[0030] 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.

[0031] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic lubrication device for precision molds, comprising a base plate 1 made of high-strength metal, providing stable support for the entire device and ensuring no shaking during mold processing. Two support columns 2 are fixedly connected to the top of the base plate 1. These support columns 2 are made of wear-resistant alloy steel, capable of withstanding the friction caused by frequent sliding of the slider 3, thus extending their service life. Slider 3s are slidably connected to the outside of each support column 2. The surfaces of the slider 3s are specially treated to have a low coefficient of friction, making sliding on the support columns 2 smoother. Support posts 5 are fixedly connected inside each slider 3. Telescopic blocks 7 are slidably connected to the adjacent sides of the two support posts 5, and telescopic springs 6 are fixedly connected to the distant sides of the two telescopic blocks 7. The telescopic springs 6 have a high elastic coefficient, enabling them to quickly push the telescopic blocks 7 to automatically close during the sliding of the slider 3, preventing lubricant leakage.

[0032] Both sliders 3 are internally connected to outlet pipes 4. Sliding holes are provided inside the sliders 3, and the outlet pipes 4 slide within these holes. An opening at the bottom of each hole allows the lubricant to contact the support column 2. The outlet pipes 4 are made of corrosion-resistant material to ensure the lubricant is not affected by corrosion during transport. Squeezing bladders 9 are fixedly connected to the top of each outlet pipe 4. These bladders are made of highly elastic rubber and can stably output lubricant under pressure. Support plates 27 are fixedly connected to the top of each support column 2. These support plates 27 are made of sturdy metal sheet and can withstand the weight and pressure of the equipment above. Two inlet pipes 12 are fixedly connected to the top of the support plate 27. These inlet pipes 12 have good sealing properties to prevent lubricant leakage. Lubricating machines 13 are fixedly connected to the outside of each inlet pipe 12. These lubricating machines 13 can stably output lubricant, ensuring automatic lubrication of the mold.

[0033] Both lubrication machines 13 are fixedly connected to quick-fixing components. A forming mold 31 is fixedly connected to the top of the base plate 1. A hydraulic cylinder 28 is fixedly connected to the top of the support plate 27. A hydraulic block 29 is fixedly connected to the bottom of the hydraulic cylinder 28. Connecting plates 30 are fixedly connected to both sides of the hydraulic block 29. The far side of the two connecting plates 30 is fixedly connected to the near side of the slider 3. The lubrication machine 13 is fixedly connected to the top of the support plate 27. Two drainage grooves 11 are provided inside the support plate 27. The drainage grooves 11 can quickly guide the lubricant to the injection port 10, improving lubrication efficiency. The tops of the two compression bladders 9 are provided with injection ports 10. The outside of the two support piles 5 are both sleeved inside the telescopic springs 6. The far side of the two telescopic springs 6 are fixedly connected to the inner wall of the slider 3. The outside of the two telescopic blocks 7 are slidably connected to the inside of the slider 3.

[0034] Reference Figure 1 and Figure 4 One embodiment of this utility model provides: the fixing assembly includes two fixing rods 14, which are fixedly connected to the two sides of the lubrication machine 13 on their adjacent sides. The fixing rods 14 are made of sturdy metal material, providing stable support for the lubrication machine 13. Support plates 15 are fixedly connected to the rear ends of the two fixing rods 14. The support plates 15 are also made of sturdy metal plate, ensuring a firm connection with the fixing rods 14. A threaded post 18 is slidably connected inside the support plate 15. The surface of the threaded post 18 is finely threaded, ensuring that the rotating ring 19 can move smoothly on it. A telescopic post 21 is slidably connected inside the threaded post 18, and the rotating ring 19 is threadedly connected to the outside of the threaded post 18. The surface of the rotating ring 19 has an anti-slip texture, facilitating rotation by the operator.

[0035] Multiple connecting rods 17 are fixedly connected to the front end of the threaded column 18, and a fixing block 16 is fixedly connected to the front end of the multiple connecting rods 17. A fixing ring 22 is fixedly connected to the front end of the threaded column 18, and a handle 20 is fixedly connected to the rear end of the threaded column 18. A movable block 23 is slidably connected to the outside of the telescopic column 21. The movable block 23 can slide smoothly on the telescopic column 21 to control the rotating rod 24. Rotating rods 24 are rotatably connected to all four sides of the movable block 23. The front end of the rotating rod 24 is set to be arc-shaped. When it slides forward and touches an object, it will rotate downward, causing the movable block 23 to compress the telescopic spring 25 and slide forward until the rotating rod 24 fits into the groove 8.

[0036] The bottom of the rotating rod 24 is arc-shaped. When the rotating rod 24 moves backward under the thrust of the second telescopic spring 25, it slides upward after touching the fixed ring 22, thus opening up. The rotating rod 24 has a certain elasticity and strength, which can play a good supporting role during the fixing process. The telescopic column 21 is fitted with the second telescopic spring 25, which can provide a stable thrust for the rotating rod 24 to ensure a firm fixation. The top of the telescopic column 21 is fixedly connected to the fixed column 26. The rear end of the second telescopic spring 25 is fixedly connected to the front end of the movable block 23, and the front end of the second telescopic spring 25 is fixedly connected to the rear end of the fixed column 26. The fixed column 26 is slidably connected inside the fixed block 16. The threaded column 18 is provided with multiple grooves 8 on its exterior, and the exterior of multiple rotating rods 24 is slidably connected inside the multiple grooves 8.

[0037] Working principle: When the operator is using the mold for processing, when the hydraulic cylinder 28 is activated, the slider 3 will slide up and down with the handle 20 of the connecting plate 30 fixed on the hydraulic block 29. When the slider 3 slides to the top, the liquid outlet pipe 4 will slide into the interior of the slider 3 and push open the telescopic block 7, allowing the telescopic block 7 to slide into the interior of the slider 3. At the same time, the extrusion bladder 9 will be squeezed, causing the lubricating fluid inside to flow out from the liquid outlet pipe 4, which will lubricate the slider 3 and the support column 2. The lubrication machine 13 will output lubricating fluid through the liquid inlet pipe 12 and inject it into the extrusion bladder 9 through the drainage groove 11 and the injection port 10. The lubricating fluid is automatically injected through the extrusion of the mold. The lubrication of this part is crucial to ensure the smooth movement of the slider 3. Otherwise, problems such as jamming and wear may occur, which improves the processing accuracy and service life of the mold.

[0038] When slider 3 slides downward, the liquid outlet pipe 4 slides out of slider 3. At this time, the telescopic block 7 is pushed by the telescopic spring 6 and automatically pops out to automatically close the sliding opening inside slider 3, preventing the lubricant from leaking out from the sliding opening as slider 3 slides on support column 2, thus avoiding waste. When it is necessary to install or replace the lubricator 13, the fixing rods 14 on both sides of the lubricator 13 and the support plate 15 need to be aligned. At the same time, the quick-fixing assembly is slid into the opening of the fixing rods 14 and the support plate 15. During the sliding process, the four rotating rods 24 will slide forward due to the compression of the opening or by manually pushing the telescopic column 21, so that the four rotating rods 24 rotate and fit into the inside of the groove 8.

[0039] After sliding in, the rotating rod 24 is automatically expanded outwards by the force of the telescopic spring 25. Then, rotating the rotating ring 19 causes it to move forward along the threaded groove on the outside of the threaded column 18. The fixing is complete when the rotating rod 24 and the rotating ring 19 are tightly fitted against the fixing rod 14 and the support plate 15. For disassembly, rotate the rotating ring 19 backwards, then manually push the telescopic column 21 to make the rotating rod 24 fit into the groove 8. Then, pull the handle 20 backwards to slide it out, and finally lift the lubricating machine 13 upwards, completing the disassembly of the lubricating machine 13. The quick installation and disassembly of the lubricating machine 13 allows for rapid maintenance of the automatic lubrication system of the mold, avoiding delays in the use of the mold device.

[0040] 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.
