Description

Technical Field

[0001] This utility model relates to the field of mold accessories, specifically to a self-lubricating mold guide post. Background Technology

[0002] Mold guide pillars, also known as guide posts, are important components in molds. Their main function is to guide the upper and lower molds to align correctly, ensuring the accuracy of the mold's movement direction. Guide pillars are typically divided into fixed sections, guiding sections, and directing sections, each with clearly defined length requirements to ensure precise guiding.

[0003] Guide pillars require regular lubrication during use. Traditional lubrication involves manually applying lubricating oil. However, this manual application can lead to oil dripping and waste, and it also requires workers to spend a significant amount of time applying the lubricating oil, increasing their workload. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating mold guide post to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-lubricating mold guide post, comprising a guide post, a guide sleeve and a spring sleeved on the guide post, and a base fixedly disposed below the guide post. The upper and lower ends of the spring are respectively fixedly connected to the guide sleeve and the base. The feature is that a sponge sleeve sleeved on the guide post is fixedly disposed below the guide sleeve. The sponge sleeve is located between the guide post and the spring and is in contact with the guide post. An oil inlet groove is opened on the top wall of the base, located directly below the sponge sleeve. An oil inlet hole communicating with the oil inlet groove is opened on the outer wall of the base. A plug is detachably disposed inside the oil inlet hole.

[0006] Preferably, the outer wall of the guide post is provided with a plurality of oil passage grooves, the guide post is provided with a plurality of oil passage holes A that communicate with the oil passage grooves through the left and right sides, the guide post is provided with an oil passage hole B that connects to the oil passage holes A through the inside, and the guide post is provided with an oil passage hole C that connects the oil inlet groove and the oil passage hole B through the left and right sides.

[0007] Preferably, an elastic pad is fixedly installed inside the oil inlet groove, and an oil scraping groove is formed through the upper and lower parts of the elastic pad.

[0008] Preferably, an oil baffle is fixedly installed above the base, and the oil baffle is located between the sponge sleeve and the spring.

[0009] Preferably, the inner side of the oil inlet hole and the outer side of the plug are both provided with threads, the plug is screwed into the oil inlet hole and fixedly connected to the base by the threads, and a rotating column located outside the oil inlet hole is fixedly provided on the plug.

[0012] The beneficial effects of this utility model are as follows: When using this utility model, lubricating oil is added into the oil inlet groove through the oil inlet hole, and then the plug is screwed into the oil inlet hole to prevent lubricating oil leakage. The guide sleeve slides downwards, causing the sponge sleeve to slide downwards as well. The oil inlet groove is located directly below the sponge sleeve, which inserts into the oil inlet groove and is immersed in lubricating oil. The guide sleeve slides upwards, causing the sponge sleeve to slide upwards, connecting with the guide post. The sponge sleeve applies lubricating oil to the surface of the guide post, providing lubrication. The sponge sleeve continuously lubricates the guide post as the guide sleeve reciprocates, eliminating the need for manual application and achieving automatic lubrication. When there is excessive lubricating oil on the guide post surface, the lubricating oil flows back into the oil inlet groove through the oil channel, oil channel A, oil channel B, and oil channel C, allowing for oil recycling and preventing waste. In summary, this utility model has the beneficial effects of automatic lubrication and preventing waste, solving the problem that manual application of lubricating oil easily leads to dripping and waste, and that workers need to spend a lot of time applying the lubricating oil, increasing their workload.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1-4As shown, this utility model discloses a self-lubricating mold guide post, including a guide post 1, a guide sleeve 2 and a spring 3 sleeved on the guide post 1, and a base 4 fixedly disposed below the guide post 1. The upper and lower ends of the spring 3 are fixedly connected to the guide sleeve 2 and the base 4 respectively. A sponge sleeve 5 sleeved on the guide post 1 is fixedly disposed below the guide sleeve 2. The sponge sleeve 5 is located between the guide post 1 and the spring 3 and is in contact with the guide post 1. An oil inlet groove 6 is opened on the top wall of the base 4, located directly below the sponge sleeve 5. An oil inlet hole 7 communicating with the oil inlet groove 6 is opened on the outer side wall of the base 4. A plug 8 is detachably disposed inside the oil inlet hole 7. In use, lubricating oil is added to the oil inlet groove 6 through the oil inlet hole 7, and then the plug 8 is screwed into the oil inlet hole 7 to block the oil inlet hole 7 and prevent lubricating oil leakage. The guide sleeve 2 slides downward, causing the sponge sleeve 5 to slide downward. The oil inlet groove 6 is located directly below the sponge sleeve 5, and the sponge sleeve 5 will be inserted into the oil inlet groove 6 and immersed in lubricating oil. The guide sleeve 2 slides upward, causing the sponge sleeve 5 to slide upward. The sponge sleeve 5 contacts and connects with the guide post 1, and the sponge sleeve 5 will apply lubricating oil to the surface of the guide post 1, thus playing a lubricating role. The sponge sleeve 5 moves back and forth with the guide sleeve 2, thereby continuously lubricating the guide post 1. Lubrication is achieved automatically without manual application; when there is too much lubricating oil on the surface of the guide post 1, the lubricating oil will flow back into the oil groove 6 through the oil groove 9, oil hole A10, oil hole B11 and oil hole C12, which allows the lubricating oil to be recycled and prevents waste. In summary, this utility model has the beneficial effects of automatic lubrication and prevention of waste, and solves the problem that manual application of lubricating oil is prone to dripping and causing waste, and that workers need to spend a lot of time applying it, which increases their workload.

[0020] Preferably, the outer wall of the guide post 1 is provided with several oil grooves 9, and the guide post 1 is provided with several oil holes A10 that communicate with the oil grooves 9 through the left and right sides. The guide post 1 is provided with an oil hole B11 that connects to the oil holes A10 through the left and right sides, and the guide post 1 is provided with an oil hole C12 that connects the oil inlet groove 6 and the oil holes B11 through the left and right sides. Since the guide post 1 is provided with an oil hole C12 that connects the oil inlet groove 6 and the oil holes B11 through the left and right sides, when there is too much lubricating oil on the surface of the guide post 1, the lubricating oil will flow back into the oil inlet groove 6 through the oil grooves 9, oil holes A10, oil holes B11 and oil holes C12, which facilitates the recycling of lubricating oil.

[0021] Preferably, an elastic pad 13 is fixedly installed inside the oil inlet groove 6, and an oil scraping groove 14 is formed through the upper and lower parts of the elastic pad 13. Because an elastic pad 13 is fixedly installed inside the oil inlet groove 6, and an oil scraping groove 14 is formed through the upper and lower parts of the elastic pad 13, when the sponge sleeve 5 is inserted into and pulled out of the oil inlet groove 6, it will pass through the oil scraping groove 14 and be squeezed by the elastic pad 13, squeezing out excess lubricating oil, which plays a role in preventing the sponge sleeve 5 from being soaked in too much lubricating oil.

[0022] Preferably, an oil-blocking sleeve 15 is fixedly installed above the base 4, and the oil-blocking sleeve 15 is located between the sponge sleeve 5 and the spring 3. Since the oil-blocking sleeve 15 is located between the sponge sleeve 5 and the spring 3, when the sponge sleeve 5 is squeezed by the elastic pad 13, some lubricating oil will splash. The oil-blocking sleeve 15 will block the splashed lubricating oil and allow it to flow back into the oil groove 6, thus preventing unnecessary loss of lubricating oil.

[0023] Preferably, both the inner side of the oil inlet hole 7 and the outer side of the plug 8 are threaded. The plug 8 is screwed into the oil inlet hole 7 and threadedly fixedly connected to the base 4. A rotating post 16 located on the outer side of the oil inlet hole 7 is fixedly installed on the plug 8. Since the plug 8 is screwed into the oil inlet hole 7 and threadedly fixedly connected to the base 4, and the rotating post 16 located on the outer side of the oil inlet hole 7 is fixedly installed on the plug 8, it facilitates the installation and removal of the plug 8.

[0024] Preferably, a filter screen 17 is fixedly installed inside the oil inlet hole 7. Because the filter screen 17 is fixedly installed inside the oil inlet hole 7, it filters impurities, thereby protecting the surface of the guide post 1.

[0025] Preferably, the rotating column 16 is provided with anti-slip texture 18. The anti-slip texture 18 on the rotating column 16 serves to prevent slippage.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
