AI Technical Summary
Existing mold guide pillars need to be replaced entirely after wear, resulting in waste, especially when used frequently, the replacement is even more frequent.
An assembled mold guide post was designed, including a guide sleeve assembly and a lubrication assembly. The guide post and the mounting sleeve are detachably fixed by screws and studs. The lubricating oil reduces friction and extends service life. When wear occurs, only the mounting sleeve is replaced instead of the entire guide post.
This avoids the waste of scrapping the entire mold after the guide post surface wears down, extends the service life of the mold, and reduces the replacement frequency and cost.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold accessories, specifically to an assembled mold guide pillar. 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] Mold guide pillars are critical components in molds, playing a vital role in guiding and supporting them. However, with prolonged use, guide pillars suffer performance degradation due to wear and fatigue, leading to decreased mold precision. Therefore, regular guide pillar replacement is necessary. Currently, when replacing guide pillars in molds, the entire guide pillar is typically replaced. However, this often results in the guide pillar being worn on the surface while remaining intact internally, making direct scrapping wasteful. This is especially problematic for frequently used molds, where guide pillar replacements are even more frequent, leading to even greater waste. Utility Model Content
[0004] The purpose of this invention is to provide an assembled 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: an assembled mold guide post, comprising a guide post and a base fixedly disposed below the guide post, characterized in that: the guide post is provided with a guide sleeve assembly, the guide sleeve assembly comprising an mounting sleeve sleeved on the guide post, a bottom ring fixedly disposed below the mounting sleeve, a pressure ring sleeved on the mounting sleeve, a pressure cap, a plurality of screws, and a lubrication assembly; an annular groove is formed on the top wall of the base, the bottom ring is inserted into the annular groove and abuts against the base; a plurality of screw holes A and through holes A are respectively formed on the base and the pressure ring; after the screws are inserted into the through holes A and screwed into the screw holes A, the pressure ring is fixedly connected to the base and the bottom ring; a stud is fixedly disposed below the pressure cap; a screw hole B is formed on the top wall of the guide post, after the stud is screwed into the screw hole B, the pressure cap is fixedly connected to the guide post and the mounting sleeve.
[0006] Preferably, the guide sleeve assembly further includes a ball sleeve and a spring A sleeved on the mounting sleeve, and a sliding sleeve sleeved on the ball sleeve, wherein the upper and lower ends of the spring A are fixedly connected to the ball sleeve and the pressure ring, respectively.
[0007] Preferably, the lubrication assembly includes a ring fixedly disposed above the sliding sleeve, an annular oil pipe located above the pressure cap, and a plurality of droppers fixedly disposed below the annular oil pipe. The pressure cap has a plurality of through holes B, the droppers are located in the through holes B, the ring is located directly above the annular oil pipe, and the droppers are located directly above the ball bearing sleeve.
[0008] Preferably, the guide sleeve assembly further includes a spring B and a positioning ball fixedly disposed above the spring B. A telescopic groove is formed on the bottom wall of the annular groove, the spring B is located inside the telescopic groove, the positioning ball is located outside the telescopic groove, and a ball groove matching the positioning ball is formed on the bottom wall of the bottom ring. The positioning ball is located inside the ball groove and abuts against the bottom ring.
[0009] Preferably, the guide sleeve assembly further includes an insert, and slots A and B are respectively provided on the outer side wall of the guide post and the inner side wall of the mounting sleeve. When the positioning ball is located in the ball groove, slots A and B are aligned. After the insert is inserted into slots A and B, it abuts against the guide post and the mounting sleeve.
[0010] Preferably, a hexagonal head is fixedly provided on the top of the pressure cap.
[0011] Preferably, the material of the ring is natural rubber.
[0012] The beneficial effects of this utility model are as follows: When using this utility model, spring B is placed in the telescopic groove, so that the positioning ball is outside the telescopic groove. The mounting sleeve is placed on the guide post, and the bottom ring is inserted into the ring groove and abuts against the base. The bottom ring will press the positioning ball into the telescopic groove. Slowly rotate the mounting sleeve to align the positioning ball with the ball groove. Spring B will spring the positioning ball into the ball groove and abut against the bottom ring. At this time, slot A and slot B are aligned. After inserting the insert into slot A and slot B, it abuts against the guide post and mounting sleeve, limiting the mounting sleeve and preventing it from rotating during subsequent use. This avoids wear caused by friction between the mounting sleeve and the guide post. The screw is inserted into the through hole A and screwed into the screw hole A to fix the pressure ring to the base and the bottom ring, thus fixing the guide post to the mounting sleeve. Spring B and the ball sleeve are placed on the mounting sleeve, and the stud is screwed into the screw hole B to fix the pressure cap to the guide post and the mounting sleeve, further fixing the guide post to the mounting sleeve. The annular oil pipe is placed above the pressure cap and the dropper is inserted into the through hole B. Inside, a sliding sleeve is fitted onto a ball sleeve, with the ring positioned directly above the annular oil pipe and the dropper positioned directly above the ball sleeve. When the mold is working, the sliding sleeve slides up and down, and the ring squeezes the annular oil pipe (containing lubricating oil), causing the lubricating oil to drip from the dropper into the ball sleeve. The lubricating oil lubricates the ball sleeve, thereby reducing friction between the ball sleeve and the mounting sleeve during mold operation and extending the service life of the mounting sleeve. When the mold needs to be replaced after long-term, high-frequency operation, the sliding sleeve and ball sleeve are removed one by one, and the screws and studs are unscrewed from screw holes A and B respectively to remove the mounting sleeve. Then, a new mounting sleeve is installed with the guide post (process as above), eliminating the need to replace the entire guide post and avoiding waste. In summary, this utility model has the beneficial effect of avoiding waste, solving the problem of directly scrapping a guide post that is still intact after surface wear, which is wasteful, especially for high-frequency molds where guide post replacement is more frequent, leading to even greater waste.

[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 an assembled mold guide post, including a guide post 1 and a base 2 fixedly disposed below the guide post 1. The guide post 1 is provided with a guide sleeve assembly, which includes an mounting sleeve 3 sleeved on the guide post 1, a bottom ring 4 fixedly disposed below the mounting sleeve 3, a pressure ring 5 sleeved on the mounting sleeve 3, a pressure cap 6, several screws 7, and a lubrication assembly. The top wall of the base 2 is provided with an annular groove 8, and the bottom ring 4 is inserted into the annular groove 8 and abuts against the base 2. Several screw holes A9 and through holes A10 are respectively provided on the base 2 and the pressure ring 5. After the screws 7 are inserted into the through holes A10 and screwed into the screw holes A9, the pressure ring 5 is fixedly connected to the base 2 and the bottom ring 4. A stud 11 is fixedly disposed below the pressure cap 6. A screw hole B12 is provided on the top wall of the guide post 1. After the stud 11 is screwed into the screw hole B12, the pressure cap 6 is fixedly connected to the guide post 1 and the mounting sleeve 3.In use, spring B20 is placed into the telescopic groove 22, so that the positioning ball 21 is outside the telescopic groove 22. The mounting sleeve 3 is then placed on the guide post 1, and the bottom ring 4 is inserted into the ring groove 8 and contacts the base 2. The bottom ring 4 will press the positioning ball 21 into the telescopic groove 22. The mounting sleeve 3 is slowly rotated to align the positioning ball 21 with the ball groove 23. Spring B20 will then spring the positioning ball 21 into the ball groove 23 and contact the bottom ring 4. At this point, slot A25 and slot B26 are aligned. The insert strip 24 is then inserted into slots A25 and B26, connecting with the guide post 1 and the mounting sleeve 3. The mounting sleeve 3 is positioned to prevent rotation during subsequent use and to avoid wear caused by friction between the mounting sleeve 3 and the guide post 1. Screw 7 is inserted into through hole A10 and screwed into screw hole A9 to fix the pressure ring 5 to the base 2 and bottom ring 4, thus fixing the guide post 1 to the mounting sleeve 3. Spring B20 and ball sleeve 13 are fitted onto the mounting sleeve 3, and stud 11 is screwed into screw hole B12 to fix the pressure cap 6 to the guide post 1 and mounting sleeve 3, further securing the guide post 1 to the mounting sleeve 3. The annular oil pipe 17 is placed above the pressure cap 6, and the dropper... Insert the sliding sleeve 15 into the through hole B19, and place it on the ball sleeve 13, so that the ring 16 is directly above the annular oil pipe 17 and the dropper 18 is directly above the ball sleeve 13. When the mold is working, the sliding sleeve 15 slides up and down, and the ring 16 will squeeze the annular oil pipe (containing lubricating oil), causing the lubricating oil to drip from the dropper 18 into the ball sleeve 13. The lubricating oil lubricates the ball sleeve 13, thereby reducing the friction between the ball sleeve 13 and the mounting sleeve 3 when the mold is working, and extending the service life of the mounting sleeve 3. When the mold is working at high frequency for a long time, it needs to be replaced. When replacing the mounting sleeve 3, remove the sliding sleeve 15 and the ball sleeve 13 one by one, then unscrew the screw 7 and the stud 11 out of the screw holes A9 and B12 respectively, and the mounting sleeve 3 can be removed. Then install the new mounting sleeve 3 with the guide post 1 (the process is as above). There is no need to replace the entire guide post 1, which avoids waste. In summary, this utility model has the beneficial effect of avoiding waste. It solves the problem that it is wasteful to scrap the guide post 1 directly after the surface is worn but the inside is intact. This is especially true for molds that are used frequently, where the replacement of the guide post 1 is more frequent, leading to even more waste.
[0020] Preferably, the guide sleeve assembly further includes a ball sleeve 13 and a spring A14 sleeved on the mounting sleeve 3, and a sliding sleeve 15 sleeved on the ball sleeve 13. The upper and lower ends of the spring A14 are fixedly connected to the ball sleeve 13 and the pressure ring 5, respectively. Since the upper and lower ends of the spring A14 are fixedly connected to the ball sleeve 13 and the pressure ring 5, respectively, it plays a role in automatic demolding and buffering and shock absorption.
[0021] Preferably, the lubrication assembly includes a ring 16 fixedly disposed above the sliding sleeve 15, an annular oil pipe 17 located above the pressure cap 6, and several droppers 18 fixedly disposed below the annular oil pipe 17. The pressure cap 6 has several through holes B19, with the droppers 18 located within the through holes B19. The ring 16 is located directly above the annular oil pipe 17, and the droppers 18 are directly above the ball sleeve 13. Because the droppers 18 are located within the through holes B19, the ring 16 is directly above the annular oil pipe 17, and the droppers 18 are directly above the ball sleeve 13, when the mold operates, the sliding sleeve 15 slides up and down. The ring 16 squeezes the annular 5-shaped oil pipe (containing lubricating oil and having an oil filling port), causing the lubricating oil to drip from the droppers 18 into the ball sleeve 13, thus lubricating the ball sleeve 13 and extending the service life of the mounting sleeve 3 and the ball sleeve 13.
[0022] Preferably, the guide sleeve assembly further includes a spring B20 and a positioning ball 21 fixedly disposed above the spring B20. A telescopic groove 22 is formed on the bottom wall of the annular groove 8. The spring B20 is located inside the telescopic groove 22, and the positioning ball 21 is located outside the telescopic groove 22. A ball groove 23 matching the positioning ball 21 is formed on the bottom wall of the bottom ring 4. The positioning ball 21 is located inside the ball groove 23 and abuts against the bottom ring 4. Because the spring B20 is located inside the telescopic groove 22 and the positioning ball 21 is located outside the telescopic groove 22, the positioning ball 21 is aligned with the ball groove 23. The spring B20 will spring the positioning ball 21 into the ball groove 23 and abut against the bottom ring 4, thus facilitating positioning and telescopic movement.
[0023] Preferably, the guide sleeve assembly further includes an insert 24. Slots A25 and B26 are respectively provided on the outer side wall of the guide post 1 and the inner side wall of the mounting sleeve 3. When the positioning ball 21 is located within the ball groove 23, slots A25 and B26 are aligned. After the insert 24 is inserted into slots A25 and B26, it abuts against the guide post 1 and the mounting sleeve 3. Since slots A25 and B26 are aligned when the positioning ball 21 is located within the ball groove 23, it positions slots A25 and B26, facilitating the insertion of the insert 24. The insert 24 limits the mounting sleeve 3, preventing it from rotating during subsequent use and avoiding wear caused by friction between the mounting sleeve 3 and the guide post 1.
[0024] Preferably, a hexagonal head 27 is fixedly provided on the top of the pressure cap 6. The hexagonal head 27 fixedly provided on the top of the pressure cap 6 facilitates the installation and removal of the pressure cap 6.
[0025] Preferably, the material of the ring 16 is natural rubber. Because the material of the ring 16 is natural rubber, the ring 16 will not continuously compress the annular oil pipe when it squeezes the ring 5. After compression, it will be lifted by the annular oil pipe 17, thus achieving the effect of discharging an appropriate amount of oil.
[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.
