A four-wheel alignment mold guide pillar

Abstract

This utility model discloses a four-wheel positioning mold guide post, including an upper mold base. Mold guide sleeves are installed at the four corners of the lower end of the upper mold base. A protective ring is fitted on the outer wall of the mold guide sleeve at the lower position. The mold guide sleeve is inserted into the lower guide post at the lower end position through the mounting groove at the inner position. The lower guide post is filled with an appropriate amount of lubricating oil through the oil injection hole at the top position of the lower guide post. The lubricating oil enters the inner position of the oil storage tank, squeezing out the lubricating oil inside the sponge. At the same time, the stainless steel mesh plate moves to remove the movable cover plate from the top opening of the flow pipe, so that the lubricating oil passes through the mesh of the stainless steel mesh plate and enters the flow pipe, and is finally discharged to the external position through the oil outlet. The lubrication is increased when the mold guide sleeve and the lower guide post are inserted and installed, so that the mold guide sleeve and the lower guide post are smoothly connected.

Description

Technical Field

[0001] This utility model belongs to the technical field of four-wheel positioning mold guide pillars, specifically relating to a four-wheel positioning mold guide pillar. Background Technology

[0002] Four-wheel alignment mold guide pillars are core guiding components used in four-wheel alignment molds. They are usually made of high-strength, wear-resistant metal materials and are installed at corresponding positions on the upper and lower molds. Their core function is to guide the mold to accurately align during opening and closing movements, preventing component offset or jamming, and ensuring that the mold maintains a stable movement trajectory during processing or positioning. This indirectly ensures the accuracy and reliability of four-wheel alignment and is a key component for maintaining normal mold operation and improving positioning accuracy.

[0003] When using four-wheel positioning mold guide pillars, the lack of lubrication between the guide pillars and guide sleeves will increase frictional resistance, which will affect the smoothness of guidance. Therefore, the market needs a new device to solve the current problems. Utility Model Content

[0004] The purpose of this utility model is to provide a four-wheel positioning mold guide post to solve the problem mentioned in the background art. When using the four-wheel positioning mold guide post, the lack of lubrication between the guide post and the guide sleeve will increase the frictional resistance, which will affect the smoothness of the guide. Therefore, the market needs a new device to solve the current problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a four-wheel positioning mold guide post, including an upper mold base, mold guide sleeves installed at the four corners of the lower end of the upper mold base, a protective ring sleeved on the outer wall of the mold guide sleeve at the lower position, the mold guide sleeve being inserted into the lower guide post at the lower end position of the mold guide post through an internal mounting groove, movable rollers sleeved on the upper two sides of the internal groove of the lower guide post, and lubricating oil being added to the oil storage tank located inside the lower guide post through an oil injection hole at the top position.

[0006] Preferably, the upper part of the lower guide post has the same structure as the mounting groove, so that when the mold guide sleeve is connected to the lower guide post, the upper part of the lower guide post is inserted into the inner position of the mounting groove, so that the mold guide sleeve and the lower guide post form a longer column structure.

[0007] Preferably, the protective ring is fitted onto the outer wall of the mounting groove to increase the firmness of the mold guide sleeve and the lower guide post, and a lower mold base is fixed at the lower end of the lower guide post.

[0008] Preferably, a rotating shaft is fixed at both ends of the movable roller, and the rotating shaft is inserted into a groove on the inner wall of the groove.

[0009] Preferably, the mold guide sleeve and the lower guide post are installed to compress the movable roller, causing the movable roller to enter the groove, while the rotating shaft moves along the slide.

[0010] Preferably, stainless steel mesh plates are fitted on both sides of the inner side of the oil storage tank. The two stainless steel mesh plates are elastically connected by stainless steel springs fixed at the inner end face. The movable roller is in contact with the stainless steel mesh plates. Flow channels are provided on both sides of the inner side of the lower guide column. A movable cover plate fixed at the lower end of the stainless steel mesh plate covers the inlet at the top of the flow channel.

[0011] Preferably, the movable roller is squeezed and pushes the stainless steel mesh plate to move synchronously, and at the same time, the movement of the stainless steel mesh plate squeezes the sponge inside the oil storage tank.

[0012] Preferably, multiple oil outlet holes are distributed at the front and rear ends of the lower guide post on the outer wall of the lower guide post, and the oil outlet holes lead to the flow channel.

[0013] Compared with the prior art, this utility model provides a four-wheel positioning mold guide post, which has the following beneficial effects: 1. This device adds an appropriate amount of lubricating oil through the oil injection hole at the top of the lower guide post. The lubricating oil enters the oil storage tank and is simultaneously immersed in the sponge. During the insertion installation of the mold guide sleeve and the lower mold base, when the mold guide sleeve contacts the roller, the roller enters the inner position of the groove. The movement of the roller pushes the stainless steel mesh plate to move, and the movement of the stainless steel mesh plate squeezes the sponge, squeezing out the lubricating oil inside the sponge. At the same time, the movement of the stainless steel mesh plate moves the movable cover plate out from the top opening of the flow pipe, allowing the lubricating oil to pass through the mesh of the stainless steel mesh plate into the flow pipe, and finally be discharged to the external position through the oil outlet. This increases the lubrication during the insertion installation of the mold guide sleeve and the lower guide post, ensuring a smooth connection between the mold guide sleeve and the lower guide post.

[0014] 2. The stainless steel spring, through its elastic force, pushes the stainless steel mesh plates on both sides to adhere to the inner wall of the oil storage tank. The stainless steel mesh plates push the movable roller outward, so that part of its area is located on the outer wall of the lower guide post. In this way, the mold guide sleeve can squeeze the movable roller during its downward movement, allowing it to enter the interior of the lower guide post and push the stainless steel mesh plate to move. The movable roller can also move via a rotating shaft, which moves along the slide groove. This method avoids affecting the installation of the guide sleeve and the guide post.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The utility model provides, for example Figure 1-4 The four-wheel positioning mold guide pillar shown includes an upper mold base 1. Mold guide sleeves 2 are installed at the four corners of the lower end of the upper mold base 1. A protective ring 3 is fitted on the outer wall of the mold guide sleeve 2 at the lower position. The mold guide sleeve 2 is inserted into the lower guide pillar 6 at the lower end position through the mounting groove 4 at the internal position. Movable rollers 8 are fitted on the upper two sides of the internal groove of the lower guide pillar 6. Lubricating oil can be added to the oil storage tank 14 located inside the lower guide pillar 6 through the oil injection hole 7 at the top position.

[0023] During the mold assembly stage, the mold guide sleeve 2 is usually fixed at the four corners of the upper mold base 1 at equal intervals, forming a mating base with the lower guide post 6 at the corresponding position of the lower mold base 5. When the mold enters the mold closing process, the upper mold base 1 drives the mold guide sleeve 2 to move downward to the guide post. During the process, the protective ring 3 on the guide sleeve prevents the mold from shifting or misaligning. When the casting enters the mold opening process, the mold guide sleeve 2 moves upward synchronously with the upper mold base 1 to complete the mold opening work.

[0024] like Figure 1 and Figure 2 As shown, the upper part of the lower guide post 6 has the same structure as the mounting groove 4, so that when the mold guide sleeve 2 is connected to the lower guide post 6, the upper part of the lower guide post 6 is inserted into the inner position of the mounting groove 4, so that the mold guide sleeve 2 and the lower guide post 6 form a longer column structure. The protective ring 3 is sleeved on the outer wall of the mounting groove 4 to increase the firmness of the installation of the mold guide sleeve 2 and the lower guide post 6. The lower mold base 5 is fixed at the lower end of the lower guide post 6, and the rotating shaft 10 is fixed at both ends of the movable roller 8. At the same time, the rotating shaft 10 is inserted into the sliding groove 11 at the inner wall of the groove.

[0025] Based on the existing mold guide sleeve 2, optimization and improvement are made by adding a four-wheel positioning protective ring 3 to the existing mold guide sleeve. This reduces wear and deformation during casting production, reduces the time for surface maintenance of castings during machine production, improves production efficiency, extends the life of mold guide sleeve 2 after adding protective ring 3, reduces the production manpower for replacing guide sleeves, and reduces the cost of purchasing new products.

[0026] like Figure 3 and Figure 4As shown, the mold guide sleeve 2 and the lower guide post 6 are installed to compress the movable roller 8, causing the movable roller 8 to enter the groove. At the same time, the rotating shaft 10 moves along the slide 11. Stainless steel mesh plates 15 are sleeved on both sides of the inside of the oil storage tank 14. The two stainless steel mesh plates 15 are elastically connected by stainless steel springs 12 fixed at the inner end face. The movable roller 8 is in contact with the stainless steel mesh plates 15. Flow channels 17 are provided on both sides of the inside of the lower guide post 6. The movable cover plate 16 fixed at the lower end of the stainless steel mesh plate 15 covers the entrance at the top of the flow channel 17. The movable roller 8 is compressed and pushes the stainless steel mesh plate 15 to move synchronously. At the same time, the movement of the stainless steel mesh plate 15 compresses the sponge 13 inside the oil storage tank 14. Multiple oil outlet holes 9 are distributed at the front and rear ends of the lower guide post 6 on the outer wall of the lower guide post 6. The oil outlet holes 9 lead to the flow channel 17.

[0027] The stainless steel spring 12, through its elastic force, pushes the stainless steel mesh plates 15 at both sides to adhere to the inner wall of the oil storage tank 14. The stainless steel mesh plates 15 push the movable roller 8 outward, so that part of its area is located on the outer wall of the lower guide post 6. In this way, the mold guide sleeve 2 can squeeze the movable roller 8 during the downward movement, allowing it to enter the inner position of the lower guide post 6, pushing the stainless steel mesh plate 15 to move. The movable roller 8 can also move through the rotating shaft 10, while the rotating shaft 10 moves along the slide groove 11.

[0028] 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.
