Description

Technical Field

[0001] This utility model belongs to the technical field of guide post structures, specifically relating to a self-lubricating guide post structure. Background Technology

[0002] As a core guiding component of the mold, the guide rod's primary function is to ensure precise guidance and positioning when the moving mold and fixed mold are closed, preventing molding defects caused by misalignment. Currently, to reduce wear and improve the stability of the guide rod structure during operation, lubrication mechanisms or manual application of lubricating oil are commonly used to lubricate the guide rod structure.

[0003] However, setting up a lubrication mechanism will increase the weight of the mold, causing the guide pillar structure to bear a greater weight when working. On the other hand, the manual lubrication method is not intelligent enough, resulting in the guide pillar structure not being lubricated in time. Both of these lubrication methods will affect the guide pillar structure in the working state, and will also cause the guide pillar structure to deform due to a decrease in its resistance to deformation, thereby affecting the normal use of the mold.

The elastic element is located between the base plate and the inner sleeve, and the elastic element is connected to both the base plate and the inner sleeve.

[0007] As an improvement to the self-lubricating guide post structure of this utility model, it also includes a guide sleeve, the inner surface of which is sleeved on the outer surface of the inner sleeve, and a lubricating layer is provided between the outer surface of the inner sleeve and the inner surface of the guide sleeve; the first end of the elastic member is connected to the base plate, and the second end of the elastic member is connected to the bottom end of the inner sleeve.

[0008] As an improvement to the self-lubricating guide post structure of this utility model, a buffer platform is also provided on the base plate. The ends of the guide rod and the elastic element near the base plate are both connected to the top of the buffer platform. The buffer platform has a receiving cavity inside, and the receiving cavity is filled with multiple buffer particles.

[0009] As an improvement to the self-lubricating guide post structure of this utility model, the buffer particles are made of carbon fiber composite material.

[0010] As an improvement of the self-lubricating guide post structure of this utility model, the self-lubricating guide post structure further includes: multiple oil-separating components, the top end of the guide rod is provided with a movable cavity, the number of movable cavities, the number of oil-separating components and the number of oil outlet holes are all equal, each movable cavity and each oil outlet hole are connected in a one-to-one correspondence, and the oil-separating component extends from the movable cavity to the oil outlet hole.

[0011] As an improvement to the self-lubricating guide post structure of this utility model, each of the oil-separating components includes: a slide rod and a magnetic oil baffle plate. The slide rod is slidably disposed in the movable cavity, and the magnetic oil baffle plate is located in the movable cavity and connected to the end of the slide rod near the oil outlet.

[0012] As an improvement to the self-lubricating guide post structure of this utility model, the self-lubricating guide post structure further includes: a magnetic component, and mounting grooves are respectively spaced apart on both sides of the movable cavity. Each mounting groove is provided with a magnetic component, which can be bonded or welded to the mounting groove. The magnetic component exactly fills the space of the mounting groove and is used to magnetically attract the magnetic oil baffle.

[0013] As an improvement to the self-lubricating guide post structure of this utility model, the magnetic oil baffle is made of ferritic stainless steel.

Detailed Implementation

[0026] Example 1

[0027] like Figures 2 to 5 As shown, a self-lubricating guide post structure includes: a base plate 10, an oil-absorbing cotton 30, an inner sleeve 40, a guide sleeve 50, and an elastic element 60. A guide rod 20 is provided on the base plate 10, and an oil storage cavity 21 is opened inside the guide rod 20. At least two oil outlet holes 22 are opened at intervals on the side wall of the oil storage cavity 21, and the oil outlet holes 22 penetrate the guide rod 20. The oil-absorbing cotton 30 is disposed in the oil outlet holes 22 and at least partially protrudes from the outer surface of the guide rod 20. The inner surface of the inner sleeve 40 is movably sleeved on the guide rod 20, and the inner surface of the inner sleeve 40 movably squeezes the oil-absorbing cotton 30. A lubricating layer 41 is provided on the outer surface of the inner sleeve 40. The inner surface of the guide sleeve 50 is sleeved on the outer surface of the inner sleeve 40. The first end of the elastic element 60 is connected to the base plate 10, and the second end of the elastic element 60 is connected to the bottom end of the inner sleeve 40. During use, the oil-absorbing cotton 30 absorbs lubricating oil from the oil storage cavity 21 through the oil outlet 22. When the mold opens and closes, the inner sleeve 40 presses down on the elastic element 60. The elastic element 60 buffers the pressure of the inner sleeve 40 pressing down, preventing the inner sleeve 40 from directly impacting the base plate 10 and causing deformation of the guide post structure. The inner surface of the inner sleeve 40 interacts with the guide rod 20 to squeeze the oil-absorbing cotton 30 protruding from the guide rod 20, which can squeeze the lubricating oil in the oil-absorbing cotton 30 to the space between the inner surface of the inner sleeve 40 and the guide rod 20, thereby achieving lubrication between the inner sleeve 40 and the guide rod 20. At the same time, the guide rod 20... The outer surface of sleeve 50 also interacts with the outer surface of inner sleeve 40 to form a lubricating film, so as to achieve mutual lubrication between inner sleeve 40 and guide sleeve 50. When the lubricating oil in oil-absorbing cotton 30 is squeezed out, oil-absorbing cotton 30 can also automatically absorb the lubricating oil to achieve automatic replenishment of lubricating oil. Through the above settings, the inner sleeve 40 and guide sleeve 50 can be continuously and stably lubricated during the up and down movement, effectively reducing the overall wear of the guide post structure during operation, reducing the risk of deformation of the guide post structure, thereby enhancing the operational reliability and deformation resistance of the guide post structure.

[0028] Furthermore, when using this guide post structure to achieve the required guidance, the two guide post structures installed at different heights can be connected by a flange, thereby effectively achieving the guiding effect of the guide post structure. The flange can fix the top part of the guide rod 20 extending out of the inner sleeve 40.

[0029] Preferably, the base plate 10 is also provided with a buffer platform 11, and the guide rod 20 is located at the top center of the buffer platform 11. The guide rod 20 and the end of the elastic member 60 near the base plate 10 are both connected to the top of the buffer platform 11, so that the first end of the elastic member 60 is connected to the top of the buffer platform 11.

[0030] In some embodiments, the buffer platform 11 has an internal cavity 110 filled with multiple buffer particles 111. When the mold opens and closes, the guide sleeve 50 drives the inner sleeve 40 to press down on the elastic member 60. After the elastic member 60 absorbs part of the pressure, the remaining pressure is transmitted to the buffer particles 111 in the cavity 110. The buffer particles 111 are made of a high-rigidity material, which allows the pressure to be more evenly distributed to all parts of the buffer platform 11 through the buffer particles 111, reducing local pressure concentration and thus reducing the risk of deformation of the guide column structure.

[0031] In some embodiments, the self-lubricating guide post structure further includes: a plurality of oil-separating components 70, with a movable cavity 23 opened at the top of the guide rod 20. The number of movable cavities 23, oil-separating components 70, and oil outlet holes 22 are equal. The movable cavity 23 is connected to the oil outlet hole 22. The oil-separating component 70 extends from the movable cavity 23 to the oil outlet hole 22. The oil-separating component 70 includes: a slide rod 71 and a magnetic oil baffle 72. The slide rod 71 is slidably disposed in the movable cavity 23. The magnetic oil baffle 72 is located in the movable cavity 23 and connected to one end of the oil outlet hole 22 near the slide rod 71. The slide rod 71 can drive the magnetic oil baffle 72 to rise and fall, thereby changing the position of the magnetic oil baffle 72 in the oil outlet hole 22. This forms different blocking areas and changes the size of the oil outlet hole 22, thereby flexibly controlling the amount of oil in the oil outlet hole 22 according to the opening and closing rate of the mold, controlling the amount of lubricating oil absorbed by the oil-absorbing cotton 30, and realizing flexible lubrication of the guide post structure. When in use, the size of the oil outlet 22 can be adjusted before connecting the upper and lower flanges of the two guide pillar structures.

[0032] Preferably, the self-lubricating guide post structure further includes: a magnetic component 80. Mounting grooves 24 are spaced apart on both sides of the movable cavity 23. A magnetic component 80 is placed in each mounting groove 24, filling the space exactly. The magnetic component 80 is used to magnetically attract the magnetic oil baffle 72. The magnetic component 80 has weak magnetism. When the slide rod 71 moves the magnetic oil baffle 72, the lift force of the magnetic oil baffle 72 is greater than the magnetic force of the two opposing magnetic components 80. At this time, the magnetic component 80 cannot attract the magnetic oil baffle 72. When the slide rod 71 stops moving, the magnetic force of the two opposing magnetic components 80 can attract both sides of the magnetic oil baffle 72, thereby fixing the position of the magnetic oil baffle 72 after its movement, allowing the magnetic oil baffle 72 to stably change the size of the oil outlet 22.

[0033] Preferably, the self-lubricating guide post structure further includes: an oil cap 90; a threaded hole 12 is provided at the top of the guide rod 20, the threaded hole 12 communicates with the oil reservoir 21; a threaded rod 91 is provided on the oil cap 90, the threaded rod 91 is screwed to the side wall of the threaded hole 12; the oil cap 90 movably closes the oil reservoir 21. The oil reservoir 21 can be flexibly opened and closed by screwing the threaded rod 91 in or out, which facilitates the addition of lubricating oil to the oil reservoir 21 while preventing external dust from entering the oil reservoir 21 and contaminating the lubricating oil.

[0034] Example 2

[0035] Unlike Example 1, see [link to example]. Figure 2 The buffer particles 111 are made of carbon fiber composite material. Carbon fiber composite material has high rigidity, and high rigidity material has high elastic modulus. After being filled into the receiving cavity 110, it can significantly improve the overall rigidity of the guide rod 20. The material with high elastic modulus has small deformation when subjected to force. After being filled with high rigidity material, the pressure applied to the buffer platform 11 by the guide sleeve 50 can be more evenly distributed to the entire cross section of the buffer platform 11 through each carbon fiber composite material, thereby improving the deformation resistance of the guide rod 20.

[0036] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0037] Example 3

[0038] Unlike Example 1, see [link to example]. Figure 2 and Figure 4 The magnetic oil baffle 72 is made of ferritic stainless steel, and the magnetic component 80 is a magnet. Ferritic stainless steel is magnetic and has excellent corrosion resistance. It can be attracted by a magnet while also preventing corrosion from the lubricating oil in the oil outlet channel.

[0039] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0040] Example 4

[0041] Unlike Example 1, see [link to Example 1] Figure 2 and Figure 3 The lubrication layer 41 is a graphite copper lubrication layer 41. When the inner surface of the guide sleeve 50 interacts with the outer surface of the inner sleeve 40, the graphite copper layer can release the graphite in the copper base. Graphite has self-lubricating properties, so it can form a lubricating film on the inner surface of the guide sleeve 50 and the outer surface of the inner sleeve 40 to achieve lubrication between the inner surface of the guide sleeve 50 and the outer surface of the inner sleeve 40.

[0042] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0043] Example 5

[0044] Unlike Example 1, see [link to Example 1] Figure 1 and Figure 2 The elastic element 60 is a spring, and the elastic element 60 is sleeved on the guide rod 20.

[0045] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0046] Example 6

[0047] Unlike embodiments 1 to 5, the inner surface of the inner sleeve 40 surrounds the end of the multiple slide rods 71 ​​away from the oil outlet 22. This allows the top periphery of the inner surface of the inner sleeve 40 to be higher than or flush with the top of the slide rods 71 ​​when it is not under pressure. When the upper and lower flanges of the two guide pillar structures are connected, the inner sleeve 40 is compressed and squeezes the oil-absorbing cotton 30, thereby efficiently realizing the self-lubrication of the guide pillar structure.

[0048] The other structures in this embodiment are the same as those in embodiments 1 to 5, and will not be described again here.
