Description
Technical Field
[0001] The utility model relates to the technical field of slide ladder guide rails, and more specifically to a graphite self-lubricating ladder guide rail for a metal mold. Background Art
[0002] Steel mold is a kind of mold. The main structure of most molds is steel material. The main structure of the steel mold is two mold parts that can be relatively close to or far away from each other. In some cases, it is necessary to design guide rails on the steel mold for guiding and limiting. However, some steel molds are heavy, so the friction resistance is large. The existing steel mold guide rails are prone to generate large friction when sliding, which causes the heat on the surface of the steel film to increase. Over time, it will affect the overall quality and service life of the steel mold. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a graphite self-lubricating trapezoidal guide rail for a metal mold, which has the advantage of small friction.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a graphite self-lubricating trapezoidal guide rail of a metal mold, comprising: a slide rail, a mounting hole and a first mounting groove are provided inside the slide rail, a rubber base is fixedly installed inside the first mounting groove, a first graphite column is fixedly installed above the rubber base, the first graphite column is located inside the mounting hole, and a height value of the first graphite column is slightly greater than a height value of the slide rail; a slide groove, a second mounting groove is provided at the bottom of the slide groove, a silicone storage bin is fixedly installed inside the second mounting groove, a connecting column is fixedly installed above the silicone storage bin, and an oil outlet hole is provided at the top of the connecting column.
[0005] The beneficial effect of adopting the above technical solution is that the slide rail is divided into two parts, the lower base width is greater than the upper width, and the front and rear sides of the upper part of the slide rail are inclined downward and connected to the lower part of the slide rail, thereby achieving a supporting effect. At the same time, the upper half of the slide rail protrudes, so that when the sliding device slides on its surface, it has a certain guiding effect on the sliding device.
[0006] As a preferred technical solution of the utility model, a screw hole is opened inside the slide rail, and there are two screw holes, which are respectively located at the left and right ends of the first graphite column.
[0007] The beneficial effect of adopting the above technical solution is that the two screw holes penetrate the interior of the slide rail from top to bottom. When the slide rail needs to be positioned and fixed, the two screw holes are engaged with the bolts, and then the bolts are fixed to the bottom components, thereby achieving the effect of easy installation and overall fixation of the slide rail.
[0008] As a preferred technical solution of the utility model, a fixing hole is fixedly installed inside the slide rail, a limiting ring is fixedly installed inside the fixing hole, a telescopic rod is fixedly installed inside the slide rail, a spring is sleeved on the outside of the telescopic rod, a connecting plate is fixedly installed on the outside of the telescopic rod, a second graphite column is fixedly installed on the side of the telescopic rod close to the connecting plate, and the limiting ring is located between the connecting plate and the second graphite column.
[0009] The beneficial effect of adopting the above technical solution is: the connection plate is limited by the limiting ring, so that the second graphite column can protrude slightly outward, so as to make the second graphite column contact with the sliding block that needs to slide as much as possible, thereby reducing the friction.
[0010] As a preferred technical solution of the utility model, there are multiple first mounting grooves and rubber bases, and the multiple rubber bases are respectively located inside the multiple first mounting grooves, and the multiple rubber bases are cylindrical and are all located inside the slide rail.
[0011] The beneficial effect of adopting the above technical solution is that the material of the multiple rubber bases is relatively soft and has a certain elasticity. At this time, since the height value of the first graphite column is slightly larger than the height value of the slide rail, when the top of the slide rail rubs and slides with the sliding device, it will contact the first graphite column, so that the first graphite column will be pressed downward when sliding and rubbing with the sliding device, thereby reducing the friction force and sharing a part of the supporting force of the slide rail, thereby achieving the effect of increasing the overall service life of the slide rail.
[0012] As a preferred technical solution of the utility model, there are two slide grooves, the two slide grooves are respectively located inside the slide rail, and the two slide grooves are respectively located on the front and rear sides of the first graphite column.
[0013] The beneficial effect of adopting the above technical solution is that a slider is slidably connected to the inside of the two slide grooves, and when the slider slides inside the slide groove, it will be limited by the slide groove, so that the sliding device above can be limited and supported, thereby achieving an overall supporting effect.
[0014] As a preferred technical solution of the utility model, there are multiple silica gel storage bins, the interiors of the multiple silica gel storage bins are hollow, and the multiple silica gel storage bins have a certain elasticity.
[0015] The beneficial effect of adopting the above technical solution is that a certain amount of lubricating oil can be stored inside the multiple silica gel storage bins, and when the slider slides inside the slide groove, the friction between the slider and the slide groove can be reduced, thereby increasing the smoothness of sliding.
[0016] As a preferred technical solution of the utility model, there are multiple connecting columns, and the multiple connecting columns are all located inside the second installation groove. The interiors of the multiple connecting columns are hollow and the tops are all provided with oil outlet holes.
[0017] The beneficial effect of adopting the above technical solution is that the top ends of the multiple connecting columns are slightly higher than the bottom end of the slide. When the courtesan slides with the slide, it will contact the top ends of the connecting columns, so that the bottom ends of the connecting columns are pressed downward, thereby squeezing the silicone storage bin at the bottom through the connecting columns, so that the lubricating oil inside the silicone storage bin will be squeezed into the interior of the slide, thereby achieving the goal of maintaining the lubrication of the interior of the slide at all times.
[0018] As a preferred technical solution of the utility model, there are multiple telescopic rods and springs, the multiple springs are all located inside the fixing holes, and the multiple springs all provide elastic force in the direction of the connecting plate. There are multiple second graphite columns, and the multiple second graphite columns are respectively located at the inclined parts on the front and rear sides of the upper part of the slide rail.
[0019] The beneficial effect of adopting the above technical solution is that after the second graphite column contacts the sliding device, it will first rub against the surface of the second graphite column. Due to the material effect of the second graphite column and the relatively smooth surface effect, the overall friction force will be greatly reduced, thereby preventing the large heat generated by long-term friction from causing more wear on the slide rail, thereby improving the overall service life of the slide rail.

[0027] like Figures 1 to 5 As shown, the utility model provides a graphite self-lubricating trapezoidal guide rail for a metal mold, comprising: a slide rail 1, a mounting hole 2 and a first mounting groove 3 are provided inside the slide rail 1, a rubber base 4 is fixedly installed inside the first mounting groove 3, a first graphite column 5 is fixedly installed above the rubber base 4, the first graphite column 5 is located inside the mounting hole 2, and a height value of the first graphite column 5 is slightly greater than a height value of the slide rail 1; a slide groove 13, a second mounting groove 14 is provided at the bottom of the slide groove 13, a silicone storage bin 15 is fixedly installed inside the second mounting groove 14, a connecting column 16 is fixedly installed above the silicone storage bin 15, and an oil outlet hole 17 is provided at the top of the connecting column 16.
[0028] The beneficial effect of adopting the above technical solution is that the slide rail 1 is divided into two parts, the lower base width is greater than the upper width, and the front and rear sides of the upper part of the slide rail 1 are inclined downward and connected to the lower part of the slide rail 1, thereby achieving a supporting effect. At the same time, the upper half of the slide rail 1 protrudes, so that when the sliding device slides on its surface, it has a certain guiding effect on the sliding device.
[0029] The interior of the slide rail 1 is provided with screw holes 6 , and there are two screw holes 6 , which are respectively located at the left and right ends of the first graphite column 5 .
[0030] The beneficial effect of adopting the above technical solution is that the two screw holes 6 penetrate the interior of the slide rail 1 from top to bottom. When the slide rail 1 needs to be positioned and fixed, the two screw holes 6 are engaged with the bolts, and then the bolts are fixed to the bottom components, thereby achieving the effect of facilitating installation and overall fixation of the slide rail 1.
[0031] Among them, a fixing hole 7 is fixedly installed inside the slide rail 1, a limiting ring 8 is fixedly installed inside the fixing hole 7, a telescopic rod 9 is fixedly installed inside the slide rail 1, a spring 10 is sleeved on the outside of the telescopic rod 9, a connecting plate 11 is fixedly installed on the outside of the telescopic rod 9, a second graphite column 12 is fixedly installed on the side of the telescopic rod 9 close to the connecting plate 11, and the limiting ring 8 is located between the connecting plate 11 and the second graphite column 12.
[0032] The beneficial effect of adopting the above technical solution is: the connection plate 11 is limited by the limiting ring 8, so that the second graphite column 12 can protrude slightly outward, so as to make the second graphite column 12 contact with the sliding block that needs to slide as much as possible, thereby reducing its friction.
[0033] There are multiple first installation grooves 3 and multiple rubber bases 4 , and the multiple rubber bases 4 are respectively located inside the multiple first installation grooves 3 . The multiple rubber bases 4 are cylindrical and are all located inside the slide rail 1 .
[0034] The beneficial effect of adopting the above technical solution is that the material of the multiple rubber bases 4 is relatively soft and has a certain elasticity. At this time, since the height value of the first graphite column 5 is slightly larger than the height value of the slide rail 1, when the top of the slide rail 1 rubs and slides with the sliding device, it will contact with the first graphite column 5, so that the first graphite column 5 will be pressed downward when sliding and rubbing with the sliding device, thereby reducing the friction force and sharing a part of the supporting force of the slide rail 1, thereby achieving the effect of increasing the overall service life of the slide rail 1.
[0035] There are two slide grooves 13 , the two slide grooves 13 are respectively located inside the slide rail 1 , and the two slide grooves 13 are respectively located at the front and rear sides of the first graphite column 5 .
[0036] The beneficial effect of adopting the above technical solution is that a slider is slidably connected to the inside of the two slide grooves 13, and when the slider slides inside the slide groove 13, it will be limited by the slide groove 13, so that the sliding device above can be limited and supported, thereby achieving an overall supporting effect.
[0037] There are multiple silica gel storage bins 15 , the interiors of the multiple silica gel storage bins 15 are all hollow, and the multiple silica gel storage bins 15 have a certain elasticity.
[0038] The beneficial effect of adopting the above technical solution is that a certain amount of lubricating oil can be stored inside the multiple silica gel storage bins 15, and when the slider slides inside the slide groove 13, the friction between the slider and the slide groove 13 can be reduced, thereby increasing the smoothness of sliding.
[0039] There are multiple connecting columns 16 , and the multiple connecting columns 16 are all located inside the second installation groove 14 . The interiors of the multiple connecting columns 16 are all hollow, and the tops of the multiple connecting columns 16 are all provided with oil outlet holes 17 .
[0040] The beneficial effect of adopting the above technical solution is that the top ends of the multiple connecting columns 16 are slightly higher than the bottom end of the slide groove 13. When the slider slides with the slide groove 13, it will contact the top ends of the connecting columns 16, so that the bottom ends of the connecting columns 16 are pressed downward, thereby squeezing the silicone storage bin 15 at the bottom through the connecting columns 16, so that the lubricating oil inside the silicone storage bin 15 will be squeezed into the interior of the slide groove 13, thereby achieving the goal of maintaining the lubrication inside the slide groove 13 at all times.
[0041] Among them, there are multiple telescopic rods 9 and springs 10, and the multiple springs 10 are all located inside the fixing hole 7, and the multiple springs 10 provide elastic force in the direction of the connecting plate 11. There are multiple second graphite columns 12, and the multiple second graphite columns 12 are respectively located at the inclined parts on the front and rear sides of the upper part of the slide rail 1.
[0042] The beneficial effect of adopting the above technical solution is that after the second graphite column 12 contacts the sliding device, it will first rub against the surface of the second graphite column 12, and due to the material effect of the second graphite column 12 and the relatively smooth surface effect, the overall friction force will be greatly reduced, thereby preventing the large heat generated by long-term friction from causing more wear on the slide rail 1, thereby improving the overall service life of the slide rail 1.
[0043] The working principle and use process of this utility model:
[0044] First, install the rubber base 4 carrying the first graphite column 5 into the first installation groove 3 and the installation hole 2, and fill the inside of the silica gel storage bin 15 with lubricating oil, and install it into the inside of the second installation groove 14, so that the internal structure of the slide rail 1 is completely assembled;
[0045] At this time, the bolts are engaged with the screw holes 6, and the slide rail 1 is fixed to the specified position and then fixed. The sliding device is placed above the screw holes 6 so that the screw holes 6 guide it. At the same time, a slider needs to be fixedly installed at the bottom of the sliding device to be slidably connected with the slide groove 13;
[0046] When the sliding device slides on the slide rail 1, it will rub against the first graphite column 5 and the second graphite column 12. At this time, since the rubber base 4 has a certain elasticity, the first graphite column 5 will be slightly lifted and lowered, and the second graphite column 12 will be extended and retracted through the telescopic rod 9, so that the first graphite column 5 and the second graphite column 12 will disperse part of the supporting force on the slide rail 1 during the friction. At the same time, since the materials of the first graphite column 5 and the second graphite column 12 have a certain wear resistance, and the friction force generated by the first graphite column 5 and the second graphite column 12 is small, the overall friction force will be reduced during sliding, so that the heat of the slide rail 1 is reduced, thereby achieving the effect of increasing the service life of the slide rail 1;
[0047] Finally, the slide groove 13 can limit the slider at the bottom of the sliding device, so that the sliding device can be limited up and down. At the same time, after the slider contacts the top of the connecting column 16, it will squeeze the connecting column 16 downward, so that the lubricating oil inside the silicone storage bin 15 is squeezed out into the slide groove 13 through the oil outlet 17, thereby increasing the lubrication degree and reducing the overall friction.
