Description

Technical Field

[0001] This invention relates to the field of die-casting technology for housing parts, and particularly to a die-casting mold for server housing parts. Background Technology

[0002] Die casting is an efficient method for producing structural components such as server casings. Its molds typically include a side core-pulling mechanism for forming lateral features. This mechanism generally consists of a slanted guide post fixed to the moving mold side and a slanted guide groove set on the slider, which drives the slider to reciprocate through the mold opening and closing action.

[0003] In existing technologies, to reduce friction and wear between the inclined guide post and the inclined slide groove, lubrication is often achieved by periodically applying lubricating oil manually or by setting simple oil channels on the mold. These methods provide basic lubrication to a certain extent.

[0004] However, the aforementioned existing lubrication methods have significant limitations. Manual lubrication relies on operators and carries the risk of uneven lubrication, improper intervals, or omissions, making it difficult to ensure consistent lubrication during each mold closing. Simple fixed oil channel structures, on the other hand, supply oil regardless of mold movement, failing to achieve dynamic lubrication. These factors collectively lead to wear and damage, as well as insufficient lubrication, in the contact area between the inclined guide post and the slider during long-term cyclic operation.

[0005] In summary, the existing lubrication methods of the side core-pulling mechanism of die-casting molds are insufficient in terms of continuity, accuracy and automation, which is a technical bottleneck affecting the mold life and the stability of casting quality. Summary of the Invention

[0006] The purpose of this invention is to provide a die-casting mold for server casing parts, featuring a lubrication pipe equipped with a liquid level sensor and an oil replenishment component. This lubrication pipe automatically detects and replenishes lubricating oil during mold closing. A pneumatically controlled sealing ring is installed at the lubrication pipe port, automatically expanding or contracting with the mold's opening and closing motion. By linking the power and pneumatic components with the mold closing action, the supply, distribution, and channel opening and closing of lubricating oil are automatically synchronized with the mold's opening and closing process. This provides several advantages.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a die-casting mold for server casing parts, comprising: The die-casting mold consists of a side-opening mold base one and a mold base two. A movable mold core is installed on mold base one, and a fixed mold core is installed on mold base two. The lubrication pipe is installed on the mold base and contains lubricating oil. An inclined guide post is installed inside the mold base and passes through the lubrication pipe and the mold base. A lubrication channel is provided on the outer wall of the inclined guide post. One end of the lubrication channel is located inside the lubrication pipe, and the other end of the lubrication channel extends to the outside of the mold base. The side slider is mounted on the fixed mold core. The side slider has an inclined groove for the insertion of the inclined guide post. During the mold closing / opening process, the inclined guide post pushes the side slider to slide back and forth along the fixed mold core. The sleeve is located at the end of the lubrication tube and is also penetrated by the inclined guide post. A sealing ring is provided on the inner circumferential surface of the sleeve where it contacts the inclined guide post, which expands when inflated and contracts when deflated. The sealing ring shrinks during the mold closing process of mold base one and mold base two, creating a gap between the sealing ring and the lubrication channel. The lubrication tube inside the lubrication tube flows into the inclined groove along the lubrication channel and the gap. The sealing ring expands during the mold opening process of mold base one and mold base two, sealing the lubrication channel.

[0008] As an optional implementation, the mold base is also provided with a power component that drives the inclined guide post to rotate during the mold closing process. The power component includes a telescopic rod and a telescopic spring. The telescopic spring is located inside the telescopic rod and is connected to a pressure sensor. The telescopic rod is installed on the mold base and is electrically connected to a motor that controls the rotation of the inclined guide post.

[0009] As an optional implementation, the telescopic rod includes a fixed cylinder and a movable cylinder. The movable cylinder is inserted into the fixed cylinder. During the mold closing process of mold base one and mold base two, mold base two deforms after squeezing the telescopic rod and the telescopic spring. After the pressure changes, the pressure sensor drives the motor connected to the inclined guide post to work.

[0010] As an optional implementation, a material storage groove is provided on the inner circumferential surface of the inclined groove, and the width of the material storage groove does not exceed 1 mm.

[0011] As an optional implementation, the mold base is also provided with an oil replenishment component connected to the lubrication pipe. The oil replenishment component includes an oil replenishment pipe and an oil replenishment pump. The oil replenishment pump is installed on the oil replenishment pipe. One end of the oil replenishment pipe is connected to the lubrication pipe, and the other end is connected to the lubricating fluid tank. A liquid level sensor is also provided inside the lubrication pipe.

[0012] As an optional implementation, the lubrication channel is spiral-shaped, and the width of the lubrication channel is less than the depth of the channel, with the width of the lubrication channel being less than 0.8 mm and the depth of the lubrication channel being less than 1.5 mm.

[0013] As an optional implementation, after the liquid level sensor detects that the liquid level is below the threshold, it drives the oil replenishment pump to work during the mold base one and mold base two mold closing process, in order to draw lubricating fluid and deliver it to the lubrication pipe.

[0014] As an optional implementation, the lubrication channel includes a spiral channel and a spiral sealing plate. The spiral channel is disposed on the outer wall of the inclined guide post, the spiral sealing plate seals the spiral channel, and an oil drain hole is provided on the spiral sealing plate facing the side slider of the inclined guide post. The groove width of the spiral channel is less than 5mm, and the diameter of the oil drain hole is the same as the groove width. The spiral sealing plate has a sealing groove for the expansion sealing ring to fill, which is used to seal the spiral channel.

[0015] As an optional implementation, the mold base is provided with a pneumatic component for controlling the expansion and contraction of the sealing ring. The pneumatic component includes a sealing tube, a return spring, a limiting rod, and an air pipe. A sliding sealing plate is provided inside the sealing tube. The sealing plate separates the upper sealing tube into cavity one and cavity two. The limiting rod connected to one end of the sealing plate extends out of cavity one and is located between mold base one and mold base two. The return spring is located in cavity two and is connected to the sealing plate and the sealing tube. One end of the air pipe is connected to the sealing ring, and the other end is connected to cavity one.

[0016] As an optional implementation, the length of the limiting rod extending out of the mold base is greater than the length of the inclined guide post extending out of the mold base.

[0017] The technical effects and advantages of this invention are as follows: 1. By incorporating a lubrication pipe equipped with a liquid level sensor and oil replenishment components, lubricating oil can be automatically detected and replenished during mold closing, ensuring a continuous and stable supply of lubricating fluid. Combined with the slanted guide post rotation drive and the spiral lubrication channels on its surface, lubricating oil can be actively delivered to the mating surfaces of the slanted guide post and the side slider, thereby forming an effective lubricating film during mold closing and helping to reduce friction and wear on the moving parts.

[0018] 2. A pneumatically controlled sealing ring is installed at the lubrication pipe port. This sealing ring automatically expands or contracts with the mold opening and closing. When the mold opens, the sealing ring expands to close the lubrication channel, reducing lubricant evaporation and contamination; when the mold closes, the sealing ring contracts to create a gap, ensuring smooth flow of lubricant. This helps maintain the cleanliness and performance of the lubricant and reduces dependence on the external environment.

[0019] 3. By linking the power and pneumatic components with the mold-closing action through mechanical structures such as telescopic rods and springs, the supply, distribution, and channel opening and closing of lubricating oil are automatically synchronized with the mold opening and closing process. This integrated linkage design simplifies the control system, improves the coordination and reliability of the actions, and helps ensure mold-closing accuracy and mold operation stability.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Referring to the figure, a die-casting mold for a server casing part includes: The die-casting mold 1 consists of a side-opening mold base 11 and a mold base 2 12. A moving mold core is installed on the mold base 11 and a fixed mold core is installed on the mold base 2 12. The moving mold core and the fixed mold core are detachably assembled on the mold base 11 and the mold base 2 12. Different moving mold cores and fixed mold cores can be replaced according to the production of different shell parts. Lubrication pipe 2 is installed on mold base 11. Lubrication pipe 2 stores lubricating oil. Mold base 11 is also equipped with an oil replenishment component 8 connected to lubrication pipe 2. The oil replenishment component 8 includes an oil replenishment pipe 81 and an oil replenishment pump 82. The oil replenishment pump 82 is installed on the oil replenishment pipe 81. One end of the oil replenishment pipe 81 is connected to lubrication pipe 2, and the other end is connected to the lubricating fluid tank. A liquid level sensor is also installed in lubrication pipe 2. After the liquid level sensor detects that the liquid level is lower than the threshold, it drives the oil replenishment pump 82 to work during the mold closing process of mold base 11 and mold base 2 12, so as to draw lubricating fluid and deliver it to lubrication pipe 2.

[0024] Side slider 4 is mounted on the fixed mold core. The side slider 4 has an inclined groove 41 for the inclined guide post 3 to be inserted. During the mold closing / opening process, the inclined guide post 3 pushes the side slider 4 to slide back and forth along the fixed mold core. The level of lubricating oil in the lubrication pipe 2 is detected by a liquid level sensor. When the level in the lubrication pipe 2 is lower than the set threshold, such as 1 cm, the lubricating oil in the lubrication pipe 2 is replenished. At the same time, the oil replenishment action is set to be performed during the mold base 11 and mold base 2 12 closing process. The basis is that when the mold base 11 and mold base 2 12 close, a gap is generated between the sealing ring 6 and the lubrication channel 31, the air pressure inside the lubrication pipe 2 is consistent with the outside air pressure, and the external lubricating oil can flow into the lubrication pipe 2.

[0025] In order to allow the lubricating oil in the lubrication pipe 2 to flow into the inclined groove 41 when the inclined guide post 3 is inserted into the inclined groove 41, thereby reducing the friction between the two and reducing the damage to the inclined guide post 3 and the inclined groove 41, a lubrication channel 31 and a power component 7 for driving the inclined guide post 3 to rotate are provided.

[0026] Specifically, the mold base 11 is also equipped with a power component 7 that drives the inclined guide post 3 to rotate during the mold closing process. The power component 7 includes a telescopic rod 71 and a telescopic spring 72. The telescopic spring 72 is located inside the telescopic rod 71 and is connected to a pressure sensor. The telescopic rod 71 is installed on the mold base 11 and is electrically connected to a motor that controls the rotation of the inclined guide post 3.

[0027] The telescopic rod 71 includes a fixed cylinder and a moving cylinder. The moving cylinder is inserted into the fixed cylinder. During the mold closing process of mold base 11 and mold base 2 12, mold base 2 12 deforms after squeezing the telescopic rod 71 and the telescopic spring 72. After the pressure changes, the pressure sensor drives the motor connected to the inclined guide post 3 to work.

[0028] When mold base 11 and mold base 2 12 are closed, mold base 2 12 will first contact the moving cylinder. Then, as the moving cylinder moves, the telescopic spring 72 will slowly compress and deform. At this time, the pressure of the telescopic spring 72 acting on the pressure sensor will gradually increase. At this time, the pressure sensor drives the motor to work, and the motor drives the inclined guide post 3 to rotate. The rotation speed of the inclined guide post 3 is set according to the requirements to avoid the lubricating oil being thrown out of the lubrication channel 31 due to excessive speed, while also allowing the lubricating fluid to flow along the lubrication channel 31.

[0029] Specifically, the inclined guide post 3 is installed inside the mold base 11 and passes through the lubrication pipe 2 and the mold base 11. A lubrication channel 31 is provided on the outer wall of the inclined guide post 3. One end of the lubrication channel 31 is located inside the lubrication pipe 2, and the other end of the lubrication channel 31 extends to the outside of the mold base 11. The lubrication channel 31 is spiral-shaped, and the groove width of the lubrication channel 31 is less than the groove depth. The groove width of the lubrication channel 31 is less than 0.8 mm, and the groove depth of the lubrication channel 31 is less than 1.5 mm.

[0030] The lubrication channel 31 is threaded and exposed on the outer wall of the inclined guide post 3. The depth and width of the lubrication channel 31 are designed to maximize capillary retention force and prevent the lubricating oil from being thrown out. The narrow slit of the lubrication channel 31 generates greater capillary pressure, which can more firmly adsorb the liquid in the lubrication channel 31. The lubrication channel 31 has sufficient depth to hold more liquid. Through the capillary effect of the lubrication channel 31, the lubricating fluid of the lubrication tube 2 is drawn into the lubrication channel 31. When the inclined guide post 3 rotates, the viscous force of the groove wall of the lubrication channel 31 will still drive the lubricating oil in the lubrication channel 31 to move along the spiral path.

[0031] Therefore, when mold base 11 and mold base 2 12 are closed, the inclined guide post 3 rotates to allow the lubricating fluid in the lubrication pipe 2 to flow into the inclined groove 41 through the lubrication channel 31, which also reduces the friction between the two. At the same time, since the inclined guide post 3 can rotate, it avoids the fact that the two sides of the inclined guide post 3 and the side slider 4 are the main force contact areas during the reciprocating movement of the inclined guide post 3. The friction caused by the long-term reciprocating movement will cause wear at the contact position, and the side slider 4 will not be able to accurately reach the designated position. This will cause the mold cavity enclosed by the side slider 4, the moving mold core and the fixed mold core to change, resulting in quality defects in the cast shell parts.

[0032] A sleeve 5 is located at the end of the lubrication pipe 2. The sleeve 5 is also penetrated by the inclined guide post 3. A sealing ring 6 is provided on the inner circumferential surface of the sleeve 5 where it contacts the inclined guide post 3. The sealing ring 6 shrinks during the mold closing process of mold base 11 and mold base 212, creating a gap between the sealing ring 6 and the lubrication channel 31. The lubrication pipe 2 flows into the inclined groove 41 along the lubrication channel 31 and the gap. A material storage groove 411 is provided on the inner circumferential surface of the inclined groove 41. The groove width of the material storage groove 411 does not exceed 1 mm. The material storage groove 411 is used to accommodate the flowing lubricating fluid. The material storage groove 411 is a continuous curved shape. The lubricating fluid flowing into the inclined groove 41 is stored in the storage tank 411. The inclined guide post 3 is inserted into the inclined groove 41. During the rotation of the inclined guide post 3, the liquid in the lubrication channel 31 comes into contact with the inner wall of the inclined groove 41. Moreover, when the lubrication channel 31 rotates with the inclined guide post 3, it can coat the lubricating fluid in the inclined groove 41 to the maximum extent. After being lubricated by the lubricating fluid, the friction between the two is reduced, avoiding damage to the surfaces of the two. At the same time, the lubricating fluid on the lubrication channel 31 comes into contact with the inclined groove 41. The sealing ring 6 expands during the mold opening process of the mold base 11 and the mold base 2 12, and the sealing ring 6 seals the lubrication channel 31.

[0033] In order to ensure that the lubricant can flow out from the lubrication pipe 2 while avoiding prolonged contact with the external environment, which would reduce the lubrication effect, a deformable sealing ring 6 is provided. When the mold base 11 and the mold base 2 12 are closed, the sealing ring 6 shrinks, and a gap is formed between the inclined guide post 3 and the sealing ring 6. During the rotation of the inclined guide post 3, the lubricant flows through the gap and into the inclined groove 41 along the lubrication channel 31.

[0034] Example 2: Referring to the figure, the difference between this example and Example 1 lies in the lubrication channel 31. The lubrication channel 31 in this example includes a spiral channel 311 and a spiral sealing plate 312. The spiral channel 311 is disposed on the outer wall of the inclined guide post 3. The spiral sealing plate 312 seals the spiral channel 311, and an oil drain hole is provided on the spiral sealing plate 312 facing the side slider 4 of the inclined guide post 3. The groove width of the spiral channel 311 is less than 5mm, and the diameter of the oil drain hole is the same as the groove width. A sealing groove is provided on the spiral sealing plate 312, which is filled by the expanding sealing ring 6 to seal the spiral channel 311.

[0035] Since the groove of the lubrication channel 31 in Embodiment 1 is exposed, it is limited by centrifugal force, which limits the rotation speed of the inclined guide post 3. In order to remove the limitation, a structure is set up to seal the spiral channel 311 by the spiral sealing plate 312, and the size of the spiral channel 311 is increased. The lubricating oil is fed into the inclined groove 41 after rotation in the spiral channel 311, and then discharged from the oil drain hole to lubricate the inclined guide post 3 and the inclined groove 41.

[0036] In both Embodiment 1 and Embodiment 2, the sealing ring 6 is controlled by the pneumatic component 9. Specifically, the mold base 11 is equipped with a pneumatic component 9 for controlling the expansion and contraction of the sealing ring 6. The pneumatic component 9 includes a sealing tube 91, a return spring 92, a limiting rod 93, and an air pipe 94. A sliding sealing plate 95 is provided inside the sealing tube 91, which divides the upper sealing tube 91 into cavity one and cavity two. Cavity two is connected to the outside. The limiting rod 93, connected to one end of the sealing plate 95, extends out of cavity one and is located between mold base 11 and mold base 2 12. The return spring 92 is located in cavity two and is connected to the sealing plate 95 and the sealing tube 91. One end of the air pipe 94 is connected to the sealing ring 6, and the other end is connected to cavity one. The length of the limiting rod 93 extending out of mold base 11 is greater than the length of the inclined guide post 3 extending out of mold base 11.

[0037] During the mold closing process, the mold will first contact the limiting rod 93 and move towards the sealing tube 91 against the limiting rod 93, synchronously driving the sealing plate 95 to move. As the sealing plate 95 moves, the volume of cavity one increases while the volume of cavity two decreases, compressing the return spring 92. Under the action of pressure, the gas in the sealing ring 6 flows into cavity one through the air pipe 94, and the sealing ring 6 shrinks, so as not to cut off the lubrication channel 31, allowing the lubricating oil to flow out from the lubrication pipe 2.

[0038] As the mold opens, under the action of the return spring 92, the volume of cavity one shrinks while the volume of cavity two increases. The gas in cavity one flows into the sealing ring 6 through the air pipe 94, and the sealing ring 6 expands to cut off the lubrication channel 31.

[0039] Example 3: Referring to the figure, the difference between this example and Examples 1 and 2 lies in the pneumatic component 9. To save costs, the pneumatic component 9 can also be combined with the power component 7. Specifically, the power component 7 includes a telescopic rod 71, a telescopic spring 72, and a partition plate 73. The telescopic rod 71 includes a fixed cylinder and a moving cylinder. One end of the moving cylinder is inserted into the fixed cylinder and connected to the partition plate 73. The partition plate 73 divides the interior of the fixed cylinder into cavity one and cavity two. Cavity one is connected to the sealing ring 6 through an air pipe 94. One side of the partition plate 73 is connected to the pressure sensor through the telescopic spring 72. When mold base 11 and mold base 2 12 are closed, mold base 2 12 will first contact the moving cylinder. Then, as the moving cylinder and partition plate 73 move, the volume of cavity 1 increases while the volume of cavity 2 decreases. Under the action of pressure, the gas in the sealing ring 6 flows into cavity 1 through the air pipe 94, and the sealing ring 6 shrinks. During the movement of partition plate 73, the telescopic spring 72 slowly compresses and transmits the pressure to the pressure sensor, triggering the motor to work and realize the rotation of the inclined guide column 3, so that the lubricating oil flows into the inclined groove 41 from the lubrication channel 31.

[0040] As the mold opens, under the action of the extension spring 72, the volume of cavity one shrinks while the volume of cavity two increases. The gas in cavity one flows into the sealing ring 6 through the air pipe 94, and the sealing ring 6 expands to cut off the lubrication channel 31.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention 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 invention should be included within the protection scope of the present invention.
