Description

Technical Field

[0001] This utility model belongs to the field of mold manufacturing technology, specifically a toy mold with a self-lubricating slider structure. Background Technology

[0002] In the manufacturing and use of toy molds, the performance of the slider structure directly affects the mold's operating efficiency and service life. Currently, most slider structures on the market adopt traditional mechanical designs, and their lubrication usually relies on externally added lubricating oil. However, this method requires regular maintenance, and the lubricating oil is easily contaminated or lost, leading to increased slider friction resistance and affecting the mold's stability and working efficiency. In addition, traditional slider structures are prone to wear and tear during long-term use, resulting in decreased precision and further increasing maintenance costs and time investment.

[0003] For example, the specification of "A High-Precision Mold Slider Positioning Mechanism" disclosed in patent application 202320261948.7 states that it includes multiple sliders, a large disk that restricts the direction of slider movement, and multiple fan-shaped pressure strips distributed on both sides of the sliders for positioning. The large disk has several slider guide grooves spaced circumferentially at its upper end for slider movement. The upper end of the large disk between each slider is fan-shaped and fixedly connected to the fan-shaped pressure strips. The inner ends of the fan-shaped pressure strips protrude from the top fan-shaped surface of the large disk and form pressure strip slopes on both sides. Positioning slopes that cooperate with the pressure strip slopes are provided on both sides of the slider. At the moment the slider closes, the pressure strip slopes guide and position the slider through the slopes on the slider, ensuring both smooth slider movement and accurate slider position after closure. However, this high-precision mold slider positioning mechanism has a high processing threshold, low assembly tolerance, and stringent environmental and equipment requirements for interference fit. Furthermore, it relies on specialized equipment, making it difficult to guarantee batch consistency and widespread adoption.

[0004] Therefore, we made improvements and proposed a toy mold with a self-lubricating slider structure. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing toy mold slider structures, such as reliance on externally added lubricating oil for lubrication, high maintenance frequency, limited lubrication effect, and decreased precision after long-term use.

[0006] To achieve the above objectives, this utility model provides a toy mold with a self-lubricating slider structure, including a slider body and a lubrication assembly. The slider body is connected to the mold base via a guide member, and the lubrication assembly is located inside the slider body and communicates with the sliding contact surface. Positioning members are provided on both sides of the slider body to limit the offset of the slider body during movement. The lubrication assembly includes an oil storage unit and a flow guiding unit. The oil storage unit is fixed inside the slider body, and the flow guiding unit delivers the lubricating medium in the oil storage unit to the sliding contact surface of the slider body.

[0007] The oil storage unit includes a sealed cavity filled with a solid lubricating material made of graphite and polytetrafluoroethylene, which has a low coefficient of friction and good wear resistance. The top of the sealed cavity is provided with a feeding port, which is sealed by a threaded cap to allow for replenishment of lubricating material when necessary. The bottom of the sealed cavity is provided with several evenly distributed oil outlet holes, which are connected to the flow guiding unit.

[0008] The flow guiding unit includes an oil guiding groove and a capillary tube. The oil guiding groove is located on the inner wall of the slider body. One end of the capillary tube is connected to the oil outlet, and the other end extends to the sliding contact surface of the slider body. The capillary tube is made of porous ceramic material, and microporous channels are formed inside it, which can continuously transport the lubricating medium after the solid lubricating material is decomposed to the sliding contact surface through capillary action. The width of the oil guiding groove is 1-2 mm and the depth is 0.5-1 mm to ensure that the lubricating medium can be evenly distributed inside the slider body.

[0009] As a preferred technical solution of this application, the sliding contact surface of the slider body is provided with a number of micro grooves, the depth of which is 0.1-0.3 mm and the width of which is 0.5-1 mm; the micro grooves are evenly distributed along the sliding direction and are used to store the lubricating medium delivered from the guide unit, and to evenly coat the lubricating medium on the sliding contact surface during the movement of the slider.

[0010] As a preferred technical solution of this application, the guide component includes two parallel guide rails, which are fixed on the mold base. The bottom of the slider body is provided with a groove that mates with the guide rails. The inner wall of the groove is provided with a wear-resistant coating, which is made of titanium nitride material and has a thickness of 0.05-0.1 mm, to improve the wear resistance of the groove and reduce frictional resistance.

[0011] As a preferred technical solution of this application, the positioning component includes two symmetrically arranged limiting plates. The limiting plates are fixed to both sides of the slider body by bolts. An elastic pad is provided on the inner side of the limiting plate. The elastic pad is made of silicone material and has a thickness of 1-2 mm. The elastic pad contacts the guide rail during the movement of the slider body and plays a role in buffering and shock absorption, while preventing the slider body from shifting due to vibration.

[0012] As a preferred technical solution of this application, the top of the slider body is provided with a heat sink, which is made of aluminum alloy and its surface is anodized to improve corrosion resistance; the height of the heat sink is 5-10 mm, the width is 10-15 mm, and the spacing between adjacent heat sinks is 2-3 mm; the heat sink is fixed to the top of the slider body by screws and is used to dissipate the heat generated by friction during the operation of the slider.

[0013] As a preferred technical solution of this application, mounting plates are provided on both sides of the mold base. The mounting plates are fixed to the mold base by welding. The surface of the mounting plates is provided with mounting holes with a diameter of 8-10 mm, which are used to fix the mold base to the worktable. The thickness of the mounting plates is 5-8 mm and the material is stainless steel to improve the overall strength and stability of the mold base.

[0014] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0015] By designing an oil storage unit and a flow guiding unit, and utilizing the properties of solid lubricating materials and the delivery capacity of capillary tubes, the self-lubricating function of the slider structure is achieved, reducing the need for external maintenance. By setting micro-grooves on the sliding contact surface of the slider body, the uniformity of lubricant distribution is further improved, and frictional resistance is reduced. By setting a wear-resistant coating on the inner wall of the groove and setting a heat sink on the top of the slider body, the service life of the slider structure is extended and the operational stability is improved. Through the design of the positioning component, the displacement of the slider body during movement is effectively prevented, ensuring the machining accuracy of the mold.

[0016] This utility model, through the above-described structural design, solves the problems of existing slider structures, such as reliance on externally added lubricating oil for lubrication, high maintenance frequency, limited lubrication effect, and decreased accuracy after long-term use. It has significant inventiveness, novelty, and practicality. Attached Figure Description

[0024] This utility model relates to a toy mold with a self-lubricating slider structure, and its specific implementation is described in detail with reference to the accompanying drawings. Figure 1 As shown, the toy mold includes a slider body 1 and a mold base 2. The slider body 1 is connected to the mold base 2 via a guide 7. The guide 7 includes two parallel guide rails 8, which are fixed to the mold base 2. The bottom of the slider body 1 has a groove 9 that mates with the guide rails 8. The inner wall of the groove 9 is coated with a wear-resistant coating made of titanium nitride material with a thickness of 0.05-0.1 mm. The slider body 1 has a lubrication assembly inside, which includes an oil storage unit 3 and a flow guiding unit 4. The oil storage unit 3 is fixed inside the slider body 1, and the flow guiding unit 4 delivers the lubricating medium in the oil storage unit 3 to the sliding contact surface 5 of the slider body 1. Positioning components 10 are also provided on both sides of the slider body 1. The positioning components 10 include two symmetrically arranged limiting plates 11, which are fixed to both sides of the slider body 1 by bolts. The inner side of the limiting plates 11 is provided with an elastic gasket 12 made of silicone material with a thickness of 1-2 mm.

[0025] like Figure 2As shown, the sliding contact surface 5 of the slider body 1 is provided with several micro-grooves 6, which are evenly distributed along the sliding direction, with a depth of 0.1-0.3 mm and a width of 0.5-1 mm. These micro-grooves 6 are used to store the lubricating medium delivered from the flow guiding unit 4 and to evenly coat the lubricating medium on the sliding contact surface 5 during the slider's movement. The oil storage unit 3 includes a sealed cavity filled with solid lubricating material, which is made of a mixture of graphite and polytetrafluoroethylene. The top of the sealed cavity is provided with a feeding port, which is sealed by a threaded cap. The bottom of the sealed cavity is provided with several evenly distributed oil outlets, which are connected to the flow guiding unit 4. The flow guiding unit 4 includes an oil guide groove and a capillary tube. The oil guide groove is located on the inner wall of the slider body 1. One end of the capillary tube is connected to the oil outlet, and the other end extends to the sliding contact surface 5 of the slider body 1. The capillary tube is made of porous ceramic material, and its interior forms microporous channels, which can continuously deliver the lubricating medium after the solid lubricating material is decomposed to the sliding contact surface 5 through capillary action. The width of the oil guide groove is 1-2 mm and the depth is 0.5-1 mm to ensure that the lubricating medium can be evenly distributed inside the slider body 1.

[0026] like Figure 3 As shown, the sealed cavity of the oil storage unit 3, the oil outlet, and the capillary structure of the flow guiding unit 4 are further magnified. The oil outlets in the sealed cavity are evenly distributed, each with a diameter of 0.5-1 mm. The number of oil outlets is adjusted according to the size of the slider body 1 to ensure that the lubricating medium can be evenly distributed to the sliding contact surface 5. The length of the capillary is designed according to the internal structure of the slider body 1, and the distance between its end and the sliding contact surface 5 is 0.5-1 mm to ensure that the lubricating medium can directly act on the sliding contact surface 5. The micro-channel diameter of the capillary is 0.1-0.2 mm, which can effectively control the flow rate of the lubricating medium and avoid excessive or insufficient flow.

[0027] like Figure 4 As shown, positioning components 10 are provided on both sides of the slider body 1. Each positioning component 10 includes a limiting plate 11 and an elastic washer 12. The limiting plate 11 is fixed to both sides of the slider body 1 with bolts. An elastic washer 12 is provided on the inner side of the limiting plate 11. The elastic washer 12 contacts the guide rail 8 during the movement of the slider body 1, providing cushioning and shock absorption. The thickness of the limiting plate 11 is 2-3 mm, the thickness of the elastic washer 12 is 1-2 mm, and the gap between the limiting plate 11 and the guide rail 8 is 0.5-1 mm to ensure that the slider body 1 does not shift during movement. A heat sink 13 is provided on the top of the slider body 1. The heat sink 13 is made of aluminum alloy, with an anodized surface, a height of 5-10 mm, a width of 10-15 mm, and a spacing of 2-3 mm between adjacent heat sinks 13. The heat sink 13 is fixed to the top of the slider body 1 with screws to dissipate heat generated by friction.

[0028] like Figure 5 As shown, mounting plates 14 are provided on both sides of the mold base 2. The mounting plates 14 are fixed to the mold base 2 by welding. The surface of the mounting plates 14 has mounting holes 15 with a diameter of 8-10 mm, used to fix the mold base 2 to the worktable. The thickness of the mounting plates 14 is 5-8 mm, and the material is stainless steel to improve the overall strength and stability of the mold base 2. The guide rail 8 of the guide component 7 is fixed to the mold base 2 by bolts. The length of the guide rail 8 is designed according to the movement range of the slider body 1. The width of the guide rail 8 is 10-15 mm, and the height is 5-8 mm. The surface of the guide rail 8 is hardened to a hardness of HRC50 or higher to improve its wear resistance. The width of the slide groove 9 is 10-15 mm, the depth is 5-8 mm, and the gap between the slide groove 9 and the guide rail 8 is 0.1-0.2 mm to ensure that the slider body 1 can slide smoothly on the guide rail 8.

[0029] In actual operation, the slider body 1 reciprocates via the guide rail 8 of the guide component 7. When the slider body 1 begins to move, the solid lubricating material in the oil storage unit 3 gradually decomposes under the movement pressure of the slider body 1, and the lubricating medium enters the oil guide groove of the guide unit 4 through the oil outlet at the bottom of the sealed cavity. The oil guide groove guides the lubricating medium to the capillary, and the capillary delivers the lubricating medium to the sliding contact surface 5 through its internal microporous channels. The micro-grooves 6 on the sliding contact surface 5 store the lubricating medium and evenly coat it, thereby reducing the frictional resistance between the slider body 1 and the guide rail 8. The limiting plate 11 and the elastic pad 12 play a role in buffering and shock absorption during the movement of the slider body 1, while preventing the slider body 1 from shifting due to vibration. The heat sink 13 dissipates the heat generated by friction during the operation of the slider body 1, preventing the performance of the slider body 1 from deteriorating due to excessive temperature.

[0030] The mold base 2 is fixed to the worktable by the mounting plate 14. The mounting holes 15 of the mounting plate 14 are connected to the worktable by bolts to ensure the stability of the mold base 2. The guide rail 8 of the guide component 7 is fixed to the mold base 2 by bolts. The slide groove 9 of the slider body 1 cooperates with the guide rail 8. The wear-resistant coating on the inner wall of the slide groove 9 further reduces the frictional resistance between the slider body 1 and the guide rail 8. The top of the sealed cavity of the oil storage unit 3 is provided with a feeding port. When the solid lubricating material is exhausted, the lubricating material can be replenished through the feeding port to ensure that the self-lubricating function of the slider body 1 continues to be effective.

[0031] Through the above structural design, the slider body 1 achieves self-lubrication during movement, reducing the need for external maintenance. The micro-grooves 6 on the sliding contact surface 5 improve the uniformity of lubricant distribution and further reduce frictional resistance. The wear-resistant coating on the inner wall of the groove 9 and the heat sink 13 on the top of the slider body 1 extend the service life of the slider structure and improve operational stability. The design of the positioning component 10 effectively prevents the slider body 1 from shifting during movement, ensuring the machining accuracy of the mold.

[0032] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0033] In practical applications, the slider body 1 is fixed to the worktable by the mounting plate 14, and the mounting holes 15 of the mounting plate 14 are connected to the worktable by bolts, thereby ensuring the stability of the mold base 2. The guide rail 8 of the guide component 7 is fixed to the mold base 2 by bolts, and the sliding groove 9 of the slider body 1 cooperates with the guide rail 8. When the slider body 1 begins to reciprocate along the guide rail 8, the solid lubricating material in the oil storage unit 3 is gradually decomposed into a lubricating medium by the pressure generated by the movement of the slider body 1. This lubricating medium enters the oil guide groove of the guide unit 4 through the oil outlet at the bottom of the sealed cavity, and is then guided to the capillary along the oil guide groove. Since the capillary is made of porous ceramic material, its internal microporous channels can continuously deliver the lubricating medium to the sliding contact surface 5 through capillary action. The micro-grooves 6 on the sliding contact surface 5 store the lubricating medium and are uniformly coated on the sliding contact surface 5 during the movement of the slider body 1, thereby effectively reducing the frictional resistance between the slider body 1 and the guide rail 8.

[0034] During the movement of the slider body 1, the limiting plate 11 and the elastic washer 12 play important roles. The limiting plate 11 is fixed to both sides of the slider body 1 with bolts. The elastic washer 12 on its inner side is made of silicone material. When the slider body 1 moves, it contacts the guide rail 8, which plays a role in buffering and shock absorption, and at the same time prevents the slider body 1 from shifting due to vibration. The gap between the limiting plate 11 and the guide rail 8 is designed to be 0.5-1 mm. This gap range can ensure that the slider body 1 slides smoothly on the guide rail 8, and avoid the problem of displacement caused by excessive gap.

[0035] As the slider body 1 continues to operate, the heat generated by friction is dissipated through the heat sink 13. The heat sink 13 is made of aluminum alloy, and its surface is anodized to improve corrosion resistance. It is 5-10 mm high, 10-15 mm wide, and the spacing between adjacent heat sinks 13 is 2-3 mm. The heat sink 13 is fixed to the top of the slider body 1 with screws, which can dissipate heat in a timely manner during the operation of the slider and prevent the performance of the slider body 1 from deteriorating due to excessive temperature.

[0036] During long-term use, the wear-resistant coating on the inner wall of the groove 9 further reduces the frictional resistance between the slider body 1 and the guide rail 8. This wear-resistant coating is made of titanium nitride material with a thickness of 0.05-0.1 mm, which can significantly improve the wear resistance of the groove 9 and extend the service life of the slider structure. At the same time, the top of the sealed cavity of the oil storage unit 3 is provided with a feeding port. When the solid lubricating material is exhausted, the lubricating material can be replenished through the feeding port to ensure that the self-lubricating function of the slider body 1 remains effective.

[0037] Through the above structural design, the slider body 1 achieves self-lubrication during movement, reducing the need for external maintenance. The micro-grooves 6 on the sliding contact surface 5 improve the uniformity of lubricant distribution and further reduce frictional resistance. The wear-resistant coating on the inner wall of the groove 9 and the heat sink 13 on the top of the slider body 1 extend the service life of the slider structure and improve operational stability. The design of the positioning component 10 effectively prevents the slider body 1 from shifting during movement, ensuring the machining accuracy of the mold.

[0038] In summary, this utility model, through reasonable structural design and material selection, solves the problems of existing slider structures, such as reliance on externally added lubricating oil, high maintenance frequency, limited lubrication effect, and decreased accuracy after long-term use, and has significant technical effects and practicality.
