Description

Technical Field

[0001] This invention relates to the field of die casting technology, and more specifically, to a metal die casting. Background Technology

[0002] Die casting is a metal casting process characterized by applying high pressure to molten metal within a mold cavity. Die castings are parts produced under pressure. Using a die casting machine equipped with a casting mold, molten metal such as copper, zinc, aluminum, or aluminum alloys is poured into the machine's feed inlet. The machine then presses and casts the metal into copper, zinc, aluminum, or aluminum alloy parts of the shape and size defined by the mold. These parts are commonly called die castings. Die castings are increasingly widely used, with large-scale applications in the automotive industry.

[0003] The wheel hub is the part of the wheel where the axle is mounted; it's commonly referred to as the "wheel rim" or "wheel wheel." The wheel hub consists of five main components: the rim, spokes, offset, flange, and groove. The rim mates with the tire and supports the wheel; the spokes connect to the rim and support the wheel itself.

[0004] In existing technology, water tends to accumulate on the inside of the wheel hub during rain or washing, and the load-bearing capacity of the wheel hub needs to be improved. In addition, the rim and spokes are integrated, which reduces the reuse rate of the wheel hub components. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a metal die-casting part that improves the load strength of the spoke assembly by utilizing the mutual compression and limiting between the ring plate and the arc plate, and further enhances the load strength of the hub by employing a double-position reinforcing rib ring design. Simultaneously, a water guide platform guides water from the inner side of the rim to be discharged through the drainage groove or water leakage mesh on the reinforcing rib ring, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal die-casting part, including a rim and a mounting plate concentrically arranged with the rim, wherein the surface of the mounting plate has six mounting holes evenly distributed in a ring, and a valve hole is provided on the inner circumferential surface of the rim near the end of the mounting plate. Reinforcing rib rings are provided at both ends of the inner circumferential surface of the rim. Two snap-fit ​​mechanisms are provided between the reinforcing rib rings and the rim, which are axially symmetrical about the axis of the rim. A spoke assembly is fixed between the inner circumferential surface of the reinforcing rib rings and the outer circumferential surface of the mounting plate.

[0007] The snap-fit ​​mechanism includes a slot on the outer circumferential surface of the reinforcing rib ring and a slot on the rim surface. A connecting groove, arranged in a cross shape, is provided on the inner circumferential surface of the rim corresponding to the slot. A spring is fixedly connected to the inner end face of the connecting groove. A snap-fit ​​bar is fixedly connected to the end of the spring facing the slot. A wedge-shaped groove is provided through the end of the snap-fit ​​bar away from the slot. A wedge-shaped insert is movably inserted into the slot. U-shaped frames are fixedly provided on both sides of the slot on the rim surface. A sealing plate is movably inserted between the two U-shaped frames. A straight plate is fixedly provided at the end of the sealing plate away from the rim's central axis. A guide rod is fixedly provided at the middle edge of the side of the straight plate facing the rim's central axis. The end of the guide rod away from the straight plate movably passes through the U-shaped frame adjacent to the straight plate. A spring is movably sleeved on the outer circumferential surface of the guide rod near the straight plate, and both ends of the spring are fixedly connected to the opposite sides of the adjacent U-shaped frame and the straight plate.

[0008] The spoke assembly includes six sets of annularly distributed ring plates and six sets of annularly distributed arc plates, with the ring plates and arc plates alternating. The outer circumferential surface of the ring plates is tangent to the inner circumferential surface of the reinforcing rib ring and the outer circumferential surface of the mounting plate, and they are fixedly connected.

[0009] The beneficial effects of adopting the above-mentioned further solutions are: it can enhance the load-bearing capacity of the wheel hub while reducing the self-weight of the wheel hub, and allow for quick assembly and disassembly of the reinforcing rib rings connecting the spoke assemblies.

[0010] In a preferred embodiment, the outer circumferential surfaces of the two reinforcing ribs are provided with six drainage slots that are evenly distributed in a ring.

[0011] The beneficial effect of adopting the above-mentioned further solution is that it can guide the water accumulated on the inside of the wheel rim to drain quickly.

[0012] In a preferred embodiment, each group of the arc plates is provided with two, and the opposite sides of the two arc plates in each group are both concave.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the gap between two adjacent ring plates can be filled to enhance the load strength between adjacent spoke units.

[0014] In a preferred embodiment, a water-guiding arc block is fixedly provided on the opposite side of the two reinforcing rib rings at a position between two adjacent drainage outlets, and the side of the water-guiding arc block facing the center of the reinforcing rib ring at its location is set as a concave arc surface with a V-shaped structure.

[0015] The beneficial effect of adopting the above-mentioned further solution is that it can guide the accumulated water towards the drainage outlet and flow to the outside of the wheel hub.

[0016] In a preferred embodiment, a ring-shaped water guide platform is fixedly provided on the inner circumferential surface of the rim. The inner circumferential surface of the water guide platform is configured as a convex arc surface in the direction of the center of the rim. The edges of both ends of the water guide platform coincide with the inner edges of the reinforcing rib ring at the corresponding ends.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it can guide the water accumulated on the inside of the rim to flow to the reinforcing ribs on both sides, thus preventing water accumulation on the inside of the rim.

[0018] In a preferred embodiment, a plurality of drainage mesh holes, arranged parallel to the axis of the reinforcing rib ring, can be formed through the surface of the reinforcing rib ring.

[0019] The beneficial effect of adopting the above-mentioned further solution is that it can guide the water accumulated on the inside of the wheel rim to drain quickly.

[0020] In a preferred embodiment, multiple ventilation slots may be provided through the surfaces of both the ring plate and the arc plate.

[0021] The beneficial effects of adopting the above-mentioned further solutions are: it can increase the contact area between the spoke assembly and the air, allowing the flowing air to dissipate heat from the hub, making the hub less prone to high temperatures, and improving the safety of hub use.

[0022] The technical effects and advantages of this invention are as follows:

[0023] This invention sets the spoke assembly as a closed ring structure formed by alternating ring plates and arc plates connected at the ends. This not only reduces the weight of the spoke assembly and increases the contact area between the hub and the air, but also improves the load strength of the spoke assembly by using the mutual compression and limiting between the ring plates and arc plates. Furthermore, the design of double-reinforcing rib rings greatly improves the load strength of the hub.

[0024] This invention, by setting a snap-fit ​​mechanism, allows for quick assembly and disassembly of the reinforcing rib ring connecting the wheel spoke assembly, thereby improving the reuse rate of wheel hub components.

[0025] This invention provides a reinforcing rib ring with drainage slots or water-leaking mesh holes, and a water-guiding platform with a raised arc surface on the inner circumferential surface of the rim, which can effectively guide the water accumulated inside the rim to drain quickly and avoid water accumulation.

[0026] 3. This invention sets the spoke assembly as a closed ring structure consisting of alternating ring plates and arc plates connected at the ends. Multiple through-hole ventilation slots are provided on each ring plate and arc plate of the spoke assembly. This not only further reduces the weight of the spoke assembly, but also increases the contact area between the spoke assembly and the air, allowing the flowing air to quickly dissipate heat from the hub, making the hub less prone to high temperatures and improving the safety of the hub.

In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0040] Example 1

[0041] Refer to the instruction manual appendix Figure 1 and 5 -8. A metal die-casting part according to an embodiment of the present invention includes a rim 1 and a mounting plate 2 concentrically arranged with the rim 1. The surface of the mounting plate 2 has six mounting holes 3 evenly distributed in a ring. A valve hole 10 is provided on the inner circumferential surface of the rim 1 near the end of the mounting plate 2. Reinforcing rib rings 5 ​​are provided at both ends of the inner circumferential surface of the rim 1. Two snap-fit ​​mechanisms 12 are provided between the reinforcing rib rings 5 ​​and the rim 1, which are axially symmetrical about the axis of the rim 1. A spoke assembly 4 is fixed between the inner circumferential surface of the reinforcing rib ring 5 and the outer circumferential surface of the mounting plate 2.

[0042] The locking mechanism 12 includes a slot 121 formed on the outer circumferential surface of the reinforcing rib ring 5 and a slot 122 formed on the surface of the rim 1. A connecting groove 123, which is cross-shaped and communicates with the slot 122, is formed on the inner circumferential surface of the rim 1 at the position corresponding to the slot 121. A spring 124 is fixedly connected to the inner end face of the connecting groove 123. A locking strip 125 is fixedly connected to the end of the spring 124 facing the slot 121. A wedge-shaped groove 126 is formed through the end of the locking strip 125 away from the slot 121. A wedge-shaped insert 127 is movably inserted into the slot 122. Both sides of the slot 122 on the surface of the rim 1 are fixedly provided with... There is a U-shaped frame 128, and a sealing plate 129 is movably inserted between the two U-shaped frames 128. A straight plate 1210 is fixedly installed at the end of the sealing plate 129 that is off the central axis of the rim 1. A guide rod 1211 is fixedly installed at the middle edge of the side of the straight plate 1210 facing the central axis of the rim 1. The end of the guide rod 1211 away from the straight plate 1210 movably passes through the U-shaped frame 128 that is adjacent to the straight plate 1210. A spring 1212 is movably sleeved on the outer circumference of the guide rod 1211 near the straight plate 1210, and the two ends of the spring 1212 are respectively fixedly connected to the opposite sides of the adjacent U-shaped frame 128 and the straight plate 1210.

[0043] The spoke assembly 4 includes six sets of annularly distributed ring plates 41 and six sets of annularly distributed arc plates 42, with the ring plates 41 and arc plates 42 arranged alternately. The outer circumferential surface of the ring plates 41 is tangent to the inner circumferential surface of the reinforcing rib ring 5 and the outer circumferential surface of the mounting plate 2, and is fixedly connected. Each set of arc plates 42 has two, and the opposite sides of the two arc plates 42 in each set are recessed.

[0044] Furthermore, the outer circumferential surfaces of the two reinforcing rib rings 5 ​​are provided with six drainage slots 6 that are evenly distributed in a ring shape.

[0045] Furthermore, water-guiding arc blocks 8 are fixedly provided on the opposite side of the two reinforcing rib rings 5 ​​at the position between the two adjacent drainage slots 6. The side of the water-guiding arc block 8 facing the center of the reinforcing rib ring 5 at its location is set as a concave arc surface with a V-shaped structure.

[0046] Furthermore, a ring-shaped water guide platform 11 is fixedly provided on the inner circumferential surface of the rim 1. The inner circumferential surface of the water guide platform 11 is configured as a convex arc surface in the direction of the center position of the rim 1. The edge positions of both ends of the water guide platform 11 coincide with the inner edge position of the reinforcing rib ring 5 at the same end.

[0047] It should be noted that, in use, the die-cast wheel hub integrates the rim 1, mounting plate 2, spoke assembly 4, reinforcing rib ring 5, and water guide platform 11 into a single die-cast component. When encountering rain or a washing vehicle, the inner circumferential surface of the water guide platform 11 is designed as a convex arc surface towards the center of the rim 1, and the outer circumferential surface of the reinforcing rib ring 5 has six evenly distributed annular drainage slots 6. A water guide arc block 8 is positioned on one side of the reinforcing rib ring 5 between two adjacent drainage slots 6, with the side of the water guide arc block 8 facing the center of the reinforcing rib ring 5 having a V-shaped concave arc surface. This design guides water falling inside the rim 1 towards the drainage channel. Water is collected at six inlets and discharged through the lowest point of the drainage outlet 6. Meanwhile, the spoke assembly 4 is designed as a closed ring structure formed by alternating ring plates 41 and arc plates 42. This not only reduces the weight of the spoke assembly 4, but also increases the load-bearing capacity of the spoke assembly 4 by using the mutual compression and limiting between the ring plates 41 and arc plates 42. The design of double reinforcing rib rings 5 ​​further enhances the load-bearing capacity of the hub. In addition, the unique structural design of the spoke assembly 4 can effectively increase the contact area between the spoke assembly 4 and the air, allowing the flowing air to dissipate heat from the hub, making the hub less prone to high temperatures and improving the safety of the hub.

[0048] It should be further explained that when spring 124 is in its natural state, the retaining strip 125 is completely submerged inside the connecting groove 123, and the farthest end of the wedge groove 126 away from spring 124 overlaps with the side of the slot 122 closest to spring 124. When spring 212 is in its natural state, the sealing plate 129 blocks the opening of the slot 122. When it is necessary to install the reinforcing rib ring 5 connecting the spoke assembly 4, the straight plate 1210 can be moved away from the axis of the rim 1, thereby causing the sealing plate 129 and the guide rod 1211 to move synchronously and stretch spring 212 until the sealing plate 129 disengages from blocking the opening of the slot 122, but does not disengage from the U-shaped frame 128 adjacent to the straight plate 1210. Then, the wedge-shaped insert 127 is inserted into the slot 122. Inside, the wedge-shaped groove 126 on the clip 125 is pressed, allowing the end of the clip 125 near the groove 121 to be inserted into the groove 121, and the spring 124 is in a stretched state. After the wedge-shaped insert 127 is fully inserted into the slot 122, the force on the straight plate 1210 is removed, and the sealing plate 129 is sealed again by the force of the spring 1212. Conversely, when it is necessary to disassemble the reinforcing rib ring 5 connecting the spoke assembly 4, simply move the straight plate 1210 away from the axis of the rim 1 to release the sealing plate 129 from the opening end of the slot 122. Then, the tensile restoring force of the spring 124 is used to pull the clip 125 back into the connecting groove 123, and the wedge-shaped insert 127 is pushed out of the slot 122 by the wedge-shaped groove 126. The disassembly and assembly are convenient and quick.

[0049] Example 2

[0050] Refer to the instruction manual appendix Figure 2 and Figure 5-7 An embodiment of the present invention provides a metal die-casting part, including a rim 1 and a mounting plate 2 concentrically arranged with the rim 1. The mounting plate 2 has six mounting holes 3 evenly distributed in a ring on its surface. A valve hole 10 is provided on the inner circumferential surface of the rim 1 near the mounting plate 2. Reinforcing rib rings 5 ​​are provided at both ends of the inner circumferential surface of the rim 1. Two snap-fit ​​mechanisms 12 are provided between the reinforcing rib rings 5 ​​and the rim 1, which are axially symmetrical about the axis of the rim 1. A spoke assembly 4 is fixed between the inner circumferential surface of the reinforcing rib ring 5 and the outer circumferential surface of the mounting plate 2.

[0051] The locking mechanism 12 includes a slot 121 formed on the outer circumferential surface of the reinforcing rib ring 5 and a slot 122 formed on the surface of the rim 1. A connecting groove 123, which is cross-shaped and communicates with the slot 122, is formed on the inner circumferential surface of the rim 1 at the position corresponding to the slot 121. A spring 124 is fixedly connected to the inner end face of the connecting groove 123. A locking strip 125 is fixedly connected to the end of the spring 124 facing the slot 121. A wedge-shaped groove 126 is formed through the end of the locking strip 125 away from the slot 121. A wedge-shaped insert 127 is movably inserted into the slot 122. Both sides of the slot 122 on the surface of the rim 1 are fixedly provided with... There is a U-shaped frame 128, and a sealing plate 129 is movably inserted between the two U-shaped frames 128. A straight plate 1210 is fixedly installed at the end of the sealing plate 129 that is off the central axis of the rim 1. A guide rod 1211 is fixedly installed at the middle edge of the side of the straight plate 1210 facing the central axis of the rim 1. The end of the guide rod 1211 away from the straight plate 1210 movably passes through the U-shaped frame 128 that is adjacent to the straight plate 1210. A spring 1212 is movably sleeved on the outer circumference of the guide rod 1211 near the straight plate 1210, and the two ends of the spring 1212 are respectively fixedly connected to the opposite sides of the adjacent U-shaped frame 128 and the straight plate 1210.

[0052] The spoke assembly 4 includes six sets of annularly distributed ring plates 41 and six sets of annularly distributed arc plates 42, with the ring plates 41 and arc plates 42 arranged alternately. The outer circumferential surface of the ring plates 41 is tangent to the inner circumferential surface of the reinforcing rib ring 5 and the outer circumferential surface of the mounting plate 2, and is fixedly connected. Each set of arc plates 42 has two, and the opposite sides of the two arc plates 42 in each set are recessed.

[0053] Furthermore, multiple drainage mesh holes 7 are provided on the surfaces of the two reinforcing rib rings 5 ​​in a through-type manner, which are parallel to the axis of the reinforcing rib rings 5.

[0054] Furthermore, a ring-shaped water guide platform 11 is fixedly provided on the inner circumferential surface of the rim 1. The inner circumferential surface of the water guide platform 11 is configured as a convex arc surface in the direction of the center position of the rim 1. The edge positions of both ends of the water guide platform 11 coincide with the inner edge position of the reinforcing rib ring 5 at the same end.

[0055] It should be noted that, in use, the die-cast wheel hub integrates the rim 1, mounting plate 2, spoke assembly 4, reinforcing rib ring 5, and water guide platform 11 into a single die-cast component. When it rains or a washing truck arrives, the inner circumferential surface of the water guide platform 11 is designed as a convex arc surface oriented towards the center of the rim 1. Furthermore, the surface of the reinforcing rib ring 5 has several drainage holes 7, and the edges of both ends of the water guide platform 11 coincide with the inner edges of the reinforcing rib ring 5 at those ends. This allows water falling inside the rim 1 to converge towards the mesh-like reinforcing rib ring 5 and pass through the drainage holes 7 on the reinforcing rib ring 5. Meanwhile, the spoke assembly 4 is configured as a closed ring structure consisting of alternating ring plates 41 and arc plates 42 connected at the ends. This not only reduces the weight of the spoke assembly 4, but also increases the load strength of the spoke assembly 4 by utilizing the mutual compression and limiting between the ring plates 41 and arc plates 42. Furthermore, the design of double-position reinforcing rib rings 5 ​​greatly improves the load strength of the hub. In addition, the unique structural design of the spoke assembly 4 can effectively increase the contact area between the spoke assembly 4 and the air, allowing the flowing air to dissipate heat from the hub, making the hub less prone to high temperatures and improving the safety of the hub in use.

[0056] It should be further explained that when spring 124 is in its natural state, the retaining strip 125 is completely submerged inside the connecting groove 123, and the farthest end of the wedge groove 126 away from spring 124 overlaps with the side of the slot 122 closest to spring 124. When spring 212 is in its natural state, the sealing plate 129 blocks the opening of the slot 122. When it is necessary to install the reinforcing rib ring 5 connecting the spoke assembly 4, the straight plate 1210 can be moved away from the axis of the rim 1, thereby causing the sealing plate 129 and the guide rod 1211 to move synchronously and stretch spring 212 until the sealing plate 129 disengages from blocking the opening of the slot 122, but does not disengage from the U-shaped frame 128 adjacent to the straight plate 1210. Then, the wedge-shaped insert 127 is inserted into the slot 122. Inside, the wedge-shaped groove 126 on the clip 125 is pressed, allowing the end of the clip 125 near the groove 121 to be inserted into the groove 121, and the spring 124 is in a stretched state. After the wedge-shaped insert 127 is fully inserted into the slot 122, the force on the straight plate 1210 is removed, and the sealing plate 129 is sealed again by the force of the spring 1212. Conversely, when it is necessary to disassemble the reinforcing rib ring 5 connecting the spoke assembly 4, simply move the straight plate 1210 away from the axis of the rim 1 to release the sealing plate 129 from the opening end of the slot 122. Then, the tensile restoring force of the spring 124 is used to pull the clip 125 back into the connecting groove 123, and the wedge-shaped insert 127 is pushed out of the slot 122 by the wedge-shaped groove 126. The disassembly and assembly are convenient and quick.

[0059] It should be noted that, in actual use, the die-cast wheel hub has multiple through-hole ventilation slots 9 on each ring plate 41 and arc plate 42 of the spoke assembly 4. This further increases the contact area between the spoke assembly 4 and the air, allowing the flowing air to quickly dissipate heat from the wheel hub, making it less likely for the wheel hub to have a high temperature and improving the safety of wheel hub use.

[0060] Example 4

[0061] Refer to the instruction manual appendix Figure 4 and Figure 9 According to one embodiment of the present invention, a metal die-casting part is different from that in embodiment 2, in that the surfaces of the ring plate 41 and the arc plate 42 are provided with multiple through-hole ventilation slots 9.

[0062] It should be noted that, in actual use, the die-cast wheel hub has multiple through-hole ventilation slots 9 on each ring plate 41 and arc plate 42 of the spoke assembly 4. This further increases the contact area between the spoke assembly 4 and the air, allowing the flowing air to quickly dissipate heat from the wheel hub, making it less likely for the wheel hub to have a high temperature and improving the safety of wheel hub use.
