Description

Technical Field

[0001] This utility model relates to the field of wheel hub casting molds, and in particular to a wheel hub casting side mold with a water-cooled insert. Background Technology

[0002] As a key component of automobiles, wheels not only bear the important task of supporting the tires and connecting the suspension system, but their appearance and performance also have a profound impact on the overall performance of the vehicle. With consumers' growing demand for personalized and high-performance vehicles, wheel design and manufacturing technologies have become particularly important.

[0003] Low-pressure casting is a commonly used process in wheel manufacturing. Mold temperature plays a crucial role in this process, directly affecting the solidification of the molten alloy and thus determining the internal structure, surface quality, and dimensional accuracy of the casting. Inappropriate mold temperature can lead to defects such as dimensional deviations and deformation in the casting, severely impacting product quality and production efficiency. Especially when forging large-size aluminum alloy wheel castings, the cooling process during die casting is unique and complex due to the large difference in wall thickness and complex shape of the tire ring.

[0004] Currently, patent CN210996338U proposes a wheel hub casting side mold that improves heat dissipation in the thicker rim area above the front wheel flange by setting wind claws on the side mold. However, this design still has many problems in practical applications. First, because the wind claws are close to the front wheel flange, the wheel hub thickness in this area is relatively large, making heat dissipation difficult and resulting in a loose structure after molding, failing to meet process requirements. Second, although air ducts are set for air cooling, the heat dissipation effect is limited, the casting cycle is long, and the production capacity is low. In addition, although the integral insert (water cooling) has a better heat dissipation effect, the manufacturing cost is high, the processing cycle is long, and the casting process is unstable. During the cooling process, there is also a risk of water source blockage, resulting in poor cooling effect, further affecting product quality and production efficiency.

[0005] Therefore, there is an urgent need to modify and optimize the existing wheel hub side molds to address the problems of poor cooling effect, long casting cycle, low production capacity and poor product quality during the casting process. Utility Model Content

[0006] Therefore, it is necessary to provide a wheel hub casting side mold with a water-cooled insert to address the above-mentioned technical problems.

[0007] A wheel hub casting side mold with water-cooled inserts includes: a side mold assembly and several water-cooled inserts;

[0008] The side mold assembly includes multiple mounting blocks, which are arranged in a ring shape.

One end of the circulating cold water channel is connected to the water inlet, and the other end of the circulating cold water channel is connected to the water outlet.

[0011] In one embodiment, a first connection port is provided on one side of the outer surface of the water-cooled insert, and a second connection port is provided on the other side of the outer surface of the water-cooled insert.

[0018] In one embodiment, the number of mounting blocks is 4, and the mounting blocks are arranged in a ring.

[0019] In one embodiment, a positioning pin that matches the positioning hole is inserted into the positioning hole to fix the water-cooled insert.

[0020] This utility model presents a wheel hub casting side mold with water-cooled inserts, which improves upon the traditional air-cooling cooling of side molds by replacing it with water-cooling cooling.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Example

[0027] In this embodiment, as Figures 1 to 2 As shown, a wheel hub casting side mold with water-cooled inserts is provided, including: a side mold assembly 10 and a plurality of water-cooled inserts 20;

[0028] like Figure 2 As shown, the side mold assembly 10 includes a plurality of mounting blocks 30, which are arranged in a ring shape;

[0029] Each of the mounting blocks 30 has a positioning hole 110 inside. The water-cooled insert 20 is nested on the mounting block 30 through the positioning hole 110. The inner side of the water-cooled insert 20 abuts against the outer surface of the wheel hub to be cast.

[0030] Each of the water-cooled inserts 20 has a circulating cold water channel 120 inside. One end face of the water-cooled insert 20 is provided with a water inlet 210, and the side away from the water inlet 210 is provided with a water outlet 310. One end of the circulating cold water channel 120 is connected to the water inlet 210, and the other end of the circulating cold water channel 120 is connected to the water outlet 310.

[0031] Specifically, the side mold assembly 10 and several water-cooled inserts 20 are included. The side mold assembly 10 consists of multiple mounting blocks 30, which are arranged in a ring shape to form part of the mold and are used to form the side features of the wheel hub. Each mounting block 30 has a positioning hole 110 inside, through which the water-cooled inserts 20 are nested onto the mounting block 30, ensuring that the water-cooled inserts 20 can be accurately installed in a predetermined position and that their inner surfaces are tightly fitted to the outer surface of the wheel hub for forming specific areas of the wheel hub. Each water-cooled insert 20 has a circulating cooling water channel 120 inside. Cooling water enters through the inlet 210 on one end face of the insert, carries away heat through the circulating cooling water channel 120 inside the insert, and flows out from the outlet 310 on the side away from the inlet 210, forming a complete cooling circulation path.

[0032] The wheel hub casting side mold with water-cooled inserts 20 in the above embodiment improves the traditional air-cooling cooling of the side mold to water-cooling cooling. The water-cooled inserts 20 are nested into the side mold through positioning holes 110, providing water cooling for the thicker rim area of ​​the wheel hub. Each water-cooled insert 20 is equipped with a circulating cooling water channel 120, an inlet 210, and an outlet 310. This design reduces pressure loss over long pipelines, allowing for smoother flow of cooling water within each side mold and improving cooling efficiency. This helps reduce thermal stress and prevents product deformation during cooling, thereby enhancing cooling effect, shortening the molding cycle, and improving product quality and production efficiency.

[0033] In one embodiment, such as Figures 2 to 3 As shown, a first connection port 410 is provided on one side of the outer surface of the water-cooled insert 20, and a second connection port 510 is provided on the other side of the outer surface of the water-cooled insert 20.

[0034] In the above embodiments, in order to make the circulating cold water channels 120 in each water-cooled insert 20 interconnected, a first connection port 410 is provided on one side of the outer surface of the water-cooled insert 20, and a second connection port 510 is provided on the other side of the outer surface of the water-cooled insert 20.

[0035] In one embodiment, such as Figure 2 As shown, one end of the first connection port 410 is connected to the circulating cold water channel 120, and the other end of the first connection port 410 is connected to the circulating cold water channel 120 of another water-cooled insert 20. The circulating cold water channels 120 of two adjacent water-cooled inserts 20 are connected.

[0036] In the above embodiments, to ensure that the circulating cooling water channels 120 within each water-cooled insert 20 are interconnected and that the cooling effect is uniform, one end of the first connection port 410 on each water-cooled insert 20 is connected to the circulating cooling water channel 120 inside the insert, and the other end of the first connection port 410 is connected to the circulating cooling water channel 120 of the adjacent water-cooled insert 20. The first connection port 410 of each water-cooled insert 20 is not only connected to its own internal circulating cooling water channel 120, but also to the circulating cooling water channel 120 of the adjacent insert, forming a continuous cooling system. This connection method ensures the uniform distribution of cooling water throughout the mold, improves cooling efficiency, thereby enhancing product quality and production efficiency. Simultaneously, it cools the connection point between two adjacent mounting blocks 30, preventing localized overheating that could cause product deformation.

[0037] In one embodiment, such as Figure 2 As shown, one end of the second connection port 510 is connected to the circulating cold water channel 120, and the other end of the second connection port 510 is connected to the circulating cold water channel 120 of another water-cooled insert 20. The circulating cold water channels 120 of two adjacent water-cooled inserts 20 are connected.

[0038] In the above embodiments, to ensure that the circulating cooling water channels 120 within each water-cooled insert 20 are interconnected and that the cooling effect is uniform, one end of the second connection port 510 on each water-cooled insert 20 is connected to the circulating cooling water channel 120 inside that insert, and the other end of the second connection port 510 is connected to the circulating cooling water channel 120 of the adjacent water-cooled insert 20. The second connection port 510 of each water-cooled insert 20 is not only connected to its own internal circulating cooling water channel 120, but also to the circulating cooling water channel 120 of the adjacent insert, forming a continuous cooling system. This connection method ensures the uniform distribution of cooling water throughout the mold, improves cooling efficiency, thereby enhancing product quality and production efficiency. Simultaneously, it cools the connection point between two adjacent mounting blocks 30, preventing localized overheating that could cause product deformation.

[0039] In one embodiment, the positioning hole 110 corresponds to the rim position of the wheel hub to be cast.

[0040] To reduce heat conduction between the interior and exterior environments of the water-cooled insert 20, in one embodiment, such as... Figure 3 As shown, the water-cooled insert 20 has multiple heat-insulating grooves 610 on the side near the circulating cooling water channel 120, and the heat-insulating grooves 610 are annular grooves. In this embodiment, the annular heat-insulating grooves 610 can reduce heat conduction between the interior of the insert and the external environment. Since the cooling water flows within the circulating cooling water channel 120, the presence of the heat-insulating grooves 610 can reduce heat conduction from the cooling water channel to other parts of the insert, thereby improving cooling efficiency.

[0041] In another embodiment, such as Figure 4 As shown, the mounting block 30 is provided with a temperature measuring hole 511.

[0042] To effectively reduce cooling water flow rate, increase flow rate, reduce pressure loss, and improve connection stability, thereby minimizing connection problems caused by pipe vibration or external pressure fluctuations, in one embodiment, such as... Figure 3 As shown, an external pipe 810 is provided on the outer extension of the water inlet 210, and the width of the external pipe 810 is greater than the width of the circulating cold water channel 120. In this embodiment, the width of the external pipe 810 is greater than the width of the circulating cold water channel 120, which can reduce the flow velocity of the cooling water when it enters the water-cooled insert 20. Reducing the flow velocity can reduce the impact force of the water flow on the inside of the water-cooled insert 20, thereby reducing hydraulic loss and noise, and improving the stability of the connection.

[0043] In one embodiment, please combine Figure 1 and Figure 2 As shown, there are four mounting blocks 30 arranged in a ring. Each mounting block 30 is an independent module, facilitating individual manufacturing, maintenance, and replacement. If a mounting block 30 is damaged or worn, it can be replaced individually without replacing the entire mold. Each mounting block 30 also has an independent water-cooling insert 20, allowing for independent adjustment of the cooling effect to ensure optimal cooling for all parts of the mold.

[0044] In one embodiment, such as Figure 4 As shown, the system also includes a positioning pin 910 that matches the positioning hole 110. The positioning pin 910 is inserted into the positioning hole 110 to fix the water-cooled insert 20. The insertion of the positioning pin 910 into the positioning hole 110 ensures that the water-cooled insert 20 can be accurately installed in the predetermined position. This can prevent the insert from shifting or loosening during use, thereby ensuring the accuracy and stability of the mold.

[0045] In one embodiment, a welded seal (not shown) is also included. When the circulating cold water channel extends inside the water-cooled insert, the welded seal is used at the connection of the cold water channel to prevent coolant from leaking and damaging the mold. At the same time, when the water channel is not connected to another water channel, a small section of the outer end of the water channel is sealed by a weld at the welded seal end to prevent liquid leakage, leaving only interconnected water channels to form a circulating cold water channel for cooling.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
