Description

Technical Field

[0001] This utility model relates to the field of wheel hub casting equipment, and in particular to a wheel hub casting machine. Background Technology

[0002] A wheel hub is a cylindrical metal component inside a car tire, centered on an axle, used to support the tire. Simply put, it's the part in the center of the wheel where the axle is mounted. It's an important component connecting the brake drum (brake disc), wheel disc, and half-shaft. Wheel hubs are usually cast using a wheel hub casting machine. The manufacturing process involves pouring liquid aluminum alloy into a casting mold, allowing the liquid aluminum alloy to solidify into a solid wheel hub blank, removing the wheel hub blank, cooling it, and then performing finishing processes such as deburring and polishing to finally obtain the finished product.

[0003] Existing wheel hub casting machine structures, such as the aluminum alloy wheel hub casting device disclosed in Chinese patent application number CN202221822697.7, specifically disclose a fixed frame, a lower mold sleeve, an upper mold, and a stop seat. A box is installed on one side of the fixed frame, and the upper mold is connected to the fixed frame via a lifting component. The stop seat is slidably sealed inside the lower mold sleeve, and an ejection component is provided at the bottom of the stop seat. The lower mold sleeve is located in the middle of the inner side of the box via a connecting component. A U-shaped tube is connected to the inner side of the box via a conveying mechanism. The U-shaped tube is located above the outer side of the lower mold sleeve, and straight pipes extend to one side from both ends of the U-shaped tube. Multiple sets of spray pipes are connected and installed inside the straight pipes, with the spray direction of the multiple sets of spray pipes all located at the lower mold sleeve. A storage box is installed inside the fixed frame, and a pushing component is provided inside the storage box. A guiding component is installed on the outer wall of one side of the box.

[0004] The aforementioned aluminum alloy wheel hub casting device forms a casting mold by closing the upper and lower molds, and then pouring liquid aluminum alloy into the casting mold to form the wheel hub. However, the structure of the wheel hub is relatively complex, and casting defects such as incomplete filling, shrinkage cavities, cold shuts, hot cracks and shrinkage cracks occur during the casting process, resulting in unqualified cast wheel hubs. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model provides a wheel hub casting machine, which mainly solves the problem of poor wheel hub quality produced by existing wheel hub casting machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Furthermore, the cooling assembly includes a fan, a duct, and an air outlet shroud. The air outlet shroud has an air inlet and an air outlet. The cross-sectional area of ​​the air outlet of the air outlet shroud is larger than that of the air inlet. The air outlets of the air outlet shroud are distributed on the lower side of the guide assembly. The fan is connected to the air inlet of the air outlet shroud through the duct.

[0009] Furthermore, the demolding assembly includes a receiving rack, a second linear drive assembly, a third linear drive assembly, a guide rod, a sliding sleeve, a crank, a movable seat, and a receiving tray.

[0013] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: When using this wheel hub casting machine, the upper and lower lifting components drive the upper and lower mold plates to rise and fall respectively, so that the upper and lower molds close and the liquid alloy is poured into the mold cavity. Then, the first linear drive component drives the support to swing. The swing of the support can cause the upper and lower molds to swing and shake at a certain angle, which helps the liquid aluminum alloy to flow and fill better in the mold, effectively reducing casting defects such as incomplete filling, shrinkage cavities, cold shuts, hot cracks and shrinkage cracks, and improving the quality of the cast wheel hub. The guide component ensures the precise sliding of the upper mold plate and the upper mold. At the same time, the cooling component cools the mold. After cooling and forming, the mold is opened, and the formed wheel hub is received by the demolding component, which facilitates demolding. The overall structure improves the efficiency and yield of wheel hub casting. Attached Figure Description

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] The embodiment of this utility model is as follows:

[0021] refer to Figures 1 to 5As shown, a wheel hub casting machine includes a base 1, two support seats 2, a rotating shaft 3, a bracket 4, a first linear drive assembly 5, an upper lifting assembly 6, a lower lifting assembly 7, an upper template 8, a lower template 9, an upper mold (not shown), a lower mold (not shown), a guide assembly 10, a cooling assembly 11, and a demolding assembly 12. The length direction of the base 1 is defined as the transverse direction, the width direction as the longitudinal direction, and the height direction as the vertical direction. The two support seats 2 are respectively located on the longitudinal sides of the base 1. The rotating shaft 3 is rotatably mounted on the two support seats 2. The bracket 4 is mounted on the rotating shaft 3 and distributed between the two support seats 2. The first linear drive assembly 5, an upper lifting assembly 6, a lower lifting assembly 7, an upper template 8, a lower template 9, an upper mold (not shown), a lower mold (not shown), a guide assembly 10, a cooling assembly 11, and a demolding assembly 12. The two ends of the linear drive assembly 5 are connected to the base 1 and the bracket 4 respectively. The bracket 4 is driven to swing by the first linear drive assembly 5. The guide assembly 12 is located in the middle of the bracket 4 and is distributed in the vertical direction. The upper lifting assembly 6 is located in the upper part of the bracket 4. The upper template 8 is located in the lower end of the upper lifting assembly 6 and slides along the guide assembly 10. The upper mold is located on the lower surface of the upper template 8. The lower lifting assembly 7 is located in the lower part of the bracket 4. The lower template 9 is located in the upper end of the lower lifting assembly 7. The lower mold is located on the upper surface of the lower template 9. The cooling assembly 11 is located on the bracket 4 and is used for cooling the upper mold and the lower mold. The demolding assembly 12 is located on the base 1 and is distributed around the lower mold.

[0022] In operation, this wheel casting machine uses the upper lifting assembly 6 and the lower lifting assembly 7 to drive the upper mold plate 8 and the lower mold plate 9 to rise and fall, respectively, so that the upper and lower molds close and the liquid alloy is poured into the mold cavity. Then, the first linear drive assembly 5 drives the support 4 to swing. The swing of the support 4 can cause the upper and lower molds to swing and shake at a certain angle, which helps the liquid aluminum alloy to flow and fill better in the mold, effectively reducing casting defects such as incomplete filling, shrinkage cavities, cold shuts, hot cracks and shrinkage cracks, and improving the quality of the cast wheel. The guide assembly ensures the precise sliding of the upper mold plate 8 and the upper mold. At the same time, the cooling assembly 11 cools the mold. After cooling and forming, the mold is opened, and the formed wheel is received by the demolding assembly 12 for easy demolding. The overall structure improves the efficiency and yield of wheel casting.

[0023] Furthermore, the cooling assembly 11 includes a fan 111, an air duct 112, and an air outlet shroud 113. The air outlet shroud 113 has an air inlet 101 and an air outlet 102. The cross-sectional area of ​​the air outlet 102 of the air outlet shroud 113 is larger than that of the air inlet 101. The air outlet 102 of the air outlet shroud 113 is located on the lower side of the guide assembly 10. The fan 111 is connected to the air inlet 101 of the air outlet shroud 113 through the air duct 112. The cross-sectional area of ​​the air outlet 102 of the air outlet shroud 113 is larger than that of the air inlet 101. This design allows the air to diffuse at the air outlet shroud 113, expanding the cooling range. Moreover, the air outlet 102 is located on the lower side of the guide assembly 10, which can more effectively cool the upper and lower molds, accelerate the mold cooling speed, shorten the casting cycle, improve production efficiency, and at the same time help improve the casting quality of the wheel hub.

[0024] Meanwhile, the demolding assembly 12 includes a receiving rack 121, a second linear drive assembly 122, a third linear drive assembly 123, a guide rod 124, a sliding sleeve 125, a crank 126, a movable seat 127, and a receiving tray 128. The receiving rack 121 is mounted on the base 1. The guide rod 124 is rotatably mounted on the receiving rack 121 and distributed vertically. The crank 126 is located at the lower end of the guide rod 124. The two ends of the second linear drive assembly 122 are connected to the base 1 and the crank 126, respectively. The second linear drive assembly 122 drives the guide rod 124 to rotate. The sliding sleeve 125 slidably mounts the guide rod. The third linear drive assembly 123, mounted on the guide rod 124, is connected at both ends to the sliding sleeve 125 and the receiving rack 121, respectively. The receiving tray 128 is connected to the sliding sleeve 125 via the movable seat 127. The guide rod 124 is rotated by the second linear drive assembly 122, and the sliding sleeve 125 is slid on the guide rod 124 by the third linear drive assembly 123. This allows the receiving tray 128 to move flexibly and adjust its position in multiple directions, accurately catching the cast wheel hubs and preventing them from falling and being damaged after demolding. This improves the integrity of the product and the safety of production, while also facilitating the subsequent collection and processing of the wheel hubs.

[0025] Furthermore, the movable seat 127 includes a fixed part 201 fixed to the sliding sleeve 125, a support rod 202 rotatably disposed on the fixed part 201, and a drive motor 203 connected to the support rod 202. The support rod 202 is distributed in a horizontal direction, and the receiving tray 128 is disposed on the support rod 202, so that the receiving tray 128 can rotate and adjust around the central axis of the support rod 202. This further increases the positional flexibility of the receiving tray 128, which can better adapt to the wheel hubs demolded in different positions, ensure accurate material receiving, improve the accuracy and reliability of material receiving, reduce wheel hub damage caused by inaccurate material receiving, and facilitate wheel hub transfer, thereby improving ease of use.

[0026] In this embodiment, the first linear drive component 5, the second linear drive component 122, the third linear drive component 123, the upper lifting component 6, and the lower lifting component 7 are all hydraulic cylinders, pneumatic cylinders, or electric cylinders, preferably hydraulic cylinders. This type of drive has the characteristics of strong power, stable operation, and high control precision. It can accurately control the movement stroke and speed of each component, ensuring the stability and reliability of the entire wheel hub casting machine during operation, thereby improving the quality and production efficiency of wheel hub casting.

[0027] In this embodiment, the base 1 is provided with a first limiting member 13 and a second limiting member 14 to limit the swing angle of the bracket 4. This can limit the swing angle of the bracket 4, prevent the bracket 4 from swinging too much and affecting the normal mold closing and casting process, ensure that the bracket 4 swings within a reasonable angle range, ensure the stability and accuracy of the wheel hub casting, avoid casting defects caused by abnormal bracket swing, and improve product quality.
