Description

Technical Field

[0001] This utility model relates to the field of wheel hub casting technology, 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 device including a fixed frame, a lower mold sleeve, an upper mold, and a stop. A box is installed on one side of the fixed frame, and the upper mold is connected to the fixed frame via a lifting assembly. The stop is slidably sealed to the inner side of the lower mold sleeve, and an ejection assembly is provided at the bottom of the stop. The lower mold sleeve is located in the middle of the inner side of the box via a connecting assembly. 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 material pushing assembly is provided inside the storage box. A material guiding assembly 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.

The length direction of the base 1 is defined as the transverse direction, and the width direction of the base 1 is defined as the longitudinal 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 two ends of the first linear drive assembly 5 are respectively connected to the base 1 and the bracket 4, driving the bracket 4 to swing. The bracket 4 has a casting station 40. Each of the side mold assembly 9 is mounted on the bracket 4 and evenly distributed around the casting station 40. The lower mold assembly... Component 11 is located on the lower side of casting station 40. The first guide component 7 is located on the upper side of casting station 40 of support 4 and is distributed in the lateral direction. The movable seat 8 is located on the first guide component 7. The second linear drive component 6 is connected to the movable seat 8 and is used to drive the movable seat 8 to move along the guide direction of the first guide component 7. The upper mold closing component 10 is located on the movable seat 8 and drives the mold closing and opening of the casting mold through the side mold closing component 9, the upper mold closing component 10 and the lower mold closing component 11. The material receiving component 12 is located on support 4 and is located on the periphery of casting station 40. In this embodiment, the structure of the casting mold consists of an upper mold, a lower mold, a side mold assembly and a standard mold frame. The side mold assembly is a 4-open side mold assembly, that is, a side mold assembly composed of 4 side molds. Each side mold is an integral structure and is installed on the side mold closing component 9. The upper mold and the lower mold are installed on the upper mold closing component 10 and the lower mold closing component 11, respectively.

[0020] In use, this wheel hub machine drives the various parts of the casting mold to close through the side mold assembly 9, upper mold assembly 10, and lower mold assembly 11, and pours liquid alloy into the casting mold. Then, the first linear drive assembly 5 drives the bracket 4 to swing, thereby causing the casting mold to swing, so that the liquid alloy fills the mold cavity in the casting mold, avoiding casting defects such as shrinkage cavities, cold shuts, hot cracks, and shrinkage cracks, thereby improving the quality of the cast wheel hub. After cooling and forming, the mold is opened, and the second linear drive assembly 6 drives the upper mold opening assembly 10 to move along the guide direction of the first guide assembly 7 to the receiving assembly 12, transferring the cast wheel hub to the receiving assembly 12, improving the convenience of use and thus improving production efficiency.

[0021] Furthermore, the receiving assembly 12 includes a fixed base 121, a third linear drive assembly 122, a second guide assembly 123, and a receiving tray 124. The fixed base 121 is mounted on the bracket 4, the second guide assembly 123 is mounted on the fixed base 121, and the receiving tray 124 is mounted on the second guide assembly 123 and distributed on the upper side of one of the side mold assembly 9. The third linear drive assembly 122 is connected to the receiving tray 124 and is used to drive the receiving tray 124 to move along the guide direction of the second guide assembly 123, so that the receiving tray 124 can move accurately and smoothly to a suitable position, which facilitates the receiving of the cast wheel hub and avoids damage to the wheel hub due to collisions during the receiving process, thereby further improving the quality and efficiency of wheel hub production.

[0022] In this embodiment, there are four side mold assembly 9, which can apply pressure to the casting mold more evenly and stably from multiple directions, so that the casting mold is subjected to more balanced force during the mold closing process, effectively preventing problems such as mold deformation or uneven wheel hub forming caused by uneven force, thereby further improving the quality and precision of wheel hub casting; of course, it can also be set to three, five or even more.

[0023] Furthermore, the side-clamping mold assembly 9 includes a first mounting base 91, a front connecting base 92, a rear connecting base 93, a fourth linear drive assembly 94, multiple guide rods 95, and multiple guide sleeves 96. The first mounting base 91 is mounted on the bracket 4, each guide sleeve 96 is circumferentially mounted on the first mounting base 91, and each guide rod 95 passes through each guide sleeve 96. The rear connecting base 93 is located on one end of each guide rod 95 away from the casting station 40. The two ends of the fourth linear drive assembly 94 are connected to the first mounting base 91 and the rear connecting base 93. The front connecting seat 92 is located on each guide rod 95 at one end near the casting station 40. The first mounting seat 91 is fixed on the bracket 4 to provide support for the whole. The guide sleeve 96 and the guide rod 95 cooperate to guide the movement and ensure the linearity of the movement of the front connecting seat 92 and the rear connecting seat 93. The fourth linear drive assembly 94 provides power to drive the rear connecting seat 93 to move, thereby driving the front connecting seat 92 to achieve the mold closing action. This structure makes the movement of the side mold closing assembly 9 more precise and stable, which is conducive to improving the mold closing quality and reducing wheel hub casting defects caused by inaccurate mold closing.

[0024] Meanwhile, the first linear drive assembly 5, the second linear drive assembly 6, the third linear drive assembly 122 and the fourth linear drive assembly 94 are all hydraulic cylinders, pneumatic cylinders or electric cylinders, preferably hydraulic cylinders. The drive method has the characteristics of stable power output and high control precision, which can more accurately control the movement speed and displacement of each component, thereby better realizing actions such as mold closing, mold opening and material receiving, which helps to improve the overall working stability of the wheel hub machine and the wheel hub casting quality.

[0025] In this embodiment, a limiting member 13 is provided on the lateral side of the base 1 to limit the swing angle of the bracket 4. This can accurately control the swing range of the bracket 4, prevent the swing angle of the bracket 4 from being too large or too small, thus affecting the accuracy of operations such as mold closing and mold opening, ensuring that each component moves within a suitable spatial range, improving the stability and reliability of the wheel hub machine, and thus ensuring the quality of wheel hub casting.
