Description

Technical Field

[0001] This utility model relates to the field of wheel hub mold equipment technology, and in particular to a wheel hub mold with a cooling function. Background Technology

[0002] The car wheel is an important component of the car. The wheel hub is a cylindrical metal part inside the car tire that supports the tire with the axle as the center. It is the part where the axle is installed in the center of the wheel and is an important component connecting the brake disc, wheel disc and half shaft. In the production and manufacturing process of wheel hubs, the mold is a crucial tool. The performance of the wheel hub mold affects the quality of the wheel hub and the production efficiency.

[0003] Existing wheel hub mold cooling systems are relatively simple, often employing a single cooling channel structure. For example, cooling channels are only set in certain areas of the mold along the circumferential and axial directions. However, due to differences in wheel hub size, structure, and manufacturing processes, the requirements for cooling speed and cooling area vary. Traditional molds cannot flexibly adjust the effective cooling length of the cooling channels according to actual needs, resulting in uneven cooling effects. This leads to inconsistent cooling speeds in different parts of the wheel hub, which can easily cause internal stress during the molding process, thereby affecting the quality of the wheel hub and causing defects such as deformation and cracks. Utility Model Content

[0004] This invention addresses the problem that traditional molds cannot adjust the effective cooling length of the cooling channels according to the cooling requirements of the wheel hub, resulting in inconsistent cooling speeds in different parts, which can easily lead to defects such as wheel hub deformation and cracks, thus affecting the quality of the wheel hub. The invention proposes a wheel hub mold with a cooling function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a wheel hub mold with a cooling function, including an upper mold body, a lower mold body, and a side mold body. The upper mold body, lower mold body, and side mold body enclose the forming space of the wheel hub. The side mold body is provided with a first cooling water channel and a second cooling water channel. The first cooling water channel is arranged circumferentially along the side mold body and has an inlet and an outlet. One end of the second cooling water channel is connected to the first cooling water channel and is located between the inlet and the outlet. The second cooling water channel extends axially along the side mold body. The other end of the second cooling water channel is connected to a water channel adjustment mechanism. The water channel adjustment mechanism is provided with a telescopic plug, which is movably connected inside the second cooling water channel and can telescopically move to adjust the effective cooling length of the second cooling water channel.

[0007] Furthermore, the water channel adjustment mechanism is equipped with a drive electric cylinder, and the telescopic plugging component includes a connecting rod and a plugging head. The drive electric cylinder is connected to the side mold body. One end of the connecting rod is fixedly connected to the movable end of the drive electric cylinder, and the other end is fixedly connected to the plugging head. The plugging head is movably and sealingly connected to the second cooling water channel. The drive electric cylinder is at least used to drive the connecting rod to move axially along the side mold body, so as to drive the plugging head to move along the second cooling water channel.

[0008] Furthermore, the water channel adjustment mechanism includes a mounting bracket, which is fixed on the side mold body. A drive electric cylinder is connected to the mounting bracket, and there is a receiving space along the axial direction of the side mold body between the mounting bracket and the side mold body. When the drive electric cylinder is in the retracted state, the connecting rod and the plug head move to the receiving space to open the second cooling water channel.

[0009] Furthermore, the sidewall of the plug head is provided with a sealing groove arranged along its own circumference, and an annular sealing gasket is connected inside the sealing groove. The annular sealing gasket fills the space between the sidewall of the sealing groove and the second cooling water channel.

[0010] Furthermore, an elastic sealing gasket is provided at one end of the plug head relative to the connecting rod.

[0011] Furthermore, it also includes multiple second cooling channels, which are evenly spaced along the circumference of the side mold body, and are all located between the inlet and outlet.

[0012] Furthermore, the end face of the side mold body away from the first cooling water channel is provided with an overflow groove, which is connected to the opening of the second cooling water channel at the end opposite to the first cooling water channel.

[0013] Furthermore, the side mold body includes at least four side modules, which are combined to form the side mold body. Each side module includes a first cooling water channel, a second cooling water channel, and a water channel adjustment mechanism.

[0014] Furthermore, it also includes a control module, a temperature monitoring module, and a flow control valve. The flow control valve is connected to the water inlet. The temperature monitoring module is connected to the side mold body located on one side of the molding space. Both the temperature monitoring module and the flow control valve are connected to the control module. The control module is connected to the water channel adjustment mechanism. The temperature monitoring module is used to monitor the temperature of the wheel hub and transmit the temperature signal to the control module. The control module receives the temperature signal and controls the water channel adjustment mechanism to drive the telescopic plug to move. The control module controls the flow control valve to adjust the flow rate of the water inlet.

[0015] Furthermore, the upper mold inner plate is provided with a first cooling pipe, and the lower mold inner plate is provided with a second cooling pipe.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are:

[0017] This invention cools the wheel hub from multiple directions by setting up a first cooling water channel and a second cooling water channel, effectively avoiding the problem of uneven cooling caused by a single cooling water channel. At the same time, by setting a telescopic plug on the second cooling water channel, the effective cooling length of the second cooling water channel can be flexibly and precisely adjusted according to the actual production needs of the wheel hub by extending and retracting the telescopic plug, which improves the versatility of the mold and production efficiency. Uniform cooling ensures that the cooling speed of all parts of the wheel hub is consistent, reducing the internal stress during the wheel hub forming process and improving the quality of the wheel hub.

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] Please see Figures 1-5 A wheel hub mold with cooling function includes an upper mold body 100, a lower mold body 200, and a side mold body 300. The upper mold body 100, lower mold body 200, and side mold body 300 enclose a forming space 310 for the wheel hub. The side mold body 300 is provided with a first cooling water channel 320 and a second cooling water channel 330. The first cooling water channel 320 is arranged circumferentially along the side mold body 300 and has an inlet 321 and an outlet 322. One end of the second cooling water channel 330 is connected to... The first cooling water channel 320 is connected and located between the inlet 321 and the outlet 322. The second cooling water channel 330 extends along the axial direction of the side mold body 300. The other end of the second cooling water channel 330 is connected to a water channel adjustment mechanism 400. The water channel adjustment mechanism 400 is provided with a telescopic plug 410. The telescopic plug 410 is movably connected in the second cooling water channel 330 and can telescopically move to adjust the effective cooling length of the second cooling water channel 330.

[0028] In this embodiment, as Figure 1 , Figure 3As shown, the side mold body 300 can be a hollow annular structure. The upper mold body 100 is installed on the upper end of the side mold body 300, and the lower mold body 200 is installed on the lower end of the side mold body 300. Thus, the upper mold body 100, the side mold body 300, and the lower mold body 200 together enclose the forming space 310 of the wheel hub. In use, casting material is injected into the forming space 310, and the casting material is formed into a wheel hub structure within the forming space 310. A first cooling water channel 320 is provided at the bottom end of the side mold body 300. This first cooling water channel 320 is arranged horizontally and distributed circumferentially along the side mold body 300. One end of the first cooling water channel 320 opens to form an inlet 321, and the other end opens to form an outlet 322. Additionally, in... The side mold body 300 is also provided with a vertical second cooling water channel 330, which is located between the inlet 321 and the outlet 322. The lower opening of the second cooling water channel 330 is connected to the first cooling water channel 320, and the upper opening of the second cooling water channel 330 is connected to the water channel adjustment mechanism 400. The water channel adjustment mechanism 400 includes a telescopic blocking member 410, which can close the upper opening of the second cooling water channel 330 and can move vertically within the second cooling water channel 330, thereby adjusting the effective cooling length of the second cooling water channel 330. Thus, after the cooling water is injected, the water level in the second cooling water channel 330 can be adjusted.

[0029] In actual operation, liquid metal is injected into the wheel hub forming space 310, which is enclosed by the upper mold body 100, the lower mold body 200, and the side mold body 300. The cooling system then begins to operate. Coolant flows in from the inlet 321 of the first cooling channel 320, flows within the circumferentially surrounding first cooling channel 320, carrying away heat from the circumference of the side mold body 300, and then flows out from the outlet 322. Simultaneously, some coolant enters the second cooling channel 330 and flows axially to cool the side mold body 300. During the cooling process, if the temperature in a certain area of ​​the wheel hub is too high, the telescopic plug 410 contracts and moves upward in the vertical direction, thereby increasing the effective cooling length of the second cooling channel 330 and enhancing the cooling effect in that area. If the temperature in a certain area of ​​the wheel hub is too low, the telescopic plug 410 extends and moves downward in the vertical direction, thereby reducing the effective cooling length of the second cooling channel 330 and preventing overcooling.

[0030] In the above structure, by setting the first cooling water channel 320 and the second cooling water channel 330, the wheel hub is cooled from multiple directions, effectively avoiding the problem of uneven cooling caused by a single cooling water channel. At the same time, by setting the telescopic plug 410 on the second cooling water channel 330, the effective cooling length of the second cooling water channel 330 can be flexibly and precisely adjusted according to the actual production needs of the wheel hub by telescopically moving the plug 410. By controlling the position of the plug head 412, the cooling area and cooling speed can be precisely controlled, which greatly improves the versatility of the mold and the production efficiency. Meanwhile, uniform cooling makes the cooling speed of all parts of the wheel hub consistent, greatly reducing the internal stress during the wheel hub forming process, significantly reducing the probability of defects such as deformation and cracks in the wheel hub, and improving the quality of the wheel hub.

[0031] In the specific structure of the water channel regulating mechanism 400, the water channel regulating mechanism 400 is provided with a drive electric cylinder 420, and the telescopic blocking member 410 includes a connecting rod 411 and a blocking head 412. The drive electric cylinder 420 is connected to the side mold body 300. One end of the connecting rod 411 is fixedly connected to the movable end of the drive electric cylinder 420, and the other end is fixedly connected to the blocking head 412. The blocking head 412 is movably and sealingly connected to the second cooling water channel 330. The drive electric cylinder 420 is at least used to drive the connecting rod 411 to move axially along the side mold body 300, so as to drive the blocking head 412 to move along the second cooling water channel 330.

[0032] In this embodiment, as Figure 1 As shown, the drive cylinder 420 is fixed vertically to the upper end face of the side mold body 300. The connecting rod 411 extends vertically, and its upper end is fixedly connected to the movable end of the drive cylinder 420. The lower end of the connecting rod 411 is fixedly connected to the plug head 412. The shape of the plug head 412 is adapted to the inner diameter of the second cooling water channel 330 to achieve a movable and sealed connection with the second cooling water channel 330. The drive cylinder 420 can drive the connecting rod 411 to move vertically, thereby driving the plug head 412 to move within the second cooling water channel 330, thus adjusting the effective cooling length of the second cooling water channel 330. By precisely controlling the position of the plug head 412 within the second cooling water channel 330 through the drive cylinder 420, the effective cooling length of the second cooling water channel 330 can be precisely adjusted according to the real-time temperature changes of different parts of the wheel hub.

[0033] The plug head 412 has a sealing groove 4121 arranged circumferentially on its side wall. An annular sealing gasket 440 is connected inside the sealing groove 4121 and fills the space between the sealing groove 4121 and the side wall of the second cooling water channel 330. An elastic sealing gasket 450 is provided at one end of the plug head 412 opposite to the connecting rod 411.

[0034] like Figure 4As shown, the sealing groove 4121 is circumferentially arranged around the side wall of the plug head 412, and can be rectangular in cross-section. The groove depth is generally designed to be 3-5mm, and the groove width is determined according to the size of the annular sealing gasket 440. This ensures that the annular sealing gasket 440 is firmly embedded in the groove, while also ensuring that the gasket has sufficient deformation space under coolant pressure to achieve a good sealing effect. The annular sealing gasket 440 has a rectangular cross-sectional shape, which matches the shape of the sealing groove 4121. Its inner diameter is slightly smaller than the outer diameter of the plug head 412. During installation, a certain external force needs to be applied to fit it into the sealing groove 4121, causing the gasket to undergo a certain pre-compression deformation, thereby enhancing the sealing effect. The annular sealing gasket 440 can make tight contact with the side wall of the second cooling water channel 330 to form an effective sealing effect. In addition, the elastic sealing gasket 450 can be pasted to the lower end of the plug head 412 to further enhance its sealing performance and buffering effect. Under pressure, it can play an additional buffering role, further improving the sealing effect.

[0035] In addition, the water channel adjustment mechanism 400 includes a mounting bracket 430, which is fixed on the side mold body 300. The drive cylinder 420 is connected to the mounting bracket 430. There is a receiving space 431 between the mounting bracket 430 and the side mold body 300 along the axial direction of the side mold body 300. When the drive cylinder 420 is in the retracted state, the connecting rod 411 and the plug head 412 move to the receiving space 431 to open the second cooling water channel 330.

[0036] In this embodiment, as Figure 2 As shown, a mounting bracket 430 is connected to the upper end face of the side mold body 300. The mounting bracket 430 is placed vertically, and its bottom end is fixedly connected to the side mold. The drive cylinder 420 is installed on the upper end of the mounting bracket 430. In the vertical direction, there is a receiving space 431 between the upper end of the mounting bracket 430 and the upper end face of the side mold body 300. When the drive cylinder 420 retracts to its lowest point, the connecting rod 411 and the plug head 412 are separated from the second cooling water channel 330 and housed in the receiving space 431. This opens the upper opening of the second cooling water channel 330, allowing the second cooling water channel 330 to communicate with the outside. This allows the coolant to fill the entire second cooling water channel 330, improving the cooling effect and further increasing the cooling efficiency.

[0037] Specifically, the mold also includes multiple second cooling channels 330, which are evenly distributed along the circumference of the side mold body 300, and all the multiple second cooling channels 330 are located between the inlet 321 and the outlet 322.

[0038] In this embodiment, as Figure 3As shown, multiple second cooling channels 330 are provided, and the multiple second cooling channels 330 are evenly distributed along the circumference of the side mold body 300, which effectively improves the cooling uniformity of the side mold body 300. In addition, each second cooling channel 330 is equipped with a channel adjustment structure at its upper end, so that the effective cooling length of the second cooling channel 330 at different positions can be adjusted more flexibly to ensure the cooling capacity of the wheel hub.

[0039] In addition, an overflow groove 340 is provided on the end face of the side mold body 300 away from the first cooling water channel 320. The overflow groove 340 is connected to the opening of one end of the second cooling water channel 330 opposite to the first cooling water channel 320. An overflow groove 340 is also provided on the upper end face of the side mold body 300. The overflow groove 340 is a groove structure formed in the side mold body 300. The overflow groove 340 is connected to the upper opening of the multiple second cooling water channels 330. In this way, after the coolant fills the second cooling water channel 330, the coolant overflowing from the second cooling water channel 330 can be collected and guided, avoiding coolant overflow and pollution of the working environment and avoiding waste.

[0040] In the specific structure of the side mold body 300, such as Figure 3 As shown, the side mold body 300 includes at least four side modules 350, which are combined to form the side mold body 300. Each side module 350 includes a first cooling water channel 320, a second cooling water channel 330, and a water channel adjustment mechanism 400.

[0041] In this embodiment, the side mold body 300 adopts a modular design, including four side modules 350. Each side module 350 has a relatively simple structure, which facilitates mass production and processing. Compared with the integral side mold body 300, this reduces manufacturing difficulty and processing costs. During mold use, if a side module 350 malfunctions, such as a blocked cooling channel or damage to the channel adjustment mechanism 400, only that side module 350 needs to be disassembled and replaced individually, without needing to repair the entire side mold body 300, greatly shortening maintenance time and reducing maintenance costs. Each side module 350 is equipped with an independent first cooling channel 320, a second cooling channel 330, and a channel adjustment mechanism 400, which allows for individual adjustment of the cooling parameters of each side module 350 according to the actual cooling needs of different parts of the wheel hub.

[0042] In addition, the mold also includes a control module 510, a temperature monitoring module 520, and a flow control valve 530. The flow control valve 530 is connected to the water inlet 321. The temperature monitoring module 520 is connected to the side mold body 300 and located on one side of the molding space 310. The temperature monitoring module 520 and the flow control valve 530 are both connected to the control module 510. The control module 510 is connected to the water channel adjustment mechanism 400. The temperature monitoring module 520 is used at least to monitor the temperature of the wheel hub and transmit the temperature signal to the control module 510. The control module 510 receives the temperature signal and controls the water channel adjustment mechanism 400 to drive the telescopic plug 410 to move. The control module 510 controls the flow control valve 530 to adjust the flow rate of the water inlet 321.

[0043] In this embodiment, as Figure 5 As shown, before the wheel hub mold starts working, the operator inputs the specifications of the wheel hub to be produced, including wheel hub size and structural characteristics, into the control module 510. The control module 510 determines the corresponding temperature control range and coolant flow adjustment strategy according to the preset program and these parameters. The flow control valve 530 is adjusted to a suitable opening to ensure that the coolant enters the first cooling water channel 320 at an appropriate flow rate. The drive electric cylinder 420 in the water channel adjustment mechanism 400 adjusts the plug head 412 to the corresponding position according to the initial settings to determine the initial effective cooling length of the second cooling water channel 330. During the wheel hub forming process, the temperature monitoring module 520 measures the temperature of different parts of the wheel hub in real time and transmits the temperature signal to the control module 510. The control module 510 receives these temperature signals in real time, analyzes and processes them. If the temperature of a certain area is higher than the target temperature range, the control module 510 sends a control signal to the flow control valve 530 to increase the opening, allowing more coolant to flow into the first cooling water channel 320. At the same time, it sends a contraction command to the drive cylinder 420 of the water channel adjustment mechanism 400, causing the plug head 412 to move, increasing the effective cooling length of the second cooling water channel 330, thereby improving the cooling efficiency of that area. If the temperature of a certain area is lower than the target temperature range, the control module 510 sends a signal to the flow control valve 530 to decrease the opening, reducing the coolant flow, and controls the drive cylinder 420 to extend, reducing the effective cooling length of the second cooling water channel 330.

[0044] The temperature monitoring module 520 monitors the wheel hub temperature in real time and accurately, while the control module 510 adjusts the cooling system parameters promptly and precisely based on temperature changes, ensuring temperature uniformity of the wheel hub during the forming process. This automated process reduces manual intervention and the labor intensity of operators, while also improving the stability and consistency of the production process, achieving precise temperature control and efficient cooling system operation.

[0045] In addition, the inner plate of the upper mold body 100 is provided with a first cooling pipe 110, and the inner plate of the lower mold body 200 is provided with a second cooling pipe 210.

[0046] In this embodiment, as Figure 1 As shown, a first cooling pipe 110 is provided within the upper mold body 100, and the first cooling pipe 110 is distributed in an "S" shape or a spiral shape. Similarly, a second cooling pipe 210 is provided within the lower mold body 200, and the second cooling pipe 210 can also be distributed in an "S" shape or a spiral shape. This further improves the cooling effect on the wheel hub.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
