Description

Technical Field

[0001] The present invention belongs to the technical field of truck axle housing processing, and particularly relates to a forming device for a heavy truck integrated axle cap and axle housing body. Background Art

[0002] The axle housing is a mounting matrix for the main reducer, differential, half shaft, and wheel assembly. Its main function is to support and protect the main reducer, differential, half shaft, etc. Generally, the ordinary non-disconnecting drive axle housing is a rigid hollow beam supported on the left and right drive wheels. Transmission components such as the main reducer, differential, and half shaft are all installed therein. The axle housing is connected to the frame or carriage through longitudinally arranged leaf springs. It is an important part of the drive axle and also one of the main components of the running system.

[0003] When casting and processing the existing integrated axle cap and axle housing of a truck, it is usually necessary to wait for the axle housing body in the casting mold to cool down before continuing to use the casting mold for casting the integrated axle cap and axle housing of the truck. The processing efficiency it can achieve is very limited; and when it is necessary to demold the integrated axle cap and axle housing in the mold, it is also necessary to specifically design a corresponding ejection mechanism on the mold, which increases the manufacturing difficulty and cost of the mold and cannot automatically demold the integrated axle cap and axle housing in the mold quickly; at the same time, when cooling the casting mold, a large amount of cooling water is required for cooling. When a large amount of cooling water dissipates heat, it requires a large area, and it is impossible to reduce the floor area of the entire forming device for the integrated axle cap and axle housing of the truck while ensuring the cooling effect of the casting mold. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a forming device for a heavy truck integrated axle cap and axle housing body.

[0005] The technical solution adopted to solve the above technical problem is: A forming device for a heavy truck integrated axle cap and axle housing body, including a water storage bin and a first C-shaped frame. A casting switching mechanism is arranged at the top of the water storage bin. An upper mold mechanism is arranged inside the casting switching mechanism. An automatic lifting mechanism that cooperates with the upper mold mechanism is arranged at the inner top of the casting switching mechanism. A lower mold mechanism that cooperates with the upper mold mechanism is arranged at a non-central position at the inner bottom of the casting switching mechanism. A water cooling mechanism and a temperature reduction mechanism are respectively arranged on the outer side of the first C-shaped frame.

[0006] Furthermore, the casting switching mechanism includes a support tube located at the center position of the top of the water storage tank, a rotating disk that can rotate around a fixed axis is provided at the top of the support tube, a vertical tube is installed at the center position of the top of the rotating disk, a connecting disk is installed at the middle position of the outside of the vertical tube, a connecting bearing fixedly connected to the outside of the vertical tube is installed at the inner top of the first U-shaped frame, and a driving device for driving the vertical tube to rotate is provided at the top of the first U-shaped frame.

[0007] Through the above technical solution, the control driving device drives the vertical tube to rotate 45° counterclockwise each time, so that the rotating disk and the connecting disk can rotate synchronously, while the support tube will not rotate. This also allows each pair of upper casting molds and lower casting molds on the rotating disk to continuously switch positions, making it convenient to continuously inject the bridge cap integrated bridge shell raw materials into each set of upper casting molds and lower casting molds, ensuring that the entire molding device continuously processes and produces the bridge cap integrated bridge shell finished products.

[0008] Furthermore, the upper mold mechanism includes a lifting platform, which is provided with eight groups of lifting platforms, and a first sliding rod is inserted at the four corners of the eight groups of lifting platforms. The top and bottom of the first sliding rod are respectively fixedly connected to the connecting disk and the rotating disk. An upper casting mold is installed inside the lifting platform, and a first water cooling channel is provided inside the upper casting mold. A casting inlet and an exhaust port are respectively provided at the middle position of the top of the upper casting mold.

[0009] Through the above technical solution, the bridge cap integrated bridge shell material can be injected into the cavity between the upper casting mold and the lower casting mold through the casting inlet, and the exhaust port helps to discharge the air in the cavity between the upper casting mold and the lower casting mold from the casting inlet, which also helps the bridge cap integrated bridge shell material to enter the cavity between the upper casting mold and the lower casting mold more easily. The first water cooling channel can allow cooling water to pass through the interior of the upper casting mold to cool it.

[0010] Furthermore, the automatic lifting mechanism includes a limit plate mounted on the outside of the vertical tube, the top of the limit plate is fixedly connected to the inner top of the first U-shaped frame, the top of the upper casting mold is installed with a U-shaped lifting rod, the top of the U-shaped lifting rod is installed with two groups of second sliding rods, and the top ends of the two groups of second sliding rods extend to the top of the connecting plate and are jointly installed with a guide wheel that cooperates with the limit plate, and the outer side of the second sliding rod is provided with a reset spring, and the top and bottom of the reset spring are fixedly connected to the connecting plate and the U-shaped lifting rod respectively.

[0011] Through the above technical solution, when the rotating disk and the connecting disk rotate synchronously, the guide wheel rolls on the edge protrusion of the limit disk. During the process of the guide wheel rolling to the highest point of the edge protrusion of the limit disk, the U-shaped lifting rod and the second sliding rod descend together until the upper casting mold and the lower casting mold are completely closed, and the reset tension spring is stretched under force. During the process of the guide wheel rolling to the lowest point of the edge protrusion of the limit disk, the pulling force of the reset tension spring pulls the upper casting mold to gradually separate from the lower casting mold.

[0012] Further, the lower mold mechanism includes eight square through holes located at non-central positions on the top of the rotating disk. The lower casting mold is arranged inside the square through hole through a bearing seat, and a second water cooling channel that cooperates with the first water cooling channel is arranged inside the lower casting mold. A turning-over component that cooperates with the lower casting mold is arranged at the top outside the support pipe. One end of the lower casting mold is provided with an output pipe that cooperates with the bearing seat, and the end of the output pipe far from the lower casting mold extends to the outside of the rotating disk. The end of the output pipe close to the lower casting mold is communicated with one end inside the second water cooling channel.

[0013] [[ID=⑥]]Through the above technical solution, during the process of the cooling water in the first water cooling channel flowing to the second water cooling channel, it can play a good cooling effect on the lower casting mold. During the process of the lower casting mold rotating with the rotating disk, in cooperation with the turning-over component, the effect of making the lower casting mold rotate one circle around the output pipe can be achieved. During this process, the bridge cap integral bridge shell in the casting groove of the lower casting mold can leave the inside of the lower casting mold under the action of gravity.

[0014] Further, the turning-over component includes an inner ring frame located at the top outside of the support pipe. An outer ring frame is installed on the outer circle of the inner ring frame, and guide rollers are evenly installed on the top of the outer ring frame. A fan-shaped notch is opened at the position on the top of the outer ring frame close to the first C-shaped frame. An arc-shaped rack is installed at the position on the top of the inner ring frame close to the fan-shaped notch. A passive gear that cooperates with the arc-shaped rack is installed on the outer side of the rotating shaft at the end of the lower casting mold far from the output pipe.

[0015] Through the above technical solution, during the process of the lower casting mold rotating with the rotating disk, the bottom of the lower casting mold always rolls on a number of guide rollers, ensuring the stability of the casting groove of the lower casting mold facing upwards. When the lower casting mold rotates past the fan-shaped notch, the arc-shaped rack and the passive gear cooperate to drive the lower casting mold to rotate one circle around the output pipe. During this process, the finished product of the bridge cap integral bridge shell in the lower casting mold will automatically fall, realizing the function of automatic discharging.

[0016] Further, the water cooling mechanism includes a water pump located at the top of the water storage bin. Both the top and bottom of the outer side of the first U-shaped frame are equipped with horizontal pipes, and a plurality of radiating pipes are evenly installed between the two groups of horizontal pipes. The top end inside the vertical pipe is provided with a water supply component for supplying water to the first water cooling channel. A connecting pipe is installed on the outer side of the top group of horizontal pipes, and the output end of the connecting pipe is communicated with the input end of the water supply component. The bottom end inside the rotating disk is provided with a water return component for recovering the cooling water inside the second water cooling channel. The input end of the water pump is communicated with the edge position at the inner bottom of the water storage bin, and the output end of the water pump is communicated with the inside of the bottom group of horizontal pipes.

[0017] Through the above technical solution, the water pump is controlled to sequentially pass the cooling water inside the water storage bin through the horizontal pipes, radiating pipes, connecting pipes and water supply components and then enter the first water cooling channels of each upper casting mold. After that, the cooling water then passes through the second water cooling channels of the lower casting molds. During this process, the cooling water cools the upper casting molds and the lower casting molds. Subsequently, the cooling water then sequentially passes through the output pipes and the water return components and then returns to the inside of the water storage bin, realizing the recycling of the cooling water inside the water storage bin. And during the process of the cooling water passing through the inside of the radiating pipes, the heat dissipation effect of the cooling water can be improved.

[0018] Further, the water supply component includes a first rotary joint located at the inner top of the vertical pipe. The input end of the upper casting mold is installed with a water supply pipe through a three-way solenoid valve. The input ends of the eight water supply pipes extend to the inner top of the vertical pipe and are jointly installed with a first collecting bin. The output end of the first rotary joint is communicated with the inner top of the first collecting bin.

[0019] Through the above technical solution, the cooling water enters the first collecting bin after passing through the first rotary joint through the connecting pipe. After that, the cooling water then enters the first water cooling channel of the upper casting mold through the water supply pipe and the three-way solenoid valve, performing water cooling on the upper casting mold.

[0020] Further, the water return component includes a second rotary joint located at one end of the output pipe. The output end of the second rotary joint is installed with a water return pipe. The output end of the water return pipe extends to the inner bottom of the vertical pipe and is jointly installed with a second collecting bin. The bottom of the second collecting bin is installed with a third rotary joint communicated with the inner top of the water storage bin.

[0021] Through the above technical solution, after the cooling water passes through the second water cooling channel inside the lower casting mold, the cooling water then sequentially passes through the second rotary joint and the water return pipe and enters the second collecting bin. After that, it then returns to the inside of the water storage bin through the third rotary joint. And the second rotary joint can stably transport the cooling water back to the inside of the water storage bin on the premise of not affecting the rotation of the lower casting mold.

[0022] Furthermore, the cooling mechanism includes a second V-shaped frame located outside the first V-shaped frame, and four groups of cooling fans are arranged on the outside of the second V-shaped frame from top to bottom. A first vertical pipe and a second vertical pipe are respectively installed on one side of the second V-shaped frame, and the second vertical pipe is connected to the interior of the first vertical pipe. Water pipes are evenly arranged between the heat dissipation pipe and the second V-shaped frame, and one end of the water pipe is connected to the interior of the first vertical pipe. Spray heads are evenly installed on the outside of the second vertical pipe and the water pipe. A water supply pump is installed at the bottom of the second V-shaped frame, and the input end of the water supply pump is connected to the output end of the external water pipe, and the output end of the water supply pump is connected to the inner bottom of the first vertical pipe.

[0023] Through the above technical solution, the water supply pump is controlled to transport the external cooling water into the first vertical pipe, and then the spray head on the second vertical pipe sprays and cools the upper casting mold and the lower casting mold passing through, while the spray head on the water spray pipe sprays the surface of several groups of heat dissipation pipes. At the same time, the cooling fan is controlled to blow air to cool the several groups of heat dissipation pipes. Through the coordination of air cooling and spray cooling, the temperature of the cooling water after passing through the heat dissipation pipe can be quickly reduced, thereby ensuring the subsequent cooling effect of the cooling water on the upper casting mold and the lower casting mold.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention drives eight groups of upper casting molds and lower casting molds to continuously rotate with the support tube as the axis through the casting switching mechanism, so that each group of upper casting molds and lower casting molds automatically switches positions. When the casting material is injected into a group of upper casting molds and lower casting molds, the upper casting molds and lower casting molds that have been injected with the casting material can also be cooled down. In the process of the rotation of the rotating disk, the upper casting molds and lower casting molds can also be automatically closed or separated, thereby helping to improve the efficiency of the entire molding device in processing the integrated bridge shell of the heavy-duty truck bridge cap; (2) The present invention cooperates with the casting switching mechanism and the lower mold mechanism, and in the process of driving the lower casting mold to rotate and switch positions, the lower casting mold can also be automatically closed or separated. The movable flipping surface realizes the function of automatic demoulding of the finished product of the bridge cap integrated bridge shell, and there is no need to design a special product ejection structure for the lower casting mold, thereby reducing the manufacturing difficulty and cost of the lower casting mold, and reducing the difficulty of repairing the lower casting mold; (3) The present invention uses a water cooling mechanism and a cooling mechanism in conjunction with each other, which can not only quickly cool the upper casting mold and the lower casting mold through the water cooling mechanism, but also quickly dissipate the cooling water used for cooling in the water cooling mechanism through the cooling mechanism, thereby ensuring the cooling effect of the water cooling mechanism on the upper casting mold and the lower casting mold, and the cooling mechanism can also spray the upper casting mold and the lower casting mold to cool down, while ensuring the cooling effect on the casting mold and reducing the footprint of the entire truck bridge cap integrated bridge shell forming device.

[0046] As Figures 1-8As shown, a heavy-duty truck bridge cap integrated bridge shell body forming device of this embodiment includes a water storage tank 1 and a first U-shaped frame 2. A casting switching mechanism 3 is provided on the top of the water storage tank 1. The casting switching mechanism 3 includes a support tube 301 located at the center position of the top of the water storage tank 1. A rotating disk 302 that can rotate around a fixed axis is provided on the top of the support tube 301. A vertical tube 303 is installed at the center position of the top of the rotating disk 302. A connecting disk 304 is installed at the middle position of the outer side of the vertical tube 303. A connecting bearing 305 fixedly connected to the outer side of the vertical tube 303 is installed on the inner top of the first U-shaped frame 2. A driving device 306 for driving the vertical tube 303 to rotate is provided on the top of the first U-shaped frame 2. The driving device 306 includes a U-shaped frame 3061 located on the top of the limit plate 501. A driven gear is installed on the top of the outer side of 303. 3062. A servo motor 3063 is installed on the top of the U-shaped frame 3061, and a driving gear 3064 meshing with the driven gear 3062 is installed on the output end of the servo motor 3063. The U-shaped frame 3061 is controlled to drive the driving gear 3064 to rotate, and the transmission of the driving gear 3064 and the driven gear 3062 is used to drive the vertical tube 303 to rotate 45° counterclockwise each time, so that the rotating disk 302 and the connecting disk 304 can rotate synchronously, while the support tube 301 will not rotate, so that each pair of upper casting molds 403 and lower casting molds 604 on the rotating disk 302 can continuously switch positions, so as to facilitate the continuous injection of bridge cap integrated bridge shell raw materials into each group of upper casting molds 403 and lower casting molds 604, to ensure that the entire molding device can continuously process and produce bridge cap integrated bridge shell finished products.

[0047] like Figures 1-13As shown, the casting switching mechanism 3 of this embodiment is provided with an upper mold mechanism 4 inside, and an automatic lifting mechanism 5 that cooperates with the upper mold mechanism 4 is provided on the top of the casting switching mechanism 3. The upper mold mechanism 4 includes a lifting platform 402, and the lifting platform 402 is provided with eight groups. The four corners of the eight groups of lifting platforms 402 are all inserted with a first slide bar 401. The top and bottom of the first slide bar 401 are fixedly connected to the connecting disk 304 and the rotating disk 302 respectively. The upper casting mold 403 is installed inside the lifting platform 402. A first water cooling channel 404 is provided inside the upper casting mold 403, a casting inlet 405 and an exhaust port 406 are respectively provided at the middle position of the top of the upper casting mold 403, the automatic lifting mechanism 5 includes a limit plate 501 sleeved on the outside of the vertical tube 303, the top of the limit plate 501 is fixedly connected to the inner top of the first U-shaped frame 2, a U-shaped lifting rod 502 is installed on the top of the upper casting mold 403, and two groups of second slide bars 503 are installed on the top of the U-shaped lifting rod 502, and the top ends of the two groups of second slide bars 503 extend to the top of the connecting plate 304 and A guide wheel 504 is installed together with the limit plate 501, and a reset spring 505 is provided on the outer side of the second slide bar 503. The top and bottom of the reset spring 505 are fixedly connected to the connecting plate 304 and the U-shaped lifting rod 502 respectively. When the rotating disk 302 and the connecting disk 304 rotate synchronously, the guide wheel 504 rolls on the edge protrusion of the limit plate 501. When the guide wheel 504 rolls to the highest point of the edge protrusion of the limit plate 501, the U-shaped lifting rod 502 descends with the second slide bar 503 until the upper casting mold 4 03 and the lower casting mold 604 are completely closed, and the reset tension spring 505 is stretched by force. At this time, the bridge cap integrated bridge shell material is injected into the cavity between the upper casting mold 403 and the lower casting mold 604, and the exhaust port 406 helps to allow the casting inlet 405 to discharge the air in the cavity between the upper casting mold 403 and the lower casting mold 604. In the process of the guide wheel 504 rolling to the lowest point of the protrusion on the edge of the limit plate 501, the tension of the reset tension spring 505 pulls the upper casting mold 403 to gradually separate from the lower casting mold 604.

[0048] like Figure 3-Figure 6 、 Figure 10-11 and Figure 14As shown in the figure, a lower mold mechanism 6 that cooperates with the upper mold mechanism 4 is provided at a non - central position at the bottom inside the casting switching mechanism 3 of this embodiment. The lower mold mechanism 6 includes eight square through - holes 601 located at non - central positions on the top of the rotating disk 302. Inside the square through - holes 601, a lower casting mold 604 is provided through a bearing seat 602. And inside the lower casting mold 604, a second water - cooling channel 605 that cooperates with the first water - cooling channel 404 is provided. At the top outside the support tube 301, a turning - over component 606 that cooperates with the lower casting mold 604 is provided. One end of the lower casting mold 604 is equipped with an output pipe 603 that cooperates with the bearing seat 602, and the end of the output pipe 603 away from the lower casting mold 604 extends to the outside of the rotating disk 302. One end of the output pipe 603 close to the lower casting mold 604 is connected to one end inside the second water - cooling channel 605. The turning - over component 606 includes an inner ring frame 6061 at the outer top of the support tube 301. An outer ring frame 6063 is installed on the outer circle of the inner ring frame 6061, and guide rollers 6064 are evenly installed on the top of the outer ring frame 6063. A sector - shaped notch 6065 is opened at a position on the top of the outer ring frame 6063 close to the first C - shaped frame 2. An arc - shaped rack 6062 is installed at a position on the top of the inner ring frame 6061 close to the sector - shaped notch 6065. A passive gear 6066 that cooperates with the arc - shaped rack 6062 is installed on the outer side of the rotating shaft at one end of the lower casting mold 604 away from the output pipe 603. During the process of the lower casting mold 604 rotating with the rotating disk 302, the bottom of the lower casting mold 604 is always rolling on a number of guide rollers 6064, ensuring the stability of the casting groove of the lower casting mold 604 facing upwards. And when the lower casting mold 604 rotates past the sector - shaped notch 6065, the arc - shaped rack 6062 cooperating with the passive gear 6066 will drive the lower casting mold 604 to rotate one circle with the output pipe 603 as the axis. During this process, the finished bridge - cap integral bridge housing inside the lower casting mold 604 will automatically fall, realizing the function of automatic discharging. And during the process of the cooling water in the first water - cooling channel 404 flowing to the second water - cooling channel 605, it can play a good role in cooling the lower casting mold 604.

[0049] As Figure 4-Figure 5 , Figure 8-Figure 9 and Figures 15-19As shown in the figure, a water cooling mechanism 7 and a cooling mechanism 8 are respectively arranged on the outer side of the first C-shaped frame 2 of this embodiment. The water cooling mechanism 7 includes a water pump 705 located at the top of the water storage bin 1. Horizontal pipes 701 are installed at the top and bottom of the outer side of the first C-shaped frame 2, and heat dissipation pipes 702 are evenly installed between the two groups of horizontal pipes 701. A water supply component 704 for supplying water to the first water cooling channel 404 is arranged at the top end inside the vertical pipe 303. A connecting pipe 703 is installed on the outer side of the upper group of horizontal pipes 701, and the output end of the connecting pipe 703 is communicated with the input end of the water supply componentThen the cooling water enters the second collecting chamber 7063 through the output pipe 603, the second rotary joint 7061 and the return pipe 7062 in sequence, and then returns to the interior of the water storage tank 1 through the third rotary joint 7064. The second rotary joint 7061 stably transports the cooling water back to the interior of the water storage tank 1 without affecting the rotation of the lower casting mold 604, thereby realizing the recycling of the cooling water in the water storage tank 1. In the process of the cooling water passing through the heat dissipation pipe 702, the heat dissipation effect of the cooling water can be improved. At the same time, the water supply pump 807 is controlled to output the external cooling water. The cooling water is then sent to the first vertical pipe 803. The spray head 806 on the second vertical pipe 804 then sprays the cooling water on the upper casting mold 403 and the lower casting mold 604. The spray head 806 on the water spray pipe 805 sprays the surface of the groups of heat pipes 702. Simultaneously, the cooling fan 802 is controlled to blow air on the groups of heat pipes 702 to cool them. The combined cooling of air and spray can quickly reduce the temperature of the cooling water after it passes through the heat pipes 702, thereby ensuring the cooling effect of the cooling water on the upper casting mold 403 and the lower casting mold 604.

[0050] like Figures 9-11As shown, the first water-cooling channel 404 of this embodiment includes first U-shaped through grooves 4041 located at both ends of the interior of the upper casting mold 403, and the two groups of first U-shaped through grooves 4041 are interconnected through a plurality of groups of first connecting through grooves 4042. The plurality of groups of first connecting through grooves 4042 are evenly distributed on both sides of the interior of the upper casting mold 403. One end of the top of the upper casting mold 403 is equipped with a water inlet joint 4043 that is connected to the interior of the adjacent group of first U-shaped through grooves 4041. 03 bottom away from the water inlet connector 4043 is provided with a connecting socket 4044 connected to the inside of another set of first U-shaped grooves 4041. The top of the water inlet connector 4043 is connected to the output end of the three-way solenoid valve 7044. The second water cooling channel 605 includes second U-shaped grooves 6051 located at both ends of the lower casting mold 604, and the two sets of second U-shaped grooves 6051 are connected to each other through a plurality of sets of second connecting grooves 6052. The top of the lower casting mold 604 is away from the output pipe 606. One end of 03 is equipped with a connecting plug 6053 that cooperates with the connecting socket 4044, and the connecting plug 6053 is connected to the interior of an adjacent set of second U-shaped grooves 6051. After the water supply pipe 7043 delivers cooling water to the interior of a set of first U-shaped grooves 4041 through the three-way solenoid valve 7044, the cooling water flows into the other set of first connecting grooves 4042 through the first connecting grooves 4042, and then the cooling water enters the water supply pipe 7043 through the connecting socket 4044 and the connecting plug 6053. A group of second U-shaped grooves 6051, and then the cooling water enters the second group of second U-shaped grooves 6051 through the second connecting groove 6052, and then the cooling water passes through the output pipe 603 and the second rotary joint 7061 and enters the return pipe 7062. In this process, the cooling water can cool the upper casting mold 403 and the lower casting mold 604, thereby helping to quickly cool and form the bridge cap integrated bridge shell in the cavity between the upper casting mold 403 and the lower casting mold 604.

[0051] like Figure 1-Figure 5 As shown, the top of the connecting disk 304 of this embodiment is equipped with a protective shell 9 that covers the limit disk 501, and the top of the outer side of the support tube 301 is equipped with a guide hopper 10, and the guide hopper 10 is located directly below the fan-shaped notch 6065. The protective shell 9 can be used to completely cover the partial structure of the automatic lifting mechanism 5 located above the connecting disk 304, which is not only beautiful, but also can prevent foreign matter from accidentally entering the top of the connecting disk 304 and affecting the normal lifting of the lifting platform 402. When a pair of upper casting molds 403 and lower casting molds 604 are rotated to directly above the guide hopper 10, the lower casting mold 604 will automatically turn over and discharge the bridge cap integrated bridge shell formed inside the lower casting mold 604, and the guide hopper 10 can catch the fallen bridge cap integrated bridge shell and guide it into a bin body specially used to collect the bridge cap integrated bridge shell.

[0052] like Figure 15-16 and Figure 18 As shown in the figure, a recycling device 11 is provided on the inner bottom of the second C-shaped frame 801 of this embodiment. The recycling device 11 includes a collection bin and a drainage hose. The output end of the drainage hose is connected to an external collection pool, and the input end of the drainage hose is connected to the inner bottom of the collection bin. After the water mist sprayed by some spray heads 806 contacts the outer side of the first C-shaped frame 2, it gradually flows downward and enters the collection bin at the inner bottom of the second C-shaped frame 801. Then, the collected water is discharged into the external collection pool through the drainage hose. The water collected in the external collection pool can be used again for spraying water to cool the heat dissipation pipe 702, improving the utilization rate of water resources.

[0053] The working principle of this embodiment is as follows: the position where a group of square through holes 601 are located opposite the first shaped frame 2 is set as the first processing position, firstly, the material for casting the bridge cap integrated bridge shell is injected into the casting inlet 405 on the first work station, and the bridge cap integrated bridge shell raw material enters the casting cavity formed by the upper casting mold 403 and the lower casting mold 604 through the casting inlet 405. After the group of casting cavities is filled with the bridge cap integrated bridge shell raw material, the servo motor 3063 is controlled to drive the rotating disk 302 to rotate 45° counterclockwise each time, so that each pair of upper casting molds 403 and lower casting molds 604 pass through the first processing position one after another. After each pair of upper casting molds 403 and lower casting molds 604 leave the first processing position, the water pump 705 is controlled to pump the water inside the water storage tank 1. The cooling water passes through the horizontal pipe 701, the heat dissipation pipe 702, the connecting pipe 703 and the first rotary joint 7041 in sequence and enters the first collecting chamber 7042. Then, the water supply pipe 7043 cooperates with the three-way solenoid valve 7044 to deliver it to the first water cooling channel 404 of each group of upper casting molds 403. After that, the cooling water passes through the second water cooling channel 605 of the lower casting mold 604. During the process, the cooling water cools down the upper casting mold 403 and the lower casting mold 604. Then, the cooling water passes through the output pipe 603, the second rotary joint 7061, the return pipe 7062, the second collecting chamber 7063 and the third rotary joint 7064 in sequence and returns to the inside of the water storage tank 1. During the counterclockwise rotation of the rotating disk 302, each pair of upper casting molds 4 03 and the lower casting mold 604 are first in a closed mold state, and then gradually separated. In the process of the lower casting mold 604 passing above the fan-shaped notch 6065, the lower casting mold 604 is turned over to the casting groove facing downward due to the cooperation of the arc-shaped rack 6062 and the passive gear 6066, and the cast bridge cap integrated bridge shell is discharged. Then, the lower casting mold 604 is rotated again to the casting groove facing upward. Subsequently, when the lower casting mold 604 continues to rotate with the support tube 301 as the axis, its bottom will continue to slide on the multiple sets of guide rollers 6064. In the process of casting the bridge cap integrated bridge shell through the upper casting mold 403 and the lower casting mold 604, it is also necessary to control the water supply pump 807 to transport the external cooling water into the first vertical pipe 803, and then by the second The spray head 806 on the vertical pipe 804 sprays and cools the upper casting mold 403 and the lower casting mold 604 passing by, while the spray head 806 on the water spray pipe 805 sprays the surface of the several groups of heat pipes 702. At the same time, the cooling fan 802 is controlled to blow air to cool the several groups of heat pipes 702. Whenever the upper casting mold 403 and the lower casting mold 604 are about to be separated, the three-way solenoid valve 7044 on the upper casting mold 403 is controlled to close the water supply pipe 7043 and open another interface to allow outside air to enter the first water cooling channel 404 and the second water cooling channel 605, thereby allowing all the cooling water inside the first water cooling channel 404 and the second water cooling channel 605 to return to the interior of the water storage tank 1.After the upper casting mold 403 and the lower casting mold 604 are closed and leave the first processing position, the water supply end of the three-way solenoid valve 7044 is opened and the air inlet end is closed.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
