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 bridge cap integrated 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, a common 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 truck bridge cap integrated axle housing, 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 truck bridge cap integrated axle housing. The processing efficiency it can achieve is very limited. And when it is necessary to demold the bridge cap integrated axle housing in the mold, it is also necessary to specially design a corresponding ejection mechanism on the mold, which increases the manufacturing difficulty and cost of the mold and cannot automatically demold the bridge cap integrated 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 truck bridge cap integrated axle housing 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 bridge cap integrated axle housing body.

[0005] The technical solution adopted to solve the above technical problem is: a forming device for a heavy truck bridge cap integrated axle housing body, including a water storage tank and a first C-shaped frame. A casting switching mechanism is arranged on the top of the water storage tank. 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] Further, the casting switching mechanism includes a support pipe located at the center position of the top of the water storage bin. A rotatable turntable is provided at the top of the support pipe. A vertical pipe is installed at the center position of the top of the turntable. A connecting disk is installed at the middle position of the outer side of the vertical pipe. A connecting bearing fixedly connected to the outer side of the vertical pipe is installed at the inner top of the first C-shaped frame. A driving device for driving the vertical pipe to rotate is provided at the top of the first C-shaped frame.

[0007] Through the above technical solution, by controlling the driving device to drive the vertical pipe to rotate counterclockwise by 45° each time, the turntable and the connecting disk can be synchronously rotated, while the support pipe does not rotate. In this way, each pair of upper casting molds and lower casting molds on the turntable can continuously switch positions, facilitating the continuous injection of the bridge cap integrated bridge shell raw material into each group of upper casting molds and lower casting molds, and ensuring that the entire forming device continuously processes and produces the bridge cap integrated bridge shell finished products.

[0008] Further, the upper mold mechanism includes a lifting table. There are eight groups of lifting tables, and first sliding rods are inserted at the four corner positions of the eight groups of lifting tables. The top and bottom of the first sliding rods are respectively fixedly connected to the connecting disk and the turntable. An upper casting mold is installed inside the lifting table. 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 raw 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 is more conducive to the bridge cap integrated bridge shell raw material entering the cavity between the upper casting mold and the lower casting mold more easily. The first water cooling channel can allow the cooling water to pass through the inside of the upper casting mold to cool it down.

[0010] Further, the automatic lifting mechanism includes a limiting disk sleeved on the outer side of the vertical pipe. The top of the limiting disk is fixedly connected to the inner top of the first C-shaped frame. A U-shaped lifting rod is installed at the top of the upper casting mold. Two second sliding rods are installed at the top of the U-shaped lifting rod, and the tops of the two second sliding rods extend above the connecting disk and are jointly installed with a guide wheel that cooperates with the limiting disk. A return tension spring is sleeved on the outer side of the second sliding rod. The top and bottom of the return tension spring are respectively fixedly connected to the connecting disk and the U-shaped lifting rod.

[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 drives the second sliding rod to 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 groups of 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 holes through bearing seats, and a second water cooling channel is arranged inside the lower casting mold and is matched with the first water cooling channel. A turning-over component matched 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 matched with the bearing seat, and the end of the output pipe away from the lower casting mold extends to the outside of the rotating disk. One end of the output pipe close to the lower casting mold is communicated with one end inside the second water cooling channel.

[0013] 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, the turning-over component can be used to realize the effect that the lower casting mold rotates one circle with the output pipe as the axis. During this process, the bridge cap integrated 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 sector-shaped notch is formed at the position of the top of the outer ring frame close to the first C-shaped frame. An arc-shaped rack is installed at the position of the top of the inner ring frame close to the sector-shaped notch. A passive gear matched with the arc-shaped rack is installed on the outer side of the rotating shaft at the end of the lower casting mold away 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 has been rolling on several groups of guide rollers to ensure the stability of the casting groove of the lower casting mold facing upward. When the lower casting mold rotates above the sector-shaped notch, the arc-shaped rack and the passive gear will drive the lower casting mold to rotate one circle with the output pipe as the axis. During this process, the finished product of the bridge cap integrated 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 C-shaped frame are equipped with horizontal pipes, and a plurality of cooling 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 horizontal pipe in a group, 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 bottom inside the water storage bin, and the output end of the water pump is communicated with the inside of the bottom horizontal pipe in a group.

[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, cooling 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 mold. During this process, the cooling water cools the upper casting mold and the lower casting mold. Subsequently, the cooling water then sequentially passes through the output pipe and the water return component 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 cooling pipe, 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. A third rotary joint communicating with the inner top of the water storage bin is installed at the bottom of the second collecting 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 stably conveys 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] Further, the cooling mechanism includes a second U-shaped frame located outside the first U-shaped frame. Four groups of cooling fans are sequentially arranged from top to bottom on the outside of the second U-shaped frame. A first vertical pipe and a second vertical pipe are respectively installed on one side of the second U-shaped frame, and the inside of the second vertical pipe is communicated with that of the first vertical pipe. Spray pipes are evenly arranged between the cooling pipes and the second U-shaped frame. One end of each spray pipe is communicated with the inside of the first vertical pipe. Spray heads are evenly installed on the outside of the second vertical pipe and the spray pipes. A water supply pump is installed at the bottom of the second U-shaped frame, and the input end of the water supply pump is communicated with the output end of an external water pipe, and the output end of the water supply pump is communicated with the inner bottom of the first vertical pipe.

[0023] Through the above technical solution, the water supply pump is controlled to convey the external cooling water into the first vertical pipe. Then, the spray heads on the second vertical pipe spray and cool the upper casting mold and the lower casting mold passing by. The spray heads on the spray pipes spray the surfaces of several groups of cooling pipes. At the same time, the cooling fans are controlled to blow and cool several groups of cooling pipes. Through the cooperation of air cooling and spray cooling, the temperature of the cooling water after passing through the cooling pipes 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 around the support pipe through the casting switching mechanism, so that each group of upper casting molds and lower casting molds automatically switches positions. When injecting casting materials into the upper casting mold and the lower casting mold, the upper casting mold and the lower casting mold that have already been injected with casting materials can be cooled. And during the rotation of the rotating disc, the upper casting mold and the lower casting mold can be automatically closed or opened, which helps to improve the processing efficiency of the entire forming device for the heavy truck bridge cap integrated bridge housing; (2) Through the cooperation of the casting switching mechanism and the lower mold mechanism, during the process of driving the lower casting mold to rotate and switch positions, the lower casting mold can be automatically turned over to realize the function of automatically demolding the finished product of the bridge cap integrated bridge housing, 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 at the same time reducing the maintenance difficulty of the lower casting mold; (3) Through the combined use of the water cooling mechanism and the cooling mechanism, the upper casting mold and the lower casting mold can be quickly cooled by water cooling through the water cooling mechanism, and the cooling water used for cooling in the water cooling mechanism can be quickly dissipated by the cooling mechanism, ensuring the cooling effect of the water cooling mechanism on the upper casting mold and the lower casting mold. Moreover, the cooling mechanism can also spray and cool the upper casting mold and the lower casting mold, while ensuring the cooling effect on the casting mold, reducing the floor area of the entire truck bridge cap integrated bridge housing forming device.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] As Figures 1-8As shown in the figure, a forming device for the integral axle housing body of a heavy-duty truck axle cap includes a water storage tank 1 and a first C-shaped frame 2. A casting switching mechanism 3 is provided at the top of the water storage tank 1. The casting switching mechanism 3 includes a support pipe 301 located at the center of the top of the water storage tank 1. A rotatable turntable 302 is provided at the top of the support pipe 301. A vertical pipe 303 is installed at the center of the top of the turntable 302. A connection disk 304 is installed at the middle position on the outer side of the vertical pipe 303. A connection bearing 305 fixedly connected to the outer side of the vertical pipe 303 is installed at the inner top of the first C-shaped frame 2. A driving device 306 for driving the vertical pipe 303 to rotate is provided at the top of the first C-shaped frame 2. The driving device 306 includes a U-shaped frame 3061 located at the top of the limit disk 501. A driven gear 3062 is installed at the top end of the outer side of 303. A servo motor 3063 is installed at the top of the U-shaped frame 3061. And an output end of the servo motor 3063 is installed with a driving gear 3064 meshing with the driven gear 3062. Control the U-shaped frame 3061 to drive the driving gear 3064 to rotate. Drive the vertical pipe 303 to rotate counterclockwise by 45° each time by the transmission of the driving gear 3064 and the driven gear 3062. Then the turntable 302 and the connection disk 304 can be rotated synchronously. And the support pipe 301 will not rotate. Thus, each pair of upper casting molds 403 and lower casting molds 604 on the turntable 302 can continuously switch positions. Facilitate continuously injecting the integral axle cap housing raw material into each group of upper casting molds 403 and lower casting molds 604. Ensure that the entire forming device continuously processes and produces integral axle cap housing finished products.

[0029] As Figures 1-13As shown, an upper die mechanism 4 is arranged inside the casting switching mechanism 3 of this embodiment. An automatic lifting mechanism 5 that cooperates with the upper die mechanism 4 is arranged at the top inside the casting switching mechanism 3. The upper die mechanism 4 includes a lifting table 402. There are eight groups of lifting tables 402. First sliding rods 401 are inserted at the four corners of the eight groups of lifting tables 402. The top and bottom of the first sliding rods 401 are fixedly connected to a connecting disk 304 and a rotating disk 302 respectively. An upper casting die 403 is installed inside the lifting table 402. A first water cooling channel 404 is arranged inside the upper casting die 403. A casting inlet 405 and an exhaust port 406 are respectively arranged at the middle position of the top of the upper casting die 403. The automatic lifting mechanism 5 includes a limiting disk 501 sleeved outside a vertical pipe 303. The top of the limiting disk 501 is fixedly connected to the inner top of the first C-shaped frame 2. A U-shaped lifting rod 502 is installed at the top of the upper casting die 403. Two second sliding rods 503 are installed at the top of the U-shaped lifting rod 502. The tops of the two second sliding rods 503 extend above the connecting disk 304 and are jointly installed with a guide wheel 504 that cooperates with the limiting disk 501. A reset tension spring 505 is sleeved outside the second sliding rods 503. The top and bottom of the reset tension spring 505 are fixedly connected to the connecting disk 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 limiting disk 501. During the process of the guide wheel 504 rolling to the highest point of the edge protrusion of the limiting disk 501, the U-shaped lifting rod 502 drives the second sliding rods 503 to descend together until the upper casting die 403 and the lower casting die 604 are completely closed. The reset tension spring 505 is stretched under force. At this time, the raw material of the bridge cap integrated bridge housing is injected into the cavity between the upper casting die 403 and the lower casting die 604, and the exhaust port 406 helps to discharge the air in the cavity between the casting inlet 405, the upper casting die 403 and the lower casting die 604. During the process of the guide wheel 504 rolling to the lowest point of the edge protrusion of the limiting disk 501, the pulling force of the reset tension spring 505 pulls the upper casting die 403 to gradually separate from the lower casting die 604.

[0030] As Figures 3-6 , Figures 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 groups of 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 of the support tube 301, a turning-over assembly 606 that cooperates with the lower casting mold 604 is provided. One end of the lower casting mold 604 is installed 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 communicated with one end inside the second water cooling channel 605. The turning-over assembly 606 includes an inner ring frame 6061 at the top outside 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 formed 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 driven 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 has been 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 driven 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 product of the 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 inside the first water cooling channel 404 flowing to the second water cooling channel 605, it can play a good cooling effect on the lower casting mold 604.

[0031] As Figures 4-5 , Figures 8-9 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. At the top end inside the vertical pipe 303, a water supply component 704 for supplying water to the first water cooling channel 404 is provided. A connecting pipe 703 is installed on the outer side of the top group of horizontal pipes 701, and the output end of the connecting pipe 703 is communicated with the input end of the water supply component 704. At the bottom end inside the rotating disk 302, a water return component 706 for recovering the cooling water inside the second water cooling channel 605 is provided. The input end of the water pump 705 is communicated with the edge position at the inner bottom of the water storage bin 1, and the output end of the water pump 705 is communicated with the inside of the bottom group of horizontal pipes 701. The water supply component 704 includes a first rotary joint 7041 located at the inner top of the vertical pipe 303. The input end of the upper casting mold 403 is installed with a water supply pipe 7043 through a three-way solenoid valve 7044. The input ends of the eight groups of water supply pipes 7043 extend to the inner top of the vertical pipe 303 and are jointly installed with a first collecting bin 7042. The output end of the first rotary joint 7041 is communicated with the inner top of the first collecting bin 7042. The water return component 706 includes a second rotary joint 7061 at one end of the output pipe 603. The output end of the second rotary joint 7061 is installed with a water return pipe 7062. The output end of the water return pipe 7062 extends to the inner bottom of the vertical pipe 303 and is jointly installed with a second collecting bin 7063. A third rotary joint 7064 communicated with the inner top of the water storage bin 1 is installed at the bottom of the second collecting bin 7063. The cooling mechanism 8 includes a second C-shaped frame 801 located on the outer side of the first C-shaped frame 2. Four groups of cooling fans 802 are successively arranged from top to bottom on the outer side of the second C-shaped frame 801. A first vertical pipe 803 and a second vertical pipe 804 are respectively installed on one side of the second C-shaped frame 801, and the inside of the second vertical pipe 804 is communicated with the inside of the first vertical pipe 803.

One end of the spray pipe 805 is communicated with the inside of the first vertical pipe 803. Spray heads 806 are evenly installed on the outer sides of the second vertical pipe 804 and the spray pipes 805. A water supply pump 807 is installed at the bottom of the second C-shaped frame 801, and the input end of the water supply pump 807 is communicated with the output end of an external water pipe. The output end of the water supply pump 807 is communicated with the inner bottom of the first vertical pipe 803. Control the water pump 705 to make the cooling water inside the water storage bin 1 enter the first collecting bin 7042 successively through the horizontal pipe 701, the heat dissipation pipe 702, the connecting pipe 703 and the first rotary joint 7041, and then the cooling water enters the first water cooling channel 404 of each group of upper casting molds 403 through the water supply pipe 7043 and the three-way solenoid valve 7044, and then the cooling water passes through the second water cooling channel 605 of the lower casting mold 604. During this process, the cooling water cools the upper casting mold 403 and the lower casting mold 604.Subsequently, the cooling water then passes through the output pipe 603, the second rotary joint 7061, and the return pipe 7062 in sequence and enters the second collection bin 7063. After that, it returns to the inside of the water storage bin 1 through the third rotary joint 7064. The second rotary joint 7061 stably conveys the cooling water back to the inside of the water storage bin 1 without affecting the rotation of the lower casting mold 604, realizing the recycling of the cooling water inside the water storage bin 1. During the process of passing through the inside of the heat dissipation pipe 702, the heat dissipation effect of the cooling water can be improved. At the same time, control the water supply pump 807 to convey the external cooling water into the first vertical pipe 803, and then the spray heads 806 on the second vertical pipe 804 spray and cool the passing upper casting mold 403 and lower casting mold 604. The spray heads 806 on the water spray pipe 805 spray the surfaces of several groups of heat dissipation pipes 702. At the same time, control the cooling fan 802 to blow and cool several groups of heat dissipation pipes 702. Through the cooperation of air cooling and spray cooling, the temperature of the cooling water after passing through the heat dissipation pipe 702 can be quickly reduced, thereby ensuring the subsequent cooling effect of the cooling water on the upper casting mold 403 and the lower casting mold 604.,

[0032] Such as Figures 9-11As shown in the figure, the first water cooling channel 404 of this embodiment includes first U-shaped through grooves 4041 located at both ends inside the upper casting mold 403, and a plurality of groups of first connecting through grooves 4042 are interconnected between the two groups of first U-shaped through grooves 4041. The plurality of groups of first connecting through grooves 4042 are evenly distributed on both sides inside the upper casting mold 403. One end of the top of the upper casting mold 403 is provided with a water inlet joint 4043 communicating with the inside of an adjacent group of first U-shaped through grooves 4041. One end of the bottom of the upper casting mold 403 away from the water inlet joint 4043 is provided with a connection socket 4044 communicating with the inside of the other group of first U-shaped through grooves 4041. The top end of the water inlet joint 4043 is communicated with the output end of the three-way solenoid valve 7044. The second water cooling channel 605 includes second U-shaped through grooves 6051 located at both ends inside the lower casting mold 604, and a plurality of groups of second connecting through grooves 6052 are interconnected between the two groups of second U-shaped through grooves 6051. One end of the top of the lower casting mold 604 away from the output pipe 603 is provided with a connection plug 6053 that cooperates with the connection socket 4044, and the connection plug 6053 is communicated with the inside of an adjacent group of second U-shaped through grooves 6051. After the cooling water is transported into the inside of a group of first U-shaped through grooves 4041 by the water supply pipe 7043 through the three-way solenoid valve 7044, the cooling water flows into another group of first connecting through grooves 4042 through the first connecting through grooves 4042. Then, the cooling water enters a group of second U-shaped through grooves 6051 through the connection socket 4044 and the connection plug 6053. Subsequently, the cooling water enters the second group of second U-shaped through grooves 6051 through the second connecting through grooves 6052. Then, the cooling water enters the return pipe 7062 through the output pipe 603 and the second rotary joint 7061. During this process, the cooling water can cool down the upper casting mold 403 and the lower casting mold 604, thereby helping the bridge cap integral bridge shell in the cavity between the upper casting mold 403 and the lower casting mold 604 to be quickly cooled and formed.

[0033] As Figures 1-5 shown, a protective shell 9 covering the limiting disk 501 is installed on the top of the connecting disk 304 of this embodiment. A material guiding hopper 10 is installed on the top outside the support pipe 301, and the material guiding hopper 10 is located directly below the fan-shaped notch 6065. The protective shell 9 can completely cover some structures of the automatic lifting mechanism 5 above the connecting disk 304, which is not only beautiful but also can prevent foreign objects from accidentally entering the top of the connecting disk 304 and affecting the normal lifting of the lifting table 402. When a pair of upper casting mold 403 and lower casting mold 604 rotate to directly above the material guiding hopper 10, the lower casting mold 604 will automatically turn over to discharge the bridge cap integral bridge shell formed inside the lower casting mold 604, and the material guiding hopper 10 can catch the falling bridge cap integral bridge shell and guide it into the bin specifically used for collecting the bridge cap integral bridge shell.

[0034] As Figures 15-16 andFigure 18 As shown, 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, and the output end of the drainage hose is communicated with an external collection pool, while the input end of the drainage hose is communicated with 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.

[0035] The working principle of this embodiment is as follows. The position of a group of square through-holes 601 directly opposite the first C-shaped frame 2 is set as the first processing position. First, the material for casting the bridge cap integral bridge housing is injected into the casting inlet 405 at the first working position. The raw material of the bridge cap integral bridge housing enters the casting cavity formed by the upper casting mold 403 and the lower casting mold 604. After the group of casting cavities is filled with the raw material of the bridge cap integral bridge housing, the servo motor 3063 is controlled to drive the rotating disk 302 to rotate counterclockwise by 45° each time, so that each subsequent pair of upper casting mold 403 and lower casting mold 604 passes through the first processing position in turn. After each pair of upper casting mold 403 and lower casting mold 604 leaves the first processing position, the water pump 705 is controlled to pump the cooling water in the water storage tank 1 into the first collecting bin 7042 in turn through the horizontal pipe 701, the heat dissipation pipe 702, the connecting pipe 703 and the first rotary joint 7041, and then is transported to the first water cooling channel 404 of each group of upper casting molds 403 through the water supply pipe 7043 and the three-way solenoid valve 7044. Then the cooling water enters the second water cooling channel 605 of the lower casting mold 604. During this process, the cooling water cools the upper casting mold 403 and the lower casting mold 604. Subsequently, the cooling water returns to the inside of the water storage tank 1 in turn through the output pipe 603, the second rotary joint 7061, the return pipe 7062, the second collecting bin 7063 and the third rotary joint 7064. During the counterclockwise rotation of the rotating disk 302, each pair of upper casting mold 403 and lower casting mold 604 is first in the closed mold state and then gradually separates. During the process that the lower casting mold 604 passes above the fan-shaped notch 6065, this group of lower casting molds 604 is turned over with the casting groove facing downwards due to the cooperation of the arc-shaped rack 6062 and the passive gear 6066, and the cast bridge cap integral bridge housing is discharged. Then this group of lower casting molds 604 is rotated again with the casting groove facing upwards. Subsequently, when this group of lower casting molds 604 continues to rotate around the support pipe 301 as the axis, its bottom will always slide on a plurality of guide rollers 6064. During the process of casting the bridge cap integral bridge housing by 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 the spray heads 806 on the second vertical pipe 804 spray and cool the passing upper casting mold 403 and lower casting mold 604, while the spray heads 806 on the water spray pipe 805 spray the surfaces of a plurality of heat dissipation pipes 702. At the same time, the cooling fan 802 is controlled to blow and cool a plurality of heat dissipation pipes 702. Whenever the upper casting mold 403 and the lower casting mold 604 are about to separate, the three-way solenoid valve 7044 on this group of upper casting molds 403 is controlled to close the continuous water supply of the water supply pipe 7043 and open another interface to allow external air to enter the first water cooling channel 404 and the second water cooling channel 605, so that all the cooling water inside the first water cooling channel 404 and the second water cooling channel 605 returns to the inside 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, open the water supply end of the three-way solenoid valve 7044 and close the air inlet end.

[0036] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
