Description

Technical Field

[0001] The invention relates to the technical field of flange production, in particular to a die-casting device for flange production. Background Art

[0002] As a key component for connecting mechanical equipment, containers and pipelines, flanges play an indispensable role in many fields. In the field of automobile manufacturing, many parts such as engines, transmissions and chassis rely on flanges for connection. Taking the intake and exhaust systems of engines as an example, the die-cast flanges bear the important task of connecting pipelines and engine cylinders, ensuring that gas can be transmitted in a sealed manner, thereby ensuring the efficient and stable operation of the engine. When processing flanges, the manufacturing process is usually die-casting. The specific process is to pour the molten metal into the inner cavity of the die-casting mold, and then form it after the molten metal is cooled. In order to allow the molten metal to cool and form quickly, a cooling pipe is generally provided around the surface of the mold, and then the coolant is connected to the cooling pipe. The continuously flowing coolant will continuously take away the heat from the surface of the mold as the cooling pipe fits the mold, thereby quickly achieving the cooling effect. For example, the Chinese patent with publication number CN111318670A is a die-casting molding device for flange production; When processing flanges and cooling molten metal, the above-mentioned die-casting device can only complete the processing of a single flange in one operation. In the entire production process, from pouring molten metal to cooling and forming, all can only be performed sequentially for one flange, and it is difficult to realize the simultaneous processing of multiple flanges. This leads to low production efficiency and consumes a lot of time and cost. It is not suitable for mass production scenarios of flanges that require large-scale output, and cannot meet the huge demand for the number of flanges in industries such as automobile manufacturing.

The inner wall of the slider is slidably connected to the surface of the sliding column.

[0008] As a further improvement of this technical solution, a feed inlet is formed in the top of the upper mold, and an inlet component is arranged on the inner wall of the feed inlet.

[0009] As a further improvement of this technical solution, the inlet component includes a feed pipe fixedly connected to the inner wall of the feed inlet. There are four feed pipes, and the four feed pipes are divided into two groups. A small connecting pipe is slidably connected to the surface of one group of feed pipes. There are two small connecting pipes, which are divided into two groups.

The ends of the two groups of small connecting pipes are fixedly connected to a large connecting pipe. The end of the large connecting pipe is fixedly connected to a feed frame. An annular bracket is fixedly connected to the surface of the feed frame, and the bottom of the annular bracket is fixedly connected to the top of the bracket.

[0010] As a further improvement of this technical solution, a limiting frame is fixedly connected to the surface of the small connecting pipe, and a chute is formed in the inner wall of the limiting frame. A sliding plate is fixedly connected to the surface of the feed pipe, and the surface of the sliding plate is slidably connected to the inner wall of the chute.

[0011] As a further improvement of the technical solution, the annular cooling assembly includes an annular cooling pipe fixedly connected to the surface of the lower mold.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the die-casting forming device for flange production, by arranging multiple sets of upper molds and lower molds, and fixedly connecting the connecting steel plate to the bottom of the upper mold. At this time, when the hydraulic device works, it can drive the connecting steel plate to move downward, so as to drive the upper molds in multiple sets of mold components at the same time, realizing the simultaneous operation of multiple sets of molds, greatly improving the production efficiency. And the central positions of the lower mold and the upper mold are on the same vertical line.

When the upper mold drives the feed pipe to move downward, the sliding plate slides along the sliding groove, ensuring both the stability and guiding property of the movement of the feed pipe and maintaining the relative movement state between the feed pipe and the small connecting pipe. Even during the movement of the mold components driven by the connecting steel plate, the smoothness of the molten metal transportation path can be guaranteed.

[0015] 3. In the die-casting forming device for flange production, by surrounding the annular cooling pipe around the lower mold and surrounding the connecting cooling pipe around the surface of another lower mold, the two work together. By the surrounding method, it can closely fit the lower mold over a large area, effectively absorbing the heat dissipated by the molten metal in the inner cavity of the lower mold, efficiently cooling the molten metal in the lower mold and the upper mold, and ensuring that the molten metal can quickly solidify and form; Two sets of cooling units composed of annular cooling pipes, first transfer pipes, and connecting cooling pipes are interconnected through the transfer pipes to form a circulation path for the coolant. One set of cooling units receives the coolant through the liquid inlet pipe, and the other set discharges the coolant through the liquid discharge pipe, enabling the coolant to continuously cool multiple lower molds.

Detailed Embodiment

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0019] Please refer to Figures 1-9 As shown in the figure, this embodiment provides a die-casting forming device for flange production, including a workbench main body 100. A bracket 110 is fixedly connected to the top of the workbench main body 100. A hydraulic device 120 is fixedly connected to the top of the bracket 110. A synchronous moving component 200 is arranged at the output end of the hydraulic device 120 through the inner wall of the bracket 110. A die set component 300 is arranged on the inner wall of the workbench main body 100; The die set component 300 is composed of multiple groups of upper dies and lower dies. The bottom of the synchronous moving component 200 contacts the top of the die set component 300. The synchronous moving component 200 drives multiple groups of upper dies to move downward simultaneously and connect with the corresponding lower dies below; An feeding component 400 is arranged on the inner wall of the die set component 300, which is used to feed materials into multiple groups of dies simultaneously, and cooperate with the synchronous moving component 200 to drive the die set component 300 to move downward, so that the molten metal fills the inner cavity of the die set component 300; An annular cooling component 500 surrounds the surface of the die set component 300, and the annular cooling component 500 is interconnected, which is used to cool down multiple groups of die set components 300 simultaneously; When the hydraulic device 120 starts to operate, the hydraulic power it generates drives the connected synchronous moving component 200 to move downward. The synchronous moving component 200 is connected to the upper molds in multiple mold components 300, so it can drive these upper molds to move downward synchronously until the upper molds are docked with the lower molds in the mold components 300 to form a closed mold cavity. At this time, the feeding component 400 located on the inner wall of the mold component 300 where the synchronous moving component 200 is located uses its connection with multiple sets of molds to transport the molten metal liquid into each mold cavity. After the metal liquid filling is completed, the hydraulic device 120 continues to maintain its working state and continuously outputs hydraulic power to further drive the synchronous moving component 200 to move downward. This action causes the upper molds in the mold component 300 to continue to move downward, enabling the metal liquid in the inner cavity of the mold component 300 to fully fill and closely fit each part of the mold cavity under pressure, ensuring that the metal liquid is evenly distributed and the internal structure is compacted. Finally, the annular cooling component 500 distributed on the surface of the mold component 300, arranged in a circular array and interconnected, starts to play a cooling role and cools multiple mold components 300 simultaneously, prompting the metal liquid in the mold cavity to quickly cool and solidify, completing the die-casting forming process of the flange.

[0020] Considering that this die-casting device can only complete the processing of a single flange in one operation during the processing of the flange and the cooling of the metal liquid, in the entire production process, from the pouring of the metal liquid to the cooling and forming, it can only be carried out sequentially for one flange, and it is difficult to process multiple flanges simultaneously. This results in low production efficiency, consumes a large amount of time costs, and is not suitable for the mass production scenario of flanges that require large-scale output, and cannot meet the huge demand for the number of flanges in industries such as automobile manufacturing. Therefore, by driving multiple upper molds to act simultaneously through the synchronous moving component 200, the feeding component 400 can transport the metal liquid to multiple mold cavities at the same time, and the annular cooling component 500 can cool multiple molds simultaneously, realizing the parallel production of multiple flanges. Compared with the device that can only process a single flange at a time, the production cycle is greatly shortened, and the output per unit time is significantly increased.

[0021] Meanwhile, considering that the upper die in the die assembly 300 will move downward under the drive of the synchronous moving assembly 200, at this time, the feeding assembly 400 will gradually separate from the die assembly 300, affecting the feeding of molten metal into the die assembly 300 by the feeding assembly 400. Therefore, when the die assembly 300 moves downward under the drive of the synchronous moving assembly 200, the connected feeding assembly 400 will move downward synchronously. At this time, during the entire process of the upper die in the die assembly 300 continuing to move downward until it docks with the lower die to complete the die closing, the feeding assembly 400 can always maintain a stable connection state with the die assembly 300, ensuring that the feeding assembly 400 can smoothly transport the molten metal into each die cavity and successfully complete the filling of the molten metal.

[0022] On the above basis, the specific structure is disclosed in detail: In order to enable the synchronous moving assembly 200 to simultaneously drive the upper dies in multiple groups of die assemblies 300 to move downward, it is necessary to further disclose the parts of the synchronous moving assembly 200. Therefore, the synchronous moving assembly 200 includes a connecting steel plate 210 fixedly connected to the output end of the hydraulic device 120, and the bottom of the connecting steel plate 210 is provided with a die assembly 300; The connecting steel plate 210 is located below the bracket 110. When the hydraulic device 120 works, it will drive the connecting steel plate 210 to move downward. During the downward movement of the connecting steel plate 210, it will drive the die assembly 300 to move downward.

[0023] In order to enable the die assembly 300 to cooperate with the connecting steel plate 210 to move downward and connect the upper die and the lower die therein, it is necessary to further disclose the parts of the die assembly 300. Therefore, the die assembly 300 includes multiple groups of upper dies 320 fixedly connected to the bottom of the connecting steel plate 210. Multiple fixing grooves 1001 are opened at the top of the workbench main body 100, and the inner walls of the multiple fixing grooves 1001 are fixedly connected with lower dies 310. The inner wall of the lower die 310 is slidably connected with a jacking rod 3101; The center position at the top of the lower die 310 and the center position at the bottom of the upper die 320 are on the same vertical line; when the connecting steel plate 210 moves downward, it can drive the upper die 320 to gradually approach and fit with the lower die 310. When the feeding assembly 400 transports the molten metal into the inner cavities of the lower die 310 and the upper die 320, at this time, the hydraulic device 120 continues to work to drive the upper die 320 to continue to move downward, so that under the action of pressure, the molten metal can fully fill and closely fit each part of the die cavity, ensuring that the molten metal is evenly distributed and the internal structure is compacted.

[0024] Considering that when the connecting steel plate 210 moves downward, in order to keep the moving trajectory vertically downward and avoid the misalignment between the lower die 310 and the upper die 320, a sliding column 220 is fixedly connected to the bottom of the connecting steel plate 210, and a sliding block 230 is fixedly connected to the inner wall of the workbench main body 100; The inner wall of the sliding block 230 is slidably connected to the surface of the sliding column 220. When the connecting steel plate 210 moves downward, the surface of the sliding column 220 slides on the inner wall of the sliding block 230, restricting the downward movement trajectory of the connecting steel plate 210 and avoiding the deviation between the lower die 310 and the upper die 320.

[0025] In order to enable the molten metal in the feeding assembly 400 to flow smoothly into the inner cavity of the die assembly 300, a feeding port 3201 is opened at the top of the upper die 320, and the feeding assembly 400 is arranged on the inner wall of the feeding port 3201. By opening the feeding port 3201 at the top of the upper die 320, the molten metal in the feeding assembly 400 can flow smoothly into the space between the lower die 310 and the upper die 320 through the feeding port 3201.

[0026] In order to enable the coolant in the feeding assembly 400 to flow smoothly between the lower die 310 and the upper die 320, the parts of the feeding assembly 400 need to be further disclosed. Therefore, the feeding assembly 400 includes a feeding pipe 410 fixedly connected to the inner wall of the feeding port 3201. There are four feeding pipes 410, and the four feeding pipes 410 are grouped in pairs. A small connecting pipe 420 is slidably connected to the surface of one group of feeding pipes 410; There are two small connecting pipes 420, which are divided into two groups. Each group of small connecting pipes 420 is slidably connected to one group of feeding pipes 410, and at the same time, each group of small connecting pipes 420 communicates with the corresponding group of feeding pipes 410; The ends of the two groups of small connecting pipes 420 are fixedly connected to a large connecting pipe 440. The end of the large connecting pipe 440 is fixedly connected to a feeding frame 450. A circular bracket 460 is fixedly connected to the surface of the feeding frame 450. The bottom of the circular bracket 460 is fixedly connected to the top of the bracket 110. First, the processed and melted molten metal is injected into the feeding frame 450. Then, under the action of gravity, the molten metal flows into the large connecting pipe 440 fixedly connected to it. The molten metal in the large connecting pipe 440 is further divided into the two groups of small connecting pipes 420 connected to it. Since each group of small connecting pipes 420 is both slidably connected to and communicates with one group of feeding pipes 410, the molten metal can continue to be divided from each group of small connecting pipes 420 into the corresponding feeding pipes 410. And because the feeding pipes 410 are fixedly arranged on the inner wall of the feeding port 3201, the feeding port 3201 can receive the molten metal from the feeding pipes 410, thus completing the conveying process of the molten metal in the feeding assembly 400.

[0027] In order to enable the feed pipe 410 and the small connecting pipe 420 to be slidably connected when the connecting steel plate 210 drives the lower die 310 to move downward, a limiting frame 430 is fixedly connected to the surface of the small connecting pipe 420, and a sliding groove 4301 is provided in the inner wall of the limiting frame 430; A sliding plate 4101 is fixedly connected to the surface of the feed pipe 410, and the surface of the sliding plate 4101 is slidably connected to the inner wall of the sliding groove 4301. When the upper die 320 moves downward, it will drive the feed pipe 410 to move downward at the same time. The sliding plate 4101 provided on the feed pipe 410 will slide along the inner wall of the sliding groove 4301, so as to ensure the stability and guiding property of the movement of the feed pipe 410. At this time, the surface of the feed pipe 410 slides in the inner wall of the small connecting pipe 420, so that a relative movement state is maintained between the feed pipe 410 and the small connecting pipe 420, ensuring the smoothness of the metal liquid conveying path during the movement of the feed pipe 410.

[0028] In order to enable the annular cooling assembly 500 to cool the metal liquid in the lower die 310 and the upper die 320, it is necessary to further disclose the parts of the annular cooling assembly 500. Therefore, the annular cooling assembly 500 includes an annular cooling pipe 510 fixedly connected to the surface of the lower die 310. A liquid inlet pipe 5101 is fixedly connected to the end of the annular cooling pipe 510. A first transmission pipe 520 is fixedly connected and communicated to the end of the annular cooling pipe 510 far away from the liquid inlet pipe 5101. A connecting cooling pipe 530 is fixedly connected and communicated to the end of the first transmission pipe 520 far away from the annular cooling pipe 510. A transmission pipe 540 is fixedly connected and communicated to the end of the connecting cooling pipe 530 far away from the first transmission pipe 520; A liquid discharge pipe 550 is fixedly connected to the end of the connecting cooling pipe 530 far away from the first transmission pipe 520; The annular cooling pipe 510, the first transmission pipe 520 and the connecting cooling pipe 530 together form a set of cooling units, a total of two sets. The annular cooling pipe 510 in one set is connected and communicated with an external cooling device through the liquid inlet pipe 5101 for receiving coolant. The connecting cooling pipe 530 in the other set is used to discharge the coolant through the liquid discharge pipe 550. And the two sets of cooling units are interconnected through the transmission pipe 540 to form a circulation path of the coolant. Among them, the annular cooling pipe 510 and the connecting cooling pipe 530 are both wound around the surface of different lower dies 310, and their functions are the same. Then the first transmission pipe 520 circulates the coolant in the cooling pipe 510 into the connecting cooling pipe 530; Connect the liquid inlet pipe 5101 to the cooling device. When the cooling device starts to work, the coolant is conveyed into the liquid inlet pipe 5101 and flows into the annular cooling pipe 510 through the liquid inlet pipe 5101. Since the annular cooling pipe 510 is annularly distributed around the surface of the lower mold 310, it can effectively absorb the heat dissipated from the inner cavity of the lower mold 310. As the cooling device continues to operate, the coolant in the annular cooling pipe 510 flows into the first transmission pipe 520 and the connecting cooling pipe 530 connected thereto in sequence, and then enters the transmission pipe 540. The transmission pipe 540 serves as a connection channel between the two groups of cooling pipes, enabling the coolant to enter the other group of cooling pipes through the transmission pipe 540. The coolant entering the other group of cooling pipes repeats the above flow process and finally flows out from the drain pipe 550, thereby realizing the circulating flow of the coolant in the annular cooling assembly 500 and continuously cooling the lower mold 310.

[0029] A pipe fixing groove 1002 is formed at the bottom of the workbench main body 100, and the first transmission pipe 520 is arranged on the inner wall of the pipe fixing groove 1002. The annular cooling pipe 510 is located in the inner cavity of the fixing groove 1001. By providing the fixing groove 1001 and the pipe fixing groove 1002, the annular cooling pipe 510 and the first transmission pipe 520 can be arranged around the surface of the lower mold 310.

[0030] In summary, the working process of the present invention is as follows: First, start the hydraulic device 120 to work. The hydraulic power generated by it drives the connected connecting steel plate 210 to move downward. By the downward movement of the connecting steel plate 210, the upper die 320 can be gradually brought closer to the lower die 310. At this time, the surface of the sliding column 220 slides inside the inner wall of the slider 230, restricting the downward movement trajectory of the connecting steel plate 210 to prevent the lower die 310 and the upper die 320 from shifting. Until the lower die 310 and the upper die 320 are in contact. At this time, the melted metal liquid is injected into the feeding frame 450. Then, under the action of gravity, the metal liquid flows into the large connecting pipe 440 fixedly connected to it. The metal liquid in the large connecting pipe 440 is further divided into two groups of small connecting pipes 420 connected to it. Since each group of small connecting pipes 420 is both slidably connected and interconnected with a group of feeding pipes 410, the metal liquid can continue to be divided from each group of small connecting pipes 420 to the corresponding feeding pipes 410. And because the feeding pipes 410 are fixedly connected to the inner wall of the feeding port 3201, the feeding port 3201 can receive the metal liquid from the feeding pipes 410. At this time, the metal liquid will be filled between the lower die 310 and the upper die 320. At this time, the hydraulic device 120 will continue to work to drive the upper die 320 to move downward continuously, so that the metal liquid can be fully filled and closely attached to each part of the mold cavity under the action of pressure. Then, connect the liquid inlet pipe 5101 to the cooling device. When the cooling device starts to work, the coolant is transported into the liquid inlet pipe 5101 and flows into the annular cooling pipe 510 through the liquid inlet pipe 5101. Since the annular cooling pipe 510 is annularly distributed around the surface of the lower die 310, it can effectively absorb the heat dissipated from the inner cavity of the lower die 310. As the cooling device continues to operate, the coolant in the annular cooling pipe 510 flows into the first transmission pipe 520 and the connecting cooling pipe 530 connected to it in sequence, and then enters the transmission pipe 540. The transmission pipe 540 serves as a connection channel between the two groups of cooling pipes, enabling the coolant to enter the other group of cooling pipes through the transmission pipe 540. The coolant entering the other group of cooling pipes repeats the above flow process and finally flows out from the drain pipe 550, thereby realizing the circulating flow of the coolant in the annular cooling assembly 500 and continuously cooling the lower die 310.
