Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy shell casting, and more specifically, to a battery pack aluminum alloy shell casting device. Background Art

[0002] A battery pack is an integrated device composed of multiple battery cells, used to store and provide electrical energy. A battery pack is usually composed of multiple battery cells (such as lithium-ion batteries, nickel-metal hydride batteries, etc.) connected together in a certain combination, and is equipped with management systems, protection circuits, shells and other components to form a complete battery assembly structure. The battery pack shell is an important part of protecting the internal components of the battery.

[0003] Battery pack shell materials are generally made of lightweight and strong materials such as plastic and aluminum alloy. The current battery pack shell is mainly made of aluminum alloy shell and is cast.

[0004] Because the battery pack shell is thin and the shape and structure of some shells are complex, the space of the casting cavity is relatively small and the size distribution is uneven. During the liquid flow process, uneven flow is likely to occur, especially at the corners. If there are many corners, shrinkage holes or looseness will occur, affecting the casting quality. In addition, during the casting process, if the gas in the mold is not completely discharged, pores will be formed in the final product, affecting the sealing and strength of the battery shell. Summary of the invention

[0015] Technical effects and advantages of the present invention:

[0016] 1. In the process of the aluminum alloy solution of the present invention entering between the movable mold and the fixed mold through the feed port, the movable mold and the fixed mold rotate. Under the action of centrifugal force, the aluminum alloy solution will quickly fill the edges of the movable mold and the fixed mold, so that the aluminum alloy solution can flow in fully, avoiding shrinkage holes or looseness. At the same time, it is avoided that the aluminum alloy solution solidifies prematurely due to slow flow due to the flatness between the movable mold and the fixed mold, and the insufficient fluidity of the aluminum alloy solution causes the gas to be trapped inside the metal, thereby forming bubbles and pores, which affect the sealing and strength of the battery shell.

[0017] 2. The aluminum alloy solution of the present invention flows out from the discharge pipe through the discharge channel and the discharge trough. The arc surface of the discharge trough is used to slow down the aluminum alloy solution when it enters the movable mold and the fixed mold. Due to the effect of gravity, it impacts and splashes, thereby resulting in more absorbed gas, thereby preventing these gases from forming bubbles when the battery pack shell is cooled and solidified.

[0018] 3. The present invention arranges the rotating disk to rotate, so that the pad rotates. Under the action of the return spring, the ball hits the bottom of the rotating disk, thereby quickly breaking and discharging the bubbles inside the aluminum alloy solution, preventing the bubbles from affecting the casting quality of the aluminum alloy shell, and improving the sealing and strength of the battery shell.

[0019] 4. In the present invention, under the action of the lifting cylinder, the heat-insulating crucible descends, and the fixed cover is sleeved on the outer surface of the feed port to prevent the aluminum alloy solution from splashing and leaking.

[0020] 5. Before the casting process of the battery pack shell, the present invention preheats the inner wall of the second mold by means of a heating plate, so as to prevent the aluminum alloy solution from coming into contact with the cooled movable mold and fixed mold when entering the movable mold and the fixed mold, causing premature solidification, resulting in insufficient fluidity of the aluminum alloy solution, and being unable to fill the edges of the movable mold and the fixed mold, thus affecting the casting quality of the battery pack shell.

[0021] 6. After the battery pack shell is cast, the semiconductor refrigeration plate of the present invention works to quickly cool the inner wall of the first mold, and the heat exchanged by the semiconductor refrigeration plate is accumulated inside the inner cavity. Through the operation of the fan assembly, the air quickly passes through the interior of the inner cavity and is discharged from the exhaust port, thereby achieving rapid cooling of the fixed mold and improving the cooling efficiency of the casting equipment.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] First embodiment

[0034] As attached Figure 1 To Attachment Figure 3 As an embodiment of the present invention, the movable mold 3 moves to the side of the fixed mold 4 and contacts it. Through the injection assembly 2, the aluminum alloy solution enters between the movable mold 3 and the fixed mold 4 through the feed port 42. The rotating motor 18 controls the rotating disk 13 to rotate inside the support frame 12, thereby rotating the movable mold 3 and the fixed mold 4. Under the action of centrifugal force, the aluminum alloy solution will quickly fill the edges of the movable mold 3 and the fixed mold 4, so that the aluminum alloy solution can fully flow in to avoid shrinkage holes or looseness. At the same time, it is prevented that the aluminum alloy solution due to the flatness between the movable mold 3 and the fixed mold 4 causes the aluminum alloy solution to solidify prematurely due to slow flow, and the insufficient fluidity of the aluminum alloy solution causes the gas to be trapped inside the metal, thereby forming bubbles and pores, which affect the sealing and strength of the battery shell.

[0035] A battery pack aluminum alloy shell casting device comprises a casting workbench 1, a material injection assembly 2 is fixedly installed on the right side of the top of the casting workbench 1, a fixed mold 4 is arranged on the top of the casting workbench 1, and a movable mold 3 is movably installed on one side of the fixed mold 4;

[0036] The casting workbench 1 includes a fixed table 11, a support frame 12 is fixedly installed on the top of the fixed table 11, a rotating disk 13 is rotatably installed inside the support frame 12, guide frames 14 are fixedly installed on both sides of the top of the rotating disk 13, a moving motor 15 is fixedly installed on the top of the rotating disk 13, a rotating screw 16 is fixedly installed on one side of the moving motor 15, and the rotating screw 16 is rotatably installed inside the guide frame 14, a base plate 17 is fixedly installed on the bottom of the fixed table 11, a rotating motor 18 is fixedly installed on the top of the base plate 17, and the rotating motor 18 is fixedly connected to the bottom of the rotating disk 13 through a rotating shaft.

[0037] In this embodiment, the moving motor 15 controls the rotating screw 16 to rotate, so that the moving mold 3 moves along the guide frame 14 and fits against the side of the fixed mold 4. Through the injection assembly 2, the aluminum alloy solution enters between the moving mold 3 and the fixed mold 4 through the feed port 42. The rotating motor 18 controls the rotating disk 13 to rotate inside the support frame 12. After the casting is completed, the rotation of the rotating disk 13 is stopped, and the moving mold 3 moves out of the side of the fixed mold 4 to unload the cast aluminum alloy shell.

[0038] Second embodiment

[0039] As attached Figure 1 To Attachment Figure 4 , attached Figure 8 To Attachment Fig. 9 This is an embodiment of the present invention. On the basis of the first embodiment, in order to further prevent the aluminum alloy solution from absorbing too much gas (such as oxygen and nitrogen) in the air during the process of entering between the movable mold 3 and the fixed mold 4 through the feed port 42, thereby generating more bubbles, before the aluminum alloy solution enters the movable mold 3 and the fixed mold 4, the aluminum alloy solution flows out from the discharge pipe 212 through the discharge channel 29, and flows out through the discharge trough 211. The arc surface of the discharge trough 211 is used to slow down the aluminum alloy solution when entering the movable mold 3 and the fixed mold 4. Due to the effect of gravity, the impact causes splashing, thereby resulting in more absorbed gas. In the casting process, the rotating disk 13 is rotated to rotate the pad 110. Under the action of the return spring 112, the ball 114 knocks on the bottom of the rotating disk 13, thereby quickly breaking and discharging the bubbles inside the aluminum alloy solution, preventing the bubbles from affecting the casting quality of the aluminum alloy shell, and improving the sealing and strength of the battery shell.

[0040] As attached Figure 4As shown, four pads 110 are fixedly installed at the bottom of the rotating disk 13, and one end of the pad 110 is higher than the other end of the pad 110, and eight fixed sleeves 111 are fixedly installed on the top of the fixed platform 11 below the rotating disk 13, and the eight fixed sleeves 111 are distributed in a circle on the top of the fixed platform 11, and a movable block 113 is movably sleeved inside the fixed sleeve 111, and a return spring 112 is arranged between the inside of the fixed sleeve 111 and the movable block 113, and a ball 114 is rotatably installed on the top of the movable block 113, and the ball 114 rolls on the bottom of the rotating disk 13 and the pad 110.

[0041] In this embodiment, the rotating disk 13 rotates under the action of the rotating motor 18, and the pad 110 at the bottom of the rotating disk 13 will rotate in a circle with the rotation of the rotating disk 13. Since one end of the pad 110 is higher than the other end, the ball 114 first passes through the lower end of the pad 110, and as the pad 110 rotates, the ball 114 and the movable block 113 are gradually squeezed to compress the return spring 112. After passing through the pad 110, the reaction force of the return spring 112 is used to make the ball 114 knock on the bottom of the rotating disk 13, causing the movable mold 3 and the fixed mold 4 to vibrate, thereby breaking the aluminum alloy solution and discharging it.

[0042] As attached Figure 8 To Attachment Fig. 9 As shown, the injection assembly 2 includes a fixed frame 21, a heat-insulating crucible 22 is arranged on the top of the fixed frame 21, a feed cover 23 is arranged on the top of the heat-insulating crucible 22, a feed pipe 24 is fixedly connected to the bottom of the heat-insulating crucible 22, a solenoid valve 28 is arranged on one side of the feed pipe 24, and a fixed cover 25 is fixedly sleeved on the outer surface of the lower end of the feed pipe 24, which is sleeved on the outer surface of the feed port 42 through the fixed cover 25 to prevent the aluminum alloy solution from splashing and to prevent the aluminum alloy solution from leaking.

[0043] As attached Fig. 9 As shown, a feeding channel 29 is provided at the upper end of the feeding tube 24, and a discharge pipe 212 is fixedly connected to the inside of the lower end of the feeding tube 24. The feeding channel 29 is connected to the discharge pipe 212, and a discharge nozzle 26 is fixedly installed at the bottom of the discharge pipe 212. An exhaust channel 210 is formed between the feeding tube 24 and the discharge pipe 212. The length of the bottom of the discharge pipe 212 is longer than the length of the bottom of the feeding tube 24. A plurality of discharge grooves 211 are provided at the upper end of the discharge nozzle 26, and the plurality of discharge grooves 211 are connected to the discharge pipe 212. The outer shape of the discharge grooves 211 is arc-shaped. A plurality of exhaust holes 27 are provided at the upper end of the exhaust channel 210, and the exhaust holes 27 are located above the fixed cover 25 and are connected to the exhaust channel 210.

[0044] Among them, the fixed cover 25 is movably sleeved on the outer surface of the feed port 42, the discharge nozzle 26 is movably sleeved inside the feed port 42, the two ends of the bottom of the fixed frame 21 are fixedly installed with lifting cylinders 214, the outer surface of the insulating crucible 22 is fixedly sleeved with a fixed ring 213, and the tops of the two lifting cylinders 214 are connected to the two ends of the fixed ring 213.

[0045] In this embodiment, under the action of the lifting cylinder 214, the insulation crucible 22 descends, and the fixed cover 25 is sleeved on the outer surface of the feed port 42, and the solenoid valve 28 is opened, so that the aluminum alloy solution passes through the insulation crucible 22, and is discharged from the discharge channel 29 through the discharge pipe 212 and the discharge trough 211. The arc surface of the discharge trough 211 slows down the splashing caused by the flow of the aluminum alloy solution, thereby reducing the absorption of gas in the air. As the aluminum alloy solution is injected, the gas inside the movable mold 3 and the fixed mold 4 passes through the exhaust channel 210 and is discharged from the exhaust hole 27.

[0046] Third embodiment

[0047] As attached Figure 1 To Attachment Figure 7 As one embodiment of the present invention, a heating plate 32 is provided on one side of the second mold 31. Before the casting process of the battery pack shell, the inner wall of the second mold 31 is preheated by the heating plate 32 to prevent the aluminum alloy solution from coming into contact with the cooled movable mold 3 and the fixed mold 4 when entering the movable mold 3 and the fixed mold 4, thereby preventing the aluminum alloy solution from solidifying prematurely, resulting in insufficient fluidity of the aluminum alloy solution and being unable to fill the edges of the movable mold 3 and the fixed mold 4, thereby affecting the casting quality of the battery pack shell.

[0048] As attached Figure 6 As shown, the fixed mold 4 includes a first mold 41, which is fixedly installed in the middle of the top of the rotating disk 13, a feed port 42 is arranged on the top of the first mold 41, an inner cavity 43 is opened inside the first mold 41, an exhaust port 44 is opened on the top of the first mold 41, the inner cavity 43 is communicated with the exhaust port 44, a semiconductor cooling plate 45 is fixedly installed on the left side of the first mold 41, an air inlet 46 is fixedly installed on the right side below the first mold 41, and a fan assembly 47 is fixedly installed inside the air inlet 46.

[0049] The first mold 41 is fixedly mounted on one side of the guide frame 14 , the moving motor 15 is fixedly mounted on one side of the bottom of the first mold 41 , and the rotating screw 16 is rotatably mounted inside the lower end of the first mold 41 .

[0050] In this embodiment, after the battery pack shell is cast, the semiconductor refrigeration sheet 45 works to quickly cool the inner wall of the first mold 41, and the heat exchanged by the semiconductor refrigeration sheet 45 is accumulated inside the inner cavity 43. Through the operation of the fan assembly 47, the air quickly passes through the interior of the inner cavity 43 and is discharged from the exhaust port 44, thereby achieving rapid cooling of the fixed mold 4.

[0051] Among them, the movable mold 3 includes a second mold 31, and a heating plate 32 is fixedly installed on the side of the second mold 31 away from the first mold 41. The four corners of the second mold 31 are provided with socket holes 33, and the socket holes 33 are movably socketed on the outer surface of the guide frame 14. The lower end of the second mold 31 is provided with a threaded hole 34, and the threaded hole 34 is threadedly installed on the outer surface of the rotating screw 16.

[0052] In this embodiment, since the aluminum alloy shell of the battery pack is relatively thin, a heating plate 32 is provided on the side of the movable mold 3, and a semiconductor cooling plate 45 is provided on the side of the first mold 41, so as to quickly heat and cool the aluminum alloy shell of the battery pack.

[0053] Working principle of the present invention: when in use, the moving motor 15 controls the rotating screw 16 to rotate, so that the moving mold 3 moves along the guide frame 14 and fits against the side of the fixed mold 4, and the heating plate 32 works to preheat the inner wall of the second mold 31, so as to prevent the aluminum alloy solution from contacting the cooled moving mold 3 and the fixed mold 4 when entering the moving mold 3 and the fixed mold 4, and solidifying in advance, resulting in insufficient fluidity of the aluminum alloy solution and being unable to fill the edges of the moving mold 3 and the fixed mold 4;

[0054] Under the action of the lifting cylinder 214, the heat preservation crucible 22 descends, and the fixed cover 25 is sleeved on the outer surface of the feed port 42, and the solenoid valve 28 is opened, so that the aluminum alloy solution passes through the heat preservation crucible 22, and is discharged from the feeding channel 29 through the discharge pipe 212 and the discharge trough 211. The arc surface of the discharge trough 211 slows down the splashing of the aluminum alloy solution, thereby reducing the absorption of gas in the air. With the injection of the aluminum alloy solution, the gas inside the movable mold 3 and the fixed mold 4 passes through the exhaust channel 210 and is discharged from the exhaust hole 27. At this time, the heating plate 32 stops working;

[0055] When the aluminum alloy solution enters between the movable mold 3 and the fixed mold 4 through the feed port 42, the rotating motor 18 controls the rotating disk 13 to rotate inside the support frame 12, thereby rotating the movable mold 3 and the fixed mold 4. Under the action of centrifugal force, the aluminum alloy solution will quickly fill the edges of the movable mold 3 and the fixed mold 4, and the pad 110 at the bottom of the rotating disk 13 will rotate in a circle with the rotation of the rotating disk 13. Since one end of the pad 110 is higher than the other end, the ball 114 first passes through the lower end of the pad 110, and as the pad 110 rotates, the ball 114 and the movable block 113 are gradually squeezed to compress the return spring 112. After passing through the pad 110, the reaction force of the return spring 112 is used to make the ball 114 knock on the bottom of the rotating disk 13, so that the movable mold 3 and the fixed mold 4 vibrate, thereby breaking the aluminum alloy solution and discharging it.

[0056] After the casting is completed, the rotation of the rotating disk 13 is stopped, and the semiconductor refrigeration plate 45 starts to work, so that the inner wall of the first mold 41 is cooled quickly, and the heat exchanged by the semiconductor refrigeration plate 45 is accumulated inside the inner cavity 43. Through the operation of the fan assembly 47, the air quickly passes through the interior of the inner cavity 43 and is discharged from the exhaust port 44, thereby achieving rapid cooling of the fixed mold 4.

In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other;
