Description

Technical Field

[0001] The invention belongs to the field of lithium battery manufacturing, in particular to an outer frame forming mold for a lithium battery tray. Background Art

[0002] Lithium batteries are widely used in pure electric vehicles due to their high energy content, long service life, environmental protection, and high power tolerance. During the production process of lithium batteries, in order to ensure the safe transportation and storage of lithium batteries, factories will use lithium battery pallets to store and transport lithium batteries. The outer frame of the lithium battery pallet is an important part of the pallet structure. It is mainly responsible for protecting lithium batteries and providing structural support. Usually, during the production of the outer frame of the lithium battery pallet, a molding mold is needed to process the raw materials into the required outer frame shape.

[0003] The patent with announcement number CN206306327U discloses a mold for forming the outer frame of a lithium battery tray, including an upper mold frame and a lower mold frame. The lower mold frame is provided with a mold core for forming the inner surface of the product. The mold core is a rectangular parallelepiped structure. The upper surface of the mold core is provided with crisscross grooves and a number of depressions of different shapes. The mold core is provided with an ejector hole. The upper mold frame is provided with a molding bottom plate adapted to the mold core. A gap is reserved between the molding bottom plate and the mold core. The molding bottom plate is provided with a protruding structure adapted to the depression. The patent has a simple structure, reasonable design, and low development cost. Through this patent, an outer frame for batch management of lithium battery trays can be manufactured. The upper surface of the mold core forms the bottom surface of the outer frame. The grooves and depressions on the upper surface of the mold core enhance the structural strength of the outer frame after molding.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although the molded outer frame can be demolded, usually, in order to improve production efficiency, multiple outer frames are molded continuously, and in order to ensure the subsequent processing and use of the outer frames, the staff is required to check the appearance quality of the molded outer frames, remove unqualified outer frames, and avoid unqualified outer frames from being put into subsequent processing and use. In the above technical scheme, if the outer frames after demolding are concentrated in the same place, then the multiple outer frames may be messy and cover each other, which is not conducive to the workers to check their appearance quality. It is also time-consuming and labor-intensive for the workers to manually organize the outer frames for inspection. When the method of inspecting each outer frame after molding is adopted, it is not conducive to the workers to compare multiple molded outer frames, affecting the accuracy of the inspection results.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. According to the outer frame forming mold of a lithium battery tray described in the present invention, after the two lower molds are separated, the positioning block can be driven close to the edge of the forming outer frame, and the bottom of the positioning block extends into the rectangular through hole of the forming outer frame. At the same time, the pressing block is driven to descend, and the forming outer frame can be clamped with the cooperation of the pressing block and the positioning block. At this time, the upper mold is driven to rise again. Since the forming outer frame is fixed, the forming outer frame can be smoothly detached from the upper mold, thereby avoiding the situation that the forming outer frame cannot fall off due to the action of gravity because it is mounted on the upper mold, and the forming outer frame needs to be manually removed, which is more convenient.

[0023] 2. The outer frame forming mold of a lithium battery tray described in the present invention can be used in the molded outer frame to separate from the mold cavity, and the clamping and transporting mechanism and the elastic positioning mechanism can be used to move the molded outer frame to the inspection table and place it on the positioning frame. The two positioning plates clamp the molded outer frame. The staff only needs to stand on one side of the inspection table and drive the turntable to rotate to check the appearance quality of multiple molded outer frames in turn. Since each molded outer frame is placed independently, when the staff inspects the molded outer frame, the inspection effect will not be affected by the multiple molded outer frames being messy and covering each other. At the same time, the process of manually arranging the molded outer frames is omitted, which is more convenient and labor-saving. Moreover, since the multiple molded outer frames are placed more regularly, it is also convenient for the staff to compare the appearance qualities of the multiple molded outer frames, further improving the accuracy of the inspection results. Moreover, the staff can drive the positioning frame to rotate to rotate the molded outer frame. At this time, the staff can observe the various positions of the molded outer frame through a fixed viewing angle, eliminating the process of the staff frequently moving their sight to inspect, which is more convenient and When all the forming outer frames are inspected, multiple unqualified forming outer frames can be pushed to the same place by driving the rack to move for subsequent processing, and qualified forming outer frames can be neatly stacked in the inner cavity of the placement frame. Then, the position of the placement frame can be adjusted so that its bottom is aligned with the conveyor belt or the transport trolley, so that the stacked forming outer frames fall onto the conveyor belt or the transport trolley, and the conveyor belt or the transport trolley can drive multiple forming outer frames to the next processing step, thereby facilitating the conveyance of the forming outer frames to the next processing step. , which is beneficial to improving processing efficiency. In addition, when the formed outer frame slides onto the conveyor belt or the transport trolley through the placement frame, the baffle plate can be driven down to cover the opening of the placement frame. When the lowermost formed outer frame is placed on the conveyor belt or the transport trolley, all four sides will be limited. When the lowermost formed outer frame is stable, the placement frame can be driven to move up as a whole, thereby avoiding the situation where the lowermost formed outer frame is moved out of the opening of the placement frame due to the impact force when the formed outer frame falls, resulting in multiple formed outer frames being unable to be neatly stacked, affecting normal transportation.

[0038] Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a lithium battery tray outer frame molding mold, comprising a base 1, a molding table 2 is fixedly connected to one side of the upper end surface of the base 1, and lower molds 30 are slidably connected to both sides of the upper end of the molding table 2, a support frame 26 is fixedly connected to one side of the upper end surface of the molding table 2, two sliding rods 28 are slidably connected to the upper side of the support frame 26, and an upper mold 29 is fixedly connected to the lower end of the sliding rod 28, and an injection port 31 is arranged on one side of the upper mold 29. When the two lower molds 30 are fitted to each other, and the upper mold 29 is fitted to the upper ends of the two lower molds 30, a complete molding cavity can be formed, an inspection table 12 is fixedly connected to one side of the upper end surface of the base 1, and a turntable 13 is rotatably arranged on the upper end surface of the inspection table 12, and a plurality of elastic positioning mechanisms for fixing the molding outer frame are also arranged on the turntable 13;

[0039] The elastic positioning mechanism includes a placement seat 35 fixedly connected to the upper end surface of the rotating disk 13, and positioning frames 37 are rotatably arranged on both sides of the placement seat 35, and positioning plates 38 are slidably connected to both sides of the positioning frame 37;

[0040] The base 1 is also provided with a gripping and transporting mechanism for transferring the formed outer frame to the positioning frame 37;

[0041] The clamping and transporting mechanism includes a support 3 51 fixedly connected to the front side of the upper end of the base 1, the upper end of the support 3 51 is slidably connected to a rack 3 24, the rear end of the rack 3 24 is fixedly connected to a positioning block 47, and one side of the positioning block 47 is slidably connected to a pressure block 48.

[0042] In this embodiment, Figure 4 and Fig.11 As shown, one side of the upper end surface of the support frame 26 is fixedly connected with an electric push rod 3 27, and the piston end of the electric push rod 3 27 is fixedly connected to one side of the upper end surface of the upper mold 29. Both sides of the upper end surface of the forming table 2 are fixedly connected with electric push rods 25, and the piston end of the electric push rod 25 is fixedly connected to one side of the lower mold 30.

[0043] A gear 2 46 is rotatably provided on the upper end of the pillar 3 51, and the gear 2 46 meshes with the tooth block on the surface of the rack 3 24, a motor 8 45 is fixedly connected to one side of the upper end of the pillar 3 51, and the output end of the motor 8 45 is fixedly connected to the gear 2 46, and an electric push rod 5 49 is fixedly connected to one side of the positioning block 47, and the piston end of the electric push rod 5 49 is fixedly connected to the upper end of the pressure block 48.

[0044] Specifically, the electric push rods 25 on both sides are used to drive the lower molds 30 on both sides to move simultaneously until they are in contact, and then the electric push rods 37 are used to drive the upper mold 29 to descend until the upper mold 29 is in contact with the upper ends of the two lower molds 30. At this time, the upper mold 29 and the lower molds 30 form a complete molding cavity, and then the injection molding material is injected into the molding cavity through the injection port 31. After the injection molding material is cooled and formed in the molding cavity, the upper mold 29 is driven to rise, and the two lower molds 30 are separated from each other, so that the molding outer frame is moved out of the molding cavity. In addition, when the upper mold 29 rises, the molding outer frame may also be sleeved on the upper mold 29 and rise with the upper mold 29, resulting in the molding outer frame cannot fall off normally, and it is also necessary to manually remove the molding outer frame, which is more laborious. Therefore, in order to avoid this In this case, after the two lower molds 30 are separated, the motor eight 45 can be used to drive the gear two 46 to rotate, so that the rack three 24 is displaced, and the positioning block 47 is close to the edge of the molding outer frame. Since a plurality of rectangular through holes are arranged at the upper edge of the molding outer frame, the bottom of the positioning block 47 can extend into the rectangular through hole. At the same time, the electric push rod five 49 is used to drive the pressing block 48 to descend, and the molding outer frame can be clamped with the cooperation of the pressing block 48 and the positioning block 47. At this time, the upper mold 29 is driven to rise again. Since the molding outer frame is fixed, the molding outer frame can be smoothly detached from the upper mold 29, thereby avoiding the situation that the molding outer frame is sleeved on the upper mold 29 and cannot fall off under the action of gravity, and the molding outer frame needs to be removed manually, which is more convenient.

[0052] Specifically, although the existing outer frame forming mold of the lithium battery tray can realize the demoulding work of the molded outer frame when in use, usually, in order to improve production efficiency, multiple outer frames will be continuously molded, and in order to ensure the subsequent processing and use effect of the outer frame, the staff is required to check the appearance quality of the molded outer frame, remove unqualified outer frames, and avoid unqualified outer frames from being put into subsequent processing and use. In the prior art, if the outer frames after demoulding are concentrated in the same place, then the multiple outer frames may be messy and cover each other, which is not conducive to the workers to check their appearance quality. When the workers manually organize the outer frames for inspection, it is also time-consuming and labor-intensive. When the method of inspecting each outer frame after molding is adopted, it is not conducive to the workers to compare multiple molded outer frames, which affects the accuracy of the inspection results.

[0053] Therefore, in order to solve the above problem, when the present embodiment is in use, when the molding outer frame is clamped by the positioning block 47 and the pressing block 48 and separated from the upper mold 29, the rack three 24 is continuously driven to slide, so that the molding outer frame can be moved, and the molding outer frame can be moved toward the inspection table 12. Since the upper end surface of the molding table 2 is flush with the upper end surface of the positioning frame 37, the bottom of the molding outer frame can be fitted with the upper end surface of the positioning frame 37 as the rack three 24 moves, and the edge of the molding outer frame will contact the positioning plate 38 and squeeze the positioning plate 38. When the positioning plate 38 moves, the connecting rod 41 rotates and the slider 39 slides, so that the spring 40 is deformed, and under the action of the reaction force of the spring 40, the two positioning plates 38 clamp the molding outer frame. When a molding outer frame is placed on a positioning frame 37, the motor five 33 drives the gear four 32 to rotate, so that the turntable 13 can be rotated, so that the next positioning frame 37 is aligned with the molding table 2, and the above work is repeated, so that the molding outer frame can be transferred to the fixed position. On the positioning frame 37, when the multiple positioning frames 37 are all placed with the molded outer frames, at this time, the staff only needs to stand on one side of the inspection table 12, and by driving the turntable 13 to rotate, the appearance quality of the multiple molded outer frames can be inspected in turn. Since each molded outer frame is placed independently, when the staff inspects the molded outer frames, the inspection effect will not be affected by the multiple molded outer frames being messy and covering each other. At the same time, the process of manually arranging the molded outer frames is omitted, which is more convenient and labor-saving. Moreover, since the multiple molded outer frames are placed more regularly, it is also convenient for the staff to compare the appearance quality of the multiple molded outer frames, further improving the accuracy of the inspection results. Moreover, the staff can drive the positioning frame 37 to rotate by starting the motor 7 36 to rotate the molded outer frame. At this time, the staff can observe the various positions of the molded outer frames through a fixed viewing angle, eliminating the process of the staff frequently moving their sight to inspect, which is more convenient.

[0054] Usually, after the quality inspection of the molded outer frame is completed, the molded outer frame needs to be transported to the subsequent processing step via a conveyor belt or a transport trolley, and in order to facilitate transportation and processing, multiple molded outer frames need to be kept in a stacked state. Since multiple molded outer frames are distributed at various positions on the turntable 13, it is not conducive to transporting the molded outer frames. Therefore, in order to avoid this problem, after the inspection of all molded outer frames is completed, the unqualified molded outer frames are driven to move under the rack 2 11, and the end of the rack 2 11 is aligned with the edge of the molded outer frame. At this time, the motor 6 34 can be used to drive the gear 3 50 to rotate, so that the rack 2 11 moves horizontally, and the end of the rack 2 11 is used to align the molded outer frame. The frame is pushed to make the molded outer frame slide off the positioning frame 37, and a collection container can be placed under the rack 2 11 to collect unqualified molded outer frames for subsequent processing. For qualified molded outer frames, the molded outer frame is driven to move to a position aligned with the bottom opening of the placement frame 7. At this time, the electric push rod 6 52 can be used to drive the push plate 54 to move, and the push plate 54 pushes the molded outer frame into the inner cavity of the placement frame 7. The molded outer frame is placed on the bottom plate 15, and the edge of the molded outer frame is in contact with the inner cavity wall of the placement frame 7. When the angle of the molded outer frame is in contact with the inner cavity angle of the placement frame 7, the motor 4 23 can be used to drive the threaded rod 3 21 to rotate, so that the lifting plate 20 drives multiple lifting rods 43 to rise at the same time, and the push rod 43 can be pushed. The molded outer frame rises, and when the bottom of the molded outer frame is higher than the upper end surface of the support plate 14, the motor 2 16 drives the threaded rods 17 on both sides to rotate, so that the two support plates 14 are close to each other until their upper end surfaces fit with the bottom of the molded outer frame. At this time, the molded outer frame can be supported, and then the above operation is repeated, and each time the molded outer frame rises, the upper molded outer frame will fall on the lower molded outer frame, so that multiple molded outer frames can be neatly stacked in the inner cavity of the placement frame 7, and then the placement frame 7 is driven to rise by the electric push rod 8, and the motor 4 drives the gear 5 to rotate, so that the rack 6 slides, so that the placement frame 7 can be moved away from the top of the turntable 13, and the position of the placement frame 7 is adjusted to align its bottom The conveyor belt or the transport trolley is then used to drive the threaded rod 2 19 to rotate by the motor 3 18, so that the bottom plate 15 slides at the bottom of the placement frame 7 until the bottom plate 15 no longer covers the bottom of the placement frame 7, and then the two support plates 14 are driven away from each other and no longer provide support for the bottom of the molded outer frame. At this time, the stacked molded outer frames will fall onto the conveyor belt or the transport trolley, and then the placement frame 7 is driven to rise, so that the conveyor belt or the transport trolley can drive multiple molded outer frames to be transferred to the next processing step, so that the molded outer frames with qualified appearance quality can be transferred to the conveyor belt or the transport trolley in a neatly stacked state, so as to facilitate the transportation of the molded outer frames to the next processing step, which is conducive to improving the processing efficiency;

[0055] Since the molded outer frame needs to enter the placement frame 7 through the opening at the bottom of the placement frame 7, the height of the bottom opening of the placement frame 7 is greater than the height of the molded outer frame. In order to ensure that the molded outer frame will not deviate when it falls onto the conveyor belt or the transport trolley, the upper end surface of the lowest layer of the molded outer frame cannot be lower than the lower end surface of the placement frame 7 when it is placed on the conveyor belt or the transport trolley. In this way, the placement frame 7 can still limit the molded outer frame when it falls. However, since the bottom of the placement frame 7 is provided with an opening, the lowest molded outer frame may be moved out of the opening of the placement frame 7 due to the impact force, thereby causing multiple molded outer frames to fall. The frames cannot be stacked neatly, affecting normal transportation. Therefore, in order to avoid this situation, when the molded outer frame slides onto the conveyor belt or the transport trolley, the electric push rod 44 can be used to drive the baffle 55 to descend, so that the baffle 55 covers the opening of the placement frame 7. When the lowermost molded outer frame is placed on the conveyor belt or the transport trolley, all four sides will be limited. When the lowermost molded outer frame is stable, the placement frame 7 can be driven to move up as a whole, thereby avoiding the situation where the lowermost molded outer frame is moved out of the opening of the placement frame 7 due to the impact force when the molded outer frame falls, resulting in multiple molded outer frames being unable to be stacked neatly, affecting normal transportation.

[0056] Working principle: The electric push rods 25 on both sides are used to drive the lower molds 30 on both sides to move simultaneously until they fit together, and then the electric push rods 37 are used to drive the upper mold 29 to descend until the upper mold 29 fits together with the upper ends of the two lower molds 30. At this time, the upper mold 29 and the lower mold 30 form a complete molding cavity, and then the injection molding material is injected into the molding cavity through the injection port 31. After the injection molding material is cooled and formed in the molding cavity, the upper mold 29 is driven to rise, and the two lower molds 30 are separated from each other, so that the molding outer frame is moved out of the molding cavity. In addition, when the upper mold 29 rises, the molding outer frame may also be sleeved on the upper mold 29 and rise with the upper mold 29, resulting in the molding outer frame cannot fall off normally, and it is also necessary to manually remove the molding outer frame, which is more laborious. Therefore, in order to avoid this situation, the two lower molds 3 0 After separation, the motor eight 45 can be used to drive the gear two 46 to rotate, so that the rack three 24 is displaced, and the positioning block 47 is close to the edge of the molding outer frame. Since a plurality of rectangular through holes are arranged at the upper edge of the molding outer frame, the bottom of the positioning block 47 can extend into the rectangular through hole. At the same time, the electric push rod five 49 is used to drive the pressing block 48 to descend, and the molding outer frame can be clamped under the cooperation of the pressing block 48 and the positioning block 47. At this time, the upper mold 29 is driven to rise. Since the molding outer frame is fixed, the molding outer frame can be smoothly separated from the upper mold 29, thereby avoiding the situation that the molding outer frame is sleeved on the upper mold 29 and cannot fall off under the action of gravity, and the molding outer frame needs to be manually removed. It is more convenient, and the rack three 24 is continued to be driven to slide, so that the molding outer frame can be The outer frame moves, and the molded outer frame moves toward the inspection table 12. Since the upper end surface of the molding table 2 is flush with the upper end surface of the positioning frame 37, the bottom of the molding outer frame can fit with the upper end surface of the positioning frame 37 as the rack three 24 moves, and the edge of the molding outer frame will contact the positioning plate 38 and squeeze the positioning plate 38. When the positioning plate 38 moves, the connecting rod 41 rotates and the slider 39 slides, so that the spring 40 can be deformed, and under the action of the reaction force of the spring 40, the two positioning plates 38 clamp the molding outer frame. When a molding outer frame is placed on a positioning frame 37, the motor five 33 drives the gear four 32 to rotate, so that the turntable 13 can be rotated, so that the next positioning frame 37 is aligned with the molding table 2, and the above work is repeated to transfer the molding outer frame to the positioning frame 37. When the plurality of positioning frames 37 are all placed with molded outer frames, at this time, the staff only needs to stand on one side of the inspection table 12 and drive the turntable 13 to rotate to inspect the appearance quality of the plurality of molded outer frames in turn. Since each molded outer frame is placed independently, when the staff inspects the molded outer frames, the inspection effect will not be affected by the plurality of molded outer frames being messy or covering each other. At the same time, the process of manually arranging the molded outer frames is omitted, which is more convenient and labor-saving. Moreover, since the plurality of molded outer frames are placed more regularly, it is also convenient for the staff to compare the appearance quality of the plurality of molded outer frames, further improving the accuracy of the inspection result. Moreover, the staff can drive the positioning frame 37 to rotate by starting the motor 7 36 to rotate the molded outer frame.At this time, the staff can observe various positions of the molded outer frame through a fixed viewing angle, eliminating the need for the staff to frequently move their sight lines for inspection, which is more convenient; usually, after the quality inspection of the molded outer frame is completed, the molded outer frame needs to be transported to the subsequent processing step via a conveyor belt or a transport trolley, and in order to facilitate transportation and processing, multiple molded outer frames need to be kept in a stacked state, and since multiple molded outer frames are distributed at various positions on the turntable 13, it is not conducive to transporting the molded outer frames. Therefore, in order to avoid this problem, after the inspection of all molded outer frames is completed, the unqualified molded outer frames are driven to move to the bottom of the rack 2 11, and the end of the rack 2 11 is aligned with the edge of the molded outer frame. At this time, the motor 6 34 can be used The gear 3 50 is driven to rotate, so that the rack 2 11 moves horizontally, and the end of the rack 2 11 is used to push the forming outer frame, so that the forming outer frame slides off the positioning frame 37, and a collection container can be placed under the rack 2 11 to collect unqualified forming outer frames for subsequent processing. For qualified forming outer frames, the forming outer frame is driven to move to a position aligned with the bottom opening of the placement frame 7. At this time, the electric push rod 6 52 can be used to drive the push plate 54 to move, and the push plate 54 pushes the forming outer frame into the inner cavity of the placement frame 7. The forming outer frame is placed on the bottom plate 15, and the edge of the forming outer frame is in contact with the inner cavity wall of the placement frame 7. When the angle of the forming outer frame is in contact with the inner cavity angle of the placement frame 7, the motor 4 23 can be used to drive the threaded rod 3 21 to rotate, so that the lifting plate 20 drives multiple tops The lifting rods 43 rise at the same time, which can push the forming outer frame to rise. When the bottom of the forming outer frame is higher than the upper end surface of the support plate 14, the motor 2 16 drives the threaded rods 17 on both sides to rotate, so that the two support plates 14 are close to each other until their upper end surfaces are in contact with the bottom of the forming outer frame. At this time, the forming outer frame can be supported, and then the above operation is repeated. Each time the forming outer frame rises, the upper forming outer frame will fall on the lower forming outer frame, so that multiple forming outer frames can be neatly stacked in the inner cavity of the placement frame 7. Then, the placement frame 7 is driven to rise by the electric push rod 8, and the motor 4 drives the gear 5 to rotate to slide the rack 6, so that the placement frame 7 can be moved away from the top of the turntable 13. By adjusting the position of the placement frame 7, its bottom is aligned with the conveyor belt or the transport trolley, and then Then, the motor 3 18 is used to drive the threaded rod 2 19 to rotate, so that the bottom plate 15 slides at the bottom of the placement frame 7 until the bottom plate 15 no longer covers the bottom of the placement frame 7, and then the two support plates 14 are driven to move away from each other and no longer provide support for the bottom of the molded outer frame. At this time, the stacked molded outer frames will fall onto the conveyor belt or the transport trolley, and then the placement frame 7 is driven to rise, so that the conveyor belt or the transport trolley can drive multiple molded outer frames to be transferred to the next processing step, so that the molded outer frames with qualified appearance quality can be transferred to the conveyor belt or the transport trolley in a neatly stacked state, so as to facilitate the transportation of the molded outer frames to the next processing step, which is beneficial to improving the processing efficiency; because the molded outer frames need to enter the placement frame 7 through the opening at the bottom of the placement frame 7, soThe height of the bottom opening of the placement frame 7 is greater than the height of the formed outer frame. In order to ensure that the formed outer frame will not deviate when it falls onto the conveyor belt or the transport trolley, the upper end surface of the bottommost formed outer frame cannot be lower than the lower end surface of the placement frame 7 when it is placed on the conveyor belt or the transport trolley. In this way, the placement frame 7 can still limit the formed outer frame when it falls. However, since the bottom of the placement frame 7 is provided with an opening, the bottommost formed outer frame may be moved out of the opening of the placement frame 7 due to the impact force, thereby causing multiple formed outer frames to be unable to be neatly stacked, affecting normal transportation. Therefore, in order to avoid this situation, when the molded outer frame slides onto the conveyor belt or the transport trolley, the electric push rod 44 can be used to drive the baffle 55 to descend, so that the baffle 55 covers the opening of the placement frame 7. When the molded outer frame at the bottom is placed on the conveyor belt or the transport trolley, the surroundings will be limited. When the molded outer frame at the bottom is stable, the placement frame 7 can be driven to move up as a whole, thereby avoiding the situation that when the molded outer frame falls, the molded outer frame at the bottom is moved out of the opening of the placement frame 7 due to the impact force, resulting in multiple molded outer frames being unable to be neatly stacked, affecting normal transportation.
