Description

Technical Field

[0001] This invention relates to the field of industrial manufacturing technology, specifically to a die for manufacturing a lithium battery pack bracket. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They achieve charging and discharging through the migration of lithium ions between the positive and negative electrodes. They have the characteristics of high energy density, long cycle life, low self-discharge rate, and light weight, and are widely used in mobile phones, laptops, electric vehicles, energy storage devices and other fields. They are one of the mainstream rechargeable batteries at present.

[0003] The lithium battery pack bracket is a key load-bearing and fixing structure for lithium battery packs. Its core function is to integrate and securely limit the multiple individual lithium batteries in an orderly manner, preventing the batteries from shifting or colliding and being damaged under conditions such as vehicle driving, vibration, or impact. At the same time, the bracket can provide structural support for the battery pack, protect the internal cells from external mechanical damage, and also help plan heat dissipation channels and optimize the battery pack layout, ensuring the overall safety, stability, and service life of the lithium battery pack. It is an important component to ensure the reliable operation of lithium batteries in scenarios such as new energy vehicles.

[0004] However, the existing lithium battery pack bracket manufacturing mold has the following shortcomings:

[0005] Currently, lithium battery pack brackets on the market have achieved high-speed mass production and high output. However, in order to achieve lightweight and high rigidity, some lithium battery pack brackets often adopt deep cavity structures, dense reinforcing ribs, and integrated mounting interface slots. This results in greater friction due to the large number of contact surfaces during demolding. In addition, since lithium battery pack brackets are mostly made of aluminum alloy, they are prone to react with iron elements on the mold surface at high temperatures to form iron-aluminum intermetallic compounds, leading to sticking to the mold and further increasing the difficulty of demolding. Furthermore, the high cooling shrinkage rate of aluminum alloy leads to uneven stress distribution during demolding. When there is greater friction in some areas, it causes jamming, resulting in deformation and micro-cracks, thereby increasing production costs.

[0006] Therefore, we propose a lithium battery pack bracket manufacturing mold to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a manufacturing mold for a lithium battery pack bracket. After the mold is formed, it enters the demolding stage. A first electric telescopic rod drives the mold base plate to move down, and an adjusting plate drives the limiting mold stop plate to slide down, exposing the air nozzle assembly, the first pressure sensor, and the friction sensor. The air pressure space is divided into multiple parts. A pressurized air pump supplies air through a first throttle valve, and the air nozzle sprays high-pressure airflow. The first pressure sensor provides feedback data, and the airflow is adjusted to achieve balanced thrust. Combined with the friction sensor, the thrust is segmented to ensure uniform force on the model. At the same time, the circulating air pump starts, and the air nozzle washes the model to remove debris. A second electric telescopic rod drives the sealing misalignment plate to allow the slag to leak into the waste bin. When the model is halfway removed, the lifting rod drives the sealing module to rise. The second pressure sensor monitors the air pressure to detect defects. After demolding, all components are reset. Multiple mechanisms work together to achieve closed-loop control, reducing the scrap rate and saving costs.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a lithium battery pack bracket manufacturing mold, comprising a mold body, a demolding mechanism, and a cleaning mechanism, wherein the demolding mechanism is disposed at the bottom of the mold body, and the cleaning mechanism is disposed at the bottom of the mold body;

[0009] The demolding mechanism includes an air nozzle, a first pressure sensor, and a limiting mold plate. The air nozzle is located outside the first pressure sensor, and the first pressure sensor is located at the bottom of the limiting mold plate. The limiting mold plate is used to isolate the first pressure sensor from high temperature, and the first pressure sensor is used to provide a pressure signal to the air nozzle.

[0010] Preferably, the demolding mechanism further includes a pressurizing air pump, which is installed on the outside of the mold body. The top of the pressurizing air pump is connected to a plurality of first throttle valves, and the top of the first throttle valves is connected to an explosion-proof air pipe. The air nozzle is installed at the other end of the explosion-proof air pipe. The first pressure sensor is installed on the outside of the explosion-proof air pipe, and a friction sensor is installed on the outside of the first pressure sensor. The limiting mold baffle is slidably connected to the inside of the mold body, and an adjusting plate is provided on the top of the limiting mold baffle. A pressure feeding device is provided on the top of the mold body, and a molten material cylinder is provided on the top of the pressure feeding device.

[0011] Preferably, the cleaning mechanism includes a sealing plate, which is installed on the top of the mold body, and a device groove is provided on the inner side of the top of the mold body.

[0012] Preferably, a lifting rod is installed inside the device groove, a sealing module is installed at the bottom of the lifting rod, and a second pressure sensor is installed inside the mold body.

[0013] Preferably, the second pressure sensor is located on the outside of the sealing module, and a device chassis is installed at the bottom of the mold body, with a circulating air pump installed on the outside of the device chassis.

[0014] Preferably, the input end of the circulating air pump is connected to an air intake pipe, the other end of the air intake pipe is connected to the device chassis, and the output end of the circulating air pump is connected to an air jet pipe.

[0015] Preferably, the jet pipe is multi-segmented, with a second throttle valve installed on the inner side of two adjacent jet pipe segments, and a jet head connected to the outer side of the jet pipe.

[0016] Preferably, the jet head is located inside the device chassis, and a plurality of first electric telescopic rods are installed at the bottom of the device chassis. A mold base plate is installed at the top of the plurality of first electric telescopic rods, and a sealing plate is slidably connected to the inner side of the mold base plate.

[0017] Preferably, the sealing misalignment plate is tightly fitted with the mold base plate, and a plurality of second electric telescopic rods are installed at the bottom of the sealing misalignment plate, the second electric telescopic rods being located on the inner side of the bottom of the device chassis.

[0018] Preferably, a support is provided on the inner side of the mold body, a cylinder is installed on the bottom inner side of the mold body, the other end of the cylinder is fixedly connected to the device chassis, multiple mold structures are provided on the inner side of the mold body, and a mold groove is opened inside the mold body.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, after the mold forming is completed and the demolding stage begins, the first electric telescopic rod moves the mold base plate downwards, and the adjusting plate moves the limiting mold stop plate upwards, exposing the air nozzle assembly, the first pressure sensor, and the friction sensor. To ensure that the internal air pressure of each model meets the standard and to facilitate targeted pressure adjustment of irregular parts of the model, the air pressure space between the mold groove and the top of the model is divided into multiple parts. The pressurized air pump is turned on, and air is supplied to each explosion-proof air pipe through the first throttle valve. Each air nozzle sprays high-pressure airflow into each area of ​​the top of the model. The first pressure sensor in each area provides real-time feedback of air pressure data, which is then referenced. By adjusting the airflow through the first throttle valve, the air pressure in different areas is controlled to achieve balanced thrust for the overall model. Combined with the friction resistance detected by the friction sensor, the air pressure in the corresponding areas is further adjusted to complete the segmented thrust control. This allows the air pressure in the deep cavity area to be automatically increased, while the air pressure in the thin-walled area remains within a safe range. This solves the problem that when the lithium battery pack bracket is made of special material, oxidation and sticking to the mold can occur. Furthermore, due to the special structure of the lithium battery pack bracket, the high friction in the model during demolding can cause jamming, deformation, and micro-cracks. This avoids the production of such defective products and reduces production costs.

[0021] 2. Simultaneously with the demolding mechanism in operation, the circulating air pump starts, connecting the air inside the device chassis via the suction pipe. After pressurization, the airflow circulates through the jet pipe and is ejected through the jet nozzle. During the demolding process, the jet nozzle works from the initial stage until the model is completely detached, flushing complex parts of the model and removing residual debris and demolding agent. The second electric telescopic rod drives the sealing plate to slide downwards, exposing holes in the mold bottom plate. Cleaning debris falls through the holes and is collected in the waste bin at the bottom. When the model is halfway detached, the lifting rod drives the sealing module to rise, exposing the second pressure sensor and placing it in contact with the support. Within the sealed space of the frame, the air pressure inside the frame is monitored in real time. If there are air holes or fine cracks in the frame model, local air pressure fluctuations will occur, enabling online defect detection. Once demolding is complete, the second electric telescopic rod drives the sealing misalignment plate to slide downwards and re-close with the mold base plate, restoring the sealing performance of the device chassis. The cylinder drives the mold body to rise and reset, and the limiting mold stop plate falls back, preparing for the next cycle. The entire process is coordinated by multiple mechanisms to achieve closed-loop control of pressure and friction, defect prediction, and pre-cleaning. By integrating air pressure demolding with airflow cleaning, production efficiency is improved and the scrap rate is reduced. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: According to Figure 1 - Figure 5As shown, a lithium battery pack bracket manufacturing mold includes a mold body 1, a demolding mechanism 2, and a cleaning mechanism 3. The demolding mechanism 2 is located at the bottom of the mold body 1, and the cleaning mechanism 3 is also located at the bottom of the mold body 1. The demolding mechanism 2 includes an air nozzle 204, a first pressure sensor 205, and a limiting mold baffle 208. The air nozzle 204 is located outside the first pressure sensor 205, and the first pressure sensor 205 is located at the bottom of the limiting mold baffle 208. The limiting mold baffle 208 is used to isolate the first pressure sensor 205 from high temperature. The first pressure sensor 205 is used to provide a pressure signal to the air nozzle 204. The demolding mechanism 2 also includes a pressurizing air pump 201. A pressure pump 201 is installed on the outside of the mold body 1. The top of the pressure pump 201 is connected to multiple first throttle valves 202. The top of the first throttle valves 202 is connected to an explosion-proof air pipe 203. An air nozzle 204 is installed at the other end of the explosion-proof air pipe 203. A first pressure sensor 205 is installed on the outside of the explosion-proof air pipe 203. A friction sensor 206 is installed on the outside of the first pressure sensor 205. A limiting mold stop plate 208 is slidably connected to the inside of the mold body 1.

[0034] The overall effect of Embodiment 1 is as follows: After the mold is formed, it enters the demolding stage. The first electric telescopic rod 313 drives the mold base plate 314 to move downward, and the adjusting plate 207 simultaneously drives the limiting mold stop plate 208 to slide upward, exposing the air nozzle 204 assembly, the first pressure sensor 205 and the friction sensor 206. In order to ensure that the internal air pressure of each model meets the standard and to facilitate targeted adjustment of the pressure in irregular parts of the model, the air pressure space between the mold groove and the top of the model is divided into multiple parts. At this time, the pressurizing air pump 201 is turned on, and the air is supplied to each explosion-proof air pipe 2 through the first throttle valve 202. 03. Air supply: Each air nozzle 204 sprays high-pressure airflow into each area of ​​the top of the model. The first pressure sensor 205 of each area provides real-time feedback on the air pressure data of its area. Based on this data, the airflow is adjusted through the first throttle valve 202 to achieve separate control of the air pressure in different areas, so that the overall model obtains balanced thrust. At the same time, combined with the friction resistance detected by the friction force sensor 206, the air pressure in the corresponding area is further adjusted to complete the segmented thrust control. Finally, the air pressure in the deep cavity area is automatically increased, while the air pressure in the thin-walled area is kept within a safe range, ensuring that the model is subjected to uniform force and preventing stress deformation.

[0035] Example 2: According to Figure 2 - Figure 8As shown, the cleaning mechanism 3 includes a sealing plate 301, which is installed on the top of the mold body 1. A device groove 302 is provided on the inner side of the top of the mold body 1. A lifting rod 303 is installed on the inner side of the device groove 302. A sealing module 304 is installed at the bottom of the lifting rod 303. A second pressure sensor 306 is provided on the inner side of the mold body 1, located outside the sealing module 304. A device chassis 307 is installed at the bottom of the mold body 1. A circulating air pump 308 is installed on the outer side of the device chassis 307. The input end of the circulating air pump 308 is connected to a suction pipe 309, and the other end of the suction pipe 309 is connected to the device chassis 307. The output end of the circulating air pump 308 is connected to a jet pipe 310, which is multi-segmented. A second throttle valve 311 is installed on the inner side of adjacent jet pipe segments 310. The outer side of the jet pipe 310 is connected to the jet head 312, which is located inside the device chassis 307. Multiple first electric telescopic rods 313 are installed at the bottom of the device chassis 307. A mold base plate 314 is installed on the top of the multiple first electric telescopic rods 313. A sealing misalignment plate 315 is slidably connected to the inner side of the mold base plate 314. The sealing misalignment plate 315 is in tight fit with the mold base plate 314. Multiple second electric telescopic rods 316 are installed at the bottom of the sealing misalignment plate 315. The second electric telescopic rods 316 are located inside the bottom of the device chassis 307. A bracket 305 is provided inside the mold body 1. A cylinder 317 is installed inside the bottom of the mold body 1. The other end of the cylinder 317 is fixedly connected to the device chassis 307. Multiple mold structures 4 are provided inside the mold body 1. A mold groove 5 is opened inside the mold body 1.

[0036] The overall effect of Embodiment 2 is as follows: the circulating air pump 308 starts and operates in coordination with the demolding mechanism 2. The input end of the circulating air pump 308 is connected to the inside of the device chassis 307 through the suction pipe 309. After starting, it quickly draws air from the device chassis 307. After the air is pressurized inside the air pump, the pressure increases, and then it is delivered to each jet head 312 through the jet pipe 310. The jet pipe 310 adopts a multi-segment design. The second throttle valve 311 installed between two adjacent segments can adjust the airflow pressure and flow rate in each segment of the jet pipe 310 according to the cleaning needs of different parts of the model, thereby forming a targeted high-speed airflow circulation. When the high-speed airflow is finally ejected through the jet head 312, the model is in the demolding process. The air jet head 312 starts cleaning when the model begins to separate from the mold cavity during the initial demolding process and continues until the model is completely detached from the mold cavity. This continuous airflow pre-cleans complex areas such as deep cavities, grooves between dense ribs, and the inner walls of various holes on the model, reducing the difficulty of subsequent cleaning. Simultaneously with the cleaning operation of the air jet head 312, the second electric telescopic rod 316 is activated. Its output end drives the sealing misalignment plate 315 to slide downwards along the inner track of the mold base plate 314. As the sealing misalignment plate 315 moves, the holes on the mold base plate 314 that were previously covered are exposed. The debris that falls off during cleaning, under the influence of gravity, smoothly leaks through these holes into the waste bin located at the bottom of the device chassis 307 for centralized collection. When the model has traveled halfway out of the mold cavity, the lifting rod 303 begins to operate. The drive device of the lifting rod 303 provides stable power, driving the sealing module 304 connected to its bottom to move upward. As the sealing module 304 rises, the second pressure sensor 306, which was originally covered by it, gradually becomes exposed and enters the relatively sealed space formed with the support model 305. The second pressure sensor 306 immediately starts working, monitoring the air pressure changes in the sealed space in real time. Because the support model 305 may have hidden pores, minor cracks, or leaks during the production process, such defects can cause gas leakage in the sealed space, leading to abnormal fluctuations in local air pressure. The second pressure sensor 306 can detect these leaks. Pressure fluctuations are used to identify whether there are defects in the support 305 model and the approximate location of the defects, thereby realizing online defect detection of the model. After the demolding operation is completely completed, the second electric telescopic rod 316 is activated again, driving the sealing misalignment plate 315 to slide down along the track until it is tightly fitted with the mold base plate 314 again, restoring the sealing performance of the device chassis 307, providing a good foundation for air pressure control and cleaning operations in the next production process. Immediately afterwards, the cylinder 317 starts to work, its piston rod extends, driving the mold body 1 to move upward until it returns to the initial closed position. At the same time, the limiting mold stop plate 208 falls back to the initial position under the action of the corresponding driving mechanism. In the initial state, the limiting mold stop plate 208...This system effectively isolates the air nozzle 204, the first pressure sensor 205, and the friction sensor 206 from the still-warm high-temperature model at the bottom. This ensures the mold can effectively limit and shape the model at high temperatures while preventing direct contact between the high-temperature model and the air nozzle 204, pressure sensor 205, and friction sensor 206. This provides excellent protection for these precision components, extends their service life, and ensures the stability of their detection accuracy. Throughout the process, all mechanisms of the mold operate collaboratively under the unified scheduling of the control system. This multi-mechanism collaborative operation achieves closed-loop control of the model's pressure and friction, allowing for early prediction and detection of potential defects in the model, and simultaneously completing the model's pre-cleaning process.

[0037] The working principle of the entire device is as follows: When the mold is formed and enters the demolding stage, the first electric telescopic rod 313 first drives the mold base plate 314 to move downward, while the adjusting plate 207 drives the limiting mold stop plate 208 to slide upward, exposing the air nozzle 204 assembly, the first pressure sensor 205 and the friction sensor 206. In order to ensure that the air pressure value inside each model meets the standard and to facilitate targeted adjustment of the pressure in irregular parts of the model, the air pressure space between the mold groove and the top of the model is divided into multiple parts. At this time, the pressurizing air pump 201 is turned on to supply air to each explosion-proof air pipe 203 through the first throttle valve 202. Each air nozzle 204 sprays high-pressure airflow into each area of ​​the top of the model. The first pressure sensor 205 of each area provides real-time feedback on the air pressure data of its area. At this time, referring to the real-time air pressure data, the airflow is adjusted through the first throttle valve 202 to control the internal air pressure of different areas separately, so as to achieve balanced thrust on the overall model. At the same time, combined with the friction resistance detected by the friction force sensor 206, the air pressure of the corresponding area is further adjusted, thereby completing the segmented thrust control. Finally, the air pressure in the deep cavity area is automatically increased, and the air pressure in the thin-walled area is within a safe range, ensuring that the model is subjected to uniform force to prevent stress deformation.

[0038] Simultaneously, the circulating air pump 308 starts, connecting the air in the device chassis 307 via the suction pipe 309. After pressurization by the circulating air pump 308, a high-speed airflow is formed through the jet pipe 310, and finally ejected through the jet nozzle 312. At this time, the model is in the demolding process. The jet nozzle 312 starts at the initial stage of the demolding process until the model is completely detached, thereby flushing the complex parts of the model, removing residual debris and mold release agent. The second electric telescopic rod 316 drives the sealing plate 315 to slide downwards, causing the mold base plate 314 to expose holes. The cleaned debris leaks through the holes and is collected in the bottom waste bin. As the model is halfway detached, the lifting rod 303 drives the sealing module 304 to rise. At this time, the second pressure sensor... The device 306 is exposed and located in the sealed space with the support 305. The second pressure sensor 306 monitors the air pressure inside the support 305 in real time. If there are air holes or fine cracks in the support 305 model, the local air pressure will fluctuate, realizing online defect detection. After demolding, the second electric telescopic rod 316 drives the sealing misalignment plate 315 to slide downward and re-close with the mold base plate 314 to restore the sealing of the device chassis 307. The cylinder 317 drives the mold body 1 to rise and reset, and the limiting mold stop plate 208 falls back to prepare for the next cycle. The whole process realizes closed-loop control of pressure and friction, defect prediction and pre-cleaning through multi-mechanism scheduling. By integrating air pressure demolding and airflow cleaning, production efficiency is improved and scrap rate is reduced.
