Description

Technical Field

[0001] The present invention relates to the field of industrial manufacturing technology, and in particular to a mold for manufacturing a lithium battery pack bracket. Background Art

[0002] Lithium 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. They are widely used in mobile phones, laptops, electric vehicles, energy storage equipment and other fields, and are one of the current mainstream secondary batteries.

[0003] The lithium battery pack bracket is the key load-bearing and fixing structure of the lithium battery pack. Its core function is to integrate multiple single lithium batteries in an orderly manner and firmly limit their position to prevent the batteries from displacement, collision and damage 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 battery cells from external mechanical damage, and assist in planning heat dissipation channels and optimizing battery pack layout to ensure 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: Currently, lithium battery pack brackets on the market have achieved high-speed mass production during manufacturing, with high output. However, in order to achieve lightweight and high rigidity, some lithium battery pack brackets often adopt deep cavity structures, dense reinforcement ribs and integrated installation interface slots, which result in greater friction due to more contact surfaces during demolding. In addition, since lithium battery pack brackets are mostly made of aluminum alloy, it is easy to react with the iron elements on the mold surface at high temperatures to form iron-aluminum intermetallic compounds, resulting in mold sticking, further increasing the difficulty of demolding. In addition, the aluminum alloy has a high cooling shrinkage rate, and the stress distribution is uneven during demolding. When the friction is large in some places and jamming occurs, deformation and microcracks are caused, thereby increasing production costs.

[0005] Therefore, we proposed a lithium battery pack bracket manufacturing mold to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a lithium battery pack bracket manufacturing mold. After the mold is formed, it enters the demolding stage. The first electric telescopic rod drives the mold bottom plate to move downward, and the adjustment plate drives the limit mold resistance plate to slide up, exposing the air nozzle assembly, the first pressure sensor and the friction sensor. The air pressure space is divided into multiple parts. The pressurized air pump supplies air through the first throttle valve, and the air nozzle sprays high-pressure airflow. The first pressure sensor feeds back data, adjusts the airflow to achieve balanced thrust, and combines with the friction sensor to complete thrust segmentation control to ensure that the model is uniformly stressed. At the same time, the circulating air pump is started, and the jet head flushes the model to remove debris. The second electric telescopic rod drives the sealing offset plate to leak the slag into the waste bucket. When the model is half detached, the lifting rod drives the sealing module to rise, and the second pressure sensor monitors the air pressure to achieve defect detection. After the demolding is completed, the components are reset, and multiple mechanisms work together to achieve closed-loop control, reduce the scrap rate and save costs.

[0009] Preferably, the cleaning mechanism comprises a sealing plate, which is arranged on the top of the mold body, and a device groove is provided on the inner side of the top of the mold body.

[0010] Preferably, a lifting rod is installed on the inner side of the device groove, a sealing module is installed on the bottom of the lifting rod, and a second pressure sensor is provided on the inner side of the mold body.

[0012] 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 injection pipe.

[0013] Preferably, the air jet pipe is multi-sectioned, a second throttle valve is installed on the inner side of two adjacent sections of the air jet pipe, and an air jet head is connected to the outer side of the air jet pipe.

[0015] Preferably, the sealing staggered plate is tightly fitted with the mold bottom plate, and a plurality of second electric telescopic rods are installed at the bottom of the sealing staggered plate, and the second electric telescopic rods are located on the inner side of the bottom of the device chassis.

[0016] Preferably, a bracket is provided on the inner side of the mold body, a cylinder is installed on the inner side of the bottom of the mold body, the other end of the cylinder is fixedly connected to the device chassis, a plurality of mold structures are provided on the inner side of the mold body, and a model groove is opened inside the mold body.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the demoulding stage after the mold forming is completed, the first electric telescopic rod drives the mold bottom plate to move downward, and the adjustment plate drives the limit mold baffle to slide upward, exposing the air nozzle assembly, the first pressure sensor and the friction sensor. In order to ensure that the internal air pressure of each model meets the standard and facilitate targeted pressure adjustment of irregular parts of the model, the mold groove and the air pressure space on the top of the model are 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 air to each area on the top of the model. The first pressure sensor in each area feeds back air pressure data in real time. The first throttle valve regulates the airflow, controlling the air pressure in different areas to achieve balanced thrust for the entire model. Combined with the friction resistance of each part detected by the friction sensor, the air pressure in the corresponding area is further adjusted to achieve segmented thrust control. This automatically increases the air pressure in deep cavity areas and keeps the air pressure in thin-walled areas within a safe range. This solves the problem of oxidation and mold sticking caused by the special material used in the lithium battery pack bracket. Due to the special structure of the lithium battery pack bracket, the model is subjected to high friction during demolding, causing deformation and micro-cracks. This prevents the production of such defective products and reduces production costs. 2. While the demoulding mechanism is running, the circulating air pump is started, and the air in the chassis of the device is connected through the suction pipe. After pressurization, it forms a high-speed airflow circulation through the jet pipe and is ejected through the jet head. During the demoulding process of the model, the jet head works from the initial stage to the complete separation of the model, flushing the complex parts of the model, removing residual debris and release agent. The second electric telescopic rod drives the sealing staggered plate to slide downward, so that the bottom plate of the mold leaks out of the hole, and the cleaned slag leaks into the bottom waste bucket through the hole for collection. When the model is halfway out, the lifting rod drives the sealing module to rise, and the second pressure sensor is exposed and in contact with the support In the sealed space of the bracket, the air pressure in the bracket is monitored in real time. If the bracket model has pores or fine cracks, the local air pressure fluctuates, and the defect is detected online. After demoulding is completed, the second electric telescopic rod drives the sealing staggered plate to slide downward and re-seal with the mold bottom plate to restore the sealing of the device chassis. The cylinder drives the mold body to rise and reset, and the limit mold baffle falls back to prepare for the next cycle. The whole process is dispatched by multiple mechanisms to achieve pressure and friction closed-loop control, defect prediction and pre-cleaning. The integrated cooperation of air pressure demoulding and airflow cleaning can improve production efficiency and reduce scrap rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1: According to Figure 1 - Figure 5As shown, a lithium battery pack bracket manufacturing mold includes a mold body 1, a demoulding mechanism 2 and a cleaning mechanism 3. The demoulding mechanism 2 is arranged at the bottom of the mold body 1, and the cleaning mechanism 3 is arranged at the bottom of the mold body 1. The demoulding mechanism 2 includes an air nozzle 204, a first pressure sensor 205 and a limit mold baffle 208. The air nozzle 204 is arranged on the outside of the first pressure sensor 205, and the first pressure sensor 205 is arranged at the bottom of the limit mold baffle 208. The limit 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 for the air nozzle 204. The demoulding mechanism 2 also includes a pressurized air pump 201. The compressed air pump 201 is installed on the outside of the mold body 1, and the top of the compressed air pump 201 is connected to multiple first throttle valves 202, and the top of the first throttle valve 202 is connected to an explosion-proof air pipe 203. The air nozzle 204 is installed at the other end of the explosion-proof air pipe 203, and the 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.

[0023] The effect achieved by the entire embodiment 1 is as follows: after the mold forming is completed, the demoulding stage begins. The first electric telescopic rod 313 drives the mold bottom plate 314 to move downward, and the adjustment plate 207 simultaneously drives the limit mold blocking plate 208 to slide upward, so that the air nozzle 204 component, the first pressure sensor 205 and the friction sensor 206 are exposed. In order to ensure that the internal air pressure of each model meets the standard and to facilitate targeted adjustment of the pressure of irregular parts of the model, the air pressure space of the mold groove and the top of the model is divided into multiple parts. At this time, the pressurized air pump 201 is turned on, and air is supplied to each explosion-proof air pipe 202 through the first throttle valve 202. 03 Air supply, each air nozzle 204 sprays high-pressure airflow to each area on the top of the model. The first pressure sensor 205 in each area provides real-time feedback of the air pressure data of the area. Referring to this data, the airflow flowing through 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 of each part detected by the friction sensor 206, the air pressure in the corresponding area is further adjusted to complete the thrust segmentation control, and finally the air pressure in the deep cavity area is automatically increased, and the air pressure in the thin-walled part is within a safe range, ensuring that the model is evenly stressed and preventing stress deformation.

[0024] Example 2: According to Figure 2 - Figure 8As shown, the cleaning mechanism 3 includes a sealing plate 301, which is arranged on the top of the mold body 1, and a device groove 302 is opened on the inner side of the top of the mold body 1. A lifting rod 303 is arranged on the inner side of the device groove 302, and a sealing module 304 is arranged on the bottom of the lifting rod 303. A second pressure sensor 306 is provided on the inner side of the mold body 1, and the second pressure sensor 306 is located on the outer side of the sealing module 304. A device chassis 307 is arranged on the bottom of the mold body 1, and a circulating air pump 308 is arranged on the outer side of the device chassis 307. The input end of the circulating air pump 308 is connected to the 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 the injection pipe 310. The injection pipe 310 has multiple sections, and the inner sides of two adjacent sections of the injection pipe 310 are provided with a second throttle valve 311. The outside of the injection pipe 310 is connected to the injection head 312, and the injection head 312 is located on the inner side of the device chassis 307. A plurality of first electric telescopic rods 313 are installed at the bottom of the device chassis 307, and a mold base 314 is installed on the top of the plurality of first electric telescopic rods 313. A sealing staggered plate 315 is slidably connected to the inner side of the mold base 314, and the sealing staggered plate 315 is tightly fitted with the mold base 314. A plurality of second electric telescopic rods 316 are installed at the bottom of the sealing staggered plate 315, and the second electric telescopic rods 316 are located on the inner side of the bottom of the device chassis 307. A bracket 305 is provided on the inner side of the mold main body 1, and a cylinder 317 is installed on the inner side of the bottom of the mold main body 1. The other end of the cylinder 317 is fixedly connected to the device chassis 307. A plurality of mold structures 4 are provided on the inner side of the mold main body 1, and a model groove 5 is opened inside the mold main body 1.

[0025] The effect achieved by the entire embodiment 2 is as follows: the start-up of the circulating air pump 308 is coordinated with the operation process of the demoulding mechanism 2, and 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, the air in the device chassis 307 is quickly extracted. After the air is pressurized inside the air pump, the pressure increases and is then transported to each nozzle 312 through the jet pipe 310. The jet pipe 310 adopts a multi-stage design. The second throttle valve 311 installed between two adjacent sections can adjust the airflow pressure and flow in each section of the jet pipe 310 according to the cleaning requirements 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 process of demoulding and the jet is The nozzle 312 is started when the model and the mold cavity begin to separate at the initial stage of demoulding, and continues until the model is completely separated from the mold cavity, thereby continuously flushing the airflow to pre-clean the deep cavity grooves, gaps between dense ribs, and complex parts of the inner walls of various holes on the model, reducing the difficulty of subsequent cleaning. While the nozzle 312 is cleaning, the second electric telescopic rod 316 is started synchronously, and its output end drives the sealing staggered plate 315 to slide downward along the inner track of the mold bottom plate 314. As the sealing staggered plate 315 moves, the holes on the mold bottom plate 314 that were originally blocked by it are exposed. Under the action of gravity, the cleaning residues smoothly flow through these holes into the waste bucket set at the bottom of the device chassis 307 for centralized collection. When the model has reached half of its travel out of the mold cavity, the lifting rod 303 starts to operate. The driving device of the lifting rod 303 provides stable power to drive the sealing module 304 connected to its bottom to move upward. As the sealing module 304 rises, the second pressure sensor 306 originally covered by it is gradually exposed and enters the relatively sealed space formed with the bracket 305 model. The second pressure sensor 306 immediately starts to work and monitors the air pressure changes in the sealed space in real time. Since the bracket 305 model may have hidden pores or fine cracks, leaks and other defects during the production process, such defects will cause the gas in the sealed space to leak, thereby causing abnormal fluctuations in local air pressure. The second pressure sensor 306 can detect the air pressure in the sealed space. The pressure fluctuation is used to identify whether there are defects in the bracket 305 model and the approximate location of the defects, thereby realizing online defect detection of the model. When the demoulding operation is completely completed, the second electric telescopic rod 316 is started again, driving the sealing staggered plate 315 to slide downward along the track until it is tightly fitted with the mold bottom plate 314 again, restoring the sealing of the device chassis 307, and providing a good foundation for the air pressure control and cleaning operation in the next production process. Immediately afterwards, the cylinder 317 starts working, and 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 blocking plate 208 falls back to the initial position under the action of the corresponding driving mechanism. Among them, when the limiting mold blocking plate 208 is in the initial state,The air nozzle 204, first pressure sensor 205, and friction sensor 206 are isolated from the hot mold at the bottom, which has not yet cooled. This ensures that the mold can effectively limit and shape the mold at high temperature while preventing the hot mold from directly contacting the air nozzle 204, first pressure sensor 205, and friction sensor 206. This effectively protects these precision components, extends their service life, and ensures the stability of their detection accuracy. Throughout the entire process, the various mechanisms of the mold operate in coordination under the unified scheduling of the control system. Through this coordinated operation of multiple mechanisms, closed-loop control of the model's pressure and friction is achieved, allowing for early prediction and detection of potential defects in the model, while also completing the pre-cleaning of the model.

[0026] The working principle of the entire device is as follows: when the mold is formed and enters the demoulding stage, the first electric telescopic rod 313 first drives the mold bottom plate 314 to move downward, and at the same time the adjustment plate 207 drives the limit mold block 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 of irregular parts of the model, the mold groove and the air pressure space on the top of the model are divided into multiple parts. At this time, the pressurized 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 to each area on the top of the model. The first pressure sensor 205 in each area provides real-time feedback of the air pressure data in the area. At this time, the real-time air pressure data is referred to and the air flow is adjusted through the first throttle valve 202 to control the internal air pressure of different areas respectively, so as to achieve balanced thrust for the entire model. At the same time, the friction resistance of each part detected by the friction sensor 206 is combined to further adjust the air pressure of the corresponding area, thereby completing the thrust segmentation control, and finally achieving the automatic increase of the air pressure in the deep cavity area and the air pressure in the thin-walled part within a safe range, ensuring that the model is evenly stressed to prevent stress deformation.

[0027] At the same time, the circulating air pump 308 is started, and the air in the device chassis 307 is connected through the suction pipe 309. After the circulating air pump 308 is pressurized, a high-speed air flow circulation is formed through the jet pipe 310, and finally ejected through the jet head 312. At this time, the model is in the demoulding process. The jet head 312 starts at the early stage of the demoulding process until the model is completely separated, thereby flushing the complex parts of the model and removing residual debris and release agent. The second electric telescopic rod 316 drives the sealing staggered plate 315 to slide downward, so that the mold bottom plate 314 leaks out of the hole, and the cleaned slag leaks into the bottom waste bucket through the hole for collection. When the model is halfway out, the lifting rod 303 drives the sealing module 304 to rise. At this time, the second pressure sensor The device 306 leaks out and is in the sealed space with the bracket 305. The second pressure sensor 306 monitors the air pressure in the bracket 305 in real time. If the bracket 305 model has pores or fine cracks, the local air pressure will fluctuate, realizing online defect detection. After demoulding is completed, the second electric telescopic rod 316 drives the sealing staggered plate 315 to slide downward and re-close with the mold bottom 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 limit mold stop plate 208 falls back to prepare for the next cycle. The whole process is dispatched by multiple mechanisms to realize pressure and friction closed-loop control, defect prediction and pre-cleaning. The integrated cooperation of air pressure demoulding and airflow cleaning can improve production efficiency and reduce scrap rate.
