Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a battery box lower cover mold with auxiliary cooling forming function. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product. Injection molds are classified into two types according to their molding characteristics: thermosetting plastic molds and thermoplastic plastic molds; according to their molding process: transfer molds, blow molds, casting molds, thermoforming molds, hot press molds (compression molds), injection molds, etc. Among them, hot press molds can be further divided into three types based on the overflow method: overflow type, semi-overflow type, and non-overflow type; injection molds can be divided into two types based on the gating system: cold runner molds and hot runner molds; and according to the loading and unloading method: movable type and fixed type.

[0003] However, traditional battery box bottom cover molds often face several problems during the forming process. Firstly, during injection molding, the molten plastic carries a significant amount of heat when injected into the mold cavity. Traditional molds rely on relatively simple and inefficient heat dissipation methods, typically depending solely on the natural heat dissipation of the mold material itself. This results in a slow temperature drop inside the mold cavity, leading to a longer cooling time for the battery box bottom cover within the cavity, thus impacting the entire production cycle and reducing production efficiency. Secondly, untimely and uneven heat dissipation can cause uneven shrinkage of the battery box bottom cover during cooling. This can lead to dimensional deviations, deformation, and other quality issues, failing to meet the high-precision, high-quality assembly requirements of battery boxes. For example, in applications requiring high precision in the fit between the battery box bottom cover and top cover, as well as the internal battery pack, dimensional deviations caused by uneven cooling can reduce the sealing performance of the battery box, affecting battery life and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a battery box lower cover mold with auxiliary cooling forming function, specifically relating to the field of injection mold technology, to solve the problems mentioned in the background art of the traditional battery box lower cover mold in terms of untimely and uneven heat dissipation and poor cooling effect during the forming process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery box lower cover mold with auxiliary cooling forming function, including a processing table and a cooling mechanism. Cooling fans are fixedly installed on the left and right sides of the processing table, an indicator light is fixedly connected to the top of the processing table, a forming mechanism is connected through the top of the processing table, and a cooling mechanism is fixedly installed inside the forming mechanism.

[0006] The cooling mechanism includes a temperature sensor mounted on one side of the forming mechanism. A cooling plate is fixedly installed inside the forming mechanism, and a heat-conducting layer is fixedly installed on top of the cooling plate. A water inlet is fixedly connected to one side of the cooling plate, and a water outlet is fixedly installed on one side of the cooling plate. A first connecting pipe is fixedly connected to one end of the water inlet, and a second connecting pipe is fixedly connected to one end of the water outlet. A solenoid valve is fixedly installed on the outer ring of the first connecting pipe. A first water pump is fixedly connected to one end of the first connecting pipe, and a second water pump is fixedly installed to one end of the second connecting pipe. A cooling tank is fixedly connected to one end of the first water pump, and a water circulation radiator is fixedly installed inside the cooling tank.

[0007] Preferably, there are two sets of cooling fans, which are symmetrically distributed on the processing table, and the heat-conducting layer is tightly attached to the cooling plate.

[0008] Preferably, the second connecting pipe is the same size as the first connecting pipe, and a sealing ring is provided at the connection between the first connecting pipe and the water inlet, and a sealing ring is provided at the connection between the second connecting pipe and the water outlet.

[0009] Preferably, the forming mechanism includes a high-strength corrugated pipe that runs through the top of the processing table. Hydraulic cylinders are fixedly installed on both sides of the upper interior of the processing table. One end of each hydraulic cylinder is fixedly connected to an upper mold base. An upper mold body is fixedly installed below the upper mold base. Guide grooves are formed around the bottom of the upper mold body. Guide columns are slidably connected inside the guide grooves. A lower mold body is fixedly connected to the bottom end of each guide column. A lower mold base is fixedly installed below the lower mold body.

[0010] Preferably, four sets of guide posts are provided, and the outer ring size of the guide posts matches the inner size of the guide groove.

[0011] Preferably, two sets of hydraulic cylinders are provided and symmetrically distributed on the upper mold base, and the upper mold body and the lower mold body are used in conjunction.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This mold, through the inclusion of a temperature sensor, cooling plate, heat-conducting layer, water inlet, water outlet, first connecting pipe, second connecting pipe, solenoid valve, first water pump, second water pump, cooling tank, and water circulation radiator, and by incorporating a high-strength corrugated pipe, allows the feed pipe to extend flexibly with the operation of the hydraulic cylinder, effectively preventing pipe rupture. During the mold closing stage, the hydraulic cylinder begins operation and drives the upper mold base downwards. The upper mold base not only supports the upper mold body but also accurately transmits the power provided by the hydraulic cylinder to the upper mold body. The guide groove and guide post at the bottom of the upper mold body cooperate to achieve precise alignment with the lower mold body, thus forming the upper part of the closed cavity, together constituting a complete cavity. When molten plastic is injected into this cavity, it gradually forms the shape of the battery box lower cover. During the injection molding process, the temperature sensor monitors the temperature inside the molding mechanism in real time and transmits the acquired data to the control system promptly. During injection molding, the molten plastic carries a significant amount of heat, which is conducted to the cooling plate. The heat-conducting layer above the cooling plate optimizes heat transfer, dispersing the absorbed heat more evenly. For coolant circulation, the cooling plate, through an inlet on one side, a connected first pipe, a first water pump, and a cooling tank, forms the coolant input path. Simultaneously, the cooling plate's outlet on the other side, connected to a second pipe and a second water pump, forms the coolant output path, thus completing the coolant circulation process between the cooling plate and the cooling tank. The control system precisely regulates the solenoid valve based on feedback from the temperature sensor, achieving precise control of the coolant flow. A water-circulating radiator inside the cooling tank dissipates heat from the returning coolant, allowing for recycling and ensuring uniform cooling of the battery box cover during the molding process. By utilizing the real-time temperature monitoring function of the temperature sensor within the molding mechanism, and then using the feedback data to precisely control the solenoid valve opening, the coolant flow can be accurately adjusted. This intelligent temperature control method ensures that the temperature inside the mold cavity remains within a suitable range, effectively preventing problems such as insufficient cooling and deformation due to excessively high temperatures, and excessive cooling due to excessively low temperatures, which can affect product quality. It truly achieves refined management of the cooling process, thereby improving the molding quality of the product. Simultaneously, the heat-conducting layer above the cooling plate can more evenly distribute the absorbed heat, allowing the coolant to absorb heat more evenly during circulation. This ensures that the temperature drop of the battery box bottom cover is relatively uniform throughout the cooling and molding process, effectively preventing quality problems such as dimensional deviations and uneven shrinkage caused by uneven cooling.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a battery box lower cover mold with auxiliary cooling forming function, including a processing table 1 and a cooling mechanism 5. Cooling fans 2 are fixedly installed on the left and right sides of the processing table 1, and a signal light 3 is fixedly connected to the top of the processing table 1. A forming mechanism 4 is connected through the top of the processing table 1, and a cooling mechanism 5 is fixedly installed inside the forming mechanism 4.

[0020] The cooling mechanism 5 includes a temperature sensor 501, which is installed on one side of the forming mechanism 4. A cooling plate 502 is fixedly installed inside the forming mechanism 4. A heat-conducting layer 503 is fixedly installed on the top of the cooling plate 502. A water inlet 504 is fixedly connected to one side of the cooling plate 502, and a water outlet 505 is fixedly installed on one side of the cooling plate 502. A first connecting pipe 506 is fixedly connected to one end of the water inlet 504, and a second connecting pipe 507 is fixedly connected to one end of the water outlet 505. A solenoid valve 508 is fixedly installed on the outer ring of the first connecting pipe 506. A first water pump 509 is fixedly connected to one end of the first connecting pipe 506, and a second water pump 510 is fixedly installed to one end of the second connecting pipe 507. A cooling box 511 is fixedly connected to one end of the first water pump 509, and a water circulation radiator 512 is fixedly installed inside the cooling box 511. First, the temperature sensor 501 is installed on one side of the forming mechanism 4 to monitor the temperature inside the forming mechanism 4 in real time throughout the process. The acquired temperature data is transmitted to the corresponding control system in real time. The cooling plate 502, fixedly installed inside the forming mechanism 4, is the core component for heat transfer and absorption. When the mold performs injection molding, a large amount of heat brought in by the molten plastic is conducted to the forming mechanism 4 and then transferred to the cooling plate 502. The heat-conducting layer 503 fixedly installed above the cooling plate 502 optimizes heat conduction, quickly and evenly dispersing the heat absorbed by the cooling plate 502, ensuring a reasonable distribution of heat in and around the cooling plate 502, so that the coolant can absorb this heat more efficiently. Regarding coolant circulation, the inlet 504 fixedly connected to one side of the cooling plate 502, the first connecting pipe 506 connected thereto, the first water pump 509 installed at one end of the first connecting pipe 506, and the cooling tank 511 connected to the other end of the first water pump 509 together constitute the coolant input path. During operation, the first water pump 509 starts, drawing coolant from the cooling tank 511 and steadily delivering it to the inlet 504 of the cooling plate 502 via the first connecting pipe 506, allowing the coolant to smoothly enter the flow channels inside the cooling plate 502. Simultaneously, the outlet 505 fixedly located on the other side of the cooling plate 502, the second connecting pipe 507 connecting the outlet 505, and the second water pump 510 installed at one end of the second connecting pipe 507 establish the coolant output path. After the coolant absorbs heat inside the cooling plate 502, the heat-carrying coolant flows out from the outlet 505, is drawn by the second water pump 510 via the second connecting pipe 507, and is then returned to the cooling tank 511, thus completing the complete circulation path of the coolant between the cooling plate 502 and the cooling tank 511. The control system precisely regulates the solenoid valve 508 based on the internal temperature of the forming mechanism 4 fed back by the temperature sensor 501.When the temperature sensor 501 detects that the internal temperature of the forming mechanism 4 is too high, the control system adjusts the solenoid valve 508 to increase its opening, thereby increasing the flow rate of the coolant and allowing it to flow more quickly through the cooling plate 502, thus accelerating the cooling speed. Conversely, when the temperature sensor 501 detects that the internal temperature of the forming mechanism 4 is too low, the control system adjusts the solenoid valve 508 accordingly to decrease its opening, appropriately reducing the flow rate of the coolant to maintain a suitable cooling speed and avoid over-cooling that could affect product quality. Finally, the water circulation radiator 512, which is fixedly installed inside the cooling tank 511, is a key component for ensuring continuous and effective cooling of the coolant. When the coolant carrying heat is returned to the cooling tank 511, the water circulation radiator 512 uses its own heat dissipation mechanism to dissipate the heat in the coolant into the surrounding environment, restoring the coolant to a suitable temperature so that it can be drawn back by the first water pump 509 and recycled, continuously providing effective cooling capacity to the cooling plate 502 and ensuring that the forming mechanism 4 and the battery box cover being formed are uniformly cooled and formed under suitable temperature conditions.

[0021] Furthermore, two sets of cooling fans 2 are symmetrically distributed on the processing table 1. The heat-conducting layer 503 and the cooling plate 502 are tightly bonded together. Through the arrangement of the cooling fans 2, the cooling fans 2 provide auxiliary heat dissipation for the entire processing table 1 and its surrounding environment. During the mold operation, the injection molding operation will cause the temperature of the forming mechanism 4 and other related components to rise. Although the cooling mechanism 5 cools the inside of the forming mechanism 4, the surrounding areas such as the processing table 1 may also experience temperature increases due to heat conduction and other factors. By continuously rotating, the cooling fans 2 promote rapid airflow in the surrounding area, which can promptly remove the heat accumulated in and around the processing table 1, reduce the temperature of the area, and prevent local overheating from adversely affecting the mold and processing process, such as avoiding mold deformation or affecting processing accuracy due to overheating.

[0022] Furthermore, the second connecting pipe 507 is the same size as the first connecting pipe 506. A sealing ring is provided at the connection between the first connecting pipe 506 and the inlet 504, and a sealing ring is provided at the connection between the second connecting pipe 507 and the outlet 505. Through the design of the first connecting pipe 506, the sealing ring at the connection between the first connecting pipe 506 and the inlet 504 plays a crucial sealing role. Driven by the first water pump 509, the coolant flows at high speed through the first connecting pipe 506 and enters the inlet 504 of the cooling plate 502. If there is no good seal here, the coolant may leak from the connection, which will not only waste the coolant, but may also contaminate the mold and the surrounding environment, and may even affect the normal cooling function of the mold, resulting in insufficient cooling during the molding of the battery box bottom cover and product quality problems. The sealing ring can fit tightly at the connection, effectively filling any tiny gaps that may exist at the connection, ensuring that the coolant can only flow smoothly into the inlet 504 along the predetermined path, i.e. from the first connecting pipe 506, without any leakage.

[0023] Furthermore, the forming mechanism 4 includes a high-strength corrugated pipe 401, which is connected through the top of the processing table 1. Hydraulic cylinders 402 are fixedly installed on both sides of the upper part of the processing table 1. One end of the hydraulic cylinder 402 is fixedly connected to an upper mold base 403. An upper mold body 404 is fixedly installed below the upper mold base 403. Guide grooves 405 are opened around the bottom of the upper mold body 404. Guide columns 406 are slidably connected inside the guide grooves 405. A lower mold body 407 is fixedly connected to the bottom end of the guide column 406. A lower mold base 408 is fixedly installed below the lower mold body 407. By setting the high-strength corrugated pipe 401, the feed pipe can be extended when the hydraulic cylinder 402 is working, avoiding pipe rupture and affecting production. When the mold closing operation is required, the hydraulic cylinder 402 is started, and the hydraulic cylinder 402 drives the upper mold base 403 fixedly connected to it to move downward. The upper mold base 403 supports the upper mold body 404, providing a stable mounting foundation; it also effectively transmits the power from the hydraulic cylinder 402 to the upper mold body 404. In the closed state, the upper mold body 404 engages with the lower mold body 407. Guide grooves 405 are formed around the bottom of the upper mold body 404, and guide posts 406 are slidably connected inside the guide grooves 405. The bottom end of the guide posts 406 is fixedly connected to the lower mold body 407. During mold closing, the upper mold body 404 gradually approaches the lower mold body 407 as the upper mold base 403 moves downward. At this time, the guide grooves 405 slide along the guide posts 406, ensuring precise alignment between the upper mold body 404 and the lower mold body 407, forming the upper part of the closed cavity for injection molding. The lower mold body 407 is located at the bottom end of the guide posts 406, and together with the upper mold body 404, it forms a complete cavity. When molten plastic material is injected into this closed cavity, the plastic gradually fills the cavity and forms the shape of the battery box lower cover. After injection molding is completed, the hydraulic cylinder 402 works in reverse according to the control system command, driving the upper mold base 403 to move upward, thereby lifting the upper mold body 404 upward to realize the mold opening action.

[0024] Furthermore, four sets of guide pillars 406 are provided. The outer ring size of the guide pillars 406 matches the internal size of the guide grooves 405. Through the arrangement of the guide pillars 406, precise guidance is provided for the downward movement of the upper mold body 404 during mold closing, allowing the upper mold body 404 to smoothly slide down along the guide pillars 406 through the guide grooves 405 at its bottom. This ensures accurate alignment between the upper mold body 404 and the lower mold body 407, forming a regular injection cavity. Simultaneously, during mold opening, it also assists in the smooth upward movement of the upper mold body 404, ensuring the smoothness and accuracy of the mold opening action.

[0025] Furthermore, two sets of hydraulic cylinders 402 are symmetrically distributed on the upper mold base 403. The upper mold body 404 and the lower mold body 407 work together. The arrangement of the two sets of hydraulic cylinders 402 on the upper mold base 403 provides more balanced and stable power support during the up-and-down movement of the upper mold base 403. During mold closing, both sets of hydraulic cylinders 402 simultaneously receive commands from the control system and drive the pistons through the pressure of their internal hydraulic oil, collaboratively providing downward power to the upper mold base 403. This ensures that the upper mold base 403 can move downwards smoothly and accurately, achieving precise mold closing with the lower mold body 407.

[0026] Working Principle: The processing table 1, serving as the foundational support platform for the entire mold system, first enters the preparation state. Cooling fans 2, installed on its left and right sides, begin operation, continuously rotating to promote rapid airflow and provide initial heat dissipation for the processing table 1 and its surrounding environment. This prevents localized overheating due to heat accumulation during subsequent operations, which could affect mold performance and product quality. Simultaneously, the indicator light 3 on top of the processing table 1 illuminates, indicating to the operator that the equipment is powered on and ready to begin injection molding. A high-strength corrugated pipe 401 allows the feed pipe to extend when the hydraulic cylinder 402 is operating, preventing pipe rupture and production disruptions. When mold closing is required, the hydraulic cylinder 402 activates, driving the fixedly connected upper mold base 403 downwards. The upper mold base 403 supports the upper mold body 404, providing a stable mounting foundation, and effectively transmits the power from the hydraulic cylinder 402 to the upper mold body 404. In the closed state, the upper mold body 404 engages with the lower mold body 407. The bottom of the upper mold body 404 is provided with guide grooves 405 around its perimeter. Guide pillars 406 are slidably connected inside the guide grooves 405, and the bottom ends of the guide pillars 406 are fixedly connected to the lower mold body 407. During mold closing, the upper mold body 404 gradually approaches the lower mold body 407 as the upper mold base 403 moves downwards. At this time, the guide grooves 405 slide along the guide pillars 406, ensuring precise alignment between the upper mold body 404 and the lower mold body 407, forming the upper part of the closed cavity for injection molding. The lower mold body 407 is located at the bottom end of the guide pillars 406, and together with the upper mold body 404, forms a complete cavity. When molten plastic material is injected into this closed cavity, the plastic gradually fills and shapes the lower cover of the battery box. Furthermore, during the injection molding process, the temperature sensor 501 monitors the temperature inside the molding mechanism 4 in real time and transmits the acquired temperature data to the corresponding control system. When the mold performs injection molding, the large amount of heat brought in by the molten plastic is conducted to the molding mechanism 4, and then transferred to the cooling plate 502. The heat-conducting layer 503 fixedly installed above the cooling plate 502 plays a role in optimizing heat conduction. It can quickly and evenly diffuse the heat absorbed by the cooling plate 502, ensuring that the heat is reasonably distributed in the cooling plate 502 and its surrounding area, so that the coolant can absorb this heat more efficiently. In terms of coolant circulation, the inlet 504 fixedly connected to one side of the cooling plate 502, the first connecting pipe 506 connected to it, the first water pump 509 installed at one end of the first connecting pipe 506, and the cooling tank 511 connected to the other end of the first water pump 509 together constitute the coolant input passage. During operation, the first water pump 509 starts, draws coolant from the cooling tank 511, and steadily delivers the coolant to the inlet 504 of the cooling plate 502 through the first connecting pipe 506, so that the coolant can smoothly enter the flow channel inside the cooling plate 502.Meanwhile, a coolant output path is established by a water outlet 505 fixedly installed on the other side of the cooling plate 502, a second connecting pipe 507 connected to the water outlet 505, and a second water pump 510 installed at one end of the second connecting pipe 507. After the coolant absorbs heat inside the cooling plate 502, the coolant carrying heat flows out from the water outlet 505, is drawn by the second water pump 510 through the second connecting pipe 507, and is then sent back to the cooling tank 511, thus completing the complete circulation path of the coolant between the cooling plate 502 and the cooling tank 511. The control system will precisely regulate the solenoid valve 508 based on the internal temperature of the forming mechanism 4 fed back by the temperature sensor 501. When temperature sensor 501 detects that the internal temperature of the forming mechanism 4 is too high, the control system adjusts the solenoid valve 508 to increase its opening, thereby increasing the flow rate of coolant and allowing the coolant to flow more quickly through the cooling plate 502, accelerating the cooling speed. Conversely, when temperature sensor 501 detects that the internal temperature of the forming mechanism 4 is too low, the control system adjusts the solenoid valve 508 accordingly to decrease its opening, appropriately reducing the flow rate of coolant to maintain a suitable cooling speed and avoid over-cooling that could affect product quality. The water circulation radiator 512, which is fixedly installed inside the cooling tank 511, is a key component ensuring continuous and effective cooling of the coolant. After the coolant carrying heat is returned to the cooling tank 511, the water circulation radiator 512 will use its own heat dissipation mechanism to dissipate the heat in the coolant to the surrounding environment, so that the coolant can be drawn back to a suitable temperature by the first water pump 509 and recycled, continuously providing effective cooling capacity for the cooling plate 502, ensuring that the forming mechanism 4 and the battery box lower cover being formed are uniformly cooled and formed in a suitable temperature environment. Finally, after the battery box lower cover has been cooled and formed in the cavity, the hydraulic cylinder 402 will work in reverse again according to the control system command, driving the upper mold base 403 to move upward, thereby driving the upper mold body 404 to lift upward, realizing the mold opening action.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
