[0002] With the continuous development of the new energy vehicle industry, the performance requirements for battery housings are increasing. As a key load-bearing component of the battery system, the battery housing not only needs to protect the battery modules from external impacts and harsh environments, but also needs to meet multiple requirements such as lightweight, high strength, good thermal management, and safety performance, so as to improve the driving range, driving safety, and overall performance of new energy vehicles.

[0003] The existing technology has the following problems:

[0004] 1. The existing traditional battery box in-mold foaming structure on the market is prone to positioning deviation when the mold is closed, which affects the product accuracy, lacks effective buffering, is easy to damage the mold, and the temperature control during the foaming process is unstable.

[0005] 2. Currently available cooling solutions have low efficiency, resulting in inconsistent foaming quality and poor cooling water circulation, which affects production efficiency and product quality. Utility Model Content

[0006] The purpose of this invention is to provide an in-mold foaming structure for a honeycomb aluminum-plastic composite battery box, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an in-mold foaming structure for a honeycomb aluminum-plastic composite battery box, including a support base, a fixing plate fixedly connected to the top of the support base, a support frame fixedly installed on the top of the fixing plate, a cylinder fixedly installed on the top of the support frame, and a support plate fixedly connected to the output end of the cylinder.

[0008] The top of the fixed plate is provided with a lower mold, the bottom of the support plate is fixedly connected with an upper mold, and a cast copper heating plate assembly is fixedly connected to the surface of the support plate near the upper mold. Limiting holes are opened at the four corners of the support plate.

[0009] The present invention further illustrates that a limiting rod is movably connected to the inner surface of the limiting hole, and a rectangular block is provided on the outer wall of the limiting rod near the center.

[0010] Using the above technical solution, the limiting hole slides along the limiting rod to ensure precise mold closing between the upper and lower molds.

[0011] The present invention further illustrates that a buffer spring is fixedly connected to the bottom of the rectangular block, and the bottom of the buffer spring is fixedly connected to the top of the fixed plate.

[0012] Using the above technical solution, the rectangular block on the limiting rod in the solution compresses the buffer spring to buffer the impact force during mold closing.

[0013] The present invention further illustrates that a water storage tank is fixedly connected to one side of the inside of the support base, and a water inlet pipe is provided on the front of the water storage tank.

[0014] Using the above technical solution, cooling water is transported inside the water storage tank through the water inlet pipe, and the water storage tank is used for simple water storage.

[0015] The present invention further describes that a water suction pipe is provided on one side of the water storage tank, a water pump is fixedly installed inside the support base near the center, a conveying pipe is fixedly connected to one side of the water pump, and a water suction pipe is fixedly connected to the other side of the water pump.

[0016] In the above technical solution, during the foaming process, the water pump draws cooling water from the storage tank through the suction pipe and then transports it through the delivery pipeline.

[0017] The present invention further explains that the lower mold has a through groove inside, and a pipe branch is provided inside the through groove. A conveying pipe is fixedly connected to one side of the pipe branch, and a circulating water pipe is fixedly connected to the other side of the pipe branch. The bottom of the circulating water pipe is connected to the inside of the water storage tank.

[0018] Using the above technical solution, the cooling water flows in the pipe branches to cool the lower mold and remove the heat generated by foaming. Then the cooling water flows back to the storage tank through the circulating water pipe, realizing the recycling of cooling water.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0020] This utility model provides an in-mold foaming structure for a honeycomb aluminum-plastic composite battery box. By setting a limiting hole on the support plate, which cooperates with a limiting rod on the fixed plate, the in-mold foaming structure operates as follows: When the cylinder is activated, its output end drives the support plate downwards. Since the bottom of the support plate is connected to the upper mold, and the fixed plate has a lower mold, the limiting hole slides along the limiting rod during the descent of the support plate, achieving precise positioning of the upper and lower molds and ensuring the accuracy and stability of the foaming process. Simultaneously, the rectangular block and buffer spring structure on the limiting rod effectively absorb the impact force generated during mold closing, protecting the mold and equipment and extending its service life. After mold closing, the cast copper heating plate assembly starts working, heating the mold and bringing the foaming material inside to a suitable foaming temperature, meeting the user's usage requirements.

[0021] This utility model provides an in-mold foaming structure for a honeycomb aluminum-plastic composite battery box. By incorporating a water storage tank, a water pump, a delivery pipe, and a circulation pipe, a highly efficient cooling system is constructed. During the foaming process, the water pump draws cooling water from the storage tank through the suction pipe and delivers it to a branch pipe in the internal groove of the lower mold via the delivery pipe. The cooling water flows through the branch pipe, cooling the lower mold and carrying away the heat generated during foaming. The cooling water then flows back to the storage tank via the circulation pipe, achieving the recycling of cooling water. This design not only improves cooling efficiency and reduces energy consumption but also helps control the foaming temperature, improves product quality, and meets the user's operational needs.

[0029] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-5 The present invention provides a technical solution: an in-mold foaming structure for a honeycomb aluminum-plastic composite battery box, including a support base 1, a fixing plate 2 fixedly connected to the top of the support base 1, a support frame 3 fixedly installed on the top of the fixing plate 2, a cylinder 4 fixedly installed on the top of the support frame 3, and a support plate 5 fixedly connected to the output end of the cylinder 4.

[0031] The top of the fixed plate 2 is provided with a lower mold 6, the bottom of the support plate 5 is fixedly connected with an upper mold 7, the surface of the support plate 5 is fixedly connected with a cast copper heating plate assembly 8 near the upper mold 7, and limit holes 9 are opened at the four corners of the support plate 5.

[0032] In this embodiment, when the in-mold foaming structure of the honeycomb aluminum-plastic composite battery box is working, the cylinder 4 is started, and its output end drives the support plate 5 to move downward. Since the bottom of the support plate 5 is connected to the upper mold 7 and the lower mold 6 is set on the fixed plate 2, during the descent of the support plate 5, the limiting hole 9 slides along the limiting rod 10 to ensure that the upper mold 7 and the lower mold 6 are accurately closed. At the same time, the rectangular block 11 on the limiting rod 10 compresses the buffer spring 12 to buffer the impact force during mold closing. After the mold is closed, the cast copper heating plate assembly 8 starts to work to heat the mold and make the foaming material in the mold reach a suitable foaming temperature.

[0033] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a limiting rod 10 is movably connected to the inner surface of the limiting hole 9, a rectangular block 11 is provided near the middle of the outer wall of the limiting rod 10, a buffer spring 12 is fixedly connected to the bottom of the rectangular block 11, and the bottom of the buffer spring 12 is fixedly connected to the top of the fixing plate 2, a water storage tank 13 is fixedly connected to one side of the inner side of the support base 1, and a water inlet pipe 14 is provided on the front of the water storage tank 13.

[0034] In this embodiment, the limiting hole 9 slides along the limiting rod 10 to ensure that the upper mold 7 and the lower mold 6 are accurately closed. The rectangular block 11 on the limiting rod 10 compresses the buffer spring 12 to buffer the impact force during mold closing. Cooling water is transported inside the water storage tank 13 through the water inlet pipe 14, and simple water storage is carried out through the water storage tank 13.

[0035] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a water suction pipe 15 is provided on one side of the water storage tank 13, a water pump 16 is fixedly installed near the middle inside the support base 1, a conveying pipe 17 is fixedly connected to one side of the water pump 16, and a water suction pipe 15 is fixedly connected to the other side of the water pump 16. A through groove 18 is opened inside the lower mold 6, a pipe branch 19 is provided inside the through groove 18, a conveying pipe 17 is fixedly connected to one side of the pipe branch 19, a circulating water pipe 20 is fixedly connected to the other side of the pipe branch 19, and the bottom of the circulating water pipe 20 is connected to the inside of the water storage tank 13.

[0036] In this embodiment, during the foaming process, the water pump 16 draws cooling water from the water storage tank 13 through the suction pipe 15 and transports it through the delivery pipe 17. The cooling water flows in the pipe branch 19 to cool the lower mold 6 and remove the heat generated by foaming. Afterward, the cooling water flows back to the water storage tank 13 through the circulating water pipe 20, realizing the recycling of cooling water.

[0037] like Figure 1-5 As shown, when the user needs to use it, the foaming structure inside the honeycomb aluminum-plastic composite battery box works. Cylinder 4 starts, and its output drives the support plate 5 downwards. Since the bottom of the support plate 5 is connected to the upper mold 7, and the lower mold 6 is set on the fixed plate 2, during the descent of the support plate 5, the limiting hole 9 slides along the limiting rod 10 to ensure precise mold closing between the upper mold 7 and the lower mold 6. Simultaneously, the rectangular block 11 on the limiting rod 10 compresses the buffer spring 12 to buffer the impact force during mold closing. After mold closing, the cast copper heating plate assembly 8 starts working to heat the mold, allowing the foaming material inside the mold to reach a suitable foaming temperature. During the foaming process, the water pump 16 pumps water through the suction pipe... Cooling water is drawn from the water storage tank 13 and transported through the conveying pipe 17 to the pipe branch 19 in the through groove 18 inside the lower mold 6. The cooling water flows in the pipe branch 19 to cool the lower mold 6 and remove the heat generated by foaming. Afterward, the cooling water flows back to the water storage tank 13 through the circulating water pipe 20, realizing the recycling of cooling water. This design not only improves cooling efficiency and reduces energy consumption, but also helps to control the foaming temperature and improve product quality. After foaming is completed, the output end of the cylinder 4 drives the support plate 5 to rise, the upper mold 7 separates from the lower mold 6, and the formed honeycomb aluminum-plastic composite battery box is taken out, completing one foaming process.
