[0001] This invention relates to the field of injection molding technology, specifically to an integrated injection molding device for capacitor housings in new energy vehicles. Background Technology

The advantage is that the injection molding device provided in this application helps improve product quality.

[0003] In the aforementioned patents or prior art, the repeated injection molding process requires two steps: preheating the mold for injection and cooling and demolding. This process consumes a lot of energy, which is relatively wasteful, and direct demolding can easily cause adhesion and damage. Summary of the Invention

[0004] The problem this invention aims to solve is that frequent heating and cooling lead to energy waste, and direct demolding easily causes damage.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an integrated injection molding device for capacitor shells of new energy vehicles, including a cabinet, an upper module is provided inside the cabinet, an upper mold is provided at the bottom of the upper module, a plurality of push plates are arranged in an array on the top of the inner wall of the upper mold, and a plurality of supports are arranged in an array on the top of the plurality of push plates.

[0006] Preferably, the bracket has sliders on both sides, springs at the bottom of the sliders, sealing strips on both sides of the push plate, a hot water pipe on the top of the push plate, a cold water pipe on one side of the hot water pipe, and both the cold water pipe and the hot water pipe are compatible with the bracket.

[0007] Preferably, a cold water tank is provided on one side of the front of the cabinet, the bottom of which is fixedly connected to one end of a cold water pipe, and a hot water tank is provided on one side of the cold water tank, the bottom of which is fixedly connected to one end of a hot water pipe, and the top of which is fixedly connected to the other ends of the cold water pipe and the hot water pipe.

[0008] Preferably, the upper mold has fixing brackets on both sides of its bottom, a lower mold at its bottom, and fixing grooves on both sides of its top, with both fixing brackets fitting into the fixing grooves.

[0009] Preferably, the top of the upper mold is provided with an injection port.

[0010] Preferably, the bottom of the lower mold is provided with a lower module, and the top of the lower module is provided with guide pillars at the four corners of the top. The tops of the four guide pillars all penetrate the bottom of the upper module and extend to the outside.

[0011] Preferably, the top of the upper module is provided with an injection tube, the bottom of which penetrates the top of the upper module and extends to the outside, and the bottom of the injection tube is adapted to the injection port.

[0012] Preferably, a feed inlet is provided on one side of the top of the cabinet.

[0013] Preferably, the push plate is made of a metal with high thermal conductivity, and the cold water pipe and hot water pipe are both made of high-temperature resistant elastic rubber.

[0014] Preferably, the hot water tank has pressurization and heat preservation effects.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) Energy saving and high efficiency are among the core advantages of this device. By setting up a dual-tank structure with a cold water tank and a hot water tank, a closed-loop cooling water circulation and heat recovery system is realized. During the mold cooling stage, cold water flows from the cold water tank through the cold water pipe into the mold, absorbs heat and heats up. This heated cooling water is then recycled to the hot water tank for storage and can be further heated or kept at a constant temperature as needed. Before the start of the next injection cycle, the recycled and stored warm water can be directly used for mold preheating, which significantly reduces energy waste in the repeated heating and cooling process and improves the heat utilization efficiency of the entire system. This alternating and cyclical mode of hot and cold water not only reduces the dependence on external cooling and heating resources, but also effectively reduces equipment operating costs and environmental heat load. The cold water pipe and hot water pipe are made of high-temperature resistant elastic rubber material, which has good thermal stability and pressure resistance. It can work stably for a long time in the high-temperature and high-pressure injection environment, avoiding media leakage and heat loss caused by pipe aging or deformation, and further enhancing the reliability and energy efficiency of the system. Through the above structural design and material optimization, the device achieves high efficiency and energy saving while also taking into account process stability and equipment durability. It is suitable for mass production of precision components such as capacitor shells for new energy vehicles, which have high requirements for energy consumption control and molding quality.

[0016] (2) Improve demolding quality and reduce product loss. The push plate is designed in combination with cold water pipe and hot water pipe. After cooling and solidification, the push plate is pushed by the pressure expansion of the cold water pipe to achieve a smooth and uniform demolding action. Compared with the traditional mechanical ejection method, the pushing force is gentler. Since the physical principle of water pipe expansion is stage expansion, the demolding process is a gradual demolding, avoiding product adhesion or damage that may be caused by the traditional mechanical ejection method. The push plate is equipped with sealing strips on both sides to ensure the sealing of the cooling / heating medium flow and improve the stability of the demolding process.

[0021] like Figures 1 to 13 As shown, the present invention provides an integrated injection molding device for capacitor shells of new energy vehicles, including a cabinet 20. An upper module 1 is arranged inside the cabinet 20. An upper mold 4 is arranged at the bottom of the upper module 1. Several push plates 9 are arranged in an array on the top of the inner wall of the upper mold 4. Several supports 10 are arranged in an array on the top of the push plates 9.

[0022] Both sides of the bracket 10 are provided with sliders 11, and the bottom of each slider 11 is provided with a spring 12. Both sides of the push plate 9 are provided with sealing strips 16. The top of the push plate 9 is provided with a hot water pipe 8, and a cold water pipe 7 is provided on one side of the hot water pipe 8. Both the cold water pipe 7 and the hot water pipe 8 are compatible with the bracket 10.

[0023] A cold water tank 17 is installed on one side of the front of the cabinet 20. The bottom of the cold water tank 17 is fixedly connected to one end of the cold water pipe 7. A hot water tank 18 is installed on one side of the cold water tank 17. The bottom of the hot water tank 18 is fixedly connected to one end of the hot water pipe 8. The top of the hot water tank 18 is fixedly connected to the other end of the cold water pipe 7 and the hot water pipe 8.

[0024] The upper mold 4 has fixing brackets 13 on both sides of its bottom. The lower mold 5 is located at the bottom of the upper mold 4. The lower mold 5 has fixing grooves 14 on both sides of its top. Both fixing brackets 13 are adapted to the fixing grooves 14.

[0025] An injection port 6 is provided on the top of the upper mold 4.

[0026] The bottom of the lower mold 5 is provided with a lower mold 2. The four corners of the top of the lower mold 2 are provided with guide pillars 3. The tops of the four guide pillars 3 all penetrate the bottom of the upper mold 1 and extend to the outside.

[0027] The top of the upper module 1 is provided with an injection tube 15. The bottom of the injection tube 15 passes through the top of the upper module 1 and extends to the outside. The bottom of the injection tube 15 is adapted to the injection port 6.

[0028] A feed inlet 19 is provided on one side of the top of the cabinet 20.

[0029] The push plate 9 is made of metal with high thermal conductivity, while the cold water pipe 7 and the hot water pipe 8 are both made of high-temperature resistant elastic rubber.

[0030] Hot water tank 18 has pressurization and heat preservation effects.

[0031] The working principle and usage process of this invention are as follows: Upon first use, the upper mold assembly 1 and the lower mold assembly 2 are heated. After the plastic granules melt, they are injected into the injection port 6 of the upper mold 4 under pressure through the injection pipe 15. Subsequently, a solidification operation is performed between the upper mold 4 and the lower mold 5. Cooling water in the cold water tank 17 flows through the cold water pipe 7 through the mold for cooling and solidification. Then, the cooling water that has been heated after cooling is injected into the hot water tank 18 for heat preservation and storage, while also allowing for heating. When demolding is required after cooling is complete, the valve at the top of the hot water tank 18 is closed, allowing the cold water in the cold water pipe 7 to continue flowing. The pressurization of the water causes the cold water pipe 7 to expand. During the expansion process, the push plate 9 pushes the sliders 11 on both sides of the top support 10 to move vertically downward along the groove opened in the upper mold 4, thereby pushing the protective shell solidified in the upper mold 4 to be demolded. When the injection molding operation is repeated, the mold is preheated by the cooling water in the hot water tank 18 after cooling, so that the mold heats up more quickly and reduces the energy consumption of the mold heating system. After the mold is heated, the cold water pipe and hot water pipe inside are heated and flow back to the hot water tank 18 for storage, further reducing heat loss.
