Description

Technical Field

[0001] The utility model relates to the technical field of graphite pole plate forming production, in particular to a cooling system of a graphite pole plate forming die. Background Art

[0002] Graphite plates are core components in hydrogen fuel cell products. Their primary function is to transport gases through the flow field on their surface and to collect and conduct the current, heat, and water generated by the reaction. Depending on the material type, they account for approximately 60%-80% of the product / battery stack weight and approximately 30% of the cost, making them extremely important. Based on specific functional requirements and the acidic electrochemical reaction environment, graphite plates have high requirements for conductivity, airtightness, mechanical properties, and corrosion resistance.

[0003] At present, hot pressing is commonly used to form graphite plates. The preparation process of this method is to mix graphite powder and resin, put them into a hot pressing mold for hot pressing for a certain period of time, and then maintain the pressure until the mold is cooled to obtain a formed plate. There is an important link in this method: the cooling process generally adopts simple water cooling or air cooling, and the cooling water or cooling air passes through the mold. The cooling system of simple water cooling or air cooling structure has many shortcomings: for example, when water cooling, the water volume is large and cannot be accurately controlled, resulting in excessive cooling or insufficient cooling. The air cooling effect cannot be accurately judged, the effect is very poor, and the time is too long. At the same time, the uneven and unreliable cooling effect will make the final graphite plate product insufficient in strength and uneven in thickness. Utility Model Content

[0004] The utility model provides a cooling system for a graphite plate forming die, which solves the problem that the water mist mixture outputted from multiple cooling points in the die is uneven, affecting the uniform cooling of the entire die.

[0005] In order to solve the above technical problems, the technical solutions of the present utility model are as follows:

[0006] The embodiment of the present utility model provides a cooling system for a graphite plate forming mold, comprising:

[0007] Industrial chillers, used to provide cold water at a constant temperature;

[0008] a sprayer connected to the industrial refrigerator, for receiving the cold water and atomizing it into water mist particles;

[0009] A piping system, wherein the sprayer is connected to the mold through the piping system and is used to transport water mist particles to the cooling channel of the mold;

[0010] an atomizing nozzle, provided on the piping system, for spraying water mist particles into the area of ​​the mold that needs to be cooled;

[0014] Furthermore, the mold includes an upper heating plate and a lower heating plate;

[0015] The upper heating plate is located above the mold, and when in use, the upper heating plate abuts against the mold;

[0016] The lower heating plate is located below the mold, and when in use, the lower heating plate abuts against the mold;

[0017] The upper heating plate and the lower heating plate are arranged opposite to each other;

[0018] The upper heating plate and the lower heating plate are both provided with heating plate channels.

[0019] Furthermore, the mold further comprises an upper water cooling plate and a lower water cooling plate;

[0020] The upper water cooling plate is located above the upper heating plate;

[0021] The lower water cooling plate is located below the lower heating plate;

[0022] Cooling channels are provided in the upper water cooling plate and the lower water cooling plate;

[0023] When in use, the cold water enters the cooling channel through the pipeline system to cool the mold. After passing through the cooling channel, the cold water enters the industrial refrigerator through the return water port.

[0024] Furthermore, the sprayer converts cold water into water mist particles with a particle size of 3-10 μm through an atomizing nozzle, thereby increasing the contact area between water and air and absorbing heat energy from the mold.

[0025] Furthermore, the control system includes a solenoid valve and a variable frequency constant pressure water pump;

[0026] When in use, the solenoid valve controls the opening and closing of the atomizing nozzle, and the variable frequency constant pressure water pump controls the supply pressure and flow of cold water.

[0027] Furthermore, the control system is connected to a compressed air pipeline;

[0028] When in use, after cooling is completed, the solenoid valve controls the conversion of the compressed air pipeline, and the compressed air is passed into the heating plate channel to dry the water mist inside the mold.

[0029] Furthermore, the water receiving tray is connected to the drainage groove of the mold, and when in use, is used to drain the accumulated water generated during the cooling process.

[0030] The above solution of the utility model includes at least the following beneficial effects:

[0031] The cooling system of the graphite plate forming mold described in the utility model adopts a water mist mixed cooling method, which combines the advantages of air cooling and water cooling and achieves a more efficient cooling effect. The water mist mixture can be more evenly distributed on the mold surface, thereby quickly taking away heat and improving cooling efficiency. It solves the problem that cooling water and compressed air cannot be fully mixed in the existing cooling method, ensures that the water mist mixture output from multiple cooling points in the mold is uniform, helps to achieve uniform cooling of the entire mold, reduces mold deformation and wear caused by temperature differences, and extends the service life of the mold. The sprayer and industrial refrigerator are independent control system devices, so The cooling process is more controllable, and cooling parameters such as water mist concentration, flow rate and spraying time can be adjusted according to actual needs to achieve precise cooling control. It also improves the flexibility of installation. The nozzle and pipeline can be built into the internal holes of the mold or arranged at the position outside the mold that needs cooling, making cooling more flexible and comprehensive. The water mist cooling method can maximize heating and then rapid cooling, reduce the cooling process, make the cooling curve smoother, and help the product to be fixed and not cracked. At the same time, after cooling, all the water in the internal channels can be automatically taken away, preventing the generation of water vapor during the subsequent heating and pressing process, which affects the product quality.

[0045] like Figures 1 to 2 As shown, the piping system 2 includes pipes built into the internal holes of the mold 1 and pipes arranged at positions outside the mold 1 that need to be cooled.

[0046] In an embodiment of the present invention, the built-in pipes can directly cool the key parts inside the mold, which are often where heat is concentrated and most in need of cooling; the external pipes can cover those areas outside the mold that are easily affected by heat or require special cooling, ensuring that the cooling effect of the entire mold is comprehensive and uniform; by arranging pipes inside and outside the mold, each point that needs cooling can be accurately located to achieve precise control of cooling; the pipe system can be flexibly arranged according to the specific shape of the mold and cooling requirements to ensure maximum cooling effect; the pipe system can ensure that water mist particles are quickly and accurately delivered to every part of the mold that needs cooling, thereby greatly improving cooling efficiency; both the inside and outside of the mold can be evenly cooled, avoiding problems such as mold deformation and cracking caused by uneven cooling; effective cooling can reduce the thermal stress of the mold during operation, reduce thermal fatigue, and thus extend the service life of the mold; uniform cooling helps the graphite plate maintain a stable size and shape during the molding process, improving the quality and consistency of the product; the layout of the pipe system is clear, which facilitates later inspection and maintenance, reducing maintenance difficulty and cost.

[0047] like Figures 1 to 2 As shown, the mold 1 includes an upper heating plate 21 and a lower heating plate 22;

[0048] The upper heating plate 21 is located above the mold 1. When in use, the upper heating plate 21 abuts against the mold 1.

[0049] The lower heating plate 22 is located below the mold 1. When in use, the lower heating plate 22 abuts against the mold 1.

[0050] The upper heating plate 21 and the lower heating plate 22 are arranged opposite to each other;

[0051] Heating plate channels are provided in both the upper heating plate 21 and the lower heating plate 22 .

[0052] In an embodiment of the present invention, the upper heating plate 21 and the lower heating plate 22 are arranged relative to each other, and can apply heat from the upper and lower directions of the mold at the same time to ensure the uniformity of the temperature distribution inside the mold; through the heating plate channel, heat can be transferred to the inside of the mold more quickly, shortening the heating time and improving the heating efficiency; uniform heating helps to reduce the thermal stress inside the mold, reduce the risk of deformation or cracking of the mold due to temperature changes, and thus enhance the durability of the mold; the synergistic effect of the upper heating plate 21 and the lower heating plate 22 can provide the necessary temperature and pressure conditions for the forming of graphite plates, promote the close bonding of graphite particles, and improve the forming quality; the upper heating plate 21 and the lower heating plate 22 can flexibly adjust the heating temperature and heating time to adapt to the forming requirements of graphite plates of different types and specifications, thereby enhancing production flexibility.

[0053] like Figures 1 to 2 As shown, the mold 1 further includes an upper water cooling plate 31 and a lower water cooling plate 32;

[0054] The upper water cooling plate 31 is located above the upper heating plate 21;

[0055] The lower water cooling plate 32 is located below the lower heating plate 22;

[0056] The upper water cooling plate 31 and the lower water cooling plate 32 are both provided with cooling channels;

[0057] When in use, the cold water enters the cooling channel through the pipeline system 2 to cool the mold 1 . After passing through the cooling channel, the cold water enters the industrial refrigerator 5 through the return water port 51 .

[0058] In the embodiment of the present invention, the upper water-cooling plate 31 and the lower water-cooling plate 32 are respectively located above the upper heating plate 21 and below the lower heating plate 22, which can directly cool the heating plate, quickly take away the heat and reduce the temperature of the mold; the design of the cooling channel ensures that the cold water can flow evenly through the water-cooling plate, thereby achieving uniform cooling of the mold and avoiding local overheating or insufficient cooling; since the water-cooling plate is in close contact with the heating plate, the cooling system can quickly respond to changes in the heating plate, adjust the cooling intensity in time, and maintain the stability of the mold temperature; after the cold water passes through the cooling channel, it returns to the industrial refrigerator 5 through the return water port 51 for re-cooling, thereby realizing the recycling of cold water and reducing water resource consumption; the upper water-cooling plate 3 The synergistic effect of the upper and lower water cooling plates 1 and the lower water cooling plate 32, as well as the optimized design of the cooling channel, significantly improves the cooling efficiency and shortens the cooling time of the mold; uniform cooling helps to reduce the thermal stress of the graphite plate during the molding process, avoids deformation and cracking, and thus ensures the quality and consistency of the product; effective cooling can reduce the thermal fatigue of the mold, reduce the wear and damage caused by temperature changes, and thus extend the service life of the mold; the recycling of cold water reduces the waste of water resources, and at the same time the energy efficiency of the industrial refrigerator 5 is also improved, making the entire cooling system more energy-saving and environmentally friendly; the rapid response capability of the cooling system can ensure the stable control of the mold temperature, thereby enhancing the stability of production and improving production efficiency.

[0059] like Figures 1 to 2 As shown, the sprayer 6 converts cold water into water mist particles with a particle size of 3-10 μm through the atomizing nozzle 3, thereby increasing the contact area between water and air and absorbing the heat energy of the mold 1.

[0060] In the embodiment of the present invention, the tiny particle size of the water mist particles greatly increases the contact area between water and air, which helps to more effectively absorb and dissipate the heat energy of the mold 1; the water mist particles with a particle size of 3-10 μm can be more evenly distributed on the mold surface, increasing the heat exchange area between water and the mold, thereby improving the heat exchange efficiency; the atomized water mist particles can more easily penetrate into the tiny gaps and complex structures of the mold, achieving uniform cooling of the mold and avoiding local overheating; due to the large surface area of ​​the water mist particles, the heat exchange with the air is more sufficient, so that less water can be used to achieve the same cooling effect, thereby reducing water resources. consumption; the tiny water mist particles can be evenly distributed on the mold surface, ensuring uniform temperature distribution of the mold during the cooling process, avoiding deformation and cracking caused by thermal stress; uniform cooling helps maintain the dimensional stability and shape accuracy of the graphite plate during the molding process, thereby improving the quality and consistency of the product; due to the efficient cooling capacity of the water mist particles, the required cooling effect can be achieved with less water resources, reducing production costs and water consumption; the design of the sprayer 6 and the atomizing nozzle 3 allows for flexible adjustment of the particle size and distribution of the water mist to adapt to different molds and changes in production requirements, thereby enhancing production flexibility and adaptability;

[0061] The atomizing nozzle can quickly switch to the compressed air blowing mode after completing the water mist particle spraying, so that the graphite particles remaining on the mold surface can be completely cleaned in a short time, thereby greatly shortening the cleaning cycle and improving the overall efficiency of the production line; through the automatic control of the atomizing nozzle and the solenoid valve, the workload of manual cleaning is reduced, the dependence on operators is reduced, and the cleaning process is more convenient and efficient; the graphite particle residue on the mold surface is one of the important factors affecting product quality. The residue may be mixed into the product during the pressing process, resulting in surface defects or performance degradation of the product. Through the precise cleaning of the atomizing nozzle, it can be effectively removed. These residues are removed, thereby ensuring the quality of the next product pressing and improving the product qualification rate and consistency; the atomizing nozzle can achieve a fine atomization effect when spraying water mist particles, which not only helps to better clean the mold surface, but also reduces the waste of water resources. At the same time, when switching to the compressed air purge mode, energy can be saved by optimizing the airflow design; the combined use of the atomizing nozzle and the solenoid valve enhances the reliability and stability of the cleaning equipment. Through the precise control system design, it can ensure that the nozzle accurately switches the working state when needed, reducing the probability of equipment failure and extending the service life of the equipment.

[0062] like Figures 1 to 2 As shown, the control system includes a solenoid valve 7 and a variable frequency constant pressure water pump;

[0063] When in use, the solenoid valve 7 controls the opening and closing of the atomizing nozzle 3, and the variable frequency constant pressure water pump controls the supply pressure and flow of cold water.

[0064] In the embodiment of the present utility model, the solenoid valve 7 can accurately control the opening and closing of the atomizing nozzle 3. When cooling is required, the solenoid valve opens and cold water is sprayed through the atomizing nozzle; when cooling is not required or a pause is required, the solenoid valve closes and the cold water supply is cut off; the solenoid valve has a fast response speed and can realize the switching of the atomizing nozzle in a short time, meeting the rapid cooling demand in the production process; the solenoid valve has good sealing performance and durability, and can ensure that there will be no cold water leakage in the closed state, ensuring the safety and reliability of the system; by accurately controlling the opening and closing of the atomizing nozzle, the solenoid valve can ensure that cooling water mist is provided in time when cooling is required, thereby improving the cooling efficiency; the rapid response and precise control of the solenoid valve help to reduce unnecessary waste of cold water and save water resources; the flexible control of the solenoid valve The cooling operation in the production process is made more flexible and controllable, adapting to different production needs; the variable frequency constant pressure water pump can ensure that the cold water maintains a constant pressure during the supply process, making the particle size and distribution of the water mist particles more uniform; through frequency conversion technology, the flow of the water pump can be adjusted according to actual needs to meet the demand for cold water flow in different cooling stages; the variable frequency constant pressure water pump can adjust the working frequency according to the actual needs of the system, avoid unnecessary energy waste, and reduce energy consumption; the constant pressure supply of cold water can ensure the stability and consistency of the water mist particles, thereby improving the uniformity and stability of cooling; the adjustable flow enables the cooling system to be flexibly adjusted according to the actual temperature and needs of the mold to optimize the cooling effect; the energy-saving characteristics of the variable frequency constant pressure water pump help reduce the energy consumption of the entire cooling system and reduce production costs.

[0065] like Figures 1 to 2 As shown, the control system is connected to a compressed air pipeline;

[0066] When in use, after cooling is completed, the solenoid valve 7 controls the conversion of the compressed air pipeline, and the compressed air is passed into the heating plate channel to dry the water mist inside the mold 1.

[0067] In the embodiment of the present invention, after the cooling is completed, the solenoid valve 7 controls the conversion of the compressed air pipeline to pass the compressed air into the heating plate channel. The high-speed flow of the compressed air can quickly dry the water mist inside the mold 1 to prevent moisture residue. Before the mold needs to be heated again for the next piece of production material to be pressed, the compressed air is first passed in to thoroughly dry the water mist in the heating plate channel, making a good preheating preparation for the subsequent mold heating. By drying the water mist in the heating plate channel, the evaporation of water vapor in the subsequent heating process is effectively prevented. The evaporation of water vapor not only affects the heating efficiency of the mold, but may also cause bubbles and cracks when the product is pressed and formed. The rapid drying capability of compressed air significantly shortens the waiting time of the mold, making the production process more compact and improving production efficiency. By thoroughly drying the water mist in the heating plate channel, the influence of water vapor evaporation on the product pressing and molding effect is eliminated, thereby ensuring the quality and consistency of the product. It avoids corrosion and damage to the mold caused by water vapor during the heating process, which helps to extend the service life of the mold. Since there is no residual water mist in the heating plate channel, the heating process is more efficient and unnecessary energy consumption is reduced. The introduction of compressed air pipelines makes the cooling and heating switching in the production process more flexible and controllable, adapting to different production needs.

[0068] like Figures 1 to 2 As shown, the water receiving tray 4 is connected to the drainage groove of the mold 1 and is used to drain the accumulated water generated during the cooling process when in use.

[0069] In the embodiment of the present invention, the water receiving tray 4 is used to collect the accumulated water discharged from the mold 1 through the drainage groove during the cooling process. After the cooling water circulates inside the mold, it will carry away a large amount of heat and may condense into water droplets or form accumulated water. The water receiving tray can ensure that the accumulated water is effectively collected to prevent it from flowing around; by being connected to the drainage groove of the mold, the water receiving tray 4 ensures unobstructed drainage, so that the accumulated water can flow into the water receiving tray smoothly without affecting the normal use of the mold due to blockage or excessive water accumulation; the existence of the water receiving tray prevents the potential damage of the accumulated water to the mold and surrounding equipment. If there is no water receiving tray to collect the accumulated water, the accumulated water Water may penetrate into the electrical components of the mold, causing short circuits or damage, and may even affect the normal operation of the production line; the water tray effectively drains the accumulated water and keeps the mold dry; the water tray ensures the timely drainage of accumulated water, avoids production interruptions caused by water accumulation, helps to maintain the continuous operation of the production line and improves production efficiency; if the accumulated water is not drained in time, it may form water stains or scale inside the mold, affecting the molding quality and precision of the product; the design of the water tray makes the cleaning of accumulated water simple and convenient. The operator only needs to empty the water tray regularly, without the need for complicated disassembly and cleaning of the mold.

[0070] First, the industrial refrigerator starts according to the preset cooling demand and begins to prepare cold water at a constant temperature; the variable frequency constant pressure water pump starts to transport the constant temperature cold water prepared by the industrial refrigerator to the atomizing nozzle through the pipeline; after the cold water reaches the atomizing nozzle, it is converted into water mist particles with a particle size of 3-10μm through a special high-pressure atomizing nozzle; the solenoid valve opens to control the atomizing nozzle to spray pure water mist to the corresponding parts of the mold that need cooling. The water mist particles diffuse in the air, increasing the contact area between water and air, absorbing the heat of the mold and achieving cooling; at the same time, the branch of the atomizing pipeline is connected to the cooling channel inside the mold, and the water mist directly enters the mold, taking away the heat inside the mold, further improving the cooling efficiency; according to the actual temperature and cooling demand of the mold, the control system adjusts the switch of the solenoid valve, the flow and pressure of the variable frequency constant pressure water pump, and The spray angle and shape of the atomizing nozzle enable precise control of the cooling process; the accumulated water generated during the cooling process will be automatically discharged along the drainage groove of the mold, and the water collection tray set under the cold water plate will collect the accumulated water for subsequent treatment and discharge; after cooling is completed or before the mold needs to be heated again, the control system controls the solenoid valve to switch the pipeline channel and pass compressed air. The compressed air enters the cooling channel inside the mold and the mold surface, blows away the residual water mist, and ensures that there is no moisture inside and on the surface of the mold. After drying, the mold can be heated and prepared for the next round of production; by precisely controlling the generation, injection and discharge process of water mist, efficient mold cooling is achieved, and it also has the functions of water accumulation treatment and mold drying, ensuring the stability and molding effect of the mold during the production process. The work process is highly automated and easy to operate.

[0071] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
