It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see Figs. 1 to 4 This utility model provides a technical solution: a hot pressing molding machine for the research and development of special membranes for hydrogen refueling stations, including a machine body 1, which serves as the main load-bearing structure of the equipment. The machine body 1 has a molding chamber inside, providing a closed and stable working space for the hot pressing molding process of the special membranes. Support legs 19 are fixedly connected to the bottom of the machine body 1. The support legs 19 are made of high-strength metal, which not only provides stable support for the entire machine body 1 but also allows for adjustment of the height of the support legs to accommodate installation surfaces with varying flatness. A hydraulic rod 2 is installed at the top of the molding chamber, serving as the core... The pressure drive component is linked with the hydraulic system inside the machine body 1, and can accurately output the set pressure. The bottom of the hydraulic rod 2 is fixedly connected to the mold block 3, and the bottom of the forming chamber is provided with the mold block 4. The mold block 3 can move up and down reciprocally under the drive of the hydraulic rod 2, while the mold block 4 is fixedly connected to the bottom of the forming chamber. The two cooperate with each other to provide a bearing foundation for the subsequent installation of mold components and the realization of special film hot pressing. A control cabinet 16 is set on one side of the machine body 1. The control cabinet 16 is the control core of the equipment. It integrates a PLC control system and circuit module, which can accurately control the pressure output of the hydraulic rod 2 and the operating parameters in the forming chamber. A display screen 17 is fixedly installed at one end of the control cabinet 16. The display screen 17 is used to display the key parameters of the equipment in real time, which is convenient for operators to monitor intuitively. Buttons 18 are set on both sides of the display screen 17. The buttons 18 are human-machine interaction operation components, which can realize the functions of equipment start and stop, parameter adjustment, and process formula call. Together with the display screen 17, they form a complete operation control unit. Specifically, the equipment is started by pressing the buttons 18 on both sides of the control cabinet 16. The preset special diaphragm R&D process formula is called on the display screen 17, or the pressure value of the hydraulic rod 2 and the molding holding time are manually set. After confirming that the parameters are correct, they are saved. Then, the matching mold components are installed on mold block 1 3 and mold block 2 4 respectively, ensuring that mold block 1 3 is tightly fixed to the bottom of the hydraulic rod 2 and that mold block 2 4 is stably attached to the bottom of the molding chamber. The diaphragm material is then placed flat into the cavity of the fixed mold 6. The run button 18 of the control cabinet 16 is pressed, and the hydraulic rod 2 drives mold block 1 3 to slowly descend. With the guidance of the guide post 7 and the guide sleeve 11, the mold is accurately closed and the set pressure is applied. During the process, the key parameters such as pressure and temperature are monitored in real time through the display screen 17 to avoid abnormal fluctuations. After the preset holding time is reached, the hydraulic rod 2 automatically rises and drives mold block 1 3 to reset. The molding chamber door is opened, and the molded diaphragm is taken out through the handles 14 on both sides of the fixed mold 6. Finally, the mold cavity and molding chamber are cleaned, the power of the control cabinet 16 is turned off, and the status of the machine body 1 and each component is checked to complete a single hot pressing molding operation.

[0016] Secondly, mold block 3, as the core reference component supporting the moving mold 5, has a mold groove 12 inside. The inner wall of mold groove 12 is precisely matched with the outer dimensions of the moving mold 5, ensuring that the moving mold 5 is stably installed inside mold groove 12. This ensures that the moving mold 5 does not shift or shake during the hot pressing process, providing stable upper mold support for the special diaphragm forming. Mold block 4, as the mounting carrier of the fixed mold 6, has a mold groove 23 inside. The depth and flatness of mold groove 23 match the thickness and bottom surface precision of the fixed mold 6, ensuring that the fixed mold 6 is firmly installed in mold groove 23. This ensures that the relative position of the fixed mold 6 and mold block 24 remains constant, preventing displacement under the hot pressing pressure. The outer walls of mold block 3 and mold block 24 have positioning holes 8, and the outer walls of the moving mold 5 and fixed mold 6 have threads. The internal thread of the hole 9 is connected to a bolt 10. Several symmetrically distributed guide posts 7 are fixedly connected to the bottom edge of the moving mold 5. The top of the fixed mold 6 is provided with a guide sleeve 11 corresponding to the guide post 7. The outer wall of the guide post 7 and the inner wall of the guide sleeve 11 are fitted together to form a sliding connection, which can realize real-time and precise guidance during the mold closing process of the moving mold 5 and the fixed mold 6. Handles 14 are provided on both sides of the fixed mold 6. The handles 14 are convenient for operators to hold and exert force when changing the fixed mold 6, cleaning the mold and maintaining the equipment. They can also reduce the collision damage between the fixed mold 6 and the mold block 2 4 during disassembly and assembly, and improve the mold replacement efficiency. The top of the moving mold 5 is fixedly connected to an external interface 15, which can stably connect to external monitoring components to collect the core parameters of the moving mold 5 in the hot pressing process in real time and transmit the data to the control cabinet 16. Specifically, align the moving mold 5 with the mold groove 12 of mold block 3. Since the inner wall of mold groove 12 precisely matches the outer dimensions of the moving mold 5, place the moving mold 5 smoothly and secure it with bolts 10 to ensure that the moving mold 5 does not shift or shake during hot pressing. Then, align the fixed mold 6 with the mold groove 13 of mold block 4. Based on the depth and flatness requirements of mold groove 13, firmly install the fixed mold 6 in the groove to ensure that the relative position of the fixed mold 6 and mold block 4 remains constant and to avoid displacement under pressure. Securely install 5 and 6 through positioning holes 8 and threaded holes 9. Next, connect the external monitoring component to the peripheral interface 15 on the top of the moving mold 5 to ensure that real-time parameters can be transmitted. The material is fed into the control cabinet 16. Then, the mold block 3 is manually pushed to check whether the guide post 7 at the bottom edge of the moving mold 5 is precisely aligned with the guide sleeve 11 at the top of the fixed mold 6, and whether the outer wall of the guide post 7 and the inner wall of the guide sleeve 11 slide smoothly. After the film material is put in, the equipment is started. When the mold is closed, the guide post 7 and the guide sleeve 11 guide the precise mold closing. During the process, the molding status is monitored by the data transmitted through the external interface 15. After molding, the equipment is opened, and the film is removed by holding the handles 14 on both sides of the fixed mold 6 to avoid bumps and damage during disassembly and assembly. Finally, the mold slot 12, mold slot 2 13 and the cavities of the moving mold 5 and the fixed mold 6 are cleaned, and the installation status of each component is checked to complete the single operation.

[0017] When this device is in operation, the equipment is started via buttons 18 on both sides of the control cabinet 16. The preset special diaphragm R&D process formula is displayed on the screen 17, or parameters such as the pressure value of the hydraulic rod 2 and the molding holding time are manually set. After confirming that everything is correct, the settings are saved. Next, the mold is installed. The moving mold 5 is aligned with the mold groove 12 of mold block 3. Because the inner wall of mold groove 12 precisely matches the outer dimensions of the moving mold 5, it is placed smoothly and fixed with bolts 10 to ensure that the moving mold 5 does not shift or shake during hot pressing. Simultaneously, the fixed mold 6 is aligned with the mold groove 13 of mold block 4. Based on the depth and flatness requirements of mold groove 13, the fixed mold 6 is firmly installed in the groove using positioning holes 8 and threaded holes 9, ensuring that the relative position of the fixed mold 6 and mold block 4 remains constant to avoid pressure displacement. Finally, the external monitoring components are connected to the external interface 15 on the top of the moving mold 5 to ensure... The collected parameters can be transmitted to the control cabinet 16, and the mold block 3 is manually pushed to check whether the guide post 7 at the bottom edge of the moving mold 5 is precisely aligned with the guide sleeve 11 at the top of the fixed mold 6 and slides smoothly. Then, the film material is flatly placed into the cavity of the fixed mold 6, and the run button 18 of the control cabinet 16 is pressed. The hydraulic rod 2 drives the mold block 3 to slowly descend. With the guidance of the guide post 7 and the guide sleeve 11, the mold is accurately closed and the set pressure is applied. During the process, the key parameters such as pressure and temperature are monitored in real time through the display screen 17. After the preset pressure holding time is reached, the hydraulic rod 2 automatically rises to drive the mold block 3 to reset. The molding chamber door is opened, and the molded film is taken out by holding the handles 14 on both sides of the fixed mold 6. Finally, the mold cavity, mold groove 12, mold groove 2 and molding chamber are cleaned, the power of the control cabinet 16 is turned off, and the status of the machine body 1 and each component is checked to complete a single hot pressing molding operation.
