Detailed Implementation

[0013] 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. Example 1

[0014] Please see Figures 1-5 This is the first embodiment of the present invention, which provides a quick-change pressing device for carbon crystal plate production, including... The fixed frame 1 serves as the basic load-bearing structure of the device, providing stable installation support for all components such as the hydraulic cylinder 2 and the recessed seat 6. This ensures that each component maintains a stable relative position during the pressing operation, preventing structural swaying from affecting the pressing accuracy of the carbon crystal plate. Simultaneously, it provides a fixed working frame for the assembly and disassembly of the second mold base 7, making it a core guarantee for the overall structural stability of the device. The fixed frame 1 internally houses the second mold base 7, which is designed for easy assembly and disassembly. Combined with subsequent positioning and stabilizing components, this allows for rapid replacement of the second mold base 7. When producing carbon crystal plates of different specifications, there is no need to modify the entire fixed frame 1; only the second mold base 7 needs to be disassembled and reassembled. This significantly improves the adaptability of the device to different production needs and reduces the complexity of mold changing operations. The positioning and stabilizing assembly includes a recessed seat 6 installed inside the fixed frame 1. The recessed seat 6 serves as the core mounting carrier for the positioning and stabilizing assembly, providing integrated mounting space for components such as the positioning groove 63, the second electric push rod 62, and the first electric push rod 61. This makes the structure of the positioning and stabilizing assembly more compact and avoids positioning deviations caused by the scattered installation of various components. Simultaneously, the fixed connection between the recessed seat 6 and the fixed frame 1 ensures that the positioning and stabilizing assembly will not shift during operation, providing a reliable foundation for the positioning and locking of the second mold base 7. The recessed seat 6 is formed on... The positioning groove 63 is provided at the bottom of the second mold base 7, and a positioning plate 73 can be inserted into the positioning groove 63. The fitting insertion structure of the positioning plate 73 and the positioning groove 63 achieves the initial positioning of the second mold base 7 on the one hand, and on the other hand, after the positioning plate 73 is inserted into the positioning groove 63, it can limit the horizontal displacement of the second mold base 7, prevent the second mold base 7 from shifting horizontally due to force during the pressing operation, and ensure the positional accuracy of the carbon crystal plate during pressing. The fastening plate 72 is provided at the bottom of the second mold base 7, and a receiving groove is opened on the side surface of the fastening plate 72 to accommodate... The slot provides insertion space for the stabilizing block 8. When the stabilizing block 8 is inserted into the receiving slot under the drive of the second electric push rod 62, the fastening plate 72 and the recess 6 can be fixed by the mechanical locking structure, thereby locking the second mold base 7. The opening position of the receiving slot corresponds precisely to the guide hole 64 and the stabilizing block 8 to ensure the smoothness of the locking action. At the same time, the inner wall of the receiving slot can restrict the displacement of the stabilizing block 8 and improve the stability after locking. The guide hole 64 is opened on the side surface of the recess 6, and the second electric push rod 62 is installed in the bottom of the recess 6. The output end of the push rod 62 is connected to a stabilizing block 8 that can pass through the guide hole 64. The stabilizing block 8 can be inserted into the receiving groove. The second electric push rod 62 serves as the power source for the stabilizing block 8. Compared with the traditional manual locking or spring locking structure, the electric drive method can achieve automatic control and complete the extension and retraction of the stabilizing block 8 without manual operation, reducing the intensity of manual labor. At the same time, the output force of the electric push rod is stable and controllable, which can ensure that the locking force of the stabilizing block 8 after being inserted into the receiving groove is consistent, and avoid the second mold base 7 from loosening due to uneven locking force.

[0015] In this embodiment, preferably, it also includes a through-hole 71 opened at the bottom of the second mold base 7, a first electric push rod 61 installed at the bottom of the recess 6, and a top block 610 disposed at the output end of the first electric push rod 61 and able to extend out from the through-hole 71. The through-hole 71 provides an extension channel for the top block 610, so that the top block 610 can extend out from the bottom of the second mold base 7 for easy demolding.

[0016] In this embodiment, preferably, the fastening plate 72 and the second mold base 7 are detachably connected. When the fastening plate 72 is worn, deformed, or the receiving groove is damaged, the fastening plate 72 can be disassembled and replaced separately without replacing the entire second mold base 7, which greatly reduces maintenance costs. The positioning plate 73 and the second mold base 7 are an integral structure.

[0017] In this embodiment, preferably, a hydraulic cylinder 2 is also installed on the top of the fixed frame 1, and the output end of the hydraulic cylinder 2 passes through the fixed frame 1 and is connected to the movable plate 4. The hydraulic cylinder 2 serves as the power source for the pressing operation, and can provide a stable and large pressing force to meet the pressure requirements during the pressing of the carbon crystal plate, ensuring that the materials of each layer of the carbon crystal plate are tightly bonded and improving the structural stability of the carbon crystal plate. At the same time, the hydraulic cylinder 2 is installed on the top of the fixed frame 1 and can drive the movable plate 4 and the first mold base 5 to move through vertical extension and retraction, which meets the vertical pressure requirements of the pressing operation.

[0018] In this embodiment, preferably, a first mold base 5 adapted to the second mold base 7 is installed at the bottom of the movable plate 4. The first mold base 5 and the second mold base 7 are adapted to form a pressing space that matches the specifications of the carbon crystal plate, ensuring that the carbon crystal plate can be accurately positioned between the two mold bases during the pressing operation, avoiding pressing offset. At the same time, the first mold base 5 is installed at the bottom of the movable plate 4 and moves up and down with the movable plate 4 to realize the mold closing and mold opening with the second mold base 7. It is the core working component for completing the pressing of the carbon crystal plate.

[0019] In this embodiment, preferably, the side surface of the first mold base 5 is provided with a fastener 51, and the fastener 51 and the movable plate 4 are detachably connected. When it is necessary to produce carbon crystal plates of different specifications, the first mold base 5 can be quickly replaced by disassembling the fastener 51.

[0020] In this embodiment, preferably, a control cabinet 3 is installed on the side surface of the fixed frame 1 to realize centralized control of electric components such as hydraulic cylinder 2, first electric push rod 61, and second electric push rod 62. The operator can complete the pressing start through the control cabinet 3. Example 2

[0021] Please see Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that: The side surface of the movable plate 4 is provided with a sliding plate 41, and the inner side of the fixed frame 1 is provided with a sliding groove 11 for the sliding plate 41 to slide. The sliding groove 11 provides a sliding track for the sliding plate 41, defines the movement path of the sliding plate 41, and further enhances the guiding effect of the movable plate 4 in raising and lowering. The inner wall of the sliding groove 11 can be smoothed to reduce the resistance when the sliding plate 41 slides. At the same time, the structure of the sliding groove 11 can limit the sliding plate 41 and prevent the movable plate 4 from being damaged by collision due to excessive raising and lowering.

[0022] The working principle and usage process of this utility model are as follows: Align the bottom positioning plate 73 of the new second mold base 7 with the positioning groove 63 of the recessed seat 6 of the fixing frame 1 and insert it. Start the control cabinet 3 to control the second electric push rod 62, push the stabilizing block 8 through the guide hole 64 and insert it into the receiving groove of the fastening plate 72 to complete the fixing of the second mold base 7. If the first mold base 5 needs to be replaced, remove the fastener 51, replace it and then fix it again. The carbon crystal plate raw material is placed into the second mold base 7. The hydraulic cylinder 2 is started through the control cabinet 3. The hydraulic cylinder 2 drives the movable plate 4 so that the bottom first mold base 5 is aligned with the second mold base 7. Hydraulic cylinder 2 continuously applies pressure, and the first mold base 5 and the second mold base 7 close to press the carbon crystal plate together. During the pressing process, the slide groove 11 and the slide plate 41 ensure the stable lifting and lowering of the movable plate 4. After pressing is completed, the hydraulic cylinder 2 drives the movable plate 4 and the first mold base 5 to rise and reset, and the first electric push rod 61 is activated. The top block 610 extends from the through port 71 to lift the carbon crystal plate in the second mold base 7, and the finished product can be taken out.

[0023] Although embodiments of the present invention have been shown and described in detail above, 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.
