During processing, the following procedures are sequentially performed on the surface of the lower die: coating of a release agent, laying of multiple layers of carbon fiber prepreg, mold closing and heating curing (the upper die and the lower die are internally provided with electric heating elements), and cooling and mold opening.

[0040] The terms used in the present application are those general terms currently widely used in the art in consideration of the functions about the present application, but the terms can be changed according to the intention of those skilled in the art, precedents, or new technology in the art. In addition, specific terms can be selected by the applicant, and in this case, the detailed meaning thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meaning of the terms and the overall description of the present application.
[0041] REFERENCE Figures 1-11 The present embodiment provides a molding device for processing carbon fiber composite board, for continuous production of carbon fiber laminated board, comprising an upper die seat component 1, which is provided with an upper punch 41 at the bottom, and the upper punch 41 is provided with a heating element; a lower die seat component 2, which comprises a first lower die seat 21 and a second lower die seat 22 arranged side by side, and the two are driven to alternately enter the processing station directly below the upper die seat component 1 by a translation mechanism 28; wherein the first lower die seat 21 and the second lower die seat 22 each comprise a base 23, and a bottom plate 24 arranged horizontally on the base 23, and the bottom plate 24 is fixedly connected with the translation mechanism 28; an intermediate plate 25 which is detachably mounted on the bottom plate 24, and the moving direction of the intermediate plate 25 is perpendicular to the translation direction of the bottom plate 24; a lower die 42 provided on the intermediate plate 25; the intermediate plate 25 is provided with a first power connection component 26 at the bottom, which is used for on / off control of the heating element in the lower die 42.
[0042] In the present application, continuous production is achieved by alternating operation of the double lower die seat components 2, wherein the upper die seat component 1 serves as a fixed processing unit, the upper punch 41 at the bottom of which is provided with a heating element for heat pressing and curing, and the lower die seat component 2 adopts a parallel arrangement of the first lower die seat 21 and the second lower die seat 22, which are driven to switch workstations by the translation mechanism 28. Each lower die seat adopts a layered design: the base 23 provides support, the bottom plate 24 is fixed with the translation mechanism 28 to realize horizontal movement, and the middle plate 25 can slide vertically to complete quick replacement. The lower concave die 42 installed on the middle plate 25 is used to carry materials, and the built-in heating element is controlled by the first power connection 26 at the bottom of the middle plate 25 and the second power connection 29 on the lower concave die 42.
[0043] When one of the lower die seats is in the processing workstation for heat pressing, the other lower die seat can be moved out for material replacement operation. The quick disassembly and installation of the lower concave die 42 is achieved by the sliding of the middle plate 25, and at the same time, the first power connection 26 on the middle plate 25 automatically completes the power-off protection of the lower concave die 42. This design effectively solves the low efficiency problem caused by serial operation of traditional equipment and realizes parallel operation of processing and material preparation.
[0044] The left and right sides of the base 23 are symmetrically provided with extension tables 27 with flush upper surfaces, and the translation mechanism 28 is provided with two groups of extension tables 27 installed below the two extension tables 27. When one of the lower die seats is in the processing workstation, the other lower die seat is on the extension table 27. The bottom plate 24 of the first lower die seat 21 and the bottom plate 24 of the second lower die seat 22 are fixed by the connecting plate 285, and the lower surface of the bottom plate 24 of the first lower die seat 21 or the second lower die seat 22 slides along the upper surface of the base 23 and the extension table 27.
[0045] The lower die seat component 2 adopts a symmetrical design, wherein the left and right sides of the base 23 are provided with horizontal extensions for supporting the extension tables 27, and the upper surfaces of the two extension tables 27 are flush with the upper surface of the base 23. The translation mechanism 28 adopts a symmetrical double-drive layout, two groups of extension tables 27 are installed below the two extension tables 27, the bottom plates 24 of the first lower die seat 21 and the second lower die seat 22 are connected and fixed by the rigid connecting plate 285 to form an integrated structure. During operation, the translation mechanism 28 drives the bottom plates 24 of the two lower die seats to slide smoothly along the upper surfaces of the base 23 and the extension table 27, ensuring the synchronization and stability of the translation movement. This symmetrical arrangement of the extension table 27 not only provides installation space for the translation mechanism 28, but also serves as a guide reference surface for the sliding of the bottom plate 24, enabling the entire lower die seat system to perform alternating displacement accurately. Further, ball bearings or the like can be provided on the lower surface of the bottom plate 24 or the upper surface of the base 23 and the extension table 27 to reduce friction.
[0046] The translation mechanism 28 includes two sets of chains 281 installed on both sides of the lower surface of each extension table 27, and each chain 281 is provided with sprocket wheels 282 at both ends, wherein the two sprocket wheels 282 on the side close to the base 23 are connected in series by the output shaft of the same motor, and a strip-shaped slot 283 corresponding to the chain 281 is opened on the surface of the extension table 27, and one section of the chain 281 is fixed to the lower surface of the first lower mold base 21 or the second lower mold base 22 through a link plate 284.
[0047] The translation mechanism 28 adopts a double-chain 281 synchronous driving design, and two sets of parallel chains 281 are arranged below the extension table 27 on both sides of the base 23, and each chain 281 is provided with sprocket wheels 282 at both ends, wherein the two sprocket wheels 282 on the side close to the base 23 are coaxially connected through the output shaft of the same motor, so that the motor on each side can control the synchronous movement of the two parallel chains 281 on the same side. A strip-shaped slot is opened on the surface of the extension table 27, and the chain 281 is connected to the lower mold base bottom plate 24 through the slot, and the specific connection mode is that a specific section of the chain 281 is fixed to the lower surface of the lower mold base bottom plate 24 through the link plate 284, and when the motor drives the sprocket wheel 282 to rotate, the chain 281 drives the fixedly connected lower mold base to realize precise translation movement. The symmetrical arrangement of the double-chain 281 system ensures the synchronization and stability of the two lower mold base components 2 during movement.
[0048] The upper surface of the bottom plate 24 is provided with a first limiting sliding groove 241 perpendicular to the moving direction of the lower mold base component 2, and the first limiting sliding groove 241 is arranged in parallel with two, and the lower surface of the middle plate 25 is provided with a plurality of limiting sliding feet 251, each of which slides in the corresponding first limiting sliding groove 241. Three second limiting sliding grooves 252 are opened on the upper surface of the middle plate 25, which are consistent with the moving direction of the lower mold base component 2, and the sliding feet on the lower surface of the lower concave die 42 are detachably installed.
[0049] The positioning guide of the present application adopts a multi-stage sliding groove structure design, wherein two parallel first limiting sliding grooves 241 are machined on the upper surface of the bottom plate 24, and the extension direction is perpendicular to the overall moving direction of the lower mold base component 2, so that the staff can stand on both sides of the production line to quickly switch the middle plate 25 and the lower concave die 42 moved out by the translation mechanism 28, one side introduces new middle plate 25 and lower concave die 42, and the other side exports old middle plate 25 and lower concave die 42, which provides a first way to disassemble the lower concave die 42. A plurality of guide sliding feet are provided on the bottom of the middle plate 25, which are accurately embedded in the first limiting sliding groove 241 of the bottom plate 24, ensuring smooth sliding of the middle plate 25 along the predetermined track during replacement.
[0050] The upper surface of the intermediate plate 25 is provided with three parallel second limiting sliding grooves 252, which are consistent with the translation direction of the lower die seat, facilitating the separate disassembly of the lower concave die 42 from the intermediate plate 25, and providing a second disassembly mode for the lower concave die 42. The bottom of the lower concave die 42 is also provided with detachable positioning sliding feet, which are installed in cooperation with the second limiting sliding grooves 252 of the intermediate plate 25, ensuring the accurate positioning of the lower concave die 42 and facilitating quick disassembly and replacement.
[0051] This multi-level sliding groove guide realizes the disassembly of the lower concave die 42 in multiple ways, so that when one method fails, another can be used to supplement the operation in time, avoiding the impact on production. The first disassembly method requires the lower concave die 42 and the intermediate plate 25 to be disassembled together, which ensures that the connection between the lower concave die 42 and the intermediate plate 25 is always fixed, and only the intermediate plate 25 and the bottom plate 24 are quickly switched, avoiding the wear and tear of the lower concave die 42 caused by frequent switching (since the importance and difficulty of making the lower concave die 42 are higher than those of the intermediate plate 25, the intermediate plate 25 is more easily replaced and accepted), and since its moving direction is perpendicular to the movement direction of the translation mechanism 28, it can provide two positions, realizing the synchronous movement of one side feeding and the other side discharging, improving the work efficiency; the second disassembly method requires the lower concave die 42 to be disassembled quickly, but the lower concave die 42 can only have a single station for feeding and discharging, which requires discharging first and then feeding, which takes longer time than the first method, so as a backup solution, the multi-level guide ensures the position accuracy and stability of each component during the two quick disassembly processes.
[0052] In order to break through the efficiency bottleneck of traditional carbon fiber plate forming equipment, the device adopts a double-station cooperative operation mode. The key to this design is to realize the synchronous feeding and discharging operation of the material - when one side station is installing the intermediate plate 25 and the lower concave die 42, the other side station can complete the disassembly of the old mold group at the same time. This parallel operation mode greatly shortens the production rhythm, but at the same time it also brings new technical challenges: since the lower concave die 42 has built-in heating elements that need to be powered continuously, if the traditional plug-in power connection method is used, not only is the operation cumbersome, but it also offsets the efficiency advantage brought by the double-station design. Therefore, a new power connection method matching the quick disassembly process has been specially developed, specifically: two mounting holes 253 are provided on the intermediate plate 25, corresponding to the two first limiting sliding grooves 241, and a first power connection piece 26 is detachably installed in the mounting hole 253. The upper end of the first power connection piece 26 is located in the middle of the three second limiting sliding grooves 252, and the lower end is in the first limiting sliding groove 241.
[0053] The intermediate plate 25 is provided with two mounting holes 253 corresponding to the first limiting sliding groove 241 of the bottom plate 24, and the first power connecting piece 26 is detachably fixed in the mounting hole 253, with the upper extension segment located in the central channel of the three second limiting sliding grooves 252 of the intermediate plate 25, and the lower part extending into the first limiting sliding groove 241 of the bottom plate 24. This arrangement allows the first power connecting piece 26 to penetrate the upper and lower surfaces of the intermediate plate 25, ensuring the reliability of power supply for the heating element of the lower die 42, and not affecting the relative sliding between the intermediate plate 25 and the bottom plate 24. The detachable feature of the first power connecting piece 26 facilitates maintenance and replacement, and its layout through the intermediate channel ensures precise butt joint of the electrical connection with the lower die 42, while avoiding interference with other sliding groove structures. The entire electrical connection and mechanical guidance cooperate with each other to achieve quick replacement while ensuring electrical safety and operational convenience.
[0054] The first power connecting piece 26 and the second power connecting piece 29 each include a T-shaped shell 261 at the lower end and a column 262 at the upper end, and a pressing foot 263 is arranged on each of the two symmetrical sides of the T-shaped shell 261. The outer end of the pressing foot 263 is arc-shaped, and a spring 264 is arranged for pulling the pressing foot 263 outward. A vertical through hole 265 is arranged inside the T-shaped shell 261 and the column 262, and a power connecting rod 266 is arranged in the through hole 265. The outer wall of the power connecting rod 266 is provided with an inclined groove, and the inner end of the pressing foot 263 is located in the inclined groove for controlling the lifting of the power connecting rod 266. A power connecting piece 267 is arranged in the first limiting sliding groove 241, and the first limiting sliding groove 241 is provided with a diameter-expanded circular cavity 268 at the position where the power connecting piece 267 is arranged. The outer end of the pressing foot 263 is attached to the inner wall of the circular cavity 268. The two power connecting pieces 267 correspond to the neutral line and the live wire, respectively. The lower end of the power connecting rod 266 is in contact with the power connecting piece 267, and the upper end of the power connecting rod 266 is provided with a power connecting port 269. The lower die 42 is also provided with a second power connecting piece 29, and the second power connecting piece 29 of the lower die 42 is inserted into the power connecting port 269.
[0055] The first and second electrical connectors 26 and 29 are mechanically linked and connected electrically. The core components include a T-shaped shell 261 and an upper column 262. The T-shaped shell 261 is symmetrically provided with extendable and retractable extrusion feet 263 on both sides. The outer end of the extrusion feet 263 is provided with a circular arc structure to ensure smooth sliding and is cooperated with a spring 264 to realize automatic reset. The T-shaped shell 261 and the column 262 are internally provided with a vertical channel. An electrical connector rod 266 is movably arranged in the vertical channel. The electrical connector rod 266 and the extrusion feet 263 are connected through a slanted groove to realize lifting control. When the first electrical connector 26 is moved to the position of an electrical connector plate 267, the enlarged circular cavity 268 of the first limiting sliding groove 241 causes the extrusion feet 263 to expand under the action of the spring 264, thereby pushing the electrical connector rod 266 to descend and contact the electrical connector plate 267 in the sliding groove to conduct electricity. When the first electrical connector 26 is moved away from the position, the sliding groove wall compresses the extrusion feet 263 to retract, thereby driving the electrical connector rod 266 to rise and disconnect electricity. The upper end of the electrical connector rod 266 is provided with an electrical connector port 269 which is quickly plugged with the plug of the electrical connector 26. The bottom wall of the electrical connector port 269 is upwardly protruded to contact the lower end of the electrical connector rod 266, thereby realizing reliable power supply of the heating element. The design organically combines mechanical movement and electrical connection to realize quick disassembly and assembly under the condition of live wire while ensuring safety.
[0056] It should be noted that the electrical connectors are arranged on the middle plate 25 and the lower die 42. The lower end of the electrical connector rod 266 of the second electrical connector 29 is plugged into the upper end of the T-shaped shell 261 of the first electrical connector 26 on the middle plate 25, thereby contacting the electrical connector port 269 at the upper end of the electrical connector rod 266 in the T-shaped shell 261 and connecting the entire circuit.
[0057] Specifically, during installation, the first power connecting part 26 of the intermediate plate 25 slides along the first limiting sliding groove 241 together with the limiting sliding foot 251, wherein the T-shaped shell 261 of the first power connecting part 26 has the same cross-sectional area as the limiting sliding foot 251, and the first limiting sliding groove 241 is provided with a downward groove at the lower surface of the position where the power connecting sheet 267 is arranged, and the power connecting sheet 267 is arranged in the groove, so that the power connecting sheet 267 is prevented from being contacted by the limiting sliding foot 251 and the like, safety is ensured, and friction loss is avoided. Meanwhile, the first limiting sliding groove 241 is provided with a circular cavity 268 with an enlarged diameter at the left and right sides of the position where the power connecting sheet 267 is arranged, so that when the first power connecting part 26 is located at the position, the two extrusion feet 263 on the left and right sides of the first power connecting part 26 will be expanded outward under the action of the spring 264 without the limitation of the inner wall of the first limiting sliding groove 241. Thus, the two extrusion feet 263 are synchronously expanded outward at the vertical through hole 265 in the first power connecting part 26, so that the power connecting rod 266 located in the through hole 265 is lowered, and the lower end of the power connecting rod 266 is in contact with the power connecting sheet 267, so that the power connection is realized. Conversely, when the first power connecting part 26 continues to move away from the position of the power connecting sheet 267, the first limiting sliding groove 241 is narrowed due to the disengagement of the circular cavity 268, and the two extrusion feet 263 are recovered, and the two extrusion feet 263 drive the power connecting rod 266 to move upward and break the contact with the power connecting sheet 267, so that the disconnection is realized.
[0058] Please refer to Figures 9-11 Since the two power connecting parts are arranged on the intermediate plate 25 and the lower concave die 42 respectively, the lower end of the first power connecting part 26 of the intermediate plate 25 slides in the first limiting sliding groove 241 and is switched by the circular cavity 268 in the first limiting sliding groove 241, and the lower end of the second power connecting part 29 of the lower concave die 42 slides in the second limiting sliding groove 252 and is switched by the circular cavity 268 arranged in the second limiting sliding groove 252, so that the use mode of the second power connecting part 29 of the lower concave die 42 is the same as that of the first power connecting part 26 of the intermediate plate 25. Only the lower end of the first power connecting part 26 of the intermediate plate 25 is in contact with the power connecting sheet 267, the lower end of the second power connecting part 29 of the lower concave die 42 is inserted into the power connecting port 269 at the upper end of the first power connecting part 26 of the intermediate plate 25 and is in contact with the bottom surface thereof, and the upper end of the second power connecting part 29 of the lower concave die 42 is electrically connected with the internal circuit of the lower concave die 42 as an input power supply.
[0059] The frame body 3 is further provided with a hydraulic part 31 at the upper end of the frame body 3, the hydraulic part 31 is used for controlling the lifting of the upper die seat component 1, and the lower die seat component 2 is installed below the frame body 3.

The lower die seat component 2 is installed at the bottom area in the inner cavity of the frame body 3, and forms an upper and lower corresponding structure layout with the upper die seat component 1. The frame body 3 design provides stable support and guidance for the upper die seat, ensures the working space of the lower die seat translation mechanism 28, and realizes the controllable operation of the upper die seat pressing action through the hydraulic system.
[0061] Referring to Figures 1-8 When the mold pressing forming operation is started, the operator first accurately lays the multilayer carbon fiber prepreg according to the layering order in the cavity of the lower concave die 42 of the second lower die seat 22, starts the two motors of the translation structure, and synchronously drives the two groups of chain wheels 282 through the motor shafts. The first lower die seat 21 and the second lower die seat 22 are synchronously translated in the horizontal direction through the transmission chain 281 meshing with the chain wheels 282. The two lower die seat components 2 are mechanically interconnected through the rigid connecting plate 285, and the respective bases 23 are fixed with the chain 281 through the high-strength link piece 284, so that the motion synchronization is ensured.
[0062] When the chain 281 moves the second lower die seat 22 carrying the material to be processed to the position directly below the upper die seat, the first lower die seat 21 is synchronously moved out, the motor is stopped (automatic stop or displacement sensor triggering is set), at this time the hydraulic part 31 drives the upper die seat to vertically press down, so that the upper punch 41 and the lower concave die 42 of the second lower die seat 22 are accurately matched, after the mold is matched, the electric heating element embedded in the mold is activated, and the laminated material is cured and formed according to the preset temperature curve.
[0063] After the hot pressing and curing are completed and the heating element is turned off, the hydraulic part 31 lifts the upper die seat to open the mold, the motor is reversely driven to drive the chain 281, the second lower die seat 22 of the formed product is moved out of the processing area, and at the same time the first lower die seat 21 is reset to the processing position to prepare for subsequent production, at this time the operator performs the quick replacement operation on the removed second lower die seat 22.
[0064] The operator performs the quick replacement operation on the removed first lower die seat 21 or second lower die seat 22: pushes the middle plate 25 vertically to the movement direction of the chain 281, the extrusion foot 263 at the bottom of the middle plate 25 is extruded and shrunk by the limiting slide groove side wall of the bottom plate 24, the linkage connecting rod 266 is lifted to disengage from the connecting piece 267, and the power supply of the lower concave die 42 is cut off; continuously push the middle plate 25 until the limiting slide foot 251 is completely separated from the slide groove, and at the same time the lower concave die 42 module preloaded with new material is pushed in from the opposite side, so that the old module is forcibly replaced; the removed middle plate 25 and the lower concave die 42 are transported to a special workbench, and the following operations are sequentially performed: taking out the formed product, high-pressure air blowing cleaning of the cavity, spraying high-temperature resistant release agent, and laying the prepreg layer by layer according to the layering design.
[0065] When the first lower die seat 21 finishes the current workpiece processing, the second lower die seat 22 has finished material pre-paving and is on standby. Through the double-station cyclic alternating operation, the parallel operation of material preparation and hot-pressing curing is realized, and the idle of the equipment caused by cleaning / paving in the traditional process is eliminated.
[0066] Finally, it should be pointed out that the above detailed description of the method and device is only an embodiment, and those skilled in the art can modify the embodiment in different ways without departing from the scope of the present application.
