Description

Technical Field

[0001] This utility model relates to the field of carbon fiber vehicle frame technology, and in particular to a carbon fiber vehicle frame one-piece molding processing device. Background Technology

[0002] Currently, in the field of carbon fiber frame processing, hydraulic hot pressing molding technology is often used to form the frame. However, in traditional processing equipment, when the lower mold slides and adjusts its position on the base, there is a lack of a stable limiting structure, which makes the mold prone to displacement. This displacement will reduce the mold closing accuracy of the upper and lower molds, resulting in dimensional deviations after the carbon fiber frame is formed. This affects the structural strength and assembly compatibility of the frame, and increases the cost and time of subsequent correction processes.

[0003] For example, the carbon fiber thermoforming machine with patent publication number "CN221848063U" uses air boxes installed on both sides of the hot press platform at the top of the base. Inside each air box is an exhaust fan and a filter cotton plate. During operation, the exhaust fan draws in the fumes generated during the carbon fiber thermoforming process. The fumes are then filtered through the filter cotton plate before being discharged, effectively solving the problems of traditional devices lacking smoke removal capabilities and the harmful substances in the fumes posing a health risk to workers.

[0004] However, the mold and hot press table in the above patent adopt a fixed connection design. When it is necessary to process carbon fiber frames of different specifications and change the mold, it is necessary to disassemble multiple sets of fixed connecting parts between the mold and the hot press table. During the disassembly process, it is also necessary to avoid damaging the heating components on the surface of the hot press table. The operation is difficult and time-consuming, making it difficult for the device to quickly adapt to the processing needs of carbon fiber frames of different specifications, reducing the flexibility and adaptability in the production process. Utility Model Content

[0005] The purpose of this invention is to provide a carbon fiber frame integral molding processing device, which solves the problem that in the prior art, the mold and the hot press table are fixedly connected. When different specifications of carbon fiber frames need to be processed and the mold needs to be changed, multiple sets of fixed connecting parts between the mold and the hot press table must be disassembled first. During the disassembly process, it is also necessary to avoid damaging the heating components on the surface of the hot press table. The operation is difficult and time-consuming, which makes it difficult for the device to quickly adapt to the processing needs of different specifications of carbon fiber frames, reducing the flexibility and adaptability in the production process.

[0006] To achieve the above objectives, this utility model provides a carbon fiber frame integral molding processing device, including a base, a molding mechanism for thermoforming the carbon fiber frame is provided on the upper part of the base, a limiting mechanism is provided on one side of the base, the limiting mechanism includes a connecting frame and a limiting block, the connecting frame is slidably connected to both sides of the base, and the limiting block is slidably connected to the inner wall surface of the connecting frame.

[0007] The base has a lower mold slidably connected to its inner wall surface, a connecting frame fixedly installed on one side of the lower mold, and a support column fixedly installed on the upper surface of the base.

[0008] The support column has a mounting plate fixedly installed at one end, a hydraulic rod fixedly installed on the upper surface of the mounting plate, the hydraulic rod passing through the mounting plate, and a connecting rod fixedly installed at one end of the hydraulic rod.

[0009] A heating plate is fixedly installed at the top of the inner wall of the connecting rod, and an upper mold is slidably connected to both sides of the inner wall of the connecting rod. The upper mold is fixedly connected to the surface of the inner wall of the connecting rod by bolts.

[0010] The base has a mounting box fixedly installed on one side, a gear rotatably connected to one side of the mounting box, and a rack slidably connected to one side of the inner wall of the mounting box, with the rack meshing with the gear.

[0011] The gear has a rotating shaft fixedly installed at one end, the rotating shaft passes through one side of the mounting box and is rotatably connected to one side of the mounting box, and a connecting block is fixedly installed on one side of the rack.

[0012] A spring is fixedly installed on one side of the connecting block, and the other end of the spring is fixedly connected to one side of the inner wall of the mounting box. An mounting rod is fixedly installed on one side of the rack, and the limiting block is fixedly installed on one side of the mounting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the rotating shaft of the limiting mechanism drives the gear to rotate, and the gear meshes with the rack to drive the mounting rod and the limiting block to move. Combined with the elastic reset effect of the spring, the position of the limiting block can be quickly adjusted, achieving convenient limiting and unlocking of the lower mold. When the lower mold needs to be replaced, simply rotating the rotating shaft in the opposite direction releases the limiting mechanism, allowing the old mold to be directly slid off and replaced with the new mold. No other auxiliary parts need to be disassembled, simplifying the mold replacement process and saving replacement time. 2. In this utility model, the upper mold and connecting rod of the forming mechanism are detachably connected by bolts, and the inner walls of the connecting rod have a sliding structure on both sides. When replacing the upper mold, only the fixing bolts need to be unscrewed to remove the old upper mold along the sliding direction and install the new upper mold, without disassembling and adjusting core components such as hydraulic rods and heating plates. At the same time, the lower mold and the base are slidably connected, and with the quick-limiting function of the limiting mechanism, the upper and lower molds can be quickly replaced and accurately positioned, enabling the device to quickly adapt to the processing requirements of carbon fiber frames of different specifications, improving production flexibility and processing efficiency.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1 - Figure 5As shown, the carbon fiber frame integral molding processing device includes a base 1, a molding mechanism 2 for thermoforming the carbon fiber frame is provided on the top of the base 1, and a limiting mechanism 3 is provided on one side of the base 1. The limiting mechanism 3 includes a connecting frame 302 and a limiting block 309. The connecting frame 302 is slidably connected to both sides of the base 1, and the limiting block 309 is slidably connected to the inner wall surface of the connecting frame 302. The base 1 serves as the basic load-bearing structure of the device, providing an installation and operating reference for the molding mechanism 2 and the limiting mechanism 3. The molding mechanism 2 uses the combined action of heating and pressurization to solidify the carbon fiber raw material into a frame within the mold. In the limiting mechanism 3, the connecting frame 302 can slide along both sides of the base 1 to adapt to the position adjustment of the lower mold 201. The limiting block 309 slides on the inner wall of the connecting frame 302 and adheres to the side wall of the lower mold 201 to achieve positioning constraint and prevent mold offset. The beneficial effect of this design is that it clarifies the collaborative layout of the molding mechanism 2 and the limiting mechanism 3, avoiding molding deviation caused by the separation of processing and positioning from the overall structure. The sliding design of the connecting frame 302 and the limiting block 309 breaks the limitations of traditional fixed limiting, can adapt to lower molds 201 of different specifications without replacing the entire set of limiting components, reducing adaptation costs. At the same time, the positioning method of the limiting block 309 close to the processing area is more accurate than indirect limiting, improving mold closing accuracy. A lower mold 201 is slidably connected to the inner wall surface of the base 1, a connecting frame 302 is fixedly installed on one side of the lower mold 201, and a support column 202 is fixedly installed on the upper surface of the base 1. The lower mold 201 slides along the inner wall of the base 1 to switch between picking up parts, loading materials, and processing. The connecting frame 302 is fixedly connected to the lower mold 201. When the lower mold 201 slides, the connecting frame 302 moves synchronously to ensure that the limiting mechanism 3 always maintains a relatively fixed position with the lower mold 201. The support column 202 is vertically fixed on the upper surface of the base 1 to provide stable support for the upper mounting plate 203 and the pressurizing components of the forming mechanism 2, preventing the structure from sinking during pressurization. The beneficial effects of this design are that the sliding design of the lower mold 201 replaces the traditional fixed mold and manual handling of raw materials, reducing the physical exertion of operators and improving operating efficiency. The synchronous movement of the connecting frame 302 and the lower mold 201 does not require recalibrating the limiting mechanism 3 after adjusting the mold position, avoiding the waste of time for secondary calibration and ensuring consistent limiting accuracy for each processing. The support column 202 distributes the weight load of the forming mechanism 2, preventing the base 1 from deforming due to excessive local stress and extending the overall service life of the device. A mounting plate 203 is fixedly installed at one end of the support column 202. A hydraulic rod 204 is fixedly installed on the upper surface of the mounting plate 203. The hydraulic rod 204 passes through the mounting plate 203. A connecting rod 205 is fixedly installed at one end of the hydraulic rod 204.Mounting plate 203 forms a stable frame structure with base 1 through support column 202, serving as the mounting carrier for hydraulic rod 204. When energized, hydraulic rod 204 generates axial extension force. The design of penetrating mounting plate 203 ensures that the extension direction is perpendicular to the plane of base 1. Connecting rod 205 connects hydraulic rod 204 to upper mold 207, transmitting the extension force to upper mold 207 to achieve the cycle of downward mold closing and upward mold opening. The beneficial effects of this design are that hydraulic rod 204 provides uniform and adjustable pressure output, which, compared to pneumatic or manual pressurization, can accurately match the molding pressure requirements of carbon fiber frames of different thicknesses, avoiding uneven frame density caused by pressure fluctuations. The frame structure formed by mounting plate 203 and support column 202 limits the radial displacement of hydraulic rod 204 during extension and retraction, ensuring that upper mold 207 always moves in the vertical direction, improving mold alignment. Connecting rod 205 directly transmits force, reducing power loss, while avoiding increased failure points due to indirect transmission from multiple components, thus reducing equipment maintenance frequency. A heating plate 206 is fixedly installed on the top of the inner wall of the connecting rod 205, and an upper mold 207 is slidably connected to both sides of the inner wall of the connecting rod 205. The upper mold 207 is fixedly connected to the inner wall surface of the connecting rod 205 by bolts. When the heating plate 206 is powered on, it generates heat, which is transferred to the upper mold 207 through the inner wall of the connecting rod 205. This allows the upper mold 207 to reach the temperature required for carbon fiber molding and works in conjunction with the lower mold 201 to heat and solidify the raw material. The sliding structure on both sides of the inner wall of the connecting rod 205 provides a guide for the movement of the upper mold 207. The bolt fixing method allows for quick disassembly and assembly of the upper mold 207. When replacing it, simply unscrew the bolts to remove the old mold along the sliding structure and install the new mold. The beneficial effects of this design are that the close heat transfer between the heating plate 206 and the upper mold 207 reduces heat loss, ensures that the temperature of the upper mold 207 is uniform and stable, and avoids frame molding quality problems caused by uneven temperature. The sliding and bolt fixing design of the upper mold 207 simplifies the replacement process, significantly shortens the mold replacement time compared to traditional complex connecting parts, and improves the processing switching efficiency of different frame specifications. At the same time, the bolt fixing ensures that the upper mold 207 is firmly installed, preventing the mold from loosening during processing and affecting the molding accuracy.

[0023] Please see Figure 1 - Figure 5As shown, a mounting box 301 is fixedly installed on one side of the base 1, a gear 303 is rotatably connected to one side of the mounting box 301, and a rack 304 is slidably connected to one side of the inner wall of the mounting box 301, with the rack 304 meshing with the gear 303. Mounting box 301 provides mounting and protective space for gear 303 and rack 304, preventing external impurities from affecting transmission accuracy. When gear 303 rotates, it drives rack 304 to slide along the inner wall of mounting box 301 through meshing, converting the rotational motion of gear 303 into linear motion of rack 304, providing a power transmission basis for subsequent position adjustment of limit block 309. The beneficial effects of this design are that the meshing transmission of gear 303 and rack 304 has high precision characteristics, ensuring that the displacement adjustment of limit block 309 is accurate and controllable, avoiding limit deviation caused by transmission error. The protective function of mounting box 301 extends the service life of gear 303 and rack 304, reduces transmission failure caused by impurities, and the transmission method of converting rotational motion into linear motion makes it easier for operators to indirectly control the position of limit block 309 by rotating gear 303, reducing the difficulty of operation. A rotating shaft 305 is fixedly installed at one end of the gear 303. The rotating shaft 305 passes through one side of the mounting box 301 and is rotatably connected to one side of the mounting box 301. A connecting block 306 is fixedly installed on one side of the rack 304. The operator rotates the rotating shaft 305 that passes through the mounting box 301, causing the gear 303 to rotate synchronously, which in turn drives the rack 304 to slide. The connecting block 306 is fixed to one side of the rack 304, serving as the connection medium between the rack 304 and the subsequent spring 307, so that the spring 307 can act stably on the rack 304. The beneficial effects of this design are that the setting of the rotating shaft 305 provides the operator with a convenient point of force application, which is less effort than directly rotating the gear 303. The rotational connection between the rotating shaft 305 and the mounting box 301 ensures smooth rotation and reduces operating resistance. The connecting block 306 ensures that the spring 307 and the rack 304 are firmly connected, preventing the spring 307 from falling off and causing the limiting mechanism 3 to fail. At the same time, the connecting block 306 can disperse the force of the spring 307, preventing the rack 304 from being deformed due to excessive local stress, and ensuring transmission stability. A spring 307 is fixedly installed on one side of the connecting block 306, and the other end of the spring 307 is fixedly connected to one side of the inner wall of the mounting box 301. An mounting rod 308 is fixedly installed on one side of the rack 304, and a limiting block 309 is fixedly installed on one side of the mounting rod 308.In its natural state, spring 307 pulls rack 304 via connecting block 306, causing rack 304 to drive mounting rod 308 to adhere to the side wall of lower mold 201 with limit block 309, achieving continuous limiting. When it is necessary to release the limit, rotating shaft 305 drives gear 303 to rotate, causing rack 304 to slide against the elastic force of spring 307, thereby causing limit block 309 to disengage from lower mold 201. Mounting rod 308 extends the force arm of rack 304, ensuring that limit block 309 accurately acts on the limiting area of ​​lower mold 201. The beneficial effects of this design are that the elastic force of the spring 307 keeps the limiting block 309 in close contact with the lower mold 201 at all times, avoiding loosening of the limit due to processing vibration and improving the stability of the limit. The setting of the mounting rod 308 makes the position of the limiting block 309 adapt to the structure of the lower mold 201, and precise limiting can be achieved without adjusting the position of the rack 304, simplifying the structural design. At the same time, the limit can be released by overcoming the elastic force of the spring 307, making the operation convenient and requiring no disassembly of any components, further improving the efficiency of mold replacement.

[0024] Working principle: When this device is needed, the first step is to replace the mold according to the specific specifications of the frame to be processed. When replacing the upper mold 207, the operator uses a wrench to unscrew the bolts that fix the upper mold 207 on the inner wall of the connecting rod 205. At this time, the upper mold 207 loses its fixed constraint and can be smoothly pulled out along the sliding rails on both sides of the inner wall of the connecting rod 205. Then, take the new upper mold 207 that is compatible with the frame to be processed, push it into the designated position on the inner wall of the connecting rod 205 along the sliding rail, and after ensuring that the mold is accurately positioned, tighten the bolts to complete the fixed installation of the upper mold 207. When replacing the lower mold 201, the operator rotates the rotating shaft 305 on one side of the base 1. The rotating shaft 305 drives the gear 303 to rotate inside the mounting box 301. The gear 303 meshes with the rack 304, causing the rack 304 to slide away from the lower mold 201 against the elastic force of the spring 307. The rack 304 drives the mounting rod 308 and the limiting block 309 to move synchronously. When the limiting block 309 is completely disengaged from the side wall of the old lower mold 201, the rotating shaft 305 is stopped. At this time, the old lower mold 201 can be pulled out to the part removal station along the sliding structure of the inner wall of the base 1. Then, the new lower mold 201 is pushed into the processing station along the sliding structure. After releasing the rotating shaft 305, the spring 307 pulls the rack 304 back to its original position through the connecting block 306. The rack 304 drives the mounting rod 308 and the limiting block 309 to re-fit against the side wall of the lower mold 201, completing the limiting and fixing of the lower mold 201. After the mold is changed, the operator lays the cut carbon fiber prepreg inside the cavity of the lower mold 201 according to the preset layup method, ensuring that the prepreg is laid flat and without wrinkles. Then, the external control system of the device is activated, the hydraulic rod 204 is energized and extends downward, pushing the upper mold 207 slowly downward through the connecting rod 205 until the upper mold 207 and the lower mold 201 are completely closed. At this time, the hydraulic rod 204 maintains a stable pressure according to the preset process parameters. At the same time, the heating plate 206 is energized and the heat generated is transferred to the upper mold 207 through the inner wall of the connecting rod 205, and further transferred to the lower mold 201 and the carbon fiber prepreg inside, so that the prepreg gradually solidifies and forms under the set temperature and pressure. After the carbon fiber frame has cured and formed, the control system first shuts off the heating plate 206. After the mold temperature drops to a safe range, the control hydraulic rod 204 retracts upward, driving the upper mold 207 to slowly move upward and reset until the upper mold 207 is completely separated from the lower mold 201. The operator then rotates the rotating shaft 305 to release the limit of the lower mold 201 and slides the lower mold 201 along the inner wall of the base 1 to the part removal station. Then, a special tool is used to remove the formed carbon fiber frame from the cavity of the lower mold 201. The appearance and dimensions of the frame are checked to see if they meet the requirements. If they do, the processing is completed. If there are minor deviations, they are simply corrected before removal. Finally, the lower mold 201 is pushed back to the processing station and the limit is reset.
