[0002] Carbon fiber molding equipment refers to a machine that puts pre-impregnated carbon fiber cloth into a molding mold, and after closing the mold, adjusts pressure, temperature, and time to make the desired carbon fiber product. Carbon fiber is a new type of fiber material with a carbon content of more than 95%, high strength, and high modulus. It is a microcrystalline graphite material obtained by carbonization and graphitization by stacking organic fibers such as flaky graphite microcrystals along the axial direction of the fiber. Carbon fiber is "soft on the outside and hard on the inside", lighter than metal aluminum, but stronger than steel, and has the characteristics of corrosion resistance and high modulus.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0020] See also Figure 1-Figure 8A carbon fiber composite material continuous thermoplastic molding profile equipment, comprising a body 1, the body 1 is connected to a machine platform 3 through four guide rods 8, a hydraulic press 2 is installed on the body 1, an upper die 4 is connected to the output shaft of the hydraulic press 2, a lower die 7 is arranged on the machine platform 3, a self-laying mechanism 5 and a self-discharging mechanism 6 are arranged on the machine platform 3, a heating module is arranged inside the machine platform 3, the heating module realizes molding heating for the lower die 7 and the upper die 4; the self-laying mechanism 5 comprises a receiving bracket 501 and a placing bracket 503, the receiving bracket 501 and the placing bracket 50 3 are respectively rolled up with upper and lower paving materials 502 and 504 through the rotating shaft, and the traditional manual paving is converted into automatic multi-layer paving of winding type, so as to maximize the production efficiency. It is necessary to cut and unwind by another device, so that multiple processes are directly combined in one process to improve efficiency. The operator can control which paving material is on the upper and which paving material is on the lower according to actual needs. The lower pressing die 7 is provided with an annular groove 701, and the upper pressing die 4 is provided with an annular cutter 401 matched with the annular groove 701. The continued downward pressure of the hydraulic press 2 will drive the upper pressing die 4 at the bottom to close the mold with the lower pressing die 7 below, and the annular cutter 401 will press down and cut the paving material to avoid cutting interference with the lower pressing die 7, so the annular groove 701 is set to fully match the annular cutter 401, and then the cut paving material is molded with the combination of the upper pressing die 4 and the lower pressing die 7.

[0021] In this embodiment, guide frames 505 are respectively installed on the left and right upper surfaces of the machine 3, and two guide rollers 506 are rotatably connected inside the guide frames 505. The upper layer of the paving material 502 and the lower layer of the paving material 504 respectively pass through the two guide rollers 506. By setting the horizontal guide rollers 506 on both sides, the paving material will be controlled to be in a horizontal state, thereby improving the later compression molding effect.

[0022] Furthermore, a cross 510 is connected to the output shaft of the hydraulic press 2, and a conveying tooth plate 507 is connected to the cross 510 through a connecting piece. Two gears are meshed on one side of the conveying tooth plate 507, and the two gears are respectively connected to the two rotating shafts in the receiving bracket 501. The cross 510 is slidably connected to the guide rod 8, and ratchet wheels 514 are fixedly connected to the two rotating shafts in the receiving bracket 501. A ratchet 515 is rotatably connected to one side of the receiving bracket 501, and the ratchet 515 is clamped on the ratchet wheel 514. Two connecting pieces are provided, and the connecting piece includes a sliding sleeve, and a contraction rod 508 is slidably connected inside the sliding sleeve, and one end of the contraction rod 508 is fixedly connected to the conveying tooth plate 507, and the other end of the contraction rod 508 is connected to a yield spring 509, and one end of the yield spring 509 is connected to the inside of the sliding sleeve. After the hydraulic press 2 moves up, in order to avoid causing the rotating shaft on the receiving bracket 501 to reverse, a ratchet 514 and a ratchet 515 are set. When the cross 510 is lifted up, the conveying tooth plate 507 will also move up synchronously. At this time, although the conveying tooth plate 507 is engaged with the gear, it will not flip due to the ratchet 514, and the conveying tooth plate 507 will squeeze the give way spring 509 through the two retraction rods 508 to give way, and move up again and slide to the top, so at this time, one-way movement winding is realized, and finally one-way winding and spreading are realized, combining winding and spreading.

[0023] Furthermore, the self-discharging mechanism 6 includes a rotating sleeve 511, which is rotatably connected to the guide rod 8, and the bottom of the rotating sleeve 511 is fixedly connected to a power gear 603, on which a sliding tooth plate 602 is meshed, and one end of the sliding tooth plate 602 is rotatably connected to a sliding shaft 601, on which a fixed gear 617 is fixedly connected, and on which a fixed gear 617 is meshed, a fixed tooth plate 605 is fixed, and the fixed tooth plate 605 is fixed on the machine table 3, and the lower die 7 is fixed on the sliding shaft 601. When the cross 510 rises, the sliding pin 517 is also controlled to slide on the spiral groove 512. By utilizing the spiral structure of the spiral groove 512, when the sliding pin 517 slides, it will drive the rotating sleeve 511 to rotate, and then drive the power gear 603 to rotate. The power gear 603 is in a meshing state with the sliding tooth plate 602, so the sliding tooth plate 602 will push the lower die 7 connected to the sliding shaft 601 to achieve lateral movement. During the movement, the fixed gear 617 will be meshed with the fixed tooth plate 605 to control the direct flipping of the lower die 7, and then the profile inside the lower die 7 will be automatically flipped and discharged.

[0024] In addition, a discharging rack 607 is connected to one side of the machine 3, and two suction cups 606 are installed on the discharging rack 607. A push plate 608 is rotatably connected to the sliding shaft 601 below the lower die 7. The push plate 608 is slidably connected to the machine 3. A limit plate 604 is fixedly installed on the machine 3, and the limit plate 604 is slidably connected to the sliding tooth plate 602 through a T-slot. The two suction cups 606 are used to absorb the profile, and when the material of the previous process is on the suction cup 606, the push plate 608 will follow the movement of the sliding shaft 601 to squeeze the profile out of the suction cup 606, so that it falls onto the discharging rack 607, so the overall process of automatic discharging and automatic material return is realized.

[0025] In addition, a slide pin 517 is fixedly connected to the cross 510, a spiral groove 512 is provided on the rotating sleeve 511, and an upper straight groove 516 and a lower straight groove 513 are also provided on the rotating sleeve 511. The upper straight groove 516 and the lower straight groove 513 are respectively connected to the two ends of the spiral groove 512, and the slide pin 517 is slidably connected inside the spiral groove 512. The upper straight groove 516 and the lower straight groove 513 are provided on the rotating sleeve 511, because it is also necessary to ensure that the mold cannot move during the mold closing process, and it must be at the molding station, so when the slide pin 517 enters the lower straight groove 513 from the spiral groove 512, the rotating sleeve 511 will not move, and the indirect lower pressing mold 7 will not move, and finally the entire mold will be in a relatively stable state to achieve thermoplastic molding.

[0026] It is worth noting that the self-discharging mechanism 6 also includes a connecting frame 609, the two ends of the connecting frame 609 are connected to the guide frame 505, a plurality of slide tubes 610 are slidably connected to the connecting frame 609, a brush 612 is connected to the bottom of the slide tube 610, an extrusion spring 611 is sleeved on the slide tube 610, one end of the extrusion spring 611 is connected to the connecting frame 609, the other end of the extrusion spring 611 is connected to the slide tube 610, and a release agent is arranged on the brush 612. A cavity is arranged inside the guide frame 505, a release agent is arranged inside the cavity, the cavity is connected to a plurality of slide tubes 610 through pipelines, an upper pressing plate 614 is slidably connected in the cavity, a rear push plate 615 is slidably connected to the bottom of the upper pressing plate 614 through an inclined surface, an extrusion member 616 is connected to the rear push plate 615 through a shaft, and a sealing cap 613 is threadedly connected to the guide frame 505. The operator can open the sealing cap 613 from time to time and inject a certain amount of release agent. Then, as the lower die 7 is reset, the protrusions are set on the sliding tooth plate 602, which will contact and press against the extrusion piece 616, and then drive the rear push plate 615 to move horizontally, and use the sliding of the inclined surface to drive the upper pressing plate 614 to lift, and squeeze the internal release agent upward through the pipeline into the interior of the slide tube 610, and then flow to the brush 612, so that every time the lower die 7 slides out or slides in, the brush 612 will apply a layer of release agent to the upper surface of the profile, and when sliding in, it will apply it to the inside of the cavity, so as to realize automatic application of release agent, which is convenient for later demoulding and discharging. The brush 612 can also be replaced with a nozzle, and the application can also be realized by spraying, and the purpose of multiple extrusion springs 611 is to realize the elastic movement of the brush 612 up and down, avoiding the movement interference caused by the lower die 7 during the lateral movement. Embodiment 2

[0027] A carbon fiber composite material continuous thermoplastic molding profile process, comprising the following steps: Step 1: Hanging the materials, placing the complete rolled composite material and carbon fiber material rolls on the two rotating shafts on the placing bracket 503 respectively, then pulling the end faces, passing through the two guide rollers 506, and then clamping them on the two rotating shafts on the receiving bracket 501 to achieve transmission; Step 2: drive and control the downward movement of the hydraulic press 2, which will drive the cross 510 to move downward synchronously, and then drive the conveying gear plate 507 to move downward. After the meshing between the gears, the two shafts will be controlled to rotate, and the paving materials on the upper and lower sides will be rolled up, and the complete paving materials will be transmitted to the bottom of the upper die 4; Step 3: die cutting. The hydraulic press 2 continues to press down, which will control the upper die 4 and the lower die 7 to close the mold. In the closing mold, the annular cutter 401 will press and cut the two layers of the paving material. The annular cutter 401 and the annular cutting groove 701 cooperate to cut the paving material. The cut paving material will be formed following the closing mold process. Step 4: Pressure holding and heating for shaping. The heating module will quickly heat up the two molds in the mold, and the paving material in the mold will be molded and thermoplasticized. The pressure holding time and heating temperature are selected according to the thickness of the paving material. Step 5: Reset the discharge. After forming, the upward movement of the hydraulic press 2 will drive the lifting of the cross 510, and the two sliding pins 517 on the cross 510 will slide in the spiral groove 512, thereby driving the rotation of the rotating sleeve 511, and the rotation of the rotating sleeve 511 will drive the rotation of the power gear 603. Similarly, the meshing transmission of the gears is used to drive the lateral movement of the sliding tooth plate 602, thereby driving the lower die 7 to be automatically pushed out, and controlling the lower die 7 to achieve flipping, and dumping the formed profile to the position of the discharge rack 607.

[0028] Working principle: the operator sets the complete rolled composite material and carbon fiber material coils on the two rotating shafts on the bracket 503, and then pulls the end face, passes through the two guide rollers 506, and then clamps it on the two rotating shafts on the receiving bracket 501 to realize transmission. After that, the operator controls the downward movement of the hydraulic press 2, which will drive the synchronous downward movement of the cross 510, and then drive the downward movement of the conveying tooth plate 507. After the meshing between the gears, the two rotating shafts will be controlled to rotate, and the paving materials on the upper and lower sides will be rolled up, and the complete paving materials will be transmitted from the bracket 503 to the bottom of the upper die 4. There is a section without teeth on the upper part of the conveying tooth plate 507, and this section is actually the action length of the mold during molding. Because it is necessary to ensure that the paving materials cannot move at this time when the mold is closed, so after the conveying tooth plate 507 moves to the position without teeth, the paving materials will be in a relatively static state. After that, the hydraulic press 2 continues to press down, which will drive the upper die 4 at the bottom to close the mold with the lower die 7 below, and the annular cutter 401 will press down and cut the paving material to avoid cutting interference with the lower die 7, so the annular cutter 701 is set to fully match the annular cutter 401, and then the cut paving material is molded with the merging of the upper die 4 and the lower die 7. At this time, the heating module heats the mold after closing the mold at a high temperature to make the paving material fully fused together for easy molding and curing. The operator can control the holding time and heating temperature after closing the mold according to the thickness of the paving material and the size of the product.After the forming is completed, after the hydraulic press 2 moves up, in order to avoid causing the rotating shaft on the receiving bracket 501 to reverse, a ratchet 514 and a ratchet card 515 are set. When the cross 510 is lifted up, the conveying tooth plate 507 will also move up synchronously. At this time, although the conveying tooth plate 507 is engaged with the gear, it will not flip due to the ratchet 514, and the conveying tooth plate 507 will squeeze the give way spring 509 through the two retracting rods 508 to give way, and then move up and slide to the top again, so at this time, a one-way movement is realized, and when the cross 510 rises, it will also control the sliding pin 517 to slide on the spiral groove 512; using the spiral structure of the spiral groove 512, when the sliding pin 517 slides, it will drive the rotating sleeve 511 to rotate, and then drive the rotation of the power gear 603, and the power gear 603 and The sliding tooth plate 602 is in meshing state, so the sliding tooth plate 602 will push the lower die 7 connected to the sliding shaft 601 to achieve lateral movement. During the movement, the fixed gear 617 will be meshed with the fixed tooth plate 605 to control the direct flipping of the lower die 7. Because the fixed gear 617, the lower die 7 and the sliding shaft 601 are in a relatively fixed connection, the rotation of the fixed gear 617 will directly drive the flipping of the lower die 7, and then flip the profile inside the lower die 7. After flipping, the two suction cups 606 are used to adsorb the profile. When the material of the previous process is on the suction cup 606, the push plate 608 will follow the movement of the sliding shaft 601 to squeeze the profile out of the suction cup 606, so that it falls onto the discharge rack 607, so the overall process of automatic discharge and automatic return is realized. Then, as the hydraulic press 2 continues to press down, the sliding pin 517 will continue to slide on the spiral groove 512, controlling the reverse rotation of the rotating sleeve 511, thereby driving the multiple structures in the discharge process to reset and reset them to the molding station. The upper straight groove 516 and the lower straight groove 513 are set on the rotating sleeve 511, because it is also necessary to ensure that the mold cannot move during the mold closing process and must be at the molding station. Therefore, when the sliding pin 517 enters the lower straight groove 513 from the spiral groove 512, the rotating sleeve 511 will not move, and the indirect lower pressing mold 7 will not move. Finally, the entire mold will be in a relatively stable state to achieve thermoplastic molding.
