Description

Technical Field

[0001] This utility model belongs to the technical field of hot pressing forming equipment, specifically relating to a hot pressing forming equipment for carbon fiber sheets. Background Technology

[0002] Carbon fiber sheets, as a high-performance composite material, are high-performance sheets made by composite processes using carbon fiber as the reinforcing material and resin as the matrix. They possess excellent properties such as lightweight and high strength, corrosion resistance, fatigue resistance, and high design freedom, and are widely used in aerospace, automotive manufacturing, and sporting goods industries. Their manufacturing process typically involves hot pressing, which uses heat and pressure to solidify and shape the carbon fiber raw material.

[0003] Traditional hot pressing molding equipment has many limitations. First, most devices rely on manual operation for unloading, requiring workers to manually remove the molded carbon fiber sheets. This is not only inefficient but also prone to causing surface scratches or structural damage due to improper operation. Second, existing automated unloading devices often use multiple actuators to control pressing and lifting in stages, resulting in a complex overall structure, high cost, and difficult maintenance. Therefore, there is an urgent need for a hot pressing molding device for carbon fiber sheets.

[0004] A patent with publication number CN222004137U discloses a carbon fiber sheet forming device, which includes a forming groove, a hydraulic cylinder, a mounting plate, an upper forming plate, an electric push rod, a lower forming plate, a motor, a pusher frame, and a loading frame. In operation, carbon fiber raw material is first added to the forming groove. The extension shaft of the hydraulic cylinder pushes the mounting plate and the upper forming plate downwards to compress the raw material. After processing, the extension shaft of the electric push rod pushes the lower forming plate upwards to lift the carbon fiber sheet. Once the carbon fiber sheet has risen to a certain position, the output shaft of the motor drives the pusher frame to move, pushing the carbon fiber sheet into the loading frame.

[0005] However, after the carbon fiber sheet is processed and shaped, the above solution not only requires a hydraulic cylinder to drive the upper forming plate back to its original position, but also necessitates the activation of an electric push rod to lift the lower forming plate. Furthermore, after lifting, a separate motor is required to drive the pusher frame to perform the unloading action. This process relies on multiple independent drive sources, significantly increasing the production and maintenance costs of the equipment, and leading to a complex control system structure and difficulty in coordinated control, thus hindering the promotion and application of this technology in actual production. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides a hot pressing forming device for carbon fiber sheets.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

During this process, a lifting mechanism pushes the lower molding plate upwards automatically with the assistance of a first transmission component, thus lifting the carbon fiber sheet. Furthermore, once the lower molding plate is flush with the mold opening, the continued rise of the upper pressure plate further drives a second transmission component, causing the pushing mechanism to automatically move towards the mold box, thereby pushing the carbon fiber sheet on top of the lower molding plate for automatic unloading. The entire demolding and unloading process is completed seamlessly without any additional driving intervention, thereby reducing production and maintenance costs while lowering the complexity of the control system construction, making it highly valuable for market promotion.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a carbon fiber sheet hot pressing molding device includes a box body 1, an installation plate 2 is integrally fixedly installed in the middle of the box body 1, and an installation mold box 5 is fixedly embedded in the top of the installation plate 2; a lower forming plate 20 is both limited and slidably installed in the mold box 5 along the vertical direction, and a lifting mechanism is provided to act on the lower forming plate 20, and a carbon fiber sheet 16 is placed on the top of the lower forming plate 20.

[0027] An upper pressure plate 15 is vertically limited and slidably installed directly above the lower forming plate 20. A lifting mechanism acting on the upper pressure plate 15 is provided on the housing 1, and a first transmission component is provided between the lifting mechanism and the lifting mechanism.

[0028] Furthermore, a T-shaped forming groove is provided inside the mold box 5, and the lower forming plate 20 and the lifting mechanism are both limited and slidably fitted with the forming groove.

[0029] Furthermore, the upper pressure plate 15 has a built-in heating component, and the mold box 5 has a built-in cooling component. The heating component is used to realize hot pressing and molding, and the cooling component is used to cool down the molded carbon fiber plate 16 to facilitate demolding. Both are conventional prior art, and this application will not describe them in detail.

[0030] The lifting mechanism includes a servo electric cylinder 13. The servo electric cylinder 13 is fixedly installed on the top of the housing 1. The telescopic shaft of the servo electric cylinder 13 is fixedly provided with a support plate 12. The support plate 12 is fixedly connected to the upper pressure plate 15.

[0031] The lifting mechanism includes a slide rod 18, which is slidably and vertically inserted into the forming groove. The top of the slide rod 18 is fixedly connected to the lower forming plate 20, and the bottom of the slide rod 18 is fixedly connected to a connecting plate 9.

[0032] The first transmission component includes a movable rod 14. Two movable rods 14 are fixedly installed on the outer surface of the support plate 12. The two movable rods 14 are symmetrically arranged on both sides of the support plate 12. The bottom of each movable rod 14 not only limits the sliding through the mounting plate 2 and the connecting plate 9, but also has a fixed mounting block 7.

[0033] A first spring 17 is provided between the mounting block 7 and the connecting plate 9. The first spring 17 is sleeved on the outer surface of the movable rod 14. One end of the first spring 17 is fixedly connected to the connecting plate 9, and the other end is fixedly connected to the mounting block 7.

[0034] As the upper pressure plate 15 descends via the output shaft of the servo electric cylinder 13, the lower forming plate 20 remains abutted against the mold box 5 without sliding. The upper pressure plate 15 gradually moves closer to the carbon fiber plate 16, and the first spring 17 is stretched, thus performing the hot pressing forming operation. Conversely, as the upper pressure plate 15 rises via the output shaft of the servo electric cylinder 13, the support plate 12 pushes the connecting plate 9 upwards via the movable rod 14 and the first spring 17, thereby using the sliding rod 18 to push the lower forming plate 20 and the carbon fiber plate 16 upwards, thus achieving the lifting operation.

[0035] In addition, a pushing mechanism is provided on the mounting plate 2 along the horizontal direction for limiting sliding. The pushing mechanism moves closer to or away from the mold box 5, and the mounting block 7 acts on the pushing mechanism through the second transmission component.

[0036] The material pushing mechanism includes a bending rod 3, a groove 22 is opened on the mounting plate 2, the bending rod 3 is slidably set in the groove 22, and a push rod 4 is integrally fixed on the top of the bending rod 3.

[0037] The second transmission component includes a wedge block 6, which is integrally fixed to the bottom of the bent rod 3. The bottom of the wedge block 6 is sloped. A lever 8 is fixed between the two mounting blocks 7, and the lever 8 is in contact with the sloped bottom of the wedge block 6 for transmission.

[0038] A guide rod 19 is fixedly installed on the inner wall of the box 1 in the horizontal direction. The end of the guide rod 19 that is not connected to the box 1 slides through the wedge block 6 and is fixedly installed as a limit block. A second spring 21 is sleeved on the outer surface of the guide rod 19. One end of the second spring 21 is fixedly connected to the wedge block 6 and the other end is fixedly connected to the box 1.

[0039] Furthermore, an inclined block 11 is fixedly installed on the top of the mounting plate 2, and a collection box 10 is fixedly installed on the outer surface of the box body 1; the high end of the inclined block 11 corresponds to the mold box 5, and the low end of the inclined block 11 corresponds to the collection box 10.

[0040] Working principle: Initial state as follows Figure 1 as well as Figure 2 As shown, at this time, both the first spring 17 and the second spring 21 are in their natural state, and the bottom of the lower forming plate 20 is in contact with the mold box 5.

[0041] The carbon fiber plate 16 is placed on the lower forming plate 20 inside the mold box 5.

[0042] Subsequently, the servo electric cylinder 13 is activated, and the support plate 12 and the upper pressure plate 15 are pushed downward through the telescopic shaft of the servo electric cylinder 13. The lower forming plate 20 remains stationary due to the limitation of the mold box 5, while the upper pressure plate 15 continues to press down and hot-press the carbon fiber plate 16. During this process, the movable rod 14 fixed to the support plate 12 moves downward relative to the connecting plate 9, causing the first spring 17 to be stretched.

[0043] After the carbon fiber plate 16 is processed and formed, the support plate 12 and the upper pressure plate 15 are raised by the telescopic shaft of the servo electric cylinder 13, so that the stretched first spring 17 gradually returns to its initial state. After the first spring 17 returns to its initial state, as the support plate 12 continues to rise, the mounting block 7 begins to push the connecting plate 9 up through the first spring 17.

[0044] The rising of the connecting plate 9 will cause the lower molding plate 20 and the already formed carbon fiber plate 16 to rise together via the slide rod 18 until the top surface of the lower molding plate 20 is flush with the top of the mold box 5, completing the demolding. At this time, the connecting plate 9 is just abutting against the bottom of the mounting plate 2.

[0045] Subsequently, the servo electric cylinder 13 continues to drive the support plate 12 to rise. As the connecting plate 9 abuts against the mounting plate 2, the movable rod 14 is forced to move upward relative to the connecting plate 9, causing the first spring 17 to be compressed. The rise of the movable rod 14 drives the lever 8 to rise synchronously, causing the lever 8 to contact the inclined surface of the wedge block 6, thereby converting the vertical motion into a horizontal thrust, which in turn overcomes the elastic force of the second spring 21 and pushes the bending rod 3 and the push rod 4 to move along the slide 22 towards the mold box 5.

[0046] As push rod 4 moves, it pushes carbon fiber plate 16 from the top of lower molding plate 20 onto inclined block 11, causing the plate to slide along the inclined surface of inclined block 11 into collection box 10, thus completing automatic unloading. The entire demolding and unloading process is completed in one go, without any additional drive intervention, thereby reducing production and maintenance costs while reducing the construction difficulty of the control system, making it highly valuable for market promotion.

[0047] When the servo electric cylinder 13 drives the upper pressure plate 15 downward again, each mechanism automatically resets, thus preparing for the next work cycle.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
