Description

Technical Field

[0001] The present invention relates to the technical field of forming dies, in particular to a carbon fiber composite material forming die with a heat-insulating function. Background Art

[0002] In the field of carbon fiber composite molding and processing, the thermal insulation performance of the mold plays an important role in product quality and production efficiency. However, the current traditional carbon fiber composite molding molds have many problems in thermal insulation. On the one hand, traditional molds often lack effective heat collection and conduction mechanisms. During the injection molding process, a large amount of heat will dissipate with the injection molding operation. This dissipated heat cannot be reasonably utilized, resulting in energy waste. At the same time, due to the uneven heat distribution inside the mold, the temperature difference between different parts during the molding process is large, which easily causes quality defects in the carbon fiber composite material during molding, such as local deformation, incomplete curing, etc., which will affect the quality and performance of the product. On the other hand, the thermal insulation effect of traditional molds is poor, and heat dissipation is fast. After the molding operation is completed, the temperature inside the mold is difficult to maintain at a stable level, and the heat is quickly dissipated to the outside, which affects the subsequent processing operations. In order to maintain the temperature of the mold, heat needs to be continuously added, which not only increases energy consumption, but also prolongs the production cycle. Frequent heating and cooling of the mold will also have a negative impact on the service life of the mold. Summary of the Invention

When the adjusting device 55 stops blocking the ventilation groove 57, heat will enter the interior of the movable box 53 through the ventilation groove 57. Since the movable box 53 is connected to the hollow ring 52, heat enters the square tube 561 through the hollow ring 52;

[0038] The adjusting device 55 includes a servo motor 551, and the output end of the servo motor 551 is fixedly connected to an adjusting screw 552, the outer wall of the adjusting screw 552 is threadedly connected to an L-shaped plate 553, and the inner wall of the L-shaped plate 553 is slidably connected to a fixing rod 554, and the outer wall of the fixing rod 554 is sleeved with a compression spring 555. The adjusting device 55 drives the adjusting screw 552 to rotate through the servo motor 551. Since the adjusting screw 552 is threadedly connected to the L-shaped plate 553 and the L-shaped plate 553 slides on the fixing rod 554, the compression spring 555 provides a certain buffering force, so that the L-shaped plate 553 is always subjected to an upward thrust during the downward movement, thereby reducing the virtual position of the L-shaped plate 553, so that when the airflow flows, the vibration impact on the L-shaped plate 553 is reduced. When the servo motor 551 is started, the adjusting screw 552 drives the L-shaped plate 553 to move up and down, and the L-shaped plate 553 blocks the ventilation groove 57 when it is above.

[0039] The outer wall of the bottom of the connecting plate 3 is fixedly connected to the outer wall of the top of the servo motor 551, the outer wall of the fixed frame 51 is fixedly connected to the inner wall of the upper mold base 2, the outer wall of the movable box 53 is fixedly connected to the outer wall of the fixed frame 51, the outer wall of the bottom of the movable box 53 is fixedly connected to the outer wall of the bottom of the fixed rod 554, the side wall inside the movable box 53 is slidingly connected to the outer wall of the L-shaped plate 553, one end of the compression spring 555 is fixedly connected to the outer wall of the bottom of the movable box 53, and the other end of the compression spring 555 is fixedly connected to the outer wall of the bottom of the L-shaped plate 553.

Thereafter, the ventilation groove 57 is opened by adjusting the position of the L-shaped plate 553. After the air circulates, the hot air and the cold air come into contact with each other, thereby enhancing convection, so that the heat circulates in the connecting device 4 and the movable box 53, thereby accelerating the heating inside the mold.

[0040] The connecting device 4 includes a connecting box 41, the outer wall of the bottom of the connecting box 41 is fixedly connected to a heat conducting pipe 42, the outer wall of the top of the connecting box 41 is fixedly connected to a fixed box 43, the inner wall of the fixed box 43 is fixedly connected to a wrapping ring 44, the outer wall of the fixed box 43 is provided with a connecting groove 45, the outer wall of the bottom of the fixed box 43 is fixedly connected to a fixing plate 46, the outer wall of the fixing plate 46 is fixedly connected to a grid plate 47, the outer wall of the connecting box 41 is fixedly connected to the inner wall of the upper mold base 2, the heat conducting pipe 42 at the bottom of the connecting box 41 can introduce part of the heat dissipated during the injection molding process into the connecting box 41, the fixed box 43 at the top of the connecting box 41 exchanges heat with the insulation device 5 through the connecting groove 45, the wrapping ring 44 is fixed to the inner wall of the fixed box 43, which protects and positions the internal components, the fixing plate 46 and the grid plate 47 are fixed to the bottom of the fixed box 43, the grid plate 47 can increase the area and efficiency of heat transfer, so that the heat is more evenly distributed in the connecting device 4, and the design of the connecting device 4 enables heat to be effectively conducted inside the mold.

[0041] The positioning device 54 includes a protective frame 541. The side wall inside the protective frame 541 is provided with a reflective coating 542. The inside of the protective frame 541 is provided with a gas storage tube 543. The outer wall of the protective frame 541 is fixedly connected to the inner wall of the wrapping ring 44. The protective frame 541 of the positioning device 54 is provided with a reflective coating 542 and a gas storage tube 543. The reflective coating 542 can reflect heat and reduce heat loss to the outside. The gas storage tube 543 is used to store heat. The protective frame 541 is fixedly connected to the inner wall of the wrapping ring 44, which further enhances the utilization of heat.

[0042] The switch device 56 includes a square tube 561, a connecting hole 562 is opened in the wall of the square tube 561, a sliding block 563 is slidably connected to the inner wall of the square tube 561, and a blocking device 564 is fixedly connected to the outer wall of the sliding block 563. The inner wall of the sliding block 563 is fixedly connected to the limiting rod 565, and the inner wall of the square tube 561 is fixedly connected to the fixing sleeve 566. The inner wall of the fixing sleeve 566 is slidably connected to the outer wall of the limiting rod 565. The end of the limiting rod 565 away from the sliding block 563 is fixedly connected to a tension spring 567. The square tube 561 is connected to the hollow ring 52, the sliding block 563 slides in the square tube 561, the limiting rod 565 slides in the fixing sleeve 566, and the tension spring 567 provides a reset force. When convection needs to be strengthened, the linkage device 58 opens the openings at both ends of the gas storage tube 543, namely the connection hole 562. The fixed shaft 581 of the linkage device 58 is fixed to the inner wall of the L-shaped plate 553. The notched plate 582, sliding shaft 583, rotating ring 584, rotating rod 585 and pushing ring 586 cooperate with each other. When the adjustment device 55 moves downward, the notched plate 582 is driven to move by the fixed shaft 581. Since the rotation position of the rotating rod 585 is fixed, when the sliding shaft 583 slides in the notched plate 582, it will drive the rotating ring 584 to rotate, and then drive the rotating rod 585 to rotate. The synchronously rotating pushing ring 586 will generate a pushing force on the limit rod 565 of the switch device 56, thereby pushing the blocking device 564 away from the connection hole 562, thereby opening the passage of the gas storage tube 543.

[0043] The blocking device 564 includes a fixed block 5641, the inner wall of the fixed block 5641 is fixedly connected to a damping rod 5642, the outer wall of the damping rod 5642 is sleeved with a return spring 5643, the outer wall of the damping rod 5642 is fixedly connected to a movable column 5644, one end of the return spring 5643 is fixedly connected to the outer wall of the movable column 5644, the other end of the return spring 5643 is fixedly connected to the inner wall of the fixed block 5641, the outer wall of the movable column 5644 is slidably connected to the inner wall of the fixed block 5641, the outer wall of the bottom of the fixed block 5641 is fixedly connected to the outer wall of the top of the sliding block 563, the outer wall of the square tube 561 is fixedly connected to the outer wall of the hollow ring 52, and the square tube 561 is connected to the hollow ring 52, and the sliding block 563 moves in the square tube 561 to open the connection Hole 562 allows heat to flow smoothly. The fixed block 5641 of the blocking device 564 is fixed on the sliding block 563. The damping rod 5642, the return spring 5643 and the movable column 5644 cooperate with each other. When the movable column 5644 is subjected to external force, it retracts into the fixed block 5641 and slides along the axial direction of the damping rod 5642, compressing the return spring 5643 to realize the opening and closing control of the circulation channel. When heat enters the movable box 53, the switch device 56 opens the circulation channel and stores the heat in the gas storage pipe 543. It is closed after the heat stabilizes. After the injection molding is completed, the switch device 56 and the L-shaped plate 553 of the movable adjustment device 55 are opened again to release the gas in the gas storage pipe 543, so that the internal convection is again carried out, thereby slowing down the rate of heat loss inside the mold.

[0044] The linkage device 58 includes a fixed shaft 581, the outer wall of the fixed shaft 581 is fixedly connected to the notch plate 582, the inner wall of the notch plate 582 is slidably connected to the sliding shaft 583, the outer wall of the sliding shaft 583 is rotatably connected to the rotating ring 584, the outer wall of the rotating ring 584 is fixedly connected to the rotating ring 584, the side wall inside the rotating ring 584 is fixedly connected to the rotating rod 585, the outer wall of the rotating rod 585 is fixedly connected to the pushing ring 586, the outer wall of the rotating rod 585 is rotatably connected to the inner wall of the movable box 53, the outer wall of the rotating rod 585 is rotatably connected to the inner wall of the square tube 561, and the outer wall of the fixed shaft 581 is fixedly connected to the outer wall of the L-shaped plate 553.

[0045] Example 2: Please refer to Figure 1 - Figure 11The present invention provides a technical solution: on the basis of embodiment 1, the port protection device 59 includes a positioning sleeve 591, the inner side wall of the positioning sleeve 591 is symmetrically fixedly connected with an elastic sheet 592, the outer wall of the elastic sheet 592 is fixedly connected with a connecting sleeve 593, the outer side wall of the connecting sleeve 593 is fixedly connected with a corrugated sleeve 594, the outer wall of the connecting sleeve 593 is fixedly connected to the outer wall of the gas storage pipe 543, the outer wall of the positioning sleeve 591 is fixedly connected to the inner side wall of the protection frame 541, the positioning sleeve 591 of the port protection device 59 is fixed to the inner side wall of the protection frame 541, the elastic sheet 592 and the connecting sleeve 593 and the corrugated sleeve 594 cooperate with each other, so that the port position of the gas storage pipe 543 has pressure resistance, and the elastic sheet 592 and the corrugated sleeve 594 offset the inertia brought by the movement of the upper mold base 2, thereby playing a protective role for the port of the gas storage pipe 543.

[0046] When in use, the carbon fiber composite material forming mold with heat preservation function, the lower mold base 1 and the upper mold base 2 form the basic frame of the mold, the connecting plate 3 on the top of the upper mold base 2 is used to connect external equipment and provide power support for operations such as opening and closing of the mold, and the wrapping frame 6 is fixed to the inner wall of the upper mold base 2 to accommodate the carbon fiber composite material and ensure the stable position of the material during the molding process.

[0047] The connecting device 4 is mainly responsible for the conduction and circulation of heat. The heat pipe 42 at the bottom of the connecting box 41 can introduce part of the heat dissipated during the injection molding process into the connecting box 41. The fixed box 43 on the top of the connecting box 41 exchanges heat with the heat preservation device 5 through the connecting groove 45. The wrapping ring 44 is fixed to the inner wall of the fixed box 43 to protect and position the internal components. The fixing plate 46 and the grid plate 47 are fixed to the bottom of the fixed box 43. The grid plate 47 can increase the area and efficiency of heat transfer, so that the heat is more evenly distributed in the connecting device 4. The design of the connecting device 4 enables heat to be effectively conducted inside the mold, which helps to improve the molding quality and reduce product defects caused by uneven temperature.

[0048] The heat preservation device 5 is one of the main parts of the mold with heat preservation function, which is used to maintain the temperature inside the mold stable. The fixed frame 51 is fixed to the inner wall of the upper mold base 2 to provide a support structure for the heat preservation device 5. The hollow ring 52 is connected to the movable box 53, which plays a role in heat transmission and storage. The ventilation groove 57 of the movable box 53 is connected to the communication groove 45, and an adjustment device 55 controls whether it is connected. When the adjustment device 55 stops blocking the ventilation groove 57, heat will enter the interior of the movable box 53 through the ventilation groove 57. Since the movable box 53 and the hollow ring 52 are connected, the heat enters the square tube 561 through the hollow ring 52;

[0049] The adjusting device 55 controls whether the vent slot 57 is ventilated, wherein the adjusting device 55 drives the adjusting screw 552 to rotate through the servo motor 551. Since the adjusting screw 552 is threadedly connected to the L-shaped plate 553, and the L-shaped plate 553 slides on the fixing rod 554, the compression spring 555 provides a certain buffer force, so that the L-shaped plate 553 is always subjected to an upward thrust during the downward movement, thereby reducing the virtual position of the L-shaped plate 553, so that when the airflow flows, the vibration effect on the L-shaped plate 553 is reduced. When the servo motor 551 is started, the adjusting screw 552 drives the L-shaped plate 553 to move up and down. When the L-shaped plate 553 is at the top, it blocks the ventilation slot 57. Since the connecting device 4 is close to the injection position, the interior of the connecting device 4 is locally heated at this time, and the heat is concentrated in the local area, thereby improving the heating efficiency. Then, by adjusting the position of the L-shaped plate 553 to open the ventilation slot 57, after the air circulates, the hot air and the cold air come into contact with each other, thereby enhancing convection, causing the heat to circulate in the connecting device 4 and the movable box 53, thereby accelerating the heating inside the mold. This adjustable heating method can control the heating speed and heat distribution according to the different stages of composite material molding, thereby improving molding efficiency and product quality.

[0050] The switch device 56 controls the circulation and storage of heat. The square tube 561 is connected to the hollow ring 52. The sliding block 563 slides in the square tube 561. The limit rod 565 slides in the fixed sleeve 566. The tension spring 567 provides a reset force. When it is necessary to strengthen convection, the openings at both ends of the gas storage tube 543 are opened through the linkage device 58, that is, the connection hole 562 position. The fixed shaft 581 of the linkage device 58 is fixed to the inner wall of the L-shaped plate 553. The notched plate 582, the sliding shaft 583, the rotating ring 584, the rotating rod 585 and the pushing ring 586 cooperate with each other. When the adjusting device 55 moves downward, it is driven by the fixed shaft 581. When the notch plate 582 moves, since the rotation position of the rotating rod 585 is fixed, when the sliding shaft 583 slides in the notch plate 582, it will drive the rotating ring 584 to rotate, and then drive the rotating rod 585 to rotate. The synchronously rotating pushing ring 586 will generate a pushing force on the limit rod 565 of the switch device 56, thereby pushing the blocking device 564 away from the position of the connecting hole 562, thereby opening the passage of the gas storage pipe 543. The transmission of the linkage device 58 makes the movements of the various components more coordinated, and can remove the obstruction to the ventilation groove 57 while also removing the obstruction to the ventilation pipe, thereby improving the stability of the entire heat preservation device 5;

[0051] The sliding block 563 moves in the square tube 561, opening the connecting hole 562, so that heat can flow smoothly. The fixed block 5641 of the blocking device 564 is fixed on the sliding block 563. The damping rod 5642, the return spring 5643 and the movable column 5644 cooperate with each other. When the movable column 5644 is subjected to external force, it retracts into the fixed block 5641 and slides along the axial direction of the damping rod 5642, compressing the return spring 5643 to realize the opening and closing control of the circulation channel. When heat enters the movable box 53, the switch device 56 opens the circulation channel and stores the heat in the gas storage pipe 543. The switch device 56 is closed after the heat stabilizes. After the injection molding is completed, the switch device 56 and the L-shaped plate 553 of the movable adjustment device 55 are opened again to release the gas in the gas storage pipe 543, so that the internal convection is resumed, thereby slowing down the speed of heat loss inside the mold, thereby achieving the heat preservation function, reducing heat loss and reducing energy consumption.

[0052] The protective frame 541 of the positioning device 54 is internally provided with a reflective coating 542 and a gas storage tube 543. The reflective coating 542 can reflect heat and reduce heat loss. The gas storage tube 543 is used to store heat. The protective frame 541 is fixedly connected to the inner wall of the wrapping ring 44, further enhancing heat utilization.

[0053] The positioning sleeve 591 of the port protection device 59 is fixed to the inner side wall of the protection frame 541. The elastic sheet 592, the connecting sleeve 593, and the corrugated sleeve 594 cooperate with each other to make the port position of the gas storage pipe 543 pressure-resistant. The elastic sheet 592 and the corrugated sleeve 594 offset the inertial effect caused by the movement of the upper mold base 2, thereby protecting the port of the gas storage pipe 543 and preventing impurities from entering the gas storage pipe 543 and affecting heat storage and transmission. At the same time, it also protects the internal structure of the mold and maintains its stability.

[0054] The carbon fiber composite material forming mold with thermal insulation function realizes the thermal insulation and forming functions through the close cooperation of various devices. The connecting device 4 and the thermal insulation device 5 work together to control the conduction, circulation and storage of heat, meeting the temperature requirements during the carbon fiber composite material forming process. The adjustable design of the regulating device 55 and the switching device 56 improves the energy utilization efficiency. The positioning device 54 and the port protection device 59 ensure the normal operation of the device. The linkage device 58 enhances the coordination between the components.
