In the production of carbon fiber composite parts, pre-formed carbon fiber material is placed into a mold, and a certain pressure and temperature are applied by a molding machine to cure the resin matrix and bond the carbon fibers together to form a part with a certain shape and performance. Then, the fiber preform is placed into the mold cavity, and after the mold is closed, resin is injected into the mold through an injection molding machine, so that the resin penetrates into the fiber preform under a certain pressure, and then it is cured and formed at a certain temperature.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Example
[0043] Please see Figure 1 - Figure 7A carbon fiber compression molding and injection molding integrated molding equipment includes an operating table 1, an installation box 2 mounted on the operating table 1, a hydraulic device inside the installation box 2, and a pressure table 3 connected to the output end of the hydraulic device inside the installation box 2. The hydraulic device inside the installation box 2 can drive the pressure table 3 to move up and down. A male mold 4 is connected to the bottom of the pressure table 3. An injection line 5 is installed on the installation box 2. One end of the injection line 5 is connected to an extruder, and the other end of the injection line 5 is connected to the male mold 4. The injection line 5 can inject the resin extruded by the extruder into the male mold 4. After compression molding is completed, injection molding is performed by injecting resin, realizing the effect of compression molding and injection molding in one step, reducing production steps and improving work efficiency. Two infrared heaters 10 are installed on the operating table 1, and the two infrared heaters 10 are located on both sides of the installation box 2. The infrared heaters 10 can heat the material.It also includes two female molds 6 and a switching assembly 7 for cyclical alternation. The switching assembly 7 includes a slide table 71, which is slidably mounted on the inner wall of the top surface of the operating table 1. Both female molds 6 are mounted on the slide table 71. During movement, the two female molds 6 are respectively located below the infrared heater 10. During movement, the two female molds 6 are alternately located below the male mold 4. An elliptical ring 72 is connected to the bottom surface of the slide table 71. A rotating shaft 73 is rotatably mounted on the bottom surface of the operating table 1 via a bracket. A residual gear 74 is connected to the outer wall of the rotating shaft 73. Two sets of teeth are respectively provided on the upper and lower inner sides of the elliptical ring 72. A set of teeth is provided on the residual gear 74. When the set of teeth of the residual gear 74 rotates, it alternately interacts with the elliptical ring 72. The two sets of teeth of the circular ring 72 mesh. During one revolution of the residual gear 74, one set of teeth of the residual gear 74 will successively mesh with the two sets of teeth of the elliptical ring 72. This causes the residual gear 74 to first drive the elliptical ring 72 to move to the left during the first 180-degree rotation, and then drive the elliptical ring 72 to move to the right during the second 180-degree rotation. The outer wall of the pressure table 3 is connected to a rack 75, and the outer wall of the rotating shaft 73 is rotatably connected to a pawl ring 76. The outer wall of the pawl ring 76 meshes with the rack 75, and the inner wall of the pawl ring 76 is provided with two pawls. The outer wall of the rotating shaft 73 is provided with a ratchet, and the two pawls of the pawl ring 76 mesh with the ratchet of the rotating shaft 73. The pawl ring 76, through its two internal pawls and the ratchet of the rotating shaft 73, enables the rotating shaft 73 to rotate 180 degrees during its reciprocating rotation. When the slide table 71 moves, it drives the two female molds 6 to move synchronously, causing them to alternately move to the area below the male mold 4 and also alternately move to the area below the two infrared heaters 10. While one female mold 6 and the male mold 4 are undergoing molding and injection, the other female mold 6, located below the infrared heater 10, is being fed and heated. This alternating feeding and heating process between the two infrared heaters 10 and the two female molds 6 improves work efficiency and extends the lifespan of the infrared heaters 10 during the two heating cycles. The interval between hot work operations allows the infrared heater 10 to rest and dissipate heat fully, preventing overheating caused by prolonged high-frequency operation of the same infrared heater 10, which would affect its service life. Through the arrangement of the male mold 4, two female molds 6, two infrared heaters 10, and the switching component 7, the two female molds 6 alternately cooperate with the male mold 4, achieving a one-step molding and injection molding effect, reducing operation steps and improving work efficiency. The alternating feeding and heating of materials by the two female molds 6 and the two infrared heaters 10 saves working time, increases the working frequency, and also avoids overloading the same infrared heater 10 due to prolonged use, which would affect its service life.
[0044] Furthermore, please refer to Figure 8 - Figure 9The unloading assembly 8 is used to assist in product unloading. The unloading assembly 8 includes two slide rods 81, both connected to the bottom of the pressure table 3. The two slide rods 81 are slidably connected to the operating table 1. A roller 82 connects the two slide rods 81. A slide shaft 83 is slidably mounted on the bottom surface of the operating table 1 via a bracket. One end of the slide shaft 83 is connected to a slide rail frame 84. The slide rail frame 84 has two inclined grooves, and the bottom of the inclined grooves of the slide rail frame 84 has an opening. During movement, the roller 82 slides in contact with the two inclined grooves of the slide rail frame 84. 2. During the upward movement, the roller 82 enters the two inclined grooves through the openings at the bottom of the two inclined grooves of the slide frame 84. As the roller 82 moves upward, it drives the slide frame 84 backward through the two inclined grooves. When the roller 82 moves downward, it drives the slide frame 84 forward to reset through the two inclined grooves. The other end of the slide shaft 83 is connected to a connecting frame 85. A pry bar 86 is rotatably mounted on the bottom surface of the operating table 1 via a bracket. Two mounting frames 87 are mounted on the operating table 1, and a material box 88 is slidably mounted between the two mounting frames 87. The bottom end of the pry bar 86 is connected to the connecting frame 85 via a sliding hinge, and the top end of the pry bar 86 is connected to the material box 88 via a sliding hinge. When the connecting frame 85 moves forward, it uses the lever principle to drive the material box 88 to move backward on the two mounting brackets 87 via the pry bar 86. When the connecting frame 85 moves backward, it uses the lever principle to drive the material box 88 to move forward via the pry bar 86. During the movement, the material box 88 is located below the male mold 4. When the pressure table 3 drives the male mold 4 to move upward into place, the material box 88 moves to below the male mold 4. At this time, the male mold 4 utilizes its internal... The ejection mechanism ejects the material, which falls into the material box 88. When the pressure table 3 and the male mold 4 move down again, the material box 88 moves the material forward, away from the movement trajectory of the pressure table 3 and the male mold 4. The operator then removes the processed material from the material box 88. Through the setting of the feeding component 8, after the material is processed, the material box 88 can automatically move backward to catch the falling material, and then move the material forward, making it easier for the operator to remove the material. This optimizes the feeding process and avoids the safety risks of the operator retrieving the material from under the pressure table 3.
[0045] Furthermore, please refer to Figure 10 - Figure 12The curing component 9 is used to cure the master mold 6. Two curing components 9 are provided, each located on one side of the two infrared heaters 10 near the mounting box 2. Each curing component 9 includes a rotating rod 91, which is rotatably mounted on the outer wall of the infrared heater 10 near the mounting box 2. A brush 92 is connected to the bottom of the rotating rod 91, and a connecting block 93 is also connected to the bottom of the rotating rod 91. A curved block 94 is hinged to the bottom of the connecting block 93. A limiting rod 95 is connected to the outer wall of the connecting block 93, and the limiting rod 95 abuts against the curved block 94. Because the limiting rod 95 limits the movement of the curved block 94 and the connecting block 93, the curved block 94 can only swing in one direction. The outer wall of the infrared heater 10 near the mounting box 2 is connected to... The system includes a support rod 96, which abuts against the bottom of a rotating rod 91. Two contact rods 97 are connected to both sides of the female mold 6. During movement, the contact rods 97 contact the curved block 94, and the female mold 6 contacts the brush 92. The brush 92 contacts the cavity of the female mold 6 during movement, cleaning the cavity and maintaining its cleanliness. When the contact rod 97 contacts the curved surface of the curved block 94, it pushes the curved block 94 upwards, causing the rotating rod 91 and brush 92 to swing upwards. This allows the brush 92 to avoid material on the female mold 6, preventing the brush 92 from causing material displacement. The curing component 9 also includes a liquid tank 98, which is installed on the operating table 1. An air cylinder 99 is installed on the box 98. A sector block 911 is connected to the outer wall of the mother mold 6. During movement, the sector block 911 contacts the air cylinder 99. When the sector block 911 contacts the air cylinder 99, it squeezes the air cylinder 99, causing the air cylinder 99 to inject air into the liquid tank 98. Two liquid pipes 910 are installed on both sides of the rotating rod 91. One end of the liquid pipe 910 is connected to the liquid tank 98. The liquid tank 98 uses the positive pressure principle to send the dry lubricant inside to the two liquid pipes 910. The other end of the liquid pipes 910 is equipped with an atomizing nozzle. The two liquid pipes 910 spray the dry lubricant into the cavity of the mother mold 6 below through the two atomizing nozzles. When the mother mold 6 moves with the material, the dry and wet lubricants are sprayed onto the surface of the material. Dry lubricant improves the lubrication of the cavity surface, facilitating demolding. It also reduces the friction of resin flow within the cavity, optimizing injection molding. Furthermore, it helps maintain the female mold 6 and male mold 4, extending their service life. The maintenance component 9 allows the brush 92 to clean the cavity of the female mold 6 after demolding, preventing impurities from affecting subsequent processing quality. The brush 92 also automatically avoids material on the female mold 6, preventing material displacement. The liquid tank 98 allows two atomizing nozzles to spray dry lubricant onto the cavity surface of the female mold 6 and the top surface of the material, optimizing the molding injection effect, facilitating demolding, and maintaining the male mold 4 and female mold 6. Example
[0046] A carbon fiber compression molding method, using the carbon fiber compression molding equipment described in Example 1, further includes the following steps:
[0047] Step 1: Place the material into the mold 6 located below the infrared heater 10, and the extruder heat-melts the resin;
[0048] Step 2: Start the infrared heater 10 to heat the material;
[0049] Step 3: The pressure table 3 moves upward, and the heated female mold 6 and the material move to below the male mold 4;
[0050] Step 4: The pressing table 3 moves down, and the male mold 4 presses the material on the female mold 6. At this time, another material is placed on another female mold 6 and heated by another infrared heater 10.
[0051] Step 5: After molding is completed, the extruder injects resin into the male mold 4 through the injection line 5 for injection molding;
[0052] Step Six: After injection molding is completed, the pressure table 3 moves up, and another material moves to the bottom of the mold 4 to wait for molding and injection. The staff removes the finished product and prepares to place the next material for processing.
[0053] Step 7: Repeat the above steps to perform cyclical alternation operations.
[0054] Using the above structure, the working principle of this case is as follows: the hydraulic device inside the mounting box 2 can drive the pressure table 3 to move up and down. The pressure table 3 drives the male mold 4 to move down and close with the female mold 6 to mold the material. The infrared heater 10 can heat the material. The injection line 5 can inject the resin extruded from the extruder into the male mold 4. After molding, the resin injection operation is performed, realizing the effect of molding and injection molding in one step, reducing production steps and improving work efficiency. When the pressure table 3 moves, it drives the rack 75 to move up and down synchronously. When the rack 75 moves up and down, it drives the pawl ring 76 to rotate back and forth. The pawl ring 76, through the cooperation of its two pawls and the ratchet of the rotating shaft 73, can drive the rotating shaft 73 to rotate 180 degrees during the reciprocating rotation of the pawl ring 76. When the pressure table 3 moves upward, the rack 75 drives the rotating shaft 73 to rotate 180 degrees via the pawl ring 76. The rotation of the rotating shaft 73 drives the residual gear 74 to rotate. During one revolution of the residual gear 74, one set of teeth on the residual gear 74 meshes with two sets of teeth on the elliptical ring 72. Since the two sets of teeth on the elliptical ring 72 are located above and below the residual gear 74 respectively, the residual gear 74 will first drive the elliptical ring 72 to the left during the first 180-degree rotation, and then drive it to the right during the second 180-degree rotation. One revolution of the residual gear 74 can drive the elliptical ring 72 to perform one left-right reciprocating movement. Meanwhile, when the pressure table 3 moves upward, it can drive the residual gear 74 to rotate via the rack 75. When gear 74 rotates 180 degrees, the elliptical ring 72 moves, causing the slide 71 to move synchronously. Therefore, when the pressure table 3 moves downward, the slide 71 remains stationary; when the pressure table 3 moves upward, the slide 71 moves to the left; when the pressure table 3 moves upward a second time, the slide 71 moves to the right; when the pressure table 3 moves upward a third time, the slide 71 moves to the left, and so on. The movement of the slide 71 causes the two female molds 6 to move synchronously, causing them to alternately move to the area below the male mold 4. The two female molds 6 also alternately move to the area below the two infrared heaters 10. While one female mold 6 and the male mold 4 are performing molding and injection, the other female mold 6 is located below the infrared heater 10 for material feeding and heating. This alternating feeding and heating process between the two infrared heaters 10 and the two female molds 6... This improves work efficiency and extends the interval between two heating operations of the infrared heater 10, allowing it to rest and dissipate heat effectively. This prevents overheating caused by prolonged high-frequency operation of the same infrared heater 10, which would affect its service life. Through the configuration of the male mold 4, two female molds 6, two infrared heaters 10, and the switching component 7, the two female molds 6 alternately cooperate with the male mold 4, achieving a one-time molding effect of compression and injection molding. This reduces operation steps and improves work efficiency. The alternating feeding and heating of materials by the two female molds 6 and the two infrared heaters 10 saves working time, increases the working frequency, and avoids overloading the same infrared heater 10 due to prolonged use, which would affect its service life.
[0055] When the pressure table 3 moves up and down, it drives the two slide rods 81 to move up and down synchronously. The two slide rods 81 can play a certain limiting role, thereby improving the stability of the pressure table 3 and improving the mold closing accuracy. When the two slide rods 81 move, they drive the rollers 82 to move up and down. During the upward movement of the rollers 82, they enter the two inclined grooves through the openings at the bottom of the two inclined grooves of the slide frame 84. As the rollers 82 move upward, they drive the slide frame 84 to move backward through the two inclined grooves. When the rollers 82 move downward, they drive the slide frame 84 to move forward and reset through the two inclined grooves. Then, the rollers 82 disengage from the two inclined grooves through the openings. When the slide frame 84 moves, it can drive the slide rods 83 and the connecting frame 85 to move synchronously. Therefore, when the pressure table 3 moves upward and is about to move into position, the connecting frame 85 moves forward. When the pressure table 3 begins to move downward, the connecting frame 85 moves backward and forward. The material box 88 is moved backward on the two mounting brackets 87 by lever 86 via pry bar 86. When the connecting bracket 85 moves backward, the material box 88 is moved forward by lever 86 via pry bar 86. Therefore, when the pressure table 3 moves the male mold 4 upward into position, the material box 88 moves below the male mold 4. At this time, the male mold 4 uses its internal ejection mechanism to eject the material, which falls into the material box 88. When the pressure table 3 and male mold 4 move downward again, the material box 88 moves forward with the material, leaving the movement trajectory of the pressure table 3 and male mold 4. The operator can then take out the processed material from the material box 88. Through the setting of the unloading component 8, after the material is processed, the material box 88 can automatically move backward to catch the falling material, and then move the material forward, making it easier for the operator to take out the material. This optimizes the unloading process and avoids the safety risks of the operator taking the material from below the pressure table 3.
[0056] Taking the maintenance component 9 on the right as an example, when the female mold 6 moves to the right, it drives the two abutment rods 97 and the fan-shaped block 911 above it to move synchronously. The abutment rod 97 on the right first contacts the curved block 94. Because the limiting rod 95 limits the curved block 94 and the connecting block 93, the curved block 94 can only swing to the right and not to the left. After the abutment rod 97 contacts the curved block 94, it pushes the curved block 94 to the right, causing the curved block 94 to rotate. Subsequently, the curved block 94 slides over the top edge of the female mold 6 and the abutment rod 97 on the left. During this process, the brush 92 contacts the cavity of the female mold 6 to clean the cavity of the female mold 6 and maintain the cleanliness of the cavity of the female mold 6. Then, the female mold 6 moves to the right below the infrared heater 10. When the operator installs new material, as the master mold 6 begins to move to the left, the left abutment rod 97 contacts the curved surface of the curved block 94. Since the curved block 94 cannot swing to the left, the abutment rod 97 pushes the curved block 94 upward along its curved surface. As the curved block 94 moves upward, it drives the rotating rod 91 and the brush 92 to swing upward. Subsequently, the curved block 94 slides over the top edge of the master mold 6 and the right abutment rod 97. During this process, the rotating rod 91 and the brush 92 remain raised, preventing the brush 92 from contacting the master mold 6 and the material above it, thus avoiding the brush 92 causing the material to shift. When the curved block 94 is no longer in contact with the abutment rod 97 and the master mold 6, the curved block 94, the rotating rod 91, and the brush 92... Under gravity, the rotating rod 91 falls onto the support rod 96, causing the brush 92 to vibrate and shake off impurities, maintaining its cleanliness. The liquid tank 98 contains dry lubricant. When the mold 6 moves left and right, the sector block 911 contacts the air cylinder 99. When the sector block 911 contacts the air cylinder 99, it compresses the cylinder, causing it to inject air into the liquid tank 98. The liquid tank 98 uses positive pressure to deliver the dry lubricant to the two liquid pipes 910. When the mold 6 moves to the right, the two liquid pipes 910 spray the dry lubricant into the cavity of the lower mold 6 through two atomizing nozzles. When the mold 6 moves to the left with the material, the dry and wet lubricants... The dry lubricant is sprayed onto the surface of the material. After the male mold 4 moves down, the dry lubricant adheres to the cavity of the male mold 4. The dry lubricant can improve the lubrication of the cavity surface, making demolding easier. At the same time, it can reduce the friction of the resin flowing in the cavity, optimize the injection molding effect, and also play a role in maintaining the female mold 6 and the male mold 4, extending their service life. Through the setting of the maintenance component 9, the brush 92 can clean the cavity of the female mold 6 after demolding, preventing impurities from adhering to the cavity and affecting the subsequent processing quality. Through the setting of the liquid tank 98, the two atomizing nozzles can spray the dry lubricant onto the cavity surface of the female mold 6 and the top surface of the material, which can optimize the molding injection effect, facilitate demolding, and maintain the male mold 4 and the female mold 6.
