[0023] For further information, see Figure 8 - Fig. 9, a material unloading assembly 8 is used to assist in unloading products. The material unloading assembly 8 includes two slide bars 81, both of which are connected to the bottom of the press table 3. The two slide bars 81 are slidably connected to the operating table 1. A roller 82 is connected between the two slide bars 81. A slide shaft 83 is slidably installed on the bottom surface of the operating table 1 through a bracket. One end of the slide shaft 83 is connected to a slide slot frame 84. The slide slot frame 84 is provided with two inclined slots. The bottom of the inclined slot of the slide slot frame 84 is provided with an opening. During the movement of the roller 82, it slides in contact with the two inclined slots of the slide slot frame 84. The roller 82 slides in contact with the two inclined slots of the slide slot frame 84. During the process of moving from bottom to top, the roller 82 enters the two inclined slots through the openings at the bottom of the two inclined slots of the slide slot frame 84. During the subsequent upward movement of the roller 82, the roller 82 drives the slide slot frame 84 to move backward through the two inclined slots. When the roller 82 moves from top to bottom, it drives the slide slot frame 84 to move forward and reset through the two inclined slots. The other end of the slide shaft 83 is connected to a connecting frame 85. The bottom surface of the operating table 1 is rotatably mounted with a pry bar 86. Two mounting frames 87 are mounted on the operating table 1. 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 through a sliding hinge, and the top end of the pry bar 86 is connected to the material box 88 through a sliding hinge. The connecting frame 85 moves forward and uses the lever principle to drive the material box 88 to move backward on the two mounting frames 87 through 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 through the pry bar 86. During the movement, the material box 88 is located below the male mold 4. When the pressing table 3 drives the male mold 4 to move upward into place, the material box 88 moves to the bottom of the male mold 4. At this time, the male mold 4 uses its internal The ejection mechanism ejects the material, and the material falls into the material box 88. When the press table 3 and the male mold 4 move down again, the material box 88 drives the material to move forward and leave the movement track of the press table 3 and the male mold 4, and the staff takes out the processed material from the material box 88; through the setting of the unloading component 8, after the material processing is completed, the material box 88 can automatically move backward to catch the falling material, and then drive the material to move forward, which is convenient for the staff to take out the material, optimizes the unloading process, and avoids the safety risks of the staff taking materials under the press table 3.

[0024] Further, see Fig.10 - Fig.12, a curing assembly 9 is used to cure the master mold 6. Two curing assemblies 9 are provided. The two curing assemblies 9 are respectively arranged on one side of the two infrared heaters 10 close to the installation box 2. The curing assembly 9 includes a rotating rod 91. The rotating rod 91 is rotatably installed on the outer wall of one side of the infrared heater 10 close to the installation box 2. A brush 92 is connected to the bottom of the rotating rod 91. A connecting block 93 is connected to the bottom of the rotating rod 91. A curved block 94 is hinged at the bottom of the connecting block 93. A limiting rod 95 is connected to the outer wall of the connecting block 93. The limiting rod 95 abuts against the curved block 94. Since the limiting rod 95 limits 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 close to the installation box 2 is connected There is a supporting rod 96, which is in contact with the bottom of the rotating rod 91. Both sides of the mother mold 6 are connected with a resistance rod 97, which contacts the curved surface block 94 when moving, and contacts the brush 92 when the mother mold 6 moves. The brush 92 contacts the cavity of the mother mold 6 when the mother mold 6 moves, and cleans the cavity of the mother mold 6 to maintain the cleanliness of the cavity of the mother mold 6. When the resistance rod 97 contacts the curved surface of the curved surface block 94, the resistance rod 97 moves the curved surface block 94 upward along the curved surface of the curved surface block 94, so that the rotating rod 91 and the brush 92 swing upward, so that the brush 92 avoids the material on the mother mold 6 to prevent the brush 92 from causing the material to deviate; the maintenance 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, and a fan-shaped block 911 is connected to the outer wall of the mother mold 6. The fan-shaped block 911 contacts the air cylinder 99 during the movement. When the fan-shaped block 911 contacts the air cylinder 99, the fan-shaped block 911 squeezes the air cylinder 99, so that the air cylinder 99 injects air into the liquid box 98. Two liquid pipes 910 are respectively installed on both sides of the rotating rod 91. One end of the liquid pipe 910 is connected to the liquid box 98. The liquid box 98 uses the positive pressure principle to send the dry lubricant inside it to the two liquid pipes 910. The other end of the liquid pipe 910 is provided 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 on the surface of the material. The dry lubricant can improve the lubricity of the cavity surface, making demolding easier, while reducing the friction of the resin flowing in the cavity, optimizing the injection molding effect, and also maintaining the master mold 6 and the male mold 4 to extend their service life. By setting the maintenance component 9, after the master mold 6 is demolded, the brush 92 can clean the cavity of the master mold 6 to avoid impurities adhering to the cavity and affecting the subsequent processing quality. The brush 92 can also automatically avoid the material on the master mold 6 to avoid material displacement. By setting the liquid tank 98, the two atomizing nozzles can spray the dry lubricant on the cavity surface of the master mold 6 and the top surface of the material, thereby optimizing the molding injection molding effect, facilitating demolding, and maintaining the male mold 4 and the master mold 6. Example

[0025] A carbon fiber compression molding and injection molding integrated molding method, using a carbon fiber compression molding and injection molding integrated molding device in Example 1, further comprising the following steps: Step 1: Place the material into the mother mold 6 located below the infrared heater 10, and the extruder heat-melts the resin; Step 2: Start the infrared heater 10 to heat the material; Step 3: The press table 3 moves upward, and the heated female mold 6 and the material are moved to the bottom of the male mold 4; Step 4: the press table 3 moves downward, and the male mold 4 molds 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; Step 5: After the molding is completed, the extruder injects the resin into the male mold 4 through the injection pipeline 5 for injection molding; Step 6: After the injection molding is completed, the press table 3 moves up, and another material moves to the bottom of the male mold 4 to wait for molding and injection molding. The staff removes the injection-molded product and prepares to place the next processing material; Step 7: Repeat the above steps and perform cyclic alternating operations.

[0026] With the above structure, the working principle of this case is that the hydraulic device in the installation box 2 can drive the press table 3 to move up and down, and the press table 3 drives the male mold 4 to move down and close the mold with the female mold 6 to mold the material. The infrared heater 10 can heat the material. The injection molding pipeline 5 can inject the resin extruded by the extruder into the male mold 4. After the molding is completed, the injection molding operation is performed by injecting the resin, thereby achieving the effect of molding and injection molding in one step, reducing the production process and improving the work efficiency. When the press 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 ratchet tooth ring 76 to reciprocate. The ratchet tooth ring 76 cooperates with the ratchet wheel of the rotating shaft 73 through the two ratchets inside it, so that the ratchet tooth ring 76 can drive the rotating shaft 73 to rotate 180 times during the reciprocating rotation. When the pressing platform 3 drives the rack 75 to move upward, the rack 75 drives the rotating shaft 73 to rotate 180 degrees through the ratchet tooth ring 76. When the rotating shaft 73 rotates, it drives the residual gear 74 to rotate. During the process of the residual gear 74 rotating one circle, a set of teeth of the residual gear 74 will successively mesh with the two sets of teeth of the elliptical ring 72. Since the two sets of teeth of the elliptical ring 72 are respectively located above and below the residual gear 74, the residual gear 74 will first drive the elliptical ring 72 to move left during the first 180 degrees of rotation, and the residual gear 74 will drive the elliptical ring 72 to move right during the second 180 degrees of rotation. The residual gear 74 can drive the elliptical ring 72 to move back and forth once when rotating one circle, and the pressing platform 3 can drive the residual gear 74 through the rack 75 when moving upward. The gear 74 rotates 180 degrees, and the elliptical ring 72 drives the slide 71 to move synchronously when it moves. Therefore, when the press table 3 moves downward, the slide 71 does not move. When the press table 3 moves upward, the slide 71 moves to the left. When the press table 3 moves upward for the second time, the slide 71 moves to the right. When the press table 3 moves upward for the third time, the slide 71 moves to the left. And so on. When the slide 71 moves, it drives the two mother molds 6 to move synchronously, so that the two mother molds 6 move alternately to the bottom of the male mold 4. The two mother molds 6 also move alternately to the bottom of the two infrared heaters 10. When one of the mother molds 6 and the male mold 4 is performing molding and injection molding, the other mother mold 6 is located under the infrared heater 10 for loading and heating. The two infrared heaters 10 and the two mother molds 6 perform the loading and heating working steps alternately. The working efficiency is improved, and the interval time between two heating operations of the infrared heater 10 is extended, so that the infrared heater 10 can get sufficient rest and heat dissipation, and the same infrared heater 10 is prevented from overheating due to long-term high-frequency operation, which affects the service life; through the setting of the male mold 4, the two female molds 6, the two infrared heaters 10 and the switching component 7, the two female molds 6 are coordinated with the male mold 4 in turn to achieve the effect of molding and injection molding in one step, reduce the operation steps, and improve the working efficiency; the two female molds 6 and the two infrared heaters 10 alternately perform the working steps of loading and heating materials, save working time, speed up the working frequency, and at the same time avoid overloading the same infrared heater 10 due to long-term use, which affects the service life.

[0027] When the press table 3 moves up and down, it drives the two slide bars 81 to move up and down synchronously. The two slide bars 81 can play a certain limiting role, thereby improving the stability of the press table 3 and improving the mold clamping accuracy. When the two slide bars 81 move, they drive the rollers 82 to move up and down. During the process of the rollers 82 moving from bottom to top, they enter the two inclined slots through the openings at the bottom of the two inclined slots of the slide slot frame 84. In the subsequent process of the rollers 82 moving upward, the rollers 82 drive the slide slot frame 84 to move backward through the two inclined slots. When the rollers 82 move from top to bottom, they drive the slide slot frame 84 to move forward and reset through the two inclined slots. Then the rollers 82 disengage from the two inclined slots through the openings. When the slide slot frame 84 moves, it can drive the slide shaft 83 and the connecting frame 85 to move synchronously. Therefore, when the press table 3 moves up and is about to move up to the position, the connecting frame 85 moves forward. When the press table 3 starts to move down, the connecting frame 85 moves backward, and the connecting frame 85 moves forward. The lever principle is used to drive the material box 88 to move backward on the two mounting frames 87 through the pry bar 86. When the connecting frame 85 moves backward, the lever principle is used to drive the material box 88 to move forward through the pry bar 86. Therefore, when the pressing table 3 drives the male mold 4 to move upward into place, the material box 88 moves to the bottom of the male mold 4. At this time, the male mold 4 uses its internal ejection mechanism to eject the material, and the material falls into the material box 88. When the pressing table 3 and the male mold 4 move downward again, the material box 88 drives the material to move forward and leaves the movement trajectory of the pressing table 3 and the male mold 4. The staff takes out the processed material in the material box 88; through the setting of the unloading component 8, after the material processing is completed, the material box 88 can automatically move backward to catch the falling material, and then drive the material to move forward, which is convenient for the staff to take out the material, optimizes the unloading process, and avoids the safety risks of the staff taking materials under the pressing table 3.

[0028] Taking the right maintenance component 9 as an example, when the mother mold 6 moves to the right, it drives the two resistance rods 97 and the fan-shaped block 911 above it to move synchronously. The resistance rod 97 on the right first contacts the curved surface block 94. Since the limit rod 95 limits the curved surface block 94 and the connecting block 93, the curved surface block 94 can only swing to the right but not to the left. After the resistance rod 97 contacts the curved surface block 94, the curved surface block 94 is pushed to the right to rotate the curved surface block 94. Subsequently, the curved surface block 94 slides over the top edge of the mother mold 6 and the resistance rod 97 on the left. During this process, the brush 92 contacts the cavity of the mother mold 6 to clean the cavity of the mother mold 6 and maintain the cleanliness of the cavity of the mother mold 6. Subsequently, the mother mold 6 moves to the bottom of the infrared heater 10 on the right. The operator installs new material. When the mother mold 6 starts to move to the left, the resistance rod 97 on the left contacts the curved surface of the curved block 94. Since the curved block 94 cannot swing to the left, the resistance rod 97 pushes the curved block 94 upward along the curved surface of the curved block 94. When 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 mother mold 6 and the resistance rod 97 on the right. During this process, the rotating rod 91 and the brush 92 remain in a lifted state, so that the brush 92 does not contact the mother mold 6 and the material above it, so as to avoid the brush 92 driving the material to deviate. When the curved block 94 is not in contact with the resistance rod 97 and the mother mold 6, the curved block 94, the rotating rod 91 and the brush 92 are Falling due to gravity, the rotating rod 91 falls on the supporting rod 96, and the brush 92 generates a certain vibration, thereby shaking off the impurities attached to its surface to maintain the cleanliness of the brush 92; the liquid tank 98 is filled with dry lubricant, and when the mother mold 6 moves to the left and to the right, the fan-shaped block 911 will come into contact with the air cylinder 99 once. When the fan-shaped block 911 contacts the air cylinder 99, the fan-shaped block 911 squeezes the air cylinder 99, so that the air cylinder 99 injects air into 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, so that when the mother mold 6 moves to the right, the two liquid pipes 910 spray the dry lubricant into the cavity of the mother mold 6 below through two atomizing nozzles. When the mother mold 6 moves to the left with the material, the dry and wet lubricants The lubricant is sprayed on the surface of the material, and then 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 lubricity of the cavity surface, facilitate demoulding, and at the same time 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 the service life; through the setting of the maintenance component 9, the brush 92 can clean the cavity of the female mold 6 after the female mold 6 is demoulded to avoid impurities 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 on the cavity surface of the female mold 6 and the top surface of the material, which optimizes the molding injection molding effect, facilitates demoulding, and maintains the male mold 4 and the female mold 6.
