Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of molding machines, more particularly, to a carbon fiber composite material molding machine. BACKGROUND

[0002] Carbon fiber composite material is a composite material composed of carbon fiber and matrix material. Carbon fiber is usually made of polypropylene or other carbides as raw material, and is obtained by high-temperature carbonization treatment. It has very high strength and stiffness. The matrix material is usually resin, such as epoxy resin, polyimide resin, etc., which is used to fix and support carbon fiber and form the overall structure of the composite material.

[0003] Molding machine is a machine widely used in manufacturing industry, which is mainly used to process workpieces or plates into different shapes, sizes and surface quality of finished products. It is widely used in metal processing, plastic processing, composite material processing and other industries, and can realize this goal through extrusion, stretching, blanking and other processing operations. The working principle of molding machine mainly includes three steps: first, the workpiece or raw material is placed between the upper and lower dies to form a closed mold cavity; then, the workpiece or raw material in the mold cavity is heated and melted (for plastic processing) or directly extruded (for metal or composite material processing) by the heating system; finally, the workpiece or raw material in the mold cavity is pressurized by the hydraulic system to fill the entire mold cavity and form a complete finished product. Molding machine has many types, including manual molding machine and hydraulic molding machine. Manual molding machine mainly relies on manual operation, which is suitable for small-scale processing work, has small size and low price, and is easy to operate. Hydraulic molding machine uses hydraulic system for power transmission to provide greater processing force and higher processing efficiency, which is suitable for some small and medium-sized molding processing tasks.

[0004] During the molding process of carbon fiber composite material, due to the inconsistent heating capacity of each part of the heating plate on the molding machine, the interlayer shielding effect, and the different heat dissipation capacity of the outer edge and the inner part, it is easy to cause the temperature of the two sides near the heating plate to be too high, the temperature of the middle part to be too low, the temperature of the outer layer to be too high, and the temperature of the inner layer to be too low.

Heat-conducting wires 93 are fixedly connected between the multiple thermostatic plates 92. Multiple uniformly distributed electromagnetic blocks 94 are fixedly connected in the middle of the pressure-resistant base plate 91. The heating plate 9 is staggered with multiple constant temperature plates 92, which can evenly distribute the heat of the heating plate. During the heating and molding process, the heat-conducting wire 93 transfers some of the heat from the high-temperature constant temperature plate 92 to the low-temperature constant temperature plate 92, thereby making the overall surface temperature of the temperature control base plate 9 uniform. Meanwhile, the electromagnetic block 94 is connected to the electric field and magnetized to attract the reduced iron powder in the hot melt bag 81, thereby attracting the multiple composite material balls 8 to the upper end of the temperature control base plate 9, which corresponds to the multiple electromagnetic blocks 94, so that the multiple composite material balls 8 are evenly and stably distributed, improving the molding effect.

[0041] Please continue reading. Figures 1-2 An infrared sensor 10 is fixedly connected to the inner wall of the molding machine box 2 on the side away from the conveyor belt 3, and an auxiliary fan 11 is fixedly connected to the inner wall of the molding machine box 2 on the side closer to the conveyor belt 3. The auxiliary fan 11 is electrically connected to the infrared sensor 10. When the carbon fiber fabric is fed by the conveyor belt 3, it falls at an angle. When the infrared sensor 10 senses the falling carbon fiber fabric, it starts the auxiliary fan 11 to blow out air to change the angle of the carbon fiber fabric, so that the carbon fiber fabric can fall horizontally to the top of the temperature control base plate 9. Here, the auxiliary fan 11 is started only briefly.

[0042] A control display screen 12 is fixedly connected to the front end of the molding machine housing 2. The control display screen 12 can be used to control the overall operation and observe the working status of the molding machine.

[0043] Working principle:

[0044] Please see Figures 1-8When the carbon fiber cloth is put on the conveying belt 3, it falls obliquely, and when the infrared sensor 10 senses the falling of the carbon fiber cloth, the auxiliary fan 11 is started to blow air to change the obliquity of the carbon fiber cloth, so that the carbon fiber cloth can fall horizontally on the upper end of the temperature control bottom plate 9. Then, the electric control sliding rail 13 controls the movement of the adjusting slide rod 14, so that the discharging box 15 moves above the carbon fiber cloth and is put by the inner putting cylinder 7. The composite material balls 8 filled in the cylinder 71 are pushed by the rotating plate 72 and fall from the lower through hole 73, so as to be uniformly put. When the composite material balls 8 fall on the upper end of the temperature control bottom plate 9, the electromagnetic blocks 94 are connected to the power supply and magnetically attract the reducing iron powder in the hot melt capsule 81, so as to attract the plurality of composite material balls 8 on the upper end of the temperature control bottom plate 9 by the plurality of electromagnetic blocks 94, so that the plurality of composite material balls 8 are uniformly distributed. After the plurality of composite material balls 8 are covered by the carbon fiber cloth conveyed by the conveying belt 3, the electric control sliding rail 13 controls the adjusting slide rod 14 to reset the discharging box 15, so that the power cylinder 4 is located above the carbon fiber cloth, and the power cylinder 4 is started to move the upper mold pressing plate 5 downward to perform mold pressing. After the mold is heated and pressed by the heating plate, the reducing iron powder is oxidized and reduced to release a large amount of heat after the polyethylene wax in the hot melt capsule 81 is melted, so as to make the carbon fiber composite material radiate heat from inside to outside during mold pressing, and when the pressure is received, the plurality of auxiliary balls 83 are uniformly dispersed after being pressed. When the mold is heated and pressed by the heating plate, the heat of part of the high-temperature constant temperature sheet 92 is transmitted to the low-temperature constant temperature sheet 92 by the heat-conducting wire 93, so as to make the overall temperature of the surface of the temperature control bottom plate 9 uniform, so that the carbon fiber cloth and the composite material balls 8 are uniformly heated.

[0045] From the above technical solution, the present application has the following beneficial effects:

[0046] The present application can achieve uniform heating when the carbon fiber cloth is laid on the upper end of the temperature control bottom plate 9 and combined with the plurality of composite material balls 8 for mold pressing. The plurality of electromagnetic blocks 94 correspondingly attract the plurality of composite material balls 8, so that the plurality of composite material balls 8 are uniformly laid on the upper end of the temperature control bottom plate 9. The local high temperature is uniformly dispersed by the plurality of constant temperature sheets 92, and the local low temperature is assisted by the temperature of other constant temperature sheets 92, so as to make the temperature of the end surface of the temperature control bottom plate 9 uniform, so that the outer surface of the carbon fiber cloth is uniformly heated. The composite material balls 8 not only provide other materials conducive to synthesis for the carbon fiber composite material, but also provide heat from inside to outside, so that the carbon fiber composite material is uniformly heated as a whole during mold pressing, thereby effectively improving the mold pressing of the carbon fiber composite material.
