Description

Technical Field

[0001] The invention relates to the technical field of molding machines, and more particularly to a molding machine for carbon fiber composite materials. Background Art

[0002] Carbon fiber composites are a type of composite material consisting of carbon fibers and matrix materials. Carbon fibers are usually made from carbides such as polypropylene and are obtained through high-temperature carbonization. They have extremely high strength and stiffness. The matrix material is usually a resin, such as epoxy resin, polyimide resin, etc., which is used to fix and support the carbon fibers and form the overall structure of the composite material.

[0003] A die press is a widely used machine in the manufacturing industry. Its main function is to process workpieces or plates into finished products of different shapes, sizes and surface qualities. It is widely used in industries such as metal processing, plastic processing, and composite material processing, and can achieve this goal through processing operations such as extrusion, stretching, and punching. The working principle of a die press is mainly divided into three steps: first, the workpiece or raw material is placed between the upper and lower templates 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) through a heating system; finally, the workpiece or raw material in the mold cavity is pressurized through a hydraulic system to fill the entire mold cavity and form a complete finished product; There are many types of die presses, including manual die presses and hydraulic die presses. Manual die presses are mainly operated by manpower and are suitable for small processing operations. They have a small size, a low price, and are easy to operate; while hydraulic die presses use a hydraulic system for power transmission to provide greater processing force and higher processing efficiency, and are suitable for some small and medium-sized die pressing tasks.

[0004] During the molding process of carbon fiber composite materials, the heating capacity of the heating plate on the molding machine is inconsistent, and it is affected by the shielding effect between layers, as well as the different heat dissipation capacity between the outer edge and the interior.

The upper end of the main control box 1 is fixedly connected to a molding machine case 2, and the main control box 1 and the molding machine case 2 are integrally formed. The side end of the molding machine case 2 is fixedly connected to a conveyor belt 3, and the conveyor belt 3 extends into the molding machine case 2. An electric control slide rail 13 is fixedly connected to the inner wall of the molding machine case 2. An adjusting slide rod 14 is slidably connected to the lower end of the electric control slide rail 13. The lower ends of the adjusting slide rod 14 are respectively fixedly connected to a power cylinder 4 and a discharge box 15. The lower end of the power cylinder 4 is fixedly connected to an upper molding plate 5. The adjusting slide rod 14 is moved by controlling the electric control slide rail 13 to switch the power cylinder 4 and the discharge box 15.

[0023] See also Figure 4 The discharge box 15 includes a storage bin 151, which is fixedly connected to the lower end of the adjusting slide rod 14, and a mounting bin 152 is fixedly connected to the lower end of the storage bin 151, and the storage bin 151 is communicated with the mounting bin 152, and a plurality of composite material balls 8 are stored through 151, and the storage bin 151 replenishes the composite material balls 8 for the mounting bin 152, and the mounting bin 152 releases the composite material balls 8.

[0024] See also Figure 2 A lower mold plate 6 is fixedly connected between the main control box 1 and the molding machine box 2. A plurality of evenly distributed temperature sensors are installed inside and outside the lower mold plate 6. A lower mold groove is opened at the upper end of the lower mold plate 6. The temperature control bottom plate 9 is fixedly connected to the inner end of the lower mold groove. A heating plate is fixedly connected to one end of the upper mold pressing plate 5 and the lower mold plate 6 close to each other. The temperature distribution can be monitored in real time by using the temperature sensor. Through these data, the working parameters of the heating plate can be adjusted in time to maintain the temperature uniformity.

[0025] See also Figure 3-4, multiple composite balls 8 are arranged in a storage bin 151, and multiple delivery cylinders 7 are fixedly installed in the installation bin 152, and the delivery cylinder 7 is communicated with the storage bin 151, and the carbon fiber cloth is transported to the molding machine box 2 through the conveyor belt 3, and falls into the lower mold groove at the upper end of the temperature-controlled bottom plate 9, and then the electric control slide rail 13 moves the discharge box 15 to the top of the carbon fiber cloth, and starts the delivery cylinder 7 inside it to deliver multiple composite balls 8 to the upper end of the carbon fiber cloth, and then the electric control slide rail 13 controls the discharge box 15 to reset, so that the power cylinder 4 moves to the upper end of the carbon fiber cloth, and uses the conveyor belt 3 to transport the carbon fiber cloth for the second time to cover the multiple composite balls 8, and then starts the power cylinder 4 to move the upper mold plate 5 downward for molding.

[0026] See also Figure 5 The delivery cylinder 7 includes a cylinder 71, which is fixedly installed at the inner end of the installation bin 152. The inner end of the cylinder 71 is rotatably connected to a rotating plate 72. Through holes 73 are provided at both the upper and lower ends of the cylinder 71. The rotating plate 72 is rotated to move the composite material balls 8 filled in the cylinder 71 and fall from the through holes 73 below, so as to be evenly delivered.

[0027] See also Figure 6 The composite material ball 8 includes a hot melt capsule 81, which is arranged in the storage bin 151. The inner end of the hot melt capsule 81 is filled with a molding material 82. The molding material is made of polymer resin. The hot melt capsule 81 is made of a mixture of reducing iron powder and polyethylene wax material. The reducing iron powder is in contact with air to undergo an oxidation-reduction reaction to release a large amount of heat, so that the carbon fiber composite material dissipates heat from the inside to the outside during molding. When pressure is received, multiple auxiliary material balls 83 are evenly dispersed after being compressed, and the reducing iron powder content is relatively small. The residual product after the reduction reaction is wrapped by the molding material 82 and the material in the auxiliary material ball 83, thereby weakening its magnetic attraction performance or even blocking it, so that the carbon fiber composite material does not have magnetic attraction performance. Here, polyethylene wax can improve wear resistance, skid resistance and smoothness. It can be used as an auxiliary material in carbon fiber composite materials without having a significant impact on the resin matrix. At the same time, it also improves the wear resistance, skid resistance and smoothness of the carbon fiber composite material.

[0028] Polyethylene wax can also be replaced by polypropylene film. Polypropylene film has good hot melt properties and can be used in applications such as packaging, sealing and covering. When in contact with carbon fiber composites, polypropylene film usually does not cause chemical reactions or affect the performance of the composites; polyamide film, polyamide film is a high-performance thermoplastic film with good hot melt properties and mechanical properties. When in contact with carbon fiber composites, polyamide film usually does not cause adverse reactions with the resin matrix; polytetrafluoroethylene film, polytetrafluoroethylene film has excellent high temperature resistance and corrosion resistance, and is usually used in applications such as packaging, coating and isolation. When in contact with carbon fiber composites, polytetrafluoroethylene film usually does not affect the resin matrix; polyethersulfone film, polyethersulfone film has excellent heat resistance and chemical resistance, and is often used in high-temperature packaging and electronic material isolation. When in contact with carbon fiber composites, polyethersulfone film usually does not have adverse effects on the resin matrix.

[0029] A plurality of auxiliary material balls 83 are respectively made of fillers, reinforcing materials, separators, reinforcement materials, mold lubricants, pigments and toners. The auxiliary material balls 83 can be used to assist the molding process and enhance the performance of carbon fiber composite materials, while the molding material 82 and the auxiliary material balls 83 provide materials for carbon fiber cloth composites; fillers can be used to adjust the fluidity, viscosity and density of the resin matrix, and improve the performance of carbon fiber composite materials. Commonly used fillers include micro-bead materials, glass micro-beads, wollastonite, etc.; reinforcing materials, in addition to carbon fiber, can also add other types of reinforcing materials, such as glass fiber and aramid fiber, to improve the specific performance of the product , such as impact resistance and wear resistance; release agents are used to prevent the resin matrix from adhering to the mold surface so that demolding can be carried out smoothly during the molding process. Commonly used release agents include wax and silicone oil; mold lubricants can be used to reduce the friction between the mold and the workpiece, making demolding smoother and extending the service life of the mold; reinforcement materials. In some special applications, it may be necessary to add some reinforcement materials to the carbon fiber composite material, such as metal sheets and polymer sheets, to enhance the structural strength and stability of the product; pigments and toners. If it is necessary to dye the carbon fiber composite material or add a specific color effect, pigments or toners can be added to the resin matrix.

[0030] See also Figure 7The temperature control bottom plate 9 includes a pressure-resistant substrate 91, which is fixedly connected to the inner end of the lower mold groove. A plurality of uniformly distributed constant temperature sheets 92 are fixedly connected in the middle of the pressure-resistant substrate 91. The constant temperature sheets 92 are made of graphite fiber material. Graphite has a highly crystalline structure, which enables it to effectively conduct heat. Therefore, the graphite fiber has good thermal conductivity, so it can effectively absorb and conduct heat. A thermal conductive wire 93 is fixedly connected between the plurality of constant temperature sheets 92. A plurality of uniformly distributed electromagnetic blocks 94 are fixedly connected in the middle of the pressure-resistant substrate 91, and the plurality of electromagnetic blocks 94 The plurality of thermostatic plates 92 are staggeredly distributed, and the heat of the heating plate can be evenly dispersed through the thermostatic plates 92. When the heating plate is heated for molding, the heat of part of the high-temperature thermostatic plate 92 is transferred to the low-temperature thermostatic plate 92 by the heat conductive wire 93, so that the overall temperature of the surface of the temperature-controlled bottom plate 9 is uniform, and the electromagnetic block 94 is electrically attached to the magnet to adsorb the reducing iron powder in the hot melt bag 81, so that the evenly placed plurality of composite material balls 8 are adsorbed on the upper end of the temperature-controlled bottom plate 9 by corresponding plurality of electromagnetic blocks 94, so that the plurality of composite material balls 8 are evenly and stably distributed, thereby improving the molding effect.

[0031] Please continue reading Figure 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 close to the conveyor belt 3, and the auxiliary fan 11 is electrically connected to the infrared sensor 10. When the carbon fiber cloth is dropped through the conveyor belt 3, it falls at an angle. When the infrared sensor 10 senses the falling of the carbon fiber cloth, the auxiliary fan 11 is started to blow out wind to change the inclination of the carbon fiber cloth, so that the carbon fiber cloth can fall horizontally to the upper end of the temperature-controlled bottom plate 9. Here, the auxiliary fan 11 is started temporarily.

[0032] A control display screen 12 is fixedly connected to the front end of the molding machine case 2. The control display screen 12 can be used to control the overall operation and observe the working status of the molding machine.

[0033] Working principle: See also Figure 1-8When the carbon fiber cloth is put in through the conveyor belt 3, it falls at an angle. When the infrared sensor 10 senses the falling of the carbon fiber cloth, the auxiliary fan 11 is started to blow out wind to change the inclination of the carbon fiber cloth, so that the carbon fiber cloth can fall horizontally to the upper end of the temperature-controlled bottom plate 9. Then, the electric control slide rail 13 controls the movement of the adjusting slide rod 14 to move the discharge box 15 to the top of the carbon fiber cloth, and the discharge tube 7 inside it is put in. The composite material balls 8 filled in the cylinder 71 are moved by the rotation of the rotating plate 72, and fall from the through hole 73 below, so as to be evenly put in. Multiple composite material balls 8 fall to the upper end of the carbon fiber cloth. When the composite material balls 8 fall to the upper end of the temperature-controlled bottom plate 9, the electromagnetic block 94 is electrically connected to the magnet to adsorb the reducing iron powder in the hot melt bag 81, so that the multiple composite material balls 8 corresponding to the multiple electromagnetic blocks 94 are adsorbed on the upper end of the temperature-controlled bottom plate 9, so that the multiple composite material balls 8 are adsorbed on the upper end of the temperature-controlled bottom plate 9. The material balls 8 are evenly distributed. After the conveyor belt 3 is used to transport the carbon fiber cloth for the second time to cover the multiple composite material balls 8, the electric control slide rail 13 controls the adjustment slide rod 14 to reset the discharge 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 plate 5 downward for molding. After heating and molding through the heating plate, the polyethylene wax is melted by the hot melt bag 81, and the reducing iron powder is in contact with the air to produce an oxidation-reduction reaction to release a large amount of heat, so that the carbon fiber composite material dissipates heat from the inside to the outside during molding, and when receiving pressure, the multiple auxiliary material balls 83 are evenly dispersed after being compressed. When heating and molding through the heating plate, the heat conducting wire 93 transfers part of the heat of the high-temperature thermostat 92 to the low-temperature thermostat 92, so that the overall temperature of the surface of the temperature control bottom plate 9 is uniform, so that the carbon fiber cloth and the composite material ball 8 are heated evenly as a whole.

[0034] It can be seen from the above technical solutions that the present invention has the following beneficial effects: This solution can achieve the purpose of uniform heating by laying the carbon fiber cloth on the upper end of the temperature-controlled base plate 9 and combining it with multiple composite balls 8 for molding. Multiple electromagnetic blocks 94 are used to respectively adsorb multiple composite balls 8, so that multiple composite balls 8 are evenly laid on the upper end of the temperature-controlled base plate 9, and multiple constant temperature sheets 92 are used to evenly disperse the local excessive temperature, so that the local low temperature can be made uniform by the temperature of other constant temperature sheets 92, so that the temperature of the end surface of the temperature-controlled base plate 9 is made uniform, so that the outer surface of the carbon fiber cloth is heated evenly, and the composite balls 8 can not only provide other materials conducive to synthesis for the carbon fiber composite material, but also provide heat from the inside out, so that the carbon fiber composite material is heated evenly as a whole during the molding process, thereby effectively improving the molding of the carbon fiber composite material.
