This effectively solves the problems of easy deformation and inaccurate positioning of traditional molds under high temperature and high pressure, and improves the molding quality and production efficiency of carbon fiber wheels.

[0043] Example 2 Reference Figure 2 and Figure 3 The difference between this embodiment and the above embodiment is that a temperature control device and a pressure monitoring device are added to further improve the working performance and safety of the mold.

[0044] Specifically, a temperature sensor and a heating element are provided inside the annular mold 3. The temperature sensor is used to monitor the temperature inside the mold in real time, and the heating element is used to adjust the temperature inside the mold. In this way, it is possible to ensure that the mold maintains a constant temperature during the molding process, avoid changes in material properties caused by temperature differences, and improve molding accuracy.

[0045] Furthermore, a pressure sensor is provided on the outer wall of the annular mold 3, and the pressure sensor is used to monitor the pressure in the mold in real time. The pressure sensor is connected to an external control system, and can automatically adjust the pressure output of the pressurizing device according to the actual pressure situation to ensure that the pressure in the mold is always kept within the optimal range.

[0046] The bottom of the annular mold 3 is provided with a cooling channel, which is connected to an external cooling water system. After the molding is completed, the temperature of the mold can be quickly reduced by cooling water, the demoulding speed can be accelerated, and the production efficiency can be improved.

[0048] Safety valves are provided on both sides of the annular mold 3, and the safety valves are used to automatically release pressure in the event of overpressure to ensure the safety of operators.

[0049] The implementation principle of this embodiment is: by introducing a temperature control device and a pressure monitoring device, the comprehensive monitoring and adjustment of the working environment of the mold is realized, ensuring that the mold operates in the best state. At the same time, by setting cooling channels and exhaust holes, the heat dissipation efficiency and exhaust capacity of the mold are improved, and the molding quality and production efficiency are further improved. This not only improves the reliability and safety of the mold, but also provides technical support for subsequent automated production.

[0050] Example 3 Reference Figure 2 and Figure 3 The difference between this embodiment and the above embodiments is that new materials and technologies are used to further improve the durability and environmental protection of the mold.

[0051] Specifically, the main body material of the annular mold 3 is made of high-performance ceramic material, which has extremely high heat resistance and wear resistance and can work stably for a long time under high temperature and high pressure. Compared with traditional metal materials, ceramic materials have better chemical stability and lower thermal expansion coefficient, reducing deformation caused by thermal expansion and contraction.

[0052] The surfaces of the top mold 1 and the bottom mold 2 are coated with a layer of nano coating, which has self-cleaning function and anti-adhesion performance, and can effectively prevent the residue of carbon fiber material on the mold surface, thereby improving the service life and cleaning efficiency of the mold.

[0053] The inside of the annular mold 3 is provided with a multi-layer heat insulation layer, which is made of graphene material and has excellent heat insulation performance. This can effectively reduce heat transfer and energy consumption, and also protect external equipment from high temperature.

[0054] The outside of the annular mold 3 is wrapped with a degradable protective film, which does not release harmful substances during use and can be naturally decomposed after being discarded, meeting environmental protection requirements.

[0055] A plurality of vibrators are arranged inside the annular mold 3, and the vibrators are used to generate small vibrations during the molding process, which are helpful for the uniform distribution of materials and the discharge of bubbles, thereby improving the molding quality.

[0056] Sealing rings are arranged at both ends of the annular mold 3. The sealing rings are made of fluororubber material and have good high temperature resistance and corrosion resistance. They can effectively prevent external impurities from entering the mold and ensure the cleanliness of the molding environment.

[0057] The implementation principle of this embodiment is: by using high-performance ceramic materials and nano-coatings, the durability and anti-pollution ability of the mold are greatly improved. At the same time, by setting up multiple layers of insulation and vibrators, the thermal management and molding quality of the mold are further optimized. This not only prolongs the service life of the mold, but also reduces energy consumption and environmental pollution, and has important economic and social benefits.

[0058] Example 4 Reference Figure 2 and Figure 3 The difference between this embodiment and the above-mentioned embodiment is that the concept of modularization and customizability is adopted to further improve the flexibility and adaptability of the mold.

[0059] Specifically, each enclosure 36 of the annular mold 3 can be independently disassembled and replaced, and the size and shape of each enclosure 36 can be customized according to specific needs. In this way, the structure of the mold can be quickly adjusted for different models and specifications of wheels to meet diverse production needs.

[0060] The top mold 1 and the bottom mold 2 can also be replaced as needed. Different types of top molds 1 and bottom molds 2 can be quickly connected through standard interfaces to achieve fast switching. This can save mold replacement time and improve production efficiency.

[0061] The inside of the ring mold 3 is provided with a plurality of sensor interfaces, which are used to connect various sensors, such as temperature sensors, pressure sensors, humidity sensors, etc. These sensors can be selectively installed according to actual production needs to achieve real-time monitoring and data collection.

[0062] The outside of the ring mold 3 is provided with a plurality of interfaces, which are used to connect various auxiliary devices, such as a heating device, a cooling device, a vacuum pump, etc. These interfaces are standardized and can be easily connected with other devices, thereby improving the integration and flexibility of the system.

[0063] The inside of the annular mold 3 is provided with a plurality of slots for inserting various functional modules, such as a heating plate, a cooling plate, a vibrator, etc. These functional modules can be selectively inserted according to actual production requirements to achieve multifunctional integration.

[0064] The outside of the ring mold 3 is provided with a plurality of indicator lights, which are used to display the working status of the mold, such as temperature, pressure, fault, etc. The operator can timely understand the working status of the mold by observing the status of the indicator lights and take corresponding measures.

[0065] The implementation principle of this embodiment is: by adopting the concept of modularization and customization, the mold has a high degree of flexibility and adaptability. This not only simplifies the maintenance and replacement process of the mold, but also improves production efficiency and product quality. At the same time, by integrating a variety of sensors and auxiliary equipment, comprehensive monitoring and management of the mold work is achieved, further improving the intelligence level of the mold.

[0066] Example 5 Reference Figure 2 and Figure 3 The difference between this embodiment and the above embodiments is that a multi-layer structure and a composite material are used to further improve the comprehensive performance and economic benefits of the mold.

[0067] Specifically, the main body of the annular mold 3 is made of multi-layer composite materials, and the selection and thickness of each layer of material are carefully calculated to achieve the best mechanical and thermal properties. The outermost layer is made of high-strength alloy material with excellent wear resistance and corrosion resistance; the middle layer is made of carbon fiber reinforced plastic with the characteristics of light weight and high strength; the innermost layer is made of high-temperature resistant ceramic material with excellent heat resistance and insulation.

[0068] The top mold 1 and the bottom mold 2 also adopt a similar multi-layer structure, with the outermost layer made of stainless steel, the middle layer made of carbon fiber reinforced plastic, and the innermost layer made of high-temperature resistant ceramic material. This multi-layer structure can give full play to the advantages of each layer of material and improve the overall performance of the mold.

[0069] The annular mold 3 is provided with a plurality of reinforcing ribs, which are made of three-dimensional woven carbon fiber material and have extremely high strength and rigidity. These reinforcing ribs can effectively improve the bearing capacity and impact resistance of the mold and extend the service life of the mold.

[0070] The outside of the annular mold 3 is provided with a plurality of heat sinks, which are made of aluminum alloy and have good thermal conductivity. These heat sinks can effectively dissipate the heat inside the mold, reduce the temperature of the mold, and improve the cooling efficiency of the mold.

[0071] A plurality of sound-absorbing cottons are arranged inside the annular mold 3, and the sound-absorbing cottons are used to absorb the noise generated during the molding process and reduce noise pollution. This can improve the working environment and increase the comfort and work efficiency of the workers.

[0072] A plurality of lubricant nozzles are arranged inside the annular mold 3, and the lubricant nozzles are used to spray lubricants during the molding process to reduce friction and improve molding efficiency. These nozzles can spray lubricants regularly and quantitatively to ensure that the mold surface is always in a good lubricated state.

[0073] The implementation principle of this embodiment is: by adopting a multi-layer structure and composite materials, the advantages of each layer of material are fully utilized to improve the comprehensive performance of the mold. At the same time, by setting multiple functional structures such as reinforcing ribs, heat sinks, sound-absorbing cotton and lubricant nozzles, the working conditions and production efficiency of the mold are further optimized. This not only improves the durability and reliability of the mold, but also reduces energy consumption and noise pollution, which has important economic and environmental significance.
