Description

Technical Field

[0001] This invention relates to the field of armor sheet technology, specifically to an impact-resistant armor sheet and its preparation process and molding equipment. Background Technology

[0002] Existing non-metallic protective armor plates suffer from numerous technical shortcomings, primarily in their limited protective functions, insufficient intelligence, and constraints on manufacturing processes. Traditional armor plates can only provide basic ballistic and blast resistance, failing to meet the demands of the complex environments of modern battlefields, particularly lacking any defensive capability against electronic reconnaissance methods such as radar signal detection. Functionally, existing products lack real-time feedback mechanisms, unable to provide signal feedback alarms or precise location tracking upon being attacked. Furthermore, traditional armor materials often struggle to simultaneously achieve multiple protective properties such as stealth shielding, fire resistance, and thermal insulation, and also exhibit significant deficiencies in wear resistance, impact resistance, and lightweight structure.

[0003] In terms of manufacturing processes, existing molding equipment struggles to meet the stringent temperature control requirements of novel composite armor materials. Conventional pressing equipment suffers from slow heating and cooling rates and poor temperature uniformity, severely impacting interlayer bonding strength and material performance stability. Particularly when processing composite armor materials containing embedded electronic layers, traditional equipment cannot achieve rapid and precise temperature control, resulting in low product yield and unstable performance.

[0004] Therefore, there is a need for an impact-resistant armor sheet and its manufacturing process and molding equipment to overcome the above problems. Summary of the Invention

[0006] This application provides an impact-resistant armor sheet, the technical solution of which includes an embedded electronic layer for sensing impact, a mechanical protection layer disposed outside the embedded electronic layer for improving the impact resistance of the sheet, and a heat insulation layer disposed outside the embedded electronic layer for improving the heat insulation of the sheet.

[0007] Furthermore, this application also proposes that the embedded electronic layer is a chip circuit network, which is disposed in the middle part of the sheet; multiple mechanical protection layers and multiple heat insulation layers are symmetrically and spaced apart on both sides of the chip circuit network; the mechanical protection layer is a carbon fiber cloth layer and / or an aramid fiber layer and / or an ultra-high molecular weight polyethylene layer and / or a PBO layer; the heat insulation layer is a silicon carbide fiber layer and / or an aerogel plate layer and / or a polyimide layer.

[0008] Furthermore, this application also proposes the following steps: S1, weaving raw materials; cutting ultra-high molecular weight polyethylene, aramid fiber, carbon fiber, polyimide, and PBO into strips 100mm wide, and then weaving them separately according to a warp and weft interlacing pattern to form square sheets of 1.2m and 1.2m respectively; S2, cutting and preparing materials; cutting 5mm aerogel board, silicon carbide fiber cloth, and chip circuit network into square sheets of 1.2m and 1.2m; S3, stacking materials; stacking the prepared square sheets in a specific order; using resin adhesive or resin film as a medium to bond the sheets together; S4, cold and hot cycle pressing molding; using molding equipment to perform cold and hot pressing cycle treatment on the stacked raw materials; S5, vacuum hot pressing molding; placing the sheets in a hot press tank for vacuum hot pressing treatment; S6, surface treatment; cleaning the edges of the sheets and then spraying a special polyurea coating.

[0009] Furthermore, this application also proposes a frame that provides installation space for the entire device, a lower pressure plate mounted on the frame for supporting the sheet material, an upper pressure plate mounted on the frame via a hydraulic mechanism to support the sheet material in conjunction with the lower pressure plate, and a temperature regulating component mounted on the lower and upper pressure plates for regulating the temperature of the lower and upper pressure plates; the temperature regulating component is configured with a heating component and a cooling component, and the temperature regulating component regulates the temperature of the lower and upper pressure plates by switching the positions of the heating component and the cooling component.

[0010] Furthermore, this application also proposes that the temperature regulating component includes a storage compartment disposed on both sides of the lower pressure plate and the upper pressure plate, a heating component disposed inside one of the storage compartments, which is disposed inside the lower pressure plate and the upper pressure plate when unfolded, and disposed inside the storage compartment when folded, and a cooling component disposed inside the other storage compartment, which is disposed inside the lower pressure plate and the upper pressure plate when unfolded, and disposed inside the storage compartment when folded; wherein when one of the heating component and the cooling component is located inside the storage compartment, the other is located inside the lower pressure plate and the upper pressure plate.

[0011] Furthermore, this application also proposes that the heating component includes multiple temperature control units that are slidably disposed inside the storage compartment, and a telescopic component disposed on the multiple temperature control units for controlling the expansion and contraction of the multiple temperature control units; the heating component and the cooling component have the same structure.

[0012] Furthermore, this application also proposes that the temperature control unit includes a temperature control plate slidably disposed inside the storage compartment, sliders disposed at both ends of the temperature control plate, one slider having a closed channel inside and the other slider having an open channel inside, a connecting pipe connected to the open channel of the slider, and a circulation channel, which are formed by the combination of the channel inside the temperature control plate, the closed channel inside the slider, the open channel inside the slider, and the connecting pipe.

[0013] Furthermore, this application also proposes that the telescopic component includes a groove inside the slider, a through groove inside the slider and communicating with the groove, a tension spring inside the groove for connecting two adjacent sliders, and an airbag inside the through groove and located inside the tension spring, wherein the airbag can separate multiple sliders after being inflated.

[0014] Furthermore, this application also proposes that the air bladder of the heating component and the air bladder of the cooling component are connected by a pipe, and the pipe is equipped with an air pump and a solenoid valve.

[0015] Furthermore, this application also proposes that the storage compartment is made of thermal insulation material, and the upper and lower pressure plates are made of thermally conductive material.

[0016] The beneficial effects of the embodiments of the present invention are as follows:

[0017] This application achieves impact sensing functionality through an embedded electronic layer, which, in conjunction with an external mechanical protective layer and a heat insulation layer, enhances intelligent sensing capabilities while maintaining the protective performance of traditional armor. The mechanical protective layer disperses impact energy using high-strength fiber materials, the heat insulation layer blocks heat transfer using low thermal conductivity materials, and the embedded electronic layer monitors impact events in real time.

[0018] This application achieves accurate sensing and efficient protection of impact signals by placing the chip circuit network at the center of the sheet and symmetrically arranging protective structures on both sides. The chip circuit network can monitor the impact force on the sheet in real time and provide feedback on the impact information through electrical signals. The symmetrically arranged mechanical protective layers can evenly disperse impact energy, and the multi-layer structure design improves the overall impact resistance. The multi-layered arrangement of the heat insulation layer effectively blocks heat transfer and protects the internal electronic components.

[0019] This application employs telescopic components to separately control the folding and unfolding actions of the heating and cooling components within the pressure plate and storage chamber: when the system needs to heat up, the cooling components are folded to eliminate their interference with the heating process, thereby improving the heating rate and effect; conversely, during cooling conditions, the heating components are folded to avoid affecting the cooling efficiency. This alternating unfolding working mode effectively solves the problem of mutual interference between hot and cold media in traditional systems, significantly improving the response speed of temperature regulation.

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] This application proposes an impact-resistant armor sheet comprising an embedded electronic layer, a mechanical protective layer, and a thermal insulation layer. The embedded electronic layer is used to sense impacts, the mechanical protective layer is disposed outside the embedded electronic layer to enhance impact resistance, and the thermal insulation layer is disposed outside the embedded electronic layer to enhance thermal insulation.

[0033] The embedded electronic layer can employ a piezoelectric sensor array or strain sensor network to achieve impact sensing, and its thickness can be controlled within the range of 0.1-1 mm. The mechanical protective layer can be made of unidirectional fiber-reinforced composite material or a three-dimensional braided structure, with a preferred thickness of 2-10 mm. The thermal insulation layer can be made of porous ceramic material or phase change material, with a preferred thickness of 3-8 mm. The layers can be bonded together using epoxy resin or polyurethane adhesive, with the adhesive layer thickness controlled within 0.05-0.2 mm.

[0034] This application achieves impact sensing functionality through an embedded electronic layer, combined with external mechanical and thermal insulation layers, adding intelligent sensing capabilities while maintaining the protective performance of traditional armor. The mechanical protective layer disperses impact energy using high-strength fiber materials, the thermal insulation layer blocks heat transfer using low thermal conductivity materials, and the embedded electronic layer monitors impact events in real time. Compared with existing technologies, this solution integrates protective performance and sensing functions while maintaining lightweight characteristics, solving the problem that traditional armor cannot provide real-time feedback on damage. The synergistic effect of each functional layer enables the armor plates to effectively protect against impacts and promptly issue early warning signals.

[0035] Furthermore, this application also proposes that the embedded electronic layer is a chip circuit network, which is disposed in the middle part of the sheet; multiple mechanical protection layers and multiple heat insulation layers are symmetrically and spaced on both sides of the chip circuit network; the mechanical protection layer is a carbon fiber cloth layer and / or an aramid fiber layer and / or an ultra-high molecular weight polyethylene layer and / or a PBO layer; the heat insulation layer is a silicon carbide fiber layer and / or an aerogel plate layer and / or a polyimide layer.

[0036] Specifically, the chip circuit network is composed of integrated circuit elements, electrically connected to form a mesh structure capable of sensing impacts and generating electrical signals. The chip circuit network can be implemented using flexible circuit board technology, where circuit patterns are formed on a flexible substrate through etching or printing. Symmetrical arrangements of multi-layer mechanical protective layers include, but are not limited to: alternating layers of carbon fiber cloth and aramid fiber, or alternating layers of ultra-high molecular weight polyethylene and PBO. Multi-layer arrangements of the thermal insulation layer include: a combination of silicon carbide fiber layers and aerogel sheet layers, or the use of polyimide layers alone. The layers are bonded together with resin adhesives, preferably epoxy resins or polyurethane adhesives.

[0037] This application achieves accurate sensing and efficient protection against impact signals by placing a chip circuit network at the center of the sheet and symmetrically arranging protective structures on both sides. The chip circuit network can monitor the impact force on the sheet in real time and provide impact information feedback through electrical signals. The symmetrically arranged mechanical protective layers can evenly disperse impact energy, and the multi-layer structure design improves the overall impact resistance. The multi-layered arrangement of the heat insulation layer effectively blocks heat transfer and protects the internal electronic components. Compared with a single-layer protective structure, this solution has better impact resistance and signal feedback reliability while maintaining a lighter overall weight. By combining different materials, the protective performance and cost can be adjusted according to actual needs.

[0038] This application also proposes a manufacturing process for impact-resistant armor sheets, including the following steps:

[0039] In the raw material weaving stage, ultra-high molecular weight polyethylene, aramid fiber, carbon fiber, polyimide, and PBO are cut into 100mm wide strips and woven into 1.2*1.2m square sheets using an interlaced warp and weft pattern. In the cutting and preparation stage, 5mm aerogel boards, silicon carbide fiber cloth, and chip circuit networks are cut into square sheets of the same size. In the stacking stage, sheets of various materials are stacked in a specific order, with resin adhesives or resin films used to bond the layers together. In the hot and cold cycling pressing stage, the sheets are first cold-pressed at 18-20 MPa for 3-5 minutes, then heated to 140-150℃ within 3-10 minutes and hot-pressed at 25 MPa for 30-40 minutes, followed by cooling to 30℃ and cold-pressing again, repeated 3 times. In the vacuum hot pressing stage, the sheets are placed in a -1 MPa vacuum environment, heated to 160℃, and then pressurized to 1.2 MPa for 50-60 minutes. In the surface treatment stage, after cleaning the edges, heat to 60-70℃ and then spray a special polyurea coating, and let it dry in an environment of 20-30℃ for 24 hours.

[0040] Specifically, the weave pattern can employ plain weave, twill weave, or satin weave, with plain weave being preferred to ensure isotropic mechanical properties. The resin adhesive can be epoxy resin, polyurethane, or acrylate, with modified epoxy resin exhibiting good toughness being preferred. During the hot and cold cycling pressing process, controlling the heating rate at 0.5-3℃ / min effectively avoids interlayer stress concentration. In the vacuum hot pressing stage, the holding time is directly proportional to the material thickness; for every 1mm increase in thickness, the holding time needs to be extended by 5-8 minutes. The thickness of the special polyurea coating should be controlled between 0.2-0.5mm; excessive thickness will affect the overall flexibility of the armor.

[0041] Therefore, this manufacturing process solves the technical problems of insufficient interlayer bonding strength and uneven thermal stress distribution in traditional armor sheets by precisely controlling the lamination sequence and pressing parameters of the multilayer composite material. The alternating hot and cold pressing process effectively eliminates residual stress, vacuum hot pressing ensures complete interlayer compaction, and special coating treatment enhances surface protection performance. Compared with conventional single-pass hot pressing, this process improves interlayer shear strength. The optimized matching of parameters for each process ensures both product performance and process stability and repeatability.

[0042] See Figure 1-7 This application also proposes a molding apparatus for preparing impact-resistant armor sheets. The apparatus includes a frame 1, a lower pressure plate 2, an upper pressure plate 3, and a temperature regulating component 4. The frame 1 provides installation space for the entire apparatus. The lower pressure plate 2 is mounted on the frame 1 to support the sheet. The upper pressure plate 3 is mounted on the frame 1 via a hydraulic mechanism and cooperates with the lower pressure plate 2 to press the sheet. The temperature regulating component 4 is mounted on the lower pressure plate 2 and the upper pressure plate 3 to regulate their temperatures. The temperature regulating component 4 is equipped with a heating component and a cooling component; temperature regulation is achieved by switching the positions of these two components.

[0043] Specifically, the temperature regulating component 4 includes storage compartments 41 disposed on both sides of the lower pressure plate 2 and the upper pressure plate 3. Heating and cooling components are respectively disposed inside the two storage compartments 41. The heating component is disposed inside the lower pressure plate 2 and the upper pressure plate 3 when unfolded, and inside the storage compartment 41 when folded; the cooling component operates in the same manner. When the cooling component is inside the storage compartment 41, the heating component is located inside the lower pressure plate 2 and the upper pressure plate 3. The heating component includes multiple temperature control units 42 slidably disposed inside the storage compartment 41, and telescopic components 43 disposed on the temperature control units 42 for controlling their unfolding and folding. The cooling component has the same structure as the heating component. The temperature control unit 42 includes a temperature control plate 421, sliders 422 disposed at both ends of the temperature control plate 421, a connecting pipe 423, and a circulation channel 424 formed by the combination of these components. The sliders 422 have either a closed channel or an open channel inside, and the connecting pipe 423 connects to the open channel. The telescopic assembly 43 includes a groove 431 and a through groove 432 formed inside the slider 422. A tension spring 433 disposed inside the groove 431 is used to connect adjacent sliders 422, and an air bladder 434 disposed inside the through groove 432. When the air bladder 434 is inflated, it can separate multiple sliders 422. The air bladders 434 of the heating and cooling assemblies are connected by a pipe with an air pump and a solenoid valve. The storage compartment 41 is made of thermal insulation material, while the upper pressure plate 3 and the lower pressure plate 2 are made of thermally conductive material.

[0044] Therefore, this molding equipment, through the design of the temperature regulation component 4, achieves the requirement for rapid heating and cooling during sheet pressing. The heating and cooling components can work alternately, with the expansion and contraction of the temperature control unit 42 controlled by the inflation and deflation of the air bladder 434, thus quickly switching temperature regulation modes. The circulation channel 424 in the temperature control unit 42 ensures efficient heat transfer, while the insulation performance of the storage chamber 41 ensures the stability of temperature regulation. This equipment solves the problems of slow temperature regulation and low efficiency in traditional molding equipment when pressing multi-layer composite armor sheets, and can better meet the manufacturing process requirements of armor sheets with special performance requirements.

[0045] This application also proposes that the temperature regulating component 4 includes a storage compartment 41, a heating component, and a cooling component. The storage compartment 41 is disposed on both sides of the lower pressure plate 2 and the upper pressure plate 3. The heating component is disposed inside one of the storage compartments 41, positioned inside the lower pressure plate 2 and the upper pressure plate 3 when unfolded, and positioned inside the storage compartment 41 when folded. The cooling component is disposed inside the other storage compartment 41, positioned inside the lower pressure plate 2 and the upper pressure plate 3 when unfolded, and positioned inside the storage compartment 41 when folded. When one of the heating component and the cooling component is located inside the storage compartment 41, the other is located inside the lower pressure plate 2 and the upper pressure plate 3.

[0046] The storage chamber 41 can adopt a double-layer stainless steel shell structure, with the interlayer filled with aerogel insulation material to achieve a heat preservation effect. The heating component can use an array of heating wires or a carbon nanotube heating film as a heat source, and heat transfer is achieved through the heating medium inside the circulation channel 424. The cooling component can use a semiconductor cooling chip or a micro compressor cooling system, and rapid cooling is achieved through the cooling medium inside the circulation channel 424. A guide rail mechanism can be set inside the storage chamber 41 to facilitate the sliding deployment and folding of the temperature control unit 42. The switching between the heating and cooling components can be achieved through a pneumatic control system, in which the airbag 434 is inflated and pushes the slider 422 to separate, allowing the temperature control unit 42 to move along the guide rail to the working position.

[0047] This application achieves rapid temperature regulation of the pressure plate by integrating heating and cooling components within a switchable storage chamber 41. When heating is required, the heating component extends into the pressure plate, while the cooling component retracts into the storage chamber 41; the reverse is true when cooling is required. This design solves the problems of slow heating and cooling speeds and high energy consumption in traditional equipment, avoiding energy loss during temperature regulation through physical isolation. Compared with existing technologies, this solution has advantages such as fast response speed, high temperature control accuracy, and high energy utilization, and can meet the stringent requirements of rapid temperature field changes in special composite material molding processes.

[0048] Furthermore, this application also proposes that the heating assembly includes a temperature control unit 42 and a telescopic assembly 43. Multiple temperature control units 42 are provided and slidably disposed inside the storage compartment 41. The telescopic assembly 43 is disposed on the multiple temperature control units 42 and is used to control the expansion and contraction of the multiple temperature control units 42. The heating assembly and the cooling assembly have the same structure.

[0049] The temperature control unit 42 includes a temperature control plate 421, a slider 422, a connecting pipe 423, and a circulation channel 424. The temperature control plate 421 is slidably disposed inside the storage compartment 41. The sliders 422 are disposed at both ends of the temperature control plate 421, with one slider 422 having a closed channel inside and the other slider 422 having an open channel inside. The connecting pipe 423 is connected to the open channel of the slider 422. The circulation channel 424 is formed by the combination of the channel inside the temperature control plate 421, the closed channel inside the slider 422, the open channel inside the slider 422, and the connecting pipe 423. The telescopic assembly 43 includes a groove 431, a through groove 432, a tension spring 433, and an airbag 434. The groove 431 is formed inside the slider 422. The through groove 432 is formed inside the slider 422 and communicates with the groove 431. The tension spring 433 is disposed inside the groove 431 and is used to connect two adjacent sliders 422. The airbag 434 is located inside the through groove 432 and inside the tension spring 433. After the airbag 434 is inflated, it can separate multiple sliders 422. The airbag 434 of the heating component and the airbag 434 of the cooling component are connected by a pipe, and an air pump and a solenoid valve are installed on the pipe.

[0050] In a specific embodiment: the temperature control unit 42 forms a circulation channel 424 through the cooperation of the slider 422 and the connecting pipe 423, allowing the heat transfer medium to flow within the circulation channel 424, thereby achieving rapid temperature regulation. The telescopic component 43, through the cooperation of the tension spring 433 and the airbag 434, can control the expansion and contraction of the temperature control unit 42, enabling the heating and cooling components to quickly switch positions as needed. Specifically, when the airbag 434 inflates, it pushes the slider 422 to separate, causing the temperature control unit 42 to expand; when the airbag 434 deflates, the tension spring 433 pulls the slider 422 back, causing the temperature control unit 42 to contract.

[0051] In this application, the heating and cooling components can efficiently regulate the temperature, meeting the need for rapid heating and cooling of the sheet material during pressing and molding. As a preferred embodiment, the circulation channel 424 can be filled with heat-conducting oil as a heat transfer medium to further improve heat transfer efficiency.

[0052] This application also proposes a specific structure for the temperature control unit 42. The temperature control unit 42 includes a temperature control plate 421, a slider 422, a connecting pipe 423, and a circulation channel 424. The temperature control plate 421 is slidably disposed inside the storage compartment 41. The sliders 422 are disposed at both ends of the temperature control plate 421, with one slider 422 having a closed channel and the other slider 422 having an open channel. The connecting pipe 423 is connected to the open channel of the slider 422. The circulation channel 424 is formed by the combination of the channel inside the temperature control plate 421, the closed channel inside the slider 422, the open channel inside the slider 422, and the connecting pipe 423.

[0053] As a specific embodiment: the temperature control plate 421 can be made of thermally conductive materials such as aluminum alloy or copper alloy, with a thickness of 5-10mm. The slider 422 can be made of engineering plastic or metal, with an internal channel diameter of 3-5mm. The connecting pipe 423 is made of flexible metal corrugated pipe or silicone tube, which facilitates maintaining connection during expansion and contraction. The circulation channel 424 can circulate heat transfer oil or coolant, and heat exchange is achieved through external pumping.

[0054] As a preferred embodiment, the connecting pipe 423 can be a quick connector for easy maintenance and replacement. The cross-sectional shape of the circulation channel 424 can be circular or rectangular, optimized according to space requirements.

[0055] This application achieves efficient heat exchange in the temperature regulation component 4 through a modular temperature control unit 42 design. The combined structure of the temperature control plate 421 and the slider 422 ensures both thermal conductivity and ease of storage and deployment. The optimized design of the circulation channel 424 improves heat exchange efficiency and enables rapid response to temperature regulation needs. Compared with existing technologies, this solution has advantages such as compact structure, high heat exchange efficiency, and convenient maintenance, effectively solving the technical challenge of rapid temperature rise and fall during the pressing process of molding equipment.

[0056] This application also proposes that the telescopic assembly 43 includes a groove 431, a through groove 432, a tension spring 433, and an airbag 434. The groove 431 is formed inside the slider 422, the through groove 432 is formed inside the slider 422 and communicates with the groove 431, the tension spring 433 is disposed inside the groove 431 for connecting two adjacent sliders 422, and the airbag 434 is disposed inside the through groove 432 and located inside the tension spring 433. After the airbag 434 is inflated, it can separate multiple sliders 422.

[0057] In a specific embodiment: the groove 431 is a receiving space opened inside the slider 422 for installing the tension spring 433 and restricting its movement trajectory. The through groove 432 communicates with the groove 431 to form the installation space for the airbag 434. The tension spring 433 is made of an elastic metal material and remains in a contracted state in its natural state, allowing adjacent sliders 422 to be tightly connected. The airbag 434 is made of a flexible, high-temperature resistant material and generates radial thrust through inflation, pushing the sliders 422 to slide apart. As a preferred embodiment, the airbag 434 can be made of silicone rubber or fluororubber, with an operating temperature range covering -50°C to 200°C.

[0058] This application controls the separation and resetting of the slider 422 by inflating and deflating the airbag 434, thereby enabling the rapid deployment and folding of the temperature control unit 42. When it is necessary to switch the temperature mode, inflating the corresponding airbag 434 causes the slider 422 group to separate and move the temperature control plate 421, thus changing the working state of the temperature regulation component 4. Compared with the traditional mechanical transmission structure, this design has advantages such as fast response speed, high action accuracy, and good high temperature resistance, and can meet the stringent requirements for temperature regulation speed in the sheet pressing process.

[0059] Traditional hot and cold circulation systems employ a single circulating pipe design. During cooling, the original heating medium within the pipe must first be replaced by a cooling medium. This means the cooling medium must not only absorb heat from the pressure plate and sheets but also remove heat accumulated within the circulating pipe itself, resulting in prolonged cooling time. Similarly, similar inefficiencies exist during heating, making rapid temperature control difficult in single-circulation pipe systems. To address this technical deficiency, this application employs a telescopic component 43 to separately control the folding and unfolding actions of the heating and cooling components within the pressure plate and storage chamber 41: when the system needs to heat up, the cooling component is folded to eliminate its interference with the heating process, thereby improving the heating rate and effect; conversely, during cooling, the heating component is folded to avoid its impact on cooling efficiency. This alternating unfolding working mode effectively solves the problem of mutual interference between hot and cold media in traditional systems, significantly improving the response speed of temperature regulation.

[0060] This application also proposes that the air bladder 434 of the heating component and the air bladder 434 of the cooling component are connected by a pipe, and an air pump and a solenoid valve are installed on the pipe.

[0061] In a specific embodiment, the airbag 434, through a pipe connection design, enables the heating and cooling components to be controlled in tandem. An air pump provides gas pressure, and a solenoid valve controls the gas flow direction. In a preferred embodiment, the airbag 434 can be made of high-temperature resistant silicone material, the pipes can be stainless steel bellows, the air pump can be a miniature diaphragm pump, and the solenoid valve can be a two-position three-way solenoid valve. Thus, by switching the solenoid valve, the inflation and deflation of the airbag 434 can be controlled, thereby enabling the deployment and retraction of the temperature control unit 42.

[0062] This application achieves rapid switching between heating and cooling modes through a pneumatic linkage mechanism. The linkage design of the airbag 434 avoids timing errors caused by individual control; that is, when the airbag 434 in the heating component is inflated, the airbag 434 in the cooling component must be in an deflated state; that is, when the heating component unfolds, the cooling component must retract, and vice versa. This ensures the response speed of the heating and cooling components' unfolding or retracting. Precise control through a solenoid valve guarantees the reliability of the switching process. Compared with existing technologies, this solution features fast response speed, high control precision, and good system stability, effectively solving the problem of untimely temperature regulation during hot and cold pressing molding.

[0063] This application also proposes that the storage compartment 41 is made of thermal insulation material, and the upper pressure plate 3 and the lower pressure plate 2 are made of thermally conductive material.

[0064] As a specific embodiment: the insulation material can be a low thermal conductivity material such as polyurethane foam, rock wool, or vacuum insulation board, and its thermal conductivity needs to be controlled below 0.05 W / (m·K). The thermally conductive material is preferably aluminum alloy or copper alloy, and its thermal conductivity needs to be greater than 150 W / (m·K). As a preferred embodiment, a silicone sealing strip is provided on the contact surface between the insulation material and the thermally conductive material to prevent heat exchange. The insulation layer thickness of the storage compartment 41 is designed to be 30-50 mm, and the thickness of the upper pressure plate 3 and the lower pressure plate 2 is designed to be 20-30 mm. The thermally conductive material is embedded with uniformly heated graphite sheets to improve heat conduction efficiency.

[0065] This application solves the technical problem of energy loss during alternating heating and cooling processes by combining thermal insulation and thermally conductive materials. When the heating component is working, the thermally conductive material quickly conducts heat to the plate, while the thermal insulation material effectively prevents heat from diffusing into the storage chamber 41 and also prevents cold energy from diffusing into the upper pressure plate 3 and lower pressure plate 2. When switching to the cooling component, the thermally conductive material quickly dissipates residual heat, while the thermal insulation material prevents external heat from interfering with the cooling process. Compared to traditional single-metal pressure plates, this application can improve temperature regulation efficiency while reducing energy consumption.
