Angle, and the position of the limiting column 3 is consistent with the position of the limiting groove 13, the diameter of the limiting column 3 is slightly smaller than the diameter of the limiting groove 13, and the limiting column 3 is installed in the limiting groove 13, the four mounting columns 4 are evenly set at each corner of the top surface of the pressure plate 5, and the four mounting columns 4 are vertical to the limiting columns 3, the mounting columns 4 on the top surface of the pressure plate 5 pass through the top plate 15, and the bottom surface of the top plate 15 is provided with a slot hole 10, and the position of the slot hole 10 is consistent with the position of the tool holder 14.

[0026] A bottom plate 2 is provided inside the machine body 1, and the bottom plate 2 is installed on the top surface of the pressure plate 5 inside the machine body 1. A tool holder 14 is welded in the middle of the top surface of the bottom plate 2. The tool holder 14 is rectangular as a whole, and the middle of the rectangular tool holder 14 is divided into six smaller rectangular tool holders 14 with the same area. Six sleeves 6 and guide holes 7 are evenly set in the middle of the six smaller rectangular tool holders 14 and set on the top surface of the bottom plate 2, and the pressure plate 5 is installed in the limiting groove 13 on the top surface of the bottom plate 2 through the limiting column 3 on the bottom surface.

At this time, the pressing plate 5 and the mounting frame 8 are at the same level, and then the pre-oxidized silk aerogel felt is installed on the mounting frame 8. After installation, the second sealing film is installed on the mounting column 4 and covers the top surfaces of the six pre-oxidized silk aerogel felts, so that the two sealing films clamp the pre-oxidized silk aerogel felt, and then the top plate 15 is installed on the mounting column 4, so that the top plate 15 presses the top sealing film. At this time, the entire mold can be placed in the working room inside the body 1, and the vacuum hot press is turned on through the control panel.

[0027] When the vacuum hot press is turned on, the vacuum hot press first extracts the air in the studio through the exhaust system to create a lower pressure environment. The purpose of this is to remove gas and moisture, reduce material oxidation and contamination, and provide better heat transfer effects. The vacuum hot press provides constant temperature control through the heating system. The heating source is usually a heating resistor wire or a heating plate, which can transfer the temperature to the material through electric current or resistance heating. While heating, the vacuum hot press applies pressure through a hydraulic system or mechanical device. The size and application method of the pressure depend on the needs of the processed material. It can be applied statically or dynamically. Under the set temperature and pressure conditions, the material is processed and hot-pressed in a vacuum environment, which may include sintering, heat treatment , pressing, molding or other processing operations, depending on the material and process requirements. After processing, the vacuum hot press can be cooled by a cooling system or other means, and then the equipment can be opened to remove the processed material from the fixture or mold. When the vacuum hot press completes heating by pressing down, it continues to heat downward to press the pressing plate 5 and the mounting frame 8 downward. Since the tool holder 14 is fixed, the tool holder 14 will extend upward from the gap between the pressing plate 5 and the six mounting frames 8, so that the tool holder 14 cuts the entire sealing film into separate pre-oxidized silk aerogel felts to complete the segmentation. During the cutting process, since the bottom surface of the top plate 15 is provided with a slot 10, the slot 10 on the bottom surface of the top plate 15 will prevent the tool holder 14 from damaging the top plate 15 during the cutting process. Specific embodiment 2:

[0029] Reference Figure 1-6 , a pre-oxidized silk aerogel felt preparation device, further based on the basic structure in the specific embodiment one, the tool holder 14 can be welded and replaced to be detachable, and four fixing frames are arranged around the outside of the tool holder 14, and the fixing frames are set on the four sides of the tool holder 14, and the fixing frames are set at the bottom end of the tool holder 14, so that when the tool holder 14 is installed, the fixing bolts can be passed through the fixing frames and screwed into the bottom plate 2 to complete the fixing of the tool holder 14, so that when the tool holder 14 is damaged, the fixing bolts can be removed and the damaged tool holder 14 can be replaced, so that when the tool holder 14 is damaged, there is no need to replace the entire bottom plate 2.

[0030] In summary:

[0031] 1. A knife holder 14 is welded on the top surface of the bottom plate 2, and the pressing plate 5 is installed in the limiting groove 13 on the top surface of the bottom plate 2 through the limiting column 3 on the bottom surface. Six mounting frames 8 are arranged in the middle of the knife holder 14. The guide column 11 and the pressing block 9 on the bottom surface of the mounting frame 8 are both installed in the sleeve 6 and the guide hole 7 on the top surface of the bottom plate 2. A reset spring 12 is arranged inside the sleeve 6 and the limiting groove 13. In this way, when in use, the first film can be installed on the mounting column 4 on the top surface of the pressing plate 5, so that the sealing film covers all the mounting frames 8 on the column, and then the pre-oxidized silk aerogel felt is installed on the mounting frame 8. After installation, the second sealing film is installed on the mounting column 4 and covers it. The top surfaces of the six pre-oxidized silk aerogel felts are clamped with two sealing films, and then the top plate 15 is installed on the mounting column 4, so that the top plate 15 presses the top sealing film. At this time, the vacuum hot press continues to heat downward when the downward pressing is completed, so that the pressing plate 5 and the mounting frame 8 are pressed downward. Since the knife holder 14 is fixed, the knife holder 14 will extend upward from the gap between the pressing plate 5 and the six mounting frames 8, so that the knife holder 14 cuts the entire sealing film into individual pre-oxidized silk aerogel felts to complete the segmentation, which solves the problem that multiple pre-oxidized silk aerogel felts that have been sealed cannot be cut into individual pieces of pre-oxidized silk aerogel felt.
