Description

Technical Field

[0001] This utility model relates to the field of alumina fiber technology, specifically to an alumina fiber vacuum forming device. Background Technology

[0002] Alumina fiber is an inorganic ceramic fiber made primarily of alumina (Al2O3) through a specific process. It possesses excellent high-temperature resistance (long-term operating temperature can reach 1400-1600°C or even higher), high melting point, low thermal conductivity, good chemical stability, and thermal shock resistance, while also combining the corrosion resistance of ceramic materials with the flexibility of fiber materials. This high-performance fiber is a key basic material for preparing high-temperature insulation materials, advanced ceramic matrix composites (CMCs), and metal matrix composite (MMC) reinforcements, and is widely used in aerospace, industrial kilns, high-temperature filtration, and other fields. Alumina fiber vacuum forming equipment is a specialized device that uses vacuum negative pressure to adsorb, stack, and shape dispersed alumina fibers (or their slurry) within a specially designed mold, thereby manufacturing alumina fiber preforms or insulation products with complex shapes, low density, and high porosity. It is a key process equipment for preparing high-performance alumina fiber insulation components and composite reinforcements.

[0003] During long-term use, the mold inside the alumina fiber vacuum forming device may experience filter blockage and wear on the sealing surface, requiring the user to disassemble the entire machine for maintenance, which is quite troublesome. In addition, residual fibers and slurry may appear during use, posing a risk of cross-contamination and affecting the production of alumina fibers. To address this, we propose an alumina fiber vacuum forming device. Utility Model Content

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A vacuum forming device for alumina fibers includes: a control console 1, with a connecting door 2 fixedly connected to the surface of the control console 1; characterized in that: a vacuum chamber 4 is fixedly connected to the top of the control console 1; a vacuum pump 5 is installed on the top of the vacuum chamber 4; a vacuum pipeline 6 is installed on one side of the vacuum pump 5; a pressure gauge 7 is fixedly connected to the surface of the vacuum pipeline 6; sealing doors 8 are rotatably connected to both sides of the surface of the vacuum chamber 4; a forming component 9 is slidably connected to the bottom of the inner wall of the vacuum chamber 4; demolding components 10 are fixedly connected to both sides of the inner wall of the vacuum chamber 4; the position of the demolding components 10 matches that of the forming components 9; and multiple heat dissipation holes 3 are provided on the surface of the connecting door 2.

[0028] In this embodiment, the control console 1 can use its internal precision instruments to operate the entire device, while its directional structure supports and maintains the top structure such as the vacuum chamber 4, thereby further improving the stability and safety of the device. The connecting door 2 allows the user to close the control console 1 after operation, and the protection of the connecting door 2 ensures the safety of the instruments inside the control console 1, thereby further improving the safety of the device. The heat dissipation hole 3 can dissipate heat and ventilate the instruments inside the control console 1, thereby further improving the functionality of the device. The vacuum chamber 4 and the vacuum pump 5 work together to extract air from the vacuum pump 5 and release it into the vacuum pipeline 6. This process ensures the vacuum inside the vacuum chamber 4, which facilitates the molding of alumina fibers. The pressure gauge 7 can monitor the pressure at any time, making it convenient for the user to operate. The user can pour the alumina raw material into the molding component 9, and then close the sealing door 8 and turn on the vacuum pump 5 to complete the vacuum molding. The molding component 9 can be disassembled and cleaned by the user at any time during long-term use, and the demolding component 10 can use its structure to keep the internal movement of the molding component 9 to help with demolding, thereby further improving the functionality of the device.

[0029] The molding component 9 includes a mold base 901, a molding mold 902, a placement groove 903, a filter plate 904, an auxiliary handle 905, a pick-up handle 906, and a disassembly slider 907. The mold base 901 is located at the bottom of the inner wall of the vacuum chamber 4, and the molding mold 902 is fixedly connected to the bottom of the inner wall of the mold base 901.

[0030] In this embodiment, the molding component 9 uses the mold base 901 to place and store the molding mold 902, thereby helping to shape the alumina fiber raw material and further improving the functionality of the device. The molding mold 902 is made of corrosion-resistant, easy-to-demold, and has certain strength and rigidity, such as stainless steel, engineering plastics (such as PVC, PP, PTFE), resin composite materials or coated metal, so as to help the mold withstand vacuum negative pressure.

The connecting base plate 1001 is fixedly connected to both sides of the inner wall of the vacuum chamber 4, and the protective shell 1002 is fixedly connected to the surface of the connecting base plate 1001.

[0036] In this embodiment, the demolding assembly 10 is fixed to both sides of the inner wall of the vacuum chamber 4 by the connecting base plate 1001, thereby providing a stable foundation. The protective shell 1002 can help protect the internal structure of the demolding assembly 10.

[0037] A dual-axis motor 1003 is fixedly connected to the center of the surface of the connecting base plate 1001, and multiple rotating shafts 1004 are arranged on both sides of the dual-axis motor 1003. A rotating striking block 1005 is fixedly connected to one end of the multiple rotating shafts 1004.

[0038] In this embodiment, the dual-axis motor 1003 can rotate using the rotating central shafts 1004 at both ends, thereby driving the rotating striking block 1005 to continuously rotate and strike the molding component 9. This vibration facilitates subsequent demolding and further improves the functionality and safety of the device.

[0039] Working Principle: The device operates via a control console 1, which supports the top structure, including the vacuum chamber 4, enhancing stability and safety.
