DETAILED DESCRIPTION

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] Reference below Figures 1-6 The assembly device 100 for a vacuum pressure impregnation mold 200 according to an embodiment of the present invention is described. The impregnation mold 200 includes a plurality of mold units 201. The plurality of mold units 201 are assembled to define a mounting cavity 202 for mounting a magnet coil. Each mold unit 201 has an assembly flange 203. Any two adjacent mold units 201 assembled together are welded together via the assembly flanges 203 of the two mold units 201. The assembly device 100 includes: Multiple support mechanisms 10, multiple support mechanisms 10 are respectively used to support corresponding mold units 201, the support mechanisms 10 include: two support platforms 12 and two support plates 13, the two support platforms 12 are arranged to be spaced apart along the height direction of the support mechanism 10, the two support plates 13 are assembled between the two support platforms 12, the two support plates 13 are opposite and spaced apart along a first direction, so that the two support platforms 12 and the two support plates 13 jointly define an installation space for the corresponding mold unit 201 to pass through, the two support plates 13 are used to contact the corresponding mold unit 201, and the positions of the two support plates 13 relative to the support platforms 12 along the first direction are adjustable, and the first direction is perpendicular to the height direction of the support mechanism 10.

[0024] Among them, the assembly device 100 for the vacuum pressure impregnation mold 200 can be used in the manufacturing process of the magnet of the tokamak nuclear fusion device. During the vacuum pressure impregnation process, the impregnation mold 200 is required to provide an internal environment with good sealing. Since the size of the magnet coil is large and the impregnation mold 200 needs to wrap the magnet coil as a whole, the impregnation mold 200 needs to be divided into many blocks for on-site assembly welding. The length of the weld is as high as hundreds of meters, and the welding quality requirements are extremely high. It is necessary to ensure that the weld strength and quality meet the requirements of leak detection and vacuum pressure testing and that there are no problems with the weld when the subsequent vacuum pressure impregnation lasts for more than a month.

[0025] The impregnation mold 200 includes multiple mold units 201. In some embodiments of the present invention, the impregnation mold 200 may include two, three, four, ten, or other numbers of mold units 201, but the present invention is not limited thereto. The impregnation mold 200 may also include other numbers of mold units 201. As long as the impregnation mold 200 includes multiple mold units 201, the specific number of mold units 201 can be reasonably set according to the size of the magnet coil.

[0026] Multiple mold units 201 are assembled together to define an installation cavity 202 for installing a magnet coil. The magnet coil often has a symmetrical or irregular structure. Through the combination of multiple mold units 201, a special mold unit can be designed for the arc, stepped surface or irregular cross-section of the magnet coil to match the circular curved surface of the magnet coil and avoid local extrusion deformation.

[0027] like Figure 6 As shown, each mold unit 201 has an assembly flange 203. Any two adjacent mold units 201 that are assembled together are connected by overlapping welding of the assembly flanges 203 of the two mold units 201. This can replace the splicing welding method between the two mold units 201, thereby increasing the distance between the weld and the magnet coil in the installation cavity 202. This can reduce the impact of high welding temperatures on the magnet coil, prevent aging of the magnet coil insulation material or loss of superconducting properties, increase the structural strength of the immersion mold 200, reduce the risk of welding deformation, and solve the problem of oxidation on the back of the weld. In addition, the present invention uses a DC pulsed argon arc self-fluxing (wireless) welding method to weld the assembly flanges 203, which can effectively reduce welding heat input and further reduce the impact of high welding temperatures on the magnet coil.

[0028] The assembly device 100 includes: multiple support mechanisms 10. In some embodiments of the present invention, the assembly device 100 may include two, three, four, ten, or other numbers of support mechanisms 10, but the present invention is not limited thereto. The assembly device 100 may also include other numbers of support mechanisms 10, as long as the assembly device 100 includes multiple support mechanisms 10.

[0029] The number of support mechanisms 10 matches the number of mold units 201, and multiple support mechanisms 10 are used to support corresponding mold units 201. During welding, mold units 201 are susceptible to thermal deformation (e.g., bending and twisting) due to localized heating. The support mechanisms 10, through rigid fixation or flexible clamping, can limit the freedom of the mold units 201, reducing deformation and ensuring weld position accuracy. The support mechanisms 10 can also quickly dissipate welding heat, reducing temperature gradients in the weld and heat-affected zone, further minimizing the effects of high welding temperatures on the magnet coils. For large mold units 201, the support mechanisms 10 also have an anti-tilt function to prevent the mold units 201 from tipping over due to a shift in center of gravity during welding, thus avoiding casualties and equipment damage.

[0030] like Figure 2 As shown, the first direction is the X direction, which is perpendicular to the height direction of the support mechanism 10. The support mechanism 10 includes two support platforms 12 and two support plates 13. The support plates 13 and support platforms 12 are adapted to the shapes of the corresponding mold units 201, so that the support plates 13 and support platforms 12 fit the corresponding mold units 201, avoiding indentations on the mold units 201 caused by the support plates 13 and support platforms 12 due to shape mismatch, and improving the position accuracy of the corresponding mold units 201 to improve welding accuracy.

[0031] The two support platforms 12 are arranged to be spaced apart along the height direction of the support mechanism 10, and the two support plates 13 are assembled between the two support platforms 12. The two support plates 13 are opposite and spaced apart along the first direction, so that the two support platforms 12 and the two support plates 13 jointly define an installation space for the corresponding mold unit 201 to pass through. The two support plates 13 are used to contact the corresponding mold unit 201, and can confine the corresponding mold unit 201 within the support mechanism 10, thereby avoiding displacement of the corresponding mold unit 201 during welding and causing welding deformation.

[0032] Moreover, the positions of the two support plates 13 relative to the support platform 12 along the first direction are adjustable, which can further adjust the position of the corresponding mold unit 201 to ensure that the welding position of the mold unit 201 is accurate, thereby improving the welding quality and accuracy of the mold unit 201 and effectively reducing the risk of welding deformation and failure.

[0033] According to the assembly device 100 for the vacuum pressure impregnation mold 200 of the embodiment of the present invention, by welding any two adjacent mold units 201 that are assembled in cooperation with each other through the assembly flanges 203 of the two mold units 201, the structural strength of the impregnation mold 200 can be increased, and the spacing distance between the weld and the magnet coil can be increased, thereby solving problems such as oxidation on the back of the weld and high welding temperature affecting the magnet coil. By providing a support mechanism 10 to support the corresponding mold unit 201, the position of the corresponding mold unit 201 can be adjusted to ensure that the welding position of the mold unit 201 is accurate, thereby improving the welding quality and accuracy of the mold unit 201 and effectively reducing the risk of welding deformation and failure.

[0034] According to some embodiments of the present invention, Figure 2 As shown, the support mechanism 10 also includes: two position adjustment structures 20, which are arranged in a one-to-one correspondence with the two support plates 13, and the position adjustment structure 20 is used to adjust the position of the corresponding upper support plate 13 relative to the upper support platform 12 along the first direction.

[0035] Among them, such as Figure 2 As shown, the immersion mold 200 can be constructed as a ring-shaped or ring-like structure, one of the two support plates 13 is located on the inner ring surface of the immersion mold 200, and the other is located on the outer ring surface of the immersion mold 200, and the two support plates 13 are positioned correspondingly along the first direction to clamp the corresponding mold unit 201 in the two support plates 13, and the two position adjustment structures 20 are respectively located on the side of the two support plates 13 away from the immersion mold 200, and the position adjustment structure 20 is used to adjust the position of the corresponding support plate 13 relative to the upper support platform 12 along the first direction, and can adjust the position of the corresponding mold unit 201 relative to the upper support platform 12 along the first direction, and can further adjust the position of the corresponding mold unit 201 to ensure that the welding position of the mold unit 201 is accurate, thereby improving the welding quality and accuracy of the mold unit 201, and effectively reducing the risk of welding deformation and failure.

[0036] According to some embodiments of the present invention, the position adjustment structure 20 is located on a side of the corresponding support plate 13 facing away from the other support plate 13 , and the position adjustment structure 20 is fixed to at least one of the two support platforms 12 .

[0037] Among them, the position adjustment structure 20 is located on the side of the corresponding support plate 13 away from the other support plate 13, that is, the two position adjustment structures 20 are respectively located on the side of the two support plates 13 away from the immersion mold 200, so that the two position adjustment structures 20 can respectively adjust the position of the corresponding support plate 13 relative to the upper support platform 12 along the first direction, and then can adjust the position of the corresponding mold unit 201 relative to the upper support platform 12 in both directions along the first direction, further ensuring the accuracy of the welding position of the mold unit 201, and then can further improve the welding quality and accuracy of the mold unit 201, and effectively reduce the risk of welding deformation and failure.

[0038] The position adjustment structure 20 is fixed to at least one of the two support platforms 12. In some embodiments of the present invention, the position adjustment structure 20 can be fixed to the upper support platform 12, or the position adjustment structure 20 can be fixed to the lower support platform 12, or the position adjustment structure 20 can be fixed between the upper support platform 12 and the lower support platform 12. It can be reasonably set according to actual conditions. As a specific embodiment of the present invention, the position adjustment structure 20 can be fixed between the upper support platform 12 and the lower support platform 12. After the position of the corresponding mold unit 201 is adjusted by the position adjustment structure 20, by fixing the position adjustment structure 20 between the upper support platform 12 and the lower support platform 12, the corresponding mold unit 201 can be more firmly maintained at the precise welding position, avoiding displacement of the corresponding mold unit 201, and further improving the welding quality and accuracy of the mold unit 201, and further effectively reducing the risk of welding deformation and failure.

[0039] According to some embodiments of the present invention, Figure 2 As shown, the position adjustment structure 20 may include: a connecting column 21, the connecting column 21 extends along the height direction of the support mechanism 10, the connecting column 21 is fixed to at least one of the two support platforms 12, the connecting column 21 is provided with a first position adjustment portion 22, the first position adjustment portion 22 is passed through the connecting column 21 along the first direction, the first position adjustment portion 22 contacts the support plate 13 facing the end of the corresponding support plate 13, and moves along the first direction through the first position adjustment portion 22 to adjust the position of the corresponding support plate 13.

[0040] Among them, the connecting column 21 extends along the height direction of the support mechanism 10, and the connecting column 21 is fixed to at least one of the two support platforms 12. In an embodiment of the present invention, the connecting column 21 can be fixedly connected to one of the two support platforms 12, or the connecting column 21 can be fixedly connected to both support platforms 12, and can be reasonably set according to actual conditions.

[0041] As a specific embodiment of the present invention, the connecting column 21 is fixedly connected to both support platforms 12. Specifically, after the position of the connecting column 21 is adjusted to the desired position, the connecting column 21 is fixedly connected to both support platforms 12, which can more firmly maintain the connecting column 21 in the correct position, prevent the connecting column 21 from being displaced, and further improve the support stability and reliability of the support mechanism 10.

[0042] The connecting column 21 is provided with a first position adjustment portion 22, which can be constructed as a bolt, screw, or other structure. The first position adjustment portion 22 extends through the connecting column 21 along a first direction. The end of the first position adjustment portion 22 facing the corresponding support plate 13 contacts the support plate 13. By moving the first position adjustment portion 22 in the first direction, the corresponding support plate 13 can be moved in the first direction to adjust the position of the corresponding support plate 13.

[0043] Specifically, when the first position adjusting portion 22 moves toward the corresponding support plate 13 along the first direction, the end of the first position adjusting portion 22 facing the corresponding support plate 13 abuts against the support plate 13 and pushes the corresponding support plate 13 to move, and locks the corresponding support plate 13 in a determined position.

[0044] When the first position adjustment portion 22 moves away from the corresponding support plate 13 along the first direction, a gap can be generated between the end of the first position adjustment portion 22 facing the corresponding support plate 13 and the support plate 13, so that the support plate 13 can be movable relative to the first position adjustment portion 22, and the position of the corresponding support plate 13 can be readjusted.

[0045] According to some embodiments of the present invention, Figure 2 As shown, the connecting column 21 may be provided with a plurality of first position adjustment portions 22 , and the plurality of first position adjustment portions 22 are sequentially arranged along the height direction of the supporting mechanism 10 .

[0046] Among them, the connecting column 21 is provided with multiple first position adjustment parts 22. In some embodiments of the present invention, the connecting column 21 can be provided with two, three, four, etc. first position adjustment parts 22, but the present invention is not limited to this. The connecting column 21 can also be provided with other numbers of first position adjustment parts 22, as long as the connecting column 21 is provided with multiple first position adjustment parts 22.

[0047] The specific number of the first position adjustment parts 22 can be reasonably set according to the length of the connecting column 21. As a specific embodiment of the present invention, there can be five first position adjustment parts 22, and the five first position adjustment parts 22 are evenly arranged in sequence along the height direction of the support mechanism 10. With such a setting, the position of the connecting column 21 can be evenly adjusted along the first direction to avoid the position displacement of the connecting column 21 due to excessive local fastening force, thereby ensuring the uniformity of the supporting force of the support plate 13, so as to adjust the corresponding mold unit 201 to the accurate position and play a role in supporting the corresponding mold unit 201.

[0049] Among them, the connecting column 21 can be formed with a threaded hole, the first position adjustment part 22 is an adjusting rod, the outer peripheral wall of the adjusting rod is formed with an external thread, the adjusting rod is passed through the threaded hole, and the adjusting rod is moved along the first direction by rotating the adjusting rod. It can be directly adjusted manually without setting up an external driving device, which can effectively reduce the position adjustment cost of the connecting column 21, and the thread adjustment accuracy is relatively high, which is conducive to improving the position adjustment accuracy of the support plate 13, and then can indirectly improve the position adjustment accuracy of the corresponding mold unit 201, so as to effectively improve the welding position accuracy of the corresponding mold unit 201.

[0050] According to some embodiments of the present invention, the connecting column 21 and the corresponding support plate 13 are parallel, so that each connecting column 21 can accurately adjust the corresponding support plate 13, and can further effectively ensure that the support plate 13 fits the corresponding mold unit 201. It can not only further improve the position accuracy of the corresponding mold unit 201 to improve the welding accuracy, but also reduce the risk of the support plate 13 causing indentations on the mold unit 201.

[0051] According to some embodiments of the present invention, Figure 2 As shown, the connecting column 21 is located between the two support platforms 12, a first mounting hole is formed at the end of the connecting column 21, and a second mounting hole is formed at the support platform 12. The first mounting hole and the second mounting hole are opposite to each other along the height direction of the support mechanism 10, and a first fastener 25 is passed through the second mounting hole and assembled to the first mounting hole to fix the connecting column 21 to the corresponding support platform 12.

[0052] Among them, the connecting column 21 is located between the two support platforms 12, and a first mounting hole is formed at the end of the connecting column 21, and a second mounting hole is formed at the support platform 12. The first mounting hole and the second mounting hole are opposite to each other along the height direction of the support mechanism 10.

It can not only fix the connecting column 21 more stably, but also limit the displacement of the support plate 13 and the connecting column 21 along the height direction of the support mechanism 10 through the support platform 12, thereby stably defining the installation space for the corresponding mold unit 201 to pass through.

[0053] According to some embodiments of the present invention, Figure 2 As shown, at least one end of the connecting column 21 is provided with a mounting plate 23, and the mounting plate 23 and the side edge of the corresponding side support platform 12 are opposite and spaced apart, and the mounting plate 23 is provided with a plurality of second position adjustment parts 24, and the plurality of second position adjustment parts 24 are arranged along the side edge, and each second position adjustment part 24 contacts the support platform 12 at the end facing the corresponding support platform 12, and the connecting column 21 is rotated around the height direction of the support mechanism 10 by moving the second position adjustment part 24 toward or away from the corresponding support platform 12 to adjust the relative position of the connecting column 21 and the corresponding support plate 13.

Each second position adjustment part 24 contacts the support platform 12 at the end facing the corresponding support platform 12, and the connecting column 21 is rotated around the height direction of the support mechanism 10 by moving the second position adjustment part 24 toward or away from the corresponding support platform 12 to adjust the relative position of the connecting column 21 and the corresponding support plate 13.

[0057] Specifically, when one of the two second position adjustment parts 24 moves toward the corresponding support platform 12, the connecting column 21 rotates around the height direction of the support mechanism 10 toward this second position adjustment part 24. When one of the two second position adjustment parts 24 moves away from the corresponding support platform 12, the connecting column 21 rotates around the height direction of the support mechanism 10 toward the other second position adjustment part 24 to adjust the circumferential position of the connecting column 21 along the corresponding support plate 13 to ensure that the connecting column 21 is parallel to the corresponding support plate 13, thereby ensuring that the corresponding support plate 13 and the corresponding mold unit 201 are fitted.

In some embodiments of the present invention, the support platform 12 and the support seat 14 can be fixedly connected by threads, or the support platform 12 and the support seat 14 can be fixedly connected by a sliding mechanism, but the present invention is not limited to this. The support platform 12 and the support seat 14 can also be fixedly connected by other means, as long as the support platform 12 located below is fixed with a support seat 14.

[0060] The length of the support seat 14 along the height direction of the support mechanism 10 is adjustable to adjust the height of the support platform 12 below. The height of the support mechanism 10 can be adjusted so that the height of the support platform 12 located below matches the bottom surface of the corresponding mold unit 201, and thus can be suitable for immersion molds 200 of different shapes, which can effectively improve the versatility of the support mechanism 10.

[0061] According to some embodiments of the present invention, the shape of the support plate 13 is adapted to the shape of the corresponding mold unit 201, so that the support plate 13 fits the corresponding mold unit 201 during assembly, avoiding indentations caused by the support plate 13 on the mold unit 201 due to shape mismatch. Furthermore, the full contact surface support of the support plate 13 can suppress vibration and deviation of the mold unit 201, reducing the risk of deformation of the mold unit 201. It can also optimize stress distribution, reduce low-welding deformation and residual stress, and thus improve welding quality and reduce welding defect rates.

[0062] According to some embodiments of the present invention, Figure 4 and Figure 5As shown, the assembly device 100 may also include: a limiting mechanism 30, the limiting mechanism 30 forms a limited space 31, the limiting space 31 is used to assemble the assembly flanges 203 of two adjacent mold units 201 that are assembled in cooperation with each other, so that the limiting mechanism 30 limits the assembly flanges 203 of the two adjacent mold units 201 to move away from each other, and the limiting mechanism 30 is fixed to at least one support plate 13.

[0063] Among them, the limiting mechanism 30 forms a limited space 31. After the assembly flanges 203 of two adjacent mold units 201 that are assembled in cooperation with each other are welded, the limiting space 31 is used to assemble the assembly flanges 203 of two adjacent mold units 201 that are assembled in cooperation with each other, so that the limiting mechanism 30 limits the assembly flanges 203 of the two adjacent mold units 201 from moving away from each other, which is used to reduce the instability of the welds of the corresponding mold units 201 during vacuum pressure impregnation, and prevent the welds of the assembly flanges 203 from being damaged due to the increase in internal pressure.

[0064] The limiting mechanism 30 is fixed to at least one support plate 13. The limiting mechanism 30 can be fixed to one support plate 13 or to multiple support plates 13 simultaneously, and can be appropriately configured based on actual conditions. The limiting mechanism 30 is fixed to at least one support plate 13 to secure the position of the limiting mechanism 30, thereby enabling the limiting mechanism 30 to stably limit the assembly flanges 203 of two adjacent mold units 201 that are assembled together. This also prevents the limiting mechanism 30 from being stretched apart by the weld seam of the assembly flanges 203 and falling off the assembly flanges 203.

[0065] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the limiting mechanism 30 includes: a fixed plate 32, a first clamping plate 33 and a second clamping plate 34, the first clamping plate 33 and the second clamping plate 34 are opposite and spaced apart, the first clamping plate 33 and the second clamping plate 34 are parallel to each other, the first clamping plate 33 and the second clamping plate 34 are located on the same side of the fixed plate 32 and are fixed to the fixed plate 32, so that the fixed plate 32, the first clamping plate 33 and the second clamping plate 34 jointly define the limiting space 31.

[0066] Among them, the fixing plate 32, the first clamping plate 33 and the second clamping plate 34 can all be made of steel plates, the first clamping plate 33 and the second clamping plate 34 are opposite and spaced apart, the first clamping plate 33 and the second clamping plate 34 are parallel to each other, the first clamping plate 33 and the second clamping plate 34 are located on the same side of the fixing plate 32 and are fixed to the fixing plate 32. In some embodiments of the present invention, the first clamping plate 33, the second clamping plate 34 and the fixing plate 32 can be integrally formed, or the first clamping plate 33, the second clamping plate 34 and the fixing plate 32 can be fixedly connected by welding or bolts, as long as the first clamping plate 33 and the second clamping plate 34 are located on the same side of the fixing plate 32 and are fixed to the fixing plate 32.

[0067] The fixing plate 32, the first clamping plate 33 and the second clamping plate 34 jointly define a limiting space 31. The sizes of the first clamping plate 33 and the second clamping plate 34 are adapted to the sizes of the corresponding assembly flange 203, so as to limit the corresponding assembly flange 203 as a whole within the limiting space 31, which can further reduce the instability of the weld of the corresponding mold unit 201 during vacuum pressure impregnation, and prevent the weld of the assembly flange 203 from being damaged due to the increase in internal pressure, thereby effectively improving the reliability and service life of the impregnation mold 200.

[0068] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the limiting mechanism 30 may further include: a fixing block 35 , which is fixed to at least one of the fixing plate 32 , the first clamping plate 33 and the second clamping plate 34 , and is fixed to the corresponding support plate 13 by a second fastener.

[0069] Among them, the fixed block 35 is fixed to at least one of the fixed plate 32, the first clamping plate 33 and the second clamping plate 34. In some embodiments of the present invention, the fixed block 35 can be fixed to the fixed plate 32, or the fixed block 35 can be fixed to the first clamping plate 33, or the fixed block 35 can be fixed to the second clamping plate 34, or the fixed block 35 is fixed to two of the fixed plate 32, the first clamping plate 33 and the second clamping plate 34, or the fixed block 35 is fixedly connected to the fixed plate 32, the first clamping plate 33 and the second clamping plate 34, and can be reasonably set according to actual conditions.

[0070] After the limiting mechanism 30 is assembled with the corresponding assembly flange 203, the fixing block 35 is fixed to the corresponding support plate 13 by the second fastener to fix the position of the limiting mechanism 30, so that the limiting mechanism 30 can stably limit the assembly flanges 203 of the two adjacent mold units 201 that are assembled with each other, and can also prevent the limiting mechanism 30 from being stretched open by the weld of the assembly flange 203 and falling off from the assembly flange 203.

[0071] Furthermore, the specific process of the present invention can be: (1) If Figure 6 As shown, the mold module is blanked to produce the assembly flange 203. The length of the assembly flange 203 can be reasonably set according to actual conditions. As a specific embodiment of the present invention, the length of the assembly flange 203 can be 30 mm.

[0072] (2) If Figure 1 As shown, the immersion mold 200 composed of the mold units 201 is hoisted onto the working platform as a whole.

[0073] (3) If Figure 2 As shown, the support mechanism 10 is assembled with the immersion mold 200 , each mold unit 201 is adjusted to a precise position, and a position for welding the assembly flange 203 is reserved.

[0074] (4) The position of the assembly flange 203 is adjusted. When there is a gap between any two adjacent mold units 201 that are assembled in coordination with each other, a thin stainless steel sheet is used to fill it and then spot welded. The spot welding spacing is 50 mm, and the number of spot welds is as large as possible. After the spot welding is completed, DC pulse argon arc welding (without adding wire) is used for self-melting welding. The welding is symmetrical. The welding sequence is: vertical weld on the outer side (continuous welding from bottom to top), vertical weld on the inner side (continuous welding from bottom to top), upper horizontal weld, lower horizontal weld, and T-weld.

[0075] (5) After welding is completed, non-destructive testing (visual inspection, penetration, leak detection, pressure test) is carried out.

[0076] (6) If Figure 3 As shown, the limiting mechanism 30 is assembled with the assembly flange 203 and the support plate 13 .

[0077] (7) The impregnation mold 200 needs to wrap the entire magnet coil and perform vacuum pressure impregnation.

[0078] In this way, the structural strength of the impregnation mold 200 can be increased, and the distance between the weld and the magnet coil can be increased, solving problems such as oxidation on the back of the weld and the impact of high welding temperature on the magnet coil. By providing a support mechanism 10 to support the corresponding mold unit 201, the position of the corresponding mold unit 201 can be adjusted to ensure the accurate welding position of the mold unit 201, thereby improving the welding quality and accuracy of the mold unit 201 and effectively reducing the risk of welding deformation and failure. The limiting mechanism 30 can also limit the assembly flanges 203 of two adjacent mold units 201 from moving away from each other, thereby reducing the instability of the welds of the corresponding mold units 201 during vacuum pressure impregnation and preventing the welds of the assembly flanges 203 from being damaged due to increased internal pressure. This ensures that the assembly flanges 203 will not fail under long-term and complex working conditions, and the support mechanism 10 and the limiting mechanism 30 are easy to disassemble and reuse.
