[0034] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0035] like Figure 1 to Figure 2 As shown: This embodiment provides a dual-purpose integrated mold for a cabin cover upper sheet, including a mold body 100 used for the production of a tail wing version of the cabin cover, the mold body 100 is provided with a mounting portion 101 for mounting the tail wing, the mounting portion 101 is a trough structure, the mounting portion 101 is provided with a mold platform 200 detachably connected thereto, the mold platform 200 is used to cover the original structural foundation inside the mounting portion 101, and the production and use of a tailless version of the cabin cover is realized through the mold platform 200, wherein the specific structure of the mold platform 200 and its structure for use in conjunction with the mold body 100 are described as follows.

[0036] like Figures 3 to 9As shown: the mold platform 200 includes a platform panel 201, a support bracket 202 and a protective plate 203 that are interconnected. The platform panel 201 is located at the upper part. The structure of the platform panel 201 is determined according to the installation requirements of the tailless version of the nacelle cover. The support bracket 202 is made of welded steel as a whole. The protective plate 203 is located at the bottom. The protective plate 203 is made of nylon plate and is distributed at the contact and connection position between the mounting bracket and the inner wall of the mounting part 101. Since the hardness of the protective plate 203 is reduced, scratches and damages to the inner wall of the mounting part 101 can be avoided. The three components of the mold platform 200 are connected by screws. The screws pass through the protective plate 203 and the support bracket 202 from the bottom surface respectively. Finally, the ends of the screws are connected and fixed to the platform panel 201. The ends of the screws are located inside the platform panel 201. The screw connection can solve the influence of welding deformation on the flatness of the plate surface, ensure the flatness of the upper surface of the platform panel 201, and do not affect the molding and use of the product.

[0037] When assembled with the mounting portion 101, the mold platform 200 is placed inside the mounting portion 101, and the platform panel 201 is arranged to face outward, the protective plate 203 is connected to the bottom surface of the mounting portion 101 to form the overall support base of the mold platform 200, and a mounting hole is also provided on the bottom surface of the mounting portion 101, and the support bracket 202 is connected to the inner wall of the mounting portion 101 through a bolt 500 in the mounting hole, and the bolt 500 enters the mounting portion 101 from the back side of the mold body 100, and then is connected and fixed to the mold platform 200, so that the support bracket 202 and the mold body 100 are connected to each other as an integral structure;

[0038] At the same time, the edge of the platform panel 201 matches the shape of the inner wall of the mounting portion 101 and is tightly connected to each other, and a structural surface for mounting the tailless version of the nacelle cover is formed between the platform panel 201 and the inner wall of the mounting portion 101, thereby meeting the production and use requirements of the tailless version of the nacelle cover.

[0039] Furthermore, in the above-mentioned assembly process, a gap portion is further provided between the bottom surface of the mold platform 200 and the inner wall of the mounting portion 101, and a filler 300 is provided inside the gap portion, and the filler 300 is made of polyurethane foam. At the same time, two through holes 205 are provided on the platform panel 201, and the through holes 205 are connected to the gap portion. After the assembly is completed, the foaming composite material can be injected into the gap through the through holes 205 to form a polyurethane foam. After the filler 300 is formed, the shape is consistent with the inner wall of the gap. The filler 300 is kept in uniform contact with the inner wall of the mounting portion 101 and the bottom surface of the mold platform 200. When in use, the inner surface of the mounting portion 101 can be evenly stressed, thereby protecting the inner surface of the mold body 100. At the same time, after the foaming molding is completed, a hanging ring 204 detachably connected to it is installed in the through hole 205. The hanging ring 204 is arranged through the through hole 205 and is connected and fixed to the supporting bracket 202. The hanging ring 204 can seal the through hole 205 and can be used for hanging the mold body 100 without affecting the surface quality of the product.

[0040] Furthermore, a sandblasting layer connected to the outer wall of the support bracket 202 is provided to enhance the bonding strength with the filler 300 and ensure the integrity of the structure.

[0041] Furthermore, a demoulding layer connected to the inner wall of the mounting portion 101 is provided, and the demoulding layer includes a demoulding agent layer and a plastic film layer 700, and the demoulding agent layer is located between the inner wall of the mounting portion 101 and the plastic film layer 700. When in use, a thin layer of demoulding wax is first applied to the inner wall of the mounting portion 101 to form a demoulding agent layer, and the demoulding wax should cover the installation position of the bolt 500, and then a layer of foamed plastic film is applied, and the foamed plastic film has a thickness of 0.03 mm to form the plastic film layer 700, which is easy to remove during demoulding, and finally the bolts 500 are installed to fix the mold platform 200;

[0042] At the same time, a sealing block 400 is arranged on the back surface of the mold platform 200. The sealing block 400 is formed by curing a weather-resistant sealant. The sealing block 400 is wrapped around the outer side of the mounting hole and the outer end of the bolt 500 located in the mounting hole, and is respectively tightly connected to the mold platform 200 and the bolt 500, so that the installation position of the bolt 500 is tightly arranged, and there will be no air leakage or pressure release at this position during the product production process.

[0043] Among them, with regard to the structure of the mounting hole, taking into account the use of the mold body 100 after the mold platform 200 is disassembled, one end of the mounting hole close to the inner wall of the mounting portion 101 is an open trumpet-shaped structure. When assembled with the bolt 500, the internal gap of the trumpet-shaped structure can be filled with mold release wax to achieve a sealed filling.

[0044] After the mold platform 200 is disassembled, when the mold body 100 is used for the production of the tail wing version of the nacelle cover, the structure of the mounting portion 101 is applicable, but the position of the mounting hole does not meet the production requirements. At this time, a threaded plug 600 connected to the mounting hole is provided inside the mounting hole, and the shape of the corresponding end of the threaded plug 600 is the same as the shape of the inner wall of the mounting hole, so that when it rotates, a sealing and positioning effect is formed through the inner wall of the mounting hole with a trumpet-shaped structure. At the same time, the end of the threaded plug 600 covers the mounting hole, and the inner end of the threaded plug 600 and the surface of the mounting portion 101 are located in the same structural plane, so as to maintain the flatness of the inner wall of the mounting portion 101 and meet the production and use requirements of the tail wing version of the nacelle cover;

[0045] At the same time, a sealing block 400 is arranged on the back surface of the mold body 100, and the sealing block 400 is wrapped around the outer side of the mounting hole and the outer end of the threaded plug 600 located in the mounting hole. The sealing block 400 has the same structure and purpose as those used when assembling the bolts 500, and meets the production and use needs of the tail wing version cabin cover.

[0046] The above descriptions are only preferred implementation modes of the present invention. As long as the technical solutions for the purpose of the present invention are achieved by substantially the same means, they are all within the protection scope of the present invention.
