Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] By providing an RTM vacuum forming mold applicable to UV-CIPP in the embodiments of the present application, the problem that the existing RTM mold cannot accurately control the thickness of the product is solved, and the best mechanical properties of the UV-CIPP product are improved.

[0031] The technical solutions in the embodiments of the present application for solving the above technical problems are generally as follows:

[0032] As Figures 1-5 shown, by providing backing plates with different thicknesses, and realizing the detachable installation of the lower cover plate, the backing plate and the upper cover plate through a plurality of second bolts, it is convenient to replace the backing plate, realizes the accurate control of the thickness of the product by the RTM mold, is convenient to realize the optimal resin content of the product, and solves the problem that in the prior art, the RTM mold cannot accurately control the thickness of the product, affects the generation of the optimal resin content of the product, and further causes the product to not exert the best mechanical properties.

[0033] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0034] As Figure 1 、 Figures 3-5 shown, an RTM vacuum forming mold applicable to UV-CIPP includes a support base 101, a lower cover plate 10 and an upper cover plate 12, and the lower cover plate 10 is installed on the support base 101;

[0035] A window 124 is provided on the upper cover plate 12, and a tempered glass is installed in the window 124;

[0036] A spacer 11 is installed between the lower cover plate 10 and the upper cover plate 12;

[0037] The lower cover plate 10, the spacer 11 and the upper cover plate 12 are installed on the support base 101 through a plurality of second bolts 123;

[0038] A resin inlet hole 121 and an air extraction hole 122 are provided on the upper cover plate 12;

[0039] In different usage cases, the thickness of the spacer 11 installed between the lower cover plate 10 and the upper cover plate 12 is different.

[0040] By setting spacers 11 with different thicknesses and realizing the detachable installation of the lower cover plate 10, the spacer 11 and the upper cover plate 12 through a plurality of second bolts 123, it is convenient to replace the spacer 11, accurately control the thickness of the product by the RTM mold, facilitate the realization of the optimal resin content rate of the product, and solve the problem in the prior art that the RTM mold cannot accurately control the thickness of the product, affecting the generation of the optimal resin content rate of the product, and further resulting in the product not being able to exert the best mechanical properties.

[0041] During operation, resin is poured in through the resin inlet hole 121. By changing the amount of resin poured and the thickness of the glass fiber, the relationship between controlling the resin content rate change and the thickness is achieved. Ultraviolet rays penetrate the toughened glass in the ultraviolet penetration window 124, and the ultraviolet rays penetrate the toughened glass and enter the inside of the mold, which can further cause the UV-CIPP material to undergo a photocuring reaction to complete the production of the UV-CIPP material.

[0042] As Figures 2-4 shown, a first limit post 103 and a second limit post 104 are installed on the lower cover plate 10, a first limit hole 125 corresponding to the first limit post 103 is provided on the upper cover plate 12, and a second limit hole 126 corresponding to the second limit post 104 is further provided on the upper cover plate 12.

[0043] When the upper cover plate 12 is installed, the first limit hole 125 on the upper cover plate 12 is sleeved on the first limit post 103, and the second limit hole 126 on the upper cover plate 12 is sleeved on the second limit post 104. The installation of the upper cover plate 12 is preliminarily limited by the first limit post 103 and the second limit post 104 to ensure the stability of the upper cover plate 12 relative to the lower cover plate 10, and further facilitate the installation operation of the plurality of second bolts 123 passing through the upper cover plate 12.

[0044] As Figure 4 shown, the distances of the first limit post 103 and the second limit post 104 from the proximal end of the lower cover plate 10 are different.

[0045] By setting the first limiting post 103 and the second limiting post 104 to have different distances from the proximal end of the lower cover plate 10, the installation of the upper cover plate 12 can be controlled to be in only one direction, so that the glue inlet hole 121 and the air extraction hole 122 on the upper cover plate 12 are installed at the same position on the lower cover plate 10 each time, which is convenient for the injection structure and the air extraction structure required above the mold to correspond to the glue inlet hole 121 and the air extraction hole 122 one by one, and further facilitates the subsequent glue injection and air extraction operations.

[0046] As Figures 1-2 and Figure 4 shown, L-shaped plates 111 are installed on both sides of the support base 101. The L-shaped plates 111 are fixed to the support base 101 by corresponding first bolts 112. A clamping groove is formed on the side where the two L-shaped plates 111 are close to each other. The lower cover plate 10 is located in the clamping groove and is clamped with the support base 101.

[0047] By setting the L-shaped plates 111, the preliminary positioning of the lower cover plate 10 is realized, which is convenient for the installation of the lower cover plate 10.

[0048] As Figure 2 shown, the height of the L-shaped plate 111 on the side close to the lower cover plate 10 is greater than the thickness of the lower cover plate 10, which is convenient for the L-shaped plate 111 to limit the spacer plate 11 and further improves the installation stability of the spacer plate 11.

[0049] As Figure 2 and Figure 5 shown, a first groove 102 is formed on the side of the lower cover plate 10 close to the upper cover plate 12, and a second groove 127 corresponding to the first groove 102 is formed on the side of the upper cover plate 12 close to the lower cover plate 10. A rubber ring is filled in the mold, and the rubber ring is located in the first groove 102 and the second groove 127.

[0050] By setting the first groove 102 and the second groove 127 and filling a rubber ring in the first groove 102 and the second groove 127, the overall sealing performance of the mold is improved, which is convenient for the production of UV-CIPP products.

[0051] During use, the two L-shaped plates 111 are respectively installed on the corresponding two sides of the support base 101 through the first bolts 112. Then, the lower cover plate 10 is embedded in the two L-shaped plates 111, and the spacer plate 11 with the corresponding thickness is sleeved on the lower cover plate 10 through the first limiting post 103 and the second limiting post 104 and is located in the clamping groove formed by the two L-shaped plates 111;

[0052] Then, the first limiting hole 125 on the upper cover plate 12 is sleeved on the first limiting post 103, and the second limiting hole 126 on the upper cover plate 12 is sleeved on the second limiting post 104. Then, a plurality of second bolts 123 are used to pass through the upper cover plate 12, the backing plate 11, the lower cover plate 10 and the support seat 101 to complete the fixation among the upper cover plate 12, the backing plate 11, the lower cover plate 10 and the support seat 101. At this time, the glue inlet hole 121 is located below the glue inlet structure required by the mold, and the air extraction hole 122 is located below the air extraction hole 122 used by the mold. Glue is injected into the glue inlet hole 121 by the glue inlet structure. Then, the air inside the mold is evacuated through the air extraction hole 122 by the air extraction structure, so that the resin can fully infiltrate the internal glass fiber. After that, ultraviolet rays penetrate the tempered glass in the ultraviolet penetration window 124 and enter the mold interior, which can further cause the UV-CIPP material to undergo a photocuring reaction, completing the production of the UV-CIPP material.

[0053] In summary, compared with the prior art, the following beneficial effects are achieved:

[0054] 1. By setting the backing plate 11 with different thicknesses and realizing the detachable installation of the lower cover plate 10, the backing plate 11 and the upper cover plate 12 through a plurality of second bolts 123, it is convenient to replace the backing plate 11, realize the precise control of the thickness of the product by the RTM mold, facilitate the realization of the optimal resin content of the product, and solve the problem that in the prior art, the RTM mold cannot precisely control the thickness of the product, affecting the generation of the optimal resin content of the product, and further resulting in the product being unable to exert the best mechanical properties.

[0055] 2. By arranging the first limiting post 103 and the second limiting post 104 on the lower cover plate 12, the installation of the upper cover plate 12 is preliminarily limited by the first limiting post 103 and the second limiting post 104, ensuring the stability of the upper cover plate 12 relative to the lower cover plate 10, and thus facilitating the installation operation of a plurality of second bolts 123 passing through the upper cover plate 12.

[0056] 3. By setting the first limiting post 103 and the second limiting post 104 with different distances from the proximal end of the lower cover plate 10, the upper cover plate 12 can only be installed in one direction, and the glue inlet hole 121 and the air extraction hole 122 on the upper cover plate 12 are each installed at the same position on the lower cover plate 10 every time, facilitating the one-to-one correspondence between the glue injection structure and the air extraction structure required above the mold and the glue inlet hole 121 and the air extraction hole 122, and thus facilitating the subsequent glue injection and air extraction operations.
