Description

Technical Field

[0001] This invention relates to the field of radome molding molds, and more specifically, to a high-strength radome integral molding mold and molding method with metal inserts. Background Technology

[0002] A radome creates a closed space around a communication antenna to protect the antenna system from wind, sand, rain, snow, and hail, and mitigate the effects of sudden temperature changes, solar radiation, humidity, salt spray, and other environmental conditions. This requires the radome to have sufficient strength and corrosion resistance. To improve the reliability of the radome's connection to other equipment, metal inserts need to be designed at the connection points between the radome and external devices.

[0003] Existing technology patent application CN202122743222.0 discloses a combined mold for auxiliary molding of composite material radomes, including an inner mold and a bottom mold, which are detachably connected. The inner mold includes a hemispherical protrusion. When the inner mold and the bottom mold are connected, the edge of the hemispherical protrusion connects with the surface of the bottom mold, and the connection is smooth and continuous. Although this patent can mold the composite material part of a composite material radome, this radome mold cannot mold radomes with metal inserts, and due to the lack of support during demolding, it can cause inconvenience in demolding and even damage to the product.

[0004] The prior art patent CN202221629113.4 discloses a composite mold for integral molding of dome radomes, including an outer mold base, an inner mold base inside the outer mold base, a liquid guide pipe at the bottom of the inner cooling cavity, and a material guide mold frame at the bottom of the outer mold base, with a feed hopper fixedly connected to the bottom end of the material guide mold frame. Although this patent uses a casting molding method composed of inner and outer molds to manufacture radomes, improving processing efficiency, the radomes produced by this process have low fiber content and low strength, and it also cannot form radomes with metal inserts.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0048] Base 4;

[0049] Support body 3 is used to support the main mold body 1. The support body 3 is installed between the main mold body 1 and the base 4. A demolding hole 6 is provided on the support body 3. The demolding hole 6 can serve as a force point for the antenna cover 7 during the demolding process, making demolding easier.

[0050] Fixing member 2: A fixing part 11 is provided at the lower end of the main mold body 1. The fixing member 2 is installed above the fixing part 11 and is used to fix the metal insert 8.

[0051] The high-strength radome integral molding mold 100 with metal inserts described in this embodiment can mold radomes with metal inserts on the one hand, and facilitate demolding on the other hand, avoiding damage to the product.

[0052] Specifically, the metal insert 8 is detachably connected to the fixing member 2.

[0053] This setting facilitates demolding.

[0054] Specifically, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a first mounting hole 21 is provided on the fixing member 2, and a fourth mounting hole and a first central hole are provided on the metal insert 8. The metal insert 8 is sleeved on the main mold body 1 through the first central hole. The first connecting member 91 passes through the first mounting hole 21 and the fourth mounting hole in sequence to connect the metal insert 8 to the fixing member 2.

[0055] Specifically, the fastener 2 is not limited.

[0056] The fixing element 2 is a fixing ring.

[0057] Specifically, the first connector 91 is not specifically limited.

[0058] More specifically, in this embodiment, the first connector 91 is configured as a bolt.

[0059] Specifically, the fixing member 2 is detachably connected to the fixing part 11.

[0060] This setting facilitates demolding.

[0061] Specifically, such as Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a second mounting hole is provided on the fixing part 11, and a third mounting hole 22 and a second central hole 23 are provided on the fixing member 2. The fixing member 2 is sleeved on the main mold body 1 through the second central hole 23. The second connecting member 92 passes through the second mounting hole and the third mounting hole 22 in sequence to connect the fixing member 2 to the fixing part 11.

[0062] Specifically, the fixing part 11 is provided in multiple ways, and the multiple fixing parts 11 are evenly arranged below the main mold body 1.

[0063] Specifically, the second connector 92 is not specifically limited.

[0064] More specifically, in this embodiment, the second connector 92 is configured as a bolt.

[0065] Specifically, the support body 3 is detachably connected to the main mold body 1.

[0066] More specifically, the main mold body 1 is configured as a hollow structure, a first thread is provided in the cavity of the main mold body 1, and a second thread is provided on the outside of the support body 3, wherein the first thread and the second thread are screwed together.

[0067] Specifically, such as Figures 1-7 As shown, a handrail assembly 5 is provided on the mold 100, and the handrail assembly 5 is mounted on the support body 3.

[0068] This setting facilitates the later handling of mold 100.

[0069] More specifically, such as Figure 1 As shown, the handrail assembly 5 includes a first handrail plate 51, a second handrail plate 52, and a first connecting plate 53. A fourth mounting hole is provided on the support body 3. The first connecting plate 53 is installed on the support body 3 through the fourth mounting hole.

[0072] Specifically, such as Figure 1As shown, a fifth mounting hole is provided on the mounting plate 42, and the support 3 is mounted on the base 4 through the fifth mounting hole.

[0073] This arrangement facilitates the mounting of the support 3 onto the base 4.

[0074] This embodiment also proposes a method for integrally molding a high-strength radome with metal inserts. The method uses any one of the high-strength radome integral molding molds 100 described above, and includes the following steps:

[0075] S1, Assembly mold 100;

[0076] S2. Form the radome 7 with metal inserts 8 on the mold 100;

[0077] S3, Demolding.

[0078] Steps S1 to S3 are interconnected and inseparable. Through steps S1 to S3, a high-strength radome 7 with metal inserts 8 can be produced on mold 100. It is high-strength, corrosion-resistant, and has reliable connections.

[0079] Specifically, step S1 includes the following steps:

[0080] S11. Install the support 3 into the base 4;

[0081] S12. Install the main mold body 1 onto the support body 3;

[0082] S13. Install the fastener 2 above the fixing part 11 of the main mold body 1;

[0083] S14. Install handrail assembly 5 on support body 3.

[0084] Steps S11 to S14 are interconnected and inseparable. Mold 100 can be quickly installed through steps S11 to S14.

[0085] Specifically, step S2 includes the following steps:

[0086] S21. Cleaning the mold 100: Wipe the molding mold 100 with a non-woven cloth dipped in detergent to ensure that the mold 100 is clean and free of oil stains, and then apply an appropriate amount of mold release agent to the mold 100.

[0087] S22, Installation of metal insert 8: Install the metal insert 8 of the radome 7 onto the fixing part 2;

[0088] S23. Fiber cloth laying: Lay the cut fiber cloth on the radome forming mold 100, and then use shaping spray adhesive to fix the fiber cloth, ensuring that the fiber cloth is free of wrinkles, bridging and other phenomena; then continue to lay layers and repeat the above steps until the number of layers specified in the lay-up design is completed.

[0089] S24. Sealing: Lay a release cloth, glue injection tube, and air extraction tube on the surface of the completed fiber cloth; finally, use a high-temperature resistant bag film with sealing tape to completely seal the fiber cloth.

[0090] S25. Resin introduction: The prepared resin is introduced into the fiber cloth through the injection tube to ensure that the resin fully impregnates the fiber cloth. After impregnation, the injection tube is closed and the vacuum state is maintained until the resin is completely cured, thereby forming the antenna cover 7 with metal insert 8.

[0091] Alternatively, specifically, step S2 includes the following steps:

[0092] S21. Cleaning the mold 100: Wipe the molding mold 100 with a non-woven cloth dipped in detergent to ensure that the mold 100 is clean and free of oil stains, and then apply an appropriate amount of mold release agent to the mold 100.

[0093] S22, Installation of metal insert 8: Install the metal insert 8 of the radome 7 onto the fixing part 2;

[0094] S23. Prepreg Laying: Lay the cut single-layer prepreg onto the radome forming mold 100, and then use a prepreg layup roller to roll back and forth on the surface of the prepreg to ensure that there are no wrinkles or bridging after the prepreg is rolled; then continue to lay up and repeat the above steps until the number of layers specified in the layup design is completed.

[0095] S24. Prepreg sealing: A perforated release membrane is laid on the surface of the prepreg after the layers are laid. An absorbent felt is then laid on the surface of the perforated release membrane. A vacuum nozzle is placed above the absorbent felt. Finally, a high-temperature resistant release membrane is used in conjunction with sealing tape to completely seal the prepreg.

[0096] S25. Curing stage: Install the vacuum quick connector on the vacuum nozzle to draw a vacuum, and after ensuring that the bag film does not leak, heat and cure the product according to the set program to form the radome 7 with metal insert 8.

[0097] Steps S21 to S25 are interconnected and inseparable. Through steps S21 to S25, a high-strength radome 7 with metal inserts 8 can be produced on mold 100. It is high-strength, corrosion-resistant, and has reliable connections.

[0098] Specifically, step S3 includes the following steps:

[0099] S31. Remove the second connecting piece 92, and the connection between the fixing piece 2 and the fixing part 11 is broken.

[0100] S32. Remove the handrail assembly 5 and the base 4;

[0101] S33. Then fix the bottom surface of the fixing part 2, and use a tool to apply a pulling force through the demolding hole 6 toward the side away from the antenna cover 7 to separate the main mold body 1, the fixing part 2 and the antenna cover 7 with metal insert 8.

[0102] S34. Then, by separating the fastener 2 and the radome 7 with the metal insert 8, a high-strength radome 7 with the metal insert 8, which is high-strength, corrosion-resistant, and has reliable connections, can be obtained.

[0103] Steps S31 to S34 are interconnected and inseparable. Through steps S31 to S34, the high-strength radome 7 with metal inserts 8 can be smoothly separated from the main mold body 1 of the mold 100. First, the demolding operation is convenient and quick, improving product production efficiency. Second, the stress-bearing parts of the demolding process are reasonably designed, which is beneficial to the protection of the main body of the radome 7. Third, the product yield is improved. The radome 7 products made using this invention have a smooth demolding operation, avoiding damage to the radome 7 products during demolding. After actual application operation tests, the product yield is over 99.9%.

[0104] Compared to existing technologies, the high-strength radome integral molding mold 100 with metal inserts described in this embodiment is interconnected with and inseparable from the molding method, playing multiple roles:

[0105] 1) The high-strength radome integral molding mold and molding method with metal inserts described in this embodiment can mold an radome 7 with metal inserts 8.

[0106] 2) The high-strength radome integral molding mold and molding method with metal inserts described in this embodiment are easy to demold and avoid damage to the product.

[0107] 3) The high-strength radome integral molding mold and molding method with metal inserts described in this embodiment can produce a high-strength radome 7 with metal inserts 8 that is high-strength, corrosion-resistant and reliably connected.

[0108] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
