[0003] Mold design is one of the key steps in the manufacturing of composite material launch tubes, and the mold structure directly affects the various performance indicators of the launch tube. Because the composite material layers are relatively large after being laid on the core mold, they are often difficult to fit into the outer mold, which affects the quality of the manufactured part and results in poor control over the dimensional accuracy of the launch tube part.

[0008] Preferably, the first inclined surface, the second inclined surface, the third inclined surface, the fourth inclined surface, the fifth inclined surface, and the sixth inclined surface all form a 45° angle with the horizontal plane.

[0015] Preferably, the substrate has an opening on its upper part, allowing the core mold with the launch tube component to be placed into the receiving channel through the opening.

[0016] Compared with the prior art, the present invention has achieved the following technical effects:

[0017] The composite material launch tube manufacturing device provided by this invention uses an outer mold consisting of a base, an upper mold, a lower mold, and two side molds. After the upper layer of the core mold is laid, the loose fabric layer results in an excessively large size, making it difficult to install. To address this, each mold is fitted with a corresponding inclined surface. The distance between the two side molds is adjustable to accommodate the dimensions of the laid-up core mold. The upper mold is then pressed down using clamping bolts. During this pressing process, the upper mold, side molds, and lower mold come close together to achieve a proper fit, ensuring the external dimensions of the launch tube component are formed. Each inclined surface faces the axis of the core mold, allowing for automatic inward contraction when the clamping bolts are tightened, thus ensuring the dimensional accuracy of the launch tube component. During manufacturing, the layered material is first laid on the core mold, and then the outer mold is wrapped around it. After completion, the outer mold can be removed piece by piece, leaving only the launch tube component and the core mold. The core mold can then be extracted from the launch tube component, making demolding simple and convenient.

[0018] Furthermore, the lifting module, in conjunction with the lifting groove, can slide upward along the lifting slope by rotating the set screw and based on the contact between the end of the set screw and the base. This causes the side molds to move upward and outward along the direction of the lifting slope, thereby increasing the distance between the two side molds. This makes it easier to insert the core mold into the outer mold after the laying is completed. It also makes it easier to demold the outer mold after the launch tube component is manufactured.

[0019] Furthermore, setting each inclined surface to 45° enables gapless movement between molds during the molding process, avoiding edge and fabric compression during mold closing; when each inclined surface forms a 45° angle, adjacent parts can fit together better during assembly.

[0020] Furthermore, the positioning frame in the end assembly can be detachably fixed to the shaft head. When it is necessary to install or replace the mandrel, the positioning frame can be easily removed or installed from the shaft head, improving operational flexibility. The positioning frame in the end assembly seals the end of the launching tube part molding gap, playing a positioning and sealing role. The positioning frame can ensure the accurate position of the mandrel during the launching tube part molding process, thereby ensuring the dimensional accuracy of the launching tube, such as length and diameter. The shaft head is fixed to the end of the mandrel, providing stable support for the positioning frame, so that the positioning frame can firmly seal the end of the molding gap, preventing positional displacement during composite material injection and curing, and further improving the accuracy of the molding dimensions.

[0021] Furthermore, the bearings installed on the shaft head allow the core mold to rotate with the assistance of the support during core mold layering, facilitating the layering operation.

[0022] Furthermore, the positioning frame is connected to the core through a slotted connecting plate and a connecting block, making it simple and convenient to assemble and disassemble.

[0023] Furthermore, the cooperation between the guide rail and the guide rail positioning groove ensures the correct position of the core mold.

[0024] Furthermore, the connection slot facilitates its connection and cooperation with the demolding device to achieve demolding.

[0025] Furthermore, the demolding device uses hydraulic connecting rods as a power source. The hydraulic system can provide strong and stable pulling force. During the demolding process, the two hydraulic connecting rods can apply force simultaneously to achieve efficient demolding. The hydraulic system can achieve precise force control and stroke adjustment. During the demolding process, the output force and stroke of the hydraulic connecting rods can be adjusted according to different part requirements and demolding difficulty to ensure a smooth and safe demolding process and avoid damage to the parts.

[0026] Furthermore, the opening design makes it easier to place the core mold containing the launch tube component into the receiving channel, and also facilitates direct observation of the component during the core mold demolding process, ensuring the stability of the component during demolding.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The purpose of this invention is to provide a composite material launch tube manufacturing device to solve the problems existing in the prior art, making the manufacturing process simpler and more convenient, ensuring the molding dimensional accuracy of the launch tube parts, and facilitating demolding.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Example 1

[0044] This embodiment provides a composite material launch tube manufacturing device, such as... Figures 1 to 8 As shown, it includes a molding die; the molding die includes a core mold 10 and an outer mold 20; the core mold 10 is fitted inside the outer mold 20, and the circumferential gap between the core mold 10 and the outer mold 20 forms the molding gap for the launch tube component; the outer mold 20 includes a base 21, an upper mold 22, a lower mold 23, and two side molds 24; a support groove 211 is provided on the base 21, and the lower ends of the two side molds 24 and the lower mold 23 are all set in the support groove 211; the two sides of the support groove 211 are first inclined surfaces 212; the upper outer side of the side mold 24 is provided with a second inclined surface 241, the lower outer side of the side mold 24 is provided with a third inclined surface 242, and the lower inner side of the side mold 24 is provided with a fourth inclined surface 243; the lower mold 23 is provided with fifth inclined surfaces 231 on both sides; the lower sides of the upper mold 22 are provided with fifth inclined surfaces 231 on both sides. A sixth inclined surface 221 is provided; the first inclined surface 212 corresponds to the third inclined surface 242, the fourth inclined surface 243 corresponds to the fifth inclined surface 231, and the second inclined surface 241 corresponds to the sixth inclined surface 221; and the first inclined surface 212, the second inclined surface 241, the third inclined surface 242, the fourth inclined surface 243, the fifth inclined surface 231 and the sixth inclined surface 221 all face the axis of the core mold 10; multiple first mounting holes 222 are provided on both sides of the upper mold 22, and each first mounting hole 222 is arranged sequentially along the length direction of the upper mold 22. A second mounting hole 213 is provided on the base 21 corresponding to the position of each first mounting hole 222, and a clamping bolt 25 is connected in each first mounting hole 222 and the corresponding second mounting hole 213.

[0045] The outer mold 20 is composed of a base 21, an upper mold 22, a lower mold 23, and two side molds 24. After the core mold 10 is laid, the loose fabric layers result in an excessively large size, making it difficult to install. To address this, each mold is fitted with a corresponding inclined surface. The spacing between the two side molds 24 is adjustable to accommodate the dimensions of the laid-out core mold 10. The upper mold 22 is then pressed down using clamping bolts 25. During this pressing process, the inclined surfaces allow the upper mold 22, side molds 24, and lower mold 23 to come close together and fit snugly. This ensures the external dimensions of the launch tube component are formed; all inclined surfaces are oriented towards the axis of the core mold 10, allowing for automatic inward contraction when the clamping bolts 25 are tightened; thus ensuring the dimensional accuracy of the launch tube component; during manufacturing, the layered material is first laid on the core mold 10, and then each part of the outer mold 20 is wrapped around it. After manufacturing is completed, the launch tube component and the core mold 10 can be left by removing each part of the outer mold 20 one by one, and then the core mold 10 can be pulled out of the launch tube component. The demolding operation is simple and convenient.

[0046] Specifically, the material launcher manufacturing device of this embodiment includes two main parts: a molding die and a demolding device.

[0047] The following are the settings instructions for the core mold 10 in the molding die:

[0048] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 and Figure 3 As shown, the core mold 10 includes a core 11 and two end assemblies; an end assembly is provided at each end of the core 11; the end assembly includes a shaft head 15 and a positioning frame 12; the shaft head 15 is fixedly provided at the end of the core 11, and the positioning frame 12 is detachably fixed on the shaft head 15, and the positioning frame 12 blocks the end of the forming gap of the launch tube part. The positioning frame 12 in the end assembly can be detachably fixed to the shaft head 15. When it is necessary to install or replace the core mold 10, the positioning frame 12 can be easily removed or installed from the shaft head 15, improving operational flexibility. The positioning frame 12 in the end assembly seals the end of the launching tube part forming gap, playing a positioning and sealing role. The positioning frame 12 can ensure the accurate position of the core 11 during the launching tube part forming process, thereby ensuring the dimensional accuracy of the launching tube, such as length and diameter. The shaft head 15 is fixed to the end of the core 11, providing stable support for the positioning frame 12, so that the positioning frame 12 can be firmly sealed at the end of the forming gap, preventing positional displacement during composite material injection and curing, and further improving the accuracy of the forming dimensions.

[0049] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, a bearing 16 is provided on the shaft head 15. The bearing 16 provided on the shaft head 15 can enable the core mold 10 to rotate with the assistance of the bracket during the layering process, which facilitates the layering operation.

[0050] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, a grooved connecting plate 13 is fixedly connected to the end of the core 11, and one end of the shaft head 15 is fixedly mounted on the grooved connecting plate 13; at least one connecting block 14 is fixedly connected to the grooved connecting plate 13, and each connecting block 14 is detachably fixedly connected to the positioning frame 12. The positioning frame 12 is connected to the core 11 through the grooved connecting plate 13 and the connecting blocks 14, which makes its assembly and disassembly simple and convenient.

[0051] Specifically, the grooved connecting plate 13 has a mounting groove, the connecting block 14 is L-shaped, and mounting holes are provided at corresponding positions on the mounting groove, the positioning frame 12 and the connecting block 14.

[0052] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2As shown, a guide rail is also fixedly installed inside the positioning frame 12, and a guide rail positioning groove 111 is provided at a corresponding position on the outer wall of the core 11. The cooperation between the guide rail and the guide rail positioning groove 111 can ensure the correct position of the core mold 10.

[0053] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 As shown, the shaft head 15 is also provided with a connecting slot 151. The connecting slot 151 is provided to facilitate its connection and cooperation with the demolding device 30 to achieve demolding.

[0054] The following are the settings for the outer mold 20 in the molding die:

[0055] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 4 and Figure 5 As shown, the first inclined surface 212, the second inclined surface 241, the third inclined surface 242, the fourth inclined surface 243, the fifth inclined surface 231, and the sixth inclined surface 221 all form a 45° angle with the horizontal plane. Setting each inclined surface to 45° can achieve gapless movement between the molds during the molding process, avoiding edge pressing and fabric pressing during mold closing; when each inclined surface forms a 45° angle, adjacent parts can fit better together during assembly.

[0056] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 4 and Figure 5 As shown, multiple mold-removing grooves 214 are provided on the base 21 outside each side mold 24, and the mold-removing grooves 214 are arranged sequentially along the length of the base 21. A mold-removing module 26 is provided in the mold-removing groove 214. The upper end of the mold-removing module 26 abuts against part of the lower end of the side mold 24. The mold-removing module 26 is provided with a through threaded hole, and a set screw 261 is threaded into the through threaded hole. One end of the set screw 261 abuts against the base 21. The mold-removing groove 214 has a mold-removing inclined surface 215. In the vertical direction, the end of the mold-removing inclined surface 215 away from the side mold 24 is higher than the end of the mold-removing inclined surface 215 near the side mold 24. By rotating the set screw 261, the mold-removing module 26 can drive the corresponding side mold 24 to move together along the mold-removing inclined surface 215. The lifting module 26, in conjunction with the lifting groove 214, can slide upward along the lifting slope 215 by rotating the set screw 261 and based on the contact between the end of the set screw 261 and the base 21. This causes the side molds 24 to move upward and outward along the direction edge of the lifting slope 215, thereby increasing the distance between the two side molds 24. This makes it easier to insert the core mold 10 into the outer mold 20 after the core mold is laid out, and also makes it easier to demold the outer mold 20 after the launch tube component is manufactured.

[0057] The following are the specifications for the demolding device 30:

[0058] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 6 and Figure 7 As shown, it also includes a demolding device 30, which includes a base 31 and a puller; the base 31 has a receiving channel for placing the core mold 10 with the launch tube component; the puller includes two hydraulic connecting rods 32, each hydraulic connecting rod 32 is respectively disposed on the outer sides of the receiving channel, and the output ends of the two hydraulic connecting rods 32 are connected to a connector 33, and the connector 33 is provided with a locking part for connecting the slot 151; a blocking bracket 34 is fixedly disposed at one end of the receiving channel near the connector 33, and the blocking bracket 34 abuts against the side of the positioning frame 12 on that side of the core mold 10 away from the core mold 10. The demolding device 30 uses a hydraulic connecting rod 32 as a power source. The hydraulic system can provide a strong and stable pulling force. During the demolding process, the two hydraulic connecting rods 32 can apply force simultaneously to achieve efficient demolding. The hydraulic system can achieve precise force control and stroke adjustment. During the demolding process, the output force and stroke of the hydraulic connecting rod 32 can be adjusted according to different part requirements and demolding difficulty to ensure a smooth and safe demolding process and avoid damage to the part.

[0059] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 6 As shown, an opening is provided on the top of the base 31, allowing the core mold 10 with the launch tube component to be placed into the receiving channel through the opening. The opening facilitates the placement of the core mold 10 with the launch tube component into the receiving channel and allows for direct observation of the component during the demolding process, ensuring the stability of the component during demolding.

[0060] Specifically, such as Figure 6 and Figure 7 As shown, the base 31 consists of two parallel side plates, and each hydraulic connecting rod 32 is respectively set on the outer side of the side plate; the lower ends of the two side plates are fixedly connected together by multiple rolling rollers, and support plates are fixedly connected to the front and rear ends of the two side plates. A blocking bracket 34 is fixedly set on the support plate near the connector 33. The blocking bracket 34 is U-shaped and can limit the position of the positioning frame 12 on that side when the hydraulic connecting rod 32 drives the connector 33 to extend.

[0061] Regarding other relevant explanations:

[0062] Specifically, since the launching tube component molding uses a medium-temperature curing system, at around 60℃, due to the thermal expansion and contraction of the material, the mold size does not equal the component size. After curing at the highest temperature and before cooling, the connecting block 14 and positioning frame 12 of the core mold 10 must be loosened to allow the component to shrink smoothly, ensuring that the shrinkage of the outer mold 20 does not affect the integrity of the component. During the cooling process, the core mold 10 plays a role in heat preservation and cooling down to the demolding temperature. The core mold 10 with the component is then transferred to the demolding device 30 for removal.

[0063] Specifically, the process is as follows: After assembling all parts of the core mold 10, the bearings 16 at both ends of the core mold 10 are placed on a bracket at the end. Supported by the bracket, the core mold 10 can be rotated, facilitating the layering operation and thus enabling the layering of the part. After the layering is completed, if the fabric is too loose and the size is too large to fit, the lifting screws 261 are rotated to raise each lifting module 26 along the corresponding side mold 24 at a 45° angle, increasing the distance between the two side molds 24, i.e., enlarging the inner cavity size of the outer mold 20, which facilitates the insertion of the core mold 10 after the layering is completed. After insertion, the mold is clamped in place using the clamping bolts 25, and then the entire mold is heated.

[0064] After medium-temperature curing, the connecting blocks 14 and positioning frames 12 at both ends of the core mold 10 need to be loosened before cooling to allow the core mold 10 to shrink smoothly and ensure that the shrinkage of the outer mold 20 does not affect the integrity of the part. After cooling, the core mold 10 with the part is rotated to... Figure 5 and Figure 6 On the demolding device 30, the connecting slot 151 on the shaft head 15 at one end of the core mold 10 is connected to the engaging part on the connector 33 of the demolding device 30. After the connection is completed, the hydraulic pump that controls the extension and retraction of the hydraulic connecting rod 32 is started to smoothly remove the launch tube component.

[0065] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
