[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 the present invention adopts an outer mold composed of a base, an upper mold, a lower mold and two side molds. After the upper layer of the core mold is laid, the cloth layer is loose and the size is too large to be conveniently installed. The molds are matched through corresponding inclined surfaces, and the spacing between the two side molds is adjustable to adapt to the outer dimensions of the layered core mold. The upper mold is then pressed down by a tightening bolt. During the pressing process, based on the corresponding inclined surface matching, the upper mold, side mold and lower mold can be close to each other to achieve a fit, thereby ensuring the external dimension molding effect of the launch tube component; each inclined surface is facing the axis of the core mold, which can automatically shrink inward when tightened by the tightening bolts; thereby ensuring the molding dimensional accuracy of the launch tube component; during manufacturing, the layered material is first laid on the core mold, and then the various parts of the outer mold are wrapped up. After the manufacturing is completed, the various parts of the outer mold can be removed one by one to leave the launch tube component and the core mold part, and then the core mold can be pulled out from the launch tube component. The demoulding operation is simple and convenient.

[0018] Furthermore, the demolding module cooperates with the demolding groove, and can slide upward along the demolding slope by rotating the top screw based on the abutment between the end of the top screw and the base, thereby driving the side molds to move upward and outward along the direction of the demolding slope, thereby increasing the distance between the two side molds, making it easier to install the core mold into the outer mold after paving is completed; and also making it easier to demold the outer mold after the launch tube product is completed.

[0019] Furthermore, each inclined surface is set to 45°, which can achieve gapless movement between the molds during the mold closing process and avoid edge and cloth pressing during the mold closing process; when each inclined surface is at an angle of 45°, the adjacent parts can fit better during the assembly process.

[0020] Furthermore, the positioning frame in the end assembly can be removably fixed on the shaft head. When the core mold needs to be installed or replaced, the positioning frame can be easily removed or installed from the shaft head, thereby improving the flexibility of operation; the positioning frame in the end assembly is sealed at the end of the molding gap of the launch tube component to play a positioning and sealing role. The positioning frame can ensure the accurate position of the core during the molding process of the launch tube component, thereby ensuring the dimensional accuracy of the launch tube, such as the length and diameter; the shaft head is fixed to the end of the core to provide stable support for the positioning frame, so that the positioning frame can be firmly sealed at the end of the molding gap to prevent positional deviation during the injection and curing of the composite material, thereby further improving the accuracy of the molding size.

[0021] Furthermore, the bearing provided on the shaft head can satisfy the requirement that the support assists in realizing the rotation of the core mold when the core mold is laid, thereby facilitating the layer laying operation.

[0022] Furthermore, the positioning frame is connected to the core through the grooved connecting plate and the connecting block, and its assembly and disassembly is simple and convenient.

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

[0024] Furthermore, the setting of the connecting slot facilitates its connection with the demoulding device to achieve demoulding.

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

[0026] Furthermore, the opening arrangement facilitates the more convenient placement of the core mold with the launch tube workpiece in the accommodating channel, and facilitates intuitive observation of the workpiece during the demoulding process of the core mold, thereby ensuring the stability of the workpiece during the demoulding process.

[0057] Among them, the relevant setting description of the demoulding device 30 is as follows:

[0058] Among the optional solutions of this embodiment, it is more preferred that Figure 6 and Figure 7 As shown, it also includes a demoulding device 30, which includes a base 31 and a puller; the base 31 has a accommodating channel, and the accommodating channel is used to place the core mold 10 with the launching tube part; the puller includes two hydraulic connecting rods 32, and each hydraulic connecting rod 32 is respectively arranged on both sides of the outside of the accommodating channel, and the output ends of the two hydraulic connecting rods 32 are connected to a connecting member 33, and the connecting member 33 is provided with a clamping portion for connecting to the card slot 151; a blocking bracket 34 is fixedly provided at one end of the accommodating channel close to the connecting member 33, and the blocking bracket 34 abuts against the side of the positioning frame 12 on this side of the core mold 10 away from the core mold 10. The demoulding device 30 uses a hydraulic connecting rod 32 as a power source. The hydraulic system can provide strong and stable pulling force.

During the demoulding process, the output force and stroke of the hydraulic connecting rod 32 can be adjusted according to different workpiece requirements and demoulding difficulty to ensure that the demoulding process is smooth and safe and avoid damage to the workpiece.

[0059] Among the optional solutions of this embodiment, it is more preferred that Figure 6 As shown, an opening is provided above the base 31, through which the core mold 10 with the launch tube product can be placed into the accommodating channel.

[0061] Among them, regarding other related instructions:

[0062] Specifically, since the launch tube molding adopts a medium-temperature curing system, when the temperature rises (around 60°C), the thermal expansion and contraction of the material causes the mold size to be unequal to the part 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 part to shrink smoothly and ensure that the shrinkage of the outer mold 20 does not affect the integrity of the part. During the cooling process, the core mold 10 is kept warm and cooled to the demolding temperature. The core mold 10 with the part is then transferred to the demolding device 30 for removal.

[0063] Specifically, the detailed description is as follows: after the various parts of the core mold 10 are assembled, the bearings 16 at both ends of the core mold 10 are respectively placed on a bracket at the end, and supported by the bracket, the core mold 10 can be rotated, which is convenient for the layer laying operation, thereby carrying out the layer laying of the workpiece; after the layer laying is completed, the cloth layer is loose and the size is too large to be loaded, so it is necessary to first rotate the top screws 261 to make each lifting module 26 and the corresponding side mold 24 rise in the 45° direction, so that the distance between the two side molds 24 becomes larger, that is, the inner cavity size of the outer mold 20 is enlarged, so as to facilitate the loading of the core mold 10 after the laying is completed; after putting it in, it is clamped in place with the tightening bolts 25, and the entire mold is heated.

[0064] After the medium temperature solidification, the connecting blocks 14 and the positioning frame 12 at both ends of the core mold 10 need to be loosened before cooling, so that the core mold 10 can shrink smoothly and ensure that the shrinkage of the outer mold 20 does not affect the integrity of the workpiece. After cooling, the core mold 10 with the workpiece is turned to Figure 5 and Figure 6 the connecting slot 151 on the shaft head 15 at one end of the core mold 10 cooperates with the engaging portion on the connector 33 of the demoulding device 30 to be connected together. After the connection is completed, the hydraulic pump that controls the extension of the hydraulic connecting rod 32 is started to smoothly remove the launch tube parts.

[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.
