Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a production mold for a vertical tail fin tip. The production mold for the vertical tail fin tip includes a main component 1, including an upper mold 11. A lower mold 12 is provided at the bottom of the upper mold 11. There are four upper molds 11 and four lower molds 12, which correspond one-to-one. The four upper molds 11 constitute the upper mold assembly, and the four lower molds 12 constitute the lower mold assembly, thus forming the entire vertical tail fin tip production mold. The mold can be connected to the base by ordinary bolts. The base is provided with forklift holes and lifting lugs, so as to facilitate the movement of the entire mold.

[0028] The upper mold 11 and the lower mold 12 are provided with placement grooves 13. Autoclave molding is a molding process that uses an autoclave to provide a high temperature and high pressure environment, so that the prepreg is heated, melted, flowed and solidified on the mold, and finally formed a high-precision and high-strength composite material component. First, the prepreg is laid on the inner surface of the placement groove 13, and the vertical tail fin tip cover is placed in the placement groove 13. Then, the mold and the vertical tail fin tip cover are put into the autoclave as a whole. After that, the excess part is cut off, thereby completing the production of the vertical tail fin tip cover. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0029] The upper mold 11 and the lower mold 12 are modularly designed, allowing for assembly. If a part is damaged, it can be partially replaced and repaired to avoid scrapping the whole thing, thereby reducing production costs.

[0030] Mounting component 2, located inside the upper mold 11, includes mounting component 21. Mounting component 21 is used to assemble the upper mold 11 and the lower mold 12 respectively. Mounting component 21 includes a locking block 211 fixed on the upper mold 11. The upper mold 11 has a locking groove 11-1 corresponding to the locking block 211. The locking block 211 can engage with the locking groove 11-1. Adjacent upper molds 11 can be spliced ​​together through the cooperation of the locking block 211 and the locking groove 11-1.

[0031] A rectangular groove 11-2 is provided in the upper mold 11. A locking block 212 is slidably disposed in the rectangular groove 11-2. A locking groove 211-1 is provided on the locking block 211. The locking groove 211-1 is slightly larger than the locking block 212. The locking block 212 can engage with the locking groove 211-1. When the locking block 212 slides down in the rectangular groove 11-2 and engages with the locking groove 211-1, the relative position of the locking block 211 and the locking groove 11-1 will be locked, thereby completing the assembly of the entire upper mold 11.

[0032] The lower mold 12 is also equipped with a locking block 211 and a locking slot 11-1. Through the cooperation of the two, the overall assembly of the four lower molds 12 can be completed.

[0033] Example 2 Reference Figures 3-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the mounting component 2 also includes a locking element 22 located on one side of the locking block 212. The locking element 22 is designed to increase the overall tightness of the upper mold 11 connection and lock the relative positions of each module.

[0035] The locking component 22 includes a fixing seat 221 fixed to one side of the locking block 212. A rubber pad 222 is fixed to the bottom of the fixing seat 221. The rubber pad 222 has a hole corresponding to the locking block 212. The movement of the fixing seat 221 can synchronously drive the rubber pad 222 and the locking block 212 to move.

[0036] Specifically, the upper mold 11 has a first threaded hole 11-3, and a first bolt 223 is internally threaded into the first threaded hole 11-3. The number of first threaded holes 11-3 is the same as that of the locking block 212. The first bolt 223 is used to push the locking block 212 into the locking groove 211-1 and lock the position of the locking block 212, thereby preventing the locking block 211 and the locking groove 11-1 from separating, thus ensuring the stability of the upper mold 11 splicing.

[0037] Specifically, the fixed base 221 can slide in the first threaded hole 11-3, the rectangular groove 11-2 and the first threaded hole 11-3 are connected to each other, and the size of the first threaded hole 11-3 is larger than the size of the rectangular groove 11-2.

[0038] Before the upper mold 11 is assembled, the locking block 212 is not located in the rectangular groove 11-2. After the locking block 211 engages with the groove 11-1, the fixed seat 221 is moved to insert the locking block 212 into the rectangular groove 11-2. At this time, the rubber pad 222 will be in contact with the end face of the bottom of the first threaded hole 11-3, so that the locking block 212 and the fixed seat 221 are at a certain height. Then the first bolt 223 is threadedly connected to the first threaded hole 11-3. As the first bolt 223 is tightened, the first bolt 223 will push the fixed seat 221 to move downward, so that the rubber pad 222 is compressed, and at the same time, the locking block 212 will be driven to move closer to the locking groove 211-1.

[0039] Specifically, one end of the locking block 212 is inclined, and the locking groove 211-1 is correspondingly inclined. By setting the inclined shape, when the locking block 212 moves downward, the inclined surface of the locking block 212 will apply a pushing force to the inclined surface of the locking groove 211-1, so that the locking block 211 and the locking groove 11-1 are more tightly engaged, so that the two adjacent upper molds 11 are more tightly fitted and maintain a tight fit.

[0040] When installing the locking block 212, the bevel direction of the locking block 212 must be parallel to the bevel of the locking groove 211-1.

[0041] When it is necessary to replace a single upper mold 11, rotate the first bolt 223 in the reverse direction to separate the first bolt 223 from the first threaded hole 11-3. Then, invert the upper mold 11 to separate the fixing seat 221 and the locking block 212 from the upper mold 11 at the first threaded hole 11-3, thereby releasing the limiting position of the locking block 211 and the locking groove 11-1, so that the adjacent upper mold 11 can be separated.

[0042] Example 3 Reference Figures 3-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, the upper mold 11 is provided with nine sets of locking blocks 212 and locking grooves 211-1. There are four upper molds 11, which together form the upper mold as a whole. Two adjacent upper molds 11 are assembled by a set of locking blocks 211 and locking grooves 11-1, and with the cooperation of three sets of locking blocks 212 and locking grooves 211-1.

[0044] The lower mold 12 also has the same number of locking blocks 212 and locking slots 211-1. The assembly method of the lower mold 12 is the same as that of the upper mold 11.

[0045] Specifically, the upper mold 11 is composed of a first wedge 111, a second wedge 112, a third wedge 113, and a fourth wedge 114. The first wedge 111 has only a slot 11-1 and no fixed block 211. The fourth wedge 114 has only a fixed block 211 and no slot 11-1. The second wedge 112 and the third wedge 113 have both a block 211 and a slot 11-1.

[0046] When assembling the upper integral mold, the locking block 211 on the second wedge 112 is inserted into the locking groove 11-1 of the first wedge 111, the locking block 211 on the third wedge 113 is inserted into the locking groove 11-1 of the second wedge 112, and the locking block 211 on the fourth wedge 114 is inserted into the locking groove 11-1 of the third wedge 113. They are assembled in sequence and locked by multiple first bolts 223.

[0047] Specifically, four positioning posts 14 are fixed on the lower mold 12. The upper mold 11 has a small through groove 11-4. The positioning posts 14 are inserted into the small through groove 11-4. The positioning posts 14 and the small through groove 11-4 are coaxial. There are four of each, and they correspond one to one. When installing the overall mold, the four upper molds 11 and the lower mold 12 need to be assembled first to form a complete upper and lower mold. Then, the vertical tail wingtip cover is placed in the placement groove 13 of the lower mold 12. Then, the upper and lower molds are assembled to complete the overall assembly. Through the cooperation of the positioning posts 14 and the small through groove 11-4, the upper and lower molds can be positioned during assembly to ensure that the upper and lower molds are coaxial during installation.

[0048] Specifically, the lower mold 12 has a second threaded groove 12-1, and the upper mold 11 has a large through groove 11-5. The second threaded groove 12-1 is internally threaded with a second bolt 15. There are four second bolts 15. The number of the second threaded groove 12-1 and the large through groove 11-5 are the same and correspond one-to-one. The second bolts 15 are inserted into the large through groove 11-5. When installing the overall mold, after the upper and lower molds are coaxially positioned, the second bolts 15 are inserted from the large through groove 11-5 into the upper mold 11 and into the second threaded groove 12-1. The second bolts 15 are threadedly connected to the second threaded groove 12-1, thereby fixing the upper and lower molds to form an overall mold.

[0049] Specifically, four lifting rings 16 are fixed on the upper mold 11 and the lower mold 12. The lifting rings 16 facilitate hoisting and move the entire production mold to the designated position for subsequent autoclave molding operations.

[0050] During use, when assembling the upper integral mold, the locking block 211 on the second wedge 112 is inserted into the slot 11-1 of the first wedge 111. After the locking block 211 engages with the slot 11-1, the fixed base 221 is moved to insert the locking block 212 into the rectangular slot 11-2. At this time, the rubber pad 222 will be in contact with the bottom end face of the first threaded hole 11-3, so that the locking block 212 and the fixed base 221 are at a certain height. Then, the first bolt 223 is threaded into the first threaded hole 11-3. As the first bolt 223 is tightened, it will push the fixed base 221 downward. This compresses the rubber pad 222, causing the locking block 212 to move downwards. The inclined surface of the locking block 212 will exert a pushing force on the inclined surface of the locking groove 211-1, thereby making the locking block 211 and the locking groove 11-1 more tightly engaged, making the first wedge 111 and the second wedge 112 more tightly fitted and maintaining a tight fit, thus completing the splicing of the two. Then, the operation is repeated to complete the assembly of the third wedge 113 and the fourth wedge 114 in sequence, forming an upper mold as a whole. Then, the operation is repeated to complete the assembly of the four lower molds 12, forming a complete lower mold. Then, the prepreg is laid on the inner surface of the placement groove 13.

[0051] Next, the vertical tail fin tip is placed in the placement slot 13 of the lower mold 12. Then, the upper mold assembly consisting of four upper molds 11 is moved so that the positioning pin 14 is inserted into the small through slot 11-4. At this time, it is ensured that the upper and lower molds are coaxial during installation. Finally, the second bolt 15 is inserted into the upper mold 11 from the large through slot 11-5 and enters the second threaded slot 12-1. The second bolt 15 is threadedly connected to the second threaded slot 12-1, which can fix the upper and lower molds, thereby forming an integral mold. The integral production mold is moved to the designated position using hoisting equipment, so as to carry out the subsequent autoclave molding operation.

[0052] When it is necessary to replace a single upper mold 11 or lower mold 12, rotate the first bolt 223 in the reverse direction to separate the first bolt 223 from the first threaded hole 11-3. Then, invert the upper mold 11 to separate the fixing seat 221 and locking block 212 from the upper mold 11 at the first threaded hole 11-3, thereby releasing the limiting of the locking block 211 and the locking groove 11-1. This allows the adjacent upper mold 11 or lower mold 12 to be separated, and then a new module can be installed. The mold does not need to be scrapped as a whole, thereby reducing production costs.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
