Detailed Implementation

[0061] 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.

[0062] like Figures 1 to 6 As shown in the embodiments of this application, a method for injection molding tire repair is disclosed, including the following steps:

[0063] S100: Insert a drilling tool through the hole in tire 1 until the inner layer of tire 1 is penetrated;

[0064] S200: Determine the screw-in depth through the inner layer hole;

[0065] S300: The elastic umbrella-shaped film 6 is inserted into the tire 1 through the through hole in the middle of the drilling tool by the insertion needle 7. After the elastic umbrella-shaped film 6 enters the tire 1, it opens without external force. Pulling the pull wire 61 in the middle of the umbrella-shaped film 6 makes the edge of the umbrella-shaped film 6 adhere to the inner wall of the tire 1.

[0066] S400: Rubber repair agent 8 is injected into the middle of the drilling tool through the injection pipe 9, so that the rubber repair agent 8 fills the cavity inside the umbrella-shaped film 6 and the tire 1.

[0067] S500: After the drilling tool is withdrawn and the rubber repair agent 8 has completely solidified, the pull wire 61 is cut.

[0068] In this method, a hole is first drilled at the puncture site, and then an umbrella-shaped film 6 is inserted into the hole. The film forms a seal at the puncture site, meaning that after the film adheres to the inner wall of the tire, it together with the inner wall of the tire to form a rubber injection cavity. Next, rubber repair agent 8 is injected into the middle of the drilling tool, so that the repair agent fills the cavity between the umbrella-shaped film 6 and the inside of the tire 1. After a period of time, the rubber solidifies into a rubber component and perfectly bonds with the puncture site, thereby repairing the damaged area. This method is simple and convenient, and does not require drilling a large hole at the puncture site, thus reducing further damage to the tire 1.

[0069] In this embodiment, in step S300, the rubber repair agent 8 fills the cavity inside the umbrella-shaped film 6 and the tire 1, and at the same time fills the central through hole of the drilling tool.

[0070] In the above steps, the rubber repair agent 8 is simultaneously filled into the central through hole of the drilling tool. Due to the elasticity of the tire 1, when the drilling tool is withdrawn, the rubber repair agent 8 in the through hole of the drilling tool fills the crack after drilling, thereby enhancing the repair effect on the tire 1.

[0071] In this embodiment, the drilling tool is a hollow self-tapping screw.

[0072] Specifically, during drilling, the self-tapping screw body 2 is screwed into the tire 1 by turning the hollow self-tapping screw 2, thereby achieving the purpose of drilling. In this process, the hollow self-tapping screw is not only used as a drilling tool, but also as a channel for conveying the rubber repair agent 8.

[0073] Therefore, the design of the hollow self-tapping screw simplifies the operation steps and improves repair efficiency.

[0074] In this embodiment, the drilling tool includes a screw body 2, the surface of which is provided with a self-tapping thread 21, and a first through hole 22 extending through the middle of the screw body 2. It also includes an extension screw connected to the screw body 2. The lower end of the extension screw is a tapered structure 33. When the extension screw is inserted into the through hole, the upper end of the extension screw is threadedly connected to the upper end of the screw body 2, and the tapered structure 33 of the extension screw extends out of the first through hole 22 of the screw body 2.

[0075] Specifically, the screw body 2 is screwed into the puncture of the tire 1 until the tapered structure 33 at the lower end of the screw penetrates into the inner layer of the tire 1, thereby expanding the space of the entire puncture, so that the first through hole 22 can communicate with the inner space of the tire 1, so that the subsequent umbrella-shaped film 6 can enter the interior of the tire 1 through this channel.

[0076] In this structure, by providing a self-tapping thread 21 on the surface of the screw body 2, a tire repair channel can be screwed out from the puncture hole of the tire 1 by twisting. Moreover, the drilling of the tire 1 by twisting the self-tapping thread 21 causes less damage to the tire 1, ensuring the structural strength of the tire 1 and providing convenience for subsequent operations.

[0077] In a further design, the expansion screw and the screw body 2 are connected by threads. This connection method is simple, reliable, and easy to disassemble and assemble. Moreover, the tapered structure 33 of the expansion screw extends out of the first through hole 22 of the screw body 2, which can guide and enlarge the hole during drilling, making the drilling process smoother.

[0078] In this embodiment, the expansion screw includes a nut 31 and a guide spindle 32. The bottom of the guide spindle 32 is the tapered structure 33, and the guide spindle 32 is detachably connected to the nut 31.

[0079] Step S200 is as follows:

[0080] S210: Loosen the nut 31 and remove the guide spindle 32. Remove the guide spindle 32 and insert the right-angle end of the guide spindle into the first through hole 22. By rotating the self-tapping thread 21, ensure that the right-angle end of the guide spindle 32 has damping.

[0081] Specifically, after the drilling tool completes the drilling operation, the flat end of the disassembled guide mandrel 32 is inserted back into the first through hole 22. Since the innermost layer of the tire 1 has a metal mesh structure, after the tapered end is pierced and pulled out in the previous step, the metal mesh will retract and form a certain cluster due to the elasticity of the metal mesh. Therefore, by inserting the flat end of the guide mandrel 32, the clustered metal mesh in the inner layer of the tire 1 can be separated, so that the inner layer of the tire 1 presents a round hole, which facilitates the subsequent insertion of the umbrella-shaped film 6.

[0082] In addition, the expansion screw can also be an integral structure, and the conical end of the screw can be used to check whether the inner layer of the tire 1 is open. However, a better way is to disassemble the guide spindle 32 separately and use the flat end of the guide spindle 32 to check whether the inner layer of the tire 1 is open. Since the contact area of ​​the flat end is larger, it can provide a more intuitive judgment for the manual inspection in the inspection room.

[0083] In this embodiment, the expansion screw has a second through hole and a third through hole that are interconnected. The diameter of the second through hole is larger than that of the third through hole. A retaining ring 4 is provided in the second through hole, so that the guide spindle 32 passes through the retaining ring 4 and the third through hole in sequence. A notch 41 is provided on one side of the retaining ring 4. The expansion screw has a locking port on the side of the second through hole and also includes a locking bolt 5. The locking bolt 5 extends into the locking port and abuts against the retaining ring 4.

[0084] Specifically, when installing the guide spindle 32, the locking bolt 5 is in a loose state. The guide spindle 32 is passed through the clamping ring 4 and the third through hole in sequence. The guide spindle 32 is rotated so that the self-tapping thread 21 at the tapered structure 33 of the guide spindle 32 is in the same direction as the self-tapping thread 21 on the surface of the screw body 2. After the position is rotated into place, the locking bolt 5 is tightened. Here, the locking bolt 5 can be threaded to the locking port so that the locking bolt 5 abuts against the clamping ring 4. The clamping ring 4 clamps the guide spindle 32, that is, the clamping ring 4 fixes the guide spindle 32. When disassembling, the locking bolt 5 is loosened so that the guide spindle 32 can be taken out.

[0085] This structural design allows for easy and quick disassembly and reinstallation when the guide spindle 32 needs to be disassembled for inspection or replacement, improving the convenience and efficiency of operation.

[0086] In this embodiment, the umbrella-shaped film 6 includes a film layer, and an elastic structure is provided on the inner side of the film layer so that the film layer opens in an umbrella shape when no external force is applied and contracts in a contracted shape when an external force is applied. It also includes the pull wire 61, one end of which is connected to the middle of the film layer.

[0087] Specifically, after drilling is completed, the umbrella-shaped film 6 is first contracted by external force. Then, the contracted umbrella-shaped film 6 is inserted into the first through hole 22. The umbrella-shaped film 6 is then pushed into the tire 1 by the insertion needle 7. At this time, the external force disappears and the umbrella-shaped film 6 opens. Then, the pull wire 61 is pulled so that the edge of the umbrella-shaped film 6 adheres to the inner wall of the tire 1, thereby providing a cavity for the rubber repair agent 8 to be accommodated, thus achieving a good repair effect.

[0088] In this structure, the elastic umbrella-shaped film 6 and the pull line 61 work together to allow the edge of the umbrella-shaped film 6, which enters the interior of the tire 1, to be pulled by the pull line 61 so that the subsequent rubber repair agent 8 can solidify at the puncture site of the tire 1, thereby achieving targeted repair of the puncture site of the tire 1.

[0089] This utility model also discloses a tire repair tool, including a drilling tool and an umbrella-shaped film 6 for use together. The drilling tool includes a screw body 2, the surface of which is provided with a self-tapping thread 21. The middle part of the screw body 2 is provided with a first through hole 22 that runs vertically through it. It also includes an extension screw connected to the screw body 2. The lower end of the extension screw is a tapered structure 33. When the extension screw is inserted into the through hole, the upper end of the extension screw is threaded to the upper end of the screw body 2, and the tapered structure 33 of the extension screw extends out of the first through hole 22 of the screw body 2.

[0090] The umbrella-shaped film 6 includes a film layer with an elastic structure on the inner side of the film layer, so that the film layer opens in an umbrella shape when no external force is applied and contracts in a contracted shape when an external force is applied. It also includes the pull wire 61, one end of which is connected to the middle of the film layer.

[0091] In practice, the screw body 2 is screwed into the puncture hole of the tire 1 until the tapered structure 33 at the lower end of the screw penetrates into the inner layer of the tire 1, thereby expanding the space of the entire puncture hole so that the first through hole 22 can communicate with the inner space of the tire 1. After drilling is completed, the umbrella-shaped film 6 is first contracted by external force, and then the contracted umbrella-shaped film 6 is inserted into the first through hole 22. The umbrella-shaped film 6 is then pierced into the tire 1 by the insertion needle 7. At this time, the external force disappears and the umbrella-shaped film 6 opens. Then, the pull wire 61 is pulled so that the edge of the umbrella-shaped film 6 adheres to the inner wall of the tire 1. Then, the subsequent operation of injecting rubber repair agent 8 can be carried out. After the injection is completed, the drilling tool is withdrawn. After the rubber repair agent 8 has completely solidified, the pull wire 61 is cut.

[0092] Using the tools described above for tire repair makes the process simple and convenient, and eliminates the need to drill large holes in the puncture site, thus reducing the risk of further damage to the tire.

[0093] In addition, the expansion screw includes a nut 31 and a guide spindle 32, the bottom of which is the tapered structure 33, and the guide spindle 32 is detachably connected to the nut 31;

[0094] The expansion screw has a second through hole and a third through hole that are interconnected. The diameter of the second through hole is larger than that of the third through hole. A retaining ring 4 is provided in the second through hole, so that the guide spindle 32 passes through the retaining ring 4 and the third through hole in sequence. A notch 41 is provided on one side of the retaining ring 4. The expansion screw has a locking port on the side of the second through hole and also includes a locking bolt 5. The locking bolt 5 extends into the locking port and abuts against the retaining ring 4.

[0095] Specifically, when installing the guide spindle 32, the locking bolt 5 is in a loose state. The guide spindle 32 is passed through the clamping ring 4 and the third through hole in sequence. The guide spindle 32 is rotated so that the self-tapping thread 21 at the tapered structure 33 of the guide spindle 32 is in the same direction as the self-tapping thread 21 on the surface of the screw body 2. After the position is rotated into place, the locking bolt 5 is tightened. Here, the locking bolt 5 can be threaded to the locking port, so that the locking bolt 5 abuts against the clamping ring 4. The clamping ring 4 clamps the guide spindle 32, that is, the clamping ring 4 fixes the guide spindle 32. When disassembling, the locking bolt 5 is loosened, and the guide spindle 32 can be taken out. Then, the flat end of the disassembled guide spindle 32 is inserted back into the first through hole 22 to push aside the gathered metal wire mesh in the inner layer of the tire 1, so that the inner layer of the tire 1 presents a round hole shape, which facilitates the subsequent feeding of the umbrella-shaped film 6.
