[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 This utility model provides a technical solution: a sealing strip extrusion mold, including a sealing strip extrusion mold body 1, a discharge pipe 2 is provided at the discharge end of the sealing strip extrusion mold body 1, and a die 3 is provided at the end of the discharge pipe 2 through a quick disassembly and installation mechanism.

[0025] The quick-release and installation mechanism includes a drive ring 4. The drive ring 4 is threaded onto the outer side of the discharge pipe 2, ensuring that it can move left and right on the discharge pipe 2 when rotating. An annular inner cavity 5 is formed inside the drive ring 4, and an annular through groove 6 is formed on the inner side of the drive ring 4. A coarse movable column 7 is slidably arranged inside the annular inner cavity 5. A fine movable column 8 is fixed at the center of the end of the coarse movable column 7. The end of the fine movable column 8 passes through the interior of the annular through groove 6 and is fixedly connected to one side of the intermediate ring 9, allowing relative rotation between the annular inner cavity 5 and the coarse movable column 7. The annular groove 6 and the thin movable column 8 can rotate relative to each other. The intermediate ring 9 is slidably nested on the outside of the discharge pipe 2, so that the intermediate ring 9 can move on the left side of the discharge pipe 2. A fixed tie rod 10 is fixed on the other side of the intermediate ring 9 near the bottom of the die 3, and the inner side of the end of the fixed tie rod 10 is in contact with the end of the die 3. A movable tie rod 11 is provided on the top of the intermediate ring 9 through a rotating mechanism, and the inner side of the end of the movable tie rod 11 is in contact with the end of the die 3. An anti-rotation structure is provided between the outside of the discharge pipe 2 and the inside of the intermediate ring 9.

[0026] The rotating mechanism includes a groove 12. The top of the intermediate ring 9 has a groove 12, and a pin 13 is fixed inside the groove 12. The outer side of the pin 13 is rotatably connected to the inner side of the end of the movable pull rod 11, which ensures that the movable pull rod 11 can rotate around the pin 13, so that the movable pull rod 11 can be separated from the die 3, and the die 3 can be moved upward and disassembled.

[0027] The anti-rotation structure includes a limiting block 14. A limiting groove 15 is opened on the outer side of the discharge pipe 2, and the limiting block 14 is slidably installed inside the limiting groove 15. The outer side of the limiting block 14 is fixedly connected to the inner side of the intermediate ring 9. The limiting block 14 and the limiting groove 15 are symmetrically distributed about the central axis of the intermediate ring 9, which ensures that the limiting block 14 can slide inside the limiting groove 15, so that the intermediate ring 9 will not rotate.

[0028] A high-temperature resistant sealing ring 16 is fixed to the end of the discharge pipe 2, and the end of the high-temperature resistant sealing ring 16 fits into the end of the die 3, which improves the sealing performance at the connection between the die 3 and the discharge pipe 2.

[0029] There are six levers 17, and the levers 17 are distributed at equal angles about the central axis of the drive ring 4, so that the drive ring 4 can be easily rotated by levers 17.

[0030] There are six coarse movable columns 7 and six fine movable columns 8, and the coarse movable columns 7 and the fine movable columns 8 are distributed at equal angles about the central axis of the intermediate ring 9, which improves the balance of the driving ring 4 applying thrust or pull force to the intermediate ring 9.

[0031] There are two fixed tie rods 10, and the fixed tie rods 10 are designed with an "L" shape. The fixed tie rods 10 are symmetrically distributed about the central axis of the die 3. The design of the two fixed tie rods 10 can support the die 3, which facilitates the disassembly and installation of the die 3.

[0032] Working principle: When using this sealing strip extrusion mold, if it is necessary to change the die 3 with a different structure, turn the lever 17 by hand. At this time, the lever 17 drives the drive ring 4 to rotate. Since the drive ring 4 is threadedly connected to the discharge pipe 2, the drive ring 4 moves towards the die 3. The drive ring 4 simultaneously drives the annular inner cavity 5 and the annular through groove 6 to rotate relative to the coarse movable column 7 and the fine movable column 8. The drive ring 4 pushes the coarse movable column 7, the fine movable column 8, the intermediate ring 9, the limit block 14, the fixed pull rod 10 and the movable pull rod 11 to move simultaneously, so that the ends of the fixed pull rod 10 and the movable pull rod 11 are away from the die 3. Then, the movable pull rod 11 is rotated through the pin 13, so that the movable pull rod 11 is separated from the die 3. Finally, the die 3 is moved upward, and the die 3 can be quickly disassembled.

[0033] Place the replaced die 3 on the two fixed pull rods 10, and then rotate the movable pull rod 11 through the pin 13 so that the movable pull rod 11 contacts the die 3. Then, rotate the drive ring 4 in the opposite direction through the lever 17 so that the drive ring 4 moves away from the die 3. The drive ring 4 pulls the coarse movable column 7, the fine movable column 8, the intermediate ring 9, the fixed pull rod 10 and the movable pull rod 11 through the annular inner cavity 5 and the annular through groove 6 until the inner side of the end of the movable pull rod 11 and the fixed pull rod 10 is in close contact with the end of the die 3, thus completing the quick fixation of the die 3 after replacement. Since the threaded connection between the drive ring 4 and the discharge pipe 2 has self-locking properties, the die 3 is fixed.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
