Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0017] See also Figure 1 and Figure 2 , is the first embodiment of the utility model, which provides a technical solution: a profile extrusion die, including an outer die body 1 and an inner die body 2, the outer die body 1 is provided with an installation groove 12 for inserting and installing the inner die body 2, the front end surface of the inner die body 2 is penetrated with a profile extrusion port 21, a card-mounted connection structure is provided between the inner die body 2 and the outer die body 1, the card-mounted connection structure includes an annular dial seat 31, an annular retaining ring 32, a T-shaped plug block 33 and an annular card groove 22, the rear end surface of the inner die body 2 is provided with an annular card groove 22 corresponding to the T-shaped plug block 33, the surface of the outer die body 1 The surface is penetrated with a socket 11 corresponding to the T-shaped plug block 33, and the inner end of the T-shaped plug block 33 passes through the socket 11 to the annular groove 22, which can stably limit the inner mold body 2 and realize the quick connection between the inner mold body 2 and the outer mold body 1. The annular dial seat 31 is slidably sleeved on the surface of the outer mold body 1, and the top surface of the annular dial seat 31 is fixed with an annular retaining ring 32. The annular retaining ring 32 covers the outer ends of the two T-shaped plug blocks 33 on the inner side, which can play a stable blocking and limiting role on the T-shaped plug block 33, ensuring the limiting stability of the T-shaped plug block 33 on the inner mold body 2, and the card-mounted connection structure The structure also includes a side slide groove 34, a spring 35 and a side slider 36. Two side slide grooves 34 are symmetrically provided on the surface of the outer mold body 1. A side slider 36 is movably installed in the side slide groove 34 through the spring 35. One end of the side slider 36 extends to the surface of the outer mold body 1 and is fixedly connected to the inner wall of the annular dial seat 31. Under the pushing action of the spring 35, the side slider 36 will always be against the inner wall of one end of the side slide groove 34 during daily use, and the position stability of the annular retaining ring 32 and the annular dial seat 31 is ensured, thereby ensuring the limiting stability of the annular retaining ring 32 on the T-shaped plug 33, thereby ensuring the inner mold The inner mold body 2 and the outer mold body 1 are connected to each other to ensure stability. If the inner mold body 2 is to be removed for replacement later, the annular shift seat 31 only needs to be pushed down forcefully, so that the side slider 36 moves down to compress the spring 35, causing the annular retaining ring 32 to move down with the annular shift seat 31 until the annular retaining ring 32 moves down to the bottom of the T-shaped plug block 33. At this time, the annular retaining ring 32 no longer causes any obstruction to the T-shaped plug block 33, and the operator can pull out the T-shaped plug block 33, thereby releasing the limit on the inner mold body 2, and the inner mold body 2 can be directly pulled out from the mounting groove 12, completing the quick disassembly and replacement of the inner mold body 2.

[0018] A guide rod 37 is fixed in the side slide groove 34 , and the side slider 36 and the spring 35 are movably mounted on the guide rod 37 . The guide rod 37 can guide the side slider 36 and prevent the spring 35 from falling off.

[0019] The surface of the annular shifting seat 31 is provided with an annular shifting groove, which is convenient for subsequent operators to shift the annular shifting seat 31 with fingers.

[0020] Among them, the rear end of the inner mold body 2 penetrates through the rear surface of the outer mold body 1 for subsequent connection to an external extrusion pipeline. Embodiment

[0021] Please refer to Figures 1 to 3 , which is the second embodiment of the present utility model. Based on the previous embodiment, the difference is that through the provided annular rubber ring 4 and positioning protrusions 41, it plays an auxiliary positioning role in the initial stage of installing the inner mold body 2, further improving the assembly convenience between the inner mold body 2 and the outer mold body 1.

[0022] Specifically, an annular rubber ring 4 is also embedded and installed on the front end surface of the outer mold body 1. The annular rubber ring 4 is in contact with the front end of the inner mold body 2. A plurality of integral positioning protrusions 41 are provided on the inner wall of the annular rubber ring 4. Both of them are made of fluororubber material and will undergo elastic deformation when being squeezed. Positioning slots 23 corresponding to the positioning protrusions 41 are provided on the surface of the inner mold body 2. The positioning protrusions 41 are embedded into the positioning slots 23. In the initial stage of installing the inner mold body 2, when the inner mold body 2 is completely pushed into the installation groove 12, the positioning protrusions 41 will also be squeezed into the positioning slots 23, thereby playing a certain auxiliary limiting role on the inner mold body 2, facilitating subsequent operators to further limit the inner mold body 2 by using the T-shaped insertion block 33, and further improving the assembly convenience between the inner mold body 2 and the outer mold body 1.

[0023] Among them, a rectangular cavity is provided inside the annular rubber ring 4, and the position of the rectangular cavity corresponds to the positioning protrusions 41, so that the positioning protrusions 41 have sufficient deformation space when being squeezed subsequently.
