DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 3, which is the first embodiment of the utility model, and this embodiment provides a technical solution: a diverter die structure of an extrusion die, comprising a diverter die annular seat body 1 and a die core 2, an integrated core platform 21 is provided at the center of the die core 2, and a feed hole 22 is provided through the core platform 21, four diverter holes 23 are provided on the surface of the die core 2, and the four diverter holes 23 surround the core platform 21, an integrated annular platform 24 is provided at the edge of the die core 2, the inner diameter of the diverter die annular seat body 1 is consistent with the outer diameter of the die core 2, an annular platform 11 corresponding to the annular platform 24 is provided on the inner wall of one end of the diverter die annular seat body 1, two strip positioning blocks 25 are symmetrically welded on the circumferential surface of the die core 2, and the inner wall of the diverter die annular seat body 1 is provided with two strip positioning blocks 25 corresponding to the strip positioning blocks The strip positioning groove 12 corresponds to the positioning block 25, and the strip positioning groove 12 is communicated with the annular mounting groove 11. The mold core 2 is inserted into the inner side of the annular seat body 1 of the diverter mold, and the annular mounting platform 24 is inserted into the inner side of the annular mounting groove 11. The strip positioning block 25 slides into the inner side of the strip positioning groove 12. The action of the strip positioning block 25 and the strip positioning groove 12 prevents the mold core 2 from rotating on the inner side of the annular seat body 1 of the diverter mold, and plays a positioning role. A disassembly structure 3 is also provided between the annular seat body 1 of the diverter mold and the annular mounting platform 24. The disassembly structure 3 includes two movable plates 31 movably installed on the outer surface of the annular seat body 1 of the diverter mold. A limiting rod 32 is welded and fixed on one side of the movable plate 31. A limiting slot 3 corresponding to the limiting rod 32 is provided on the surface of the annular mounting platform 24. 3, the end of the limiting rod 32 passes through the limiting slot 33, which can effectively limit the annular platform 24 to ensure the connection stability between the mold core 2 and the annular seat body 1 of the diverter mold. The disassembly and assembly structure 3 also includes an inner slide groove 34 opened inside the annular seat body 1 of the diverter mold, and an inner slide block 35 and an inner slide rod 36 are arranged in the inner slide groove 34. The inner slide block 35 is slidably located in the inner slide groove 34, and an inner slide rod 36 is fixed to one side of the inner slide block 35. The end of the inner slide rod 36 passes through the outer surface of the annular seat body 1 of the diverter mold and is fixed to the movable plate 31, so that the movable plate 31 can slide smoothly on the outer surface of the annular seat body 1 of the diverter mold. The disassembly and assembly structure 3 also includes a limiting pressure plate 37, a fastening bolt 38 and a cylindrical end seat 39. The cylindrical end seat 39 is fastened by the fastening bolt 3 8 is fixed on the outer surface of the annular seat body 1 of the diverter mold, and the surface of the cylindrical end seat 39 is welded and fixed with a limiting pressure plate 37, and the end of the limiting pressure plate 37 extends to the surface of the movable plate 31 to press the movable plate 31, which can effectively press and fix the movable plate 31, and ensure that the limiting rod 32 can be stably inserted into the limiting slot 33 during daily use, and ensure the installation stability of the mold core 2. If the mold core 2 is to be removed for replacement in the later stage, it is only necessary to loosen the fastening bolt 38 by rotating it counterclockwise to release the fixation of the cylindrical end seat 39 and the limiting pressure plate 37. At this time, the cylindrical end seat 39 is rotated so that the limiting pressure plate 37 is rotated and removed from the surface of the movable plate 31, so that it will no longer cause any obstruction to the movable plate 31, and then the movable plate 31 is pulled,The inner slide bar 36 slides with the inner slide block 35, and the end of the limiting rod 32 can be pulled out from the limiting slot 33, releasing the limit of the annular platform 24. At this time, the mold core 2 can be directly separated from the annular seat body 1 of the diverter mold, and the annular platform 24 can be moved out of the annular groove 11, and the strip positioning block 25 can be slid out of the strip positioning groove 12, so as to realize the rapid disassembly and assembly operation of the mold core 2, and facilitate the subsequent disassembly and replacement of the mold core 2.

[0019] There are two thread grooves on the outer surface of the annular seat body 1 of the splitter die, and the thread grooves correspond to the fastening bolts 38 so that the threaded ends of the fastening bolts 38 can be screwed in smoothly.

[0020] The outer surface of the annular seat body 1 of the manifold is also provided with a through hole corresponding to the limiting rod 32 , and the through hole is communicated with the annular groove 11 , so that the limiting rod 32 can pass through smoothly.

[0021] Example 2

[0022] See also Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the positioning structure can be set to play a certain auxiliary positioning role for the mold core 2 when the mold core 2 and the diverter mold annular seat body 1 are assembled, thereby further improving the assembly convenience of the mold core 2 and the diverter mold annular seat body 1.

[0023] Specifically, it also includes a positioning structure, which is arranged between the strip positioning groove 12 and the strip positioning block 25. The positioning structure includes a rubber seat 121 embedded in the inner wall of the strip positioning groove 12. The surface of the rubber seat 121 is provided with an integrated positioning rubber block 122. Both are made of rubber material and will undergo elastic deformation when squeezed. The surface of the strip positioning block 25 is provided with a positioning groove 251 corresponding to the positioning rubber block 122. The positioning rubber block 122 is embedded in the positioning groove 251. When the strip positioning block 25 slides during the installation of the mold core 2, the positioning rubber block 122 is inserted into the positioning groove 251. When the strip positioning groove 12 is inserted into the inner side, the positioning rubber block 122 will be squeezed and deformed until the strip positioning block 25 slides to the bottom end of the strip positioning groove 12. At this time, the positioning rubber block 122 will rebound under its own elasticity and be stuck in the positioning slot 251, thereby producing a certain auxiliary limiting effect on the strip positioning block 25, ensuring that the mold core 2 will not easily slide out from the inner side of the diverter mold annular seat body 1 at this time, making it convenient for subsequent operators to limit the annular platform 24 through the limiting rod 32, thereby further improving the assembly convenience of the mold core 2 and the diverter mold annular seat body 1.

[0024] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
