[0002] In modern manufacturing, extruders, as an important forming equipment, are widely used in the processing of metals, plastics and other materials. The design and installation of the die play a vital role in the operation of the extruder, directly affecting the quality of the product and production efficiency.

[0003] However, the installation method of the die shaft and the die of the traditional extruder is usually to set a boss on the die and a countersunk hole corresponding to the boss. The die shaft is installed through the cooperation of the boss on the die and the countersunk hole on the die shaft. Since the edge of the countersunk hole is thin, the die shaft cannot push the rod when the aluminum rod is fed in. It is necessary to make a translation die frame and install a shaft for pushing the rod. During extrusion, the rod is pushed on and the rod is inserted, and then the die barrel is opened and the mold is mounted. Obviously, this installation method has the disadvantages of complex structure and high cost. Utility Model Content

[0024] See also Figures 1 to 3 As shown, an embodiment of the present application provides a quick installation structure for a die shaft and a die of an extruder, which includes a die shaft 10, a die 20, a disassembly component and at least one set of positioning components 30, wherein:

[0025] The end of the mold shaft 10 is provided with a boss 11, and the end surface of the mold 20 is provided with a groove 21, and the boss 11 is adapted to the groove 21;

[0026] The mold 20 is detachably fixed to one end of the mold shaft 10 by a detachable assembly, and the boss 11 is located in the groove 21;

[0027] Each set of positioning components 30 includes a positioning member 31 and a positioning groove 32. The positioning member 31 is detachably mounted on the outer wall of the mold shaft 10. The positioning groove 32 is provided on the mold 20. Each positioning member 31 corresponds to a positioning groove 32. The positioning member 31 and the positioning groove 32 cooperate to position the mold 20 and the mold shaft 10 when the mold 20 is mounted on the mold shaft 10.

[0028] The cooperation of the boss 11, the groove 21 and the positioning assembly 30 improves the positioning accuracy of the mold shaft 10 and the mold 20, which not only realizes the fast and accurate installation of the mold shaft 10 and the mold 20, but also has a simple structure and is easy to operate.

[0029] In one embodiment, a first inclined surface 110 is provided at the first end of the boss 11 along the circumferential direction.

[0030] Specifically, when the installation is completed, the first inclined surface 110 is close to the bottom of the groove 21 .

[0031] By providing a first inclined surface 110 along the circumferential direction at the first end of the boss 11 , the boss 11 can be automatically guided to cooperate with the groove 21 when the mold 20 and the mold shaft 10 are installed, thereby reducing position deviation and improving installation efficiency.

[0032] In one embodiment, a second inclined surface 210 is formed on the inner wall of the first end of the groove 21 along the circumferential direction.

[0033] Specifically, the first end of the groove 21 is close to the second end of the boss 11 when the installation is completed.

[0034] By providing the second inclined surface 210 along the circumferential direction at the second end of the groove 21 , the area of ​​the entrance of the groove 21 is increased, which facilitates the installation of the boss 11 and the groove 21 and improves the installation efficiency.

[0035] In one embodiment, the boss 11 is centrally disposed on the end of the mold shaft 10 , and the groove 21 is centrally opened on the end surface of the mold 20 .

[0036] The boss 11 and the groove 21 are designed to be centered, so that the force applied to the mold 20 and the mold shaft 10 can be easily received and evenly distributed, thereby enhancing the stability and durability of the overall structure.

[0037] In one embodiment, a mounting groove 12 is provided on the mold shaft 10 near the boss 11, and a threaded hole is opened on the outer wall of the mold shaft 10 inside the mounting groove 12. The mounting groove 12 is configured to provide an installation space for the positioning member 31, so that the positioning member 31 and the positioning groove 32 are located in the same plane.

[0038] By providing the mounting groove 12 on the mold shaft 10 , the positioning member 31 is effectively prevented from being offset during use, thereby enhancing the installation stability of the mold 20 .

[0039] In one embodiment, the positioning member 31 includes a positioning plate 310 and a bolt 311 . The positioning plate 310 is provided with a through hole corresponding to a threaded hole. The bolt 311 passes through the through hole and the threaded hole to fix the positioning plate in the mounting groove 12 .

[0040] The coordination of the bolts 311 , the threaded holes and the through holes not only ensures the secure installation of the positioning plate 310 , but also facilitates the quick assembly and disassembly of the positioning plate 310 , thereby improving overall work efficiency.
