Extrusion dies for complex cross-section aluminum profiles deform aluminum material into various complex cross-sections during the extrusion process.

[0003] When using existing aluminum profile extrusion dies, after the aluminum profile is extruded on the die table, the aluminum profile will stick to the top of the die table and the surface of the punch. It is not possible to shake or vibrate the punch to loosen the aluminum profile, making it inconvenient to demold and remove. Moreover, when extruding aluminum profiles with different complex cross-sections, it is inconvenient to change to punches with different complex cross-sections for extrusion molding.

[0004] Therefore, a complex cross-section aluminum profile extrusion die is provided. Utility Model Content

[0028] The connecting mechanism includes a connecting rod 6 and an engagement mechanism; the connecting rod 6 is evenly fixed at the bottom end of the punch 10, and the surface of the mold table 8 is evenly provided with insertion holes 9. The connecting rod 6 slides through the insertion holes 9, and a nut 15 is connected to the surface of the connecting rod 6. A spring 20 is slidably sleeved on the surface of the connecting rod 6 at the position between the insertion holes 9 and the nut 15.

[0029] A connecting hole 18 is provided on the surface of the connecting rod 6 and below the nut 15. The connecting hole 18 is a threaded hole and is set horizontally. The internal thread of the connecting hole 18 passes through the snap-fit ​​rod 14. The snap-fit ​​rod 14 is a threaded rod and is horizontally connected between the two connecting rods 6 and located above the gear 3.

[0030] A pressure plate 11 is fixed to the top of the die 16. The pressure plate 11 is horizontally set above the mold table 8. A top plate 12 is installed on the top of the pressure plate 11. The top plate 12 is horizontally set. A hydraulic telescopic rod 13 is installed in the middle of the top of the top of the top plate 12. The hydraulic telescopic rod 13 is vertically set. The bottom end of the hydraulic telescopic rod 13 is fixed to the middle of the top of the pressure plate 11. Guide holes 17 are opened at the four corners of the pressure plate 11. Guide rods 2 that slide through the guide holes 17 are fixed between the four corners of the top of the base 1 and the four corners of the bottom of the top plate 12.

[0031] The base 1 is a rectangular structure and is horizontally set. The mold table 8 is a rectangular plate structure and is horizontally set. Support legs 7 are fixed between the four corners of its bottom end and the top of the base 1.

[0032] The connecting rod 6 is a threaded rod structure and is vertically arranged. There is a gap between its bottom end and the top end of the base 1. The tooth groove 19 is horizontally arranged and meshes with the gear 3 for transmission.

[0033] In use, by setting a plug hole 9 at the top of the mold table 8, the connecting rod 6 at the bottom of the punch 10 passes through the plug hole 9 and then abuts against the spring 20 through the nut 15 and is connected to the surface of the connecting rod 6. The spring 20 is in a compressed state, which can stably install the punch 10 on the mold table 8 to extrude and form aluminum profiles. Therefore, punches 10 with different complex cross sections can be disassembled and replaced on the mold table 8 through the plug rod 6, nut 15 and spring 20, which is convenient for extruding and forming aluminum profiles with different complex cross sections.

[0034] Example 2: A complex cross-section aluminum profile extrusion die, such as Figures 1-4 As shown, the meshing mechanism includes a gear 3 and tooth grooves 19.

[0037] In use, by setting toothed grooves 19 on the side of the connecting rod 6 and meshing gear 3 on the side of the toothed grooves 19, after the complex cross-section aluminum profile is extruded and formed on the mold table 8, the servo motor 5 drives the gear 3 to rotate. The gear 3 meshes with the toothed grooves 19 to drive the connecting rod 6 to move upward elastically in conjunction with the spring 20. Since the toothed grooves 19 are located at the bottom of the connecting rod 6 and the gear 3 is close to the bottom of the connecting rod 6, during the rotation of the gear 3, through the meshing transmission with the toothed grooves 19, the connecting rod 6 is driven to move up and down continuously and is bounced by the spring 20, thereby causing the punch 10 to shake and vibrate up and down on the mold table 8, which facilitates the loosening and removal of the aluminum profile.
