The terms "first", "second", etc. in the specification and claims of the present utility model or the above drawings are used to distinguish different objects and not to describe a specific order.

[0029] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0030] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0031] As Figures 1-4 shown, it is an embodiment provided by the present utility model.

[0032] An embodiment of the utility model provides a die pressing device for an aluminum profile extruder, including: a mounting base 10, a die 20, and a die base 30. The die 20 and the die base 30 are respectively arranged on the front side wall of the mounting base 10. A forming channel 11 penetrating through from front to back is arranged in the middle of the mounting base 10. The die 20 is coaxially arranged at the front end of the forming channel 11. The die base 30 surrounds the die 20 and is used to provide support for the die 20. Among them, the die base 30 is in a groove shape. The inner side wall of the die base 30 is supported and connected to the outer side wall of the die 20. The shape of the groove is adapted to the shape of the die 20 and can support the lower half of the die 20 in a wrapping manner, which can not only stably support the die 20 but also facilitate the removal of the die 20 from the die base 30. A pushing mechanism 40 in the same direction as the die base 30 is arranged through the rear side wall of the mounting base 10. The front end of the pushing mechanism 40 is movably abutted against the rear end of the die 20 and can push the die 20 forward. A positioning support 31 is arranged at the front end of the die base 30. A step 21 is arranged around the front end of the die 20. The step 21 is formed by cutting and processing the front end of the die 20. The pushing mechanism 40 can push the die 20 forward, so that the front end of the die 20 is inserted into the positioning support 31, forming a downward limit on the front end of the die 20, and the step 21 abuts against the inner end of the positioning support 31, generating a forward limit on the die 20, thereby fixing the front end of the die 20 and avoiding the problem that the front end of the die 20 is pressed downward and inclined during the shearing of the press residue, resulting in uneven shearing surfaces of the profile.

[0033] Further, the positioning support 31 is in a U shape or a semi-circular ring shape, the die 20 is in a cylindrical shape, and the inner diameter of the positioning support 31 is the same as the outer diameter of the front end of the die 20, so that the positioning support 31 and the front end of the die 20 form a tightly assembled relationship similar to socket connection. In addition, the thickness of the positioning support 31 is less than or equal to the length from the bottom wall of the step 21 to the front end of the die 20, so that the front end of the positioning support 31 does not exceed the front end of the die 20 and block the shearing of the press residue.

[0034] Further, a supporting platform 32 is arranged at the bottom of the die base 30, and a pressing platform 33 is arranged at the top of the die base 30. The pressing platform 33 abuts against the die base 30. The pressing platform 33 can limit the top of the die 20. The die base 30 is slidably connected to the supporting platform 32. The supporting platform 32 is fixedly installed on the front side wall of the installation table, and a horizontally transverse slide rail is arranged on its top. A corresponding chute is arranged at the bottom of the die base 30, so that the die base 30 can only move horizontally and cannot move back and forth. When installing or replacing the die 20, only need to move the die base 30 to one side of the pressing platform 33 to release the limit on the top of the die 20 by the pressing platform 33, which is convenient for the replacement and installation of the die 20.

[0035] Further, the front side walls of the supporting platform 32 and the pressing platform 33 are flush with the front end of the die base 30, which is convenient for the shearing mechanism 12 to cut off the profile press residue at the front end of the die 20 and ensure the flatness of the cutting surface.

[0036] Specifically, the pushing mechanism 40 includes an oil cylinder 41 and a push rod 42. The oil cylinder 41 is arranged on the rear side wall of the mounting seat 10. The rear end of the push rod 42 is connected to the telescopic end of the oil cylinder 41. The front end of the push rod 42 penetrates into the mounting seat 10 and abuts against the rear end of the mold 20. In order to ensure the balanced force on the rear end of the mold 20 during pushing, three groups of pushing mechanisms 40 are provided. The three groups of pushing mechanisms 40 are evenly distributed around the forming channel 11. The front ends of the three push rods 42 evenly abut against the rear end of the mold 20 along the circumferential direction.

[0037] As Figure 5 shown, the present utility model further provides: an extruder, including a shearing mechanism 12 and the mold pressing device of the above aluminum profile extruder. The shearing mechanism 12 is arranged on the front side wall of the mounting seat 10 and is located above the mold 20 and the mold base 30. The shearing mechanism 12 includes a telescopic oil cylinder 41 and a cutter. The telescopic oil cylinder 41 can drive the cutter to move downward to cut off the excess material at the front end of the mold 20.

[0038] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all of them.
