The mother die is composed of a coaxial upper die and a lower die, and an annular insert is arranged in the mother die. The lower die is provided with a first die hole with a larger aperture. The lower die adopts a keyway to detachably set the annular insert. By changing the aperture of the second die hole and the annular inserts of the annular working belts of different diameters, pipes with different wall thicknesses can be produced. However, this technical solution can only realize the extrusion production of aluminum profiles with different wall thicknesses under the same aperture, and for pipes with different apertures, the entire die needs to be replaced.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 To Attachment Figure 7 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0022] like Figure 1As shown, a universal conversion mold for standard profiles includes an upper mold 1 and a lower mold 2 that are connected to each other and coaxially arranged. The upper mold 1 and the lower mold 2 can be detachably connected in a conventional manner, such as being mutually clamped or connected by pins. The upper mold 1 includes a mold body 3 and a flow guide mold 12 that is coaxially arranged with the mold body 3.

[0023] like Figure 2 and Figure 3 As shown, on the mold body 3, with the axis of the mold body 3 as the center, a plurality of first diversion holes 4 are distributed along the circumference of the mold body 3, and a first diversion bridge 5 is formed between two adjacent first diversion holes 4. A detachable core block 6 is also provided on the end surface of the mold body 3, and the core block 6 is coaxially arranged with the mold body 3. The core block 6 and the mold body 3 can be detachably connected by a plurality of first positioning pins 10, or by other conventional methods.
