In some embodiments, the back aperture 500 is located forward of the forming groove 214 and is not in communication with the lower die 100 (which would otherwise alter the profile configuration). The shape and the size of the back hole are determined according to the shape of the profile.

In some embodiments, the front side of the lower mold 100 is provided with a flow blocking table 110, which can cope with the characteristic that the molten aluminum will be outwardly supported when passing through the cavity structure, and is sufficient to ensure the accuracy of the frame position of the profile.

It is sufficient to ensure the shaping effect of the central rib. The ratio of the shortest aperture of the left and right shunting holes 450 to the shortest aperture of the upper and lower shunting holes 440 is

The left and right diverging holes 450 are farther from the extrusion center and therefore require larger hole diameters.

In some embodiments, the front side of the guide plate 300 is concavely provided with a front guide hole 460, and the front guide hole 460 is communicated with the guide channel 400, so that the size of the diversion hole can be easily calculated, and the speed of the extrusion of the section bar can be adjusted by the area size of the diversion hole.

The present invention can be modified and adapted appropriately from the above-described embodiments, according to the principles described above. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should fall within the scope of the claims of the present invention.
