Detailed Description

The present invention will be described in further detail with reference to the following examples, which are not intended to limit the invention.

As shown in fig. 1, the utility model provides an aluminum profile extrusion die with a porous structure, which comprises an upper die 1, a lower die 2, a positioning pin 3 and a connecting screw 4, wherein the positioning pin 3 is used for assembling and positioning the upper die and the lower die, the connecting screw 4 is used for connecting the upper die and the lower die together, the upper die 1 is provided with a shunting hole 11, a shunting bridge 12 and a die core 13, the shunting hole 11 is a passage for metal to a profile hole, the shunting bridge 12 is a support for supporting the die core 13, and the die core 13 is used for forming the shape and the size of an inner cavity of a profile; the lower die 2 is provided with a welding chamber 21, a die hole 22 and a blank cutter 23, the welding chamber 21 collects the metal flowing out from the shunting hole 11 together and welds the metal together again to form an integral material taking the die core 13 as the center, the static pressure is increased continuously due to continuous metal gathering until the metal is extruded out of the die hole 22, and the blank cutter 23 is used for reducing friction, so that the product can pass smoothly and the surface quality is ensured.

As shown in fig. 2, in this embodiment, the cross-sectional shape of the shunting holes 11 of the upper die 1 is a rhombus, and there are five shunting holes, one of the five shunting holes is located at the center of the die, the other four shunting holes are symmetrically arranged around the center of the die, the lower end of the shunting bridge 12 is designed to be an inverted bridge structure, the inclination angle of the inverted bridge structure is 20 °, the welding chamber 21 of the lower die 2 is divided into two parts, namely a left part and a right part, by a longitudinal partition wall 24 arranged at the center of the die, and the cross-sectional.

During production, aluminum materials are divided into a plurality of strands of aluminum streams through the shunting holes 11 of the upper die 1 under the action of an extruder, then the aluminum streams are collected in the welding chamber 21 of the lower die 2 and are welded again under the conditions of high temperature and high pressure, and finally the trapezoidal aluminum pipe section is extruded from the empty knife 23 through a gap between the die core 13 and the die hole 22.
