The aluminum profile extrusion die is characterized in that an aluminum column is extruded from an upper die 10, the aluminum column sequentially passes through a feeding hole 12, a first-level feeding sinking bridge 11, a buffer platform 13 and a second-level feeding sinking bridge 14, then flows into a lower die 20 from a die head 16 and the feeding hole 12 to be welded together, and then is extruded to obtain a formed aluminum profile, when the aluminum column is extruded, the aluminum column is firstly contacted with the first-level feeding sinking bridge 11 and is extruded to a certain extent, so that the aluminum column subjected to high-temperature treatment can form downward flowing of aluminum liquid, the aluminum liquid outside the first-level feeding sinking bridge 11 can flow downward through the feeding hole 12, a part of the aluminum liquid in the middle of the first-level feeding sinking bridge 11 flows to the buffer platform 13, and a part of the aluminum liquid directly flows to the second-level feeding sinking bridge 14 to be extruded for secondary extrusion, the buffer platform 13 plays a role in slowing down the extrusion pressure of the second-level feeding sinking bridge 14 to help the second-level feeding sinking bridge 14 to reduce a certain pressure, and particularly, when the aluminum column is extruded through the first-level feeding sinking bridge 11, the aluminum liquid can be extruded to be prevented from flowing into the second-level feeding sinking bridge 14 to flow into the buffer platform 13 in batches, and the second-level feeding sinking bridge 14 to be extruded to be branched into the die head.

The die heads 16 are connected to the bottoms of the supporting columns 15, the space portions 18 are arranged between every two adjacent die heads 16, aluminum liquid passes through the space portions, the supporting columns 15 play a role in reinforcing the die heads 16 and preventing the die heads 16 from deforming, large extrusion force (the space portions 18 are not large in width) can be generated on the die heads 16 due to the fact that the aluminum liquid flows through the die heads 16 under extrusion pressure, the die heads 16 are prone to deforming, partial pressure can be shared under the protection of the supporting columns 15, and the die heads 16 are prevented from deforming too early.

The flow guide grooves 17 are arranged between the two adjacent support columns 15, the flow guide grooves 17 are used for accelerating the flow of part of the aluminum liquid, specifically, the aluminum liquid flowing in through the extrusion of the feeding hole 12 can quickly reach the lower die 20, and the aluminum liquid can quickly flow to the lower die 20 through the die head 16 in order to accelerate the flow rate of the middle aluminum liquid, so the flow guide grooves 17 are arranged between the two adjacent support columns 15, the flow guide grooves 17 arranged obliquely can accelerate the flow of the aluminum liquid, so that the aluminum liquid can quickly reach the die head 16 and can be extruded to the lower die 20, and the aluminum liquid from the feeding hole 12 can be converged in the lower die 20 in approximately the same time.

The utility model discloses a set up buffering platform 13, one-level pan feeding sinking bridge 11 and second grade pan feeding sinking bridge 14, the buffering has reduced the impact force that aluminium column extrusion in-process brought last mould 10, make it can not too early emergence type become or collapse to go up mould 10, the life of mould has been increased, through setting up support column 15, protection die head 16 that can be better is not become by aluminium liquid extrusion type, ensure to need not often to change die head 16, through setting up guiding gutter 17, can ensure that middle part aluminium liquid and the aluminium liquid that gets into from pan feeding hole 12 arrive lower mould 20 with the same time and join, make the aluminium alloy texture of production all with, be difficult for producing the welding seam.

Further, the diversion trench 17 is disposed in an inclined manner, and the inclination angle of the diversion trench 17 is 45 °.

The flow guide grooves 17 are obliquely arranged, so that the flow of the aluminum liquid can be accelerated, the aluminum liquid has certain viscosity and can rub against the inner side wall of the upper die 10, and the flow guide grooves 17 with the inclination angle can accelerate the flow of the aluminum liquid, so that the aluminum liquid can reach the die head 16 at a higher speed to be extruded.

In a further description, the lower mold 20 includes a discharge hole 21, the discharge hole 21 is disposed in the middle of the lower mold 20, and the aluminum profile is extruded out of the mold through the discharge hole 21.

In a further description, the lower mold 20 further includes a first-stage welding chamber 22 and a second-stage welding chamber 23, the second-stage welding chamber 23 is disposed at the periphery of the discharge hole 21, and the first-stage welding chamber 22 is disposed at the periphery of the second-stage welding chamber 23.

The primary welding chamber 22 and the secondary welding chamber 23 are used for welding the aluminum liquid flowing from the feeding hole 12 in the lower die 20, so that the aluminum liquid reaches a certain hydrostatic pressure, and a welding seam cannot appear on a subsequent extruded aluminum section.

In a further illustration, the mold further comprises a first annular flange 30, and the first annular flange 30 is disposed on an outer side wall of the upper mold 10.

A first annular flange 30 is provided on the outer side wall of the upper die 10, the first annular flange 30 being capable of mating with a second annular flange 40 at the top of the lower die 20.
