Described conducting element and mesopore shaping column stretch in described discharging opening.
Supplementing as such scheme, the same plane that described discharging opening, core and mesopore shaping column are arranged in described discharging opening is provided with mold hole work belt.
Supplementing as such scheme, the length of described mold hole work belt is 2-15mm.
Supplementing as such scheme, described conducting element is trumpet type, and the end of described conducting element is provided with side opening profiled member.
Supplementing as such scheme, described conducting element is provided with flow-guiding channel, and described flow-guiding channel diminishes gradually on the moving direction of metallic aluminium.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-Figure 4, the utility model embodiment provides a kind of extrusion die, comprises patrix 1, core 2 and counterdie 3, and described patrix 1, core 2 are connected in turn with counterdie 3,
Described patrix 1 comprises upper die body 11, is evenly located at the first charging hole 12 on upper die body 11, and is located at upper die body 11 center and stretches out the mesopore shaping column 13 of described upper die body 11 upper surface;
Described counterdie 3 comprises lower mold body 31, and described lower mold body 31 is provided with lower mode cavity 32, and described lower mode cavity 32 is communicated with the discharging opening 33 be located at bottom it;
Described core 2 comprises core block 21, and described core block 21 is provided with core chamber 22, is provided with conducting element 23 in the middle part of described core chamber 22, and core chamber 22 is separated into outer shaping area 22a and shaping area, middle part 22b by described conducting element 23;
Described conducting element 23 and mesopore shaping column 13 stretch in described discharging opening 33.
The utility model by adding core 2 between patrix 1 and counterdie 3, conducting element 23 is provided with in the middle part of described core chamber 22, the metallic aluminium entering die working length (forming surface) is shifted to an earlier date subregion by described conducting element 23, reduce metallic aluminium in extrusion process and, at the current difference of mould different parts, improve Forming Quality.
Wherein, the same plane that described discharging opening 33, core 2 and mesopore shaping column 13 are arranged in described discharging opening 33 is provided with mold hole work belt 4.Described mold hole work belt 4, namely as the forming surface of mould, is used for ensureing the mould side wall extruding size of aluminium.The length of described mold hole work belt 4 is 2-15mm.The length that mold hole work belt 4 within the scope of this compares general mold hole work belt 4 is little, can reduce the impact of mold hole work belt 4 on metallic aluminium extruded velocity, and metallic aluminium extruded velocity is consistent.
