Further, the diameter of periphery tap hole is greater than extrusion billet diameter.
Further, punch-pin feed end sinking 40mm, broadening angle is 40 °, to reduce extruding force.
When punch-pin and die set work, aluminum alloy materials are divided by multiple periphery tap holes and intermediate distributary hole more
Money paid for shares belongs to stream, and with the flow velocity of balanced profile section each section, each money paid for shares belongs to stream and converges in bonding container, and work belt is entered after soldering
Hole obtains profile by mold core and the extrusion with holes that works.
A kind of production method of Semi surrounding type hollow aluminum section extrusion die, includes the following steps:
1) by above structure production punch-pin and cavity plate；
2) optimize angle, width and the periphery tap hole of each shunt bridge and the size in intermediate distributary hole in punch-pin to adjust
Profile section each position flow velocity；
3) optimize in cavity plate the size of choker bar and work size with holes to adjust profile section each position flow velocity；
4) emulation of step 2) and step 3) is carried out to extrusion die using the steady-state analysis method of HyperXtrude software
Sunykatuib analysis, until profile section each position flow velocity is uniform.
The present invention replaces traditional die trial process by using the method for numerical simulation, to the extrusion process of the profile
Sunykatuib analysis is carried out, and optimizes mould structure according to analog result, until profile section each section discharging speed is relatively uniform, is made
Profile forming quality meets the requirements, and effectively reduces die trial number, improves economic benefit.
The invention has the advantages that:
1, solve the problems, such as that there are uneven for profile mid-plane in Semi surrounding type hollow aluminum section extrusion process.
2, section quality and yield rate are improved, reduces subsequent re-shaping exercise amount, production efficiency improves 22.2%.
3, die trial process is replaced using the method for analogue simulation, die trial cost is made to decline 6.7%.

Specific embodiment
Technical solution of the present invention is described further with reference to the accompanying drawing.
Fig. 1 show a kind of sectional view of Semi surrounding type hollow aluminum section, and there are three irregular cavitys for the profile, is distributed in
The left and right sides is only connected by mid-plane.
Fig. 2 is the floor map of existing divergent die convex mould, and shunt bridge is designed on punch-pin and blocks mid-plane, due to
The inhomogeneities of shunt bridge two layers of material flow velocity, there is uneven defect in mid-plane after causing product to squeeze.
As shown in figures 3-8, which is by punch-pin 1 and cavity plate 2 to the extrusion die of the profile provided in this embodiment
Composition.
Punch-pin 1 is equipped with nine shunt bridges 103, and mold cavity is divided into seven periphery tap holes 101 penetrated through and one
Intermediate distributary hole 102, sets that there are three the mold cores 104 to forming profiles cavity in the shunt bridge 103.
Cavity plate 2 is equipped with the bonding container 201 being connected with periphery tap hole 101 and intermediate distributary hole 102, the bonding container 201
Bottom is equipped with the work with holes 202 to forming profiles outer surface.
With holes 202 mid-plane as shown in figure 3,102 face of intermediate distributary hole works.
Intermediate distributary hole 102, which flings feed, can guarantee that the plane upper and lower part flow velocity is uniform, and it is recessed to prevent mid-plane
The defect of convex injustice.
Since mid-plane is close to mold center, although intermediate distributary hole 102 flings feed and can guarantee that mid-plane is upper and lower
Portion flow rate is uniform, but the discharging speed that will cause mid-plane relative to other positions of profile section is very fast, influences profile
The uniformity of global sections speed.For this purpose, being all provided with choker bar 203 in work 202 two sides with holes of mid-plane, aluminium alloy is reduced

Belong to flowing, prevent from forming flow blind angle, it is preferred that the arc radius is 9mm.
Further, the diameter of periphery tap hole 101 is greater than extrusion billet diameter.
Further, punch-pin feed end sinking 40mm, broadening angle is 40 °, to reduce extruding force.
When 2 work in combination of punch-pin 1 and cavity plate, aluminium is closed by seven periphery tap holes 101 and an intermediate distributary hole 102
Golden material is divided into stereotyped writing metal stream, and with the flow velocity of balanced profile section each section, each money paid for shares belongs to stream and converges in bonding container 201,
Enter work belt hole 202 after soldering, profile is obtained by mold core 104 and 202 extrusion with holes that works.
A kind of production method of Semi surrounding type hollow aluminum section extrusion die, includes the following steps:
1) by above structure production punch-pin 1 and cavity plate 2；
2) optimize angle, width and the periphery tap hole 101 of each shunt bridge 103 and intermediate distributary hole 102 in punch-pin 1
Size adjusts profile section each position flow velocity；
3) optimize the size of choker bar 203 in cavity plate 2 and with holes 202 size of working further to adjust profile section each
Position flow velocity；
4) emulation of step 2) and step 3) is carried out to extrusion die using the steady-state analysis method of HyperXtrude software
Sunykatuib analysis, until profile section each position flow velocity is uniform.
The present invention replaces traditional die trial process by using the method for numerical simulation, to the extrusion process of the profile
