Description
Technical field
Magnesium alloy profile extrusion die design field is the utility model is related to, it is hollow more particularly to a kind of magnesium alloy
Stuff extrusion mould.
Background technology
Magnesium alloy is metal most light in structural material, has small density, specific strength and specific stiffness height, damping shock-absorbing noise-reducing
The advantages such as ability is strong, capability of electromagnetic shielding is excellent and is easily recycled, it is described as " 21 century green structural material ".In recent years
Come, magnesium types material obtains a wide range of applications in fields such as the vehicles, electrical equipment industry, Aero-Space and defence and militaries, into
It is fast-developing in the world for the 3rd metalloid material after steel and aluminium.But the solid matter six of magnesium alloy itself
Square structure determines that the material slide surface is less, and deformation plasticity is markedly less than aluminium alloy.Therefore, under the conditions of same structure, magnesium
The yield rate of alloy profile is lower, is mainly manifested in that magnesium types material egress rate and pressure inhomogeneities are too high to cause section bar deformation tight
The problems such as weight is with face checking, this Extrusion Die Design to magnesium alloy profiles and exploitation propose higher requirement.
Utility model content
The utility model is in order to overcome the above-mentioned deficiencies of the prior art, there is provided a kind of magnesium alloy hollow shaped material extrusion die
Lamps structure, design is simple, is easy to process, and under the premise of ensureing that magnesium types material egress rate and pressure are uniform, can control section bar
Size and wall thickness accuracy, improve formed product rate.
Technical scheme is used by the utility model：A kind of magnesium alloy hollow shaped material is semicircle special pipe structure, its
Extrusion die includes the divergent die and shaping mould being superimposed up and down, and the divergent die enters charge level and is provided with four sector diffuence-holes, point
Shunting bridge is provided between discharge orifice, the shunting die discharge face center is provided with core, and the shaping mould enters charge level setting
There are bonding container and nib, choked flow side is provided with the bonding container, work band is provided with the nib.
On the basis of above-mentioned technical proposal, including following attached technical scheme：
The semicircle special pipe structure of the magnesium alloy profiles, its circular arc portion and non-circular arc portion caused by the structure opposite sex into
Type speed and pressure gap are larger.
Four sector diffuence-hole symmetric designs and distribution, in the same size on the divergent die.
The divergent die upper core centre symmetry line overlaps with upper and lower tap hole centre symmetry line.
Choked flow side is symmetrically wrapped in the non-circular arc side of nib in the bonding container, is highly 2mm, thickness 1-2mm.
Compared with prior art, the beneficial effects of the utility model are：
A kind of magnesium alloy hollow shaped material extrusion die of the utility model, its profile structure are semicircle special pipe, and mould is adopted
Metal stream material is split with four in the same size, symmetrical sector diffuence-holes, simplifies design and difficulty of processing；Divergent die goes out
Charge level center is provided with core, and its centre symmetry line overlaps with upper and lower tap hole centre symmetry line, ensure that more difficult shaping
Circular arc portion is substantially distributed in below tap hole, and non-circular arc side concentrates on soldering position below shunting bridge；Further to prevent
Section bar exit velocity and pressure are uneven, and it is 1-2mm, the highly resistance for 2mm to set up thickness in the non-circular arc side being easily molded
Side is flowed, strengthens balance feed and is distributed with uniform pressure.

Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in figs. 1-7, the utility model provides a kind of specific embodiment of magnesium alloy hollow shaped material extrusion die.
The magnesium alloy profiles are semicircle special pipe structure, its circular arc portion molding rate and pressure caused by the structure opposite sex with non-circular arc portion
Power differs greatly.The profile extrusion die is combined by the divergent die being superimposed up and down with shaping mould.The divergent die enters charge level
Four sector diffuence-hole 1-4 are provided with, it is in the same size, symmetrical, to reduce design and difficulty of processing；Set between tap hole
There is shunting bridge 5；The shunting die discharge face center is provided with core 6, its centre symmetry line and upper and lower tap hole 1,3 centers
Line of symmetry overlaps, and to ensure that the circular arc side of more difficult shaping is substantially distributed in below tap hole, non-circular arc side concentrates on shunting
Soldering position below bridge；The shaping mould enters charge level and is provided with bonding container 7 and nib 8, further to prevent section bar outlet stream
Speed is uneven with pressure distribution, and choked flow side 9 is provided with bonding container 7, is symmetrically wrapped in non-circular arc side of the nib compared with easy-formation,
Thickness is 1-2mm, is highly 2mm, to strengthen balance feed and uniform pressure distribution；Work band is provided with the nib 8
10, ensure that magnesium types material is smoothly extruded.
