Abstract
The invention provides a porous magnesium extrusion mold. A boss is arranged in the center of a discharge surface of an upper mold of the mold; the boss is rectangular; four dividing bridges are uniformly distributed at four corners of the boss; four dividing cavities are formed among the four dividing bridges; wiring nozzles are respectively arranged on the four dividing bridges of the upper mold; the positions of the four wiring nozzles correspond to those of four fixed diameters of a feeding surface of a lower mold; wiring holes are formed in four angle ends of a feeding surface of the upper mold; two welding chambers are arranged in a feeding surface of the lower mold; the rear end of each fixed diameter is communicated with an escape hole; fourth change air blades are arranged on a feeding surface of a mold backer. The porous magnesium extrusion mold has the beneficial effects that the boss of the upper mold has the functions of support and division, meanwhile the friction function of a magnesium material with the mold can be reduced, the magnesium material can relatively easily enter the dividing holes around the boss, the extrusion pressure is reduced by 20%, the rapid extrusion is achieved, the extrusion speed is increased by 40%, the production efficiency of magnesium-magnesium extrusion is greatly improved by 120-160%, and the cost is lowered by 30-60%.
Description
Technical field
The present invention relates to a kind of porous type magnesium extrusion die, belong to magnesium die technical field.
Background technology
Magnesium extrusion die is in the past all based on single hole Design of Dies, so that plant site production operation and repairing a die.But along with the fast development of magnesium industry, the production of a high flow rate can not form competitiveness, can only could meet industry development needs by High-efficient Production.Multiple-hole die design immediately constantly occurs, but all fails to reach desirable poised state, and its squeeze pressure is comparatively large, and extrusion speed is slow, and production efficiency is low, and distortion is large, front and back discharging is unstable, therefore fails to be popularized.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of porous type magnesium extrusion die, its squeeze pressure is less, can realize crushing failure at high speed, substantially increase production efficiency.
For achieving the above object, the technical solution used in the present invention is to provide a kind of porous type magnesium extrusion die, this mould includes patrix, counterdie, die-cushion, wherein: described patrix goes out charge level center and is provided with boss, described boss is rectangle shape, the corner of boss is evenly equipped with four shunting bridges, four branch chamber are formed between four shunting bridges, described patrix four shunting bridges are respectively arranged with and wear a mouth, described four positions of wearing a mouth are corresponding with the position of the sizing of four on counterdie charging face, four, patrix charging face angle end is provided with wire hole, being through to four wears in the middle of a mouth, described counterdie charging face is provided with two bonding container, the center of described two bonding container is corresponding with the center that four are worn a mouth, and the rear end of each sizing is communicated with escapes emptying aperture, described die-cushion charging face is provided with four empty swords, described empty sword is corresponding with the position of escaping emptying aperture on counterdie.
The shape of described bonding container is petal-shaped, described in escape emptying aperture shape in trumpet-shaped through hole.
Effect of the present invention is the patrix boss of this porous type magnesium structure of extrusion, the effect supporting and shunt can be played, the rubbing action of magnesium material and mould can be reduced simultaneously, magnesium material more easily enters in the tap hole of boss surrounding, its squeeze pressure reduces 20%, and can realize crushing failure at high speed, extrusion speed improves 40%, substantially increase the production efficiency 120% ~ 160% of magnesium magnesium extruding, reduce costs 30 ~ 60%.

Detailed description of the invention
By reference to the accompanying drawings the structure of porous type magnesium extrusion die of the present invention is illustrated.
Porous type magnesium extrusion die of the present invention, this mould includes upper die and lower die, die-cushion, described patrix goes out charge level center and is provided with boss 10, described boss 10 is rectangle shape, the corner of boss 10 is evenly equipped with four shunting bridges 11, four branch chamber 1 are formed between four shunting bridges 11, described patrix four shunting bridges 11 are respectively arranged with and wear a mouth 9, described four positions of wearing a mouth 9 are corresponding with the position of the sizing of four on counterdie charging face 3, four, patrix charging face angle end is provided with wire hole 8, is through to four and wears in the middle of a mouth 9; Described counterdie charging face is provided with two bonding container 2, the center of described two bonding container 2 is corresponding with the center that four are worn a mouth 9, and the rear end of each sizing 3 is communicated with escapes emptying aperture 12; Described die-cushion 5 charging face is provided with four empty swords 4, described empty sword 4 is corresponding with the position of escaping emptying aperture 12 on counterdie 6.
The shape of described bonding container 2 is petal-shaped, described in escape emptying aperture 12 shape in trumpet-shaped through hole.
Porous type magnesium extrusion die function of the present invention is achieved in that
During porous type magnesium extrusion die of the present invention uses, flow in bonding container 2 through shunting bridge 11 after blank is pressed into four branch chamber 1 by extruding force, blank enters bonding container 2 and drives a special mouth 9 steel wire of wearing to move together, steel wire is sandwiched in blank, bonding container 2 effectively keeps the flow velocity in four holes unanimously to flow into four corresponding sizings 3, the marginal portion of the extruded product under extruding force effect, by way of sizing 3 internal diameter, can effectively ensure surface quality and dimensional accuracy.Center with steel wire by the extruded product of sizing 3 be squeezed in trumpet type escape emptying aperture 12 and empty sword 4 after become shaping extruded product.
In porous extrusion process, the highest breakthrough pressure extrudes 20MPa by single hole, is reduced to 16MPa.Pressure ram speed extrudes 2mm/s by single hole, is increased to 2.8mm/s, boosts productivity 150%, effectively reduces costs 50%.
