Description
Technical field
The present invention relates to a kind of hot-extrusion mold, especially relate to a kind of multi-structure motor enclosure aluminium alloy hot-extrusion die.Belong to the aluminium section die technical field.
Background technology
Along with the industrial expansion demand, the demand of motor casing is also increasing, and a lot of motor housings adopt aluminium alloy form (as Figure 11) by original cast iron formal transformation, and its major advantage is: cost is low, dimensional accuracy is better, manufacturing procedure is less, easily forms and produces in batches.Present this aluminium alloy electric casing mainly is by hot-extrusion mold production, but also there are many weak points in this type of mould, as:
1, because hollow-core construction is more, and patrix core rod intensity is lower, be prone to fracture or beat phenomenon, output is not high.
2, because of hollow-core construction junction feed difficulty, easily cause wall unevenness or cause that circle is under feeding in the motor casing, and form ellipse, do not satisfy dimension precision requirement.
3, because of wall thickness differs greatly, flow velocity is difficult to adjust, and motor casing easily draws to become to turn round twists and crooked, does not satisfy linearity and flatness requirement, and the while outer surface easily produces phenomenons such as feel.
4, because of the patrix core rod is bigger, pressure is higher, and patrix insufficient strength and cause splitting bridge causes die life not high.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of metal flow equilibrium that makes is provided, can satisfy inside and outside round feed requirement, can guarantee simultaneously inside and outside round ovality requirement, surface quality and dimension precision requirement again, can also guarantee die life, improve the multi-structure motor enclosure aluminium alloy hot-extrusion die of mould output.
The object of the present invention is achieved like this: a kind of multi-structure motor enclosure aluminium alloy hot-extrusion die, it is characterized in that it is formed by stacking by water conservancy diversion mould, upper die and lower die front and back,
Described water conservancy diversion mould charging face is provided with seven bridge locations, forms seven tap holes between the bridge location, and tap hole is expanded towards periphery and formed tap hole expansion place;
Described patrix charging face is provided with seven bridge locations, form seven charging punishment discharge orifices between the bridge location, patrix goes out charge level and is provided with 21 discharging punishment discharge orifices, in 21 discharging punishment discharge orifices are divided into, outer two circles, wherein there are 14 tap holes the outer ring, inner ring has seven tap holes, and each charging punishment discharge orifice of patrix charging face is corresponding with per three dischargings punishment discharge orifice that patrix goes out charge level, seven tap holes of inner ring satisfy the feed requirement of circle in the motor casing, 14 tap holes in outer ring then satisfy the feed requirement of motor casing cylindrical, form bridge location in the tap hole between the discharging punishment discharge orifice, there are eight core rods the bridge location intersection in the tap hole, eight core rods are divided into core rod of seven core rods in outer ring and center, being provided with conduction hole between outer ring core rod and the central core separates, the bridge location junction forms bevel-type and tiltedly draws the oblique interim form of formation between central core and the inner ring tap hole in outer ring core rod and the tap hole;
Be concaved with the seam chamber under in the middle of the described counterdie charging face, the indoor edge of the seam front portion of corresponding section bar wall thickness thicker part is provided with two choked flow projections, is used to control the flow velocity at section bar heavy wall place.
Compare with existing similar mould, the present invention has following advantage:
1, adopts the water conservancy diversion modular form, so both can satisfy the feed requirement of the inside and outside circle of motor casing more uniformly, also can bear extruding force greatly simultaneously, patrix is played a protective role, reduce mould and split the bridge phenomenon.
2, adopt seven tap holes, can satisfy the feed requirement at each position, make the feed of inside and outside die cavity balanced, pressure is consistent, reduces inclined to one side wall phenomenon, has also guaranteed the ovality of inside and outside circle simultaneously.
3, the patrix core rod adopts and tiltedly draws the protection form, has guaranteed the intensity of core rod.
4, seven tap holes are adopted in the patrix charging, and 21 tap holes are adopted in discharging, and internal, outer die cavity guarantees than balancing flow, reduce section bar and turn round phenomenons such as stubborn, bending.
5, counterdie is provided with choker bar, and the flow velocity of the thick material part of assurance that can be balanced and the flow velocity uniformity of thin material part can reduce the phenomenons such as feel that the surface occurs simultaneously.
In sum, mould of the present invention can make the metal flow equilibrium, can satisfy inside and outside round feed requirement, can guarantee inside and outside round ovality requirement, surface quality and dimension precision requirement again simultaneously, can also guarantee die life, improves mould output.
