Description
Technical field
This utility model belongs to pressure cast aluminum-alloy wheel mould applications, be specifically related to a kind of can automatic demoulding aluminum close
Gold low pressure casting die.
Background technology
Along with the development of aluminum-alloy wheel, common aluminum-alloy wheel moulding can not meet the esthetic requirement of client,
Occurring a kind of aluminum-alloy wheel currently on the market, structure is: draw out a ring the deepest at the delivery position of spoke and wheel rim
Shape draws material, and such structure not only makes wheel seem slender agile, and chromatography product contrast color is obvious, more important
Be some the overall weight significantly reducing wheel.But such wheel also exists one during low pressure casting produces
Fixed difficulty, especially die casting and machining sequence, in press casting procedure, this kind of structure wheel to be ensured for existing mold takes off
The smooth thermal center of mould is inevitable the biggest, there will be some defects of die castings in press casting procedure, and the most significantly open defect is exactly that machine adds
Visible shrinkage cavity after work；For corresponding machining sequence, cutting output is big, and the serious wear of cutter, long processing time, production efficiency is low.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of can the low die casting of aluminium alloy of automatic demoulding
Modeling has, and solves the deep annular at aluminum-alloy wheel thermal center and draws withdrawing pattern problem when expecting casting.
The technical solution of the utility model: a kind of can the aluminum alloy low-pressure casting mould of automatic demoulding, by backform, aluminium profiles
Composition is touched on core, bed die and limit, it is characterised in that aluminium profiles core utilizes the compression stress of jump ring to coordinate with backform, aluminium profiles core, backform, the end
Mould and limit mould are collectively forming foundry goods die cavity；Described aluminium profiles core is made up of the thin circle of aluminum, wedge metal ring and jump ring；Described wedge shape
Becket, the upper port internal diameter soldering of its lozenges circle thin with aluminum is connected, uniform 5 jump rings of spot welding on its inwall, and wedge shape gold
The withdrawing pattern direction belonging to ring is identical with the direction of motion of backform during matched moulds；Designing a positioning spigot on described backform, location is only
Mouth wide 8mm, long 10mm and draft angle are 3 °, and its effect is fixing aluminium profiles core.
The utility model has the advantages that: deep annular at wheel thermal center can be drawn material die cast by this structure, and can be suitable
The profit demoulding, it is to avoid the blocked up defects of die casting caused of thermal center, machining time is short simultaneously, and efficiency is high, and metal gasket ring therein is through place
Recoverable after reason, saves production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing in Fig. 1 at A.
In figure: 1. backform, 2. aluminium profiles core, 3. bed die, 4. limit mould, 5. jump ring, 6. wedge metal ring, the 7. thin circle of aluminum.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, this utility model is described further.
A kind of can the aluminum alloy low-pressure casting mould of automatic demoulding, backform 1, aluminium profiles core 2, bed die 3 and limit touch 4 and form.
It is characterized in that, aluminium profiles core 2 utilizes the compression stress of jump ring 5 to coordinate with backform 1, and aluminium profiles core 2, backform 1, bed die 3 and limit mould 4 are common
Form foundry goods die cavity.Designing a positioning spigot on described backform 1, positioning spigot width 8mm, long 10mm and draft angle are 3 °,
Its effect is fixing aluminium profiles core 2.
Described aluminium profiles core 2 is made up of the thin circle of aluminum 7, wedge metal ring 6 and jump ring 5, in the upper port of the thin circle of described aluminum 7
Footpath is brazed together with the outer surface i.e. lozenges of wedge metal ring 6, on the inwall i.e. face of cylinder of described wedge metal ring 6 all
5 jump rings 5 of even spot welding, and wedge metal ring 6 withdrawing pattern direction is identical with the direction of motion of backform during matched moulds 1, its effect is when top
When masthead goes out foundry goods, it is to avoid occur that wedge metal ring 6 departs from aluminum thin circle 7 and make wedge metal ring 6 stay on backform 1, this structure
Necessarily make aluminium profiles core 2 depart from backform 1 under the common effect of design and jump ring 5 to be retained on foundry goods.The effect of described aluminium profiles core 2
It is the jump ring when aluminium profiles core 2 is arranged on backform 1 on backform seam face extruded aluminium core 2, utilizes the power that jump ring 5 compresses by aluminum
Core 2 is quickly fixed on backform 1, and when push rod ejects, aluminium profiles core 2 can depart from backform 1 smoothly, completes quick assembling and smoothly
The process of the demoulding.
Described bed die 3, backform profile line 2mm to be less than at the bed die window molded line at wheel thermal center, near wheel
The bed die window molded line at spoke position is identical with backform profile line, is that bed die 3 plays fixing aluminium profiles core 2 when the die is closed used by it, top
Mould 1 compresses the effect of aluminium profiles core 2, so forms complete die casting die cavity.The deepest ring when aluminum liquid filling type, at wheel thermal center
Shape is drawn material and is cast molding.
During molding, whole blank is retained on backform 1, and when push rod ejects, the jump ring 5 on aluminium profiles core 2 is along with ejecting force
Effect departs from backform 1, completes the process of blank break away from moulds.At this moment aluminium profiles core 2 combines together with cast blank, on aluminium profiles core
Wedge metal 6 ring rubber hand hammer beat gently and just wedge metal ring 6 can be departed from wheel blanks, blank at this moment can turn
Entering next operation, the operation such as heat treatment, machining completes.
