Abstract
A low-pressure casting die for an aluminum alloy wheel is composed of an upper die plate, an upper die, a lower die and a lower die plate. Side dies are arranged between the upper die plate and the lower die plate. Inclined pressing side cooperation is adopted in the upper die and the side dies, aluminum leaking clearances caused by side dies, fault dies and the like are eliminated through attachment of long inclined faces, and therefore the problem of trimming of the aluminum alloy wheel is solved. When a lower die structure and an upper die mechanism are matched, the lower die is inserted in the upper die, trimming is prevented from happening to the matching face of the upper die and the lower die, and therefore the trimming defect of the cast wheel is eliminated, and the use rate of raw materials is increased.
Description
Technical field
The invention belongs to mould applications, further, relate to a kind of low-pressure casting die of aluminium alloy wheel.
Background technology
The most blank of aluminum-alloy wheel of current domestic production is with a large amount of overlap, raw-material utilization rate is had a greatly reduced quality thus, the operation of the remelting recycling of rim charge like flying not only increases energy resource consumption, production cost, also cause the lot of unstable factor of green state simultaneously, cause blank at the automatic operational difficulties of inter process, especially the pickup blank that robot cannot be stable, causes whole production line to realize fully automatic operation.
Stronger casting pressure can be produced in low pressure casting cavity filling process, aluminium liquid in extrusion die passes through gap overflow, in low pressure casting process, mould is in the condition of high temperature, mould also can therefore and produce distortion, mating surface gap increases, occur mismatch phenomenon in die assembly, aluminium liquid is outflowed and forms burr.
Fig. 1 is the way of contact of patrix and limit mould plane in aluminum-alloy wheel casting mould in prior art. as shown in Figure 1: when mould matched moulds, patrix and limit mould contact with each other, cause gap excessive, not for stopping that aluminium hydrorrhea goes out to create obstruction condition, aluminium liquid easily overflows from patrix 1 and the mild mating surface 7 in the middle of limit mould 3 thus, causes the generation of overlap.
Fig. 2 is the way of contact of patrix and counterdie plane in aluminum-alloy wheel casting mould in prior art. as shown in Figure 2: when mould matched moulds, patrix and limit mould contact with each other, cause gap excessive, not for stopping that aluminium hydrorrhea goes out to create obstruction condition, aluminium liquid easily overflows from patrix 1 and the mild mating surface 8 in the middle of counterdie 4 thus, causes the generation of overlap.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of low-pressure casting die of aluminium alloy wheel.
The technical solution adopted for the present invention to solve the technical problems is:
Low-pressure casting die of aluminium alloy wheel of the present invention, described mould comprises cope match-plate pattern, patrix, Bian Mo, counterdie, lower bolster, patrix and cope match-plate pattern with bolts, counterdie and lower bolster with bolts, its patrix and counterdie zone line lay polylith limit mould, be fitted to each other between limit mould and limit mould, and the mould place of being fitted to each other, limit leaves expansion headspace.
Patrix and limit mould closely cooperate, and the face of being fitted to each other is inclined-plane.
Counterdie and patrix closely cooperate, and the face of being fitted to each other is male and fomale(M&F).
Further:
Between upper mould and limit mould, inserting the degree of depth of patrix by counterdie during upper die and lower die contact is 2-7mm, and its counterdie mating surface is convex surface, and patrix mating surface is concave surface.
Polylith limit mould is four pieces and is fitted to each other, and mating surface adopts 45 ° of faces to assemble.
The thermal expansion headspace of 0.1-0.3mm is had between the limit mould be fitted to each other.
Advantage of the present invention and good effect are:
In low-pressure casting die of aluminium alloy wheel of the present invention, owing to employing patrix and the close-fitting inclined-plane of Bian Mo and patrix and the close-fitting male and fomale(M&F) of counterdie, overcome the overlap of aluminum-alloy wheel in casting process to generate, result in the situation that the consumption decreasing raw material controls energy waste, result in decrease and remove overlap operation lifting integrated artistic flow process and benefit, result in and decrease because rejecting again injuring finished product of causing of overlap, when overcoming wheel automated production, be unfavorable for the technical bottleneck of mechanical device automatic Picking.

Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
As shown in Figure 3, low-pressure casting die of aluminium alloy wheel structure of the present invention, comprise cope match-plate pattern 1, patrix 2, limit mould 3, counterdie 4, lower bolster 5, cope match-plate pattern and patrix are bolted, it is counterdie below patrix, counterdie and lower bolster are bolted, the patrix between cope match-plate pattern and lower bolster and be furnished with limit mould between counterdie.
As shown in Figure 4, low-pressure casting die of aluminium alloy wheel structure of the present invention, patrix and limit mould adopt the limit fit system that baroclines, and form the face that fits tightly 6 of inclination;
As shown in Figure 5, low-pressure casting die of aluminium alloy wheel structure of the present invention, patrix and counterdie mating surface place adopt counterdie to insert the structure of patrix, form staggered seamless cooperation male and fomale(M&F), wherein counterdie contact surface is convex surface, and patrix contact surface is concave surface, and counterdie recessed portion is die cavity.
Patrix and counterdie zone line are furnished with four pieces of limit moulds and are fitted to each other, and mating surface angle is 45 °, limit mould one side milling 0.1mm, so the bonded to each other but thermal expansion headspace that can leave 0.2mm in the face that is fitted to each other when matched moulds does not expand is avoided producing mismatch.
Method of work of the present invention is as follows:
Patrix and limit mould are after matched moulds, and patrix wheel rim inclined-plane place is pressed on wheel rim place on the mould of limit, two contact surfaces fitting together tightly.The initiating terminal of inclined plane, lower than end end, causes aluminium liquid cannot overflow from inclined-plane.Begin through sprue bush after mold-locked and inject aluminium liquid to mold cavity, then cooling forming, casts out the aluminum-alloy wheel of non-trimming.
Patrix and counterdie are after matched moulds, and counterdie and patrix mating surface insert patrix 5mm by counterdie, and the mating surface of patrix and counterdie is interlaced with each other, cause aluminium liquid cannot overflow from male and fomale(M&F).After mold-locked, inject aluminium liquid by sprue bush to mold cavity, then cooling forming, casts out non-trimming aluminum-alloy wheel.
