Description

A kind of aluminum-alloy wheel gravity-assist pouring leakproof constructed of aluminium

Technical field

The utility model belongs to the gravity casting die field, relates to the aluminum-alloy wheel gravity casting die, especially a kind of gravity casting die running gate system leakproof constructed of aluminium.

Background technology

At present, the domestic production aluminum-alloy wheel often adopts gravitational casting and two kinds of methods of low pressure casting.Often adopt two-opening type to divide mould to its structure of gravitational casting.Wherein, running gate system is usually located at the limit and touches the side.Traditional gravity mould running gate system partly is made up of sprue 1, cross gate 2, ingate 3 etc. usually.Because of being subjected to temperatures involved, limit mould in the production of aluminium wheel hub produces distortion, and bigger in limit mould cross gate 2 peripheral slits, produce overlap, in addition, overlap sticks on the die joint, and the cleaning trouble influences matched moulds, and production efficiency and stock utilization are all had very big adverse effect.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of gravity casting die running gate system leakproof constructed of aluminium is provided.It can effectively reduce the generation of blank overlap, improves the utilization rate of material.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of aluminum-alloy wheel gravity-assist pouring leakproof constructed of aluminium is made of sprue 1, cross gate 2, ingate 3 and anti-bakie 4.Offering anti-bakie at the cross gate periphery is characterized in that:

(1) offer the anti-bakie of semicircle that radius is R2 at the cross gate periphery, anti-bakie two ends are communicated with the cross gate die cavity.

(2) two limit mould matched moulds rear defence bakies form the annulus that radius is R2.

Advantage of the present utility model and beneficial effect are:

1, the optimal design of this running gate system is the part change on traditional gravity casting die running gate system, be the semicircle annular groove of R2 and be communicated with by the processing radius with cross gate, form an annular housing at the running channel periphery, anti-bakie also can be filled simultaneously when injecting aluminium liquid, and, the cross gate periphery is shut anti-leak-stopping aluminium because of the narrow quick cooled and solidified in space.

2, the utility model can effectively solve the problem that aluminium is leaked in the cross gate generation in the processing of aluminum vehicle wheel gravitational casting, and it is simple in structure, and is easy to process, and it is low to optimize cost, helps enhancing productivity and economizing on resources.

The specific embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of aluminum-alloy wheel gravity-assist pouring leakproof constructed of aluminium, referring to Fig. 1 and Fig. 2, constitute by sprue 1, cross gate 2, ingate 3 and anti-bakie 4, sprue 1 links to each other with cross gate 2, and cross gate 2 links to each other with ingate 3, and cross gate 2 circumferential distribution have anti-bakie 4, anti-bakie 4 two ends are communicated with cross gate 2, also can be full of simultaneously leakproof grooved chamber when aluminium liquid enters cross gate, the aluminium liquid in the anti-bakie cools off fast and forms a confining bed, prevents that the cross gate periphery from leaking aluminium.

Claims (1)

1. an aluminum-alloy wheel gravity-assist pouring leakproof constructed of aluminium is made of sprue (1), cross gate (2), ingate (3) and anti-bakie (4), offers anti-bakie at the cross gate periphery and it is characterized in that:

(1) offer the anti-bakie of semicircle that radius is R2 at the cross gate periphery, anti-bakie two ends are communicated with the cross gate die cavity,

(2) two limit mould matched moulds rear defence bakies form the annulus that radius is R2.
