Description
Technical field
The present invention relates to a kind of casting mould of metal wheel hub, the casting mould can improve due to side form temperature distortion
There is the problem of overlap defect in caused casting afterwards.
Background technology
In metal wheel hub casting process, high temperature aluminium liquid is injected into the cast moulding being formed between upper die and lower die and side form
Intracavitary.Under high temperature action, the top of the side form and the inward-facing generation thermal expansion deformation of coupling collar of the upper mould cooperation, from
And the cooperation of the combination anchor ring and the upper mould is had influence on, cause to be formed between the combination anchor ring of the side form and the upper mould
Deformation gap.In cavity filling process, aluminium liquid is overflowed at the deformation gap, is caused to leak aluminium, is formed obvious overlap.So, not only
Hub cast shaping can be caused bad, influence follow-up machining processes, but also damage can be caused to equipment or even causes personnel
Injury.How appropriate thermal distortion compensation is carried out to the side form into a great problem of industry.According to traditional solution party
Case, as shown in figure 1,10 whole sections of L relative datums circular arcs 2 of combination anchor ring the side form 1（The benchmark circular arc 2 represents described
Theoretical shape before being biased with reference to anchor ring 10）Outwardly biased amendment, left end A and right-hand member B and the base of the combination anchor ring 10
The offset distance of director circle arc is zero, and the offset distance of the combination anchor ring 10 and the benchmark circular arc is gradual from left end A and right-hand member B to middle-end C
Increase.Certain improvement has although been obtained after being biased amendment to the combination anchor ring 10, the problem of overlap, but still not
It is too preferable.
The content of the invention
In view of the above-mentioned problems, research staff continues to study to the structure of side form.Institute particularly to thermal deformation occurs
Side form is stated repeatedly observe and find after analyzing, during casting, the middle section position of the combination anchor ring of the side form
Mould temperature is relatively high and thermal expansion deformation occurs.And due to the influence of the factors such as wall thickness, the left fragment position of combination anchor ring and
The mould temperature relatively bottom of right fragment position, substantially will not occur thermal expansion deformation and thermal expansion deformation is very small.As can be seen here,
The side form can make left and right two sections of faying faces with stage casing faying face not on same circular arc with reference to anchor ring because of thermal expansion.
In consideration of it, the present invention proposes a kind of casting mould of metal wheel hub, including the upper die and lower die split up and down, and
The side form being arranged between the upper die and lower die, the cast moulding of the wheel hub is formed between the upper die and lower die and side form
Chamber, the top of the side form is provided with can be with the upper combination anchor ring of casting mold cavity described in the upper mould fitted seal；Its feature
It is, in terms of radial cross-section, the upper combination anchor ring is divided into left section of upper faying face, right section of upper faying face and is connected in described
Faying face on stage casing between left section of upper faying face, right section of upper faying face；Described left section upper faying face, right section of upper faying face are located at
On same upper benchmark circular arc, on the stage casing faying face outwardly away from the upper benchmark circular arc, on the stage casing faying face and
Offset distance between the upper benchmark circular arc becomes larger from left and right both ends to centre.
Wherein, the radial cross-section refers to along transversal obtained by the direction cutting side form of the side form open and close movement
Face.
Wherein, described left section upper faying face, right section of upper faying face are located on same upper benchmark circular arc, are tied on the stage casing
Conjunction, which faces out, deviates the upper benchmark circular arc, and the offset distance on the stage casing between faying face and the upper benchmark circular arc is from left and right
Both ends become larger to centre.Features described above defines the shape of the upper combination anchor ring.Described left section upper faying face, on right section
The offset distance of faying face and the upper benchmark circular arc is zero, and exist on the stage casing between faying face and the upper benchmark circular arc from
The offset distance that the right and left becomes larger to centre.And maximum offset distance according to the size of the side form, the swell increment of manufacture material with
And mould temperature in casting process determines.It should be noted that " outside " is to away from the direction of the casting mold cavity.
Wherein, the upper benchmark circular arc is the reference data that the upper combination anchor ring is biased amendment.The body in reality
The benchmark theory shape before amendment now is biased for the upper combination anchor ring, can also be embodied as and described left section upper faying face, the right side
The overlapping reference circular arc of faying face in section.
According to above-mentioned technical proposal it can be found that to faying face, right section of upper faying face on left section of the upper combination anchor ring
And on stage casing after faying face makees different, appropriate biasing amendment, thermal distortion compensation effectively can be carried out to the side form, avoided
Or reduce the hub cast and overlap defect occur, improve the qualification rate of the hub cast.
Further technical scheme is also possible that the bottom of the side form is provided with can be with the lower mould fitted seal institute
State the lower combination anchor ring of casting mold cavity；In terms of radial cross-section, the lower combination anchor ring is divided into left section of lower faying face, tied under right section
Faying face under conjunction face and the stage casing being connected between the left section of lower faying face, right section of lower faying face；Combined under described left section
Face, right section of lower faying face are located on same lower benchmark circular arc, under the stage casing faying face outwardly away from the lower benchmark circular arc,
Offset distance under the stage casing between faying face and the lower benchmark circular arc becomes larger from left and right both ends to centre.Wherein, it is described
Lower combination anchor ring has similar architectural feature and function with the upper coupling collar face, is not repeated to discuss herein.
Further technical scheme be also possible that the arc length of described left section upper faying face, right section of upper faying face for 40~
150mm.Similarly, further, the left section of lower faying face, the arc length of right section of lower faying face are 40~150mm.Wherein, it is described
Left section of upper faying face, right section of upper faying face, left section of lower faying face, the specific arc length of right section of lower faying face are according to the chi of the side form
Depending on very little.
Because the present invention has These characteristics and advantage, may apply to for this on casting mould of metal wheel hub.
