Abstract
The invention relates to a side die for solving the bottom deformation of a wheel rim. The side die comprises a side die and is characterized in that a ring-shaped boss is arranged at the position, which corresponds to the bottom part of the wheel rim, on the side die. The side die has the advantages that the structure is simple and ingenious, the wall thickness of the bottom part of the wheel rim can be consistent with the wall thickness of the other parts, the difficulty of rim deformation due to non-uniform wall-thickness distribution is solved, the mechanical performance of a wheel is improved and the quality and the qualification rate of products are improved.
Description
Technical field
The present invention relates to a kind of wheel die, specifically a kind of side form that solves rim for automobile wheel deformation of bottom.
Background technology
The aluminum-alloy wheel that has a kind of gravitational casting, its mould is mainly comprised of cope match-plate pattern, side form and lower bolster, and cope match-plate pattern is arranged on lower bolster top, and side form is arranged on lower bolster and cope match-plate pattern is peripheral, forms wheel die cavity between cope match-plate pattern, lower bolster and side form.In prior art, on side form, the position of corresponding rim for automobile wheel bottom is made into circular arc, when gravity-assist pouring wheel, causes the wall thickness (being about 13.5mm) of rim for automobile wheel bottom large more than the wall thickness (being about 7mm) at other positions of wheel rim.Serious inhomogeneous the causing of this Thickness Distribution easily produces thermal center at rim for automobile wheel, makes ambient stress skewness, and the problem that easily deforms has had a strong impact on the mechanical performance of wheel, causes the qualification rate low (generally less than 20%) of product.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of side form that solves rim for automobile wheel deformation of bottom is provided, its simple and ingenious structure, can make the wall thickness of rim for automobile wheel bottom consistent with the wall thickness at other positions, solved the rim deformation difficult problem causing because Thickness Distribution is inhomogeneous, improve the mechanical performance of wheel, improved quality and the qualification rate of product.
According to technical scheme provided by the invention: solve the side form of rim for automobile wheel deformation of bottom, comprise side form, it is characterized in that: on described side form, the position of corresponding rim for automobile wheel bottom is provided with annular boss.
As a further improvement on the present invention, the cross sectional shape of described annular boss is trapezoidal.
As a further improvement on the present invention, the height of described annular boss is 7 ~ 8mm, and the width at annular boss top is 15 ~ 17mm.
compared with prior art, advantage is in the present invention:simple and ingenious structure of the present invention, can make the wall thickness of rim for automobile wheel bottom consistent with the wall thickness at other positions, has solved the rim deformation difficult problem causing because Thickness Distribution is inhomogeneous, has improved the mechanical performance of wheel, has improved quality and the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the present invention and cope match-plate pattern, lower bolster fit applications situation schematic diagram.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: side form 1 and cope match-plate pattern 4, the lower bolster 5 of the solution rim for automobile wheel deformation of bottom in embodiment are used in conjunction with, and form wheel die cavity 6.The mould of triumphant return D6 wheel 2 of take is example, as shown in Figure 1 and Figure 2, on described side form 1, the position of corresponding wheel 2 rim base 2a is provided with annular boss 3, and the cross sectional shape of described annular boss 3 is trapezoidal, the height h of annular boss 3 is 7.5mm, and the width d at annular boss 3 tops is 16.3mm.
Before not adopting the present invention, after triumphant return D6 wheel 2 moulding by casting, the wall thickness of wheel 2 rim base 2a is generally 13.3mm, and the wall thickness at other positions is generally 7.3mm, and Thickness Distribution is seriously inhomogeneous, and qualification rate is extremely low.And after employing the present invention, the wall thickness of wheel 2 rim base 2a is improved as 6mm, basically identical with the wall thickness at other positions, improved the situation that rim base 2a is out of shape, more than improving the qualification rate to 95% of product.
Claims (3)
1. solve the side form of rim for automobile wheel deformation of bottom, comprise side form (1), it is characterized in that: the position of upper corresponding wheel (2) rim base (2a) of described side form (1) is provided with annular boss (3).
