Description
Technical field
The present invention relates to the casting mould of aluminium alloy low pressure wheel hub, particularly the side mould structure of mould.
Background technology
Existing aluminium alloy wheel hub 9; As shown in Figure 1; Its low pressure mfg. moulding die comprises patrix 1, counterdie 2, left side mould 3, right side mould 4; In the space that said patrix 1, counterdie 2, left side mould 3, right side mould 4 are surrounded,, treat that its cooling back forms wheel hub 9 through being arranged on the inside aluminium alloy water of casting fusions of cast gate 61 on the said counterdie 2; Patrix 1 is provided with cooling duct (5,7) with counterdie 2, and said patrix 1 is provided with branch flow cone 6.But the mould of this kind common structure; In low pressure casting process, often have such situation, thereby the wheel rim top 9A of wheel hub 9 is because relatively thin cooling is very fast, and the bottom 9B of wheel rim there be very slow that a very big thermal center causes cooling off; Cause whole casting cycle very long; Casting character is defective, is that the intensity of cooling of mould is also inhomogeneous inadequately with regard to its reason, and the side mold of conventional molds (3,4) is whole; If (temperature at the position that intensity of cooling of (3,4) part can need not be cooled off side form (3,4) top reduces, and causes the defectives such as cold shut shrinkage porosite of foundry goods directly to strengthen said side form.For example application number is 201020120558.0 utility model patent, and it has disclosed the low pressure casting hub mold, comprises upper die and lower die and side form; After described upper die and lower die and the side form combination; The casting mold cavity of casting hub is treated in formation, and said counterdie is provided with the sprue gate, and the zone that the position, boundary of said upper die and lower die and side form forms is the thermal center point of casting hub; The inboard of said side form is positioned at thermal center point place and is inlaid with air ring; Be provided with cooling water channel in the described air ring, said cooling water channel is provided with and is in communication with the outside inlet channel and water outlet, is positioned at the profile and the profile phase coupling of treating this place on the cast wheel hub of casting mold cavity one side on the said air ring.Can guarantee the integrality of die cavity; In again can the process of setting after cast; In air ring, pour cooling water, accelerate the cooling velocity of thermal center point, thereby avoid that the wheel hub spray produces shrinkage cavity, defective such as loosen; But the side form of this structure can constitute influence to non-thermal center point position inevitably and particularly the top 9A of wheel rim constituted negative effect in water-cooled process.
Summary of the invention
In order to improve the quality of production, the rate of reducing the number of rejects and seconds and production cycle, the structure of further improving side mold is a focus of the present invention.For this reason, the present invention proposes a kind of side form structure of low pressure hub mold, it is characterized in that, said side form comprises the last side form and following side form of butt joint up and down, on the web of said side form down, cooling water cavity is set.
According to said structure, change the side mold of casting mould the last side form and the following side form of butt joint up and down into, reduced the temperature transmission between last side form and the following side form at least; Thereby cooling water cavity is set on the web of secondly said side form down can in said side form down, leads to cooling water; Make the basic and said last side form of cooling velocity of said following side form consistent; And then make the top 9A of wheel hub consistent with the cooling velocity of lower part 9B; Shortened whole casting cycle greatly, the casting character qualification rate is promoted.
Further technical scheme can also be, said on the lower surface of web of side form be provided with heat insulation groove.The long-pending minimizing of direct contact surface that said heat insulation groove can make up and down butt joint between the said web of going up side form and following side form, thus the heat transmission between said upward side form and the following side form further reduced.
Further technical scheme can also be, is provided with positioning pin column between the gusset of said upward side form and following side form.Through said positioning pin column, can make between the said gusset of going up side form and following side form contraposition accurately and assembling fast.
Because the present invention has These characteristics and advantage, can be applied in the mould product of low pressure casting aluminum alloy wheel hub.

The specific embodiment
Be described further below in conjunction with the said upward side form and the said structure of side form down of accompanying drawing the casting mould of application technical scheme of the present invention.
Arrive shown in Figure 5 like Fig. 2; The low pressure mfg. moulding die comprises patrix 1, counterdie 2, left side mould 3, right side mould 4; In the die cavity that said patrix 1, counterdie 2, left side mould 3, right side mould 4 are surrounded,, treat that its cooling back forms wheel hub 9 through being arranged on the inside aluminium alloy water of casting fusions of cast gate 61 on the said counterdie 2; Said patrix 1 is provided with cooling duct (5,7) with counterdie 2, and said patrix 1 is provided with branch flow cone 6.
Wherein, said left side mould 3 is docked up and down with following side form 32 by last side form 31 to be formed, and said right side mould 4 is docked up and down with following side form 42 by last side form 41 to be formed.Said left side mould 3 is basic identical with the structure of said right side mould 4.
As shown in Figures 2 and 3, the said side form 31 of going up comprises web 311 and gusset 312, on the lower surface of the web of side form 31 heat insulation groove 83 is set on said, and the said gusset of going up side form 31 is provided with positioning pin column 33 and bolt hole 34; The degree of depth of wherein said heat insulation groove 83 is between 0.5 millimeter to 1.5 millimeters.Secondly according to the purposes of this structure, said heat insulation groove 83 is positioned at the said upward central part of the lower surface of the web of side form 31, and said at least heat insulation groove 83 can not be communicated with the die cavity that holds aluminium water.
Like Fig. 2 and shown in Figure 4; Said side form 32 down comprises web 321 and gusset 322; 81 places, web 321 positions at said down side form 32 are provided with cooling water cavity 82, and the said gusset 322 of side form 32 down is provided with locating hole 331 and the bolt hole 35 adaptive with the said positioning pin column of going up side form 31 33.Wherein can be at first process deep groove, form said cooling water cavity 82 thereby the aperture position of said dark groove is sealed with the mode of welding with cover plate again at said 81 places, web 321 positions of side form 32 down.Paired aqueduct 8 is communicated with said cooling water cavity 82.
As shown in Figure 5, said left side mould 3 is docked up and down with following side form 32 by said upward side form 31 to be formed, and wherein cooling water is introduced or drawn from the paired said aqueduct 8 that is positioned between the gusset (312,322).Cooling water cavity 82 on the said down side form 32 and said said heat insulation groove corresponding setting 83 about of going up on the side form 31, like this just can reduce as possible said between side form 31 and the following side form 32 the heat transmission and cause heat affecting.Said going up between side form 31 and the following side form 32 not only located through said positioning pin column 33, but also gives fastening through bolt passing through bolt hole (34,35).
After with the casting mould assembled; In mold cavity, press injection aluminium water through cast gate 61; At the cooling water of mould being given also in said down side form 32, pass in air-cooled design temperature; Control said side form (31,41) and the said temperature of side form (32,42) down of going up, make order condensation of aluminium water and cooling fast, improve casting speed and end product quality.
