Abstract

The invention discloses a low-pressure casting mold structure for an aluminum alloy hub, which comprises an upper mold, a lower mold and a side mold. The region formed in the mutual boundary of the upper mold, the lower mold and the side mold is a thermal node of the casting hub, the lower mold is provided with pouring heads; the pouring heads are arranged at the side of the lower mold and are directly communicated with the thermal node, the two pouring heads are symmetrically arranged at the side of the lower mold, and the pouring heads are arranged at the side of the lower mold which is nearest to the thermal node. To further improve the technical effect, the middle of the lower mold is provided with a central pouring head. Owning to the adopted technical improving measure of the invention, the thermal node can feed with the help of the pouring heads, thus avoiding a shrink hole. The casting mold structure can be widely applied to the low-pressure casting mold.

Description

The low pressure casting mould structure of aluminium alloy wheel hub
Technical field
The present invention relates to a kind of low pressure casting mould structure of aluminium alloy wheel hub.
Background technology
The mould of casting of automobile aluminium alloy wheel hub generally is divided into compression casting hub mold and gravity casting hub mould.And the mould of low pressure casting wheel hub, the mould structure of the single cast gate at present main employing center, as shown in Figure 1, the mould of traditional low pressure casting wheel hub, generally comprise patrix 1, counterdie 2, side form 3 parts such as grade, described patrix 1, after counterdie 2 and side form 3 combinations, the casting mold cavity of casting hub is treated in formation, prior art mainly is provided with the single cast gate in center at the central part of counterdie, and aluminium alloy solution process stalk is under the pressure of burner hearth, from cast gate A charging, monolateral side at die cavity looks up, order by A-B-C-D-E-F is filled, and solidifies order and is undertaken by the F-E-D-C-B-A order, and wherein the D point is the thermal center point.Described thermal center point, it is the formed zone of intersection of described patrix 1, counterdie 2 and 3 three moulds of side form, from institute's casting hub, the boundary intermediate location between spoke that described thermal center point D is a wheel hub and the wheel net, thickness of aluminum alloy herein is bigger, and the thickness of position C, E is little, the speed of often solidifying is fast, causes being difficult to obtain qualified cast sturcture in position D feeding difficulty, generally can produce shrinkage cavity, loose, thereby the casting difficult point of aluminium alloy wheel hub is also just at this position D.
Summary of the invention
At the deficiency in the existing conventional art, a kind of low pressure casting mould structure of the special proposition of the present invention utilizes this low pressure casting mould structure in the process of the automotive hub of making, and running channel is wide, the temperature of mould is more even, efficiently solves the problem that thermal center point position can't feeding.
The present invention has adopted following technical scheme:
The aluminium alloy wheel hub low pressure casting mould structure comprises patrix 1, counterdie 2 and side form 3, and the zone that described patrix 1, counterdie 2 and side form 3 common positions, boundary form is the thermal center point D of casting hub, and described counterdie 2 is provided with cast gate A; It is characterized in that: described cast gate A is arranged on the side of described counterdie 2 and directly is communicated with described thermal center point D, and described cast gate A has two and be distributed in the side of described counterdie 2.
In order further to improve technique effect, described cast gate A is arranged on the lateral location with the nearest described counterdie 2 of described thermal center point D.
In order further to improve technique effect, described counterdie 2 is provided with the described cast gate A more than three or three, and described cast gate A is distributed in the lateral location of described counterdie 2.
In order further to improve technique effect, the central part of described counterdie 2 also is provided with central cast gate A1.
The technological improvement measure that the present invention taked can reach following beneficial effect:
1. the side at described counterdie 2 is symmetrical arranged plural cast gate, and the aluminium water in the mold cavity is flowed along both direction, and running channel is wide, and the temperature of mould is more even.
2. casting solidification process also carries out respectively along both direction, thereby make casting process not only stable, and thermal center point D directly closely directly is communicated with cast gate, owing to cast gate temperature of aluminum liquid height, make thermal center point D avoid producing shrinkage cavity well by means of the cast gate feeding.
Because the present invention has above-mentioned advantage, can be widely used in the units of low-pressure casting automobile hub mold.
Description of drawings
Fig. 1 is the assembling schematic diagram of conventional low casting of automobile hub mould;
Fig. 2 is a cavity structure schematic diagram of using the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing, further specify application the specific embodiment of the present invention:
As shown in Figure 2, the aluminium alloy wheel hub low pressure casting mould structure, comprise patrix 1, counterdie 2 and side form 3, the zone that described patrix 1, counterdie 2 and side form 3 common positions, boundary form is the thermal center point D of casting hub, at the side of described counterdie 2 and the position that directly is communicated with described thermal center point D described cast gate A is set, described cast gate A has two and be symmetrically distributed in the side of described counterdie 2.Certainly as equivalent, two described cast gate A also can asymmetricly be distributed in the side of described counterdie 2.The side of described counterdie 2 as shown in Figure 2, is positioned at the following of described counterdie 2 and close outer side edges edge.Described thermal center point D position die cavity generally forms the boundary intermediate location of spoke with the wheel net of wheel hub.In when casting, from half location view of die cavity, after aluminium water enters from cast gate, along A-D-E-F and the A-D-C-B-G-H both direction filling die cavity that advances; When solidifying, progressively solidify along F-E-D-A and C-B-G-H direction.Wherein, described H point position is the rising head position of wheel hub, is used for the wheel hub that H is ordered is given feeding.Correspondingly, the aluminium water that enters from another cast gate with this cast gate symmetry also enters die cavity and in this way by same direction consecutive solidification.Under mode like this, the influence that the solid effect of the aluminium water-setting of described thermal center point D is not ordered by the less relatively E of its two side runner, C, because cast gate temperature of aluminum liquid height, the aluminium water of described thermal center point D can pass through the direct feeding of cast gate A when solidifying, and avoids producing shrinkage cavity at described thermal center point D.
In the above-described embodiments, another cast gate A1 can also be set at the central part of described counterdie 2, thereby the wheel hub of H point die cavity is given feeding.
In the above-described embodiments, if the stalk of foundry machinery has corresponding setting, described cast gate A also can three or is distributed in the side (not drawing among the figure) of described counterdie 2 more than it, thus stable more, cast aluminum water and feeding in die cavity equably.
