Description
Technical field
The present invention relates to a kind of mould, more particularly to a kind of aluminum alloy hub casting die.
Background technology
At present, most wheel hubs use aluminium alloy wheel hub, and its manufacture method has three kinds：Gravitational casting, forging and low pressure
Hot investment casting, wherein gravitational casting are to use gravity to aluminium alloy solution to be cast in mould, and after molding, Jing lathes process polishing
Production can be completed.As its manufacture process is simple, be not required to precision casting process, low cost and production efficiency it is high and by most factories
Family adopts.But, in process of production, the method for this aluminium alloy casting wheel hub, the hub cast in mould is level
Place, in other words, the sagittal plane of wheel hub is horizontal positioned, therefore, the mould of wheel hub is by upper die and lower die and side form group
Into there is wheel hub one end of disc to be located at the bottom of mould, and other end free end is located at the top of mould, and this free end
Edge side riser will be set, due to this edge thinner thickness, be the position of last cooled and solidified again, therefore, water-cooled
Be quickly easy to wheel hub edge produce the casting flaw such as bubble and shrinkage porosite；Also, foundry goods is de- in this case
It is easy to become ovalisation in the wheel rim of free end after mould.
The content of the invention
The technical problem to be solved in the present invention is the present situation for prior art, there is provided a kind of casting aluminium alloy wheel hub mould
Tool, can make foundry goods avoid the casting flaws such as bubble and shrinkage porosite occur in edge.
The present invention solve the technical scheme that adopted of above-mentioned technical problem for：A kind of aluminum alloy hub casting die, including
Backform, bed die and multiple side forms, the backform, bed die and multiple side forms are formed for shaping the die cavity of wheel hub, in the bed die
It is provided with cooling water channel, it is characterised in that：The bottom of each side form is provided with guide rail, described each side form and a slip cylinder
Connection, is used for shaping to slide on the side upper end of wheel hub on the side form being provided with a slide plate, uses on the slide plate and the side form
In the sided seamless laminating of shaping wheel hub, the back of the side form offers mounting groove, the installation groove location and the slide plate position
Put corresponding, in the mounting groove, be provided with a promotion cylinder, the output shaft of the promotion cylinder is connected with the slide plate, the mounting groove
Bottom land be provided with multiple fog-spray nozzles, the fog-spray nozzle is connected with a spraying system.
Used as improvement, the bottom land of the mounting groove is provided with multiple jet thrusts, and the jet thrust is intersected with the fog-spray nozzle
Arrangement, multiple rows of jet thrust are connected with a gas ejecting system.By arranging gas ejecting system, realize dual to foundry goods jet and spraying
Cooling.
Improve again, the set-up mode of the slide plate there are two kinds, and the first is, be used for shaping the side of wheel hub on the side form
On laterally offer the chute of insertion, offer draw-in groove on two side walls up and down of the chute, on the upper and lower two sides of the slide plate
The card article being adapted with the draw-in groove is formed with, the slide plate is slidedly arranged in the chute, the slide plate is constituted to be used on the side form
In shaping wheel hub side.This ensure that on the surface of slide plate and the side form for shape wheel hub side on same surface
It is interior, be conducive to wheel hub Forming Quality.
Second is that the slide plate is fitted in is used for the side for shaping wheel hub, the groove of the mounting groove on the side form
Bottom offers bar hole, and the connection connecting rod for promoting cylinder and the slide plate is arranged in the bar hole.This mode is tied
Structure is simple, it is desirable to slide plate thinner thickness.
Compared with prior art, it is an advantage of the current invention that：The present invention in cooling procedure, first with water-cooled under foundry goods
End thicker position is first cooled down, then in the presence of slip cylinder, opens side form, promotes cylinder action, slide plate to slide, mounting groove bottom
The fog-spray nozzle in portion exposes alignment foundry goods, and spraying system carries out water smoke cooling to the relatively thin position in foundry goods upper end so that foundry goods is originally most
The position of the last cooled and solidified in upper end is also cooled down simultaneously, therefore, it is to avoid bubble and shrinkage porosite are produced at the upper end-face edge of wheel hub
Etc. casting flaw；Also, in the case where foundry goods is topmost adequately cooled solidification, the wheel rim at this is just difficult after demoulding
There is oval phenomenon.
Description of the drawings
Fig. 1 is the structural representation of aluminum alloy hub casting die in the embodiment of the present invention；
Fig. 2 is the structural representation (chute insertion) of side form in the embodiment of the present invention；
Fig. 3 is the back structures schematic diagram of Fig. 2 side forms；
Fig. 4 is the structural representation (chute not insertion) of side form in the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 3, the aluminum alloy hub casting die in this enforcement, including backform 1, bed die 3, multiple side forms 2,
Guide rail 4, slip cylinder, promotion cylinder 5, fog-spray nozzle 71, spraying system, jet thrust 72 and gas ejecting system.Preferably, the number of side form 2
For 4.
Wherein, backform 1, bed die 3 and multiple side forms 2 are formed for shaping the die cavity of wheel hub 6, are provided with cooling in bed die 3
Water channel, the bottom of each side form 2 are provided with guide rail 4, and each side form 2 is connected with a slip cylinder, are used for shaping wheel on the side form 2
Slide on the side upper end of hub 6 and be provided with a slide plate 8, be used to shape the sided seamless patch of wheel hub on the slide plate 8 and the side form 2
Close, the back of the side form 2 offers mounting groove 22, and 22 position of mounting groove is corresponding with 8 position of the slide plate, the installation
A promotion cylinder 5 is provided with groove 22, the output shaft of the promotion cylinder 5 is connected with the slide plate 8, the bottom land of the mounting groove 22 is arranged
There are multiple fog-spray nozzles 71, the fog-spray nozzle 71 is connected with a spraying system.Further, the bottom land of mounting groove 22 is provided with multiple sprays
Gas head 72, the jet thrust 72 and 71 arranged crosswise of the fog-spray nozzle, multiple rows of jet thrust 72 are connected with a gas ejecting system.It is logical
