Abstract
The utility model discloses a hub die structure to big centre bore, including last mould, set up the last mold core in last mould to and die block, upward shape moulding chamber behind mould and the die block compound die, the die block corresponds the position of foundry goods centre bore and makes recessed formula, goes up the mould and go up the mold core position together to sinking, to form oblique ascending water conservancy diversion passageway. The beneficial effect of the utility model: be recessed formula with the die block design, aluminium water will be more steady filling the type in -process, reduce aluminium water in the book gas phenomenon of in -process that flows. To go up the mould and go up the mold core and make the formula, and can make the mould and the area of contact of runner further strengthen to reach and solidify the faster thermal mesh of foundry goods of taking away of in -process at the foundry goods.
Description
Technical field
The utility model is related to technical field of mold, a kind of hub mold structure for Large central aperture.
Background technology
Statement in this part merely provides the background information relevant with the utility model disclosure thereby increases and it is possible to not
Constitute prior art.
With the continuous development of wheel hub industry, the occupation rate of market of aluminium alloy wheel hub progressively expands, and extends further
To big bus wheel hub.The front and back wheel of big bus wheel hub all has the feature of Large central aperture, still continues to use traditional mould for this feature
Lamps structure cannot meet the high performance requirements of big bus wheel.
Therefore prior art has much room for improvement and develops.
Utility model content
The technical problems to be solved in the utility model is to provide one kind more steadily will to reduce aluminium water and exist in cavity filling process
The hub mold structure for Large central aperture of flowing.
Technical solution of the present utility model is: a kind of hub mold structure for Large central aperture, including upper mould, if
Put the upper mold core in upper mould, and bed die, form die cavity after upper mould and bed die matched moulds；The position of the corresponding foundry goods centre bore of bed die
Make up concave type, upper mould and upper mold core position, together to sinking, form flow-guiding channel obliquely.
Also include connecting the pipette of described die cavity.
Described pipette is provided with sprue bush near one end of die cavity.
The beneficial effects of the utility model:
Bed die is designed as up concave type, aluminium water will be more steady in cavity filling process, reduces aluminium water in flow process
Volume gas phenomenon.Upper mould and upper mold core are made sunk type, mould and the contact area of runner can be made to increase further, to reach
The purpose of foundry goods heat is taken away faster in casting solidification process.
Brief description
Fig. 1 is the utility model overall structure diagram.
Specific embodiment
Embodiment:
Refering to Fig. 1, the utility model is a kind of hub mold structure for Large central aperture, including upper mould 4, is arranged on
Form die cavity after upper mold core 3 in upper mould 4 and spreader 2, and bed die 1, upper mould 4 and bed die 1 matched moulds；Bed die 1 corresponds to foundry goods
Up concave type is made at the position of centre bore, and upper mould 4 and upper mold core 3 position, together to sinking, form flow-guiding channel obliquely.Also wrap
Include the pipette 5 connecting described die cavity.Described pipette is provided with sprue bush 6 near one end of die cavity.
The specifically used method of the utility model, when upper mould, side form, and after the completion of bed die closure, aluminium liquid is passed through to inhale
After liquid pipe and cast gate cover into mold cavity, aluminium water will not be fed directly to product position, but steadily flows up, until filling out
Full bed die groove position just flow to product position.
Beneficial effect: compared with prior art, the beneficial effects of the utility model are: excessively bed die is designed as together recessed
Formula, aluminium water will be more steady in cavity filling process, reduce volume gas phenomenon in flow process for the aluminium water.Upper mould and upper core are made
Sunk type, can make mould and the contact area of runner increase further, be taken away faster with reaching in casting solidification process
The purpose of foundry goods heat.
In the description of this specification, the description of term " embodiment " etc. means with reference to this embodiment or example description
Specific features, structure, material or feature be contained at least one embodiment of the present utility model or example.In this specification
In, identical embodiment or example are not necessarily referring to the schematic representation of above-mentioned term.And, the specific features of description,
Structure, material or feature can combine in any one or more embodiments or example in an appropriate manner.
