Description
Technical field
The present invention relates to casting technology field, in particular to a kind of mold of consecutive solidification when realizing gravitational casting.
Background technique
Gravitational casting refers to that molten metal injects the technique of casting mold, also referred to as gravity casting under terrestrial gravitation effect.Broad sense
Gravitational casting includes sand casting, metal mold casting, model casting, lost foam casting, mud mould casting etc.；The gravitational casting of narrow justice
Refer mainly to metal mold casting.
Consecutive solidification principle is that the big position of thickness of shrinkage cavity is likely to occur on aluminium casting by placing the technological measures such as riser,
It solidifies position of the aluminium casting far from riser first, followed by is solidified close to the position of riser, be finally only riser itself and solidify.
As Fig. 8 for example be illustrated, if molding aluminium casting be following shape, in terms of cross-sectional view, on to
Under include successively the first casting unit a, the second casting unit b, third casting unit c, the 4th casting unit d, while the region shared by it is pressed
It according to arranging from big to small, puts in order successively are as follows: the first casting unit a, third casting unit c, the second casting unit b, the 4th casting
Portion d.Irregularly make that its local wall thickness is blocked up, local wall thickness is excessively thin because of aluminium casting shape, is difficult shape so as to cause aluminium casting
At consecutive solidification, thus the defects of shrinkage cavity and shrinkage porosite can be formed inside aluminium casting.
The general wall thickness by adjusting mold at this time, so that the cooling velocity of aluminium casting everywhere is adjusted, it is final logical
The cooperation of mold wall thickness and aluminium casting shape is crossed to realize consecutive solidification, if but aluminium casting part it is increasingly complex, that adjusting
The required factor considered is more when mold wall thickness, relatively complicated when designing mold.
Summary of the invention
The object of the present invention is to provide it is a kind of realize gravitational casting when consecutive solidification mold, can facilitate realization to aluminium casting
Consecutive solidification.
Above-mentioned technical purpose of the invention has the technical scheme that suitable when a kind of realization gravitational casting
The mold of sequence solidification, including left mold and right mould have, and the first left mould of corresponding first casting unit is formed on the left mold
Chamber, the second left die cavity of corresponding second casting unit, the left die cavity of third of corresponding third casting unit, corresponding 4th casting unit the 4th
Left die cavity is formed with the first right mould chamber of corresponding first casting unit, the second right mould of corresponding second casting unit on right mould tool
Chamber, the third right mould chamber for corresponding to third casting unit, the 4th right mould chamber for corresponding to the 4th casting unit, the corresponding second left die cavity
Heating device is provided at left mold, at the right mould tool of the corresponding second right mould chamber to delay the cooling of the second casting unit solidifying
Gu speed corresponds at the left mold of the left die cavity of third, is provided with cooling at the right mould tool of the corresponding third right mould chamber
Device to accelerate the cooled and solidified speed of third casting unit, it is final realize the 4th casting unit, third casting unit, the second casting unit with
And the first casting unit consecutive solidification.
By using above scheme, according in background technique for example, the normal freezing sequence of the aluminium casting is successively
Are as follows: the 4th casting unit, the second casting unit, third casting unit, the first casting unit can not achieve the consecutive solidification of aluminium casting at this time,
Shrinkage cavity is formed inside aluminium casting at this time and the defects of shrinkage porosite, at this time by the left mold of the corresponding left die cavity of third, it is right
It answers and is provided with cooling device at the right mould tool of third right mould chamber to accelerate the cooled and solidified speed of third casting unit, finally realize
4th casting unit, third casting unit, the second casting unit and the first casting unit consecutive solidification.
The further setting of the present invention are as follows: the left mold include four respectively with the described first left die cavity, described second
The corresponding left mould of segmentation of left die cavity, the left die cavity of the third, the 4th left die cavity, the right mould tool include four respectively with
