Background technique
Ingot mould casting is a kind of relatively simple casting method, has the advantages that easy to operate, small investment, at low cost, water
Cold mold has hollow die wall, is cooled down by recirculated water, can control cooling speed by adjusting hydraulic pressure or control water temperature
Degree, relative to swage cooling effect more preferably and convenient for control cooling velocity, in the centre that ingot casting is final solidified, due to shrinking
The collection Hole of appearance is known as central pipe, dispersion and tiny hole is known as shrinkage porosite, this is mainly due to areas each when pouring
The curing condition difference in domain and caused by, central pipe is that column crystal is excessively flourishing and generates since slab is in process of setting
" bridging " phenomenon, the volume contraction that occurs when the liquid phase of " bridge " below is solid phase, cannot be supplemented by molten aluminum caused by,
By liquid phase be solid phase during, molecular order can by disorder to order, from the distant to the near, macro manifestations be substance density
Difference, the volume for occupying stoste mutually are reduced, and the ingot casting edge close to ingot mould can preferentially be solidified well due to cooling condition, more
Slower close to centre thermal diffusion, solidification also can be slower, i.e., top starts edge solid phase area occur when solidification, and intermediate region is solid
The phenomenon that liquid two-phase section, center is liquid phase region, the volume contraction of different zones becomes larger from outside to inside after solidification completely, from
And it will form the central pipe of " V " shape.
It is subsequent to be difficult to carry out the plastic processing such as squeezing since " V " shape central pipe exists, it is necessary to be cut using machining
It removes, the process for not only having increased one of machining in this way, but also wastes raw material, reduce lumber recovery, in view of the above-mentioned problems, spy mentions
A kind of deformation aluminium and aluminium alloy ingots die cast are solved the above problems with water cooling mould out.

It is as above-mentioned technical proposal to further describe:
It is welded with baffler between the internal model outer wall and die ontology, is located inside die ontology above the baffler and is formed
Die wall cavity, the baffler lower section, which is located inside die ontology, forms circulation pipe cavity.
It is as above-mentioned technical proposal to further describe:
The die ontology and internal model are cylindrical structure.
It is as above-mentioned technical proposal to further describe:
The circulation pipe material is copper, and distance is not more than 2mm between circulation pipe.
It is as above-mentioned technical proposal to further describe:
The air inlet offers multiple, and air inlet is uniformly opened in one side surface of die ontology.
It is as above-mentioned technical proposal to further describe:
The exhaust outlet offers multiple, and exhaust outlet is uniformly opened in another side surface of die ontology.
It is as above-mentioned technical proposal to further describe:
The small-sized fan is provided with multiple, and small-sized fan spacing distance is incremented by from the bottom to top, and small-sized fan and blower
Plug wire mouth is electrically connected.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, in the present invention, circulation pipe is used, circulation pipe is surrounded on inner mould surface and is located at circulation pipe cavity inside, and cold water is from water inlet
Mouthful enter circulation pipe, is up raised slowly to water outlet discharge in along spiral shape, the molten aluminum held to internal model inside is from below to up
Cooling, the final solidified region of ingot casting at top can eliminate the difference of ingot casting edge and centre cooling condition, will not go out
The phenomenon that existing border region preferentially solidifies, in this way in the transition process in molten aluminum from liquid phase to solid phase, only will appear whole and equal
Even volume contraction, small without edge volume contraction, central volume shrinks big phenomenon, so as to avoid there is center
Shrinkage cavity reduces material loss end to end, improves yield rate, while being also convenient for subsequent carry out plastic processing.
2, in the present invention, small-sized fan, air inlet and exhaust outlet are used, molten aluminum is after entering internal model, circulation pipe cavity
Internal temperature increases, and increases circulation pipe temperature by heat transfer, and cold water is after entering circulation pipe, circulation pipe hull-skin temperature drop
It is low, water condensation is had in hot-air in circulation pipe surface, and small-sized fan drives air to be delivered to exhaust outlet from air inlet, is formed
The water evaporation heat absorption that wind accelerates circulation pipe surface is flowed, the effect of water cooling is improved, further avoids that central pipe occur existing
As.
