Preparation Method.
Background technology
Model casting is also known as precision-investment casting, and it is a kind of near net-shaped liquid metal moulding process, applies this technique
And each foundry goods obtained is jointly to cooperate comprehensive result through working procedures, multiple material, multiple technologies.Model casting is
Repeat several layers of fireproof coating in dip-coating on the surface of solubility mould, and through successively sanding, be dried and after hardening, with steam and hot water
Etc. heating means, molten for fusible pattern therein going is made overall shell, then carry out high-temperature roasting, cast and obtain the one of foundry goods
Plant casting method.Owing to the size of foundry goods is accurate obtained by this way, corner angle clear, smooth surface, close to zero suspension member
Final form, thus be a kind of Near net shape casting process, therefore be also called hot investment casting.
In model casting, when wax component is injected in mould, there is a defect always.In general, wax component needs
At high temperature become the preferable liquid of mobility, thus be beneficial to its every nook and cranny being filled into required casting object, at pressure
Under effect, this mobility is enhanced.Therefore, it is necessary to wax become completely liquid and be filled into ceramic die each
Time point keeps heated condition.But, when wax is injected in the complex model of zones of different thickness, due to heat stability not
Height, different-thickness region will be with different rate of temperature fall coolings.As suspected, thin region cooling is relatively fast, thick
Region cooling is relatively slow.Therefore, thin region can be to produce to have high-precision specific region.By contrast, thicker region
Wax will cooling time have the trend of contraction to cause dimensional accuracy the highest, since it is desired that manufacture object be an accurate duplication
Wax-pattern.Additionally, because the different cooling in the region of Bao Hehou and contraction, suitable pressure joins in injection wax-pattern, when
During removal mould, model may distort to alleviate pressure.
