Description
Technical field
The present invention relates to precision casting technology field, more specifically to a kind of investment precision casting technology.
Background technology
The product that precision-investment casting is obtained is accurate, complicated, close to part final form, can not process or very
Few processing is just directly used, and is a kind of advanced technologies of near-net-shape, is an excellent technique in casting industry
Technology, its application is widely.It is not only used for the casting of the various alloys of all kinds, and produce
Casting dimension is accurate, surface quality is higher than other casting methods, or even other casting methods answering of being difficult to cast
Miscellaneous, high temperature resistant, the casting for being not easy to processing, can be cast using model casting.
With model casting precision castings towards the development of integration, thin-walled property and maximization, the compacting of wax-pattern and pressure
The design of type encounters new challenge, and the flowing of moltening mold castings mould material is presented non-Newton fluid characteristic, different groups
Into mould material there are different rheological behaviors；Same mould material can also show different under different external force effects
Mobile performance.Mould material and its suffered external force determine that wax-pattern fills the actual filling mould states of die mould, then also determine
The precision of cast casting.
It is those skilled in that art urgently to be resolved hurrily therefore, because there is above-mentioned technological deficiency in the prior art
Technical problem.
The content of the invention
The purpose of the present invention solves the deficiencies in the prior art to provide a kind of investment precision casting technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of investment precision casting technology, comprises the following steps：
(1) mould material is configured, the component of mould material and the percentage of each component are paraffin 30%, stearic acid 30%, pine
Fragrant 20%-30%, ceresine 10%-20%, above each component is mixed under 50 to 60 degrees Celsius of temperature conditionss
Into uniform one, then in the case of cooling, mould material is stirred vigorously, mixing time is 30 minutes, is made
Mould material is used as paste state voltage supply fusible pattern；
(2) fusible pattern injection, one layer of turpentine oil is coated on die mould surface, and paste shape mould material is poured into, and compacting is molten
Mould；
(3) will shape fusible pattern drying, repaired a die afterwards, organize it is viscous, inspection, then by product model with
Running gate system is combined, and obtains module；
(4) refractory material is coated in the outer surface of module, carries out the manufacture of shell；
(5) shell that will have been manufactured is calcined, 900 degrees Celsius of sintering temperature, roasting time 3-4 hours,
Melt the wax-pattern in shell and remove and formed stabilization shell；
(6) to cast product material aluminium alloy in the shell after roasting；
(7) clear up shell when product material aluminium alloy is cooled to 600 degrees Celsius, after solidification and obtain casting.
Preferably, in step (1) component of mould material and each component percentage for paraffin 30%, stearic acid 30%,
Rosin 20%, ceresine 20%.
Preferably, in step (1) component of mould material and each component percentage for paraffin 30%, stearic acid 30%,
Rosin 25%, ceresine 15%.
The present invention is advantageous in that：Wax-pattern is unlikely to deform, casting dimension good stability；Labour intensity is low,
Production efficiency is high；Raw material are using abundant, low production cost；Casting has dimensional accuracy very high and surface light
Cleanliness.
