Description
Technical field
The present invention relates to Casting Technology field, more specifically to a kind of investment casting method.
Background technology
During traditional investment casting method, the shrinkage cavity of casting, rarefaction defect are relatively conventional, particularly light to close
The thick big position of gold such as aluminium, magnesium precision-investment casting medium casting is also easy to produce loose, shrinkage cavity defect, casting qualified rate
Low, blowing is air-cooled easily to make casting produce air-breathing oxidizing fire, secondary casting flaw occurs.Therefore, some cast
Enterprise solves shrinkage cavity, rarefaction defect using cooling-part heat conduction, is usually in shell processed during using cooling-part heat conduction
During just cooling-part is arranged on wax-pattern, the shortcoming of this mode is mainly cooling-part will be with shell
Process need to undergo high-temperature roasting, be easily caused the oxidation of cooling-part outer surface and internal structure change, reduce cooling effect
Really, cast article quality is influenceed.
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 overcomes deficiency of the prior art to provide a kind of investment casting method.
To achieve the above object, the present invention provides following technical scheme：
A kind of investment casting method, comprises the following steps：
1) mould material is configured, the component of mould material and the quality proportioning of each component are 15 parts of paraffin, 15 parts of stearic acid,
25 parts of rosin, 8 parts of ceresine, 30 parts of octadecanoid acid, 7 parts of acetone, by above composition at 45-50 degrees Celsius
Under the conditions of be well mixed；
2) fusible pattern injection, in one layer of turpentine oil of die mould surface smear, by step 1) in the hybrid guided mode material that obtains
Pour into, fusible pattern injection shaping；
3) fusible pattern drying, by step 2) in compressing fusible pattern pass through electrical heating wire heating, drying；
4) shell manufacture, by step 3) in the fusible pattern that obtains combined with running gate system, carry out the manufacture of shell；
5) shell is calcined, to step 4) in the shell that obtains carry out roasting shaping and fix.
Preferably, in step 1) and step 2) between also comprise the following steps：
After expendable pattern material is mixed, it is cooled down through cooling device, be reduced to its temperature and taken the photograph in 30-35
Family name's degree, and it is stirred, mixing time became pasty state at 30-40 minutes.
Preferably, in step 4) and 5) between also comprise the following steps：
In the shell surface uniform application refractory material, make its air-dried placement.
Preferably, the sintering temperature in the step 5 is 900-1100 degrees Celsius, and roasting time is 4 hours.
The present invention is advantageous in that：The method that the present invention is provided so that the production cycle shortens, and improves life
Efficiency is produced, production cost is reduced, casting shell molds good stability has directive significance to actual production.
Specific embodiment
It is made fusible pattern exemplar and is constituted module with expendable pattern material (the usually material of low melting point such as wax material), then
Module surface coatings (refractory material), after solidification to be dried, melts out module heating mould material and forms hollow again
Shell, the casting metal liquid after high temperature sintering, obtains casting after cleaning.Because expendable pattern material is usually cerul
Material, therefore also known as " lost-wax casting ".
A kind of investment casting method, comprises the following steps：
1) mould material is configured, the component of mould material and the quality proportioning of each component are 15 parts of paraffin, 15 parts of stearic acid,
25 parts of rosin, 8 parts of ceresine, 30 parts of octadecanoid acid, 7 parts of acetone, by above composition at 45-50 degrees Celsius
Under the conditions of be well mixed；
2) fusible pattern injection, in one layer of turpentine oil of die mould surface smear, by step 1) in the hybrid guided mode material that obtains
Pour into, fusible pattern injection shaping；
3) fusible pattern drying, by step 2) in compressing fusible pattern pass through electrical heating wire heating, drying；
4) shell manufacture, by step 3) in the fusible pattern that obtains combined with running gate system, carry out the manufacture of shell；
5) shell is calcined, to step 4) in the shell that obtains carry out roasting shaping and fix.
Further, in step 1) and step 2) between also comprise the following steps：
After expendable pattern material is mixed, it is cooled down through cooling device, be reduced to its temperature and taken the photograph in 30-35
Family name's degree, and it is stirred, mixing time became pasty state at 30-40 minutes.
