The technological parameter of mark, each module is processed on Digit Control Machine Tool by the high-quality copolymerization cystosepiment using any surface finish inner core ripening
Molding；
S2: several concatenation module assembly of machine-shaping are bonded to an entirety, then by paint specially for disappearing cast mold
Be placed in mould wash mixer the stirring that adds water, with leaching, brush, spray, drench method to complete bond after model surface coating, then will
The good model of dip-coating is 40-50 DEG C in temperature, and relative humidity is to be dried process in the drying room of 30-35%；
S3: the sandbox with aspirating chamber is put simultaneously clamping on a vibration table, then puts into dried model in sandbox, and plus
Sand is pre-buried, then imposes vibration 50-100s, then places cup with plastic sheeting sealing sandbox, finally with vacuum pump by sandbox
It is evacuated；
S4: the aluminum solutions that melting is handled well pour in model, after aluminum solutions pour completely to cup, in negative pressure 0.015-
Discharge vacuum under 0.025mpa state, under normal temperature state, then cool down 2-3h, then unpack and take out the mould casting of cooling shaping
Part, can get the strand of inner container of icebox mould after cleaning.
Preferably, in described s2, with leaching, brush, spray, drench method to complete bond after model surface coating, then will
The good model of dip-coating is 42-48 DEG C in temperature, and relative humidity is to be dried process in the drying room of 31-34%.
Preferably, in described s3, finally with vacuum pump, sandbox being evacuated is for intrinsic pressure with model by atmospheric pressure
Sand grains is bonded together by the difference of power.
Preferably, in described s4, discharge vacuum under negative pressure 0.018-0.023mpa state, then cold under normal temperature state
But 2.2-2.8h, then unpacks and takes out the mould cast of cooling shaping, can get the strand of inner container of icebox mould after cleaning.
In the present invention, a kind of described lost foam casting process manufactures the method for inner container of icebox mould strand by using three
Dimension software carries out three-dimensional modeling and design, then carries out module cutting, and mark related process parameters making mould strand size
Precisely stable, by each module machine-shaping can be greatly shortened on Digit Control Machine Tool by modelling week using copolymerization cystosepiment
Phase, it is to avoid waste raw material, fabrication cycle of the present invention is short, size is precisely stable, it is to avoid the waste of raw material and environment is made
The pollution becoming, and operating technology difficulty is little, method is simple, easy to use, low cost.
Specific embodiment
With reference to specific embodiment, the present invention is explained further.
Embodiment
The present embodiment proposes a kind of method that lost foam casting process manufactures inner container of icebox mould strand, including following
Step:
S1: using three-dimensional software, by drawing technical requirements, three-dimensional modeling and design are carried out to inner container of icebox mould, then by three-dimensional
Model is cut as several concatenation module by mould own characteristic and casting demand, and marks related process parameters, then foundation
The technological parameter of mark, each module is processed on Digit Control Machine Tool by the high-quality copolymerization cystosepiment using any surface finish inner core ripening
