Description
Technical field
The present invention relates to precision casting production equipment technologies, and in particular to a kind of fusible pattern for precision casting production
Molding machine.
Background technique
Precision casting refers to obtaining the general name of accurate-size casting process.It is accurate relative to traditional sand casting process
The casting dimension that casting obtains is more accurate, and surface smoothness is more preferable, and model casting typically refers to that apperance is made in fusible material,
Shell is made in apperance surface cladding several layers refractory material, then apperance is melted discharge shell, to obtain the casting without die joint
Type, after high-temperature roasting can back-up sand casting founding method.It manufactures since wax material is widely used in apperance, therefore will often melt
Die cast is known as " lost-wax casting ".
The production process of precision casting is；
1, suitable expendable pattern material (such as paraffin) is selected to manufacture fusible pattern；
2, it repeats to be stained with fireproof coating on fusible pattern and spreads fire sand process, harden shell and drying；
3, internal fusible pattern is melted away again, acquisition type chamber；Roasting shell is to obtain enough intensity, and burns up remnants'
Expendable pattern material；
4, metal material required for being poured；
5, solidification cooling, sand removal after shelling, to obtain high-precision finished product.
Once integrally at casting, material consumption is not only reduced, but also simplify technique with precision-investment casting now, save work
