Description
Technical field
The invention belongs to machine casting fields, and in particular to the plane vertical pouring shell structure of thick big high-Ni-Cr cast iron volute.
Background technology
Automobile turbocharger volute casting structure is complex, is in single, double runner three-dimension curved surface streamline construction, especially
The big high-Ni-Cr cast iron volute of thickness that heavy-duty car uses, weight reach seventy or eighty kilograms, the main wall thickness 8-10mm of volute, and wall thickness thickness
Unevenness, thickest 50mm, thermal center lug is more, and casting quality requirement is very high, needs PT, RT, UT to detect, is not allow for any casting
Make defect.Since nickel content is high in high-Ni-Cr cast iron, pouring temperature is high, and the body shrinkage of molten metal is big, and casting is also easy to produce shrinkage cavity, contracting
Loose defect.
Conventionally produced thick big high-Ni-Cr cast iron volute casting pours resin sand production technology, in order to ensure using putting down to do to put down
The internal quality of casting needs the 2-3 insulated feeder of placement at the big thermal center of thickness of casting that could meet Customer Quality class requirement.
And the flat setting for pouring running gate system is bound to grow, and consumes more molten metals, the product yield of casting only has 40%, also increases
Operating time of worker, substantially increase casting cost.
Invention content
The plane vertical pouring shell of thick big high-Ni-Cr cast iron volute is provided the invention aims to overcome the deficiencies in the prior art
Type structure.
In order to achieve the above objectives, the technical solution adopted in the present invention is：The plane vertical pouring shell of thick big high-Ni-Cr cast iron volute
It is used as whole shell mould after type structure, including left housing type and right shell mould, left housing type and the fastening of right shell mould mould assembly, is arranged in the whole shell mould
It includes sprue and ingate, the top of the whole shell mould to have volute cavity, sand core, chill and running gate system, the running gate system
Face is provided with sprue cup and exhaust piece, overpays whole shell mould and is embedded in successively in the sandbox equipped with shot.
Optimally, in the whole shell mould running gate system use sprue and riser one laterally pushed type running gate system.
Further, the sprue cup is high temperature resistant alumina-silica ceramic pouring cup, and the lower end in sprue cup is provided with bubble
Foam ceramic filter.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is using the shell structure mode of plane vertical pouring, shell mould back of the body ball, and running gate system is using sprue and riser one
Laterally pushed type running gate system and sprue cup with filter, feeding efficiency is high, and feeding pressure is big, and casting process yield reaches
70% or more, production cost is greatly reduced, the internal quality of casting and surface quality are improved.
