Description
Technical field
The invention belongs to casting technology fields, and in particular to turbine case shell mould ground level stacked box pouring in vertically clamped moulds, which is passed a bridge, is
System.
Background technology
Automobile turbocharger turbine case casting structure is complex, is in single, double runner three-dimension curved surface streamline construction, weight
Several kilograms to tens kilograms, the main wall thickness 4-5mm of volute, and wall thickness became uneven, thermal center lug is more, and casting quality requires height,
It is not allow for any casting flaw.The small-sized volute that current most of producers produce several kilograms uses shell mouding and ground level
Stacked box pouring in vertically clamped moulds mode, simple for process, production cost is low, and casting process yield is up to 70% or more, but due to small-sized volute
Cast quantity it is more, poured weights are few（≤10Kg）, cast height is short, by the way of artificial end can only being used to wrap at present boxes into
Row cast, so, the labor intensity for pouring into a mould worker is big, and the duration of pouring is long, bonded hard ferrite magnet decline it is more, casting be also easy to produce misrun,
Cold shut and decaying spheroidisation, inoculation fade defect.
Invention content
The object of the present invention is to provide a kind of turbine case shell mould ground level stacked box pouring in vertically clamped moulds gap bridge systems, with solution
Certainly the problems mentioned above in the background art.
To achieve the above object, the present invention provides the following technical solutions：Including gap bridge ontology and moving trolley, feature exists
In：The gap bridge ontology includes gap bridge upper body and gap bridge lower body, and the gap bridge upper body and gap bridge lower body are fastened by bolts, described
Gap bridge ontology is placed in moving trolley, and the gap bridge upper body center that includes is provided with sprue and sprue cup, inside fill
Be filled with insulating refractory casting material, cross gate and multiple sprue gates be provided in the gap bridge lower body, inside be filled with it is heat-insulated resistance to
Fiery castable.
Further, several lifting lugs are evenly equipped on the gap bridge upper body and the side of gap bridge lower body.
Further, multiple sprue gates are directed at multiple turbine case shell mould cast gates in the gap bridge lower body.
Further, when pouring one group of shell mould, next group of shell mould is poured into a mould along rail track moving trolley.
Further, the shell of the gap bridge upper body and gap bridge lower body is welded by steel plate, inside be filled with knotting
Castable, the insulating refractory casting material use corundum pouring material, and heat-insulated high temperature resistance is good, and intensity is high, iron-resistant liquid etch
Ability is strong, reusable multiple.
Compared with prior art, the beneficial effects of the invention are as follows：
Present system is simple, and service life is long, and by gap bridge ontology and moving trolley, realization row is hung on casting ladle once-cast
Hundred kilograms of iron liquid amount and multiple shell mould light castings mitigate the drawbacks of avoiding manually pouring into a mould shell mould smallclothes with hand end packet boxes
The labor intensity of worker, improves cast production efficiency, ensure that casting quality.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Refering to fig. 1, Fig. 2, the present invention provide a kind of technical solution：Including gap bridge ontology 1 and moving trolley 5, feature exists
In：The gap bridge ontology 1 includes gap bridge upper body 12 and gap bridge lower body 11, and the gap bridge upper body 12 and gap bridge lower body 11 pass through bolt
3 fastenings, the gap bridge ontology 1 are placed in moving trolley 5, and 12 center of gap bridge upper body that includes is provided with 80 sprues of Φ
12a and sprue cup 2, inside be filled with insulating refractory casting material 12b, be provided in the gap bridge lower body 11 cross gate 11a and
12 40 sprue gate 11b of Φ, inside be filled with insulating refractory casting material 11d.
In the present invention, gap bridge ontology 1 is made of gap bridge upper body 12 and gap bridge lower body 11, and blending bolt 3 is by gap bridge upper body 12
It is fastened with gap bridge lower body 11, prevent iron liquid splashing when cast and lifts case, be also beneficial to iron liquid heat preservation.
In the present invention, 4 lifting lug 11c are respectively provided in the side of gap bridge upper body 12 and gap bridge lower body 11, are easy to lift repairing
