Description
Technical field
This utility model is related to centrifugal separating machine stainless steel pricker section rotary drum production and processing technical field and in particular to one kind
Vertical centrifugal casting mould.
Background technology
At present, the production method of centrifugal separating machine stainless steel pricker section rotary drum mainly have following several:
First method is static casting.First, the external form according to stainless steel pricker section rotary drum and size determine more than processing
Amount, determines stainless steel pricker section drum blank shape and size.Secondly, according to the stainless steel pricker section drum blank shape determining and chi
Very little produce moulding cone section rotary drum wooden model apperance, using cone section rotary drum external mold and core box wooden model apperance carry out phenolic sand molding,
After the completion of moulding, high-temperature molten steel qualified for melting is poured in resin bonded sand mould and produces stainless steel pricker section drum blank.Finally,
Carry out being machined into finished product according to stainless steel pricker section rotary drum drawing dimensional requirement, finished product stainless steel pricker section rotary drum is carried out lossless
Detection, determines if there is injurous defect.
Its shortcoming is the stainless steel pricker section drum blank that static casting produces, and easily producing pore, burning into sand, crackle etc. has
Evil casting flaw, for surface pores or shallow burning into sand etc., generally can process to eliminate by subsequent mechanical, but in great majority
In the case of be still difficult to eliminate it is impossible to ensure product quality after machining, or even scrap.Meanwhile, the stainless steel pricker of static casting
Section rotary drum needs reserved larger allowance, so that product yield is substantially reduced, leads to cost to steeply rise.In addition,
The stainless steel pricker section drum blank being produced using the method, the production cycle is longer, and wooden model is fragile, produces into during production in enormous quantities
This is higher, leads to integrated cost to rise.
Second method is forging method, mainly the profile according to centrifugal separating machine stainless steel pricker section rotary drum and size,
Determine profile and the size of stainless steel pricker section drum blank forging, then by the way of forging, produce stainless steel pricker section rotary drum
Blank, carries out machining molding finally according to centrifugal separating machine stainless steel pricker section rotary drum finished form and size.
Its shortcoming primarily with respect to the less stainless steel pricker section rotary drum of diameter it is impossible to directly forge blanking inner hole so that
Endoporus mechanical processing difficulty increases, and forging process surplus is relatively large, and product yield is relatively low.Meanwhile, centrifugal separating machine is not
Rust steel pricker section rotary drum, the technique productions stainless steel pricker section drum blank using forging is relatively costly, the cone particularly to major diameter
Section rotary drum, diameter is bigger, and its forging blank cost is higher.
Utility model content
This utility model overcomes the deficiencies in the prior art, provides solution a kind of vertical centrifugal casting mould.
For achieving the above object, this utility model employs the following technical solutions:
A kind of vertical centrifugal casting mould, it includes metal adventitia, and described metal adventitia upper end is connected with baffle plate, lower end even
It is connected to base plate, in described metal adventitia, intracavity is provided with core, described core upper end is provided with refractory brick, lower end and base plate even
Connect, in the middle part of described core, be provided with arbor, described arbor lower end is connected with base plate.
Further technical scheme is, described arbor is seamless steel pipe, and described seamless steel pipe offers several holes.
Further technical scheme is, described base plate is provided with lower refractory brick in itself and metal adventitia junction.
Further technical scheme is, the shape of the shape and size of described metal adventitia inner chamber and stainless steel pricker section rotary drum
Shape and size match.
Further technical scheme is, the shape of the shape and size of described core and stainless steel pricker section rotary drum endoporus and
Size matches.
Further technical scheme is, described metal adventitia upper end is connected with baffle plate by pin, described metal adventitia
Lower end has been connected by screw base plate.
In the technical program by by the shape and size of metal adventitia inner chamber be set to stainless steel pricker section rotary drum outside
The shape and size of profile match, and so can control profile and the chi of stainless steel pricker section drum blank by metal adventitia
Very little, by the shape and size of core exterior contour being set to the shape and size phase with stainless steel pricker section rotary drum endoporus
Join, so can control hole size and the shape of stainless steel pricker section drum blank by core, by metal adventitia and core
Combination, farthest control the allowance of stainless steel pricker section rotary drum Internal and external cycle, by core upper end setting on resistance to
Firebrick, so can buffer the high temperature metal liquid pouring in metal adventitia inner chamber, adopt seamless steel pipe by arbor, seamless
Multiple apertures are drilled with steel pipe, the gas in core can be discharged from base plate by aperture, make high temperature metal liquid pour into gold
After belonging to adventitia inner chamber, the gas that core produces will not be swollen for core bad, under being provided between base plate and metal adventitia
Gap between metal adventitia and base plate is eliminated by lower refractory brick, can prevent high temperature metal liquid from gap by refractory brick
Interior outflow, meanwhile, high temperature metal liquid is separated by lower refractory brick with base plate, prevents excessive heat transmission to base plate.
Compared with prior art, the beneficial effects of the utility model are:
The blank of centrifugal separating machine stainless steel pricker section rotary drum is produced after being combined with sand mold using metal outer mold, metal
The chilling action of external mold, is conducive to directional solidification, the cavity shape of metal outer mold and the size root of stainless steel pricker section drum blank
Profile and size according to stainless steel pricker section rotary drum determine, so that the allowance of stainless steel pricker section rotary drum outer surface is controlled.Sand
Type is primarily used to form the endoporus of stainless steel pricker section rotary drum, and its shape and size is walked around according to stainless steel pricker section the shape of bulging endoporus
And size determines, the allowance of stainless steel pricker section rotary drum endoporus is made to be effectively controlled.Metal outer mold combine with sand mold with
Afterwards, both make the product yield of stainless steel pricker section rotary drum greatly improve, and production cost substantially reduces.Gas in die cavity,
After molten metal pours into, the agitation of generation, be conducive to the floating of impurity in molten metal, the stainless steel pricker section drum blank produced,
Harmful casting flaw such as pore-free, burning into sand, crackle, the stainless steel pricker section rotary drum finished product being machined into, through performance detection with no
The technical requirements of product and standard are all reached after damaging detection.Meanwhile, the combination of the two, makes production larger diameter stainless steel pricker section turn
The overall center of gravity of drum mold system declines, and improves safety during cast.Bottom refractory brick, can effectively stop molten metal heat
Substantial amounts of be transferred on base plate, be finally transferred to vertical centrifugal machine, vertical centrifuge has preferable protective effect.
