Abstract
The present invention is the suction pouring casting mold location structure using diaphragm type cylinder fixed locating stud.It is indoor that suction pouring casting mold is placed in suction casting, want and inhale the stalk aperture alignment of casting room in the down gate channel of casting mold, so that molten iron is inhaled into type chamber from crucible, since sprue is in casting mold bottom, the alignment with stalk hole cannot be observed directly, the existing long positioning pin that sets out of stalk is protruded into from stalk bottom again toward upper end exposing as casting mold positioning use, but verticality of this method due to not can guarantee positioning pin, it will affect the sealing of stalk end flanges, also easily stalk is damaged when installation, now positioning pin is shortened to be positioned by stalk upper port, positioning pin is fixed positioning pin and stalk using diaphragm type cylinder inflation, as long as discharge gas positioning pin takes out under nozzle after being installed, influence of the long positioning pin to positioning is avoided completely, and the damage to stalk.
Description
Technical field
A kind of device of the process for suction casting casting mold positioning of anti-gravity pouring method in foundary industry
Background technique
Suction pouring is a kind of method of anti-gravity pouring, and casting mold is placed in the casting of the suction in vacuum state interior, inhales casting
Crucible suction molten iron fills type to the stalk of room from below, so that molten iron surface and type chamber in crucible is generated pressure using vacuum state
Molten iron sucking is in the type chamber of negative pressure state, fills type non-resistance by difference, and has certain feeding effect.Before inhaling casting, it is necessary to will cast
Type makes lower part down gate in suction casting interior and inhales casting room, and lower part stalk is aligned, then is sealed, and stalk inner hole and type chamber are made
Connection, and sealed with outside, to prevent molten iron from leaking out, but the down gate of casting mold is to be opened in casting mold bottom, is not easy to observe, lean on entirely
It is arranged and inhales casting room bottom surface positioning device in casting mold bottom, to guarantee down gate and the alignment of stalk mouth.
Casting mold is placed to suction casting room and is also easy to produce shaking when with driving handling, can't see positioning device in addition, easily send out
Raw deviations, generate deperssurization emergency.Existing one kind up installs overlength positioning pin in stalk bottom, makes casting mold bottom outlet
Localization method is found accurately with positioning pin, in the middle stalk that occurs on probation by squeeze crack, so that method fails.Mainly 1, positioning pin is necessary
Stalk is up passed through by stalk bottom and to be positioned beyond certain altitude as casting mold in stalk upper end, stalk overall length
For 550mm, positioning pin length will nearly 700mm, and positioning pin bottom is just welded in support base, and is inhaled and cast lower room
Bottom surface is placed on the upper frame of support base.After installation requirement stalk is set in place on positioning pin, stalk upper end
The circumference bottom surface of portion's flange must be with the positioning base Full connected for inhaling the lower room of casting, and the positioning base for inhaling the lower room of casting is mounted in lower room
Bottom surface top is inhaled room bottom surface under casting and is placed on the upper frame of support base, and support base is profile welding structure, and positioning pin is again
It being welded in support base lower frame, positioning pin cannot be guaranteed that vertical relation can be kept with the positioning base for casting lower room is inhaled,
This is one；2, the direction of stalk is really to be oriented to by positioning pin, and stalk internal diameter and positioning pin outer diameter only have 1~2mm
Gap, the verticality in stalk overall length can only be less than 0.06~0.10mm, could work as stalk and put on positioning pin in place, rise
Liquid pipe end flange is pushed down with fixed cover board to be made flange lower flat and inhales the positioning base Full connected for casting lower room to realize sealing.
Since positioning pin and the positioning base for inhaling the lower room of casting cannot keep this vertical range in welding, so stalk
Flange it is inevitable there are gaps with positioning base, when with gland supported flange, since stalk is brittle ceramic material, portion
Point flange periphery will generate a bending moment to flange by pressure, will be to stalk when pressure is more than material damage stress
Cause partial fracture；3, it inhales and casts lower room together with being to leave support base with traveling crane after casting mold installation, driving lifting direction is
Can not the straight line of mechanical guide and positioning pin be consistent, suspension cable shakes in addition, during lifting, stalk can constantly and
Positioning pin squeezes collision and hits, easily damage stalk, increases the damaged condition of stalk.
Summary of the invention
Object of the present invention is to cancel overlength positioning pin to be oriented to stalk, determined by fixing one from stalk top nose end
Position pin, positions casting mold.It after positioning pin is shortened, need only fix at stalk upper flange end, be made using diaphragm type cylinder inflation
Positioning pin is fixed in stalk end hole, is placed and is completed when casting mold, gas in diaphragm is bled off, positioning pin is just by stalk bottom
It is detached from and takes out.
Technical solution: the suction pouring casting mold location structure of diaphragm type cylinder fixed locating stud is utilized.Positioning pin is divided into guiding
Pin and fixed pin two parts, the outside of guide pin is tapered, and is threadedly coupled with rationed marketing.Fixed pin is hollow, in outer diameter cylindrical
It is third on face to be separated by three rectangular apertures, there is internal screw thread at bottom opening, sealing cover is installed, is pressed on the end plane of sealing cover
The end flange side of rubber diaphragm cylinder is pressed on the flange of fixed pin by a tight ring washer, washer, diaphragm type cylinder
Three trisections compress working face, inflate and stretch out in Shi Congtong rationed marketing three openings, pipe fitting, pipe fitting are housed in the middle part of sealing cover
A plastics tracheae is connected, tracheae connects outside the protruded tube of stalk bottom, through quick-release connector with gas source.
Remarkable result of the invention is the influence that stalk is not oriented to by overlength positioning pin in overall length, end flange and
It inhales to cast when lower room is fixed and Full connected may be implemented, flange not will receive bending stress, the diaphragm type cylinder in installing positioning pin
It deflates and retracts, for positioning pin because there is the gap 1~2mm that can be detached from from stalk, stalk does not have any touch in hoisting process
Extruding is hit, guarantees the intact of stalk while casting mold is by positioning.

Fig. 1 is positioning pin fixed structure cross-sectional view.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Wherein, 1, stalk 2, fixed pin 3, guide pin 4, diaphragm type cylinder 5, sealing cover 6, ring washer 7, pipe connect

Specific embodiment
Utilize the suction pouring casting mold location structure of diaphragm type cylinder fixed locating stud.Positioning pin is divided into guide pin 3 and fixes
2 two parts of pin, guide pin 3 is tapered and fixed pin 2 is threadedly coupled, and fixed pin 2 is hollow, the trisection on outer diameter cylindrical surface
It opens there are three rectangular aperture, has internal screw thread at bottom opening.Sealing cover 5 is installed, compresses a ring on the end plane of sealing cover 5
The end flange side of rubber diaphragm cylinder 4 is pressed on the flange of fixed pin 2 by shape washer 6, washer 6, then is pressed with sealing cover 5
Tightly, it when the compression working face K inflation of 4 three trisections of diaphragm type cylinder, is stretched out from 2 three rectangular apertures of same rationed marketing, pushes down liter
The inner hole of liquid pipe 1 realizes positioning, and pipe fitting 7 is housed in the middle part of sealing cover 5, and pipe fitting 7 connects a plastics tracheae 8, and tracheae 8 is from liter
Outside 1 bottom hole protruded tube of liquid pipe, connected by quick-release connector with gas source.
