Description
Technical field
The present invention relates to centrifugal casting apparatus technical field.
Background technology
Centrifugal casting is that metal liquid is in centrifugal force in the mould for rotating the metal liquid injection of molten condition at a high speed
Type is filled in the lower completion of effect.Centrifugal casting is widely used in the casting of cylindrical tube.In existing centrifugal casting mould, it can make
The forming cavity of mould is made of molding sand, so as to conveniently produce various sizes of workpiece.When casting, mold high speed rotation
Turn, then metal liquid is injected to the inside of mould using mozzle, metal liquid forms workpiece under the influence of centrifugal force.So
And because mould is in the rotation of high speed, speed when metal liquid flows out out of mozzle is relatively low, so that metal liquid
There is larger speed difference between mould, so that metal liquid washes away to the molding sand layer of in-mold molding chamber, cause
After used a period of time, the molding sand of forming cavity is just there occurs larger damage for mould, so that mould must be changed,
And then cause the mold use life-span relatively low.
The content of the invention
The invention is intended to provide a kind of centrifugal casting equipment, to solve the service life of centrifugal casting mould in the prior art
The problem of relatively low.
Centrifugal casting equipment in this programme, including supporting mechanism, shaping mechanism and casting mechanism, the supporting mechanism bag
Bottom plate, the first riser and the second riser are included, the first riser is slidably connected with bottom plate in the horizontal direction, and the top of the first riser is provided with
Circular through hole；Between the first riser and the second riser, the shaping mechanism includes for the shaping mechanism and casting mechanism

Connect；The supporting mechanism is provided with the motor that driving first rotating shaft rotates.
Operation principle：Controlled motor drives first rotating shaft to rotate, while by charging aperture toward noting in the storage chamber of gate spool
Enter the metal liquid of melting.First rotating shaft drives mould to rotate by the first end cam and connecting rod.Spring passes through spacing
Plate promotes gate spool to be moved toward the direction away from the first riser, makes gate spool promote the second rotating shaft to be moved toward the direction of first rotating shaft
It is dynamic, and make the second rotating shaft drive the second end cam to be offseted with the first end cam, so that the first end cam passes through the second end cam
The second axis of rotation is driven, and then drives gate spool to rotate.Metal liquid in storage chamber is under the influence of centrifugal force toward storage
The larger end aggregation of chamber, now, because stripper is covered on discharging opening, metal liquid is all stored in storage chamber.With
The increase of the velocity of rotation of first rotating shaft, the axial thrust increase of the second end cam is applied to during first end cam rotation, when
When thrust is more than the elastic force of spring, the first end cam promotes the second end cam to be axially moveable, so that the second end cam
Gate spool is driven to be axially moveable by the second rotating shaft.When gate spool is axially moveable, between gate spool and stripper
Occur it is relative slide so that stripper loses the effect of blocking to discharging opening, make metal liquid in storage chamber from discharging opening
Flow out in forming cavity, metal liquid fills type in forming cavity under the influence of centrifugal force, and then forms workpiece.
Compared with prior art, it is the advantages of this programme：1st, by setting spring, the second rotating shaft and the second end cam,
First rotating shaft is passed sequentially through the first end cam, the second end cam and the second rotating shaft drives gate spool to rotate, so that gate spool
Rotated with together with mould, so as to certain initial velocity, make when metal liquid flow out from discharging opening metal liquid and
Speed difference between the molding sand layer of mould is smaller, so as to reduce souring of the metal liquid to molding sand layer, extends centrifugation
The service life of casting mould.2nd, by setting spring, the first end cam and the second end cam, when the rotation speed of the first end cam
After degree reaches certain numerical value, the first end cam promotes the movement of the second end cam, so that outer sideslip of the stripper from discharging opening
It is dynamic to leave, metal liquid is flowed into out of storage chamber in forming cavity, meanwhile, the mobile of the second end cam can drive gate spool to move
It is dynamic, so that cast tube edge movement side discharging, makes the metal liquid in storage chamber is scattered to be flowed into forming cavity, avoids gold
Excessively concentrated during category liquid outflow and molding sand layer is produced larger the problem of washing away, extend making for centrifugal casting mould
Use the life-span.
Further, the limiting plate is rotatablely connected with gate spool.After limiting plate rotation connection, spring is set to be offseted with limiting plate
When, it can keep relative between spring and limiting plate and stand, so as to reduce the abrasion between spring and limiting plate.
