Operation principle of the present invention：When needing centrifuge operation, the installation of mould is first completed, running channel post is fixedly mounted
On die setting base, and ceramic die is connected in running channel column outer wall, while connect upper pouring gate filter in running channel column top,
Into rotary barrel, filling cooling is husky, and cooling sand, which is filled into, floods ceramic die.In order that obtaining stability of rotation, starting at a high speed
Before motor, first slowly run so that cooling sand can be uniformly filled in rotary barrel, then pass through telescopic hydraulic cylinder band
Dynamic stability frame is close to rotary barrel so that guide wheel coordinates with guide wheel rail, completes these preparations, is next exactly conventional electricity
Gas etc. checks, starts high-speed electric expreess locomotive, and now can imports metal liquid into pouring gate filter, and pouring gate filter is by molten metal
In the bits of residual filter off, molten metal now flows downward along running channel post, while under the influence of centrifugal force, molten metal will
Gradually fill up in each ceramic die inner chamber, while start electromagnetic generator, the molten metal in ceramic die is molded, when
After the completion of shaping, gradually to cooling around ceramic die so that after molten metal tentatively solidification, it is possible to by cool down it is husky by
Gradually ceramic die is cooled down, after being cooled to less than 200 degrees Celsius, it is possible to be stripped, complete centrifugal casting.
Beneficial effects of the present invention are:
The present invention uses vertical centrifugal casting, it is possible to increase the size of cast member；Mould is set on the inside of rotary barrel bottom centre
Have mounting seat, thus can more mold exchange according to demand, realize the demand repeatedly produced.
Running channel post side wall is communicated with running channel post multiple ceramic dies in a center of symmetry, can by the rotation of centrifuge
With the multiple cast members of disposal molding.
Running channel column top is connected with pouring gate filter, realizes the last time refined filtration of molten metal, can improve cast member into
Type purity.
It is husky filled with cooling in rotary barrel, in forming process, because ceramic die conduction heat is slower, the molten metal
First smoothly it can enter in ceramic die inner chamber, cooling sand can play a part of insulation at the beginning, to after the completion of being molded below,
Molten metal gradually radiates, and cooling sand takes away heat, while can realize that the heat in cooling sand dissipates to cooling down husky progress heat exchange
Go, so reach the purpose gradually to cool so that the structure in cast member forms more complete.
This programme introduces heat exchanger and cooled down, because heat exchanger can quickly take away heat so that molten metal can coagulate
Knot is quick, and heat exchanger can adjust temperature, and temperature-adjustable causes molten metal to rest on structure formation for a long time
Temperature range.
The stabilising arrangement includes the steady rest being connected to by telescopic hydraulic cylinder on shell, and the steady rest outer wall is set
Have a guide wheel, the rotary barrel outer wall is provided with the guide wheel rail coordinated with guide wheel, due to vertical centrifugal machine rotary barrel height compared with
Height, when rotating, it may appear that vibration, cause rotation unstable, by the stabilization of guide wheel and guide wheel rail, can eliminate and turn
Vibration problem caused by dynamic, to improve the success rate of casting.
Ceramic die upper end is communicated with the earthenware of internal filling pin corrosion material, due to Action of Gravity Field, the top of cast member
Because the inadequate situation of compactness, the present invention introduces the earthenware of filling pin corrosion material on mould for branch, when molten metal flows into
Into ceramic die inner chamber, corrode material meeting heat and disappear, leave the space with negative pressure, now attraction of the molten metal in negative pressure
Under, realize that molten metal flows to the trend of earthenware, thus eliminate the upper part meeting of the cast member caused by outer gravity well
Because the inadequate situation of compactness.
The system is controlled whole rhythm of production in order by PLC, and handles related data by industrial computer,
Whole casting process eliminates the error for thinking operation to be performed fully automatic.
