Template 53 is run up, and so that top template 53 is pushed up guide rod 60 and is moved up centrifugation upper mold 20, during which moves up
Its bottom wall is resisted against making apical axis 52 upward on platform 56 and moving up template 51 for apical axis 52, until playing the top surface of template 51
With centrifugation lower die 10 upper surface flush, at this point, as shown in Fig. 2, top template 53 be resisted against centrifugation lower die 10 lower section, backform
Reach range, mechanism is out of service；The range of the backform is 40 ㎜；
Two, the impurity in casting device is blown off by air gun, sand mold 30 has been placed in template 51, backform device 50 returns
Contracting makes centrifugation upper mold 20 fall and be resisted against 21 inner peripheral surface of type chamber for being centrifuged upper mold 20 on sand mold 30, that is, returns back to Fig. 1 shape
State；
Three, start centrifuge, drive centrifugation lower die 10 to rotate by centrifuge, revolving speed 200-600rpm, molten metal
(as shown by arrows in figure) is injected by the inner hole side end of sand mold 30, molten metal is fast via feeding running channel 32 under the influence of centrifugal force
Type is filled in fast mold cavity 31 outward, type to be filled finishes centrifuge and stops operating；32 position of feeding running channel forms feeding cast gate 71, mold cavity
31 positions form casting 72, and feeding cast gate 71 is connected with 72 bottom end of casting, as shown in Figure 3.When it is implemented, the centrifuge
Rotation time is 20-180 seconds；
Four, backform device 50 stretches out, and repeats the movement of the first step, ejects sand mold 30, and maximum row is arrived on centrifugation upper mold 20 top
Journey；
Five, the formed body for forming sand mold 30, casting 72 and feeding cast gate 71 is released, and replaces sand mold, then carry out next time
Casting.
Six, by feeding cast gate 71 by removing on casting 72, pass through the processing sides such as lathe, water knife, punching machine, electric spark or gas cutting
The removal of feeding cast gate 71 is obtained wanted casting by formula.
By centrifuge speed that the casting device uses for 200-600rpm, the casting that is produced under the centrifugal rotational speed range
Part even tissue can prevent it from gravity segregation occur and happen compared to the rotation of existing high speed centrifugation, casting device gold
It is short to belong to liquid stream diameter, compared to the gravitational casting of existing flow path length, reduces gas and impurity is involved in the several of high-temperature liquid metal
Rate, the defects of reducing airhole.Since the formed body of manufacture has feeding cast gate 71, feeding metal is provided for casting 72
Liquid effectively eliminates the casting flaws such as casting section shrinkage cavity shrinkage porosity, makes the overall structure uniformity of product, after reducing force
The adverse effect that product hermeticity energy and mechanical performance are generated due to Stress non-homogeneity.The casting method can only pass through replacement
Sand mold 30 is just able to achieve batch production, reduces requirement of the continuous casting to centrifugal mold, avoids the high temperature and height of molten metal
Centrifugal force directly to the impact of mold, improves the service life of mold, is suitble to large quantities of automated productions.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
