Also be provided with sealing shroud between location-plate and the hopper successively, ring flange, sealing shroud are installed the back with ring flange and are connected with hopper.
Be provided with top rotary table between mould and last rotating shaft, be provided with lower rotary table between rotating disk and cubic plate, this lower rotary table is connected and fixed by bearing block and cubic plate.
Described top rotary table and lower rotary table are connected and fixed by fixture block.
Described pumped vacuum systems comprises air accumulator, vavuum pump, and the input port of air accumulator connects the blast pipe on the vacuum cavity, and the delivery outlet of air accumulator connects vavuum pump.
On described vacuum cavity, also be provided with a Vacuum door.
Described location-plate is a set square.
Cubic plate in the described vacuum cavity forms cavity with the loam cake of vacuum cavity and lower cover respectively.
Mould rotates under the environment of vacuum in the utility model vacuum centrifugal casting machine, and liquid alloy can be stronger along the flowability of mold cavity, can effectively reduce pore, and shrinkage cavity improves casting density; Alloy-steel casting for thin-walled also can water everywhere, and the quality of foundry goods is greatly enhanced.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As Fig. 1, shown in Figure 2: vacuum cavity is the cavity that two ends are provided with through hole 35, mold turn-table 9 in silica gel mould and the vacuum cavity is installed together, should go up the through hole 35 of the end that rotating shaft 19 passes vacuum cavity after the end face of the charging aperture on the mould is installed with last rotating shaft 19 and be located at rotating shaft 19 and sealing shroud 27 between the orientation triangle plate on 22 axis hole installation.Orientation triangle plate 22 installs and fixes by the cubic plate 23 usefulness screws of column 24 with the vacuum cavity middle part, and vacuum cavity is installed on the casting machine frame.
Between the charging aperture of mould and hopper 6 ring flange 5 and sealing shroud 27 are installed, after ring flange 5 was sealed and matched with sealing shroud 27, ring flange 5 connected hoppers 6, and sealing shroud 27 is connected with the charging aperture of mould by last rotating shaft 19.By hopper 6, ring flange 5, sealing shroud 27, upward rotating shaft 19, orientation triangle plate 22 are connected cooperation with vacuum cavity, form an airtight space, the other end installation mold rotating disk 9 of die feeding mouth, guide rod 18 is connected mold turn-table 9 by cubic plate 23 through holes 33 with dynamical system; On vacuum cavity, be provided with a blast pipe 38, blast pipe 38 is connected with air inlet pipe 32 on the vacuum extractor, vacuum extractor is by vavuum pump 31, pressurization air accumulator 30 and vacuum filtration compression system, electric control system is formed, make the mold cavity in the vacuum cavity form vacuum by vacuum extractor, under the environment of a vacuum, the working of mould.
After casting machine energising work, be located at pumped vacuum systems on the casting machine and at first carry out action vacuumizing in the vacuum cavity, cause and be vacuum state in this vacuum cavity, (also being vacuum state in the mold cavity simultaneously), liquid alloy is through hopper 6, flow through behind the cavity that forms by sealing shroud 27 and ring flange 5, stay into to mold cavity through last rotating shaft 19 again, this moment, dynamical system was rotated through the mold turn-table 9 that guide rod 18 drives on the mould, make liquid alloy flow into each position of mold cavity by centrifugal force, because in the entire die die cavity be vacuum state, so the alloy fluid can not be subjected to flowing of any resistance in die cavity, kirsite can be full of each position (as the mold cavity of thin-walled) of mold cavity, is difficult for producing pore after the kirsite crystallization of fluids, shrinkage cavity, the density of whole foundry goods is higher; Simultaneously for the moulding of thin-section casting also be unlikely to produce the thin-walled place water less than etc. defective.
For the running that makes vacuum centrifugal casting machine more steady, a top rotary table 7 is set between mould and orientation triangle plate 22, top rotary table 7 is connected with orientation triangle plate 22 by last rotating shaft 19, a lower rotary table 8 equally also is set between mold turn-table 9 and cubic plate 23, lower rotary table 8 is connected with cubic plate 23 on the vacuum cavity by bearing block, top rotary table 7 and lower rotary table 9 are connected and fixed by fixture block 3, the die sinking of mould with close China ink in the space that top rotary table 7 and lower rotary table 8 form, when the mould mold closing, guide rod 18 drives mold rotating disk 9, top rotary table 7, lower rotary table 8 rotates together, so design is for mould reduces the vibrations that the casting machine body is produced when rotated, makes body more firm.Thereby obtain more high-quality foundry goods.
For the installation of more convenient mould, on vacuum cavity, be provided with a Vacuum door, mould about being used for.
The description of the foregoing description is just in order to illustrate the utility model more easily, be not in order to limit scope of the present utility model, all by the above principle of specification of the present utility model, simple modification of doing and equivalent variations are the scope of applying for a patent of the present utility model and contain.
