Abstract
The utility model discloses a vacuum centrifuge which comprises a machine casing, a centrifugal device, a rotating module and a vacuum pumping device, wherein a mounting plate is arranged between the rotating module and the machine casing; the mounting plate and the machine casing are fixed. The vacuum centrifuge is characterized in that the vacuum centrifuge also comprises a hollow ejecting rod; one end of the ejecting rod is connected with a gas cylinder, and the other end penetrates through the mounting plate and is matched with the centrifugal device; one end of the hollow ejecting rod is communicated with a mould cavity, and the other end is connected with the vacuum pumping device. The final charging pressure in the mould is below several hundreds of millibars, only a small amount of air and hot gas comes into contact with the liquid alloy, and then the liquid alloy has strong flowability in the mould cavity, therefore the gas holes and shrinkage holes can be effectively reduced, and the density of the casing is effectively enhanced; the alloy casting with thin wall can be freely cast, and the quality of the casing is greatly improved.
Description
Technical field
The utility model relates to a kind of former, is meant vacuum centrifuge more specifically.
Background technology
At present, the casting machine that is used for centrifugal casting is to inject liquid alloy to mold cavity by charging aperture, rotary die then, the whipping liquid alloy is full of die cavity, treat the alloy liquid crystalline forming after, foundry goods is taken out in die sinking.Liquid alloy has the characteristic that absorbs air, can absorb portion of air when alloy heats up fusion, and along with the rising of liquid alloy temperature, its absorbability is strong more, and the air of its absorption will be discharged with the reduction of the temperature of liquid alloy when temperature reduces.The die cavity of mould is airtight, and gas is also stayed in the foundry goods behind the alloy liquid crystalline forming, forms pore.Hot gas in the mold cavity is discharged by mould self simultaneously, when the hot gas when carrying out new one-step casting in the mold cavity fails all to get rid of, the interior hot gas of mold cavity this moment occupies the space of die cavity, liquid alloy flowing behind mold cavity is not smooth, in the tradition casting, because the metallic solution in the centrifugal effect 50% to 90% of orifices will fully contact with hot gas with the air in the die cavity, air pressure reaches the 3000-4000 millibar at the last type point that fills.Cause the thin-walled place of foundry goods water less than defective.And the vacuum extractor that increases in the periphery of mould at present, the vacuum in the mould is low, and effect is very unobvious, still need have better mode to realize the vacuum state that mould is interior.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of and air total number in the mold cavity is discharged and increases the vacuum centrifuge of the flowability of liquid metals in the mold cavity.
The utility model is implemented by the following technical programs:
A kind of vacuum centrifuge, comprise casing, centrifugal device, rotary die, vacuum extractor, one installing plate is set between rotary die and the casing, this installing plate and casing install and fix, it is characterized in that: also comprise the push rod of a hollow, this push rod one end is connected the other end and passes described installing plate and cooperate installation with centrifugal device with cylinder; One end of hollow push rod communicates with mold cavity, and the other end connects vacuum extractor.
Described centrifugal device is connected with power set, and these power set comprise and be arranged on the casing inner motor, and motor is connected with rotating shaft through belt wheel and drives centrifugal device and rotate.
Between rotary die and last rotating shaft, be provided with top rotary table, between mould and installing plate, be provided with lower rotary table; Top rotary table and lower rotary table are held installation by the fixedly ear clip that is arranged on both sides.
Described vacuum extractor comprises air accumulator, vavuum pump, and the inlet of air accumulator connects push rod, and the delivery outlet of air accumulator connects vavuum pump.
Fill type air pressure below the hundreds of millibar at last in the mould in the utility model, have only few air to contact with liquid alloy with hot gas, make its flowability in mold cavity stronger, can effectively reduce pore, shrinkage cavity effectively improves casting density; Alloy-steel casting for thin-walled also can water everywhere, and the quality of foundry goods is greatly enhanced.
