Impeller is cased with outside one end in main exhaust tube, branch exhaust tube and main exhaust tube side wall are rotatablely connected.
It is in place of the deficiencies in the prior art, when above-mentioned sandbox in cabinet to vacuumizing, main exhaust tube is located at cabinet outer one
End is connected to asepwirator pump, is aspirated by asepwirator pump, the gas in molding sand in sandbox is by suction, intensively to branch exhaust tube
Nozzle flowing, gas flow through suction hole, branch exhaust tube and main exhaust tube discharge sandbox outside；Molding sand around bronchus mouth is tight
When solidity is preferable, for the molding sand far from branch pumping nozzle there is still a need for continuing to vacuumize, be required with reaching casting, the pumping of above-mentioned sandbox is true
It is empty inefficient.
Utility model content
The purpose of the utility model is to provide a kind of dispellable mould casting sandboxes, and which solve vacuumizing for existing sandbox
Inefficient problem has the advantages that improving sandbox vacuumizes efficiency.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of dispellable mould casting sandbox, including sandbox ontology, several exhaust tubes for being set to the sandbox body outer wall,
It is multiple to be fixed on the external grizzly bar of sandbox sheet, coaming plate and negative pressure channel are provided in the sandbox ontology, in the sandbox ontology
It is provided with coaming plate, the sandbox ontology is divided into casting cavity and between the coaming plate and the sandbox ontology by the coaming plate
Interlayer；It is uniformly distributed the through-hole for being provided through multiple connection casting cavities on the coaming plate, is provided in the interlayer more
A metal hose with gap, the through-hole are connected to the metal hose.
Using the above scheme, in actual use, it is filled with molding sand in casting cavity, needs to take out molding sand before casting
Vacuum, i.e. gas in molding sand successively pass through through-hole, interlayer and exhaust tube and are pulled out sandbox ontology；Simultaneously by interlayer and sets of vias
The aspirating chamber of molding sand surrounding is distributed at one, and through-hole is evenly distributed on coaming plate, molding sand surrounding can equably be taken out
Vacuum, that improves sandbox vacuumizes efficiency；In sandbox vacuum, part molding sand is drawn into interlayer with air, part
Molding sand is sucked into metal hose with air-flow, and gas is extracted sandbox ontology by the gap on metal hose, and little particle
Molding sand is blocked in metal hose, using the above structure, is avoided molding sand from blocking exhaust tube, is further increased vacuumizing for sandbox

Dynamic to generate a series of chain reaction, i.e. sealing plate one drives the sealing connecting with sealing plate one along the sliding of guide surface
Plate two is slided along coaming plate, is driven other associated sealing plate slidings with this, is finally realized the Relative sliding of all sealing plates, i.e.,
The intrinsic negative pressure condition of sandbox can be adjusted, while quickly convenient for the maintenance in interlayer.
Further preferably are as follows: the quadrangle of the outer wall of the sandbox ontology is provided with L-type lock, and the L-type lock is fixed on
On the grizzly bar, it is provided with mounting hole between the L-type lock and the sandbox ontology, is embedded with bending in the mounting hole
Baffle, the baffle is for limiting moving horizontally for the sealing plate.
Using the above scheme, on the basis of the chain reaction that the guide surface based on end plate end generates, only work as quadrangle
Baffle be removed after, sealing plate could be removed from sandbox ontology and coaming plate, with this avoid extraneous factor interference make it is close
Sealing plate slides with respect to sandbox easily, guarantees the vacuum degree in the casting cavity in sandbox casting process with this.
Further preferably are as follows: the baffle upper end is fixed with pressing plate, and the lower end surface of the pressing plate contacts at the sealing plate
On.
Using the above scheme, by compressing sealing plate using pressing plate, sealing plate and sandbox ontology and coaming plate are further ensured that
Between bonding strength, the sealing effect being further ensured that in interlayer guarantees with this in casting cavity in sandbox casting process
Vacuum degree.
Further preferably are as follows: the through-hole is interconnected tapered hole and flaring hole, and the tapered hole is located at close to institute
Casting cavity side is stated, the flaring hole is located at close to the interlayer side.
Using the above scheme, by through-hole be set as it is tapered gradually include it is hourglass-shaped, when gas in sand mold reaches tapered hole, by
It being gradually become smaller in through-hole diameter, gas flow rate is accelerated, when gas passes through flaring hole again, since through-hole diameter becomes larger, gas
Flow range is gradually expanded, and when gas is flowed out from through-hole, flow velocity and diffusion zone are larger；By the setting of guide surface,
Flow velocity transition is more stable when flowing a gas over each section, prevents gas from mutually colliding, and negative pressure channel is made to be able to maintain higher take out very
Air speed degree.
In conclusion the utility model has the following beneficial effects:
