Technical field
The present invention relates to core shooter fields, and in particular to a kind of core shooter sand hopper that flow velocity can be improved.
Background technique
Penetrating compression molding machine is that molding sand is equably injected to the pre- consolidation of sandbox using compressed air, then apply again pressure into
Row compacting.There are commonly vertical parting flaskless shoot-squeeze moulding machines and horizontal parting slip flask shoot-squeeze moulding machine.Vertical-parting is penetrated without case
Moulding machine modeling is pressed not have to sandbox, molding sand is emitted directly toward the moulding room with template, and made sand mold dimensional accuracy is high, sandbox two sides
There is type chamber, productivity is high, but lower core is difficult, requires molding sand quality stringent.Horizontal parting slip flask shoot-squeeze moulding machine utilizes sand
Case carries out moulding, and mould assembly drawing after sand mold is made, lower core is convenient, and productivity is high.
Core shooter during use, to when covering core sand and spraying, will be needed using sand hopper, however existing sand hopper
Shortcoming is still had during use, firstly, existing sand hopper is often merely able to by the gravity for covering core sand itself
It is moved, movement speed is slower, influences the normal work of core shooter；Secondly, the sand ejection board of existing sand hopper is often single plate
Shape structure can neither cooperate other sand ejection boards to use, and not can increase the stroke for covering core sand, can not prevent from covering core sand
The husky situation of leakage occurs.

Condition occurs, so that high pressure draught can enter the bottom of sand hopper mechanism under the action of the spoiler, can adequately utilize high pressure draught
Flow direction and flow velocity accelerate to core sand is covered.
3, in the present invention, and the high pressure gas of pressure charging valve is when drive is covered core sand and moved, since declined board is with before
Angle in obtuse angle, therefore covers core sand and will collide with declined board between straight panel, in traditional sand hopper, phase between preceding straight panel and declined board
It is mutually vertical, therefore core sand is covered often by direct collision in preceding straight panel, therefore by being obliquely installed by declined board, can be reduced
The collision between core sand and preceding straight panel is covered, reduction covers kinetic energy rejection of the core sand in flow process, further improves and cover core sand
Flow velocity.
4, the present invention in, sand ejection board mechanism during use, connection sand ejection board due to its hole location be universal hole away from, because
This can be assembled with other kinds of core shooter, and since connection sand ejection board has certain thickness, so connection sand ejection board
It can also directly be used separately as sand ejection board.
5, in the present invention, sand ejection board is lengthened while increasing the stroke for penetrating sand, is carried out by way of seamless welding
Assembling, can be during mode penetrates sand, and there is a situation where sand leakages, and the stroke increase for covering core sand may make that covering core sand is spraying
When, spray angle is more accurate.
6, sand ejection board can be realized by the way that silica gel strip and Quick air-discharge slot, Quick air-discharge slot resistant to high temperature is arranged by lengthening sand ejection board
In-house high-temperature gas is quickly discharged, and cooperates silica gel strip resistant to high temperature, so that sand ejection board mechanism is under high temperature environment, also
The service life of device can be improved with prolonged use, reduce the maintenance cost of device.

By using above-mentioned technical proposal so that air-flow can quickly with cover core sand and converged, and it is right to reduce spoiler 5
The blocking area of gas.
One concrete application of the present embodiment are as follows:
In use, core sand is covered by the inside of the injection of feed well 3 sand hopper mechanism 2 in outside, then pressure charging valve 4 passes through outside
High pressure gas is injected the inside of sand hopper mechanism 2 by gas supply mechanism, when covering core sand between two side straight panels 203, high pressure gas
Body will be mixed with core sand is covered, and the kinetic energy for covering core sand is improved by the flowing of air-flow, to realize that the flow velocity of core sand is covered in raising
It is discharged afterwards by bottom, covers the mode that core sand self gravity is flowed compared to traditional dependence, cover core sand shifting after pressurization
Dynamic speed faster, can avoid influencing the case where core shooter works slowly due to covering core sand and being moved through；And inside pressure charging valve 4
Gas can be changed the direction of air-flow by spoiler 5, prevent high pressure draught by air inlet when entering the inside of sand hopper mechanism 2
Slot 3, avoidable high pressure draught will cover the case where core sand ejects outward from air inlet duct 3, so that high pressure draught can be in spoiler 5
Under the action of enter sand hopper mechanism 2 bottom, can adequately be accelerated using the flow direction of high pressure draught and flow velocity to core sand is covered；
And the high pressure gas of pressure charging valve 4 is when drive is covered core sand and moved, due to angle between declined board 205 and preceding straight panel 206
In obtuse angle, it therefore covers core sand and will be collided with declined board 205, in traditional sand hopper, between preceding straight panel 206 and declined board 205 mutually
Vertically, therefore core sand is covered often by direct collision in preceding straight panel 206, therefore by being obliquely installed by declined board 205, it can
The collision covered between core sand and preceding straight panel 206 is reduced, reduction is covered kinetic energy rejection of the core sand in flow process, further improved
Cover the flow velocity of core sand；Sand ejection board mechanism 1 during use, connection sand ejection board 105 due to its hole location be universal hole away from,
It can be assembled with other kinds of core shooter, and since connection sand ejection board 105 has certain thickness, so connection sand ejection board
105 can also directly use separately as sand ejection board；Sand ejection board 103 is lengthened while increasing the stroke for penetrating sand, passes through nothing
The mode of seam welding is assembled, can be during mode penetrates sand, and there is a situation where sand leakages, and the stroke increase for covering core sand can make
Core sand must be covered when spraying, spray angle is more accurate；Sand ejection board 103 is lengthened by the way that 102 He of silica gel strip resistant to high temperature is arranged
Quick air-discharge slot 101, Quick air-discharge slot 101 can realize that the high-temperature gas inside sand ejection board mechanism 1 is quickly discharged, and cooperate resistance to height
The silica gel strip 102 of temperature also can improve the use of device so that sand ejection board mechanism 1 is under high temperature environment with prolonged use
Service life reduces the maintenance cost of device.
