Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
First embodiment:
As shown in Fig. 2 to Fig. 6, in the present embodiment, Pneumatic vibrator 2 includes: valve body 3, valve deck 7 and movable part 6.
Valve body 3 and valve deck 7 form valve component, wherein the slideway that there is valve body 3 left and right to extend, valve deck 7 are detachably arranged in valve body
On the 3 and left side port of sealing chute；Slideway has the first chute sections 14, the second chute sections positioned at right side positioned at left side
15, the third chute sections 16 between the first chute sections 14 and the second chute sections 15；It is offered on valve body 3 and directs the air into
The inlet channel 8 of three chute sections 16 and by air outlet passageway 9 derived from the second chute sections 15.Movable part 6, with can phase
Slideway is slidably connected to the mode that slideway or so reciprocatingly slides；The movable part 6 includes: the internal perisporium of periphery wall and the first chute sections 14
Seal the first movable part of cooperation, periphery wall and the second chute sections 15 internal perisporium with second movable part in preset gap,
Periphery wall is closely attached on the third movable part of the internal perisporium of third chute sections 16；Between between second chute sections 15 and the second movable part
Gap forms the second air cavity 11；The internal perisporium of the left side of first movable part and the first chute sections 14, the right side of valve deck 7 surround the
One air cavity 10；Third movable part is to connect to vibrating member.Movable part 6 is configured with an air guide channel 13, the air guide channel 13
Single port is opened in the left side of the first movable part to be connected to the first air cavity 10, and the another port of air guide channel 13 is opened in second
The periphery wall of movable part is to be connected to the second air cavity 11；And the another port of air guide channel 13 is past with respect to slideway or so in movable part 6
It is corresponding to switch between the second air cavity 11 of connection and the state for the air inlet for being connected to outlet passageway 9 when sliding again.In the present embodiment
In, it is S1, the second air cavity 11 and activity that the first air cavity 10 and movable part 6, which are in contact and are projected on the effective area of slideway axial direction,
The effective area that 6 phase of part is projected on slideway axial direction is S2, S1 > S2.
As shown in Figure 4, in the present embodiment, Pneumatic vibrator 2 have inlet suction port 4, the inlet suction port 4 configuration into
On gas channel 8, inlet suction port 4 is to connect extraneous gas source, and in the present embodiment, inlet suction port 4 connects an air pump, described in air pump
The air of confession is by inlet channel 8 and air guide channel 13, into the second air cavity 11 and the first air cavity 10, wherein provides described in air pump
Gas pressure intensity be P, the gas pressure intensity of the first air cavity 10 and the second air cavity 11 is P1 and P2.State as shown in Figure 4, P=P1
=P2, air in the first air cavity 10 generate a power F1=P1S1=PS1 to the right to movable part 6, in the second air cavity 11
Air generates a power F2=P2S2=PS2 to the left to movable part 6, and due to S1 > S2, F1 > F2, movable part 6 can to the right
Activity.
As shown in Fig. 5 and Fig. 6, in the present embodiment, when the activity to the right of movable part 6 to inlet channel 8 and outlet passageway 9 it
Between when, the one end of air guide channel 13 far from the first air cavity 10 is close to the second slideway, when movable part 6 continues movable to the right, the first gas
Pressure in chamber 10 will become smaller, at this time P1 < P2=P, F1=P1S1, F2=P2S2=PS2, can be after in order to meet movable part 6
Continuous movable to the right, the difference between S1 and S2 needs sufficiently large.Specifically as shown in Figure 5 and Figure 6, according to universal gas law PV
=n*R*T (amount that P is pressure, V is gas volume, n expression gaseous matter, and T then indicates the thermodynamic temperature of perfect gas；
There are one constants: R is ideal gas constant.) ignoring the variation of temperature, n*R*T is constant in advancement for movable part 6,
Therefore it obtains:
(P1- Δ P) (V1+ Δ V)=P1V1；
(P1-ΔP)*S1>P1*S2；
And V=S*L；(wherein, the variable quantity that Δ V indicates 10 volume of the first air cavity)
It is calculated: L2-L1=Δ L < (S1-S1) L1/S1, (wherein, the distance that Δ L indicates the advance of movable part 6).That is:
When the distance between inlet channel 8 and outlet passageway 9 are less than (S1-S1) L1/S1, movable part 6 movable can arrive air guide channel
13 the first air cavitys 10 of connection and outlet passageway 9, as shown in fig. 6, the air in the first air cavity 10 will be from 9 row of outlet passageway at this time
Out, until the pressure in the first air cavity 10 is equal to atmospheric pressure.Since the pressure in the second air cavity 11 at this time is still air pump
The pressure P supplied, is much larger than atmospheric pressure, therefore F1 < F2, movable part 6 will activity to the left until the state of Fig. 5 is arrived in activity, with
Standby cycle events next time.In the present embodiment, it can be only fitted to work to implement to hit the connector (not shown) of vibration
On moving part 6, the movement for hitting vibration is realized with the left and right activity of movable part 6.
As shown in figure 4, in the present embodiment, Pneumatic vibrator 2 has sealing element 12, which is nested with first
On movable part, sealing element 12 is to seal the cooperation between the first movable part and the first chute sections 14.In the present embodiment, pneumatically
There are two sealing element 12, which is nested on the first movable part the tool of formula vibrator 2 respectively, can play preferably
Sealing function.In the present embodiment, sealing element 12 is O-ring seal.
As shown in Fig. 5 and Fig. 6, in the present embodiment, the radial dimension of the first movable part is greater than the interior of the second chute sections 15
Portion's radial dimension, the second chute sections 15 can limit movable part 6 and be detached from from the slideway of valve body 3.As shown in Fig. 2 and Fig. 4, bobbing machine
Structure also has muffler 5, which configures on outlet passageway 9, and valve deck 7 is removably configured by bolt in valve body 3
On.
As shown in Figure 6, a kind of core shooter 1 has to inject molding sand to core box to prepare sand core to inject to core box
The sand shooting mechanism of molding sand, and the vibrator to vibrate sand shooting mechanism, the vibrator are a kind of above-mentioned Pneumatic vibrator
2.The Pneumatic vibrator 2 can be realized 1 structure of vibration core shooter of appropriate intermediate frequency, make the cause of the molding sand in 1 structure of core shooter
Close degree is appropriate, improves the sand core quality of preparation.Since the vibrator is driven by gas, it is not required to by motor etc.
Driving equipment, structure is simple and energy consumption is few, it is possible to reduce cost.
Second embodiment:
As shown in Figure 7, in the present embodiment, the guide section that the right side of valve body 3 extends to the right there are also one section, which can
To play the role of guiding, the convenient activity to implement to hit the connector of vibration.In addition, in this embodiment, valve deck 7 is set
It is equipped with the protrusion to limit the movable maximum distance to the left of movable part 6.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
