Description
Technical field
This utility model is related to hot investment casting field, more particularly to a kind of variable ratio frequency changer shell mould shaking device.
Background technology
In hot investment casting industry, after casting pouring, the arenaceous shell of outer surface is removed by shaking casing equipment.Shake shell
Equipment is with compressed air to shake power.Foundry goods is connected on running gate system tree by group, and shake shell machine is carried out by certain frequency
Shaking force acts on running gate system tree, and under mechanical shock, the arenaceous shell of outer layer can come off running gate system tree, traditional shake shell machine pressure
In 0.7-0.8MPa, flow, the control of contracting air pressure is affected to be constant that the vibration frequency for shaking shell machine is by gas by pipeline section
What the flow of pressure and gas was together decided on, once trachea size is fixed, air pressure constant, the frequency for shaking shell machine is exactly constant.
In actual production, the vibration frequency of some casting moulding system tree very littles can just shake all of shell, and frequency is too high, meeting
Light casting is caused to deform；The big frequency of some casting moulding system trees can just shake all of arenaceous shell, in view of more than
Consider, devise variable ratio frequency changer shaking device.
Utility model content
To solve above-mentioned technical problem, the utility model proposes a kind of variable ratio frequency changer shell mould shaking device, including base, institute
State base and be provided with shell, at the top of the inside the shell, be provided with fixed cylinder, the fixed cylinder outfan is connected with electromagnetic shaker, institute
State electromagnetic shaker bottom and be connected with cast system tree；The electromagnetic shaker is provided with air inlet pipe, and air-flow control is connected with the air inlet pipe
Device processed.
Preferably, the air flow controller include into air parcel, go out air parcel and be located at it is described enter air parcel and it is described go out air parcel
Between shift block；The shift block center is provided with rotating shaft, and the rotating shaft enters air parcel and to go out air parcel through described, under the rotating shaft
Portion is connected with gear level.
Preferably, it is described enter air parcel be provided with air inlet, it is described go out air parcel be provided with gas outlet, arrange in the shift block
There are at least 4 gear holes being sequentially reduced, the air inlet is connected with the gas outlet, the gear hole is in the air inlet and described
Between gas outlet.
The utility model proposes variable ratio frequency changer shell mould shaking device have following beneficial effect：This device is set in original shake shell
On the basis of standby, pipeline is increased, increase a gas flow control device, due to the compressed air pressure of the frequency of electromagnetic shaker and stream
Amount affects, and pressure is fixed, controls uninterrupted, it is possible to control vibration frequency size, according to casting moulding system tree
Feature, devises the device of 4 gear air volume adjustables, rotates shift block, and the gear hole in shift block limits air inflow, so as to adapt to
Vibrations foundry goods shakes the effect of arenaceous shell.
