The sand removal process of the sand removal equipment of the utility model mainly has following process：
Shake sand removal：It is molding to needing by print head since in 3D printing, all spaces are all paved with sand grains
Area spray bonding agent carries out hardened forming.Bonding agent needs just harden by catalyst.General catalyst premixing is in sand
In grain, i.e., the loose sand for not spraying bonding agent is the sand grains for being mixed with catalyst.Due to there is certain pushing when sanding gear works
Operation, the poor fluidity of unhardened sand grains, it is difficult to by simply toppling over removal.But applying certain frequency vibrations can break
The accumulation of sand grains, makes sand grains regain mobility.In the present invention, vibration motor is fixed together with sand mold, sand mold
Occur to shake with frequency together with vibrations, under shock effect, sand grains is flowed along gravity direction.It is downward that sand mold is turned into quicksand hole
Direction, sand grains will be discharged by quicksand hole, and through hose, the hollow cavity of connecting shaft, Y shafts under the action of negative inspiratory pressure
Hollow cavity be sucked out and recycle, realize sand mold in extra loose sand grains lasting cleaning.
Rotation auxiliary
Due to about 2000 times of the density that the density of sand grains is air, compressed air cannot effectively transport sand grains, so nothing
By being during vibrations or negative-pressure ward process, sand grains tends to move along gravity direction, for the sand of constant bearing
Type, negative-pressure ward process can cause sand grains to be deposited in partial structurtes, the especially sand mold of inner-cavity structure complexity, thus vibrations with
Cooperation rotation is beneficial to avoid the deposition of sand grains during negative-pressure ward, and all sand grains are smoothly cleared.This practicality
Novel equipment has two groups of independent rotation axis, can meet all dimensional orientations and rotation path of sand mold, complete to realize
Orientation, the quick sand removal process of mechanization.
