Description
Technical field
3D printing field is the utility model is related to, particularly a kind of sand mold 3D printing old sand processing unit.
Background technology
Sand mold 3D printing operation principle is first to mix foundry quartz sand and curing agent, and one layer of sand is spread in print platform
Afterwards, for printhead according to this layer of sand core contour feature sprayed resin bonding agent on layer of sand, such sanding, sprayed resin are anti-layer by layer
Multiple accumulation bonding, required sand core entity is ultimately formed, is taken out after air set from work box, surface is cleaned out and floats sand i.e.
Produced available for casting.
Because the contour shape by printing core, quantity etc. influence, sand can not possibly be fully utilized in print job case, printing
Into sand core.The sand that this part does not have blown resin is just cleaned out during finished product sand core is taken out, and is turned into " old sand ".It is old
Although sand can reclaim, it can mix in fresh sand continue printing use in a short time, the proportional quantity of old sand and fresh sand can not
More than 2:8, sanding quality otherwise can be influenceed, reduces the performances such as intensity, the surface quality of printing core, therefore old sand utilization rate is very
It is low, it is mostly in idle state.The other old sand accumulation time too long, the easy moisture absorption, lumps, is mixed into other impurities etc., it is impossible to
Match and use with fresh sand again, so that as the extension of printer working time, the amount of saving bit by bit of the old sand of recovery are more and more.
Summarized and found according to the actual printing condition of production, the average sand core printing occupation rate of work box 55% or so,
That is one action case is often made it is necessary to produce the printing old sand of nearly half chests.These printings are very high with roughing sand quality requirement,
All it is to come from external import, cost is 10 times of domestic conventional cast sand, if by old sand waste treatment, is not only exacerbated
Operation cost is printed, resource is wasted, environment is caused necessarily to pollute.
Because in consideration of it, special propose this utility model.
