Description
Technical field
The present invention relates to casting industry sand wicking surface processing technology field, more particularly, to a kind of 3D printing sand mold continous way
The automatic sand cleaning machine in six faces, while it is related to a kind of automatic sand removal method in face of 3D printing sand mold continous way six.
Background technology
In casting field, when carrying out sand casting using traditional handicraft, with carrying for cast shape complex degree of structure
Height, casting mold are more difficult；And the Digitized manufacturing pattern using 3D printing technique as representative, can using one-shaping technique
The casting structure of complexity is printed according to computer design figure, so as to reach saving material, shortens the lead time of parts, is reduced
The purpose of manufacturing cost.Therefore, domestic and international increasing sand casting enterprise, especially accept high-end intricate casting manufacture and add
The foundry enterprise of work, introduce the manufacture that 3D printing technique is used for intricate casting sand mold.With 3D printing technique commercial application
The expansion of scope, gradually it is found that some urgently improved technical problems, such as mould surface automation sand removal.
Traditional sand mold is formed by metal pattern compacting, and intensity is high, and surface is smooth, and sand mold is directly entered stream after completing
The next procedures such as painting, dry tack free.And when using 3D technology printing sand mold, first according to production requirement in computer end typing sand mold
Threedimensional model, then entered repeatedly according to the order of one layer of dry sand, one layer of resin curing agent according to threedimensional model by 3D printer
Row printing, is finally completed the manufacture of sand mold.Process characteristic based on 3D printing, 3D sand mold intensity is relatively low, and the sand mold after shaping
Surface have one layer of about 10mm it is thick, there is the floating layer of sand of certain viscosity, therefore equally directly enter without image of Buddha conventional metals sand mold
Row surface flow coat carries out desanding dedusting, it is necessary to first pass through sand removal technique, carries out flow coat again afterwards.Specifically, take to use first and add
Hot equipment is heating and curing to 3D sand molds, is transported to hoisting mechanism in single sand removal room carries out artificial sand removal afterwards, clearly
Flow coat station is transported to after the completion of sand again and carries out surface flow coat operation.
Above method transhipment time is grown, and sand mold breakage easily occurs in transport process；Artificial sand removal dust is more, noise
Greatly, efficiency is low, and not only labor intensity is big, and operating environment is poor, has a strong impact on employee's health；In addition, because 3D printing
Product is mostly the product of labyrinth, and in order to prevent sand removal dead angle, it is necessary to which sand mold constantly to be lifted to upset, fit with nozzle is entered
Row purging.Problem above has seriously govern commercial application of the 3D printing technique in casting field.
The content of the invention
In order to solve the above problems, the present invention provides a kind of automatic sand cleaning machine in face of 3D printing sand mold continous way six, carries simultaneously

A kind of automatic sand removal method in face of 3D printing sand mold continous way six, it is automatic using above-mentioned six faces of 3D printing sand mold continous way
Sand cleaning machine, specific steps include：
The first step, sand mold is sent into sand cleaning machine housing by roller conveyor, and made under sand mold is located at lift blast cover just
Side, close import closing door and outlet closing door；
Second step, make to drop down onto around sand mold under lift blast cover, open deduster, and the unlatching of magnetic valve is controlled by PLC
Order and opening time, the blow gun on blast cover and/or bottom blowing frame is carried out the face of space six to sand mold and purge, sand in purge
The floating sand on type surface is fallen into portable silt box, and caused floating dust enters deduster by dust shield；
3rd step, import closing door and outlet closing door are opened, lift blast cover is gone up to original position, then sand mold is sent into down
One station carries out human assistance purging, so as to complete whole sand removal process.
The automatic sand cleaning machine in face of 3D printing sand mold continous way six provided by the invention, it can be used in extensive, pipelining
The automation sand removal production of 3D printing sand mold, its is simple in construction, easy to operate, and it is clear to carry out sand mold using sand cleaning machine provided by the invention
During sand processing, easily there is the damaged phenomenon of sand mold when can realize the automatic continuous transhipment of sand mold, reduce artificial carry and hoist,
The automatic blast in the face of space six can be carried out to it according to the concrete structure of sand mold, while collect knockout and airborne dust, not only increased
The automaticity of sand removal work, is greatly shortened the 3D printing sand mold post-processing time, has good economic benefit, and
The working environment of sand removal process is significantly improved, is beneficial to the health of operating personnel.
