After cloth completes, controlling laser printing 12 and print on sand face, laser printing 12 is in control system
Under control, being scanned along setting track, first scan the most individual profile band and form sand mold hardening zone, scan wheel profile is i.e. the most again
Cutting, the temperature of scanning sand mold hardening zone is close to the solidification temperature of sand, and the temperature of scan incision line consolidating much larger than sand
Change temperature, make the sand at cut-off rule lose efficacy, form the inefficacy cut-off rule consistent with contour line, by laser printing 12 dozens
Sand at the contour line of print is then become loose sand by solid state, and middle sand mold hardening zone is then solidification sand, and monolayer prints complete
After, hopper 13, push away sand plate 14 and laser printing 12 all returns in situ, then lowering or hoisting gear controls hoistable platform 5 and moves down one
The thickness of layer of sand, then repeats cloth next time, pushes away the process of sand and printing, until sand mold has printed.
Being provided with between printing equipment with drying unit and be connected track 18, the sand mold printed is sent on connection track 18
Enter described drying unit, sand mold moving vehicle 6 be positioned at connection track 18 on, by sand mold moving vehicle 18 by support 7, sanding platform 8,
Casing 11 and sand mold associated movement are in drying unit.Drying unit is drying baker 19, and drying temperature in drying baker 19 is 170 DEG C
～about 200 DEG C, sand solidified at high temperature heat, sand mold separates for boundary with the three-D profile losing consolidation performance, obtains
Sand mold needed for end.
This utility model, by the way of layering prints, uses above-mentioned 3D printer can print various sizes and complexity
The sand mold of curved surface, applied widely.And when using the printing of above-mentioned dress to put every layer of sand face, laser printing 12 run trace is sand mold
Contour line, walking path is short, and working (finishing) area is little, can be effectively improved shaping speed and efficiency, and stamp with the size can strictly control, and makes
Profiled member dimensional accuracy is high.And after sand casting purposes completes, carry out high-temperature heating and just sand mold can be reduced into loose sand, reclaim
Utilize, escapable cost.
Above example is only in order to illustrate the technical solution of the utility model and unrestricted, although with reference to preferred embodiment pair
This utility model has been described in detail, and it will be appreciated by those skilled in the art that and can enter the technical solution of the utility model
Row amendment or equivalent, without deviating from objective and the scope of the technical program, it all should be contained in power of the present utility model
In profit claimed range.
