Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the A-A views of Fig. 1 of the present invention.
Fig. 3 is the structure diagram of Material collecting box for harvesting of the present invention.
Embodiment
The embodiment of the present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1,2 and 3, sand mold of the invention makes and uses laser 3D printing platform, it is characterised in that including base 8,
Column 7 around this base 8 is set, the hanging frame 14 at the top of this column 7, the liter being arranged on the base 8 are set
Drop system, sets the shift system above this jacking system, sets the sanding platform 3 on this shift system, is disposed around institute
The curable type sandbox 1 of 3 surrounding of sanding platform is stated, the Material collecting box for harvesting 2 being symmetricly set on 1 biside plate of curable type sandbox, described consolidates
The top of molding sand case 1 is fixedly connected by bolt with the hanging frame 13,
The jacking system includes hoistable platform 9, the lifting gear being connected with this hoistable platform 9, the lifting
Device includes screw lifter 11 and servomotor 10, and the screw lifter 11 is connected with the hoistable platform 9,
The shift system includes sand mold moving vehicle 6, sets the sand mold base support 5 on this sand mold moving vehicle 6, if
The sand mold base assembly 4 at the top of this sand mold base support 5 is put, the sanding platform 3 is arranged on the sand mold base group
On part 4, the sand mold moving vehicle 6 is arranged on the hoistable platform 9.
It is equipped with the base 8 and is oriented to optical axis 12, the hoistable platform 9 is socketed on the guiding optical axis 12,
And moved up and down along the guiding optical axis 12.
The Material collecting box for harvesting 2 includes two infundibulate hoppers for being bolted on the 1 side plate top of curable type sandbox
15, it is separately positioned on the flow control valve 13 of this two 15 outlet at bottom of infundibulate hopper.
The flow control valve 13 is ball valve.
The curable type sandbox 1 is fixed by four sides boxboard with bolt assembly to be formed.
1 height of curable type sandbox is 700mm-800mm.
When print platform works, hoistable platform 9 is controlled to be moved up and down along optical axis 12 is oriented to by servomotor 10, hoistable platform
9 when rising, and whole shift system and sanding platform 3 are pushed into curable type sandbox 1, in 3 upper berth sand filling of sanding platform, using swashing
Optical printer head successively prints on sand；Since curable type sandbox 1 is the board-like babinet of overall steel, 1 height of curable type sandbox is 700mm-
800mm, prevents sand material loose sand, improves sand material bond quality to ensure the consolidation shaping of sand mold workpiece area sand material, takes up sand part side
Just sand part is transported；The feeding device of 3D printer is constantly to successively sanding on sanding platform 3, laser printing head work by setup program
Make, form mould surface hardening, press part section pattern cut on layer of sand surface, often cut one layer, 11 work of screw lifter
