Specific implementation mode

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

As shown in Figure 1, the present embodiment is related to a kind of main body driving structure of 3D printer comprising integral frame structure and Two-way sanding print module, the two-way sanding print module are mounted in integral frame structure；The general frame knot Structure includes two parallel crossbeams 1 and metal framework 3；Metal framework 3 is rectangular parallelepiped structure, is fixedly mounted on 1 lower section of crossbeam；Institute The two-way sanding print module stated includes printing beam 5, the first sanding beam 4, the second sanding beam 6 and printing head 7；The printing The both ends of beam 5 are separately mounted to be slidably connected on two crossbeams 1 and with crossbeam 1, and the first sanding beam 4, the second sanding beam 6 are pacified respectively Mounted in the left and right sides of printing beam 5, printing beam 5 is equipped with multiple printing heads 7.1 lower section of crossbeam is equipped with print platform 2, printing The top surface area of platform 2 is equal to the bottom area of metal framework 3.

As shown in Figures 2 to 5, the operation principle of the main body driving structure of 3D printer is：

Before equipment printing, workbench 2 is in the outside of the crossbeam 1 of printing device, with reference to Fig. 2.After opening of device, work Platform 2 is moved to the underface of metal framework 3 from outside to inside, and crossbeam drives metal framework 3 to decline so that workbench 2 is in Inside metal framework, and the top of metal framework 3 is made to move to the upper surface of workbench 2, with reference to Fig. 3；

Under the drive of motor, two-way sanding print module realizes two-way sanding printing operation.Wherein, printing device to When left movement, the first sanding beam 4 starts sanding, and the second sanding beam 6 is closed, and prints the printing head 7 on beam 5 and is sprayed on sand and is glued Mixture, when two-way sanding print module is moved to 2 left end of workbench, equipment has printed one layer.Two-way sanding impression block BOB(beginning of block) counter motion, the first sanding beam 4 are closed, and the second sanding beam 6 starts sanding, and it is dynamic to print the execution of printing head 7 on beam 5 Make, so sanding prints back and forth, referring to Fig. 4.

In print procedure, sand mold is vertically printed along metal framework 3 always, is tilted to collapse to workbench 2 to prevent sand Position in addition.

One layer of sand mold is often printed, the sand mold on workbench 2 rises the distance of a thickness, and corresponding crossbeam 1 drives Metal framework 3 also rises the distance of a thickness, until model printing is completed.After equipment completes sanding printing, crossbeam 1 It drives metal framework 3 to move up, leaves printed sand mould structure, with reference to Fig. 5.Finally, workbench 2 is removed, Take out printed sand mold.

The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases The technical field of pass, is equally included in the patent within the scope of the utility model.
