Sand mold 3D printer

Abstract

The invention discloses a sand mold 3D printer. The sand mold 3D printer comprises a printing base, cross beams, a ground rail, a sand supplying system, a sand paving beam, a printing beam and workingboxes, wherein the two cross beams are erected on the printing base in parallel, the ground rail is arranged below the cross beams, the sand supplying system is fixed on the cross beams, the two endsof the sand paving beam and the two ends of the printing beam are erected on the cross beams and are in sliding connection with the cross beams, and the working boxes is arranged on the ground rail and is in sliding connection with the ground rail. According to the sand mold 3D printer, the sand supplying system with two sand storage tanks is used for sand supplying, so that the size of equipmentcan be effectively reduced, continuous sand supplying can be ensured; the printing beam and the sand paving beam are driven by a linear motor, so that the operation stability of equipment can be improved, the noise is reduced, the two working boxes are adopted for printing, continuous work of equipment is realized, and the printing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sand mold 3D printing, and in particular relates to a sand mold 3D printer. Background technique [0002] 3D printing technology is also called rapid prototyping manufacturing technology. The basic principle is to repeatedly print a certain thickness of material on the platform, and repeat until the entire molded part is produced. Its process engineering is to use 3D modeling software to create a 3D solid shape, then discrete and layer the designed solid shape through the processing software of the rapid prototyping equipment, and then input the processed data into the equipment for manufacturing, and finally need to carry out certain Post-processing to get the final product. [0003] With the development of 3D printing technology today, its development focus has shifted from 3D printing prototypes to rapid manufacturing and rapid direct manufacturing of metal parts. 3D printing technology is not only ...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing domestic 3D equipment adopts a single large-scale sand supply system, resulting in a large overall size of the 3D equipment. This large-scale 3D printing equipment takes up a lot of space, has low work efficiency and high labor intensity, and cannot meet the requirements of fast and high-efficiency production. need
