Sand mould 3D rapid molding equipment using slab printer

Abstract

The invention discloses sand mould 3D rapid molding equipment using a slab printer. The sand mould 3D rapid molding equipment comprises an outer frame, an inner frame, a scraper mechanism, the slab printer, a sand feeding box, a molding sand box, a recovering hopper, a first Z-direction mechanism, a second Z-direction mechanism, a platform plate and a spraying nozzle; the bottoms of the inner frame and the outer frame are connected, two longitudinal beams are arranged at the upper end of the outer frame in parallel, and a side surrounding plate is arranged on the side face of the outer frame;the scraper mechanism is connected with the lower portion of the back end of the slab printer, the platform plate is connected with the upper end of the inner frame, the sand feeding box is connectedwith the platform plate, the molding sand box is connected with the platform plate, the recovering hopper is connected with the molding sand box, a first piston plate is arranged in the sand feeding box, and a second piston plate is arranged in the molding sand box; and the middle portion of the first Z-direction mechanism is connected with the platform plate, the top end of the first Z-directionmechanism is connected with the first piston plate, the middle portion of the second Z-direction mechanism is connected with the platform plate, the top end of the second Z-direction mechanism is connected with the second piston plate, a spraying nozzle support is arranged on the side face of the spraying nozzle, the spraying nozzle is connected with the slab printer through the spraying nozzle support, powder paving is carried out layer by layer, the spraying nozzle sprays out binders, and layer-by-layer printing is achieved.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, in particular, the invention relates to a sand mold 3D rapid prototyping device using a flatbed printer. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond materials, which create three-dimensional objects by printing layers of adhesive materials. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. [0003] The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are ...
