Laser 3D printing platform for manufacturing cast sand mold

Abstract

The invention discloses a laser 3D printing platform for manufacturing a cast sand mold. The laser 3D printing platform comprises a vacuum loading device, a coaxial powder sending device, a movement guide rails, a sand mold manufacturing platform, a sand mold shifting vehicle and a lifting device; for the vacuum loading device, sands are conveyed into a laser 3D printer through a vacuum pump and is conveyed to the coaxial powder sending device through a vacuum loading pipe and a sand conveying pipe; the vacuum loading device is connected with the coaxial powder sending device and is arranged above the whole structure; the coaxial powder sending device directly prints the sand mold on the sand mold manufacturing platform; the lifting device is connected with the sand mold manufacturing platform through the sand mold shifting vehicle to control lifting of the sand mold manufacturing platform and realize printing layer by layer; and the sand mold shifting vehicle conveys the printed sandmold into a next procedure for continuous work. For the laser 3D printing platform provided by the invention, by controlling the coaxial powder sending device and the lifting platform, layer-by-layerprinting of the 3D printer is ensured, and sand mold manufacturing is realized; and then the cast sand mold is moved out of the printer, so that next work can be ensured to be performed.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a laser 3D printing platform for making casting sand molds. Background technique [0002] 3D printing technology is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing, and is often used in mold manufacturing, industrial design and other fields. Model. The traditional sand mold making is to make the wooden or metal mold of the parts first, and then make the sand mold based on the wooden or metal mold of the parts. In this way, in the early stage of production, if the process and shape need to be changed during the sand mold inspection, it must be Modify or redo the wood and metal molds of the parts, so that the sand molds can be mass-produced after repeated verifications. This process takes a long time, resulting in a prolongation of the production cycle o...

The traditional sand mold making is to make the wooden or metal mold of the parts first, and then make the sand mold based on the wooden or metal mold of the parts. In this way, in the early stage of production, if the process and shape need to be changed during the sand mold inspection, it must be Modify or redo the wood and metal molds of the parts, so that the sand molds can be mass-produced after repeated verifications. This process takes a long time, resulting in a prolongation of the production cycle of the parts, which often affects the progress of the entire equipment and increases the cost of the equipment. In addition, the sand mold The working environment of the production is harsh, causing great harm to people
