A sand lifting device for 3D printing

Abstract

The invention relates to the technical field of 3D printing, and discloses a sand lifting device for 3D printing, which includes supporting legs, a stirring device is fixedly connected to the top of the supporting legs, and a lower hopper is arranged in the middle of the lower surface of the stirring device , the middle part of the lower surface of the lower hopper is connected with a discharge pipe, and the bottom end of the discharge pipe is connected with a material guide pipe. The sand lifting device for 3D printing realizes the rapid mixing of sand and catalyst through the mixing device, speeds up the mixing speed of sand and catalyst, improves the work efficiency, and realizes the dispersion of mixed sand through the stirring device. The sand and catalyst inside the mixing device are heated by the electric heating tube, which reduces the degree of adhesion of the catalyst to the sand, reduces the probability of sand agglomeration, ensures the fluidity of the sand, and avoids the excessive volume of the sand from blocking the conveying material. The hose will affect the normal use of the sand lifting device.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a sand lifting device for 3D printing. Background technique [0002] 3D printing technology is also called rapid prototyping manufacturing technology. Its basic principle is to repeatedly print a certain thickness of material on the platform and repeat it until the entire molded part is generated. The process engineering is to use 3D modeling software to create a 3D solid shape, and then The designed physical shape is discrete and layered through the processing software of the rapid prototyping equipment, and then the processed data is input into the equipment for manufacturing, and finally a certain post-processing is required to obtain the final product; the current 3D sand mold printer nozzle jetting The most important thing is resin, and the bonded object is sand, among which, the sand is mixed with a catalyst, and the resin sprayed on the sand surface will quickly solidi...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a sand lifting device for 3D printing, which solves the problem that the sand of the sand lifting device in the prior art has good fluidity before the catalyst is not mixed in, but after mixing, the fluidity is poor. Reduction, even agglomeration phenomenon, affecting the problem of sand transportation
