A feeding device for a small metal mold 3D printer

Abstract

The invention discloses a feeding device for a small-sized metal mold 3D printer, comprising a material receiving pipe, one end of the material receiving pipe is connected with a printing material processing box, and a stirring assembly and an extrusion assembly are respectively arranged in the printing material processing box , the stirring assembly includes a stirring shaft, one end of the stirring shaft runs through the top of the printing material processing box and extends to the outside of the printing material processing box, the stirring shaft is fixedly installed with a motor at one end outside the printing material processing box, the stirring shaft There are four sets of stirring blades in an equidistant array on the surface, and a collar is fixedly installed between the adjacent two sets of stirring blades. The pressing plate is slidably installed in the printing material processing box, and the annular equidistant array on the surface of the pressing plate has four sets The guide rods, wherein one set of the guide rods also pass through the top of the printing material processing box and extend to the outside of the printing material processing box, effectively control the viscosity of the liquid plastic substance before it leads to the spray nozzle.

Description

Technical field [0001] The present invention belongs to the 3D printer technology, and in particular, a small metal mold 3D printer is provided. Background technique [0002] 3D printer is also known as a three-dimensional printer, a machine that accumulate manufacturing technology, a rapid forming technology, is a digital model file, which uses special wax materials, powder metal or plastic, etc. Print a layer of adhesive material to make a three-dimensional object. At present, the three-dimensional printer is used to make products. The technique of constructing the object layer by layer. The principle of the 3D printer is to put the data and raw materials into the 3D printer, and the machine will make a layer layer in accordance with the program. The greatest difference between 3D printers and traditional printers is that "ink" it uses is real raw materials, and there are many variants in the form of stacked thin layers, which can be used for printing media varies, from a wide ...
