Problems solved by technology

This method has the disadvantage of low efficiency because the printing of each layer requires three processes of sanding, printing, and lowering of the table in sequence, so the printing process is intermittent rather than continuous motion.

Abstract

The invention provides a rotary type sand mold three-dimensional printer and belongs to the technical field of sand mold three-dimensional printing. The rotary type sand mold three-dimensional printer comprises a base, a working cylinder, an axial contact bearing, a workbench, connecting rod mechanisms, a lead screw nut, a hollow rod, a lead screw, a sand laying bin, a printing head moving mechanism and a support. The working cylinder and the workbench are connected through a set of connecting rod mechanisms. The hollow rod provided with the lead screw nut is fixedly connected with the workbench and connected with the base through the lead screw. The sand laying bin and the printing head moving mechanism are located at the top of the working cylinder and fixedly connected with the base through the support. By the adoption of the rotary type sand mold three-dimensional printer, a workbench rotating manner can be used for conducting the sand laying process, the printing process and the workbench descending process at the same time, so that the machining time is shortened, and efficiency is improved. The rotary type sand mold three-dimensional printer is reasonable in design, simple in structure and suitable for optimization design of sand mold three-dimensional printers.

Description

technical field [0001] The invention relates to a printer in the technical field of sand mold three-dimensional printing, in particular to a rotary sand mold three-dimensional printer capable of simultaneously performing the processes of laying sand, printing and lowering a workbench. Background technique [0002] Three-dimensional printers, also known as three-dimensional printers, are a rapid prototyping process that produces three-dimensional models layer by layer. Its operation process is similar to that of traditional printers, except that traditional printers print ink onto paper to form Two-dimensional plane drawings, while three-dimensional printers stack liquid photosensitive resin materials, molten plastic filaments, gypsum powder and other materials by spraying binders or extruding to form three-dimensional entities. [0003] In the existing technology, the moldless sand mold manufacturing technology based on the principle of 3D printing works by first laying a th...
