Problems solved by technology

The tamped graphite type is mainly manually tamped according to the graphite type drawing, and then baked or vacuum degassed, and then assembled for casting molding. Although the preparation of the above casting mold can relatively guarantee the Dimensional accuracy and material saving, thereby controlling production costs, but the labor cost in the process is high and the production efficiency is low

Abstract

The invention discloses a 3D printing system based on a titanium and titanium alloy casting sand mold. The 3D printing system comprises a control component and printing equipment. The control component is connected with the printing equipment and controls the printing equipment to complete printing action. The printing equipment comprises a printing base, a printing platform, a row orientation support, a printing nozzle and a printing material. The printing base is provided with a four-axis movement mechanism. The printing platform is arranged on the printing base through the four-axis movement mechanism. The row orientation support is fixedly installed on the printing base. The printing nozzle is arranged on the row orientation support and can move relative to the row orientation support. The 3D printing system is simple in structure and easy to operate. The casting sand mold is manufactured through 3D printing, so that the manufacturing time of the sand mold is greatly shortened, production efficiency is improved, and meanwhile labor cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a graphite type 3D printing system based on titanium and titanium alloy castings. Background technique [0002] Since titanium and titanium alloy materials have the characteristics of low density, high strength ratio, strong corrosion resistance, and small linear expansion coefficient, the titanium industry has developed rapidly since the 1950s under the urgent need of aerospace technology. Now, titanium and titanium alloys are not only indispensable structural materials in the aerospace industry, but also widely used in shipbuilding, chemical industry, metallurgy, and medical treatment. [0003] In the casting process of titanium and titanium alloys, due to its high chemical activity, it is prone to violent chemical reactions with conventional casting molding materials at high temperatures, which affects the performance of molded castings. Graphite has high temperature resis...
