Abstract

The invention discloses a 3D printing graphite contoured chill and a preparation method thereof, and relates to 3D printing forming methods. The 3D printing graphite contoured chill and the preparation method thereof are characterized in that inorganic modified water glass is treated as an adhering agent; an organic ester curing agent is treated as a hardening agent; graphite powder is treated asa printing forming material; a three-dimensional design contoured chill model document is input a 3D printer; a powder bed based three-dimensional jet printing (3DP) technology is carried out to printa three-dimensional entity in a multi-layer overlapping manner so as to obtain a primary graphite contoured chill blank; the primary graphite contoured chill blank is fully cured and roasted to obtain the 3D printing graphite contoured chill product. The formation technology is simple; industrial production is easily carried out; the market prospect is wide; the problems of cumbersome manufacturing process of the contoured chill in casting, difficult numerical control processing and short production period can be solved; in addition, the graphite chill chilling effect is good, so that a castcan be prevented from chill adhering and air pore defects; the production cost is decreased; the cast yield and the production efficiency can be improved; in addition, an organic adhering agent is applied to the 3D printing technology, the performance is stable, the energy is saved, the environment is protected, and the production cost is low.

Description

technical field [0001] The invention relates to a 3D printing forming method, in particular to a 3D printing graphite forming cold iron and a preparation method thereof. Background technique [0002] At present, 3D printing technology has been widely used in various fields such as industrial design, machinery manufacturing, medical equipment and aerospace. 3D printing technology, also known as additive manufacturing technology, is a digital rapid prototyping technology based on digital model files. It uses powdered metal, non-metal and other bondable materials, and the matching binder and hardener , through 3D printing equipment, the object is constructed by layer-by-layer superposition printing. In particular, the use of 3D printing technology to print sand cores has gradually become popular in the foundry industry and has received good technical results. [0003] In the pouring process of ductile iron and steel castings, due to the large solidification and shrinkage of t...
