Abstract

The invention provides a 3D printing sand mould which comprises an inner-layer sand mould and an outer-layer sand mould. The inner-layer sand mould is provided with an inner surface where a casting is molded, and an outer surface opposite to the inner surface, wherein the inner-layer sand mould is contained inside the outer-layer sand mould, and the inner-layer sand mould is connected with the outer-layer sand mould through a middle-layer sand mould; and the middle-layer sand mould comprises a plurality of column zones and solid zones arranged between adjacent column zones in a filling manner, each column zone comprises a plurality of cylindrical rings which extend in the axial direction and are connected with each other in the radial direction, one end of each column zone in the axial direction is connected with the outer surface, and the other end of each column zone in the axial direction is connected with the outer-layer sand mould. The invention further provides a method for manufacturing the above sand mould. The 3D printing sand mould aims at reducing the cost for printing the 3D printing sand mould, shortening the period for printing the 3D printing sand mould, and guaranteeing the whole intensity and stability of the 3D printing sand mould.

Description

technical field [0001] The invention relates to the technical field of 3D printing sand casting production, more specifically, to a 3D printing sand mold and a manufacturing method thereof. Background technique [0002] 3D printing (3D printing, that is, three-dimensional printing) is a kind of rapid prototyping technology. It is based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. Technology. [0003] With the promotion and application of 3D printing technology, the current method of using 3D printing sand molds for casting production has gradually become popular in the industry. This 3D printing sand mold production method can replace the traditional manual mold molding process. The resulting sand mold has a compressive strength twice that of the manual sand mold. At the same time, it can be directly printed to form various complex sand mold structures, with extremely high formability ...
