Abstract

The invention discloses a composite 3D printing preparation method of a casting sand mold with a chilling block and the casting sand mold in order to solve the problems that in an existing 3D printing sand mold casting model in the prior art, the chilling block is inconvenient to install, and the cost is high. The method comprises the following steps that a 3D printing process is adopted, and a 3D printing sand mold is manufactured according to a product drawing; a wire rod 3D printing process is adopted, a 3D printing wire rod shell mold is manufactured according to the same product drawing, and the 3D printing wire rod shell mold is matched with the 3D printing sand mold; the 3D printing sand mold and the 3D printing wire shell mold are assembled, and a chilling block cavity is formed in a gap between the 3D printing sand mold and the 3D printing wire shell mold; adding a chromite sand mixture into the chilling block cavity, and compacting and curing the chromite sand mixture to form the chilling block; and the 3D printing wire shell mold is removed, and the casting sand mold with the chilling block is obtained after treatment. According to the 3D printing sand mold, the chillers in any positions and any shapes can be arranged, the manufacturing cost is reduced, and the application range of the 3D printing sand mold is widened.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a composite 3D printing preparation method of a casting sand mold with chilled iron and the casting sand mold. Background technique [0002] 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 method of 3D printing to produce sand molds can replace the traditional wood mold modeling process. The obtained sand mold has a compressive strength that is twice that of wood mold sand molds. At the same time, various complex sand mold structures can be directly printed and formed. It has extremely high reliability. Formability. [0003] When the casting is cooled and solidified in the 3D printed sand casting model, the final solidified part is also prone to defects such as shrinkage porosity and shrinkage cavity, which seriously affects the quality of the...
