Abstract

The invention provides a manufacturing method of a mold for 3D printing of a sand mold. The manufacturing method comprises the following steps: carrying out three-dimensional design on the mold, and preparing the mold by adopting a sand mold 3D printer; subjecting the printed mold for the sand mold to infiltrating with a reinforcing liquid; and subjecting the mold to numerical control cutting machining to obtain a qualified mold. According to the manufacturing method, structural adaptability is high, weight is light, the casting and machining links of a traditional metal mold are omitted, rapid and low-cost manufacturing of the mold for sand mold casting is achieved, and the manufacturing method can be used for small-batch to medium-batch casting production.

Description

technical field [0001] The invention belongs to the field of sand casting, and relates to a method for manufacturing a 3D printed sand mold. Background technique [0002] In the casting production engineering, the quality of the mold and the manufacturing process have a great influence on the efficiency and quality of the casting production. Traditional sand casting molds are mostly made of metal. It is necessary to cast the mold blank first, and then use CNC machine tools to cut or mill the molding surface. This method is a traditional mold manufacturing method, which requires high machining accuracy, long manufacturing cycle, and high mold manufacturing costs, which cannot meet the production needs of small batches and rapid trial production in the aviation and aerospace fields. At the same time, the metal mold is heavy, the labor intensity of the workers is high, and it is easy to deform after long-term use. Contents of the invention [0003] In order to overcome the ...
