Problems solved by technology

[0006] The invention provides a drying method for 3D printing sand molds, which solves the problems of low efficiency of traditional thermal drying, difficulty in controlling the drying temperature and time of traditional thermal drying, and the existence of "endogenous and external coke". As well as the problem that the traditional thermal drying has residual temperature and continuous heating process on the sand mold, which seriously damages the strength of the sand mold.

Abstract

The invention discloses a drying method for a 3D printed sand mold. A 3D printer is used for printing the sand mold, then the sand mold is put into microwave drying equipment to be dried, and then the sand mold is verified. Therefore the overall efficiency of the 3D printing technology applied in the field of casting of sand molds is improved, and it is guaranteed that the quality of the sand molds is not affected by the drying process.

Description

technical field [0001] The invention relates to the technical field of 3D printing, and in particular designs a drying method for 3D printing sand molds. Background technique [0002] 3D printing is a rapid prototyping method, and microwave drying is a rapid drying technology. If the two can be effectively combined, they will be a perfect match, and both can reflect the characteristics of rapidity. [0003] The application of 3D printing technology in the field of casting sand mold printing has been gradually promoted, but regardless of the use of furan resin or phenolic resin, sand molds and sand cores can be dried to increase their strength and air permeability, and reduce the amount of gas generated during the pouring process , to ensure the quality of the casting, so the sand mold after printing needs to be dried. However, due to the different materials used for modeling and core making and the different sizes, the drying process is also different. In the prior art, sa...
