[0039] This application provides a preparation method and device for a ceramic shell core for precision casting. This application improves the existing preparation method of a ceramic shell core for precision casting, and divides the ceramic shell core into areas according to the precision requirements and divides each One area is layered and sliced, and then the extrusion head corresponding to the area is set to realize the integrated forming of the ceramic shell and core to obtain a high-precision ceramic shell core. At the same time, the existing forming equipment is improved by setting multiple extrusion heads, and Independent control of multiple extrusion heads not only overcomes the limitation that the existing rapid prototyping technology can only realize single material or mixed extrusion of two materials, but also solves the problem that the extrusion heads cannot be accurately positioned and scratched in the existing technology. The problem of the green body improves ...
