System and method for manufacturing a ceramic mold that maintains the dimensions of the resulting cast part
By additively manufacturing the core and shell structures of ceramic molds and connecting them with pins after firing, the problem of movement of the shell and core structures during the firing process was solved, thus achieving dimensional stability of the cast parts and integrity of the cooling channels.

AI Technical Summary
Technical Problem
During the firing process of additive manufacturing ceramic molds, the movement or deflection between the shell and core structures causes deformation of the cooling channels, affecting the dimensional stability of the cast parts.
Method used
The first and second parts of the ceramic mold are manufactured by additive manufacturing, including the body of the core structure and the tip cap. After firing, the shell and the core structure are connected by pins to ensure dimensional stability during the firing process.
Benefits of technology
It effectively prevents the shell and core structures from moving during the firing process, ensuring the dimensional consistency of the cast parts and the integrity of the cooling channels.
