AI Technical Summary
Technical Problem
During the firing process of additive manufacturing ceramic molds, the movement or deflection between the shell structure and the core structure can cause deformation of the cooling channels and core extrusion, affecting the quality of the cast parts.
Method used
By inserting pins into the shell structure of the ceramic mold, the pins contact and fix the core structure in the shell hole formed by additive manufacturing technology, preventing relative movement between the shell and the core during the firing process.
Benefits of technology
Effectively maintain the designed spacing between the shell and core structures to prevent deformation and extrusion, and ensure the dimensional consistency and integrity of the cast parts.
