This invention relates to the field of sand casting technology and discloses an integrated mechanism and process for impregnation, coating, and drying of sand casting cores. The mechanism includes an integrated impregnation, coating, and drying machine. A support platform is installed inside the machine, and a base block is installed on top of the support platform. A mold core is bolted to the top of the base block. This integrated mechanism utilizes a limiting component. When the bolts loosen, the threaded column moves upward along the connecting column and the strip groove, driving the slider upward synchronously. This pushes the movable rod outward, causing the moving block to slide along the strip block towards the limiting column. An insert plate is inserted into the surface of the limiting column to form a radial lock.

This, combined with the axial limiting of the limiting column, prevents the bolts from loosening, rotating, or coming out. This prevents the mold core from shifting or failing during impregnation and drying, significantly improving assembly firmness, operational stability, and core forming quality.
