COMPOSITE CERAMIC MOLD, METHOD FOR MANUFACTURE OF COMPOSITE CERAMIC MOLD AND DEVICE FOR ITS REALIZATION Russian patent published in 1994 - IPC

FIELD: foundry. SUBSTANCE: the offered series of inventions concerning the manufacture of ceramic molds provides for production of supporting parts and constant patterns and their combined assembly, filling with fluid flow ceramic suspension of gaps formed between lined surfaces of supporting parts and shape forming surfaces of constant patterns and filling vertical channels made in supporting parts, hardening of fluid flow ceramic suspension, separation of supporting parts lined with ceramic from constant patterns, removal of volatile matter and calcination of ceramics together with supporting parts and removal of ceramics from hollows of filling vertical channels up to residual height in zone of base of said channels equally 0.1-2.0 of thickness of ceramic lining layer on shape-forming surface of supporting part. EFFECT: higher efficiency. 3 cl, 13 dwg, 1 tbl
