Abstract
This invention provides a de-molding system of ceramic parts manufactured by freeze-casting comprising a mold (9), wherein the mold (9) comprises an upper opening (95) and a lower opening (94), wherein the upper opening (95) is adapted to receive a colloidal suspension (92), and one of the openings is adapted to allow the passage of a manufactured ceramic part (92), characterized by comprising at least one main de-molding element (80) adapted to actuate a ceramic part manufactured (92) through an opening in the mold (9).In addition, the invention provides a mold cooling system for the manufacturing of ceramic parts by freeze-casting comprising: a source (1) of cooling gas; a cooling gas cooling medium (7) fluidically connected to the cooling gas source (1); and a cooling cell (5), fluidly connected to the cooling gas cooling medium (7), comprising a mold (9) in its interior, wherein the cooling cell (5) comprises a refrigerated cooling gas injection opening. Thus, a mold cooling system is provided for the manufacturing of ceramic parts by freeze-casting comprising the stages of: refrigerating a cooling gas coming from a cooling gas source (1); and injecting a cooling gas that is re…
