PATTERNLESS SAND MOLD AND CORE FORMATION FOR RAPID CASTING

摘要

A method of creating a sand mold for rapid casting including the steps of determining a mold shape providing a generally uniform thickness layer of sand curing at least a portion of the layer of sand machining the cured portions of the layer of sand based on the desired mold shape and repeating the layer forming curing and machining steps until the sand mold is complete. Another aspect includes a machine for creating the sand mold having a build envelope defined by side walls a movable build platform and at least one movable tool assembly the movable tool assembly having a single or plurality of tools chosen from the group consisting of a sand dispenser a sand leveling device a curing device and a machining device.
