Preparing a salt core for the formation of cavities in a light-metal die-casting, comprises introducing a paste-like salt-liquid mixture into cavity of compression mold, and compressing the mixture to expel fluid contained in the mixture

摘要

Preparing a salt core, comprises: providing a multi-part compression mold (110) comprising a cavity (111) having a negative contour of the salt core; introducing a paste-like salt-liquid mixture (M) into the cavity of the compression mold, to which the paste-like salt-liquid mixture is placed at a location of the cavity in precise doses by a metering device (120); closing the compression mold and compressing the paste-like salt-liquid mixture in the cavity in order to expel fluid contained in the paste-like salt-liquid mixture; and opening the compression mold and removing the salt core.
