Abstract
A device and process for hot air jet dewaxing and reclaiming wax composition from patter for investment casting shell making. The device includes a hot air supply mechanism, a hot air jet dewaxing mechanism, a liquid wax collection mechanism, a liquid wax reclaiming mechanism, and a bearing platform. A shell for investment casting is installed on the bearing platform. A hot air outlet end of the hot air supply mechanism is in fluid communication with a hot air inlet end of the hot air jet dewaxing mechanism, and an injector connected with hot air outlet end of the hot air jet dewaxing mechanism extends into a cavity of the shell and faces the body of a wax pattern. Liquid wax generated in the cavity of the shell flows under the action of self-gravity into the liquid wax collection mechanism from its liquid wax inlet end.
