Device and process for hot air jet dewaxing and reclaiming wax composition from pattern for casting shell making

A device for hot air jet dewaxing and reclaiming wax composition from a pattern for investment casting shell making, the device comprising:

• 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,
• wherein an investment casting shell is fixedly installed on the bearing platform, a hot air outlet end of the hot air supply mechanism being in fluid communication with a hot air inlet end of the hot air jet dewaxing mechanism, a hot air outlet end of the hot air jet dewaxing mechanism extending into a cavity of the investment casting shell and facing a wax mold;
• wherein the hot air has a temperature within a range of 120 to 170° C.;
• wherein liquid wax generated in the cavity of the investment casting shell is configured to flow into a liquid wax inlet end of the liquid wax collection mechanism under gravity, and
• wherein a liquid wax outlet end of the liquid wax collection mechanism is in fluid communication with a liquid wax inlet end of the liquid wax reclaiming mechanism.
