Description

Technical Field

[0001] This utility model belongs to the field of sand shell drying technology, specifically relating to a casting sand shell drying device. Background Technology

[0002] In the field of investment casting, the investment mold is generally made of paraffin wax, which has a melting temperature of 60-70℃. After the sand shell is attached to the outside of the wax model, the sand shell needs to be dried and then placed in a hardening bath for hardening. Finally, the wax model needs to be melted, which is commonly known as lost-wax casting. This process usually involves placing the model with the attached sand shell into a hot water bath to melt the paraffin wax. Then the sand shell is removed for post-processing, which includes first drying the sand shell and then firing it at high temperature.

[0003] In existing related technologies, when using sand shell drying devices, the wax mold is heated inside the chamber by electric heating components. The air discharged after heating still contains residual heat, but it will carry a lot of moisture after contacting the wax mold, making it unusable. It is often directly discharged through the dehumidification port, which inevitably wastes heat energy and is not conducive to energy conservation and environmental protection. Therefore, it is urgent to design a casting sand shell drying device to deal with these problems. Utility Model Content
