[0002] At present, the manufacturing process combining 3D printing model with precision casting process is the most advanced in the current precision casting process. The dewaxing process of 3D printing model is very complicated, with both wax liquid and 3D printing mold material, so it is very necessary to separate the two types of substances.
[0003] The dewaxing temperature of the dewaxing process is 140-160℃, and the melting point of 3D printing materials is 160-180℃. Therefore, after dewaxing, the 3D printing materials will mix with the wax liquid and flow out. Moreover, the 3D printing materials are insoluble in the wax liquid and water, and form small blocks or large particles. If they are not separated, they will block the wax delivery pipeline. The small particles will mix in the wax liquid and continue to block the nozzle of the wax gun, causing the wax liquid to be scrapped or blocking the wax delivery pipe. Therefore, we propose a 3D printing model dewaxing device to solve the above problems. Utility Model Content
