TECHNICAL FIELD

[0001] The utility model relates to foundry technology field, concretely is a lost foam drying device for foundry production. BACKGROUND

[0002] Lost foam casting, also known as precision casting or investment casting, is a mold-making technique that is eliminated or "lost" during the manufacturing process. In this process, a wax or dissolvable pattern is used as a mold. Around this pattern, a clay shell is formed. Then, through heating, the wax or dissolvable material is melted and removed from the shell, leaving an empty pattern into which metal or other materials can be poured. This technique allows for very fine details and complex shapes in the castings.

[0003] In this process, drying is a very important step. The purpose of drying is to ensure that the pattern is completely dry to prevent water vapor from being produced when the molten material is poured, which can cause defects in the casting. Drying also helps to enhance the strength of the pattern so that it can resist the pressure of the molten material. And after the lost foam processing is completed, the paint on its surface also needs to be dried.

[0004] The existing lost foam for casting needs to be manually dried on its surface or left to dry in a dry environment during the processing process, which has low drying efficiency and is not conducive to improving the processing efficiency of the lost foam casting. SUMMARY
