TECHNICAL FIELD
[0001] The utility model belongs to a kind of investment casting technical field, more specifically, it is particularly related to a kind of baking device of investment casting. BACKGROUND
[0002] Investment casting is also called "lost wax casting". Investment casting usually refers to that easy-melting material is made into mold, several layers of refractory material are coated on the surface of the mold to form a mold shell, and then the mold is melted to discharge the mold shell, so that a casting mold without parting surface is obtained. After high-temperature baking, the casting mold can be poured by sand casting. Since the mold is widely made of wax material, investment casting is often called "lost wax casting". The mold is usually baked in a baking device.
[0003] Based on the above, the present inventors found that the following problems exist: In the existing investment casting process, the mold shell is usually placed in the baking device without moving. During high-temperature baking, it is easy to cause uneven heating, thereby affecting the quality of the mold shell after high-temperature baking. When taking out, the high-temperature baked mold shell cannot be automatically lifted out of the inside of the device, and needs to be manually taken out by the staff. Since the surface temperature is high, it will increase the risk of scalding for the staff, which is inconvenient.
[0004] Therefore, in view of the above, the existing structure and defects are improved, and a baking device for investment casting is provided to achieve a more practical purpose. INVENTION CONTENTS
