[0002] The existing pouring material nozzle needs to be used when pouring the pouring material, and the existing pouring material nozzle is mostly a circular table-shaped funnel-shaped object. When the pouring material nozzle is used, the material falls into the mold through gravity, and part of the material is easily adhered to the inner wall of the pouring material nozzle, which not only wastes raw materials but also is difficult to clean.
[0003] The root cause of the material leakage problem in the connection area of the material conveying pipe and the feed pipe lies in the structural design and material selection of the area. Since the high temperature pouring material needs to withstand high temperature and pressure during the mixing process, the sealing performance of the connection area becomes critical. However, some high temperature resistant pouring material mixed pouring nozzles on the market have not fully considered this point in design, which leads to the easy occurrence of sealing failure in the connection area, resulting in material leakage. This not only wastes materials but also may pollute the production environment and even affect product quality.
[0004] The problem of not easy to disassemble and clean the pouring nozzle is also a big challenge in the design of the current high temperature resistant pouring material mixed pouring nozzle. In a high temperature environment, the pouring material is easily coked or solidified inside the pouring nozzle, causing the pouring nozzle to be blocked. Since the pouring nozzle structure is complex and difficult to disassemble, the cleaning work becomes very tedious, which not only increases the labor intensity of workers but also may affect the quality of the next production due to incomplete cleaning.
