Description

High-temperature-resistant corrosion-resistant glass gob flushing rod Technical Field The utility model belongs to the technical field of glass product production, and particularly relates to a high-temperature-resistant corrosion-resistant glass gob flushing rod. Background In the production process of glass products, a glass gob punching rod is a key component in a forming process, and is directly contacted with high-temperature glass gobs, so that the forming quality and the production efficiency are greatly affected. The traditional punching rod head adopts an integrated fixed connection structure, and the punching rod has certain temperature resistance, but is still easy to crack and wear under long-term high-temperature impact, and the large loss of yield can be caused when the punching rod is replaced every time.
