However, there is a problem of oil leakage, and the structure of the two parts of the injection cylinder locked by the screw has the risk of oil leakage. When the charging barrel is injected, the inside of the charging barrel bears quite large injection pressure, the screw is elastically deformed under the action of the injection pressure, and the elastic deformation is not large, but the O-shaped ring for sealing can be disabled, so that oil leakage is caused. Oil leakage is a serious equipment problem, can directly lead to scrapping of products, and is troublesome to maintain.
