The present utility model belongs to an improvement in the structure of a hollow blow molding machine, in particular a die head for an integrated multi-material plastic hollow blow molding machine. It comprises a right-angle die head mounted on an extruder. A slag removal and degassing device is arranged in the inner cavity of a main feed sleeve with a main feed port on the side wall. A flow guide cover and a flow divider are fittingly mounted at the lower part of the main feed sleeve. An outer layer flow sleeve and a surface layer sleeve with a surface material feed port on the side are sequentially mounted from inside to outside on a core rod installed at the end of the conical table of the flow divider, forming a main material flow dividing sandwich channel and a surface material flow dividing sandwich channel. A core die installed at the end of the core rod of the converging channel after the two channels converge cooperates with a conical die installed at the end of the surface layer sleeve to form a conical cylindrical shaping gap. The present utility model enables the hollow blow molding machine to use a large proportion of waste plastic together with new raw materials, can adapt to selected recycled materials with many impurities and relatively high water content, has low production cost, and can produce products with qualified quality and appearance.
