The utility model relates to the technical field of steel-plastic composite barrels, in particular to a fixing device for plastic liner inserts. The overall structure comprises a first fixing device and a second fixing device installed side by side on a blow molding machine. Both fixing devices comprise a blow needle bottom plate connected to an air nozzle support of the blow molding machine. A blow needle base is connected to the blow needle bottom plate for connecting a blow head to the blow needle bottom plate. A piston is arranged in central holes of the blow head and the blow needle base. An ejection cone is arranged at the top of the blow head on the fixing device. The overall structure eliminates the screwing-in and screwing-out actions of insert bosses, reducing labor intensity. Subsequent placement of plastic inserts by a manipulator enables automated production of plastic liners, improving production efficiency and automation of plastic liners for hollow blow-molded steel-plastic composite barrels.
