The utility model belongs to the field of plastic barrel production, and discloses a hollow blow molding machine for plastic barrels, comprising a main device for extruding parisons and moving mold clamping. A blowing device for lifting and extending into the mold cavity for blow molding is arranged at the bottom of the main device, and a supporting device for lifting and supporting the parison and double-station insertion into the parison to restrict swinging is arranged on one side of the blowing device. The supporting device comprises a lifting frame on which two lifting screws are symmetrically mounted front and rear, and synchronous wheels are arranged at the bottoms of the lifting screws. The hollow blow molding machine for plastic barrels reduces deformation caused by parison sagging by lifting and supporting the parison, improving blow molding quality. Insertion into the parison to restrict swinging further ensures molding quality. Double-station supporting and restriction enable simultaneous processing of two plastic barrels, increasing blow molding speed.
