The utility model belongs to the technical field of hollow blow molding machines, and discloses a hollow blow molding machine for urea barrel production, comprising a base. A fixed frame is fixedly installed at the upper end of the base, a screw extruder and a blow molding machine are respectively and fixedly installed at the upper end of the inner cavity of the fixed frame, an injection port is fixedly communicated with the lower end of the screw extruder, and a blowing port is fixedly communicated with the lower end of the blow molding machine. In the utility model, plastic is melted in the screw extruder and extruded quantitatively from the injection port, then placed in a mold. Then, a first cylinder is activated to drive a cutting blade to move, so as to cut the parison. Then, a second cylinder is activated to place the mold under the blowing port and blow air into the mold for cooling, thus completing the molding. Moreover, the directional movement of a push block in the first sliding groove further avoids improper operation caused by manual parison cutting, improves the qualification rate of products, is practical, and is suitable for wide popularization and use.
