Claims

[Scope of Claim for Utility Model Registration] The lower mold has a semi-cylindrical recess on the upper surface and a larger hexagonal prism-shaped bulging recess that is divided into two parts in the middle thereof, and the upper mold is the lower mold. A semi-cylindrical recess symmetrical to that formed in the lower mold and a hexagonal prism-shaped bulging recess divided into two are formed on the mating surface of the lower mold, and the upper mold is formed on the upper surface of the bulging recess. A cylindrical opening at both ends is provided with a ventilation hole and is formed by overlapping the upper and lower molds, and a presser member with a through hole on at least one side leaves a slight gap between the cylindrical opening and the cylindrical opening. Each presser member is provided with a pressing means such as a hydraulic cylinder that moves the presser member along the cylindrical openings at both ends of the heavy metal mold, and the presser member is fitted in the through hole portion. A liquid feeding pump is connected through the stop valve, and piping from a pressure booster that gradually increases liquid pressure in conjunction with the operation of the pressing means is connected between the through hole and the check valve. A turnbuckle body manufacturing device characterized by:
