A water cooling apparatus for cooling centrifugal casting equipment including an upper mold and a lower mold rotating together, said water cooling apparatus comprising:

• a rotating shaft in which a first cooling passage is formed, and a nozzle provided at an end portion of the rotating shaft,
• the lower mold being connected to the rotating shaft, and including a chamber configured to store a cooling water injected from the nozzle and at least one second cooling passage extended from the chamber toward an outer circumference surface direction of the lower mold, the chamber separated from a mold space formed between the upper and lower molds;
• and
• a collecting portion spaced apart from and surrounding a side surface of the lower mold, and the collection portion configured to collect the cooling water discharged toward the side surface of the lower mold through the second cooling passage.
