Problems solved by technology
However, there has been a problem that the casting process should be stopped in order to cool the inside of the mold, and this method of cooling the surface of the mold has low cooling efficiency
As mentioned above, if the cooling water fills the outside, there is already a problem that the cooling water is heated so that the cooling efficiency of the mold is reduced and the cooling water flowing through the cooling water inflow pipe directly flows out through the cooling water outflow pipe
However, even in this case, the problem of isolating the cooling water and congesting the cooling water at the changing portion formed at the pipe has arisen

Abstract
A water cooling apparatus for cooling centrifugal casting equipment that includes an upper mold and a lower mold rotating together includes a rotating shaft in which a first cooling passage is formed and to which a nozzle is provided at an end portion of the rotating shaft, and a collecting portion which surrounds a side surface of the lower mold and is installed apart from the lower mold. The lower mold is connected to the rotating shaft and includes a chamber separated from a mold space formed between the upper and lower molds in order to store cooling water injected to the nozzle. The lower mold includes at least one second cooling passage extended from the chamber toward an outer circumference surface direction, and the collecting portion receives the cooling water discharged through the second cooling passage.
Description
technical field [0001] The present disclosure relates to a water cooling device for centrifugal casting equipment. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Centrifugal casting refers to a method of forming a casting by using centrifugal force generated when a mold is rotated at high speed in the process of injecting and melting metal and then allowing it to solidify. To cast via this centrifugal casting method, molten metal needs to be quickly and uniformly injected into the mold so that the molten metal can solidify from the surface in contact with the mold toward the inside of the molten metal, whereby a high-quality cast product free from internal defects can be obtained. For this reason, the rotational speed of the mold, the injection temperature and injection speed of the molten metal should be maintained uniformly. Furthermore, if the...
