(Note, because the cooling water is from the inside, the design should let the cooling ring inner diameter and close to the mold wall; if the cooling water is from the outside, the design should let the cooling ring outer diameter and close to the mold wall, this point must not be reversed, otherwise it will cause oil leakage)
