The invention discloses a centrifugal casting mould for a cylinder sleeve. The centrifugal casting mould comprises a mould housing and a baffle, wherein the interior of the mould housing is an inner chamber; the inner diameter of the inner chamber is reduced sequentially and the inner chamber is step-shaped; the formed shape of the inner chamber is the same as the shape of the finished cylinder sleeve; the baffle is arranged at one end of the mould housing; and an air outlet communicated with the inner chamber is formed in the mould housing. According to the centrifugal casting mould disclosed by the invention, air in the mould can be exhausted smoothly since the air outlet communicated with the inner chamber is formed in the mould housing, so that mould opening of the product is easy and rapid, and the problem that the mould is difficultly opened due to overhigh pressure is avoided.
