Test mold for detecting water penetration resistance of centrifugal concrete

The invention discloses a test mold for centrifugal concrete water penetration resistance detection, and belongs to the technical field of centrifugal forming concrete molds. The test mold comprises a test mold main body and a test mold inner cavity, the test mold main body is composed of a circular truncated cone defined by circular truncated cone side plates and a bottom plate connected to the lower end of the test mold main body, and the test mold inner cavity is an internal closed circular truncated cone inner cavity formed by connecting the circular truncated cone, the bottom plate and a top plate; the upper end face of the circular truncated cone is a wide opening, the lower end face of the circular truncated cone is a narrow opening, the bottom plate is connected to the narrow opening in a seamless mode, the lower end of the circular truncated cone and the bottom plate are connected to an arc-shaped base in a matched mode, and a fixing spring is arranged on the arc-shaped base located on the periphery
