An automatic demoulding injection mold for an internal thread cover comprises a movable mold component and a fixed mold component. The stationary mold assembly includes a stationary mold plate 1 and a submarine gate 19. The movable mould component is sequentially provided with a movable mould plate 2, a rotary core 8, a bearing plate 3, a bottom plate 4, a mould foot 20 and a lower compound plate 5 from top to bottom; the movable mould plate 2, the bearing plate 3 and the bottom plate 4 are fixedly connected through a plurality of screws. The bottom of the fixed die plate 1 is provided with an upper die cavity, the top of the movable die plate 2 is provided with a lower die cavity, and the upper die cavity corresponds to the lower die cavity in position and jointly forms a die cavity of the internal thread cover.
