[0036] According to the above structure provided in the present embodiment, it can be known that the present embodiment provides a casting lost mold for a valve actuator box, and the material thereof is prepared by a paraffin material commonly used in the art. Compared with the prior art, in the valve actuator box casting mold in the present embodiment, since the center axes of the flange portion 102 and the rim portion 103 connected to the box body portion 101 are located on different planes, the first flow channel portion 104 can facilitate the molten steel to quickly reach the flange portions 102 at both ends so that the flange portions 102 can be more fully formed, and the second flow channel portion 105 can facilitate the molten steel to quickly reach the rim portion 103 so that the rim portion 103 can be more fully formed.
