The invention discloses a gravity metal casting mold preparing a magnesium alloy cast ingot specimen. The mold comprises a first mold and a second mold. A first cavity is formed in the first mold, a second cavity which is matched with the first cavity to form an integral pouring cavity is formed in the second mold, a pouring table A is arranged in the middle position in the first cavity, a pouring groove A is formed in the pouring table A, a pouring table B matched with the pouring table A is arranged in the second cavity, a pouring groove B which is matched with the pouring groove A to form a pouring channel is formed in the pouring table B, a groove C is formed in the pouring groove A, and a groove D is formed in the pouring groove B. According to the mold disclosed by the invention, a liquid magnesium alloy can be injected into two ends of the cavity from the middle position of the mold at the same time, so that the time required by conduction is relatively short; in the whole pouring process, the liquid m
