description The utility model discloses a firework powder column compression mould, which comprises an upper substrate, an upper compression column, a powder filling plate provided with a powder filling hole, a lower compression column, a lower substrate and a mould core, wherein the mould core with an upward head is arranged on the top of the lower compression column. By means of the technical scheme, distribution of powder in a lower mould cavity is adjusted when the powder is filled, a powder layer positioned at the head of the mould core is thinner while a powder layer positioned at the tail of the mould core is thicker, each portion of powder bears approximately same force when the compression columns are compressed downwards, so that a formed powder column is even in density of each portion.
