The invention provides a die. The die comprises a die plate equipped with a guide column hole, a guide column which is equipped with a mounting section in the guide column hole and a guide section at the outside of the guide column hole, and a fixing part which is detachably mounted into the guide column hole in the die plate to limit the axial moving of the guide column. According to the die, the guide column hole for storing the guide column is formed, the fixing part for limiting the axial moving of the guide column is arranged, and therefore, the guide column can be directly matched with the guide column hole, and as a result, the fixing seat structure in the prior art can be saved; the die plate can be small in size, so that the purpose of reducing the size of the die plate on the premise that the die strength is met is reached.
