Abstract

The invention relates to the technical field of forging, in particular to a die design method for improving local fluidity of a large component. Comprising the following steps that S1, an upper die and a lower die are arranged according to a forge piece; the upper mold is provided with a first cavity, the first cavity is internally provided with a first area for forming a high bag and a second area for forming a lug, and the lower mold is provided with a second cavity; s2, the maximum distance H1 from the first area to the lower surface of the upper mold and the maximum distance H2 from the second area to the lower surface of the upper mold are measured; S3, first bosses are arranged on the two sides of the first area, and second bosses are arranged on the outer side of the second cavity; third bosses are arranged on the two sides of the second area, and a fourth boss is arranged on the outer side of the second cavity. A first bridge part is formed between the first boss and the second boss, and a second bridge part is formed between the third boss and the fourth boss; according to the height requirements of different areas of the forge piece, the bridge parts with different heights are arranged, and the filling effect in the cavity is improved.
