Abstract

The invention relates to a divergent die structure of an extrusion die and a preparation method thereof, the divergent die structure comprises an upper die, a lower die and a die cushion which are mutually matched and mounted together, the upper die, the lower die and the die cushion are positioned by pins and are connected through screws, and the upper die comprises a divergent bridge, divergent holes divided by the divergent bridge and a die core; a die hole is formed in the center of the lower die, a flow speed control cavity surrounding the die hole is formed in the feeding face of the lower die, a welding chamber is arranged on the periphery of the flow speed control cavity, and a plurality of strength pin holes are formed in the discharging face of the lower die. The vertical distance between the edge of the strength pin hole and the edge of the die hole is larger than 5 mm. A center through hole which is geometrically similar to the shape of the die hole is formed in the center of the die cushion, and a strength pin matched with the strength pin hole is arranged on the feeding face of the die cushion. According to the divergent mold structure and the rapid preparation method for the divergent mold, the preparation period of an original mold can be shortened by 71%, meanwhile, the consumable cost of the mold can be saved, and the production cost is reduced while the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of aluminum profile extrusion die manufacturing, in particular to an extrusion die split die structure and a preparation method thereof. Background technique [0002] In the preparation process of aluminum profiles, extrusion is a common means of forming aluminum profiles, and molds are essential tooling in the extrusion process. Molds need to be designed and manufactured according to the cross-sectional structure of profile products. Existing aluminum profiles Extrusion dies can be basically divided into two categories: planar dies and splitter dies. [0003] Among them, the splitter mold is mainly used in the forming of some aluminum profiles with relatively complex structures. The splitter mold includes an upper mold, a lower mold and a die pad, while the conventional splitter mold structure often needs to include a splitter hole, a mold core, and an outlet when designing. Material port and working belt and other ...
