Automobile rear floor crossbeam part die

Abstract

The invention relates to an automobile rear floor crossbeam part die. The die comprises a lower die and an upper die. The lower die comprises a lower die base (1), a lower die core and an ejection system, wherein the lower die core and an ejector are arranged on the lower die base. The lower die core is sequentially provided with a trimming piercing male die (2), a flanging sizing male die (4) and a side piercing male die (7). The upper die comprises an upper die base (9), an upper die core, an upper die insert, an upper die pad and an upper ejector pin (6), wherein the upper die core is arranged below the upper die base, the upper die core is sequentially provided with a trimming piercing female die (3), a flanging sizing female die (5) and a side piercing female die (8), and the upper ejector pin (6) is arranged above the upper die base (9). Compared with the prior art, the die disclosed by the invention has the advantages of low production cost, safety, reliability and the like.

Description

technical field [0001] The invention relates to a mold for producing automobile parts, in particular to a mold for automobile rear floor beam parts. Background technique [0002] The rear floor beam is a part welded on the rear floor of the car. Its function is to strengthen the strength and rigidity of the rear floor of the car and improve the torsion and mode of the car body. At present, the mold of this kind of parts is divided into two processes of punching and edge trimming, which requires two punches during production, requires a large number of operators, high manufacturing cost, long manufacturing cycle, and low production efficiency. The existing upper mold presser uses a spring or nitrogen spring as a power source, and the spring or nitrogen spring will be damaged normally and requires regular replacement, and the maintenance and replacement costs during the production process will be greatly increased. Contents of the invention [0003] The purpose of the prese...
