A continuous production mold for automobile corner plate parts

Abstract

The invention relates to a continuous production mold for automobile angle plate parts. The continuous production mold comprises a lower mold and an upper mold, wherein the lower mold comprises a lower mold seat and a lower mold core fixedly arranged on the lower mold seat; the upper mold comprises an upper mold seat, an upper mold core which is arranged on the lower surface of the upper mold seat, and a material pressing plate which is arranged at the middle lower part of the upper mold core and is connected with the upper mold core; a punching male mold, a trimming male mold, a flanging male mold and a reshaping male mold are sequentially arranged on the lower mold core; a punching female mold, a trimming female mold, a flanging female mold and a reshaping female mold are sequentially arranged on the upper mold core; the flanging male mold comprises two flanging supporting surfaces which are perpendicular to each other; included angles between the two flanging supporting surfaces and the horizontal plane are complementary angles; the included angle between one of the flanging supporting surfaces and the horizontal plane is 45-85 degrees; the setting angle of the flanging female mold is matched with that of the flanging male mold. Compared with the prior art, the continuous production mold has the advantages of simple structure, long service life, convenience in maintenance, high punching efficiency, low punching cost and the like; the flanging angle is easy to control.

Description

technical field [0001] The invention relates to a production mold for automobile parts, in particular to a continuous production mold for automobile corner plate parts. Background technique [0002] Gussets are an important part of the car body. In many cases, traditional molds can only punch one half-process part at a time during the production process, which increases the cost of stamping. There are potential safety hazards in the process of personnel operation, and the quality problems of stamping parts caused by human misoperation. [0003] Chinese patent CN 203972619U discloses a mold for the integral molding of automobile reinforcement panels, including a lower mold and an upper mold. The lower mold includes a lower mold base, a lower mold core and an ejector, and the lower mold core and the ejector are arranged on the lower mold base; The upper mold includes an upper mold base, an upper mold core, an upper mold insert, an upper mold presser and an upper ejector pin. ...

Problems solved by technology

[0004] However, in the above-mentioned mold, the flanging shaping process is the same as the traditional flanging process, which is to turn 90° downwards in the vertical direction. At 90°, because the knives are parallel to each other, there is no force in the horizontal direction, and the flanging is not in place.
