Abstract

The invention discloses an automobile radiator hood flanging die. The automobile radiator hood flanging die is characterized in that a slider is in an L-shaped structure and can slide along a base towards the central line of the automobile radiator hood flanging die, and the upper portion of the outside of the slider is provided with an inclined surface; a terrace die is fixed at the bent part ofthe slider; the end portion of the slider is provided with an inclined surface; the inside of an inner insert is provided with an inclined surface, and the outside of the inner insert is provided witha curved surface matched with the inner wall of a radiator hood; the lower end of an ejecting block is provided with a first frustum, the upper end of the ejecting block is provided with a second frustum, the first frustum is matched with the inclined surface of the end portion of the slider, and the second frustum is matched with the inclined surface inside the inner insert; a flanging gap is formed between the upper end surface of the terrace die and the lower end surface of the inner insert, the ejecting block is arranged inside a gap between the inner insert and the base, and the inclinedsurface of the upper portion of the outside of the slider is matched with a wedge. The automobile radiator hood flanging die has the advantages of being high in efficiency, good in product quality and capable of facilitating material discharging.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, and in particular relates to a flanging die for the top of an automobile water tank cover. Background technique [0002] The degree of automation of automobile molds is getting higher and higher, and many automobile OEMs have adopted multi-station molds and automated production lines for production. The top of the automobile radiator cover is a disc-shaped structure, and the lower part needs to be flanged inward during processing. Because of its disc-shaped structure, it is difficult to press the inside and outside of the flanging process, and the unloading process is relatively difficult. trouble. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide an automobile water tank cover top flanging mold. [0004] A flanging mold for the roof of an automobile water tank cover, comprising: [0005]...
