Description

Automobile bumper mould

Technical Field

The automobile bumper is a safety device for absorbing and relieving external impact force and protecting the front part and the rear part of an automobile body. The front and rear bumpers of the automobile are stamped into channel steel by steel plates and riveted or welded with the frame longitudinal beam for many years, and a large gap is reserved between the channel steel and the automobile body, so that the front and rear bumpers of the automobile are quite unattractive. The front and rear bumpers of the sedan car of today are required to be harmonious and unified with the shape of the car body and to be light in weight in itself, besides maintaining the original protection function. The front and rear bumpers of a car are all made of plastic and are called plastic bumpers.

In order to ensure the smooth demoulding of the product, the whole automobile bumper product can be removed from the mould only by carrying out secondary ejection, but if the secondary ejection is adopted, the demoulding cost is greatly increased, and the demoulding efficiency is reduced. If the automobile bumper mold is forcibly taken, the structure of the automobile bumper mold is deformed and damaged, so that the quality of a front bumper is affected.
