Manufacturing method of tapered bumper post

Abstract

The invention provides a manufacturing method of a light-weight stable tapered bumper post. The manufacturing method comprises the following steps: (1) manufacturing a left die, a right die and a lower die which can be assembled into a cone-shaped body, wherein the lower die is trapezoidal, and the left die and the right die are semi-tapered; (2) laying lining layers and fiberglass gridding cloth on the left die and the right die, filling with light-weight medium materials, and then performing die assembly on the left die and the right die; (3) laying a lining layer and fiberglass gridding cloth on the lower die, filling with a heavy-weight material, and then integrally assembling the lower die with the left die and the right die. According to the manufacturing method, the tapered bumper post is obtained by die assembly of the left die, the right die and the lower die; the materials of different weights are adopted to enable acquisition of a stable base manufactured by combination of linings and core materials, so that a role of enhancing the stability of the base is played, the center of gravity of the whole tapered bumper post is lowered, and the tapered bumper post can be placed firmly. As the upper tapered body is filled with the light-weight material, an excellent weight reducing effect is taken.

Description

technical field [0001] The invention relates to a method for preparing traffic equipment, in particular to a method for preparing a tapered car bumper. Background technique [0002] At present, the cone-shaped car bumpers on the market are mainly made of plastic shells, and an appropriate amount of gravel is poured into the interior to play the role of overall pressure and stabilize the center of gravity. Adhesive stickers are often used on the outside of the bumper to modify some text or graphics for further improvement. its use function. [0003] Although the existing tapered car bumper mainly made of plastic has good waterproof performance, its fire resistance and weather resistance are poor, and its impact resistance is insufficient, and it is easy to be damaged by automobile rolling. It is easy to fall off and damage when exposed to the sun, and the overall weather resistance and anti-aging performance are poor. Contents of the invention [0004] The invention p...
