The invention discloses a compression buffer spring of an automobile shock absorber and a molding die thereof. The compression buffer spring is an integral injection molded part, and has middle ribs, transition ribs and edge ribs arranged in parallel, and the ribs are integrally connected to each other. There are axially stretchable and arc-shaped elastic thin walls, and the elastic thin walls are provided with through holes through the inside and outside. The forming mold includes an injection mold composed of a front mold, a rear mold and a core pulling assembly, and a forming jig composed of a steel hoop and a press. Applying the compression buffer spring and its forming mold of the present invention, adopting relatively light injection molding to produce the compression buffer spring made of plastic material, breaking through the technical dilemma of relying on metal to manufacture elastic parts in the industry for a long time, and developing a new elastic product , and make the product performance meet the rigidity, temperature and durability requirements of the application. At the same time, the invention provides a better forming mold for the compression buffer spring to ensure the inheritance of product performance.
Description
technical field [0001] The invention relates to a plastic product and its tooling, in particular to a single, high-rigidity, high-temperature and durable non-metallic elastic part and its forming mold used in automobile shock absorbers to realize restoration and buffering. Background technique [0002] With the continuous development of the automobile industry, in addition to the rapid development of energy and power research and development, and the pursuit of higher energy efficiency, the requirements for the comfort of the vehicle are also increasing. In order to slow down the energy during the bumping process of the vehicle, it must involve automobile shock absorption. The structural design of the device. The traditional automobile shock absorber consists of a shell, an oil inlet pipe, a support rod and a compression buffer spring. And the compression buffer spring wherein mostly is metal product, has two technical defectives that are difficult to overcome. One is that...
