A kind of manufacturing method of lightweight rubber shock absorber for automobile

Abstract

The invention discloses a making method of a lightweight rubber shock absorption member for an automobile. The rubber shock absorption member is characterized in that the rubber shock absorption member is composed of a rubber mainspring, a plastic support and a metal insert, and the making method comprises the steps of vulcanization, gluing, drying, assembling, injection molding, cooling and moisture absorption. The method has the advantages of simple technology and low cost, and the lightweight rubber shock absorption member made through the method has a good performance and a long service life.

Description

technical field [0001] The invention relates to the field of automobile parts manufacturing, in particular to a method for manufacturing a lightweight rubber shock absorber for automobiles. Background technique [0002] The current energy shortage and environmental pressure are increasing, and the sustainable development of the automobile industry is facing challenges. As an effective means of energy saving, automobile lightweight technology has become one of the important research topics in the development of the automobile industry. At present, there are three main ways to realize the lightweight of automobiles: one is to optimize the structure of automobile chassis, engine and other parts, and the structural design mainly adopts methods such as front-wheel drive, high rigidity structure and ultra-light suspension structure; the other is to use In terms of materials, the weight of automobiles can be reduced through material substitution. In terms of alternative materials, ...

Problems solved by technology

[0004] At present, the process of making plastic-rubber composite parts is similar to that of traditional metal-rubber parts, but for automotive structural parts, this process has the following defects: According to the traditional process, the plastic bracket and the rubber main spring generally need to be vulcanized simultaneously However, due to the larger bracket and the more complex plastic structural parts compared to the metal structure, the cost of the rubber mold is higher, the edge sealing and pressure retention are more difficult, and the manufacturing process is also more difficult, especially when the plastic bracket and rubber are exposed to high temperature. Vulcanized together in the mold, during the long-term vulcanization process of 5-20 minutes, it is easy to cause degradation or shape change of the plastic, thereby reducing the performance and service life of engineering plastics
