Abstract
With the development of the plastic industry, the mould plays a more and more important role in modern industry to mould plastics. The mold is more and more high in manufacturing industry status, the mold technical level has become the important symbol to weigh the level of a national manufacturing industry horizontal. This article mainly introduced the injection mold’s designing’s method and process. This paper mainly introduces the method and the process of the injecting mold designing, and analyses the influence of mould shaping structure to the quality of moulds. Next, the whole design process of injection mould is introduced, that is, analysis plastic part, choose injection machine with some of its parameters being checked so as to satisfy design demands, then the injection mould overall design is introduced, such as the forming parts and components design forming plastic part’s geometry and dimension, the pouring systems design transporting melt plastics, the overflow and bleed system design discharging air which affects plastic part’s precision, the temperature adjusted system design only designing the cooling system here, demould mechanism design isolating and retrieving already molding part, and mould-frame design.
There are detailed computations process and rich illustrations in this paper, which make the reader understand the design easily.
