Plastic industry is grows now one of quickest industry classes in the world, but casts the mold is development quick type, therefore, the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance.
With the development of the plastic industry, the mould plays a more and more important role in modern industry to mould plastics. 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.After the structure analysing of the mould,draw and design the appearance.structure with the UG three dimensional entity designing, then carry on drawing of patterns organization, cooling system of mould, core, mould shelf and design to lead organization,etc.. Core-pulling structure is the emphsis and difficulty of the article. We have used the slanting guide pillar side pulls out method , after the analysis which is both economy and effective, and it can solve this question perfectly .
Through this design, may to cast the mold to have a preliminary understanding, notes in the design certain detail question, understands the mold structure and the principle of work; Through to the PROGRAM study, may establish the simple components the components storehouse, thus effective enhancement working efficiency.
Key words: Mold ;Inclined push rod ;Core-pulling structure ;Core models
