First, though the observations of the frig , the paper advance mechanism was designed. Draw threedimensional view of the structure of products. Anoalyzed the technological characteristics, the selection of size tolerance and of the paper advance mechanism. Second, 常熟理工學(xué)院畢業(yè)設(shè)計(jì) (論文） III analysised and designed the structure of the mold. include the determination of the number of cavity, the mainstream, and shunt the design, select the type of surface, the gate design, cavity of the core structure of the set, and so on. This article focuses on the work of die size and the calculation of fixed form, the subsurface structure, temperatureconditioning systems, Stripping out the top institutions, oblique lateral slider type and core pulling bodies, institutions and other major ponents reset the design process. Finally, checked the injection of injection machine, the clamping force, opentrip process parameters. Introduced the die installation and test mode. The main structure of the mold is used three plate die, the injection point gate, ramp slider, core pulling bodies from the top of putting plastic parts, a reductionreduction. The mold is used in automatic mode of productions。 the product of the efficiency of the production has a very important role.
