雪碧瓶盖注塑模设计.pdf

摘 要 塑料工业是世界上发展最快的工业之一。在日常生活中几乎每天都使用塑料 制品，这些产品的大部分可由注塑成型的方法生产。众所周知，注塑成型工艺是 制作各种形状的产品和以低成本制作复杂形状产品的制造工艺。本次的毕业设计 的主要内容是雪碧瓶盖的注塑模具设计。从塑料材料的性能分析，根据塑件的基 本形状和尺寸入手，合理选择注射的成型方法。通过对塑件工艺性的分析和对模 具生产条件及制造水平的掌握，制订出成形工艺卡。在制定出成形工艺卡以后 开始进行模具的结构设计。其中模具的结构设计过程包括：型腔的数目和位置的 确定，模具的总体结构形式设计，动模及定模成形零件尺寸的确定，浇注系统形 式及尺寸的确定，脱模方式的确定，调温及排气系统的确定，模架的选择待以上 各步骤完成以后，便开始绘制模具的结构草图，根据具体尺寸校核注塑模具及注 塑机的有关尺寸，并对工艺参数进行核定和计算。之后进行初步的审查对所存在 的问题进行确定和修正，然后绘制模具总装配图，按装配图绘制成型零件及所有 需要加工的零件工作图，同时考虑零件的加工工艺。 关键字：雪碧瓶盖；注塑模具；注射机 Abstract Plastic industry is one of the worlds fastest-growing industrial .In everyday life almost everyday use plastic products, most of these products by injection molding method production. As is known to all, injection molding process is making all sorts of shapes of product and low-cost production complex shape product manufacturing process.The graduation design of the main content is XueBi lid injection mold design. From plastic material performance analysis, according to the basic plastic parts,shape and size of the rational selection of injection molding method. Through the analysis of the technology of plastic parts for mold production conditions and with manufacture level of mastery and work out forming process card. In setting out after forming process card to begin die structure design.One die structure design process includes: cavity number and positioning,die structure form design, dynamic model and decide the determination of forming parts size mold, gating system forms and sizes, stripping the sure way to determine, tempering and exhaust system identified, formwork choice to stay above the steps are done, started drawing die structure sketches, according to the concrete size checking injection molding tool and injection molding machine,and the relevant dimensions of verification and calculation process parameters.
