摘要吹塑成型是热塑性塑料制件的一种主要成形方法。吹塑成形可成形各种形状的塑料制件。它的特点是成形周期短，能一次成形外形复杂，尺寸较为精密，不带嵌件的塑料制件，且生产率比较高，易于实现自动化生产，所以广泛用于塑料制件的生产。近年来，PET 吹塑瓶以其质量轻、强度高、透明、无毒等优点被大量用于饮料包装，特别是碳酸性饮料的包装，于是提出了 PET 树脂中空吹塑模具设计。该设计方案首先分析了 PET 瓶的几何结构和瓶坯的吹塑成型工艺，模具工作部分的温度控制等；然后提出了中空吹塑模具的结构，并阐述其工作原理。该模具结构设计合理，操作方便，能满足使用要求。 关键词： PET 树脂； 瓶坯； 吹塑模； 冷却水道。 ABSTRACTThe blowing injection formation is the thermoplastic work piece one main formed method. The injection forming may form each kind of shape the plastic work piece. Its characteristics is to take shape period short, can take shape the shape complications once, size nicety, take the plastics system piece of have the piece, and the rate of production is high, being easy to carry out the automation production, so used for the production of the plastics system piece extensively.In recent years, with its quality mould high trength, ransparent, non-toxic advantages ,PET bottles were used to the beverage packaging, especially the carbonate drink . Then PET resin for blow molding mould design. The design scheme is firstly analyzed the geometrical structure of PET bottle of bottle preform and blow molding process. Mould work of temperature control parts etc. Then it puts forward for blow molding mould structure.,and its working principle. The mould structure reasonable design, convenient operation, can satisfy the requirements of operation .Keywords: PET resin; bottle reform; blowing mold; cooling channels.目录摘要...........................................................................................................
