lastic work piece. Its characteristics are short forming cycle, able to form complex shapes, relatively precise dimensions, plastic work pieces without inserts, and high productivity. It is easy to achieve automation production, so it is widely used in the production of plastic work pieces. In recent years, PET blowing bottles have been widely used in beverage packaging due to their light weight, high strength, transparency, non-toxicity, and other advantages, especially in the packaging of carbonated beverages. Therefore, the design of PET resin hollow blowing mold is proposed.
This design scheme first analyzes the geometric structure of PET bottles and the blowing forming process of bottle blanks, as well as the temperature control of the working part of the mold; then, the structure of the hollow blowing mold is proposed, and its working principle is explained. The mold structure is well designed, easy to operate, and can meet the requirements of use.
Keywords: PET resin; bottle blank; blowing mold; cooling water channel.
总结: 吹塑制件设计是一种热塑性塑料制件的主要成形方法,具有成形周期短、可形成复杂形状、尺寸精密、高生产率等特点。近年来,PET吹塑瓶在饮料包装中得到广泛应用,因其质量轻、强度高、透明、无毒等优点。提出了PET树脂中空吹塑模具设计方案,其模具结构设计合理、操作方便,能满足使用要求。通过对吹塑制件设计的研究和实践,可以更好地满足市场需求,提高生产效率,推动塑料制品行业的发展。
