1、摘要摘要吹塑成型是熱塑性塑料制件的一種主要成形方法。吹塑成形可成形各種形狀的塑料制件。它的特點(diǎn)是成形周期短，能一次成形外形復(fù)雜，尺寸較為精密，不帶嵌件的塑料制件，且生產(chǎn)率比較高，易于實(shí)現(xiàn)自動化生產(chǎn)，所以廣泛用于塑料制件的生產(chǎn)。近年來，PET吹塑瓶以其質(zhì)量輕、強(qiáng)度高、透明、無毒等優(yōu)點(diǎn)被大量用于飲料包裝，特別是碳酸性飲料的包裝，于是提出了PET樹脂中空吹塑模具設(shè)計。該設(shè)計方案首先分析了PET瓶的幾何結(jié)構(gòu)和瓶坯的吹塑成型工藝，模具工作部分的溫度控制等；然后提出了中空吹塑模具的結(jié)構(gòu)，并闡述其工作原理。該模具結(jié)構(gòu)設(shè)計合理，操作方便，能滿足使用要求。關(guān)鍵詞：PET樹脂；
