防護(hù)罩塑料成型工藝與模具設(shè)計(jì)
摘要： 本設(shè)計(jì)題目為防護(hù)罩塑料成型工藝與模具設(shè)計(jì)，來(lái)源于書(shū)籍，體現(xiàn)了典型塑料模的設(shè)計(jì)要求、內(nèi)容及方向，有一定的設(shè)計(jì)意義。通過(guò)對(duì)該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者塑料模設(shè)計(jì)的基礎(chǔ)知識(shí)，為設(shè)計(jì)更復(fù)雜的塑料模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。
本設(shè)計(jì)運(yùn)用塑料成型工藝及模具設(shè)計(jì)的基礎(chǔ)知識(shí)，首先分析了塑件的成分及性能要求，為選取澆口的類(lèi)型做好了準(zhǔn)備；然后估算了塑件的體積，便于選取注塑機(jī)及確定型腔數(shù)量；其次看是否需要側(cè)抽，如需要，選擇合適的側(cè)抽機(jī)構(gòu)，確定其工作原理；最后分析了塑件的特征，確定模具的設(shè)計(jì)參數(shù)、設(shè)計(jì)要點(diǎn)及推出裝置的選取。

Plastic molding process and die design of protective cover
Abstract: This design topic is cover plastic molding process and mold design protection, from books, reflects the typical plastic mould design requirements, content and direction, the design of a certain significance. Through the design of the die parts, further strengthen the designers of basic knowledge of plastic mold design, paving the way and draw a more profound experience for the plastic mold design more complex.
This design using the basic knowledge of plastic molding process and mold design, first analyzes the composition and performance of the plastic parts, ready to select the type of gate; plastic parts and estimated the volume, to select the injection molding machine and determine the number of cavities; secondly whether need to side, if necessary, select the appropriate the side core pulling mechanism, its working principle is determined; finally analyses the characteristics of plastic parts, determination of design parameters, die design and the introduction of the selected devices.
Keywords: gate side pumping
