摘 要
本設(shè)計(jì)題目為汽車活塞托架注塑模設(shè)計(jì)，體現(xiàn)了深薄壁類塑料零件的設(shè)計(jì)要求、內(nèi)容及方向，有一定的設(shè)計(jì)意義。通過對該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者注塑模設(shè)計(jì)的基礎(chǔ)知識，為設(shè)計(jì)更復(fù)雜的注塑模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。
通過觀察分析可知，該產(chǎn)品結(jié)構(gòu)簡單，用于該產(chǎn)品生產(chǎn)的注塑模具結(jié)構(gòu)亦不復(fù)雜，直接采用頂桿頂出本設(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，首先分析了塑件的成分及性能要求，為選取澆口的類型做好了準(zhǔn)備；然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。

Abstract
This design topic notes a mold design for the car piston bracket, body now deeply thin wall plastics design request, contents and direction of the spare parts, there is certain design meaning.Pass the design to the spare parts' molding tool, strengthenned a design to note the Su mold foundation knowledge of design further, for design to more complicatedly note a molding tool to have done cushion and absorb deeper experience.
Pass the observation analysis can know, the product's structure simple, used for that product to produce of note a Su molding tool structure as well not complicated, direct doption crest pole crest originally designs usage plastics to model the foundation knowledge of craft and molding tool design, composition and function which analyzed a Su piece first request, sprinkle an oscular type to have done preparation for the selection;Then analyzed the characteristic of Su piece, make sure the design parameter, design important point of molding tool and release the selection of device.
