摘 要
本設(shè)計題目為罩盒注塑模設(shè)計，體現(xiàn)了盒類塑料零件的設(shè)計要求、內(nèi)容及方向，有一定的設(shè)計意義。通過對該零件模具的設(shè)計，進(jìn)一步加強(qiáng)了設(shè)計者注塑模設(shè)計的基礎(chǔ)知識，為設(shè)計更復(fù)雜的注塑模具做好了鋪墊和吸取了更深刻的經(jīng)驗。本設(shè)計運用塑料成型工藝及模具設(shè)計的基礎(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；然后估算了塑件的體積，便于選取注塑機(jī)及確定型腔數(shù)量；最后分析了塑件的特征，確定模具的設(shè)計參數(shù)、設(shè)計要點及推出裝置的選取。

Abstract
The requirement ，content and direction of the design of the deep thin wall plastic parts are embodied on this injection mould design of the plastic parts of long pipe box. The designer’s foundation knowledge of the injection mould design is reinforced and is able to design more complex injection mould through the design. Through the foundation knowledge, firstly, the composion and the perfourmance of thr part is analyzed to choose the type of the gat advantagely. Secondly, the volume of the part is estimated to choose the injection molding machine and to detemine the mould quantity conveniencely. Lastly the character of the part is analyzed to determine the mould design parameter and design point and choose the ejection assembly.
Keywords: Injection mould , dfaf, ejecting block
