要本設(shè)計(jì)題目為瓶蓋注塑模設(shè)計(jì)，體現(xiàn)了內(nèi)螺紋塑料零件的設(shè)計(jì)要求、內(nèi)容及方向，有一定的設(shè)計(jì)意義。通過(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)者注塑模設(shè)計(jì)的基礎(chǔ)知識(shí)，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)。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(jì)參數(shù)、設(shè)計(jì)要點(diǎn)及推出裝置的選取。本塑件內(nèi)螺紋與開(kāi)模方向垂直，所以在脫模時(shí)必須考慮設(shè)計(jì)一個(gè)能在開(kāi)模時(shí)隨著開(kāi)模過(guò)程的進(jìn)行使塑件和型腔脫離。本副模具的設(shè)計(jì)中，采用了斜滑塊側(cè)抽芯機(jī)構(gòu),在開(kāi)模時(shí),動(dòng)模后退,斜滑塊沿主型芯斜面滑動(dòng),在滑動(dòng)的過(guò)程中,在推桿的作用下,塑件脫離型芯,直到塑件脫出型腔。這種機(jī)構(gòu)脫?？煽?，設(shè)計(jì)方便且在模具中占用空間較小，非常適合在本副模具中使用。關(guān)鍵詞：注塑模 澆口 內(nèi)螺紋 斜滑塊 AbstractThe requirement ，content and direction of the design of the internal screw thread 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 composition and the performance of the part are analyzed to choose the type of the gat .Secondly, the volume of the part is estimated to choose the injection molding machine and to determine the mould quantity conveniently. Lastly the character of the part is analyzed to determine the mould design parameter and design point and choose the ejection assembly. The part’s internal screw thread is perpendicular to the open direction of the mould. So we must device a segregate unit that makes the part and the mould to segregate simultaneously when the mould is opened. In this mould design, side loose core gear is used with taper slide .When the mould open ,the motor module back away ,the taper slide slumps along the main core, at the same time, the part is pushed off by ejector pins from the mould upward. The core makes ejection credibly and the design conveniently and occupies little room. So, it is adapted to be used on this mould extraordinarily.Keywords: Injection mould , gate , internal screw thread, taper slide
