骨 輪 注 塑 模 設(shè) 計(jì) 摘 要 本設(shè)計(jì)題目為骨輪注塑模設(shè)計(jì) 體現(xiàn)了側(cè)抽芯類塑料零件的設(shè)計(jì)要求 內(nèi)容及方 向 有一定的設(shè)計(jì)意義 通過對(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 在模具設(shè)計(jì)中采用插入式哈夫塊的側(cè)向抽芯機(jī)構(gòu)成型環(huán)形外側(cè)凹 使模具結(jié)構(gòu)簡(jiǎn)單 加工方便本塑件哈夫塊運(yùn)動(dòng)與開模方向不一致 所以在脫模時(shí)必須考慮設(shè)計(jì)一個(gè)能在 開模時(shí)隨著開模過程的進(jìn)行使哈夫塊分離的裝置 本副模具的設(shè)計(jì)中 在定模部分設(shè) 計(jì)安裝了斜導(dǎo)柱 在開模時(shí)推件板頂出塑件同時(shí)驅(qū)動(dòng)滑塊側(cè)分型 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 工藝分析 塑件 推板 哈夫塊 骨 輪 注 塑 模 設(shè) 計(jì) Abstract The requirement content and direction of the design of the skeleton lastics combinations plastic parts are embodied on this injection mould design of the plastic parts of lateral moving core pulling 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 This molde design need other side to open on the open molde According to the structure and technology characters of the plastic part with outside annular concave the bayonet Half is used in the injection mould At the open molde the ejector plate ejects the plistic parts at the same time it will made the moving cores move the other side until the plistic parts ejector the cavity this molde ejector is very good because this molde use short area and design easy we often use it Keywords Injection mould process analysis Models Ejector plate the bayonet Half
