1.模具結(jié)構(gòu)設(shè)計(jì)1.1設(shè)計(jì)任務(wù)第1～2題塑料盒，大批量生產(chǎn)，精度：MT5。(要求采用標(biāo)準(zhǔn)模架設(shè)計(jì)）（班級名單序號1～2號同學(xué)按照名單排序分別做各對應(yīng)題目）1號同學(xué)選01圖號，按照側(cè)澆口結(jié)構(gòu)設(shè)計(jì)2號同學(xué)選02圖號，按照其它澆口形式設(shè)計(jì)因班級名單序號為1，故選01號圖1.2模具結(jié)構(gòu)設(shè)計(jì)1.2.1分型面位置的確定通過對塑件結(jié)構(gòu)形式的分析，分型面應(yīng)選在端蓋截面積最大且利于開模取出塑件的底平面，其位置如圖2-1所示。圖1-1分型面的選擇1.2.2型腔數(shù)量和排位方式的確定（1）型腔數(shù)量的確定由于該塑件的精度要求不高，塑件尺寸較小，且為大批量生產(chǎn)，分型面的選擇可采用一模多腔的結(jié)構(gòu)形式。同時(shí)，考慮到塑件尺寸、模具結(jié)構(gòu)尺寸的關(guān)系，以及制造費(fèi)用和各種成本費(fèi)用等因素，初步定為一模兩腔結(jié)構(gòu)形式（2）型腔排列形式的確定由于該模具選擇的是一模兩腔，故流道采用對稱排列，使型腔進(jìn)料平衡（3）模具結(jié)構(gòu)形式的初步確定由以上分析可知，本模具設(shè)計(jì)為一模兩腔，對稱H形直線排列，根據(jù)塑件結(jié)構(gòu)形狀，推出機(jī)構(gòu)初選推件板推出或推桿推出方式。澆注系統(tǒng)設(shè)計(jì)時(shí)，采用對稱平衡式流道，側(cè)澆口，且開設(shè)在分型面上。因此，定模部分不需要單獨(dú)開設(shè)分型面取出凝料，動(dòng)模部分需要添加型芯固定板、支承板或推件板。由以上綜合分析可確定采力安全用大水口（或帶推件板）的單分型面注射模模具設(shè)計(jì)的具體過程與各參數(shù)的確定已在設(shè)計(jì)說明書中完成，故不在贅述，模具的結(jié)構(gòu)如下圖1-2模具的結(jié)構(gòu)
