style="text-indent:25px">全過程實(shí)施并行工程：全過程實(shí)施并行工程是縮短模具開發(fā)周期比較有效的途徑之一。所謂并行工程就是模具開發(fā)過程中的各工序、各環(huán)節(jié)都要同步、并行、交叉進(jìn)行，盡量避免串行。在汽車車身的開發(fā)過程中，是研發(fā)部門的產(chǎn)品開發(fā)后期和模具開發(fā)前期的并行工程，即產(chǎn)品研發(fā)部門在車身數(shù)模凍結(jié)之前，利用設(shè)計(jì)版車身數(shù)模和模具廠技術(shù)部門進(jìn)行設(shè)計(jì)評(píng)審、工藝會(huì)簽，使產(chǎn)品開發(fā)得到完善。與此同時(shí)，模具廠利用設(shè)計(jì)版數(shù)模進(jìn)行模具開發(fā)方案的策劃、制定開發(fā)預(yù)算、計(jì)劃和沖壓工藝方案’、開展DL圖設(shè)計(jì)、進(jìn)行拉延模初步設(shè)計(jì)和鑄造實(shí)型加工。該階段的并行工程可將模具的開發(fā)時(shí)間縮短1～2個(gè)月；是模具開發(fā)過程中的技術(shù)準(zhǔn)備、生產(chǎn)準(zhǔn)備、模具加工和調(diào)試各工序之間的并行工程，即生產(chǎn)準(zhǔn)備、加工工藝及數(shù)控程序設(shè)計(jì)并行。止口是模具外觀的重要組成，止口的設(shè)計(jì)以受力均衡為原則，止口又叫虎口，是保證模具定位的。平湖汽車模具市場(chǎng)</p><p
