46、受的效果。 當(dāng)機(jī)器循環(huán)時(shí),塑料首先注射到A 面。由于瓶胚要留在模芯上,瓶胚在開模不需要象在傳統(tǒng)系統(tǒng)上那么硬。因此,循環(huán)的絕大部分冷卻可以在隨后的機(jī)器循環(huán)期間從閉模轉(zhuǎn)到在模芯上冷卻。然后循環(huán)需要一個(gè)非常短的冷卻期間以允許模具釋壓,注射和保壓也是如此。當(dāng)開模時(shí),這一面轉(zhuǎn)位到壓板的頂部表面,然后塑料在B 面注射。當(dāng)D 面到達(dá)前端時(shí),此時(shí)A 面在壓板的底部位置,頂桿在這里被啟動(dòng),瓶胚被從機(jī)器卸到制件引出傳送器上。注射行程對(duì)循環(huán)時(shí)間沒有影響,因而

49、.5 秒,對(duì)于一個(gè)陰模系統(tǒng)來說是最佳的了。轉(zhuǎn)位48 陰模系統(tǒng)實(shí)現(xiàn)14.2 秒的循環(huán),能取得較好的商業(yè)質(zhì)量結(jié)果。圖2 給出循環(huán)細(xì)分的比較情況。</p><p>　　旋轉(zhuǎn)塔臺(tái)不再需要機(jī)械手。這樣,就減少了由傳統(tǒng)系統(tǒng)上機(jī)械手故障造成的干擾告警和服務(wù)停機(jī)時(shí)間。制件頂出現(xiàn)在不是機(jī)械循環(huán)時(shí)間的一個(gè)因素。隨著消除機(jī)械手需要的開模間隙減少了,隨著模具行程的減少還提高了空循環(huán)速度。</p><p>　　系統(tǒng)

50、的另一個(gè)好處是需要的地板面積減少,以及由于沒有機(jī)械手和引出板冷卻系統(tǒng),系統(tǒng)的可靠性得以提高的潛力。預(yù)計(jì)不發(fā)生機(jī)械手故障的整個(gè)系統(tǒng)可靠性可允許系統(tǒng)可用性提高30%。轉(zhuǎn)位系統(tǒng)的地板面積只有傳統(tǒng)48 陰模系統(tǒng)所需面積的55%。與之相伴的還有每英尺地板面積的產(chǎn)量進(jìn)一步提高。</p><p>　　使用轉(zhuǎn)位系統(tǒng)使瓶胚的澆口質(zhì)量得到改進(jìn)。在閥澆口區(qū)冷凍之后,瓶胚在較短時(shí)間內(nèi)與閥桿的熱點(diǎn)接觸,因?yàn)槠颗咴陉幠?nèi)的冷卻時(shí)間被大大減少

51、。去掉這一熱源就消除一個(gè)結(jié)晶源。除了較好的視覺效果,還導(dǎo)致澆口區(qū)更結(jié)實(shí),從而使得整個(gè)瓶側(cè)壁區(qū)更好,及有更多的機(jī)會(huì)減輕基礎(chǔ)區(qū)瓶胚的重量。</p><p>　　瓶胚留在模芯較長(zhǎng)時(shí)間。與標(biāo)準(zhǔn)瓶胚注塑系統(tǒng)相比,整個(gè)瓶胚冷卻得到改進(jìn)。在一個(gè)傳統(tǒng)的機(jī)械手冷卻板內(nèi),制件遇到被冷卻的管表面就會(huì)收縮,這樣熱傳遞就不完美。在轉(zhuǎn)位系統(tǒng)中,制作在模芯上收縮,從而保持熱傳遞,在被頂出時(shí),轉(zhuǎn)位瓶胚的全面整體溫度比瓶胚從傳統(tǒng)系統(tǒng)的引出位置取出

52、時(shí)要低。還有,對(duì)于目前的瓶胚設(shè)計(jì)來說,不向頸模圈區(qū)供應(yīng)冷卻水,在頂出時(shí)仍比標(biāo)準(zhǔn)系統(tǒng)要冷得多。對(duì)于一個(gè)典型的成型系統(tǒng)來說,冷卻該區(qū)能限制循環(huán)。</p><p>　　轉(zhuǎn)位系統(tǒng)用幾種不同材料及測(cè)試的兩種不同材料和兩種不同的聚對(duì)苯二甲酸乙二醇酯螺桿設(shè)計(jì),可以看到乙醛(AA)量一直較低。與注射量相比這一循環(huán)時(shí)間對(duì)注射裝置提出非常高的要求,注射裝置連續(xù)不斷地沖刷沒有一點(diǎn)滯留時(shí)間的螺桿。</p><p>

53、;　　由于模具內(nèi)的峰值陰模與兩個(gè)不同的螺桿相符,并與不同的加工設(shè)置一致,乙醛量到底有多低主要原因在于模具集料管。用目前的模具可以看到的第二個(gè)好處是有非常好的重量分布,從而允許在目前制件規(guī)格的允差內(nèi)把整個(gè)制件的重量降到最低程度。 </p><p>　　4、介紹IKB-MOULD設(shè)計(jì)的基礎(chǔ) </p><p>　　注塑模組成的分析處理分為兩部份 </p><p>　　設(shè)
