style="text-indent:25px">注塑模具頂桿彎曲、斷裂或者漏料的問(wèn)題：自制的頂桿質(zhì)量較好，就是加工成本太高，現(xiàn)在通常選用標(biāo)準(zhǔn)件，質(zhì)量一般。頂桿與孔的間隙如果太大，則出現(xiàn)漏料；但如果間隙太小，在注射時(shí)由于模溫升高，頂桿膨脹而卡死。更危險(xiǎn)的是，有時(shí)頂桿被頂出一段距離就頂不動(dòng)而折斷，結(jié)果在下一次合模時(shí)，這段露出的頂桿不能復(fù)位而撞壞凹模。為了解決這個(gè)問(wèn)題，頂桿重新修磨，在頂桿前端保留10~15毫米的配合段，中間部分磨小0.2毫米。所有頂桿在裝配后，都必須嚴(yán)格檢查其配合間隙，一般在0.05~0.08毫米內(nèi)，要保證整個(gè)頂出機(jī)構(gòu)能進(jìn)退自如。冷卻不良或水道漏水的問(wèn)題：模具的冷卻效果直接影響制品的質(zhì)量和生產(chǎn)效率，如冷卻不良，制品收縮大，或收縮不均勻而出現(xiàn)翹曲變形等缺陷。另一方面，模具整體或局部過(guò)熱，使模具不能正常成型而停產(chǎn)，嚴(yán)重者使頂桿等活動(dòng)件熱脹卡死而損壞。冷卻系統(tǒng)的設(shè)計(jì)、加工以產(chǎn)品形狀而定，不要因?yàn)槟＞呓Y(jié)構(gòu)復(fù)雜，或加工困難而省去這個(gè)系統(tǒng)，特別是大中型模具，一定要充分考慮冷卻問(wèn)題。</p><p style="text-indent:25px">模具的結(jié)構(gòu)雖然由于塑料品種和性能、塑料制品的形狀和結(jié)構(gòu)以及注射機(jī)的類(lèi)型等不同而可能千變?nèi)f化，但是基本結(jié)構(gòu)是一致的。模具主要由澆注系統(tǒng)、調(diào)溫系統(tǒng)、成型零件和結(jié)構(gòu)零件組成。其中澆注系統(tǒng)和成型零件是與塑料直接接觸部分，并隨塑料和制品而變化，是塑模中復(fù)雜，變化大，要求加工光潔度和精度高的部分。澆注系統(tǒng)是指塑料從射嘴進(jìn)入型腔前的流道部分，包括主流道、冷料穴、分流道和澆口等。成型零件是指構(gòu)成制品形狀的各種零件，包括動(dòng)模、定模和型腔、型芯、成型桿以及排氣口等。我國(guó)塑料模具在高技術(shù)驅(qū)動(dòng)和支柱產(chǎn)業(yè)應(yīng)用需求的推動(dòng)下，形成了一個(gè)巨大的產(chǎn)業(yè)鏈條，從上游的原輔材料工業(yè)和加工、檢測(cè)設(shè)備到下游的機(jī)械、汽車(chē)、摩托車(chē)、家電、電子通信、建筑建材等幾大應(yīng)用產(chǎn)業(yè)，塑料模具發(fā)展一片生機(jī)。吸塑模具因成型時(shí)壓力較低，模具材料多選用鑄鋁或非金屬材料制造，結(jié)構(gòu)較為簡(jiǎn)單。</p><div

style="text-indent:25px">審核模具的制造材料是否合適，相對(duì)應(yīng)的熱處埋工藝是否合理。通常，模具材料的熱處理工藝對(duì)其影響很大。如果模具的淬火溫度過(guò)高，淬火方法和時(shí)間不合理，以及回火次數(shù)和溫度、肘間選擇不當(dāng)，都會(huì)導(dǎo)致模具進(jìn)入沖壓生產(chǎn)后損壞。落料孔尺寸或深度設(shè)計(jì)不夠，容易使槽孔阻塞，造成落料板損壞。彈簧力設(shè)計(jì)太小或等高套不等高，會(huì)使彈簧斷裂、落料板傾斜．造成重疊沖打，損壞零件。沖頭固定不當(dāng)或螺絲強(qiáng)度不夠．會(huì)導(dǎo)致沖頭掉落或折斷。模具使用時(shí)，零件位置、方向等安裝錯(cuò)誤或螺栓緊固不好。工作高度調(diào)整過(guò)低、導(dǎo)柱潤(rùn)滑不足。送料設(shè)備有故障，壓力機(jī)異常等，都會(huì)造成模具的損壞。如果出現(xiàn)異物進(jìn)入模具、制件重疊、廢料阻塞等情況未及時(shí)處理，繼續(xù)加工生產(chǎn)，就很容易損壞模具的落料板、沖頭、下模板和導(dǎo)柱。江蘇模具制造</p><p
