style="text-indent:25px">射成型是塑料加工中**普遍采用的方法。該方法適用于全部熱塑性塑料和部分熱固性塑料，制得的塑料制品數(shù)量之大是其它成型方法望塵莫及的，作為注射成型加工的主要工具之一的注塑模具，在質(zhì)量精度、制造周期以及注射成型過程中的生產(chǎn)效率等方面水平高低，直接影響產(chǎn)品的質(zhì)量、產(chǎn)量、成本及產(chǎn)品的更新，同時(shí)也決定著企業(yè)在市場(chǎng)競(jìng)爭(zhēng)中的反應(yīng)能力和速度。 ◆注塑模具是由若干塊鋼板配合各種零件組成的，基本分為： A 成型裝置（凹模，凸模） B 定位裝置（導(dǎo)柱，導(dǎo)套） C 固定裝置（工字板，碼?？樱?D 冷卻系統(tǒng)（運(yùn)水孔） E 恒溫系統(tǒng)（加熱管，發(fā)熱線） F 流道系統(tǒng)（唧咀孔，流道槽，流道孔） G 頂出系統(tǒng)（頂針，頂棍）塑料模具網(wǎng)站</p><div

style="text-indent:25px">塑性變形失效塑料模型腔表面受壓、受熱可引起塑性變形失效，尤其是當(dāng)小模具在大噸位設(shè)備上工作時(shí)，更容易產(chǎn)生超負(fù)荷塑性變形。塑料模具所采用的材料強(qiáng)度與韌性不足，變形抗力低；塑性變形失效另一原因，主要是模具型腔表面的硬化層過薄，變形抗力不足或工作溫度高于回火溫度而發(fā)生相變軟化，而使模具早期失效。 3）斷裂斷裂的主要原因是由于結(jié)構(gòu)、溫差而產(chǎn)生的結(jié)構(gòu)應(yīng)力、熱應(yīng)力或因回火不足，在使用溫度下，使殘余奧氏體轉(zhuǎn)變成馬氏體，引起局部體積膨脹，在模具內(nèi)部產(chǎn)生的組織應(yīng)力所致。 </p><p style="text-indent:25px">鏡面加工性能型腔表面光滑，成型面要求拋光成鏡面，表面粗糙度低于Ra0.4μm，以保證塑料壓制件的外觀并便于脫模。 6）熱處理性能在模具失效事故中，因熱處理造成的事故一般是52．3%，以致熱處理在整個(gè)模具制造過程中占有重要的地位，熱處理工藝的好壞對(duì)模具質(zhì)量有較大的影響。一般要求熱處理變形小，淬火溫度范圍寬，過熱敏感性小，特別是要有較大的淬硬性和淬透性等等。 7）耐腐蝕性在成形過程中可能放出腐蝕氣受熱分解出具有腐蝕性的氣體，如HC1、HF等腐蝕模具，有時(shí)在空氣流道口處使模具銹蝕而損壞，故要求模具鋼有良好的耐蝕性。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

①成型零件，包括凹模、凸模、各種成型芯，都是成型制品內(nèi)、外表面或上、下端面、側(cè)孔、側(cè)凹和螺紋的零件。 ②支承固定零件，包括模座板、固定板、支承板、墊塊等，用以固定模具或支承壓力。 ③導(dǎo)向零件，包括導(dǎo)柱和導(dǎo)套，用以確定模具或推出機(jī)構(gòu)運(yùn)動(dòng)的相對(duì)位置。 ④抽芯零件，包括斜銷、滑塊等，在模具開啟時(shí)用以抽出活動(dòng)型芯，使制品脫模。 ⑤推出零件，包括推桿、推管、推塊、推件板、推件環(huán)、推桿固定板、推板等，用以使制品脫模。注塑模多推廣采用標(biāo)準(zhǔn)模架，這種模架是由結(jié)構(gòu)、形式和尺寸都已標(biāo)準(zhǔn)化和系列化的基本零件成套組合而成，其模腔可根據(jù)制品形狀自行加工。采用標(biāo)準(zhǔn)模架有利于縮短制模周期。塑料模具網(wǎng)站</p><p
