style="text-indent:25px">塑膠模具填充物：1、合成樹脂是塑料的主要成分，其在塑料中的含量一般在40%~99%。由于含量大，而且樹脂的性質(zhì)常常決定了塑料的性質(zhì)，所以人們常把樹脂看成是塑料的同義詞。例如把聚氯乙烯樹脂與聚氯乙烯塑料、酚醛樹脂與酚醛塑料混為一談。其實樹脂與塑料是兩個不同的概念。樹脂是一種未加工的原始聚合物，它不僅用于制造塑料，而且還是涂料、膠粘劑以及合成纖維的原料。而塑料除了極少一部分含99%的樹脂外，絕大多數(shù)的塑料，除了主要組分樹脂外，還需要加入其他物質(zhì)。2、填料填料又叫填充劑，它可以提高塑料的強度和耐熱性能，并降低成本。例如酚醛樹脂中加入木粉后可降低成本，使酚醛塑料成為廉價的塑料之一，同時還能卓著提高機械強度。填料可分為有機填料和無機填料兩類，前者如木粉、碎布、紙張和各種織物纖維等，后者如玻璃纖維、硅藻土、石棉、炭黑等。清遠快速模具模具工業(yè)是無以倫比的"效益放大器"。</p><div

style="text-indent:25px">注塑模具是生產(chǎn)各種工業(yè)產(chǎn)品的重要工藝裝備，隨著塑料工業(yè)的迅速發(fā)展，以及塑料制品在航空、航天、電子、機械、船舶和汽車等工業(yè)部門的推廣應(yīng)用，產(chǎn)品對模具的要求也越來越高，傳統(tǒng)的模具設(shè)計方法已無法適應(yīng)當(dāng)今的要求. 與傳統(tǒng)的模具設(shè)計相比，計算機輔助工程(CAE)技術(shù)無論是在提高生產(chǎn)率、保證產(chǎn)品質(zhì)量方面，還是在降低成本、減輕勞動強度方面，都具有極大的優(yōu)越性。注塑模具在加工中，各種數(shù)控加工均有用到，應(yīng)用多的是數(shù)控銑及加工中心，數(shù)控線切割加工與數(shù)控電火花加工在模具數(shù)控加工中的應(yīng)用也非常普遍，線切割主要應(yīng)用在各種直壁的模具加工，如沖壓加工中的凹凸模，注塑模中的鑲塊、滑塊，電火花加工用的電極等。對于硬度很高的模具零件，采用機加工辦法無法加工，大多采用電火花加工，另外對于模具型腔的尖角、深腔部位、窄槽等也使用電火花加工。而數(shù)控車床主要用于加工模具桿類標準件，以及回轉(zhuǎn)體的模具型腔或型芯，如瓶體、盆類的注塑模具，軸類、盤類零件的鍛模。在模具加工中，數(shù)控鉆床的應(yīng)用也可以起到提高加工精度和縮短加工周期的作用。</p><p style="text-indent:25px">注塑模具出現(xiàn)問題的原因：加工方面：1、加工壓力過大、速度過快、充料愈多、注射、保壓時間過長，都會造成內(nèi)應(yīng)力過大而開裂。2、調(diào)節(jié)開模速度與壓力防止快速強拉制件造成脫模開裂。3、適當(dāng)調(diào)高模具溫度，使制件易于脫模，適當(dāng)調(diào)低料溫防止分解。4、預(yù)防由于熔接痕，塑料降解造成機械強度變低而出現(xiàn)開裂。5、適當(dāng)使用脫模劑，注意經(jīng)常消除模面附著的氣霧等物質(zhì)。6、制件殘余應(yīng)力，可通過在成型后立即進行退火熱處理來消除內(nèi)應(yīng)力而減少裂紋的生成。材料方面：1、再生料含量太高，造成制件強度過低。2、濕度過大，造成一些塑料與水汽發(fā)生化學(xué)反應(yīng)，降低強度而出現(xiàn)頂出開裂。3、材料本身不適宜正在加工的環(huán)境或質(zhì)量欠佳，受到污染都會造成開裂。在成型過程中，塑件與模具接觸的面要比離開模具部分的尺寸穩(wěn)定性更好。</p><div
