style="text-indent:25px">塑膠模具產(chǎn)品填充：1、增塑劑增塑劑可增加塑料的可塑性和柔軟性，降低脆性，使塑料易于加工成型。增塑劑一般是能與樹脂混溶，無毒、無臭，對光、熱穩(wěn)定的高沸點(diǎn)有機(jī)化合物，常用的是鄰苯二甲酸酯類。例如生產(chǎn)聚氯乙烯塑料時(shí)，若加入較多的增塑劑便可得到軟質(zhì)聚氯乙烯塑料，若不加或少加增塑劑(用量<10%)，則得硬質(zhì)聚氯乙烯塑料。2、穩(wěn)定劑為了防止合成樹脂在加工和使用過程中受光和熱的作用分解和破壞，延長使用壽命，要在塑料中加入穩(wěn)定劑。常用的有硬脂酸鹽、環(huán)氧樹脂等。3、著色劑著色劑可使塑料具有各種鮮艷、美觀的顏色。常用有機(jī)染料和無機(jī)顏料作為著色劑。4、潤滑劑潤滑劑的作用是防止塑料在成型時(shí)不粘在金屬模具上，同時(shí)可使塑料的表面光滑美觀。常用的潤滑劑有硬脂酸及其鈣鎂鹽等。除了上述助劑外，塑料中還可加入阻燃劑、發(fā)泡劑、抗靜電劑等。</p><p style="text-indent:25px">注塑模具的熱平衡控制注塑機(jī)和模具的熱傳導(dǎo)是生產(chǎn)注塑件的關(guān)鍵。模具內(nèi)部，由塑料(如熱塑性塑料)帶來的熱量通過熱輻射傳遞給材料和模具的鋼材，通過對流傳遞給導(dǎo)熱流體。另外，熱量通過熱輻射被傳遞到大氣和模架。被導(dǎo)熱流體吸收的熱量由模溫機(jī)來帶走。模具的熱平衡可以被描述為:P=Pm-Ps。式中P為模溫機(jī)帶走的熱量;Pm為塑料引入的熱量;Ps為模具散發(fā)到大氣的熱量。控制模具溫度的目的和模具溫度對注塑件的影響注塑工藝中，控制模具溫度的主要目的一是將模具加熱到工作溫度，二是保持模具溫度恒定在工作溫度。以上兩點(diǎn)做的成功的話，可以把循環(huán)時(shí)間優(yōu)化，進(jìn)而保證注塑件穩(wěn)定的高質(zhì)量。模具溫度會影響表面質(zhì)量，流動性，收縮率，注塑周期以及變形等幾方面。模具溫度過高或不足對不同的材料會帶來不同的影響。對熱塑性塑料而言，模具溫度高一點(diǎn)通常會改善表面質(zhì)量和流動性，但會延長冷卻時(shí)間和注塑周期。模具溫度低一點(diǎn)會降低在模具內(nèi)的收縮，但會增加脫模后注塑件的收縮率。而對熱固性塑料來說，高一點(diǎn)的模具溫度通常會減少循環(huán)時(shí)間，且時(shí)間由零件冷卻所需時(shí)間決定。此外，在塑膠的加工中，高一點(diǎn)的模具溫度還會減少塑化時(shí)間，減少循環(huán)次數(shù)。模具的加工質(zhì)量與精度也就決定著這些產(chǎn)品的質(zhì)量。</p><div

style="text-indent:25px">注塑模具遇到的問題：1、澆口脫料困難：在注塑過程中，澆口粘在澆口套內(nèi)，不易脫出。開模時(shí)，制品出現(xiàn)裂紋損傷。此外，操作者必須用銅棒前端從噴嘴處敲出，使之松動后方可脫模，嚴(yán)重影響生產(chǎn)效率。這種故障主要原因是：澆口錐孔光潔度差，內(nèi)孔圓周方向有刀痕。其次是材料太軟，使用一段時(shí)間后錐孔小端變形或損傷，以及噴嘴球面弧度太小，致使?jié)部诹显诖颂幃a(chǎn)生鉚頭。澆口套的錐孔較難加工，應(yīng)盡量采用標(biāo)準(zhǔn)件，如需自行加工，也應(yīng)自制或購買專用鉸刀。錐孔需經(jīng)過研磨至Ra0.4以下。此外，必須設(shè)置澆口拉料桿或者澆口頂出機(jī)構(gòu)。2、導(dǎo)柱損傷：導(dǎo)柱在模具中主要起導(dǎo)向作用，以保證型芯和型腔的成型面在任何情況下互不相碰，不能以導(dǎo)柱作為受力件或定位件用。在以下幾種情況下，注射時(shí)動、定模將產(chǎn)生巨大的側(cè)向偏移力：塑件壁厚要求不均勻時(shí)，料流通過厚壁處速率大，在此處產(chǎn)生較大的壓力；塑件側(cè)面不對稱，如階梯形分型面的模具，相對的兩側(cè)面所受的反壓力不相等。塑料吸塑模具是以塑料板、片材為原料成型某些較簡單塑料制品的一種模具。北侖車燈模具制造生產(chǎn)廠家</p><p
