【文章內(nèi)容簡介】 射壓力損失大，對深型腔塑件排氣不便。點(diǎn)澆口又稱針點(diǎn)澆口或菱形澆口，是一種截面尺寸很小的澆口，俗稱小澆口。這種澆口由于前后兩端存在較大的壓力差，可較大程度地增大塑料熔體的剪切速率并產(chǎn)生較大的剪切熱，從而導(dǎo)致熔體的表觀年度下降，流動(dòng)性增加，有利于型腔的填充，因而對于薄壁塑件以及諸如聚乙烯、聚丙烯等表現(xiàn)粘度隨剪切速率變化敏感的塑料成形有利，也不利于成形流動(dòng)性差及熱敏性塑料，也不利于成型平薄易變性及形狀非常復(fù)雜的塑件。鑒于上兩種方案難于取決，采用pro/，Plastics Insight 軟件套件是在對驗(yàn)證零件和模具設(shè)計(jì)進(jìn)行深入模擬方面的產(chǎn)品。能夠分析薄壁零件的 CAD 實(shí)體模型，這樣可以明顯降低模型準(zhǔn)備的時(shí)間。時(shí)間的節(jié)省能夠分析更多設(shè)計(jì)迭代以及執(zhí)行更深入的分析。分析條件：Part Name（零件名稱）:lingjiantuMaterial Supplier（材料供應(yīng)）:GenericMaterial Grade（材料結(jié)構(gòu)）:ABS AcrylonitrilebutadienestyreneMax Injection Pressure（最大注射壓力）: MPaMold Temperature（模具溫度）: Melt Temperature（材料溫度）: Model Suitability:Part model was highly suitable for analysis.分析結(jié)果：MoldingWindow Results方案一Manufacturer(制造性能）GenericConfidence（可行度）PoorMoldingWindowResults方案二Manufacturer（制造性能）GenericConfidence（可行度）Good填充分析：Filling Analysis方案一Moldability（模具性能）:Your part can be easily filled with acceptable quality using the current injection locations.Confidence:HighInjection Time: secInjection Pressure: MPaWeld Lines:NoAir Traps:YesShot Volume : Filling Clamp Force: tonnePacking Clamp Force Estimate @20%:( )MPa tonnePacking Clamp Force Estimate @80%:( )MPa tonnePacking Clamp Force Estimate @120%:( )MPa tonneClamp Force Area: Cycle Time: secFilling Analysis方案二Moldability:Your part can be easily filled with acceptable quality using the current injection locations.Confidence:HighInjection Time: secInjection Pressure: MPaWeld Lines:NoAir Traps:YesShot Volume : Filling Clamp Force: tonnePacking Clamp Force Estimate @20%:( )MPa tonnePacking Clamp Force Estimate @80%:( )MPa tonnePacking Clamp Force Estimate @120%:( )MPa tonneClamp Force Area: Cycle Time: sec縮痕分析：Sink Mark Analysis方案一Sinkability:2 % of your model was found to be prone to sink marks.
