选择浇口位置的技巧入水口选择浇口对制件的影响及位置的选择一、浇口位置的要求：1.外观要求(浇口痕迹,熔接线)2.产品功能要求3.模具加工要求4.产品的翘曲变形5.浇口容不容易去除二、对生产和功能的影响：1.流（FlowLength）决定射出压力，锁模力，以及产品填不填的满流长缩短可降低射出压力及锁模力2.浇口位置会影响保压压力保压压力大小保压压力否平衡将浇口远离产品未来受力位置（如轴承处）以避免残留应力浇口位置必须考虑排气，以避免积风发生不要将浇口放在产品较弱处或嵌入处，以避免偏位（CoreShaft）三、选择浇口位置的技巧1.将浇口放置于产品最厚处，从最厚处进浇可提供较佳的充填及保压效果。如果保压不足，较薄的区域会比较厚的区域更快凝固避免将浇口放在厚度突然变化处，以避免迟滞现象或是短射的发生2.可能的话，从产品中央进浇将浇口放置于产品中央可提供等长的流长流长的大小会影响所需的射出压力中央进浇使得各个方向的保压压力均匀，可避免不均匀的体积收缩3澆口(Gate)澆口是一條橫切面面積細小的短槽,用以連接流道與模穴.橫切面面積所以要小,目的是要獲得以下效果:1.模穴注不久,澆口即冷結.2.除水口簡易.3.除水口完畢,僅留下少許痕跡4.使多個模穴的填料較易控制.5.減少填料過多現象.1.3.1設計澆口的方法並無硬性規定,大都是根據經驗而行,但有兩個基本要素須加以折衷考慮:1.澆口的橫切面面積愈大愈好,而槽道之長度則愈短愈佳,以減少塑料通過時的壓力損失.2.澆口須細窄,以便容易冷結及防止過量塑料倒流.故此澆口在流道中央,而它的橫切面應盡可能成圓形.不過,澆口的開關通常是由模件的開關來決定的.1.3.2澆口尺寸澆口的尺寸可由橫切面積和澆口長度定出,下列因素可決定澆口最佳尺寸:1.膠料流動特性2.模件之厚薄3.注入模腔的膠料量4.熔解溫度5.工模溫度1.3.3決定澆口位置時,應緊守下列原則:1.注入模穴各部份的膠料應盡量平均.2.注入工模的膠料,在注料過程的各階段,都應保持統一而穩定的流動前線.3.應考慮可能出現焊痕,氣泡,凹穴,虛位,射膠不足及噴膠等情況.
