摘要
 
分析了香水盖外壳塑件的结构特点，叙述了该塑件成型工艺、注射模的结构和工作原理，其原理是：采用定距螺钉和弹簧进行二次分型,用斜导柱外侧抽芯,型芯顶出零件,进料时采用潜伏式浇口进料形式,当开模的时候,用球头拉料杆把浇注系统凝料顶出,然后利用型芯内抽推板推出塑件,合模时用弹簧先复位,然后进行下一次成型开始。提高了生产效率。

Abstract

Analyzed the structure characteristics of the perfume cover outer shell plastics piece， described the  piece’s structure and work principle which model a craft and inject a mold， its principle ：adopt and certainly be apart from bolt and spring coil and carry on two cents type， use inclined lead a side outside the pillar and take out heart， type the heart crest spare parts， while entering and anticipating adoption incubate the type sprinkle into anticipate a form， while opening a mold， with the ball head pull and anticipate a pole sprinkle and note system  and anticipate， then make use of and take out and push plank and release a plastics piece inside a heart，use spring coil and reset first while matching a mold， then carry on willing model a beginning next time.Raised to produce an efficiency.
Keyword：perfume cover；inject a mold；certainly be apart from bolt；spring coil； inclined to lead pillar；the side takes out heart；type heart；the ball head pulls to anticipate a pole；push plank
