摘要
分析了香水蓋外殼塑件的結(jié)構(gòu)特點(diǎn),敘述了該塑件成型工藝、注射模的結(jié)構(gòu)和工作原理,其原理是:采用定距螺釘和彈簧進(jìn)行二次分型,用斜導(dǎo)柱外側(cè)抽芯,型芯頂出零件,進(jìn)料時(shí)采用潛伏式澆口進(jìn)料形式,當(dāng)開(kāi)模的時(shí)候,用球頭拉料桿把澆注系統(tǒng)凝料頂出,然后利用型芯內(nèi)抽推板推出塑件,合模時(shí)用彈簧先復(fù)位,然后進(jìn)行下一次成型開(kāi)始。提高了生產(chǎn)效率。
關(guān)鍵詞:香水蓋;注射模;定距螺釘;彈簧;斜導(dǎo)柱;側(cè)抽芯;型芯;球頭拉料桿;推板
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
