P摘要：本文是对四功能喷枪的卡头芯进行注射塑料模具设计，文中从制件和所用原材料分析入手，分析了卡头芯的注射成型工艺，进行了型腔的尺寸计算，论述了卡头芯模具结构设计，阐述了塑件分型面确定、型腔数量、排列方式、浇注系统和排气系统、塑件推出方式和位置、推出零件结构、浇注系统凝料推出方式、温度调节控制系统和成型零件及主要结构形式的设计过程。在设计中，考虑到本次所设计零件尺寸较小，精度要求不高，为提高生产率，故采用一模三十二腔。在此基本上，对主要零件进行了加工工艺分析，并编制了工艺过程卡，通过模具设计、制造，实现了卡头芯的注射成型。BR关键词：注塑成型；分型面；模具设计；工艺性分析 /P PAbstract and KeywordBRAbstract: This paper is carrying on designing the plastic injection mold with four function spray gun’ chuck core. This article commence at spare parts and chuck core’ material. It has analyzed the chuck core injection formation craft and calculated the size of the mode lumen, elaborated the mold of chuck core structural design, elaborated how to determined the parting surface， the quantity of mode lumens ，the arrangement way, the casting system，the exhaust gas system, the sprinkle way，position of design, the structure of sprinkle parts, how to sprinkle the casting system congeal material ,the temperature control system ,the formation parts and the main structural design process. In the design, because the spare parts size is small and the accuracy request isnt high, in order to rise the rate of production, we adopted one mould and 32 mode lumens. In this paper, it has carried on the processing craft analysis of the major parts, and established the technological process card, through the mold design and the manufacture, the chuck core injection formation has realized. p class=Yqe876/p BRKeyword：injection molding；parting surface；mold design；craft analysisBRBR1 四功能喷枪的工作原理BR将水管接头与四功能喷枪的奶嘴接上注入水，手捏喷枪的开关即可喷水。四功能喷枪的喷头上有四个不同的小孔，每旋转 即可分别得到四种不同类型 p class=Yqe876/p /P P的水花：柔水喷淋、急水喷淋、喷雾喷淋、全力喷淋四种功能水形。BR2 四功能喷枪的整体结构 BR四功能喷枪由ABS塑料制成,大体由枪体、开关、喷头、螺栓、螺母、盖板、垫片、奶嘴、弹簧、卡销芯等零部件组成。本设计主要是设计卡头芯两部 span class=Yqe876/span /P P分的注塑成型模具。其中重量为 。BR3 零件公差分析 BR塑件的尺寸精度主要决定于塑料的收缩率的波动和模具制造误差。查文献可取精度等级为一般等级4级，公差为0.012 。由于塑件成形时受种种原因的 span class=Yqe876/spa
