泡沫灭火器喷嘴注塑模设计(含工艺卡片,cad零件图和装配图)(含任务书,开题报告,中期检查表,论文说明书12000字,CAD图纸7张)
摘 要
本设计的题目是泡沫灭火器喷嘴，通过塑件的工艺分析、注塑模结构设计及有关计算、模具闭合高的的确定、注塑机有关参数的校核等，该模具基本符合要求。
该塑件要求表面没有毛刺、凹陷等缺陷，没有其它特别要求，故注塑较易实现。根据塑件的成型要求及模腔的排列方式，选用潜伏式浇口比较合适，该模具型芯采用组合式结构，有利于填充、排气。
型芯主要是成形制件的内表面，本模具把型芯固定在定模一侧，这样可以简单模具的结构。考虑加工的难易程度和材料的价值利用、塑件的形状和尺寸，并考虑到塑件的生产率，本模具采用一模二件的结构形式；凹模主要成型塑件外表面，结构较简单，将型腔设计成组合式结构，既保证塑件外观与质量，模具加工也比较方便。从塑件结构上看，将型腔与斜滑块设计在一起，组成一个抽芯机构。
关键词：一模二腔、组合式型腔、斜滑块抽芯、 潜伏式浇口。

Take off to want
  The topic of this design is a knob to note the mold of part designs, the piece of part craft analysis, and the mold construction design and relevant calculation, the molding tool shuts to match high really settle, note the machine of the concerning parameter etc., that molding tool is basic to meet the request. [资料来源：http://www.doc163.com]
  The part's piece requests the surface has no the hair stabs, hollow etc. blemish, inner part cannot conduct electricity the miscellaneous quality, have no other special request, so note the part than realizes easily.According to an alignment for modeling request and moldings method, choose to sprinkle with the side comparison accommodation, design, consider the choice from the wall the thick 3 mms enters to anticipate, anticipate to flow to thin place from the thick place, and the molding tool's type adopts the sectional construction, benefitting to fill , row spirit.
  The convex mold is a difficult easy degree to take shape a the piece of system inside surfaces, consider to process primarily with the material of worth a make use of, a rate of production for of shape with size, combining in consideration of the piece of the part , this molding tool adoption is sectional to model a mold six pieces constructions form;The cave mold models the part an outward appearance primarily, construction than simple, design the cave mold sectional construction, since guarantee the part an external appearance and quantity, the molding tool processes too more convenient.

Because design of ability limited, design inside exsit a lot of not enough places, still hope the teacher gives to advise with understand.
Key word:  A The mold two , inclined slippery pieces ,take out the and incubare ,the type to sprinkle.
