泡沫灭火器喷嘴的注塑成型工艺及模具设计
摘要
这次设计的题目是泡沫灭火器喷嘴的注塑成型工艺及模具设计，通过对塑件进行工艺分析和设计注塑模以及对结构的相关计算，对模具闭合高度的计算，对注塑机进行相关参数的检验和确定等，确定了该模具基本符合要求。
这个塑件要求表面光滑且没有凹陷没有毛刺，因为没有其它的特别要求，所以用注塑的方法比较容易实现。根据塑件的成型要求和模具型腔的布置，选择潜伏浇口更合适。型芯采用组合式结构，有利于充填和排气。
型芯主要是成型件的内表面。该模具将型芯固定在固定模具的一侧，可以简化模具的结构。考虑到加工难度和材料的价值利用，以及塑件的形状和尺寸，考虑到塑件的生产能力，该模具采用一模两块的结构。阴模主要形成塑料件的外表面，结构相对简单。空腔设计成组合结构，既保证了塑件的外观和质量，又便于模具的加工。从塑件的结构来看，空腔和倾斜滑块设计在一起，形成抽芯机构。

Abstract
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.
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.
Keywords: The mold two ;lined slippery pieces ;ake out the and incubare ;he type to sprinkle
