旋钮注塑模的设计(含零件图,装配图)

旋钮注塑模的设计(含零件图,装配图)(含任务书,毕业论文说明书10000字,cad图纸5张零件图1张装配图)
摘 要
本设计的题目是旋钮注塑模设计，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，内部不得有导电杂质，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，选用侧浇口比较合适，设计时，考虑选择从壁厚3mm处进料，料从厚处向薄处流，且该模具型芯采用组合式结构，有利于填充、排气。
凸模主要是成形制件的内表面，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，本模具采用一模四件的结构形式；凹模主要成型塑件外表面，结构较简单，将凹模设计成组合式结构，既保证塑件外观与质量，模具加工也比较方便。
由于设计者的能力有限，设计中存在很多不足之处，还望老师给予指教和谅解。
关键词：塑件表面、一模六腔、组合式型腔、侧浇口。

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. [资料来源：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 芯 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 phrase:The part have sixe, molding  sectional types , sides sprinkle.
