杯型件塑料成型工艺及模具设计
摘要
本设计题目为杯型注塑模设计，体现了深薄壁类塑料零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者注塑模设计的基础知识，为设计更复杂的注塑模具做好了铺垫和吸取了更深刻的经验。
本设计运用塑料成型工艺及模具设计的基础知识，首先分析了塑件的成分及性能要求，为选取浇口的类型做好了准备；然后估算了塑件的体积，便于选取注塑机及确定型腔数量；最后分析了塑件的特征，确定模具的设计参数、设计要点及推出装置的选龋
考虑到制件的结构，以及大批量生产，且外部要求具有一定的美观性。本设计需要用点
浇口的方式成型工艺方案，又因杯型件带有把手，所以型腔需要侧向分型瓣合式结构，推件方式选择推件板加推杆组合式推出，推杆在型芯上。开模时，斜导柱作用于侧型芯向两侧移动，进行侧向分型，侧向分型结束后，由卸料螺钉作用于推件板与型芯中的推杆同时推出塑件。这种机构脱模可靠，设计方便且在模具中占用空间较小，非常适合在本副模具中使用。

Design of injection mold parts cup
Abstract
This design topic for cup type of injection mold design,reflecting the deep thinwall plastic parts design requirements,content and direction,there are certain design significance.Through the design of the die parts,to further strengthen the designers of injection mold design basic knowledge,for more complexdesign of injection mold has laid a good groundwork and the more profound lessons of experience.
The design of the use of plastic forming process and die design of the basic knowledge,the first analysis of the plastic parts composition and performance requirements,readyfor the selection of the type of the gate; and estimated the plastic parts of the size,facilitate the selection of injection molding machine and determine the number of cavity; finally,analysis of the plastic parts of the characteristics to determine the parameters of mold design,design points and launch device selection.
Taking into account the structure of the parts,aswell as large quantities of production,and the external requirements of a certain aesthetic.
After the gatewayof forming process and for cup type component is providedwith a handle,so cavitylateral typevalve structure,pushing a selection push plate and the push rod combined launched,push rod in the core.When the mould is opened,slanted guide pillar role in the side core moving to the side,side to the sub type,the type of lateral end,the unloading action of the feed screwto push the handspike plate and core at the same time,the introduction of plastic parts.The ejection mechanism is reliable,convenient design and in the mold occupyless space,verysuitable for in this pair of moulds.
