摘 要

模具由三个基本部分组成，分别是动模部分、型腔板、定模板。动模部分包括模板组件，支撑块，支撑板，推出机构和顶杆推出机构。这样设计的动模部分与最基本的模具结构中的动模部分相同。塑料注塑模具工艺是一个循环的过程，这个过程有四个重要的阶段：充模、压实、冷却和出模。从塑料注塑机器系统的漏斗到加热注塑，塑料注薂@尚凸ひ湛加谔畛涫髦褪实钡奶砑蛹痢３淠＞褪窍蚰＞咝颓怀渎鹊木酆咸搴腿廴谔澹谎故稻褪堑本酆咸迥毯螅蛐颓荒谧⑷虢细叩难沽酆咸逖故狄猿セ乖て诘氖账酰焕淙淳褪墙鹊木酆咸謇淙矗闫浯锏揭欢ǖ挠捕龋员隳鼙欢コ觯蛔詈缶褪峭瞥鼋锥危谡飧鼋锥沃校紫惹昂竽７挚芗欢コ觯缓竽＞哂趾夏＝胂乱淮窝贰Ⅻbr>要设计电扇开关罩壳侧抽芯塑料模具,许多重要的设计内容一定要被考虑进去。这些因素是塑件大小，型腔数目，型腔层次，分流道系统,浇铸系统，收缩和推出系统。以上这些也就是与我的毕业设计所要研究的主要内容。

Abstract

Separation of the mold by three basic components,each forming part,is the type plate,a template.it also include a component part,support and sustain its agencies,and its institutions.such a design of course part of the mold and the basic structure of part of the same mould.plastic injection mould a process is a recycling process.this process has four important stage：to mould,compacted,cooling,and a plastic mould.from the funnel of the machines to heat,moulding plastics,plastic molding forming technology began to fill the resin and suitable ingredients.to die cavity was full of mold is to type of aggregate and the molten；compacted together in a seemly congealed,to a cavity into a high pressure will get down to pay a seemly expected to shrink；Cooling is the hottest of the aggregation and cool, its degree of hardness to the top of the final stage is to launch；at this stage,the first time,plastic mould it was the top out, and to mould tool and enter the next cycle.
To be designed over the side of the electric fan switch socket plastic mould,many important design contents must be taken into consideration. these factors are maintaining a large number,type a and type a level,a distributary road systems,casting system,and introduce the system.These are my graduation project for the main content.
