文档介绍：计算器上盖注塑模具设计
摘要
塑料工业是当今世界上增长最快的工业门类之一,因而注塑模具得到飞速发展,因此,研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大的意义。本设计题目是计算器上盖模具设计,介绍了注塑成型的基本原理,特别是单分型面注塑模具的结构与工作原理;详细介绍了注射模具浇注系统、成型零件和顶出系统的设计过程。浇注系统主要对浇口道、主流道和分流道进行了设计;成型零件主要对凹模结构和工作尺寸进行了设计和计算,并对两处侧抽芯机构进行了重点分析和设计,这里采用了成型斜顶杆和橡胶完成,并对脱模力进行了计算,然后对模具强度要求、锁模力、最大注射量等做了校核;最后使用SolidWorks软件对模具的零件进行实体造型,同时完成了注射插装式控制回路的PLC设计。

Injection Mould Design of Calculator Cover
Abstract
The plastics industry is one of the fastest growing industrial branches in the world, so that the injection molds have rapid development, therefore, of molds reserchment about plastics production process and improve product quality have great significance. This topic is the calculator on the cover of the mould design, describes the basic principles of injection molding, especially single-parting molds structure and works; details the injection mold casting system, forming parts and ejection system design process. Casting system is mainly on gate road, mainstream road and branching channels design; prototyping part mainly on die structure and working size design and calculation, and two lateral pulling mechanism focused analysis and design, here is some oblique top rail and rubber, and stripping puted, and on tooling strength requirements, clamping force, maximum volume and so do check; last use SolidWorks software on mould parts solid modeling, pleted the injection cartridge PLC control circuit design.
Keywords:forming parts; ejection system; guiding-mechanism; injection molding
