【最新版】水杯盖注塑模说明书毕业设计论文

摘 要

此次的设计任务即水杯盖注射模具设计，零件模型就是商场里面买来的大口杯。 产品的 3D建模，借助 PROENGINEER设计软件创建型腔、活块以及其他零件，并自动生成所需要的零件工程图 ；使用草图和厚度检测，评估零件；直接参照产品三维模型,创建分模曲面及滑块，再生成模具型腔组件（动模、定模）；对于模架的设计,利用 PROE模座专家EMX4.1来完成,从标准模架选择到产品输出,全部采用 3D化设计。我在水杯盖模具设计过程中，从零件建模到型腔、型芯的设计、模架设计，直至最后的模具开模动作模拟都充分发挥了 PROENGINEER设计软件的各个模块和插件的优势，基本做到了无图纸化设计。采用一模四腔的设计。注塑机综合注塑容量、锁模力、最大注塑面积和模内压力标准件选用Misumi。使用了模具设计软件——PROENGINEER，从最初的零件 3D建模到最后的模具各部分零件的装配，模座设计,工程图文件,依靠 PROENGINEER的各个模块,得到合乎毕业设计规范的工程图。

模具的特点是：滑块在动模，斜导柱在定模，以保证顺利完成侧向抽芯。此外，还对工作零件和注射机有关参数进行了必要的校核计算。 关键词：模具，注塑件，PROE，EMX，生产实践

ABSTRACT

This task is the design of cupcover's injection mold design. Parts model is the common one in super market.

Products of 3 D modeling, with the aid of the PROe design software to create cavity, live piece and other parts, and the engineering drawings is automatic generated ; the parts is evaluated by sketches and the thickness detect. Referring to the product directly 3 d model, parting surface, the slider, the mold cavity components (mold core, and the mold cavity) are created. From standard formwork choose to product output, 3D design is used, such as using PROE mould seat experts EMX4.1 to complete for the design of the formwork. From parts modeling to cavity, cores of design, formwork design, until the last of the mould cavity movement simulation are taken full of the PROe design software modules and plug-in advantage. machine Comprehensive injection capacity, injection molding machine clamping force, and maximum injection area and mould pressure technology parameters. Futaba is choosed as Mold base, other standard parts are selected Misumi. Using the die design software-PROe, from the initial part 3D modeling to the end of the mould parts of the assembly parts, mould seat design, engineering drawings files are all relied on PROe modules to get with the engineering drawings that meet the graduation project standard.

The characteristics of the mould is that the slider in dynamic model, oblique guide column in the mold, to ensure smooth finish side core-pulling. In addition, the necessary relevant parameters checked calculation of the work parts and injection machine.

Key words: Mold，Injection part，PROE，EMX，Practical product
