摘  要

注塑成型是塑件生产最常用的方法之一。本设计通过注塑模具产品，利用实体模型测量产品的尺寸，对实体进行建模，并对塑件的材料和塑件结构进行分析，并对塑件的模具进行设计，包括塑件成品的设计、工艺参数的分析与计算、工作部分的设计、模具结构的设计和加工方案的制定，确定塑件的最佳浇注位置，并通过实际情况进行调整，从而得到对实际生产来说最合理的浇注位置。在确定模具型腔数目后，分析产品的气穴、熔接痕、充填时间、充填结束时的体积温度、流动前沿处的温度、速度/时间转换点压力、充填结束时的压力、注射位置处压力等，可确定注塑模具的合理性。最后本运用ug 4.0及其EMX4.1模块来完成模具整体设计工作。

Abstract

Plastic shaping be used in common for plastic products to manufacture.Basing on the actual plastic products of electric blanket, the designer uses the actual model to measure the product, creates a model for the actual product and making an analysis to the materials and structure of  the product. Designs the plastic mould,  including the design of plastic finished product, analysis and account of craft parameter, the design of work piece, mould structure and the processing project. The designer focuses on the design and account work of parting-surface and slide. Using  the designer uses Moldflow Plastics Insight 6.1 to make an analysis of the product，deciding the best location. And making a increase Basing on actuality to get the best effect . After deciding the number of cavity for mold ，using Moldflow Plastics Insight 6.1 to make an analysis for air pocket，weld lines，fillingtime，bulk temperatures of sandouting，temperature at flow front，pressure at V/P switchover point，screen out pressure，pressure at injected location and so on， to sure the rationality of  mould design. The last using Pro-Engineer4.0 and EMX4.1 module is applied to the whole design.
