模具毕业设计 摘要

摘要

模具属于精密机械的产品，它主要机械零件和机构组成。如成形工作零件、导向零件、定位零件、支撑零件及送料机构、抽芯机构、推出机构等。模具与相应的成形设备（如冲床、塑料注射机、压铸机等）配套使用时，可直接改变金属或非金属材料的形状、尺寸、相对位置和性能，使之成形为合格的制件。

模具设计是模具制造的基础，合理正确的设计是正确制造模具的保证：模具制造技术的发展对提高模具质量、使用寿命、精度以及缩短制造模具周期具有重要的意义：模具的质量、使用寿命、制造精度及合格率在很大程度上取决于制造模具的材料及热处理工艺：模具成本直接关系到制件的成本以及模具生产企业的经济效益；模具工作零件的精度决定制件的精度；模具的寿命又与模具材料及热处理、模具结构以及所加工制作材料等诸多因素有关；模具的安装与使用直接关系到模具的使用性能及安全；而模具的标准化是模具设计与制造的基础，对大规模、专业化生产模具具有极重要的作用，模具标准化程度的高低是模具工业发展水平的标志。

本次设计绘图采用CAXA进行，CAXA为计算机辅助制图工具，是一款专业机械平面制图软件，具有很强的图像处理功能。

Abstract

Mold products are precision machinery, it mainly consists of mechanical parts and bodies，such as forming working parts, parts orientation, positioning parts, supporting parts, positioning components and feed mechanism, core-pulling mechanism, introduced institutions. Mold and the corresponding forming equipment (such as punching, plastic injection machine, die-casting machine, etc. ) supporting the use of, may directly alter the shape of metal or non-metallic materials, size, relative position and performance, shaping the work piece for qualified.

Mold manufacturing mold design is the basis for rational design of the right mold to ensure correct; mold manufacturing technology to improve the mold quality, service life, accuracy and shorten the manufacturing cycle is of great significance mold; mold quality, service life, manufacturing precision and the passing rate depends largely on the manufacture of mold materials and heat treatment; mold costs directly related to the work piece, the cost and economic efficiency of enterprises mold; determine the accuracy of the die components parts precision; dies life expectancy and the mold materials and heat treatment, mold structure and the production of materials processing, and many other factors; and mold die design and manufacturing and use of mold performance and safety; and mold die design and manufacturing standards are the basis of the same, large scale, specialized production mold is a very important role in standardization of the level of mold is a sign of mold level of industrial development.

The use of caxa for design and drawing, caxa tool for computer aided drawing, is a professional mechanical surface mapping software, has a strong image processing functions.
