基于Inventor的世赛模具成型零件工作尺寸计算

Calculation of the World Skills International Molding Parts Size Based on Inventor

如何确定塑件的公差,针对有公差的塑件如何计算模具成型零件工作尺寸,已经成为许多模具专业师生面临的问题。本文针对第42届世界技能大赛模具制造项目的试题,解决塑件精度的确定和模具成型零件工作尺寸的计算,同时针对本次大赛采用的软件,用Inventor来探究塑件有精度时模具设计的技巧。

How to determine the plastic products of tolerance, how to calculate the molding parts of plastic products with tolerances, has become a problem facing many mold professional teachers and students. Aiming at the forty-second session of the world skills competition mold manufacturing test items, this paper will solve the calculation and molding parts size precision of plastic products, at the same time for the contest by software, use Inventor to research mold design skills for products with high precision.
