摘要:

在当前工程实际中,成型零件工作尺寸的计算普遍采用的是基于平均收缩率的计算方法.这种方法处理特殊情况,如材料的收缩率和模具的制造误差处于极限状态的情况下就存在有较大误差,因此提出以平均收缩率计算方法为基础,并考虑极限状态下的各种因素,对原有计算公式进行了修正.由于注塑件结构复杂,且模具成型零件尺寸数量巨大,因此采用特征造型技术,以AutoCAD为平台,采用Geometry/Feature相结合的方法,建立了注塑件特征信息模型,实现了由注塑件尺寸到模具成型零件工作尺寸的自动转换.

Abstract:

In the current engineering practice, the calculation method based on the average shrinkage rate is generally adopted for the calculation of the working size of the molded parts. This method deals with special cases, such as the shrinkage of materials and the manufacturing error of the mold in the limit state, so the original calculation formula is modified based on the average shrinkage calculation method and considering various factors in the limit state. Due to the complex structure of injection molded parts and the huge number of mold molded parts, the feature modeling technology is adopted, AutoCAD is used as the platform, and the method of combining Geometry/Feature is adopted to establish the characteristic information model of injection molded parts, which realizes the automatic conversion from the size of the injection molded parts to the working size of the molded parts.
