传统的注塑模具设计,主要为二维和经验设计,单使用二维工程图纸已很难正确和详尽地表达产品的形状和结构,且无法直接应用于数控加工,设计过程中分析、计算周期长,准确性差。随着CAD/CAE/CAM技术的发展,现代注塑模具设计方法是设计者在电脑上直接建立产品的三维模型,根据产品三维模型进行模具结构设计及优化设计,再根据模具结构设计三维模型进行NC编程。这种方法使产品模型设计、模具结构设计、加工编程及工艺设计都以3D数据为基础,实现数据共享,不仅能快速提高设计效率,而且能保证质量,降低成本。注塑模具的设计是一个经验性很强的题目,由于设计经验有限,很难一次性应用三维造型软件UG/MoldWizard直接进行设计。
The traditional injection mold design is mainly two-dimensional and empirical design. It is difficult to express the shape and structure of the product correctly and detailedly by using two-dimensional engineering drawings alone, and it can not be directly applied to numerical control processing. The analysis and calculation cycle in the design process is long, and the accuracy is poor. With the development of CAD / CAE / CAM technology, the modern injection mold design method is that the designer directly establishes the 3D model of the product on the computer, carries on the mold structure design and the optimized design according to the 3D model of the product, and then carries on the NC programming according to the 3D model of the mold structure design. This method makes the product model design, mold structure design, processing programming and process design based on 3D data, and realizes data sharing, which can not only improve the design efficiency, but also ensure the quality and reduce the cost. The design of injection mold is a subject with strong experience. Due to the limited design experience, it is difficult to directly design with UG / Moldwizard.
