摘要
如今，塑料产品的上市时间变的越来越短，因此，制造注塑模的可用交货时间也变的少了。在模具的设计阶段有个省时的潜在方法，因为由于每个模具设计可以是标准化的，所以一个设计程序可以被重复使用。本文提出了一种通过使用标准模版来控制几何参数的方法来设计注塑模的型腔布局。标准模版的型腔布局设计包括可能布局的配置。每个布局设计的配置都有其特有的由所有几何参数构成的布局设计表格。这个标准模版是预定义在合型设计的布局设计的级别时的。这样就能够确保要求的配置能够被快速地输入到模具装配设计中，而不需要重新设计布局。这使得它在模具制造前产品设计师和模具设计师之间的技术讨论上更有用。在讨论时直接改变3D型腔的布局设计，这样可以节省时间和避免错误传达。型腔设计的标准模版便于各个模具制造公司依照顾客具体要求而制造他们各自的规格。

A Parametric-Controlled Cavity Layout Design System for a Plastic Injection Mould

Today, the time-to-market for plastic products is becoming shorter, thus the lead time available for making the injection mould is decreasing. There is potential for timesaving in the mould design stage because a design process that is repeatable for every mould design can be standardised. This paper presents a methodology for designing the cavity layout for plastic injection moulds by controlling the geometrical parameters using a standardisation template. The standardization template for the cavity layout design consists of the configurations for the possible layouts. Each configuration of the layout design has its own layout design table of all the geometrical parameters. This standardisation template is pre-defined at the layout design level of the mould assembly design. This ensures that the required configuration can be loaded into the mould assembly design very quickly, without the need to redesign the layout. This makes it useful in technical discussions between the product designers and mould designers prior to the manufacture of the mould. Changes can be made to the 3D cavity layout design immediately during the discussions, thus saving time and avoiding miscommunication. This standardisation template for the cavity layout design can be customised easily for each mould making company to their own standards.
