The modular design of the mold

Shorten the design cycle and improve design quality is the key to shorten the development cycle of the entire mold. Modular design is the use of product components in the structure and function of similarity, and to achieve product standardization. A lot of practice shows that the modular design can effectively reduce product design time and improve design quality. Therefore, this paper explore the use of modular design in the mold design.
 
At firt: Establish module library
 
Establishing module library has three steps: module division, structural features and user-defined models feature generation. Standard Parts is a special case module exists in the module library. Simply define a standard part of two-step post. Module division is the first step in a modular design. Module division is reasonable, directly affect the function of the modular system, performance and cost. Each module is divided products must undergo technical research and repeated demonstration in order to obtain results of divisions. For the mold, the functional modules and structural modules are mutually inclusive. Structure of the module may have a greater range in the local structural change, so that it can contain functional module; and the local structure of the functional blocks may be more fixed, so that it may comprise structure modules. After completion of the module design, the Pro/ E of part/ assembly(Part/ Assembly) feature model space required manual construction of the module, using user of Pro/ E features a custom function, the custom module two variable parameters: Can change the size and assembly relationships form the user-defined features (User-Defined Features, UDFs). Generate user-defined profiles (in gph file suffix) was named by packet technology to store, to complete the setup module library.
 
Then: Module Base Management System
 
System through two inference, reasoning and structure select automatic modeling module, enabling determining module. The first module of the general structure of reasoning, the second inference to finalize all the parameters of the module. Implement the module " plasticity " target in this way. Select the reasoning in the structure, the system accepts user input module name, function and structure parameters, reasoning , and seek suitable module name in the module library.
If you are not satisfied with the result, the user can specify the module name. In this step, the resulting module is still uncertain, it is ill-defined size parameters, accuracy, material characteristics and assembly relationships. In the automatic modeling reasoning, the system uses the size of the input parameters, precision characteristics, material characteristics and the definition of assembly relationships, driving user-defined feature models dynamically and automatically configured out of the module features model and automated assembly. Automatic modeling function using C language and Pro/ E secondary development tool Pro/ TOOLKIT developed. You can quickly complete the mold design by calling the module. After applying this system mold design period is shortened. Because the module is designed to seriously consider the quality of the modules, so the quality of the mold plays a fundamental guarantee. Module library is stored in separate UDFs file, so the system is scalable.
