Algorithm for automatic parting surface extension in the mold design navigating process

Abstract

This study focused on the planning and development of an algorithm and process for automatic parting surface design under the CAD software architecture. Relating to the smooth opening of a mold, the parting surface is an important step of mold design. The parting surface can be categorized into the main parting surface and the shut-off parting surface. This study developed an algorithm of extension rules for the main parting surface and determined the contour vector and geometric relationship via computer software. It can realize the main parting surface automatic extension and can be embedded into a web-based mold design navigating process. Through a standardized design process, it can reduce the number of mouse clicks by 90%, enabling users to rapidly complete mold designs, reduce design errors, and improve efficiency.
