NXOpen-based human-computer interaction design system development for lateral core extraction mechanism of inclined guide pillar

Abstract

The core extraction mechanism is one of the key components of a mold, and its design accuracy not only affects the production quality of molded parts, but also plays a key role in the service life of the mold. The traditional core extraction mechanism design process has low automation, tedious steps, difficult work, and can lead to a series of problems such as long mold design cycle and low production efficiency. Therefore, this study introduces intelligent CAD technology into the core extraction mechanism design process and develops a complete human-computer interaction design interface for the inclined column side core extraction mechanism, which is applicable to both die-casting and injection molds and greatly improves the efficiency of mold design. Firstly, we designed the corresponding feature recognition algorithm by two methods of "graph-based feature recognition" and "surface-based feature recognition", and developed the intelligent feature recognition subsystem. Secondly, based on the feature data of the molded parts and the principle of core extraction mechanism design, the parametric design module of each component of the lateral core extraction mechanism of the inclined guide pillar is developed. Finally, the reliability and rationality of the parametric drive design of the system are verified by the CAE motion simulation module of UG. The system is applicable to the design of core extraction mechanism of die-casting and injection molds, which greatly simplifies the tedious work of modeling the core extraction mechanism of inclined guide pillar and improves the efficiency of mold design.
