Abstract

In enterprises engaged in the production of complex injection molding equipment, there is an interest and need in predicting the behavior of the final product. During commissioning, almost 100% of the molds are modified. In modern realities, a large number of injection moldings with various add-ons, functions and calculation methods are presented for analysis. The article provides an overview of a modern CAD/CAE system for the analysis of injection molding of plastics, which allows reducing the final cost of the product, reducing the production time of equipment and pre-production time. Using the example of equipment for a mass-produced part, the capabilities of the system are considered, methods for constructing meshes are high-lighted, and the features of modeling the filling process are shown. Software for engineering calculations using numerical methods (CAE systems) for injection molding of thermoplastic materials and special casting technologies provides extensive opportunities to predict and prevent production problems and reduce costs, not only from the point of view of tooling production, but also from the point of view technological process. With the help of analysis, it is possible to highlight temperature characteristics, filling time, pressure holding curve, cooling time and coolant flow to obtain quality parts from the first castings. To effectively use this software, it is necessary to take into account a set of factors that influence both the obtained quantitative calculation results and their qualitative assessment in relation to the characteristics of a specificт task. The results obtained during computer analysis directly depend on the consideration of the features of the process modeling methods, the conditions for performing calculations and the functional capabilities of the software product.
