Intelligent Ball plastic injecting mold design
Abstract
This paper mainly describes the intelligent ball plastic's injection mold design which is made of ABS. Based on the process performance and the operation requirements of the ABS there comes the analysis of structural features and forming process of the intelligent ball . This design uses the CAD technology to carry on the mold assembly drawing and the detail drawing plan. Then showing the design analysis of the formation part, the gating system to the mold, lateral to pull out the core organization , promote the mold emptier and cooling system. Including gating system using straight runner point runner, side core-pulling mechanism used inclined guide pin, lateral spreads block to cooperate to complete, roll out using top stem drive demoulding mechanism, cooling systems use roof launch cross network circulation channel, evenly distributed in cavity and cores. Through the analysis about the manufacturability of the plastic molding and the calculation and verification of the main part inside the injection molding machines then complete the assembly drawing design and the mapping of the main components at last. So that we can ensure the reliability,  the rationality and the usability of the mold structure.
