Optimised Design of Mold for Vehicle Throttle Body Bracket Based on CAE
Main Article Content
Abstract
The throttle body bracket is a structure to support and fix the throttle body. Its quality not only affects the performance of the throttle body, but also affects the running performance of car. Excellent mould is important guarantee for quality of the throttle body bracket. In this paper, mould of vehicle throttle body bracket is taken as research object. Methods combining structural design, simulation analysis with optimization design are adopted. First, process and structure of the bracket are analysed. Three plate mould structure and single-impression layout are determined. Based on mould flow optimization analysis, gate type and location are selected, structural dimensions of forming parts are calculated to design the side core pulling mechanism, remoulding mechanism and cooling system. Simulation analysis for filling time, weld line location, cavitation, cooling effect and warpage deformation are carried out by CAE to realise the optimal design of mould for the throttle body bracket.
