Optimised Design of Mold for Vehicle Throttle Body Bracket Based on CAE

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.

The mould for production of plastic spout cap with internal thread by injection moulding

The main aim of this article is the mould design for production of plastic spout cap with inner thread by injection moulding technology. There are described the basic steps of whole design process with respect to fulfil all technology and functionality requirements. The application of hot runner system as well as hybrid ejection system based on rotary cores and stripper plate can be considered as the main innovative features of the designed mould. The mould flow analysis was carried out for the functionality demonstration.

The Mould Design for Production of Plastic Component by Injection Moulding Technology

The article deals with the design of the mould for plastic component production by injection moulding technology. There are described the basic steps of whole design process how to choose and design the suitable components with respect to fulfilling the technology requirements necessary for high quality products. The mould contains also the rotary cores with respect to the shape and dimensions of produced part, especially the thread surfaces. The mould flow analysis was carried out for the functionality demonstration.
