Drinking Water Box Mould Design Of NC Machining And Finite Element Analysis

Since the reform and opening up to the high speed development, mould industry of injection mold design and manufacturing put forward higher request. With good quality and high precision, research and manufacturing cycle is short, is now the basic requirements of processing industry. In order to meet the requirements of the professional mould industry, each big software company in the new characteristics of mould launched operation simple, functional perfect CAD/CAE/CAM special die system. If the company, according to U.S. UGS injection Mold design launched Mold injection molding design guide wizard module. This module good integrated in CAD/CAE/CAM machine system, for each user manufacturer provides injection mold design environments and tools, and provides all kinds of standardization of formwork, libraries and embeded parts, the mould design and packaging expert knowledge. And support for molding process of CAE simulation, and has obtained the certain technical and economic benefits, promote and our mould CAD/CAE/CAM technology development. The user can achieve using UG software can be achieved from design to the injection molding process of nc forming, injection mould design and machining process of 3D virtualization, which greatly reduces the mould design and manufacture of the cycle, notable economic benefit obtained.Based on the analysis of domestic CAD/CAE/CAM integration research situation, proposed based on UG drinking water box mould design of nc machining and finite element analysis of research. This paper has three aspects: first is the Mold design, at this stage is mainly using UG Mold wizard module water box mould design, Mold design and the deficiency in real-time, eliminating the traditional mould repairing Mold design of production process, shorten the cycle of mould. The second is the water box mould of nc machining, at this stage of the process of mould processing, chose reasonable cutting strategy and technology, puts forward the optimal processing parameters. To improve the workpiece machining quality, shorten the processing time, Using the CAM module CNC programming, optimizing processing route, the tool path of process parameters, and finally got the N.C. program, the optimal process. Complete the die. The third is the ANSYS finite element analysis software docking water box mould made by static analysis, the results of static analysis of mould stress concentration or stress of two times the extrusion of fatigue analysis, finally calculated the mould allows the fatigue life cycle and fatigue coefficient.
