Thermal analysis of conformal cooling channels in injection moulding
Cooling channel system in injection mould is crucial because it affects the moulded part quality and the rate of the moulding process. This paper presents a study of novel conformal cooling channel designs for injection moulds. Various cooling channel designs including conventional and conformal types are developed and analysed using Pro/Mechanica Thermal simulation software. Various designs and configurations including variation in channel cross section geometry are compared and evaluated in terms of cooling efficiency based on temperature distribution and cooling time using steady state and transient analysis conditions. Results show that the conformal cooling channel system with novel cross section designs obtain shorter cooling time and better temperature distribution in comparison to the conventional cooling channels.
The real-time identification and prediction are the two most important key parts during the intellectualized control of sheet forming.The selection of the input and output parameters for the identification and prediction of the neural network model is vital to the success of intellectualized control and the degree of the control precision.Factors influencing the process of forming and unloading are studied in this paper through finite element numerical simulation of the process of V-shape free bending of wide sheet metal using the software ANSYS.It provides the base for the selection of input and output parameters for the identification and prediction of the neural network model of intellectualized controlling for V-shape free bending of the wide sheet.
