The optimal position for the injection gate of a die-casting die

This study explores a computer integrated system application in the design of a die-casting mold, in order to enable accurate and fast determination of the optimal position for the material injection gate. Finite elements are used to find the deformation of various sizes of thin shell piece, after which a deformation learning prediction is made with an adductive network. A simulation annealing (SA) optimization algorithm with a performance index is then applied to the neural network in order to search for the optimal position of the injection gate, with quite satisfactory results being obtained. The system is capable of being applied on the die, in order to reduce wastage on the cost trials of the die. (C) 1999 Elsevier Science S.A. All rights reserved.
