<P>PROBLEM TO BE SOLVED: To form a metal mold in a short time while prospecting a springback in press work of a steel plate and a warp in injection molding of resin. <P>SOLUTION: A prospect model generation device for metal mold includes input means (14) of accepting input data; an analytic model generation part (102) which generates an analytic model before deformation which consists of a plurality of microelements and nodes corresponding to a surface shape of a metal mold; a solver part (104) which generates an analytic model after deformation which has been taken out of the metal mold by performing deformation analysis based upon the analytic model and conditions; an inversion vector generation part (110) which finds a displacement vector based upon the analytic model after deformation, and inverts it to obtain an inversion vector; a prospect vector generation part (112) which alters the inversion vector; and generation processing parts (114, 116) for prospect analytic model or prospect curved surface which compute a prospect analytic model or prospect curved surface to obtain prospect shape data on the metal mold. <P>COPYRIGHT: (C)2012,JPO&INPIT |
