PROBLEM TO BE SOLVED: To provide a computer aided mold design device enabled to improve an analysis accuracy of a flow behavior of a resin by accurately determining a completion of a mold clamping.SOLUTION: In a computer aided mold design device provided with a simulation program for analyzing a flow behavior of a resin when the resin charged into a mold is clamped by a compression force F, the compression force F is increased for every predetermined time &Dgr;t until reaching an upper limit value (Fmax, Fs) while a resin 30 is clamped so that its flow behavior (S10 to S20) is analyzed, and when the compression force F reaches the upper limit value, an alternate value Fa of the compression force F is calculated based on a stress relaxation time of the resin (S24, S26). |
