Zusammenfassung:To allow a cooling circuit to be readily configured in such a way that a distance from a mold surface to the cooling circuit at the inside is kept constant when designing the cooling circuit of a mold.SOLUTION: A method of designing a cooling circuit in a mold that includes therein the cooling circuit that passes through an inlet and an outlet includes a control plane setting step, a reference plane setting step, an intersection line extraction step, and a circuit setting step. The control plane setting step sets a control plane that is perpendicular to the mold surface on the side which comes in contact with a material and that passes through the inlet and the outlet. The reference plane setting step sets a reference plane that is offset by a fixed distance from the mold surface to the inner side. In the intersection line extraction step, an intersection line at which the control plane and the reference plane intersect is extracted. In the circuit setting step, the cooling circuit is set inside the mold along the intersection line.SELECTED DRAWING: Figure 2 【課題】金型の冷却回路を設計するに際し、金型表面から内部の冷却回路までの距離を一定に保つように容易に冷却回路の設定を行うことを可能にする。【解決手段】入口と出口とを通過する冷却回路を内部に有する金型における冷却回路を設計する方法は、制御面設定ステップ、基準面設定ステップ、交差線抽出ステップ、及び回路設定ステップを備える。上記制御面設定ステップは、材料と接する側となる金型表面に垂直で、且つ入口と出口とを通過する制御面を設定する。上記基準面設定ステップは、金型表面から内部側に一定距離オフセットした基準面を設定する。上記交差線抽出ステップは、制御面と基準面とが交差する交差線を抽出する。上記回路設定ステップは、交差線に沿って金型の内部に冷却回路を設定する。【選択図】図2
