Summary:PROBLEM TO BE SOLVED: To increase yield of a core by inhibiting the core from being broken or scratched, when a slide core is extracted by being retreated from a shape part with a small extraction slope.SOLUTION: When a slide core 4 is extracted by being retreated, the slide core is extracted while displacements of both two regions are adjusted so that a difference between the displacements of the two regions away from each other in a direction orthogonal to an extraction direction of the slide core 4 in a seal plate 8 cannot exceed a predetermined amount. 【課題】抜き勾配の小さい形状部分からスライドコアを後退させて引抜く際に、中子の折れや傷の発生を抑え、中子の歩留まりを向上させる。【解決手段】スライドコア４を後退させて引抜く際に、シールプレート８においてスライドコア４の引抜方向に直交する方向の離れた２つの部位間の移動量の差が所定量を超えないように両部位の移動量を調整しながら引抜くようにする。【選択図】図６
