Abstract
(EN) A fixation-side mold plate (52) is provided with a sprue bush (53) in which a sprue (54) for introducing a molten resin is formed. One end of a sensor (14) that measures a state of the resin immediately after flowing into the sprue (54) is inserted into the sprue bush (53). At a part of the sprue (54), a detection sprue (56) having a flat surface that becomes flush with a tip end surface of the inserted sensor (14) is formed.
(FR) Une plaque de moule côté fixation (52) est pourvue d'une buse de carotte (53) dans laquelle une carotte (54) pour introduire une résine fondue est formée. Une extrémité d'un capteur (14) qui mesure un état de la résine immédiatement après l'écoulement dans la carotte (54) est insérée dans la buse de carotte (53). Au niveau d'une partie de la carotte (54), une carotte de détection (56) ayant une surface plate qui vient en affleurement avec une surface d'extrémité de pointe du capteur inséré (14) est formée.
(JA) 固定側型板（５２）には溶融樹脂を導入するスプルー（５４）が形成されたスプルーブシュ（５３）が設けられており、スプルーブシュ（５３）には、スプルー（５４）に流入した直後の樹脂状態を計測するセンサ（１４）の一端が挿着され、かつ、スプルー（５４）の一部には、挿着されたセンサ（１４）の先端面と面一となる平坦面を有する検出用スプルー（５６）が形成されている。
