    • Provided are a resin molding device and a resin molding method for easily removing a thin and soft resin molded product from a mold with a good finish by sensing an operation failure of an air ejector reliably. An air ejector (22) of a resin molding device (20) comprises air passages (24a, 24b), air outlets (26a, 26b) through which air is injected, movable valves (27a, 27b) biased by bias members (29a, 29b) to close the air outlets (26a, 26b), accommodation spaces (28a, 28b) in which the movable valves (27a, 27b) are movably contained, an air supply path (32) through which air is supplied from an air supply source (33), and a pressure sensor (35) to detect air pressure. After completing the mold removal, the air is supplied via the air supply path to the air passages at an air pressure smaller than the bias force of the bias members, and the air pressure is detected by the pressure sensor.
    • 本发明提供一种树脂成形装置和树脂成形方法,通过可靠地检测空气喷射器的动作不良,能够容易地从表面良好的模具中将薄且柔软的树脂成形体除去。 树脂成形装置20的空气喷射器22由空气通路24a,24b,注入空气的空气出口26a,26b,由偏置构件29a,29b偏置的可动阀27a, (26a,26b)关闭空气出口(26a,29b),可移动地容纳可移动阀(27a,27b)的容纳空间(28a,28b),空气供应通道(32) 源(33)和检测气压的压力传感器(35)。 在完成模具移除之后,空气通过空气供应路径以小于偏置构件的偏置力的空气压力供应到空气通道,并且空气压力由压力传感器检测。
