摘要： An abnormal mold detector is provided that can previously detect the breakage of a mold tool with an ejector plate. A pressure sensor is attached to the ejector pin of a mold to detect the mold internal pressure. The operation status of the mold is detected by the sensor attached to the mold piece of the mold. An abnormality detector, formed of a CPU, processes the detected pressure signal and the mold working state indicating signal. The abnormality detector sets a reference value D exceeding a normal sticking resistance of the ejector pin. As a material is injected, the mold internal pressure increases during one cycle (A and B) in the molding step. After the molding process, the ejection process is carried out by the ejector pin during the value C. When a sticking resistance exceeding the value D is confirmed during the monitoring operation (FF), the abnormality detector decides that there may be the possibility that an abnormal state occurs in the mold tool. Thus the abnormality detector issues an alarm signal to the operator to halt the operation of the molding machine.
