<p>A defective molding detecting device for a plastics injection molding machine, wherein at least two desirable points are present on the injection stroke of a plunger in the injection molding machine, the times during which the plunger passes through the respective points are measured, and a defective molding signal is sent out when the measured times deviate from the time allowances preset for the respective points. It is planned that said defective molding detecting device is used together with an off-temperature detecting device wherein the temperature at a desired preset point during molding cycle is measured and an off-temperature signal is sent out when said temperature measured deviates from the preset limit.</p> |
