Abstract

PURPOSE:The title device designed to designed to detect the mold champing force and the amount of mold opening with certainty at a position near the filling part and to give a molded article having improved dimensional accuracy and quality, comprising the same detector to determine both the force and the amount. CONSTITUTION:The distance-electricity transducer 9 placed in one contact surface of core and cavity plates is pressed by the protrusion on the other surface upon approach of the plates. The conresponding electrical signal is output to the memory and arithmetic circuits 15 and 16. The circuit 16 calculates the difference between the signals from the circuit 15 and the amplifier 12, and outputs the signal to the memory and the arithmetic circuits 18 and 19. The circuit 18 memorizes the electrical signal (X2-X1) upon completion of mold closing. When the molds are opened upon resin filling, the displacement (X3-X4) of the mold is detected by the transducer 9 continuously and input to the circuit 19 via the circuit 16. The amount of mold opening is calculated by the circuit 19 and output to the control circuit 22.
