Title: INJECTION MOULDING DIE AND ONLINE QUALITY DETECTION METHOD THEREOF
Abstract:
An injection moulding die and an online quality detection method thereof, the injection moulding die comprising: a fixed die plate (100), a moving die plate (200), a die cavity (300), and an in-die online quality sensing device (400), the in-die online quality sensing device (400) comprising: a sensing device body (1), an insulating layer being provided on all of the surface thereof apart from the contact surface with the die cavity (300), and being used for forming with a fixed die core (110) the two electrodes of a detection capacitor; a connecting wire (2), one end thereof being connected to the sensing device body (1), and the other end being connected to a power source and being used for charging the detection capacitor, or the other end being connected to a computer and being used for transmitting to the computer a voltage signal of the detection capacitor during the entire injection moulding period. By means of detecting the voltage signal during the entire injection moulding period, the injection moulding die can promptly acquire at least one of the injection moulding speed, the injection moulding weight, the injection moulding curing rate, and the injection moulding shrinkage rate inside the die cavity during the injection moulding period; thus, the monitoring content is rich.
