ニター装置。 In a monitor device that uses a load meter to detect the pressing force of the injection plunger of a die-casting machine,
The load meter, an input device for processing the output of the load meter and inputting it to a microcomputer, and receiving the input, P=F/(1/4・π・D 2
) (where F is the pressing force of the injection plunger and D is the tip diameter of the injection plunger).
, Pressure of molten metal for casting (hereinafter referred to as on-metal pressure)
The above-mentioned on-metal pressure P1 when the molten metal has completed filling the cavity of the die-casting mold before the pressure-increasing hydraulic circuit is outputted and the pressure-increasing hydraulic circuit is activated, and the on-metal pressure P2 after the pressure-increasing hydraulic circuit is activated, and between the above-mentioned P1 and P2. The pressure increase time Ts by the pressure increase hydraulic circuit is input as a set value input from the optimum casting conditions of the die casting machine, and the moment when the set value inputs P1 and P2 are exceeded is detected by actual measurement of P, and during that time Measure the actual pressure increase time T, then compare it with the set value input Ts, and if T≦Ts, it is a normal signal, T>T
1. A die-casting machine casting pressure detection monitoring device comprising: a control device having a function of outputting an abnormal signal if s is detected; and a display section for displaying the control output.
