| 摘要 | PURPOSE:To provide a titled device which can measure an adequate max. injection speed with simple constitution, by constituting the same in such a way that the moving stage of an injection mechanism is detected by a pulse sensor, and the data on the period of the entire pulse detected and stored at prescribed timings is operated and collated in the ending stage of injection. CONSTITUTION:The signal obtained with a pulse sensor 10 disposed in an injection mechanism of a die casting machine is supplied to a detecting circuit 12 for pulse periods. The circuit 12 detects the pulse periods of the pulse signal digitally with a clock generator 20 provided therein. The data on the pulse periods detected with the circuit 12 with time is stored successively with a storage circuit 14 for pulse periods. On the other hand, when an arithmetic circuit 16 judges the starting state of injection from the external signal, the circuit controls the injection speed by storing the data on the pulse periods detected with time from the circuit 12 successively with the circuit 14. When the circuit 16 judges the ending state of injection from the external signal thereafter, the circuit processes the data on the pulse periods stored with the circuit 14 and calculates the max. injection speed. | ||||||
