ある。Hereinafter, a method for monitoring injection conditions according to the present invention will be explained in detail. The figure is a block configuration diagram of a monitoring device showing an embodiment of a method for monitoring injection conditions according to the present invention. In the figure, 1 is a sonic wave detection sensor attached to the injection part of the mold 10 or the casting machine 11, that is, the supply passage for molten material filled into the mold cavity or its vicinity, and 2 is this sonic wave detection sensor. Reference numeral 1 is an analyzer that analyzes the signal waveform corresponding to the detected sound waves sent out, 3 is a reference pattern setting unit that stores, as reference sound wave patterns, those that indicate good quality among the detected sound waves analyzed by this analyzer 2, and 4 is a reference pattern setting unit for each shot. a monitor pattern input section which inputs the monitor pattern of the detected sound wave analyzed in the analyzer 2; 5 a comparison calculation section which performs a comparison operation between the reference pattern of the reference pattern setting section 3 and the monitor pattern of the monitor pattern input section 4; A display section 7 inputs and displays the reference pattern and monitor pattern input to the comparison operation section 5 in a branched manner, and an output section 7 processes the calculation result in the comparison operation section 5 as an output signal.

Both have become a pattern. In the reference pattern setting unit 3, the sonic wave pattern when a test result of each casting (molding) item (for each mold) indicates a good product is stored as the transition of the reference pattern. . Further, a CRT device, for example, is used as the display section 6, and the comparison calculation results from the comparison calculation section 5 are also displayed on the display section 6.

同時に表示部６において異常の表示がなされる。Next, the operation of the monitor device configured as described above will be explained. That is, first, a reference pattern is input to the reference pattern setting section 3. If this standard pattern is set in advance, it can be freely set for each mold using an external operation key (not shown). The reference pattern selected and set by this external operation key is also displayed on the display section 6. When a shot is started in such a state, the monitor pattern for that shot is input to the monitor pattern input section 4 and displayed on the display section 6 at the same time. At the same time, the information on the reference pattern and the information on the monitor pattern are compared and calculated in the comparison calculation section 5 and input in advance (
A comparison is made with a permissible value (which has been set), and if it is determined that the value is equal to or higher than the permissible value, an abnormality signal is output to the output section 7 and at the same time an abnormality is displayed on the display section 6.
