Abstract: Surface 27 of molten metal within a mold is constantly monitored by camera 25. Camera 25 records the surface from an obliquely upward position of the mold in an area that does not affect the casting process. Various analyzing frames such as analysis band 35, molten metal pattern 37, and injection monitoring part 43, are set with respect to the information recorded by the camera 25. The analysis band 35 includes the surface (molten metal part 31c), and is set to a predetermined width so that the direction of surface change is in the longitudinal direction. The width of the analysis band 35 is set as wide as possible in a range that does not block the discharge part (molten metal part 31a). Inside the analysis band 35, the rate of change of the binary data is calculated by the analyzing part.

Abstract translation: 模具内的熔融金属表面27由照相机25持续监控。相机25将表面从模具的倾斜向上的位置记录在不影响铸造过程的区域中。 关于由照相机25记录的信息，设定分析带35，熔融金属图案37，注射监测部43等各种分析框。分析带35包括表面（熔融金属部31c），并设定 达到预定宽度，使得表面变化的方向在纵向方向上。 在不阻止排出部（熔融金属部31a）的范围内，将分析带35的宽度设定得尽可能宽。 在分析带35内，通过分析部分计算二进制数据的变化率。
