针对于压铸机，模内监控主要起到的作用在于闭模前，是否有产品残留等情况进行检测，由于压铸机现场会有高温和水汽情况，所以一般装机时需要对相机和连接线做特殊保护。

For the die casting machine, the mold monitor is to detect whether there is any product residue before closing the die. As there will be high temperature and water vapor at the die casting machine site, special protection shall be provided for the camera and connecting wire during general installation
