This invention relates to a casting control system of a die cast machine, and more particularly to a system for controlling a high speed injection real stroke of an injection plunger and controlling valve closing timing for degassing gas in a mold cavity. The high speed injection real stroke is searched in response to a signal delivered from a position detector by an arithmetic unit and compared with a certain preset value. When the high speed injection real stroke and the preset value do not coincide with each other in a process of the arithmetic unit, a value set as an action delay time of the injection plunger is ? corrected step by step until the both values coincide with each other. The arithmetic unit searches a start position of the high speed injection real stroke, outputs a signal to close a breathing valve at a position, to which is added or from which is subtracted a predetermined variable value with respect to the real start position and outputs a signal to open the breathing valve at a position where the injection plunger closes a molten metal feeding port.
