Abstract: A method for controlling the injection of a die casting machine in which immediately after molten metal is injected into a cavity of metal molds at a high speed, the pressure oil in the chamber at the rod side of an injection cylinder is discharged into a tank side to commence the increase in pressure. A reference point for a switching-over position where a high speed charge is switched over to the increase in pressure is determined by computing a necessary length along the path for keeping the increased charging pressure on the basis of the supplied molten metal quantity during the previous injection process and subtracting the length from the length between the starting position and the position of limit of the forward movement at the previous injection process.
