における給湯量制御機構。[Scope of Claim for Utility Model Registration] (1) In a die casting machine that pours molten metal stored in a molten metal insulating furnace into a cavity through a hot water supply pipe under the pressing action of a plunger, one end side of the hot water supply pipe is While communicating with the molten metal heat retention furnace,
The other end side of the hot water supply pipe is connected to the cavity side, and the molten metal passes through the hot water supply pipe at a position on the other end side that is higher than the level of the molten metal in the molten metal heat retention furnace. A molten metal detection means is disposed to detect the passage of the molten metal, and the plunger is further displaced by a predetermined stroke from the time when the passage of the molten metal is detected by the molten metal detection means to supply a predetermined amount of molten metal into the cavity. A hot water supply amount control mechanism for a die-casting machine characterized by: (2) In the mechanism set forth in claim 1 of the utility model registration claim, the stroke of the plunger is determined by the displacement amount that the plunger moves from the time when the passage of the molten metal is detected by the displacement detection means. A hot water supply amount control mechanism in a die-casting machine that detects pulse signals. (3) Utility Model Registration In the mechanism set forth in Claim 1, the stroke of the plunger is determined as the travel time of the plunger by a time detection means that counts time from the time when the passage of the molten metal is detected by the molten metal detection means. A hot water supply amount control mechanism in a die-casting machine that uses detection.
