Abstract
PURPOSE: To prevent temperature drop of molten metal without enclosedly pressing the molten metal and improve the degree of its penetration into the cavity by lowering a plunger tip and a counter tip at the same speed.
CONSTITUTION: When molten metal 37 is poured through a pouring port 13 into a sleeve 11, the molten metal 37 is temporarily stored on a counter tip 15. Next, an electromagnetic change over valve 25 is changed over to the mode (a) by the signal to a control unit 26 and a pump 24 is started. A piston 20 descends and a plunger 14 descends until it goes down to the position reaching the top surface of the molten metal, then the signal from a limit switch 33 changes over an electromagnetic change over valve 32 to the mode (b) and causes a pump 31 to run, thereby causing the piston 27 and counter tip 15 to descend. The flow rates of the oil to be injected into hydraulic cylinders 17, 19 are controlled just the same and the plunger tip 14 and counter tip 15 descend at the same speed. When the top face of the counter tip 15 reaches the bottom edge of a cavity sprue 12, the descending of the counter tip 15 is stopped by the signal of a limit switch 34. Thereupon, the molten metal 37 is extruded into the cavity 10 by the tip 14.
