Abstract
PURPOSE: To prevent the formation of casting defects through applying proper injection speed and pressure to molten metal by installing a pressure control valve operated by a control device to an injection cylinder provided with a variable displacement type pump, in high-pressure casting of molten metal.
CONSTITUTION: A variable displacement type pump 5 is connected via a changeover valve 6 to an injection cylinder 1 having an injection plunger 2 which injects molten metal under high pressure into dies. Also, a pressure control valve 9 and a control device 4 such as computer are installed. The pump 5 is driven to supply pressurized oil via the vlave 6 into the cylinder 1, which in turn pushes out the plunger 2, thereby forcing the molten metal under high pressure into the dies. The injection position of the plunger 2 is detected at this time with a position detector 3, and the optimum injection pressure and speed are operated by the signal B thereof and casting set condition signal A in the control device 4. The operated values C, D are inputted to the valve 9 and the pump 5, whereby both are controlled so that the plunger 2 is controlled always to the proper injection speed and pressure.
