Abstract
PURPOSE:To eliminate the temp. difference in a fixed die and movable die and to discharge the air inside the movable die at the molten metal filling time by constituting by a horizontal die clamping type die opening and closing device and a holding furnace for low pressure casting installed under the die mating position in the same main body. CONSTITUTION:When the air valve 8a of a pressurizing pipe 8 is opened and the inside of the holding furnace A2 for low pressure casting is pressurized after die closing, the molten metal inside the furnace A2 is extruded, raised inside a, stoke 9 and filled up into a cavity a1 from sprues a1', a2'. At this time, the molten metal is filled up in order towards the upper side from the bottom face a1', a2' of a cavity a3 and the air inside the cavity a3 is exhausted in all from the air vent of the die mating face upper part. Due to the holding furnace A2 being installed under the die mating position the molten metal filled up in the cavity a3 is solidified from the above part to the lower part. The molten metal inside the cavity a3 is pressurized until the solidification is completed by receiving the pressure of the molten metal press-fitted from the sprues a1', a2' during the solidification and the generation of a shrinkage cavity is prevented.
