Embodiment Construction
[0018] see figure 1 As shown, the mold shell used in the present invention is a composite ceramic type, the mold cavity is formed by the ceramic type 5, the back cover is a water glass sand cover 4, the upper box 2 and the lower box 1 are combined to form a mold, and the upper box 1 is provided with a pouring mold. Road 8, the heat-resistant protective cover 3 is set outside the mold, and a vent hole 6 is opened above it. One end of the vacuum hose 9 is connected to the water glass sand sleeve 4 from the bottom, and the other end is communicated with the gas source through the flow meter 10 and the valve 11. , the concrete steps of the method of the present embodiment are as follows:
[0019] 1. After the composite ceramic mold is taken out of the 350°C roasting furnace, natural gas is introduced from the bottom into the mold shell through the vacuum hose 9 to drive away the air in the mold shell and cavity and occupy the entire space of the mold shell and cavity When pouring...
