Embodiment Construction
[0014] Below in conjunction with accompanying drawing, the present invention will be further described, as appended figure 1 , figure 2 As shown, firstly, the clay sand mold 3 with a size of 1200mm×1200mm and the coated sand mold 1 with a size of 1200mm×1200mm are arranged alternately and orderly, placed on the platform, and the mold cavity 4 is obtained after the mold is closed. Then cover the iron plate 6 on both sides and the facade of the sand mold to fix it, changing from "without box" operation to "with box" operation. The upper part of the cavity 4 is provided with gates 2, and each gate 2 is connected with the pouring machine, and molten iron is poured into all the cavities 4 at the same time. According to the demand of the manhole cover, determine the pouring speed, and incubate with the flow until the cavity 4 is filled. Repeat the above pouring procedure until all the cavities 4 are poured. After cooling, take out the manhole cover from the sand mold, process th...
