Detailed Description

In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.

Refer to fig. 1 to 3

A steel slag basin forming die adopting a foam die comprises a sand box 10, wherein a steel slag basin die cavity 12 formed after filling and molding through molding sand 11 is arranged in the sand box, and a pair of first trunnion dies 20 made of foam are respectively embedded in two sides of the lower part of the steel slag basin die cavity, so that the first trunnion dies are filled with molten steel into a pair of first trunnions after being melted. Second trunnion moulds 30 made of foam are pre-embedded in the middle parts of the two sides of the upper part of the slag basin cavity respectively, so that the second trunnion moulds are filled with molten steel into second trunnions after being melted. The upper part of the molding sand is provided with a pouring gate 13 connected with the steel slag basin-shaped cavity, and the upper side of a pouring cup of the pouring gate is provided with a drainage sand and steel water separation mechanism.

In this embodiment, for better molding of molding sand, the flask includes several vertically through baskets 14 stacked in sequence from bottom to top, and hanging shafts 15 are fixed to two sides and front and rear sides of the baskets respectively, so as to facilitate the hoisting of the baskets. The periphery of the basket plate is provided with a reinforcing convex rib, thereby improving the strength of the basket plate.

In this embodiment, in order to form the first trunnion 3 and the second trunnion 4 of the slag pan better, the connecting end of the first trunnion mold and the second trunnion mold respectively stretches into the slag pan cavity and the inner wall of the slag pan cavity is tightly attached to the inner end of the inner side of the first trunnion mold and the second trunnion mold, the outer side portions of the first trunnion mold and the second trunnion mold are provided with the shaft portion 21, and the outer end portions of the first trunnion mold and the second trunnion mold are provided with the annular flange 22, so that the slag pan is formed to be hoisted and the like through the first trunnion and the second trunnion.
