Middle groove sand wash preventing firebrick pouring device

Abstract

The invention discloses a pouring device for anti-scour sand refractory bricks in the middle groove, which includes an upper sand box, the upper sand box and the lower sand box cooperate with each other to form a mould, and the upper sand box and the lower sand box are provided with molding sand inside. , both sides of the upper sand box and the lower sand box are fixedly equipped with handles, and a cavity is arranged inside the mold, and the sand core set in the cavity is fixedly installed in the mold, and the molding of the upper sand box There are a plurality of horizontally distributed air holes in the sand, the gate on the upper sand box is set inside the molding sand, the sprue connected under the gate is set in the molding sand, and the sprue bottom is set A buffer fireproof brick is arranged in the sprue groove, and the runner connected to the left side of the sprue is arranged in the molding sand. The invention adopts a simple and practical structural design, which can well reduce the buffer force when molten steel is poured, and can effectively block loose sand grains, thereby improving the quality and processing efficiency of workpieces.

Description

technical field [0001] The invention relates to the technical field of pouring equipment, in particular to a pouring device for anti-scouring refractory bricks in a middle groove. Background technique [0002] At present, with the rapid development of my country's economy, the level of industrial production has also been greatly improved. For some parts with complex structures, they are often not suitable for cutting and processing. They are generally made by pouring molding. The function of the pouring system is to control the filling of molten metal. The speed of the mold and the time required to fill the mold; make the molten metal enter the mold smoothly, avoid turbulence and scour the mold; prevent slag and other inclusions from entering the cavity; do not entrain gas during pouring, And try to make the casting conform to the principle of sequential solidification when cooling, but because the junction of the sprue and the runner is also the formation of the sand mold, th...
