A brake shell high-pressure casting feeding running gate system, comprises nowel, top box and die cavity, and the cross gate of described die cavity arranged outside circular arc type is positioned at the bottom of top box, has ingate to communicate with die cavity; Circular arc cross gate arranges sprue outward, communicate with circular arc cross gate, on described die cavity, feeding head is set, be positioned at lower box part, described feeding head, comprise a riser buss and a cameron core, described cameron core, between riser buss and die cavity, middle part is for cutting off the circular base plate of die cavity and riser buss, in circular base plate, be provided with the molten iron passage that is communicated with die cavity and riser buss inner chamber, the both sides of circular base plate are provided with location core print, and described riser buss Xiang Duan is provided with gas outlet.
Further, described location core print is the location core print of tetragonous cone table shape, and side of tetragonous cone table and the cylindrical of circular base plate are tangent.
Further, described riser buss is heat preservation riser buss.
Further, the maximum outside diameter of described riser buss is 102 ㎜, and effectively modulus is 2.25cm.
Further, described feeding head is four, on the top of the die cavity of annular, along circle, along even circumferential, distributes.
Further, described location core print is divided into the iron wire hook of putting zigzag, and the bottom of location core print is hooked in one end, and one end is fixed in top box sand mold, with firm cameron core, prevents that the rear cameron core of top box reversion from falling in transportation.
Further, the bottom of described sprue arranges filter, is positioned at the top of nowel.
Further, described filter is floamed ceramics filtrating piece.
Further, on the passage between described circular arc cross gate and filter, choked flow face is set.
Brake shell high-pressure casting feeding running gate system of the present utility model, on die cavity, along circumference, four heat preservation riser busses are set, between riser buss and foundry goods die cavity, cameron core is set, inside there are molten iron channel connection riser buss inner chamber and die cavity, riser buss diameter is less than the width of annular die cavity, effectively modulus is large, be conducive to rising head model molding, after cast, riser buss can fully carry out feeding to foundry goods, guarantee the inherent quality of product, and the setting of cameron core is easily cut rising head, provide convenience to the subsequent production of foundry goods.
