A kind of mould structure for the production of the automobile-used flange forge piece of heavy construction of the utility model, it comprises core roller and main mould, forging is arranged between described core roller and described main mould, described core roller middle part is the cylindrical section of cylindrical structure, on described cylindrical section, be provided with convex shoulder, the upper surface of described convex shoulder is downward-sloping, and the lower surface of described convex shoulder is inclined upwardly; The side of described convex shoulder comprises the first rake and the second rake from top to bottom, and described the first rake is outward-dipping from top to bottom, and described the second rake slopes inwardly from top to bottom; Described main mould is provided with vertically section of the first vertical section, the first slope section, the second slope section and second with this from top to bottom.
Further, the angle between the described first vertical section and the first slope section is between 130 °～140 °.
Further, the angle between described the first slope section and the second slope section is between 135 °～150 °.
Further, downward-sloping 18 °～22 ° of the upper surface of described convex shoulder, and the joint of described upper surface and the cylindrical section circular arc that is R10.
Further, the lower surface of described convex shoulder is inclined upwardly 42 °～48 °, and the joint of described lower surface and the cylindrical section circular arc that is R10.
Further, the angle of described the first rake and vertical direction is 1 °～5 °, and the angle of described the second rake and vertical direction is 28 °～32 °.
Further, the circular arc that the joint of described the first rake and described upper surface is R25, the circular arc that the joint of described the second rake and described lower surface is R50.
The beneficial effect that the utility model reaches is:
The automobile-used flange forge piece of heavy construction that the Mould Machining providing by the utility model goes out, more approach the shape of product, saved the use of material, than conventional rectangle forging, save raw material approximately 20～30%, than single, have external diameter or internal diameter to have shape conservation 15% left and right, the cutting output of following process is little, properties of product are better, processing cost is low, and mould is that forging process leaves certain calendering space simultaneously, has guaranteed the quality and performance of product.
