Abstract
The utility model discloses a knuckle preforging die structure which comprises an upper die and a lower die. A die core is arranged in the middle of the upper die and a die cavity is arranged in the middle of the lower die, wherein the die core is mutually and correspondingly fastened with the die cavity. The knuckle preforging die structure is characterized in that an annular boss is arranged on the lower die outside the die cavity. An annular groove which matches with the annular boss in a gapped mode is arranged in the upper die outside the die core. A gap is formed between the die core and matching face of the die cavity. The knuckle preforging die structure has the advantages of being reasonable in structure and design, capable of increasing the height of a material blocking wall, reducing an inclined angle of the material blocking wall and simultaneously reducing a gap between the upper die and the lower die, good in effect of material blocking, capable of well preventing materials from flowing outside the die cavity, thereby effectively improving utilization rate of the materials and reducing cost.
Description
Technical field
The utility model relates to the forging die field, relates in particular to a kind of knuckle Preform Die structure.
Background technology
In the existing knuckle Preform Die, the Preform Die structural design is simple, and the height of its resistance material wall is shorter, the angle of inclination of resistance material wall is larger, and the gap between the upper and lower mould is larger simultaneously, thereby the resistance material effect is bad, stock utilization is low, and cost is high, can not satisfy instructions for use.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of knuckle Preform Die structure is provided, it is simple to have solved existing Preform Die structural design, the height of its resistance material wall is shorter, the angle of inclination of resistance material wall is larger, and the gap between the upper and lower mould is larger simultaneously, thereby the resistance material effect is bad, stock utilization is low, the high in cost of production problem.
The utility model is achieved through the following technical solutions:
A kind of knuckle Preform Die structure, include upper die and lower die, the middle part of described upper die and lower die is respectively equipped with mutual corresponding core rod and the die cavity that fastens, it is characterized in that: the outer counterdie of described die cavity is provided with annular boss, the outer patrix of described core rod is provided with the annular groove with the annular boss matched in clearance, also leaves the gap between described core rod and the die cavity mating surface.
The bottom face of described core rod and the angle between the lateral surface are 90 °, are parallel to each other between the madial wall of described annular boss and the lateral wall of core rod.
Gap between the bottom land of described annular groove and the upper surface of annular boss is between the 1mm-3mm, and the gap between described core rod and the die cavity mating surface is between the 0.5mm-1mm.
Its principle is: by the design of the annular boss between the upper die and lower die and annular groove, increased the height of resistance material wall, the angle of inclination of having reduced the resistance material wall is almost 0, reduced simultaneously the gap between the upper and lower mould, resistance material is effective, can well stop material outside die cavity, to flow, thereby can effectively improve stock utilization, reduce cost.
The utility model has the advantages that:
The utility model reasonable in design has increased the height of resistance material wall, the angle of inclination of having reduced the resistance material wall, reduced simultaneously the gap between the upper and lower mould, resistance material is effective, can well stop material to flow outside die cavity, thereby can effectively improve stock utilization, reduce cost.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, a kind of knuckle Preform Die structure, include patrix 1 and counterdie 2, the middle part of patrix 1 and counterdie 2 is respectively equipped with mutual corresponding core rod 4 and the die cavity 3 that fastens, die cavity 3 outer counterdies are provided with annular boss 5, core rod 4 outer patrixes are provided with the annular groove 6 with annular boss 5 matched in clearance, also leave the gap between core rod 4 and die cavity 3 mating surfaces; The bottom face of core rod 4 and the angle between the lateral surface are 90 °, are parallel to each other between the lateral wall of the madial wall of annular boss 5 and core rod 4; Gap between the upper surface of the bottom land of annular groove 6 and annular boss 5 is between the 1mm-3mm, and the gap between core rod 4 and die cavity 3 mating surfaces is between the 0.5mm-1mm.
