Abstract
The utility model discloses a square die base, which is provided with square through holes along the radial direction. The square die base is characterized in that the square through holes are set as arc-shaped corner angles at four corner angles on the bottom end part of the base, wherein the arc-shaped corner angles are respectively outwards arranged from four square vertexes by the square through holes. In the square die base, the intensively-stressed part of the base is designed into the circular arc-shaped corner angles to prevent the base from being intensively stressed; the support force of the base is effectively dispersed by the circular arc-shaped corner angles, the phenomenon that the die base cracks because the support stress of the die base can not be dispersed in the pressing engineering can be avoided, and the service life of the square die can be effectively prolonged.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of square dies base with circular arc corner angle.
Background technology
Along with the maturation development of PM technique, various types of magnetic products arise at the historic moment, and the productivity of square product promotes very big, want anxious but thing followed problem die life becomes working as of each big powder metallurgy industry.Mold and punching head comprises support parts such as effective end face part and base, and common square dies is when compacting, base support strength is disperseed by four corner angle of inside respectively, too concentrated because of the support force direction, very easily cause base to ftracture, shortened the service life of mould.
Summary of the invention
Technical purpose of the present utility model is the defective that overcomes prior art, and a kind of mold base sturdy and durable, not easy to crack is provided.
The technical solution of the utility model is a kind of square dies base, radially is provided with square through hole, it is characterized in that: described square through hole is set to the arc corner angle at four corner angle of base bottom part.
Described arc corner angle are the arc corner angle that described square through hole is outwards offered respectively from four square summits.
Described arc corner angle are for being that the center of circle, radian are the arc corner angle of 3/4ths circumference with square summit.
The utility model is by being designed to the circular arc corner angle with the stressed concentrated position of base, avoid stress too concentrated, the support force that has disperseed base effectively, stopped that mold base has effectively promoted the life-span of square dies because of the situation that bearing stress can't disperse to cause the mold base cracking to take place in the compacting engineering.

The specific embodiment
In order to make technical purpose of the present utility model and technical scheme be easier to understand, the utility model is further introduced below in conjunction with drawings and the specific embodiments.
Fig. 1 is the stress force structure schematic diagram of existing mold base, and as shown in the figure, four summits of square through hole are stress point, and dotted portion is base position easy to crack.
Fig. 2 is a structural representation of the present utility model to Fig. 5, a kind of square dies base, radially be provided with the square through hole that is used to install drift, described square through hole four ribs of base bottom part 1 to outside (being the base body) offer respectively one with square summit be the center of circle, radian be 3/4ths circumference arc corner angle 2(as shown in Figure 4), this great circle camber corner angle, the stress that effectively corner angle is subjected to disperses, and has avoided the cracking of mould.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
Claims (3)
