The phenomenon that, lead to scrapping for mold.
Utility model content
The main purpose of the utility model is to provide a kind of wire-drawing mold core of anti-dropout and molds, solve wire-drawing die and exist
The phenomenon that mold core falls off out of sintered body during production.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: wire-drawing mold core of anti-dropout,
Mold core material is one of diamond, artificial diamond, PCD diamond, CVD single-crystal diamond or polycrystalline diamond, mold core outer wall
Equipped with groove.
In preferred embodiment, groove is the vertical slots of axis direction, is perhaps helicla flute or is annular groove.
In preferred embodiment, trench cross section shape is rectangular, triangle, trapezoidal or semicircle.
In preferred embodiment, the outer wall of mold core is tilted, and die sleeve Way in is relatively large in diameter, die sleeve export direction diameter compared with
It is small.
In preferred embodiment, groove number is 1 to multiple, and the ratio between trench depth and radius are 1 ~ 10:20.
In preferred embodiment, a kind of wire-drawing die of anti-dropout, die sleeve is interior to be equipped with mold core, and powder is filled between mold core and die sleeve
Powder sintered compact, in the middle part of mold core, sintered powder and die sleeve be equipped with perforation wire drawing mouth, mold core material be diamond, artificial diamond,
One of PCD diamond, CVD single-crystal diamond or polycrystalline diamond, mold core outer wall are equipped with groove.
In preferred embodiment, groove is the vertical slots of axis direction, is perhaps helicla flute or is annular groove.
In preferred embodiment, trench cross section shape is rectangular, triangle, trapezoidal or semicircle.
In preferred embodiment, the outer wall of mold core is tilted, and die sleeve Way in is relatively large in diameter, die sleeve export direction diameter compared with
