Specific embodiment
All features disclosed in this specification can be with any other than mutually exclusive feature and/or step
Mode combines.
Embodiment one
Shown in the present embodiment combination Fig. 1, Fig. 2 and Fig. 3, a kind of mold core processing tool, including copper rod 4 and extrusion mold core 9, institute
It states copper rod 4 and is provided with inner hole, the extrusion mold core 9 is assemblied in inner hole, squeezes out the feed set 8 that mold core 9 includes concentric truncated cone-shaped
The sizing straight tube 10 formed with 8 top surface of feed set along 8 axis direction outwardly convex of feed set, the copper rod 4 are cylindrical structure,
The inner hole include be separately positioned on 4 both ends end face center of copper rod inwardly along 4 axis direction of copper rod be recessed the inner hole a2 to be formed and
Inner hole b6, the inner hole a2 include in the exit orifice a1 and cylindrical structure of the concentric circular platform type structure set gradually from outside to inside
The section internal diameter ecto-entad of hole a3, the exit orifice a1 successively successively decrease, and the angle of the axis of the bus of exit orifice a1 and copper rod 4
Be 17.5 °, the section internal diameter of the inner hole a3 is equal with the smallest cross-sectional internal diameter of exit orifice a1, and in the section internal diameter of hole a3 be greater than
Or the outer diameter equal to sizing straight tube 10；
The inner hole b6 includes the exit orifice b7 and cylindrical structure of the concentric circular platform type structure set gradually from outside to inside
In hole b5, the section internal diameter ecto-entad of the exit orifice b7 successively successively decreases, and the angle of the axis of the bus of exit orifice b7 and copper rod 4
Be 30 °, the section internal diameter of the inner hole b5 is equal with the smallest cross-sectional internal diameter of exit orifice b7, and in hole b5 section internal diameter be greater than or
Equal to the outer diameter of sizing straight tube 10；
The depth of the inner hole a2 is greater than the total length of the extrusion mold core 9 matched with inner hole a2 in the axial direction, inner hole
The depth of b6 is greater than the total length of the extrusion mold core 9 matched with inner hole b6 in the axial direction.
In use, corresponding extrusion mold core 9 is assembled in inner hole a2, by the outer wall of passage with exit orifice a1's
Inner wall is bonded completely, and inner hole a2 is directed at cross-head and is promoted, and in being inserted into cardan shaft in the b5 of hole, and passes through cardan shaft pair
Copper rod 4 starts thrust, will be squeezed out in 9 loading unit of mold core by 4 transmission force of copper rod.
Existing extrusion mold core 9 be usually 35 ° of mold cores and 60 ° of mold cores, it is right by squeezing out the shape angle of mold core 9 now
Original copper rod 4 is redesigned, and multiple inner holes is arranged, and inner hole is divided into two sections, one section is put into mold core head just
In corresponding inner hole, intermediate fitting completely increases and squeezes out when mold core 9 is installed with 4 matching of copper rod, reduce and squeeze out without gap
