Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, the utility model provides a kind of punch-forming mold of metallic sintered products, including flanging Circle 1 and the upper mold cover die 2 on blank holder inner wall, the upper surface of the blank holder 1 are installed with moved cross beam 3, Cylinder connector 4 is inlaid on the inner wall of the moved cross beam 3, the lower end of the cylinder connector 4 is fixed by trip bolt Pressing plate 5 is installed, the pressing plate 5 is fixedly mounted on the inner wall of blank holder 1, and the lower end of the cylinder connector 4 passes through bolt It axially is connected with upper mold mandrel 6, the upper mold mandrel 6 is axially disposed on the inner wall of upper mold cover die 2, the upper mold mandrel 6 Upper end is provided with shot 15, and the front of the upper mold mandrel 6 is also installed with Bending punch mechanism 7, under the blank holder 1 Flitch 8 is also installed on surface, the downside both ends of the flitch 8 are additionally provided with lower die 9, and the lower surface of the lower die 9 is also It is installed with parallels 10, in punch-forming mold, moved cross beam 3 moves down, and makes blank holder 1 to being fitted after positive lower die 9 and plate 8 When being pressed on plate 8, cylinder connector 4 pushes in the presence of cylinder, and pushes shot 15 by pressing plate 5, makes upper mold cover die 2 And upper mold mandrel 6 is promoted to plate 8 simultaneously, and until so that the pushing plate 8 of upper mold cover die 2 is leaned on 9 inner cavity of real lower die, the subsequent upper mold heart Axis 6 can continue to advance downwardly under the extruding of shot 15, until mould punching is molded, then cylinder be returned, and pass through bolt Drive upper mold mandrel 6 and upper mold cover die 2 to rise, until being detached from the mold that punching press is completed, finally rise moved cross beam 2, take out at Pattern has.
