See accompanying drawing 3, existingly be directed in the development process of the powder metallurgy chain wheel of above-mentioned sprocket wheel, in order to realize the density of teeth portion, the mould of teeth portion position is divided into polylith, in former 20, arrange upper die and lower die, and patrix comprises outer patrix 21 and interior patrix 22, counterdie comprises outer counterdie 23, middle counterdie 24 and interior counterdie 25, wherein, interior patrix 22, middle counterdie 24 and interior counterdie 25 are for the formation of the web shape chamber mould of sprocket wheel, and outer patrix 21 and outer counterdie 23 are for the formation of the teeth portion shape chamber mould of sprocket wheel.Realized the interpolation of powder stock by outer patrix 21 and outer counterdie 23, achieve the requirement of teeth portion density.
Therefore, when using conventional powder metallurgy process to design, the structure of mould can be caused very complicated, also higher to the requirement of equipment, cause product and be subject to more restriction on stream.When particularly running into the part of some complicated structures, this situation is particularly evident.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of wheel disc sprills metallurgy component mould, under realizing the prerequisite of product teeth portion density requirements, simplifies the structure of mould, reduces the required precision of mould and equipment.
The technical scheme that the utility model is taked is:
A kind of wheel disc sprills metallurgy component mould, comprise former, it is characterized in that, in described former, arrange upper die and lower die, form the die cavity of part between described upper die and lower die, the inwall top edge of described former arranges chamfering.
Further, the integrated mould of described patrix.
Further, described part is sprocket wheel or gear, and have axis hole in the middle of described sprocket wheel or gear, the center on described upper die and lower die has the first through hole, in described first through hole, arrange the first plug.
Further, the web of described sprocket wheel or gear has some lightening holes, have the second through hole in the relevant position of described upper die and lower die, the second plug is set in described through hole.
Further, the axis hole of described sprocket wheel or gear arranges flange, described counterdie comprises outer counterdie, middle counterdie and interior counterdie, described outer counterdie and described patrix form the foreign steamer abdomen die cavity of described sprocket wheel or gear, described middle counterdie and described patrix form the die cavity of described flange, and described interior counterdie and described patrix form the interior wheel abdomen die cavity of described sprocket wheel or gear.
The beneficial effects of the utility model are:
(1) quantity of mould and length all reduce, and decrease process for making, reduce cost;
(2) simple for structure, mould bases does not need very complicated can meet density requirements.

Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to the utility model wheel disc sprills metallurgy component mould.
See accompanying drawing 4, overall structure and the existing mould structure of wheel disc sprills metallurgy component mould of the present utility model are similar, in former 6, arrange patrix 7 and counterdie 8, form the die cavity 9 of part between patrix 7 and counterdie 8, the inwall top edge of former 6 arranges chamfering 10.Wherein patrix 7 is a molds, and counterdie 8 is an entirety from part edge to middle part, coordinates with patrix 7 edge forming part.The marginal density of part requires to be realized by the inwall chamfering 10 of former 6.
See accompanying drawing 5,6, the inwall chamfering 10 of former 6 when loading powder raw material 11, because the secondary of mould rises, make the raw material 11 at chamfering 10 place to the position, flank of tooth shape chamber downstream to sprocket wheel, make the filling amount of flank of tooth position more than other position, when sintering, the density forming the flank of tooth is large.
