Description
Technical field
This utility model is related to a kind of powder metallurgy pressing mold, belongs to field of powder metallurgy.
Background technology
Powder metallurgy is to produce metal dust or use metal dust（Or the mixture of metal dust and non-metal powder）Make
For raw material, through shaping and sintering, manufacture the Technology of metal material, composite and all kinds product.Powder smelting
Jin Fayu produces pottery similar place, belongs to sintered powder technique, therefore, a series of New Technologies In Powder Metallu Rgies also can use
Preparation in ceramic material.Due to the advantage of PM technique, it has become the key solving the problems, such as new material, in new material
Development in play very important effect.Existing powder metallurgy die, finished product accuracy is low after shaping, needs to carry out secondary
Processing, have impact on processing progress.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of powder smelting
Golden pressing mold, finished product accuracy is high, facilitates production and application.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of powder metallurgy pressing mold, bag
Include upper die and lower die and annular core, annular core overcoat is connected to externally reinforced set, and the upper end of the lower end of upper mould and lower mould is socketed on
In annular core；Described lower mould includes lower mould top board, and the lower surface of lower mould top board is provided with lower mould push rod；Described upper mould includes
Upper-mould top, the upper surface of upper-mould top is provided with Upper Die-sleeve pipe, is provided with charging cavity, on upper-mould top in Upper Die-sleeve pipe
It is provided with charging hole, charging cavity and charging hole UNICOM, be provided with charging top board in feed cavity body, on the upper surface of charging top board
It is provided with charging push rod；The lower surface of described upper-mould top is provided with top die cavity, and the upper surface of lower mould top board is provided with down
Portion's die cavity.
Optimize, above-mentioned powder metallurgy pressing mold, the edge of described upper-mould top and lower mould top board is provided with some
Positioning convex, the inner ring surface of annular core is provided with some detents, and positioning convex and detent are equipped with.
Optimize, above-mentioned powder metallurgy pressing mold, described charging push rod is bow, the top of charging push rod is connected with
Lower platen.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.The application's
Design changes the structure of existing powder metallurgy die, by using annular core and externally reinforced set by upper die and lower die set
Connect, define a stable longitudinal extension structure so that mould degree of stability in the vertical improves, and then improve finished product vertical
Precision upwards.Powder materials are pushed in top die cavity and bottom die cavity charging top board, facilitate the entrance of powder materials, are not required to
Again mould is closed after powder materials are injected, prevent the upper die and lower die closure skew leading to because powder injection is uneven, enter one
Step improves the precision of mould.Charging push rod can be alleviated because pushing speed by feeding the elastic deformation of push rod for bow
The powder packed that inequality leads to is not complete.
