Description
Technical field
This utility model is related to a kind of powder metallurgy forming device, 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 shaped device, 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 forming device, bag
Include upper die and lower die and annular core, annular core overcoat is connected to externally reinforced set；Described lower mould includes lower mould barrel chamber, lower mould cylinder
Intracavity is provided with lower mould top board, the lower surface of lower mould top board is provided with some lower mould push rods, the upper surface of lower mould top board sets
It is equipped with bottom die cavity；Described upper mould includes mould barrel chamber, and upper mould into the barrel chamber is provided with upper-mould top, on the lower surface of upper-mould top
It is provided with some upper mould push rods, the lower surface of upper-mould top is provided with top die cavity；The lower end of described upper mould barrel chamber and lower mould
The upper end of barrel chamber is socketed in annular core, the inner surface of annular core is provided with some circular orientation raised；Described upper mould
It is provided with charging hole on top board and lower mould top board.
Optimize, above-mentioned powder metallurgy forming device, described charging hole is bellmouth.
Optimize, above-mentioned powder metallurgy forming device, described lower mould push rod and upper mould push rod are bow.
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
