Description
Technical field
The utility model relates to powder metallurgy die technical field, the compensation powder metallurgy filling mould of especially a kind of raw material.
Background technology
Powder metallurgic method be one utilize press by compressing for metal dust be pie, the solid form such as stepped, made the process of metallic article after shaping again by sintering.When compacted products, owing to there is the impact of the factors such as air-flow in be pollinated material poor fluidity, die cavity, easily there is the problems such as powder splashes, filler is not enough, and then make the quality of shaping rear product, volume and wall thickness equal-specification parameter not reach requirement.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of raw material compensation powder metallurgy filling mould.
To achieve these goals, the utility model adopts following technical scheme:
The compensation powder metallurgy filling mould of a kind of raw material, it comprises mould, upper stamping die and lower stamping die, and described mould offers central cavity, and described upper stamping die and lower stamping die lay respectively at the two ends of central cavity; Feed supplement chamber is provided with on described mould, around the upper end of central cavity, the sidewall of described central cavity offering the feed supplement runner for being connected with central cavity in feed supplement chamber, in described feed supplement chamber, being provided with the memory metal block of the external port for involution feed supplement runner;
Described upper stamping die comprises main press moulded bodies and side pressure die sleeve, and during described main press moulded bodies is relative with central cavity, the contraposition of described side pressure die sleeve is embedded in feed supplement chamber, between sidewall in feed supplement chamber of the tail end of described side pressure die sleeve and memory metal block.
Preferably, the wall thickness of described side pressure die sleeve becomes large gradually by its tail end head-end direction.
Preferably, the madial wall of described side pressure die sleeve is globoidal structure.
Preferably, the position at the external port place of described feed supplement runner is positioned at the top of its inner port position.
Preferably, the inner port of described feed supplement runner is several ring weeks and the mouth position be distributed in uniformly on central cavity sidewall.
Owing to have employed such scheme, the utility model utilizes feed supplement chamber to insert metal dust in advance, when upper stamping die presses down, under the acting in conjunction of side pressure die sleeve and memory metal block, the metal dust in feed supplement chamber can be made to enter in central cavity by feed supplement runner, compensate with the powder forming central chamber, to compensate the dust losses being splashed by race powder or powder and caused, thus ensure the quality of final products; Its structure is simple, has very strong practicality.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the compensation powder metallurgy filling mould of raw material of the present embodiment, it comprises mould 1, upper stamping die 2 and lower stamping die 3, mould 1 offers central cavity 4, and upper stamping die 2 and lower stamping die 3 lay respectively at the two ends of central cavity 4, upper stamping die 2 and lower stamping die 3 is utilized to apply pressure, to make it shaping to the metal dust in central cavity 4 with this.Owing to central cavity 4 can be made to form airtight cavity body structure when upper stamping die 2 and lower stamping die 3 are embedded in central cavity 4, in the starting stage, due to the effect of air-flow, the metal dust of central cavity 4 there will be the problem of running powder or powder splashing, thus have impact on the quality of shaped article, for evading this problem, on mould 1, upper end around central cavity 4 is provided with feed supplement chamber 5, the sidewall of central cavity 4 offers the feed supplement runner 6 for being connected with central cavity 4 in feed supplement chamber 5, simultaneously, the memory metal block 7 of the external port for involution feed supplement runner 6 is provided with in feed supplement chamber 5, accordingly, the upper stamping die 2 of the present embodiment comprises main press moulded bodies 21 and side pressure die sleeve 22, during main press moulded bodies 21 is relative with central cavity 4, side pressure die sleeve 22 contraposition is embedded in feed supplement chamber 5, simultaneously between the sidewall of the tail end of side pressure die sleeve 22 in feed supplement chamber 5 and memory metal block 7.So, feed supplement chamber 5 can be utilized to insert metal dust in advance, when upper stamping die 2 presses down, under the acting in conjunction of side pressure die sleeve 22 and memory metal block 7, the metal dust in feed supplement chamber 5 can be made to enter in central cavity 4 by feed supplement runner 6, compensate with the powder forming central chamber 4; And when upper stamping die 2 resets, memory metal block 7 to reset simultaneously, to carry out filler to feed supplement chamber 5; By said structure, compensate for the dust losses being splashed by race powder or powder and caused, ensure that the quality of final products.
For ensureing that metal dust in feed supplement chamber 5 can smoothly in metal center die cavity 4, the wall thickness of the side pressure die sleeve 22 of the present embodiment becomes large gradually by its tail end head-end direction.So, side pressure die sleeve 22 pairs of memory metal blocks 7 can be made to apply external force gradually, make it produce deformation, with final, stress be applied to the powder in feed supplement runner 6.Further, the madial wall of the side pressure die sleeve 22 of the present embodiment is preferably globoidal structure.
For ensureing that metal dust flows smoothly, the position at the external port place of the feed supplement runner 6 of the present embodiment is positioned at the top of its inner port position (namely in oblique layout); So, while External Force Acting, metal dust also can strengthen flow effect under gravity.
Further, the inner port of the feed supplement runner 6 of the present embodiment adopts mouth bit architecture, several mouthful of position ring week and the mouth position be distributed in uniformly on central cavity 4 sidewall, carries out feed supplement with the surrounding to greatest extent from central cavity 4.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process
Conversion, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
