To achieve these goals, the utility model adopts following technical scheme:
A kind of powder metallurgy injection (mo(u)lding) machine of raw material high usage, it comprises workbench, mould, upper stamping die, lower stamping die and powder feeding device, described mould offers die cavity, described mould is fixed on workbench, described upper stamping die and lower stamping die to lay respectively at above and below workbench and with die cavity centering;
Described powder feeding device comprises hopper, feed box, air supply source and leaks material suction source, be provided with feed chamber in described feed box, be surrounded on recovery chamber that feed chamber arranges, by injection channel with reclaim chamber jet and by suction passage with reclaim the material sucking port of chamber; The top of described feed chamber is communicated with hopper by the first flexible pipe, and described jet is connected with air supply source by the second flexible pipe, with leakage, described material sucking port expects that suction source is connected by the 3rd flexible pipe;
On described workbench, the outer side that is positioned at feed box is provided with driver, and described driver control feed box does feed motion relative to die cavity.
Preferably, the spatial altitude of described feed chamber is greater than the spatial altitude reclaiming chamber.
Preferably, the axis of described injection channel and the axis of feed chamber are parallel to each other, and the angle between the axis of described suction passage and the axis of feed chamber is greater than 0 °, is less than 90 °.
Preferably, described driver is hydraulic press.
Owing to have employed such scheme, the utility model passes through feed box and the structure improvement thereof of setting, makes powder feeding device have the functions such as feed, injection, the recovery of leakage material, drastically increases the utilization rate of raw material, reduce production cost; Its structure is simple, has very strong practicality.
Accompanying drawing explanation

Fig. 2 is the cross section structure schematic diagram of the feed box 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 depicted in figs. 1 and 2, the powder metallurgy injection (mo(u)lding) machine of the raw material high usage of the present embodiment, it comprises workbench 1, mould 2, upper stamping die 3, lower stamping die 4 and powder feeding device; Wherein, mould 2 offers die cavity 2-1, mould 2 is fixed on workbench 1, upper stamping die 3 and lower stamping die 4 to lay respectively at above and below workbench 1 and with die cavity 2-1 centering; The powder feeding device of the present embodiment then comprises hopper 5, feed box 6, air supply source 7 and leaks material suction source 8, in feed box 6, be provided with feed chamber 6-1, be surrounded on recovery chamber 6-2 that feed chamber 6-1 arranges, by injection channel 6-3 with reclaim the jet 6-4 that chamber 6-2 is communicated with and the material sucking port 6-6 be communicated with recovery chamber 6-2 by suction passage 6-5; The top of feed chamber 6-1 is communicated with hopper 5 by the first flexible pipe 9, and jet 6-4 is connected with air supply source 7 by the second flexible pipe 10, with leakage, material sucking port 6-6 expects that suction source 8 is connected by the 3rd flexible pipe 11; Meanwhile, on workbench 1, the outer side that is positioned at feed box 6 is provided with driver 12, and driver 12 can adopt the device such as hydraulic press, cylinder, motor+screw mandrel according to actual conditions.
So, when needs carry out metal dust supply to mould 2, driver 12 controls the top that feed box 6 moves to mould 2, make feed chamber 6-1 and die cavity 2-1 centering, at hopper 5 to while die cavity 2-1 feed, air supply source 7 provides air force by injection channel 6-3 in feed chamber 6-1, to ensure that metal dust is filled in die cavity 2-1 to greatest extent, after this, feed box 6 resets; Then, upper stamping die 3 and the relative motion of lower stamping die 4, to form unidirectional press power to the metal dust in die cavity 2-1; Due in the process of compacting, metal dust can become scattered about on workbench 1 because of the problems such as material of splashing, leak, therefore, when next working cycles, leak material suction source 8 meeting action in the process of feed box 6 motion, to make the raw material on workbench 1 be reclaimed in time, and then realize secondary utilization.
For ensureing the effect of leaking material recovery, the spatial altitude of the feed chamber 6-1 of the present embodiment is greater than the spatial altitude reclaiming chamber 6-2.Further, the axis of the injection channel 6-3 of the present embodiment and the axis of feed chamber 6-1 are parallel to each other, the angle of the axis of suction passage 6-5 then and between the axis of feed chamber 6-1 is greater than 0 °, is less than 90 °, best angle is preferably 45 ° or 30 °, so make suction passage 6-5 be tilting form, ensure the suction effect of leaking material.
Meanwhile, for avoiding Lou expecting that suction source 8 is in the process of suction, has a negative impact to die cavity 2-1, the sidewall between feed chamber 6-1 and recovery chamber 6-2 is provided with check valve (not shown).
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.
