Description
Technical field
The utility model relates to valve guide bushing mould, particularly relates to a kind of valve guide bushing powder pressing forming mould.
Background technology
Valve guide bushing is important composition parts in automobile, motorcycle engine.Powder metallurgy forming is process powder being transformed into the agglomerate with required form, and powder metallurgy product is raw materials used is superfine particulate powder, and the powder mould of certain performance is pressed into blank.Current valve guide bushing often adopts powder metallurgy pressing, but existing valve guide bushing mould structure is complicated, complicated operation, and needs multiple operation.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use, once extruded valve guide bushing powder pressing forming mould.
For solving the problem, the utility model provides a kind of valve guide bushing powder pressing forming mould, described valve guide bushing powder pressing forming mould comprises upper punch, be provided with the bottom punch of cavity, the core bar matched with bottom punch and the former matched with upper punch and bottom punch, described core bar is located on described bottom punch, described core bar is also located in described upper punch, and described core bar can move relative to upper punch and bottom punch, the axial line of described bottom punch, the axial line of described upper punch and the axial line of former are located along the same line, described upper punch center is provided with the through hole matched with described core bar, the length of described core bar is greater than the length of described bottom punch, described core bar, bottom punch, upper punch and die combinations form valve guide bushing cavity.
Further, described upper punch is provided with groove away from the end face of former one end.
Further, described core bar is one-body molded.
Further, described core bar comprises connector, the first core bar body and the second core bar body, one end of described connector and described first core bar body is fixed, and the other end and the described second core bar body of described first core bar body are fixed, and the diameter of described first core bar body is less than the diameter of described second core bar body.
The utility model valve guide bushing powder pressing forming mould is matched with upper punch, bottom punch and core bar by former, and upper punch is squeezed in the powder in the cavity of plug, bottom punch and female die set synthesis, once extruded, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the better embodiment of the utility model valve guide bushing powder pressing forming mould.
Fig. 2 is the structural representation of upper punch.
Fig. 3 is the structural representation of core bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the better embodiment of the utility model valve guide bushing powder pressing forming mould comprise upper punch 2, be provided with the bottom punch 3 of cavity, the core bar 4 matched with bottom punch 3, the former 5 that matches with upper punch 2 and bottom punch 3.Described core bar 4 is located on described bottom punch 3, and described core bar 4 can move relative to bottom punch 3, and described core bar 4 is also located in described upper punch 2, and described core bar 4 can move relative to upper punch 2.Described upper punch 2, described bottom punch 3 and described former 5 are coaxially arranged, and namely the axial line of the axial line of bottom punch 3, the axial line of described upper punch 2 and former 5 is located along the same line.Described core bar 4, bottom punch 3, upper punch 2 and former 5 are combined to form valve guide bushing cavity.
Described upper punch 2 center is provided with the through hole 21 matched with described core bar 4, and described upper punch 2 is provided with groove 22 away from one end of described former 5, and groove 22 plays the effect of exhaust.
The length of described core bar 4 is greater than the length of described bottom punch 3, guarantees that core bar 4 energy and upper punch 2 coordinate.Described core bar 4 comprises connector 41, first core bar body 42 and the second core bar body 43, described connector 41 is fixed with one end of described first core bar body 42, the other end and the described second core bar body 43 of described first core bar body 42 are fixed, the diameter of described first core bar body 42 is less than the diameter of described second core bar body 43, and the second core bar 43 mates with upper punch 2; Described core bar 4 is one-body molded, facilitates the manufacture of technique.When extruding powder, the first core bar 42 is not in former 5.
During use, core bar 4 is moved and is located at position, powder is added in the cavity being combined into after reaching predeterminated position former 5, core bar 4 and bottom punch 3, after having fed in raw material, upper punch 2 moves down, it is made to extrude powder in cavity, when upper punch 2 arrives predeterminated position, valve guide bushing is extruded, simple and convenient.
These are only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model description and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
