Description
Technical field
The utility model relates to gearbox manufacturing equipment field, is specially a kind of mould for gearbox gear.
Background technology
Gear on automobile gearbox is the driving parts that automobile power exports, extremely important to vehicle safety travel.Its quality directly affects continuity, stability, the intensity quality decision driving safety of automobile power output.Gear is generally arranged on main shaft, is in idling conditions at ordinary times, engages through selector fork effect when shifting gears with idle pulley; Drive shifting shaft rotate backward (rotation direction relative to countershaft) and carried by power, thus realize gearshift needs.In prior art, the traditional processing method of this gear is machined, but its difficulty of processing is large, speed slow, need multiple stage special sew with long stitches tooth or gear shapping machine, investment is large; In addition, also have that material use is low, integrated cost is high, do not have the deficiencies such as the market competitiveness.
Chinese patent (notification number CN 202114203 U, day for announcing 2012.01.18) discloses reverse neutral gear tooth form opening angle cold-finishing mould for automobile gearbox, upper bolster is provided with cold-finish patrix, upper bolster arranges upper padding plate, and cold-finish patrix is arranged on below upper padding plate; Below cold extrusion patrix, correspondence arranges cold-finish counterdie, and cold-finish patrix is mutually corresponding with the die cavity of cold-finish counterdie, forms cold-finish die cavity after matched moulds; Described cold-finish counterdie is arranged on die shoe; Arrange push rod below cold-finish counterdie, the upper end of push rod can pass in the die cavity of cold-finish counterdie; Below push rod, arrange secondary push rod, during the demoulding, secondary push rod promotion push rod moves upward.But its complex structure, make efficiency are low, and operation is inconvenient, poor stability.
Utility model content
The technical problem that the utility model solves is to provide a kind of mould for gearbox gear, to solve the problem proposed in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of mould for gearbox gear, comprise: shaping upper, shaping counterdie, shaping upper lasso is provided with outside described shaping upper, shaping counterdie is provided with on the downside of shaping upper, shaping counterdie inside race is provided with outside shaping counterdie, be provided with shaping mould lasso outside shaping counterdie inside race, shaping upper lower end is embedded in shaping mould lasso, is provided with shaping counterdie ejection block in shaping counterdie.
Described shaping upper is embedded in shaping upper lasso, is provided with axis hole in the middle part of shaping upper lasso.
Described shaping counterdie inside race is conical structure.
Described shaping upper lower end is provided with locating slot, shaping counterdie upper end is provided with locating slot.
Described shaping counterdie ejection block is provided with jacking head.
Compared with prior art, the beneficial effects of the utility model are: the utility model not only formed precision is high, reduce the cost of part; Obtain the form of gear tooth easily and import angle, meet technological requirement; And increase substantially the production efficiency of part, meet the needs in market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of mould for gearbox gear, comprise: shaping upper 1, shaping counterdie 2, shaping upper lasso 4 is provided with outside described shaping upper 1, be provided with shaping counterdie 2 on the downside of shaping upper 1, outside shaping counterdie 2, be provided with shaping counterdie inside race 3, outside shaping counterdie inside race 3, be provided with shaping mould lasso 5, shaping upper 1 lower end is embedded in shaping mould lasso 5, is provided with shaping counterdie ejection block 6 in shaping counterdie 2.
Described shaping upper 1 is embedded in shaping upper lasso 4, is provided with axis hole in the middle part of shaping upper lasso 4.
Described shaping counterdie inside race 3 is conical structure.
Described shaping upper 1 lower end is provided with locating slot, shaping counterdie 2 upper end is provided with locating slot.
Described shaping counterdie ejection block 6 is provided with jacking head.
Operation principle of the present utility model is: be arranged on by shaping upper 1 in shaping upper lasso 4, shaping counterdie ejection block 6 is arranged in shaping counterdie 2, shaping counterdie 2 is arranged in shaping counterdie inside race 3, shaping counterdie inside race 3 is arranged in shaping mould lasso 5, then just workpiece to be processed is placed between shaping upper 1 and shaping counterdie 2, at the extruding compacted under of shaping upper 1, shaping counterdie 2.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
