Detailed description of the invention
With embodiment, the utility model is described in further detail below, is not practical range of the present utility model is limited to this.
As shown in Figure 1, a kind of driven wheel internal spline external tooth mould, comprise upper bolster and die shoe, in described upper bolster, be provided with upper male mould structure, in die shoe, be provided with lower punch structure, between upper male mould structure and lower punch structure, be provided with lower cavity die 3 structures, upper male mould structure comprises punch retainer plate 1, punch retainer plate 1 lower end is provided with upper male mould 2, lower punch structure comprises downforce piece 8, downforce piece 8 upper ends are provided with lower punch fixed head 7, counterdie fixed head is equipped with stripping attachment 9, stripping attachment 9 lower ends are provided with material returned slide block 10, die shoe lower end is equipped with and one end and material returned slide block 10 lower push rod 11 being connected of conflicting, lower cavity die 3 structures comprise the upper pressure block 6 of being located at lower punch fixed head 7 upper ends, upper pressure block 6 upper ends are provided with material returning sleeve 5, material returning sleeve 5 upper ends are coated with profile of tooth die 4, in profile of tooth die 4, be provided with the lower cavity die 3 being equipped with upper male mould 2, the outer guard circle that is provided with of described profile of tooth die 4, guard circle lower end is provided with pressing plate 12, the utility model is by upper male mould structure, cooperation interlock between lower punch structure and lower cavity die 3 structures, and by material returning sleeve 5, cooperatively interacting of stripping attachment 9 and material returned slide block 10, the material of going out can be discharged, make like this product one-shot forming, can ensure yield rate, and processing is simple, efficiency is high.
When use, first material is positioned between upper male mould structure and lower cavity die structure, upper male mould structure presses down afterwards, make to expect that one-shot forming is axle shaft gear, meanwhile, promote to move on stripping attachment 9 by lower push rod 11, and coordinate with material returning sleeve 5, the material of going out is discharged, finally, by moving in upper male mould structure, axle shaft gear is taken out.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
