Specific implementation mode
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened completely is communicated to those skilled in the art.
Fig. 1 is to Fig. 2 shows the structural schematic diagrams of the material jacking mechanism of embodiment according to the present utility model offer.Such as figure
Shown in 1 and 2, hotdie forging press mould bases 200 includes top mold frame 21, lower mold holder 22, material jacking mechanism and mold 300.This liftout
Mechanism can pass through the liftout hole at 300 middle part of mold, and can be assemblied in the mould bases of hotdie forging press together with mold 300
In 200, material jacking mechanism includes upper plate 11, lower roof plate 13 and the liftout structure being arranged between upper plate 11 and lower roof plate 13
Part, ejector member include upper ejector beam 121 and bottom knockout bar 122, and after forging completes forging, the downside of upper plate 11 can be with
Upper ejector beam 121 offsets, and the upside of lower roof plate 13 can offset with bottom knockout bar 122, in upper plate 11 and/or the lower roof plate
Forging can be ejected from the cavity of the mold 300 under the action of 13.
In addition, upper plate 11 can be matched in the upper die holder of mould bases 200, lower roof plate 13 can be matched with mould bases 200
In lower die holder.
Upper plate 11 is set as fancy top plate as shown in Figure 3, and multiple upper ejector beams 121, example can be arranged on fancy top plate
Extension such as before and after this fancy top plate is arranged with upper ejector beam 121, that is, arranges four upper ejector beams 121.Lower roof plate
13 shape is identical as upper plate 11, and the utility model repeats no more.
