Description

A kind of mould of automobile rear-door waling part
Technical field
This utility model relates to a kind of diel, especially relates to the mould of a kind of automobile rear-door waling part Tool.
Background technology
When the covering of the large-scale vehicle bodies such as the tail gate waling currently for automobile carries out drawing, due to its zero Part profile is complex, there is bigger drawing depth poor, it is easy to produces side force when causing drawing on grinding tool, and then makes During punching press, mould guide-localization is unstable, so that the problems such as the most cracking during reinforcing plate forming parts, wrinkling, distortion, Affect parts drawing quality.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of automobile rear car is provided The mould of external door panel reinforcing plate part.
The purpose of this utility model can be achieved through the following technical solutions:
The mould of a kind of automobile rear-door waling part, including upper die body and lower mold body, described upper die body bag Including upper bolster and the drawing die being arranged on upper bolster, described lower mold body includes die shoe, this die shoe is additionally provided with The drawing punch that drawing die is corresponding, is provided with blank holder, the marginal portion of described blank holder in the marginal portion of drawing punch It is evenly distributed with multiple anti-side force slide guide face, upper bolster is provided with and the anti-side force of anti-side force slide guide face corresponding matching Guide plate.
Described blank holder be provided with cushion block further below, this cushion block and the push rod component that is fixedly mounted on die shoe are even Connect.
Described upper bolster is additionally provided with holding pad in the position with corresponding blank holder, is additionally provided with bead on holding pad, One end of bead is fixing with upper bolster to be connected, and the other end passes holding pad the surface beyond holding pad, described blank holder It is provided with blank holder groove in the position corresponding with bead.
It is additionally provided with elastic layer between described holding pad and upper bolster.
Described elastic layer is elastic dottle pin layer.
Be additionally provided with molding concave die on described upper bolster, flanging and restriking die separates die with punching, at molding concave die It is additionally provided with the drift for punching, described die shoe is additionally provided with the forming convax mould corresponding with molding concave die and flanging and restriking The flanging and restriking punch that die is corresponding, and the punching separating die with punching corresponding separates punch.
Described drawing die, molding concave die, flanging and restriking die separate die and are successively set in order with punching On die holder.
Described mould also includes that guide pillars and bushes, described guide pillar are arranged at four drift angles of die shoe, described Guide pin bushing is arranged at four drift angles of upper bolster, and during matched moulds, guide pillar is connected with guide pin bushing coupling.
Compared with prior art, this utility model has the advantage that
(1) by installing anti-side force guide plate on upper bolster, on blank holder, installation is mated with anti-side force guide plate Anti-side force slide guide face, so, when the die is closed, the anti-side force guide plate on upper bolster and the anti-side force slide guide face on blank holder It is slidably matched, such that it is able to it is lateral with what blank holder was formed by retroaction during draw forming effectively to control upper bolster Power, and then effective guarantee part position stability in drawing process.
(2) arranging of the elastic layer between holding pad and upper bolster can effectively eliminate the plate after draw forming Resilience, and then can ensure that the forming stability of the part after drawing.
(3) drawing, edge-cutting and hole-punching, flanging and restriking, punching are separated 4 combination of actions together by this utility model, just become Traditional four achievable parts of operation are completed by continuous combination die with a secondary mould, and centre eliminates three jig frequencies, Reduce production cost, improve the stability that part produces.
