The bent die of the upper frame of the automobile door hinge comprises an upper die structure and a lower die structure. The upper die structure is composed of an upper plate, an upper die foot is arranged on the upper portion of the upper plate, and an upper fixed plate is arranged on the lower portion of the upper plate by an upper padding plate. The lower die structure is composed of a lower plate, a lower fixed plate is arranged on the upper portion of the lower plate by a lower padding plate, a lower die foot is arranged on the lower portion of the lower plate, and a compound die is guided by a sliding guide pillar component between the upper plate and the lower plate. The bent die of the upper frame of the automobile door hinge is characterized in that a bent die is arranged in the upper fixed plate, a bent terrace die is arranged in the lower fixed plate, the bent die is matched with the profile of the bent terrace die, a positioning ejection pin is arranged in the bent terrace die, the positioning ejection pin penetrates through the bent terrace die from bottom to top, and is inserted into a positioning hole of a tablet to be machined, and a limit hole is formed in the bent die, right corresponding to the position of the positioning ejection pin.

Description

A kind of Bending Mould of automotive door hinge upper bracket

Technical field

The utility model relates to the processing technique field of auto parts and components, is specially a kind of Bending Mould of automotive door hinge upper bracket.

Background technology

A kind of automotive door hinge upper bracket, its tablet Bending Processing that needs to be " recessed " font becomes " several " font, see Fig. 1, Fig. 2 and Fig. 3, because this workpiece is that thin-wall part and bending and forming face are simpler, added in the past and mostly be artificial directly bending and forming man-hour or adopt easy diel directly to be stamped to form, it often exists, and the workpiece bending and forming is not in place, the problem of bending dimension overproof.

Summary of the invention

For the problems referred to above, the utility model provides a kind of Bending Mould of automotive door hinge upper bracket, and it can guarantee the reliable Accurate Shaping of workpiece, guarantees crudy.

Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises cope match-plate pattern, described cope match-plate pattern top is equipped with the patrix pin, the bottom is equipped with upper mounted plate by upper padding plate, described lower die structure comprises lower bolster, described lower bolster top is equipped with bottom plate by lower bolster, the bottom is equipped with the counterdie pin, between described cope match-plate pattern and the lower bolster by slip guide pillar assembly guiding matched moulds, it is characterized in that: in the fixed plate bending female die is installed, the bending punch is installed in the described bottom plate, described bending female die and bending punch surface are carved and are closed, in the described bending punch location ejector pin is installed, described location ejector pin inserts in the locating hole of tablet to be processed described bending female die after passing described bending punch from bottom to top, position over against described location ejector pin has spacing hole.

It is further characterized in that:

Jacking block and patrix mold insert in the middle of described bending female die comprises, described patrix mold insert is provided with two, jacking block and described two patrix mold insert amalgamation inserts are in fixed plate framed in the middle of described, and described two patrix mold inserts are positioned at the left and right sides of described centre jacking block;

Described bending punch comprises convex module and counterdie mold insert, described convex module is over against described middle jacking block, described counterdie mold insert is provided with two, described convex module and described two counterdie mold insert amalgamation inserts are in described bottom plate framed, and described two counterdie mold inserts are positioned at the left and right sides of described convex module;

Described location ejector pin vertically passes described lower bolster, lower bolster and convex module from bottom to top successively, and ejector pin bottom, described location is installed in the described bottom plate by Rectangular Spring.

Adopt the utility model mould that automotive door hinge upper bracket tablet is carried out Bending Processing, its beneficial effect is: it reliably is positioned tablet to be processed for the convex module surface by the location ejector pin, cooperate tablet stamping by bending female die with the bending punch again, thereby guarantee that the tablet bending puts in place, guarantees crudy.
