Existing automobile connecting bar uses hot forging molding mostly, and one-shot forming technique can ensure its mechanical performance, makes again working (machining) efficiency increase substantially.But one-time-shaped mould coordinates precision to require height, existing automobile connecting bar die-forging forming, owing at least one end, end of automobile connecting bar is provided with shaft hole, as shown in Figure 1, when die-forging forming, exist the coordinating of upper die and lower die inaccurate will the two ends end face molding effect of automobile connecting bar poor, and after die-forging forming, required point of mould power of point mould of upper die and lower die is relatively big, increases energy cost.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of accurate positioning, good forming effect and the forging mold of point convenient automobile connecting bar of mould.
nullThe purpose of this utility model is achieved through the following technical solutions: the forging mold of a kind of automobile connecting bar，It includes lower mold and upper mold，Lower mold and upper mold are alignd by location structure and position，The upper surface of lower mold is provided with the lower mode cavity consistent with the low profile of automobile connecting bar，The two ends of lower mode cavity are respectively arranged with lower mold post，It is protruding that the middle part of lower mode cavity is provided with lower mold，The lower surface of upper mold is provided with the upper cavity consistent with the top profile of automobile connecting bar，The two ends of upper cavity are respectively arranged with upper mold post，It is protruding that the middle part of upper cavity is provided with upper mold，Lower mode cavity、Upper cavity、Lower mold post、Lower mold is protruding、Upper mold post and upper mold convex to form the shaping mold cavity of automobile connecting bar，Described location structure is arranged at the edge of upper die and lower die，Location structure includes alignment pin、Hole, location、Spring base and spring，Multiple alignment pins are perpendicular to the upper surface of lower mold and arrange，The lower surface of upper mold is vertically provided with the location hole identical with alignment pin number，Alignment pin is respectively cooperating with being connected with hole, location，The upper end of alignment pin is provided with spring base，Spring housing is contained on spring base，The lower end of spring is pressed on the upper surface of alignment pin，Upper end is pressed on the top end face in hole, location.
Described shaping mold cavity is two, and the corner of each shaping mold cavity is respectively arranged with location structure.
The height of described lower mold post is higher than the height of upper mold post.
This utility model has the advantage that
1, the shaft hole of automobile connecting bar end is coordinated realization by upper mold post and lower mold post by this utility model so that the molding effect of automobile connecting bar end face, in shaft hole, is improved so that the quality of automobile connecting bar is effectively improved in the cooperation face of upper die and lower die.
2, being respectively arranged with detent mechanism on the corner of shaping mold cavity, upper die and lower die are realized precise positioning by detent mechanism, use hole pin to coordinate, and positioning precision is high, is conducive to improving the precision of die-forging forming.
3, the upper end at alignment pin arranges spring base, and pocketed springs on spring base so that there is a point mould trend between upper mold and lower mold after matched moulds, is conducive to point mould after die-forging forming, reduces energy-output ratio.
