Double acting type side shaping device capable of improving strength of mold cores on body side

Abstract

The present invention proposes a double-moving side shaping device for improving the strength of the side surrounding mold core of the vehicle body, including an upper mold base, a lower mold base, an upper side binder plate, a lower side binder plate, a wedge slider, and a side shaping knife , positive pressure plate, lower horizontal movable mold core, vertical motion mold core and drive block; upper side pressure plate and positive pressure plate are located on the upper die base, lower side pressure plate, lower horizontal movable mold core, vertical Both the moving mold core and the driving block are located on the lower mold base; the lower horizontal movable mold core and the vertical moving mold core are connected with the driving block; On the side of the traditional positive pressure plate, the upper pressure plate is added. When the upper pressure plate is pressed, the normal force on the surface will be greater, and the pressure effect will be better; and it will no longer be used. Horizontally divided, there will be no weak mold; the upper and lower parts of the side shaping knife have side pressing plates for pressing, which avoids the wrinkling and surface defects of parts shaping.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a compound-action side shaping device for improving the strength of the side surrounding mold core of a vehicle body. Background technique [0002] The side panel of the car body is the largest outer cover on the car body, and it is also the most critical stamping part. The product quality and production stability of this part are very important. [0003] Some parts on the car are drawn at a negative stamping angle, which cannot be drawn in place. It can only be realized through the post-process side shaping mold. The side shaping double action mechanism is relatively common in automobile molds, and there are many structural methods. It depends on different part shapes, different mold space requirements, and different production methods. [0004] In the prior art, the overlapping surface between the upper part of the side wall of the automobile body and the top cover a...
