the second side pressing material core is assembled on the upper pressing material core, the two ends of the second side pressing material core are provided with assembling steps, the second side pressing material core is hung on the upper pressing material core through the assembling steps, the contact surface of the second side pressing material core is provided with a self-lubricating guide plate, the second side pressing material core slides relative to the upper pressing material core, and a second nitrogen spring is tightly pressed on the second side pressing material core to provide a shaping side pressing force;
the specific structure of the driving part for driving the material supporting part to reciprocate left and right comprises the following steps: a wedge-shaped guide plate,
the driving block of the driving part is fixedly arranged on the upper die holder, and along with the downward movement of the upper die, the wedge-shaped lower end of the driving block is contacted with the wedge-shaped guide plate to push the driving part to move forwards, and the wedge-shaped guide sliding surface on the right side of the driving part is contacted with the wedge-shaped guide sliding surface on the left side of the material supporting part to guide sliding, so that the material supporting part is pushed to move rightwards; the wedge-shaped guide sliding surface on the right side of the driving part and the wedge-shaped guide sliding surface on the left side of the material supporting part form a wedge-shaped guide sliding part.
2. The shaping cam mechanism with double-sided pressing cores according to claim 1, wherein a first nitrogen spring is installed at the front end of the driving part and is in elastic contact with a third limiting block on the lower die holder.
3. The shaping cam mechanism with double sided swage core of claim 2, wherein said carrier part is driven out of the shaping profile after said one shaping movement is completed.
