When the L-shaped rod 403 does not support the plate material, one end of the L-shaped rod 403 extends out of the mounting groove 402 under the action of the torsion spring 406. When the L-shaped rod 403 supports the sheet material, the L-shaped rod 403 can support the sheet material without rotating due to the action of the torsion spring 406. When the die is closed, the plate moves downwards, the L-shaped rod 403 is stressed to rotate forwards, and when the plate is pressed and formed, the L-shaped rod 403 does not support the plate any more, and the L-shaped rod 403 rotates reversely to return under the action of the torsion spring 406. When the molded product is discharged, the L-shaped bar 403 is moved upward and rotated in the reverse direction, and at this time, since the torsion spring 406 does not exert an elastic force on the L-shaped bar 403, the L-shaped bar 403 can be easily moved in the reverse direction and the molded product can be easily discharged. When the product is completely removed, the L-shaped bar 403 is rotated forward under gravity until one end of the L-shaped bar 403 extends straight out of the mounting slot 402.
