A forging method for a mold with an adjustable forging surface, including the following steps:

S1. Place the mold blank to be forged on the top of the mounting base, and then start the reduction motor. The reduction motor drives the screw to rotate. When the screw rotates, it will drive the moving block to move. When the moving block moves, it will drive the connecting rod, support rod and fixed rod.

Compared with the prior art, the beneficial effects of the present invention are:

1. In the present invention, after the driving motor is running, through the rotation of the disk, the extrusion block above the disk can squeeze the inner wall of the moving groove. Since the directions of the two moving grooves are perpendicular to each other, the two disks The rotation can drive the mounting plate and the mounting base to move in two directions, and the moving directions are perpendicular to each other. Due to the two-way movement of the mounting plate, when debugging the forging surface of the mold blank, that is, forging different positions of the mold blank, through the installation The two-way movement of the plate can more conveniently adjust the position of the mold blank, thereby debugging the forging surface of the mold blank, which improves the convenience of use of the device.

2. In the present invention, through the design of the clamping mechanism, workers do not need to rotate the bolts back and forth for a large number of turns when clamping the mold blank, which reduces the labor intensity of workers and at the same time, due to the opposition of the two clamping plates By moving in the direction, the mold base is always in the middle position of the mounting seat, which reduces the possibility of the mold base being offset during clamping and improves the stability of the device.

3. In the present invention, since the clamping block and the fixed rod are slidingly connected and then snap-fitted, through this design, when one side of the clamping block is worn after being used for a long time, when replacing it, you only need to pull the pull ring to release the limit.
