After the pressure is released, the mold is taken out of the container. After demoulding, the blank is further shaped as needed. The cold isostatic press is needed in the manufacture of long strip castings. According to the patent document entitled "Cold Isostatic Press Feeding Device" with the authorization announcement number CN211416441U, it is recorded in the specification that the device is coordinated by a cold isostatic press, a feeding hopper, a servo motor, a first crossbar, an annular tube, a circular blocking plate, an annular block, a first round rod, a first handle, a second handle, a spring and a first rotating block. When the cold isostatic press needs to be fed during use, the forward and reverse switch is first twisted, and the output shaft of the servo motor drives the first crossbar to rotate, the first crossbar drives the annular tube to rotate, and the annular tube drives multiple stirring rods to rotate. When the stirring rods rotate, blockage can be prevented during feeding. However, the following defects still exist:
