[0019] 4. In the present invention, as the blocking plate descends to the same horizontal line as the bottom of the solid mold, the blocking plate and the connecting strip stop moving. As the flexible strip continues to descend, the flexible strip will deform until it is separated from the connecting strip. Under the action of the spring, the connecting strip and the blocking plate are driven to reset upward, thereby ensuring the integrity of the inside of the solid mold and also improving the subsequent stamping quality of the silicon steel sheet. At this time, the hydraulic cylinder stops working, and the staff places the silicon steel sheet to be stamped on the solid mold, and continues to start the hydraulic cylinder to drive the movable mold to continue to descend to complete the stamping of the silicon steel sheet.

[0022] 7. In the present invention, a collecting box is provided to recover the lubricating oil dripping from the lower side of the connection between the outer surface of the guide rod and the bracket.
