The lower die 12 slides down synchronously with the lower die 9 as the lower die 9 slides down continuously while the lower die 9 contacts with the top of the side wall of the lower die 12 in the process of sliding down. In the process of sliding the lower die 12 downwards, the molding material in the lower die 12 is jacked up by the ejector pins 15 on the lower die holder 3, so that the bottom of the molding material is separated from the lower die 12. At this time, the spring 13 at the top of the lower die holder 3 is in a compressed state.
When the bottom of the molding compound is completely separated from the lower mold 12. The push rod 7 is started, the telescopic end of the push rod 7 can drive the supporting arm 8 to slide upwards, and the supporting arm 8 can drive the die cutter 9 to slide upwards. During the upward sliding of the die cutter 9, the lower die 12 returns to its original state due to the elastic action of the spring 13. In addition, the die cutter 9 contacts with the bottom of the side wall of the upper die 11 in the process of sliding upwards, and the upper die 11 slides upwards along with the die cutter 9 along with the continuous upward sliding of the die cutter 9. In the process of upward sliding of the upper die 11, the molding material in the upper die 11 is pushed down by the ejector pins 15 on the upper die holder 2, so that the top of the molding material is separated from the upper die 11, and the spring 13 at the bottom of the upper die holder 2 is in a compressed state.
After all the forming materials are separated from the die, the hydraulic rod 5 is started, the telescopic end of the hydraulic rod 5 drives the upper die plate 1 to move upwards, the upper die plate 1 moves upwards to drive the push rod 7 and the upper die holder 2 to move upwards, the push rod 7 moves upwards to drive the support arm 8, the die cutter 9 and the upper die 11 to move upwards, and when the upper die 11 moves upwards to a proper position, the forming materials are taken down.
