It includes a die frame, with a material conveying component at the front. An upper die and a lower die are respectively installed in the upper and lower parts of the die frame's inner cavity. The material conveying component includes a material conveying drive block slidably mounted on the die frame. The end of the material conveying drive block is connected to a material conveying adjustment rod, and the end of the material conveying adjustment rod is connected to a material conveying control box. The bottom of the material conveying control box is connected to a material conveying telescopic rod, and the bottom of the material conveying telescopic rod is connected to a material conveying suction cup.
