The movable end of the material picking lifting cylinder 52 is connected to a second material picking component 53. The structure of the second material picking component 53 is the same as that of the first material picking component 310. The difference is that: based on the different shapes of the sheet metal sheet 8 before and after bending, the end face of the first material picking connecting seat 3101 of the second material picking component 53 is different from the end face of the first material picking connecting seat 3101 of the first material picking component 310. The end face of the first material picking connecting seat 3101 of the first material picking component 310 is planar, and protrusions are formed around the end face of the first material picking connecting seat 3101 of the second material picking component 53, so that the end face of the first material picking connecting seat 3101 of the second material picking component 53 is formed with a connecting cavity that is compatible with the bent sheet metal sheet 8, so as to facilitate the limiting of the bent sheet metal sheet 8.

[0075] After the bent sheet metal piece 8 is adsorbed by the second material taking component 53 , the robot arm of the injection molding machine drives the material taking unit 5 to rotate the bent sheet metal piece 8 into the injection mold in the injection molding machine.

[0076] Furthermore, if Fig.13 and Fig. 9 As shown, a material taking guide rod 54 is provided on the material taking support 51 , and a material taking guide hole 55 matching with the material taking guide rod 54 is provided on the lower die base 411 .

[0077] In this embodiment, during operation, a stack of sheet metal sheets 8 to be bent is placed into the storage bin 21; the lifting assembly 22 lifts the sheet metal sheets 8 to a preset position;

[0078] At this time, under the action of the Y-direction moving unit 6, the lower die assembly 41 moves to the material handling position of the bending and material handling unit 3; the bending and material handling unit 3 carries the uppermost sheet metal piece 8 to the bending punch 412 of the lower die assembly 41 for positioning, and absorbs the sheet metal piece 8 to prevent the product from shifting during the movement;

[0079] Then, the lower mold assembly 41 is moved to the position directly below the upper mold assembly 42 by the Y-direction motion unit 6; the upper mold assembly 42 cooperates with the lower mold assembly 41 to bend the sheet metal sheet 8 and heat it for 8 seconds, and the bending is completed; after the bending is completed, the lower mold assembly 41 is moved to the position where the robot of the injection molding machine takes the material by the Y-direction motion unit 6;

[0080] The robot of the injection molding machine takes the bent sheet metal sheet 8 through the material taking unit 5 and puts it into the injection mold in the injection molding machine for injection molding. The material taking unit 5 needs to be installed on the robot of the injection molding machine; the lower mold assembly 41 returns to the material handling position of the bending and material handling unit 3 through the Y-axis motion unit 6, thereby completing a cycle.
