It also comprises a shell transfer mechanism 3 arranged on one side of the mounting frame 2, a PIN pin clamping mechanism 4 arranged on the other side of the mounting frame 2, and a PIN pin end pressing mechanism 5 arranged on the mounting frame 2. The PIN pin clamping mechanism 4 comprises a plurality of jigs 41 arranged in the X direction on the mounting frame 2, a plurality of clamping assemblies 42 arranged on the mounting frame 2 and corresponding to the plurality of jigs 41, and a push positioning assembly 43 arranged on the mounting frame 2 for synchronously fixing the PIN pins 200 on the plurality of jigs 41.

The clamping claw 434 comprises a vertical plate 401, a horizontal plate 402 arranged on the vertical plate 401, and three clamping blocks 403 arranged in the X direction on the horizontal plate 402.
[0022] It should be noted that the PIN pin 200 comprises a No. 1 PIN pin 201, a No. 2 PIN pin 202, and a No. 3 PIN pin 203. For the sake of subsequent description, they are collectively referred to as three PIN pins 200.
[0023] In actual use, when the external mold is completed injection molding, the PIN pin and the shell form a finished product at this time. The mounting frame 2 is driven to move by the mechanical arm 1, so that the shell clamping mechanism 3 downwardly adsorbs the shell 100 in the mold. Then the mounting frame 2 is driven to rotate by the mechanical arm 1, so that the PIN pin clamping mechanism 4 downwardly places the PIN pin 200 in the external mold. Then the mounting frame 2 is driven to move by the mechanical arm 1, and the finished product is placed on the collection station by the shell clamping mechanism 3. Subsequently, the PIN pin clamping mechanism 4 re-clamps one end of the PIN pin to be injection molded, and the PIN pin end pressing mechanism 5 fixes the other end of the newly clamped PIN pin 200. The working principle of the PIN pin clamping mechanism 4 is as follows: the jigs 41 are moved by the mounting frame 2, and then the PIN pins 200 on the cutting station are corresponded to the jigs 41. Then the clamping assemblies 42 clamp one end of the PIN pins 200. Subsequently, the mounting frame 2 is moved upwardly by the mechanical arm 1, and at this time the PIN pins 200 are fixedly moved by the clamping assemblies 42. When the movement space reserved for the push positioning assembly 43 is reached, the clamping claw 434 is driven by the No. 1 air cylinder 433 to move to the side of the jig 41, so that the three clamping blocks 403 of the same clamping claw 434 press the other ends of the three PIN pins 200 on the jig 41.
