[0035] During use, the rear end of the mold main frame 1 is connected to a feeding device for conveying terminals, enabling the terminals to move forward automatically without manual intervention, which is extremely convenient.

[0036] The main body frame 1 of the mold has stroke arms A13 and B14 installed on both sides, which are detachably connected by screws. Cylinder fixing plate A and cylinder fixing plate B are fixed to the ends of stroke arms A13 and B14 by screws, respectively. Cylinder A29 and cylinder B30 are fixedly connected to cylinder fixing plate A and cylinder fixing plate B by screws, respectively.

[0037] Stroke arms A13 and B14 are detachably connected to guide rails A31 and B32 respectively via screws; guide rails A31 and B32 are respectively equipped with stroke guide blocks A15 and B16 that cooperate with them. One end of stroke guide blocks A15 and B16 is connected to cylinders A29 and B30 respectively, and the other end of stroke guide blocks A15 and B16 is connected to pusher pin A and pusher pin B respectively.

[0038] The piston rod of the cylinder moves, and the stroke guide block slides along the guide rail, thereby driving the pusher pin to move forward. The pusher pin moves the terminal forward, realizing automatic feeding. The cylinder retracts, so that the stroke guide block returns to its original position, and then the next working cycle begins.

[0039] The mold main body frame 1 is provided with a mold bottom plate 35 at the bottom, and the mold bottom plate 35 is provided with a positioning plate A 21, a positioning plate B 22 and a positioning plate C 23. The distance between the positioning plate A 21, the positioning plate B 22 and the positioning plate C 23 can be adjusted, so that the distance is equal to the width of the terminal, so as to fix the terminal. When the pushing material pushing needle moves the terminal, the positioning plate can prevent the terminal from moving left and right during the movement.
