[0002] TYPE-C is a type of USB, which is divided into TYPE-C female and TYPE-C male. The TYPE-C female is mainly composed of an upper body, a lower body, and a shell. The upper body is formed with an upper terminal, and the lower body is formed with a lower terminal and a middle steel sheet. At present, in the production process of the TYPE-C female, only one or two strips can be fed into the mold at the same time when loading. Due to the limitation of the hardware connection method, the single material is connected to the strip in parallel in a "straight line". The mold cavity on the stamping mold and the injection mold can only be arranged in a "straight line" form. When the mold length is limited, the output quantity of one mold is small, resulting in low production efficiency and difficulty in meeting production requirements. There are problems of high production costs and large material losses, which puts great pressure on production companies. Summary of the invention
