The two-shot molding process comprises the following steps of (1) putting a metal frame and a plurality of conductive terminals into an injection mold for positioning; (2) carrying out mold closing and first injection molding to mold an insulating body and forming a first module; (3) carrying out mold splitting, separating a terminal positioning part from the insulating body and forming a hollow part on a tongue plate; (4) dragging the first module to a second molding position of a male mold for second injection molding, filling the hollow part with plastic to mold a terminal separating and positioning block, and embedding, molding and fixing the terminal separating and positioning block and the first module together to form a second module; (5) coating the outer surface of the second module with a shielding case, carrying out dispensing between a protrusion part of the insulating body and the inner wall of the shielding case to form a waterproof plate, and embedding, molding and fixing the waterproof plate and a semi-finished product together to form the semi-finished product; and (6) finally mounting agland on the surface of the shielding case to form a finished product. The two-shot molding process is simple in assembly process and the overall strength of the connector is improved.
