[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0040] When the Pin needle 5 of the F-type connector is formed, the main body 4 of the F-type connector is first placed in the positioning cavity of the main body of the F-type connector of the lower die for positioning. The Pin needle 5 of the F-type connector extends out of the positioning cavity of the main body of the F-type connector and is just flat against the Pin needle bending punch 2; the stamping equipment is started, and the upper die is pressed down. First, the upper die active pressure block 6 contacts the main body 4 of the F-type connector, and the bending punch and the cutting punch 8 are both at a certain distance from the Pin needle 5 of the F-type connector. As the upper die continues to descend, the pressure driving spring 9 is compressed, and at the same time, the main body 4 of the F-type connector is pressed and fixed in position by the upper die active pressure block 6. The bending punch 7 begins to contact the Pin needle 5 of the F-type connector, and the cutting punch 8 is still at a distance from the Pin needle 5 of the F-type connector. The upper die continues to descend. During the descending process, the bending drive spring 10 is gradually compressed, and the bending forming punch 7 bends the Pin needle 5 of the F-type connector twice to form a "Z" shape. When the bending forming punch 7 completes the bending of the Pin needle 5 of the F-type connector, the cutting punch 8 begins to contact the end of the Pin needle 5 of the F-type connector, and as the upper mold descends into place, the cutting punch 8 cuts off the excess part of the Pin needle 5 of the F-type connector, thereby realizing the fixed-length cutting of the Pin needle 5 of the F-type connector. The above-mentioned mold structure is simple, and the bending and fixed-length cutting of the Pin needle 5 of the F-type connector can be completed in one mold without two molds, thereby reducing the mold cost and the labor cost of the operator, and avoiding the cumulative error caused by two positioning to the product molding, thereby ensuring the stability of the product molding size.

[0041] The lower die is fixedly embedded with a lower die forming block 11, and a horizontal support surface 12 and an axial stop boss 13 are formed on the upper side of the lower die forming block 11.

[0042] When the lower die forming block 11 is embedded in the lower die, the upper end of the axial stop boss 13 on the lower die forming block 11 is flush with the upper side surface of the lower die, and the vertical side wall of the axial stop boss 13, the horizontal supporting surface 12, the vertical side wall on one side of the Pin needle bending punch 2 and the side wall of the embedding groove of the lower die for embedding the lower die forming block 11 together form a receiving groove that matches the shape of the main body 4 of the F-type connector. After the main body 4 of the F-type connector is placed in the receiving groove, the main body 4 of the F-type connector is in a horizontal and flat state, and the limit pin 14 on the lower die forming block 11 can fit tightly against the two circumferential side walls of the main body 4 of the F-type connector, thereby realizing precise positioning of the main body 4 of the F-type connector in the horizontal direction. After being pressed by the upper die movable pressing block 6, it can be ensured that it is firmly and stably positioned in the receiving groove, and the Pin needle 5 of the F-type connector in this position state is convenient for bending and also meets the positioning requirements of fixed-length cutting.
