[0014] Referring to the accompanying drawings, this utility model includes: a limiting sleeve 8, an upper cutting mold 4, a positioning pin 5, and a lower cutting mold 9. Both the upper cutting mold 4 and the lower cutting mold 9 have mold cavities designed according to the shape of the buffer pad. The mold cavities contain cutting blades arranged according to the shape of the buffer pad. The mold cavity of the upper cutting mold 4 can be inserted into the mold cavity of the lower cutting mold 9, so that the upper cutting blade 6 of the upper cutting mold and the lower cutting blade 7 of the lower cutting mold 9 are in a cutting state. Both the upper cutting mold 4 and the lower cutting mold 9 have longitudinal center holes. The lower cutting mold 9 is placed inside the limiting sleeve 8, and the positioning pin 5 is inserted into the center hole of the lower cutting mold 9. The mold cavity of the upper cutting mold 4 and the mold cavity of the lower cutting mold 9 are correspondingly placed on the upper part of the lower cutting mold 9, and the upper end of the positioning pin 5 is inserted into the center hole of the upper cutting mold 4.

[0015] The NM coupling buffer pad mold is equipped with a mold frame 10. The mold frame 10 consists of a bottom plate, a top plate, and two opposing side plates connected between the bottom plate and the top plate. A pressing hole is opened on the top plate, and a pressing rod is installed in the pressing hole. The lower end of the pressing rod is connected to a pressing plate.

[0016] In this embodiment, the buffer pad is processed manually. To save effort, the pressing hole is made into a threaded hole, the pressing rod is a spinning screw 2, the pressing plate is a spinning plate 3, and a spinning handle 1 is set on the upper end of the spinning screw 2.

[0017] During processing, the lower cutting die 9 is placed inside the limiting sleeve 8, and the buffer pad blank to be processed is placed on the mold cavity of the lower cutting die 9. The positioning pin 5 is inserted into the center hole of the lower cutting die 9. The mold cavity of the upper cutting die 4 corresponds to the mold cavity of the lower cutting die 9 and is placed on the upper part of the lower cutting die 9. The upper end of the positioning pin 5 is inserted into the center hole of the upper cutting die 4. The entire NM coupling buffer pad mold is moved between the two side plates of the mold frame 10. The spinning handle 1 is manually rotated so that the spinning plate 3 presses the upper cutting die 4 downward. The mold cavity of the upper cutting die 4 can be inserted into the mold cavity of the lower cutting die 9, so that the upper cutting die 4 presses the buffer pad blank into the mold cavities of the upper cutting die 4 and the lower cutting die 9. The upper cutting blade 6 of the upper cutting die 4 and the lower cutting blade 7 of the lower cutting die 9 cut each other, completing the cutting process of the buffer pad blank placed therein.
