during production, the first step: firstly, separating each cavity split die (4) of a vulcanizing die to a set gap, after each cavity split die (4) is separated, enabling the distance between two adjacent cavity split dies (4) to be smaller than the width of a shock absorber (100), enabling the distance between two sealing glue rods (46) matched with the two adjacent cavity split dies (4) to be larger than the length of a mounting boss (104) of the shock absorber (100), placing a top plate (101) and a bottom plate (102) of the shock absorber (100) between the two cavity split dies (4), enabling a power source (51) to pull a pulling plate frame (52) to reset, and enabling the pulling plate frame (52) to pull each cavity split die (4) to be folded; then, the vulcanizing machine drives the lower die (6), the cavity split die (4), the runner plate (3) and the runner base plate (2) to be assembled, and injection production is carried out; and a second step of: firstly, a vulcanizing machine drives a lower die (6), a cavity split die (4), a runner plate (3) and a runner base plate (2) to split; then, pins of the die divider (7) are inserted into pin holes of the pulling plate frame (52) and the cavity split dies (4), the power source (51) pushes the pulling plate frame (52) to advance, each cavity split die (4) is driven to advance in sequence, each cavity split die (4) is separated to a fixed position, the die divider (7) and the damper (100) are removed, and the first step is returned for production again.
2. The track damper split combined cavity vulcanizing mold of claim 1, wherein: an overpressure sealing structure (49) matched with the end face of a top mounting boss (104) of the shock absorber (100) is arranged around the sealing rod (46).
3. The track damper split combined cavity vulcanizing mold of claim 1, wherein: locking oblique blocks (61) are arranged at two ends of the lower die (6), and inclined planes matched with the locking oblique blocks (61) are arranged on the side surfaces of the two cavity valve dies (4) contacted with the locking oblique blocks (61).
4. The track damper split combined cavity vulcanizing mold of claim 1, wherein: the two inner side surfaces of the lower hanging die frame (5) are provided with L-shaped rails, and the two ends of the cavity die (4) are provided with steps (47) matched with the L-shaped rails.
