Mold clean is relatively simple, has saved use cost, improves the service life of mold.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
The utility model provides a kind of normal direction multiple-piece tire-mold, including upper die and lower die, the upper die and lower die
Between be provided with die cavity, the die cavity is divided into upper cavity and lower mode cavity, and the upper cavity is equipped with several upper tread pieces, under described
Die cavity is equipped with several lower tread pieces, and the lower die bottom is equipped with normal direction pressurizing device, peace at the top of the normal direction pressurizing device
It is connected equipped with pressurization tracheae with die cavity.
As a kind of optimal technical scheme of the utility model, sealing element is provided between the upper mold and lower die, it is described
Clump weight is installed at the top of upper mold, it is described on be provided with and the matched upper tread plate of upper tread piece, the upper tread plate and upper mold
Between be provided with resistance glue air cleft, ventilation resistance glue air cleft is provided at the top of the die cavity.
As a kind of optimal technical scheme of the utility model, the lower die is provided with and the matched lower tread of lower tread piece
Plate is provided with lower resistance glue air cleft between the lower tread plate and lower die.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model is divided into multi-section point processing by upper die and lower die, and the product processing used time is shorter, shortens processing week
Phase, the upper tread plate of same size tire-mold and lower tread plate can be replaced, and intact component can be applied in combination again,
During tyre vulcanization extrusion forming, the gas that is discharged out of die cavity is needed by resistance glue air cleft discharge, and resistance glue air cleft can be with
Good venting quality and Mo Nei colloid mobility are provided, the defect generated in tyre vulcanization is reduced, improves tire yield rate, normal direction
Pressurizing device balanced can accurately pressurize into die cavity, prevent sidewall evagination caused by insufficient pressure, and mold clean is easier,
For gas vent without dredging, maintenance number is less, has saved use cost, improves the service life of mold.
