Abstract

The utility model discloses a tire mould which belongs to the technical field of tire manufacturing apparatus. The utility model comprises an upper cover plate with an upper lateral plate, a bottom plate with a lower lateral plate, and 8-12 flower pattern blocks which are arranged at the outer sides of the upper lateral plate and the lower lateral plate, wherein the outer sides of the flower pattern blocks are tightly and fixedly provided with smooth blocks, and the outer sides of smooth blocks are connected with a driving device. A sliding device which is composed of sliding blocks and a wearing plate is arranged in the upper cover plate, wherein the sliding blocks are tightly and fixedly connected with the smooth blocks. The utility model drives the flower pattern blocks and the bottom plate with a lower lateral plate to open and close by the vertical acting force of a vulcanizing machine, and the utility model drives the corresponding sliding device, the smooth blocks and the flower pattern blocks to make open and close motion in a radial direction by the driving device. The motion travel route is in a motion mode of two straight lines, and the utility model has the advantages of simple operation, quick operation and exact positioning.

Description

Tire-mold

Technical field

The utility model discloses a kind of tire-mold, belong to the tire manufacturing equipment technical field.

Background technology

But traditional tire-mold dimidiation pattern tire-mold and active pattern tire-mold wherein again based on active pattern tire-mold, place in the vulcanizer.As shown in Figure 1, its structure mainly comprises 8-12 Hough mechanism and the corresponding angled-lift splits 5 that places between epipleural 1, upper cover plate 2, lower side panel 3, the base plate 4, pattern block 7 is housed on the angled-lift splits 5, and Hough mechanism is made up of middle die sleeve 8, limited block 9, oblique gib block 6.During work, vulcanizer acts on Hough mechanism, drives angled-lift splits 5, pattern block 7, epipleural 1, upper cover plate 2 motions by Hough mechanism, thus finish and lower side panel 3, base plate 4 between open and close, i.e. the die sinking of tire-mold or matched moulds motion.In this process, because of the Hough mechanism action is to finish by the mutual motion between middle die sleeve 8, limited block 9, oblique gib block 6 and the angled-lift splits 5, each parts closely cooperates and the synchronism of each Hough mechanism during die sinking when reaching matched moulds, this just needs each parts that high dimension precision will be arranged, this makes tire-mold manufacturer to spend huge sums and buys the large-scale high-precision lathe, manufacturing cost increases, but total quality does not reach the effect of anticipation.

Summary of the invention

The utility model purpose is to provide a kind of opening and closing mould motion simple and direct, the tire-mold of accurate positioning.

For achieving the above object, the technical scheme that the utility model adopted is: tire-mold, comprise the upper cover plate of being with epipleural, the base plate of band lower side panel, place epipleural and the lower side panel outside and form the 8-12 piece pattern block of a closed inner chamber with epipleural and lower side panel, the all fastening smooth block that is equipped with in the 8-12 piece pattern block outside, the smooth block outside all is connected with drive unit, 8-12 the carriage of being made up of slide block and wearing plate is housed, wherein slide block and corresponding all one by one fastening linking to each other of smooth block in the upper cover plate.

The utility model optimal technical scheme is: base plate is positioned at the lower side panel outside locating ring is housed, and the locating ring inboard is a ramp structure, and matches with the inclined-plane of each smooth block opposite position.

The protection switch that quantity is no less than 1 is equipped with at the locating ring top.

One of devices such as that drive unit can be selected for use is pneumatic, hydraulic pressure, vacuum, electromagnetism, hinge.

After the utility model adopted technique scheme, its advantage was:

(1) by the vertical drive smooth block of vulcanizer and the base plate folding of pattern block and band lower side panel, active force by drive unit simultaneously, drive corresponding carriage, smooth block and the open and close movement radially of pattern block do, movement travel is two rectilinear motions, moves simple and direct, accurate positioning.

When (2) effect of locating ring is to guarantee matched moulds, cooperate between each smooth block and the pattern block accurately to put in place, cooperate closely.In other words, that is to say when the synthetic monoblock type of each smooth block and pattern block, increased anchor ear one in each smooth block outside.

(3) effect of protection switch is to prevent that decorative pattern is depressed into locating ring before not having matched moulds, thereby the protection mould is not subjected to accidental injury.

The specific embodiment

As shown in Figure 2, the utility model comprises the upper cover plate 1 of being with epipleural 7, the base plate 4 of band lower side panel 6, place epipleural 7 and lower side panel 6 outsides and form the 8-12 piece pattern block 5 of a closed inner chamber with epipleural 7 and lower side panel 6, the corresponding all one by one fastening smooth block 10 that is equipped with in 8-12 piece pattern block 5 outsides, smooth block 10 outsides correspondence all one by one are connected with drive unit 2, one of devices such as that drive unit 2 can be selected for use is pneumatic, hydraulic pressure, vacuum, electromagnetism, hinge.8-12 the carriage of being made up of slide block 3 and wearing plate 9 is housed, wherein slide block 3 and corresponding all one by one fastening linking to each other of smooth block 10 tops in the upper cover plate 1.Base plate 4 is positioned at lower side panel 6 outsides locating ring 8 is housed, and locating ring 8 inboards are a ramp structure, and matches with the inclined-plane of each smooth block 10 opposite position.The protection switch 11 that quantity is no less than 1 is equipped with at locating ring 8 tops.

Motion of the present utility model can be divided into die sinking and two kinds of motions of matched moulds, below is described in detail respectively.

During the die sinking campaign, as shown in Figure 3, under the castering action of vulcanizer, smooth block 10, pattern block 5 at first separate with the base plate 4 of being with lower side panel 6.Then as shown in Figure 4, under each self-corresponding drive unit 2 drives, by each slip of self-corresponding slide block 3 on wearing plate 9, smooth block 10, pattern block 5 are all done radial motion and are separated with epipleural 7, finish the branch mould, take off the tire that from the closed inner chamber that epipleural 7, lower side panel 6 and 8-12 piece pattern block 5 form, is shaped.

During the matched moulds motion, each smooth block 10 and pattern block 5 do radial motion under the driving of each self-corresponding drive unit 2 and epipleural 7 merges.Under the effect of vulcanizer, upper cover plate 1, smooth block 10, pattern block 5 integral body of band epipleural 7 move downward and merge with the base plate 4 of lower side panel 6, finish the matched moulds motion of mould, and the state of this moment as shown in Figure 2.
