Description
Technical field
The utility model relates to a kind of mould, is specifically related to the rim strip production mould of the rim strip that a kind of production uses on tire.
Background technology
Rim strip is claimed lining band, press strip again.Refer to be used to protect the inner tube of a tyre the endless rubber belt that the face of closing does not receive the wheel rim wearing and tearing.It is loaded between the inner tube of a tyre and the wheel rim, and the center is thicker, and two edges are gradually thin from inside to outside.The rim strip outer surface has a center line, the match line when doing to install.Also have a hole on the center line, supply inner tube valve to pass.Rim strip is less demanding to the physical and mechanical properties of sizing material, but good aging properties should be arranged.Be bonded to the tubeless tyre and the extra-low pressure tire that is bonded to the special construction wheel rim of deep-well rim,, do not need rim strip because of closing closely.The annulus rubber cincture that the definite shape section is arranged.There is a circular hole can let inner tube valve pass above.Be enclosed within on the wheel rim in order to protect the inner tube of a tyre not receive the wearing and tearing of wheel rim and cover tire tyre bead.According to section, can divide two kinds of matrix and flat patterns.The former assembling is convenient, and riding position also is prone to correct.Be widely used in the automobile air core tyre.
The rim strip device is mainly used in the protection tube and is not galled by wheel rim between the wheel rim and the inner tube of a tyre, and the protection inner tube of a tyre can be not bad by cover tire toe mouth and wheel rim folder.Present rim strip all is to be processed by single common colloid sizing material, produces the mould of rim strip and structurally is made up of patrix, middle mould, counterdie, and patrix is an inverted cone-shaped, and middle mould is circular, and counterdie is coniform, and circle is provided with raw material tank around the upper end of counterdie.During production it is installed on the vulcanizer, the circle raw material tank is loaded onto the sizing material bar around the upper end of counterdie, under the conditions of vulcanization that is provided with, makes patrix, middle mould, counterdie be pressed into one, produces rim strip.Such planform mould causes the sizing material bar not flow up and down simultaneously, but is full of a die cavity earlier, then is full of the another side die cavity again, and the flow direction of sizing material is uncertain, so can not grow the rim strip of two sizing material structures; In addition, present rim strip side face edge is thinner, is unfavorable for protecting the inner tube of a tyre.
Therefore produce a kind of simple in structurely, easy to use, firm, the rational in infrastructure rim strip closely of the product of producing production mould has vast market prospect.
The utility model content
To the deficiency of prior art, the utility model provides a kind of rim strip production mould simple in structure, easy to operate, rational in infrastructure.
The technical scheme of the utility model is such realization: a kind of rim strip production mould; Comprising that length direction patrix, top that the bottom has a semi-annular shape breach have the rectangle counterdie of semi-circular shape breach and is arranged on outer wall middle part between the upper die and lower die is provided with mould in groove circular; Mould is made up of mould in the mould in the left side and the right side in described; In a left side, be provided with modular ring in the left side between mould and the patrix, in the right side, be provided with modular ring in the right side between mould and the patrix.
The circular module that mould is made up of big end of taper and cylindrical small end in the described left side; The small end face of Zuo Zhongmo is provided with convexity; In the described right side mould by big end of taper and cylindrical small end form circular; The small end face of mould is provided with groove in the right side, and mould interconnects through protruding and groove in the Zuo Zhongmo and the right side.
In the described right side in modular ring, the left side ring wall of modular ring be the conical surface.
The utlity model has following good effect: this product structure is simple, when producing two sizing material rim strip, this product is installed on the vulcanizer; In a left side, twine the sizing material bar of two colloid structures in the mould and the right side on the mould, under the conditions of vulcanization that is provided with, make patrix and counterdie simultaneously to middle mould extruding; Simultaneously; In the right side in modular ring, the left side under the effect of modular ring the sizing material bar under the effect of external pressure, in die cavity, flow in order, can produce rim strip, the rim strip marginal portion of production is effectively strengthened; Double-layered edges helps protecting air tube.

The specific embodiment
Like Fig. 1-shown in Figure 8; A kind of rim strip production mould; Comprise length direction patrix 1, top that the bottom has a semi-annular shape breach have the rectangle counterdie 2 of semi-circular shape breach and be arranged on patrix 1 and counterdie 2 between the outer wall middle part mould in groove circular is set; Mould is made up of mould 3 in the mould in the left side 4 and the right side in described, in a left side, is provided with modular ring 6 in the left side between mould 4 and the patrix 1, in the right side, is provided with modular ring 5 in the right side between mould 3 and the patrix 1.
The circular module that mould 4 is made up of big end of taper and cylindrical small end in the described left side; The small end face of mould 4 is provided with protruding 8 in the left side; In the described right side mould 3 by big end of taper and cylindrical small end form circular; The small end face of mould 3 is provided with groove 7 in the right side, in the left side in mould 4 and the right side mould 3 interconnect with groove 7 through protruding 8.In the described right side in modular ring 5, the left side ring wall of modular ring 6 be the conical surface.
This product structure is simple, when producing two sizing material rim strip, this product is installed on the vulcanizer; In a left side, twine the sizing material bar of two colloid structures in the mould and the right side on the mould, under the conditions of vulcanization that is provided with, make patrix and counterdie simultaneously to middle mould extruding; Simultaneously, in the right side in modular ring, the left side under the effect of modular ring the sizing material bar under the effect of external pressure, in die cavity, flow in order, can produce rim strip; The rim strip marginal portion that produces is effectively strengthened, and double-layered edges helps protecting air tube.The sized of mould can be processed series of products according to the dimensional requirement of tire flap.
This product cost is low, high efficiency, and the product strength of production is high, and is rational in infrastructure tight, brought profit to enterprise, has vast market prospect.
