Abstract
The utility model discloses a mould for producing a double-sizing cushion belt, which comprises an upper mould, a middle mould and a lower mould. The mould is characterized in that the upper mould is of a rectangular shape, wherein the lower part of the upper mould is provided with a semicirque notch; the middle mould is of a circular shape; the middle of the outer wall of the middle mould is provided with a groove; the lower mould is of a rectangular shape, wherein the upper part of the lower mould is provided with a semicirque notch; the semicirque notches of the upper mould and the lower mould correspondingly enclose a circle and are matched with the shape of the middle mould; under the set sulfuration condition, the upper mould and the lower mould simultaneously extrude towards the middle mould; and sizing strips flow in a mould chamber in order under the action of external pressure and can manufacture the double-sizing cushion belt.
Description
Technical field:
The utility model relates to a kind of pair of sizing material rim strip production mould.
Background technology:
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 made 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 produce the rim strip of two sizing material structures.
The utility model content:
The purpose of this utility model provides a kind of two sizing material rim strip production moulds that can produce two colloid structure rim strips.
In order to realize above-mentioned purpose, the utility model comprises: patrix, middle mould, counterdie, patrix is a rectangular shape, its middle and lower part has the semi-annular shape breach, middle mould is circular, and its outer wall middle part is provided with groove, and counterdie is a rectangular shape, its middle and upper part has the semi-annular shape breach, and patrix is corresponding with the semi-annular shape breach of counterdie to surround circle and be complementary with middle mould shape.
Like this, when producing two sizing material rim strip, it is installed on the vulcanizer, the sizing material bar of two colloid structures in the groove of middle mould, twining, under the conditions of vulcanization that is provided with, make patrix and counterdie simultaneously to middle mould extruding, the sizing material bar flows in die cavity under the effect of external pressure in order, can produce two sizing material structure rim strips.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A profile of the utility model structural representation.
The specific embodiment:
As seen from Figure 1, Figure 2, the utility model comprises: comprising: patrix 1, middle mould 2, counterdie 3.Patrix 1 is a rectangular shape, and its middle and lower part has the semi-annular shape breach, breach middle part projection.Middle mould 2 is circular, and its outer wall middle part is provided with groove.Counterdie 3 is a rectangular shape, and its middle and upper part has the semi-annular shape breach, breach middle part projection.Patrix is corresponding with the semi-annular shape breach of counterdie to surround circle and is complementary with middle mould shape, and patrix 1, middle mould 2, counterdie 3 are trapped among the inner space that forms together and constitute die cavity 4, and the shape of die cavity is the shape of two sizing material rim strips.Mould should adopt intensity height, corrosion-resistant, resistant to elevated temperatures alloy material to be processed into, and the big I of the specification of mould is made series of products according to the dimensional requirement of tire flap.
