To solve the above-mentioned problems, the present invention provides a kind of non-inflatable tyre centrifugal casting moulds of cellular sidewall support
Tool, by the mold improve can Quick pouring there is the tire of shock-absorbing function and can realize the abundant knot of tyre and rim
It closes, and the centrifugal casting-mould can make tire honeycomb fashion sidewall support performance excellent.
In order to achieve the above object, the technical solution adopted by the present invention is：
The non-inflatable tyre centrifugal casting-mould of cellular sidewall support, includes the epipleural and lower side panel of coaxial rotating,
Radially it is disposed with concentric wheel rim, edge cylinder and pattern ring between the epipleural and lower side panel from inside to outside along tire；
By being formed along the radial multilayer edge column circle from inside to outside of tire, every layer of edge column circle is made of the edge cylinder multiple cylinders；Institute
The axis of cylinder is stated perpendicular to epipleural and lower side panel, and the cylinder is along the circumferential uniformly arrangement of tire；The epipleural
Outer concentric is provided with cast hopper, and the cast hopper is provided centrally with sprue；The edge of rim is corresponded on the epipleural
It is circumferentially provided with multiple feed inlets.
As advanced optimizing for the present invention, the basal diameter of the cylinder radially drops successively from inside to outside along tire
It is low.
As advanced optimizing for the present invention, the epipleural and the lower side panel are coaxially fixed by hexagon socket head cap screw.
Compared with prior art, the advantages and positive effects of the present invention are：
1, there is damping using casting equipment Quick pouring while mold of the invention can be centrifuged by centrifugation apparatus
The tire of function；
2, the design of edge cylinder can ensure that the tire of centrifugal casting has cellular sidewall, can be by tyre load by outer
Inwardly transmit successively, it is uniformly discrete, to significantly improve the load-carrying properties of tire, improve the comfort of tire and anti-tie；
3, mold of the invention can substantially reduce the appearance of stomata in casting process, and cast effect is good；
4, mold of the invention can realize the cast of non-inflatable tyre under the premise of not destroying wheel rim, and can realize wheel
The abundant combination of tire and wheel rim.

Specific implementation mode
In the following, the present invention is specifically described by illustrative embodiment.It should be appreciated, however, that not into one
In the case of step narration, element, structure and features in an embodiment can also be advantageously incorporated into other embodiment
In.
In the description of the present invention, it should be noted that the traveling axis of tire-mold generation tire is axial in attached drawing 1,
Circumferencial direction is circumferential, is radial along the direction of radius；And be outside along the increased direction of radius, it is along the direction that radius reduces
Inwardly.The orientation or positional relationship of the instructions such as term "inner", "outside", "upper", "lower", "front", "rear" is based on attached shown in FIG. 1
Position relationship is merely for convenience of description of the present invention and simplification of the description, and does not indicate or imply the indicated device or element must
There must be specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
Referring to Fig. 1, it is the side view of the non-inflatable tyre centrifugal casting-mould of the present invention in conjunction with Fig. 2 and Fig. 3, Fig. 1 and bows
View；Fig. 2 and Fig. 3 is respectively A-A sectional views and B-B sectional views.As shown in Figure 1, the non-inflatable tyre of cellular sidewall support
Centrifugal casting-mould includes the epipleural 1 and lower side panel 2 of coaxial rotating, along tire diameter between the epipleural 1 and lower side panel 2
To being disposed with concentric wheel rim 3, edge cylinder 4 and pattern ring 5 from inside to outside；The edge cylinder 4 is by radial by interior along tire
Outside multilayer edge column circle 41 forms, and every layer of edge column circle 41 is made of multiple cylinders 411；The axis of the cylinder 411
