Non-inflatable hollow tire mould

An inflation-free hollow tire modeling die comprising:

• a die base, at least one die core and at least one core holder;
• wherein a front face, facing a discharge outlet of an extrusion forming machine, of the die base has a concave feeding cavity, and a bottom of the feeding cavity has a modeling cavity running through a back face of the die base;
• wherein the at least one core holder comprises an arc support or a triangular support, wherein supporting feet of the arc support or triangular support are fixed to an outer edge portion of the feeding cavity, and a top of the arc support or triangular support is located in front of the modeling cavity and outside the concave feeding cavity;
• wherein the at least one die core comprises a suspended die core whose main body is columnar, wherein the suspended die core corresponds to an inner cavity of a tire, a length direction of the suspended die core is perpendicular to the front face and the back face of the die base, a head end of the suspended die core is fixedly connected to the at least one core holder, and a tail end of the suspended die core is extended backward and positioned in the modeling cavity;
• and wherein a shape of a cross-section of the suspended die core and a relative position of the suspended die core in the modeling cavity are matched with respective internal structure and a shape of the tire, and a shape of a cross-section of the modeling cavity is matched with a contour of the tire.
