Extrusion mold for non-pneumatic multi-hole hollow tire
Abstract:
The invention discloses an extrusion mold for non-pneumatic multi-hole hollow tires, which can be used for producing the hollow tires which are non-pneumatic, highly elastic and materials-saving and is characterized by consisting of the mold frame (1) and the mold core (2), with one end of the mold frame (1) connected with the extruder's feeder and the other end connected with the mold core (2); inside the mold frame (1) is provided a feeding via (3), one end of which communicates with the feed inlet of the extruder's feeder and the other end communicates with the discharge hole (4) of the mold core (2); the discharge hole (4) is provided with several mold blocks (5), which match the shape of the hollow holes in the tires and are directly or indirectly connected with the wall of the discharge hole (4) through a thin-wall connection strap (6).
