The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
Cooperate shown in Fig. 1 to Fig. 4 A, Pneumatic tire die structure of the present invention is that die ontology 1 and tire lip ring 2 are cut apart, and mould is designed to separate type by integral type.
Embodiment 1, and shown in Fig. 2,2A, tire lip ring 2 and die ontology 1 vertical cut-off rule are provided in a side of the tire lip 3 of tire, and the inner of this vertical cut-off rule outwards is connecting to the tire lip of inclination angle, and this inclined angle alpha is 0 °-45 °; The horizontal partition line is to cut apart from the water-proof wire below in addition, and split thickness is A, and A thickness is set between mould mo(u)ld top half or the mo(u)ld bottom half thickness 1/8-1/2.Be provided with air discharge duct 4 in tire lip ring 2 and the junction that die ontology 1 forms the inclination angle, the initiating terminal of this air discharge duct 4 is the places, the inner at vertical cut-off rule, and its length B is 2mm-15mm, be preferably 5mm-10mm, and the depth H of air discharge duct is 0.2mm-0.8mm.The mould structure of this separate type can make mould have certain air guide performance at the tire lip of tire, thereby has improved bad order phenomenons such as local injustice of tire tire lip and tire lip bubble.
Embodiment 2, shown in Fig. 3,3A, mould tire lip is cut apart from tire lip toe position, be tire lip 3 belows that tire lip ring 2 and die ontology 1 vertical cut-off rule are provided in a side of tire, the inner of this vertical cut-off rule outwards is connecting to tire lip toe 5 of inclined angle alpha, this inclined angle alpha is 0 °-45 °, is preferably 5 °-20 °; The thickness A at these tire lip ring 2 middle parts is the 1/8-1/2 of mould mo(u)ld top half or mo(u)ld bottom half interior thickness in addition.Form between the junction of inclined angle alpha and tire lip ring 2 and the die ontology 1 vertical cut-off rule at tire lip ring 2 and die ontology 1 and to be provided with air discharge duct 4 ', the initiating terminal of this air discharge duct 4 ' is to be the 2mm-15mm place apart from tire lip toe 5 size C, be preferably 5mm-8mm, and the depth H of air discharge duct 4 ' is 0.2mm-0.8mm.This kind mode is implemented the back has further improvement to local injustice of its tire lip and tire lip bubble bad phenomenon in tire production process.
Embodiment 3, shown in Fig. 4,4A, mould tire lip is cut apart from tire lip toe position, be tire lip 3 belows that tire lip ring 2 and die ontology 1 vertical cut-off rule are provided in a side of tire, the inner of this vertical cut-off rule outwards is connecting to tire lip toe 5 of inclined angle alpha, and this inclined angle alpha is 0 °-45 °, is preferably 5 °-20 °, apart from tire lip toe 5 dimension D is the inner for vertical cut-off rule, 2mm-15mm place, and the thickness A at this tire lip ring middle part is the 1/8-1/2 of mould mo(u)ld top half or mo(u)ld bottom half interior thickness in addition.Tire lip ring 2 and die ontology 1 vertical cut-off rule place are provided with the gap 6 of hollow in addition, and these gap 6 height H are 0.2mm-3mm.Be the contact position at inclination angle at tire lip ring 2 and die ontology 1, the surface of the two is the design of roller line, and wholecircle week equidistantly arranges, roller line number per inch is between 10 orders-40 order, be preferably per inch between 25 orders-35 order, the degree of depth is 0.01mm-0.3mm, is preferably 0.05mm-0.15mm.Tire lip ring 2 and die ontology 1 adopt the setting in gap 6 of hollow and the design of roller line, can increase its air guide performance, and rubber mobility is good, and it is remarkable to make that tire improves effect to the local injustice of its tire lip and tire lip bubble bad phenomenon in process of production.
