Embodiment 3

[0073] Figure 14 A partial cross-sectional structural schematic diagram of the tire mold 010 provided in this embodiment. The tire mold 010 includes an upper cover 011 and a base 012 oppositely arranged. The two sets of tire mold side panels 100 described in Embodiment 1 are fixedly connected to the lower surface of the upper cover 011 and the upper surface of the base 012 respectively. The tire mold 010 also includes a plurality of pattern blocks 013 arranged radially outside the tire mold side plate 100, and a guide ring mechanism 014 for controlling the closure or opening of the pattern blocks 013 during mold opening and closing. Figure 14 In this case, the tire mold 010 is in a mold clamping state, and the pattern blocks 013 and two sets of tire mold side plates 100 together form a mold cavity 015 . During the working process of the tire mold 010, the gas in the mold cavity 015 enters the exhaust groove 131b through the exhaust gap 131a, collects into the circumferenti...

Abstract

The invention relates to the field of tire manufacturing, aims to improve the problem of generation of rubber burrs and flanges on vulcanized tire side surfaces in the prior art, and provides a tire mold side plate and a tire mold. The tire mold side plate comprises a side plate body, and multiple side plate pieces arranged on the side plate body in the peripheral direction at intervals; exhaust channels are formed between the adjacent side plate pieces; during working, gas from a molding cavity of the mold is exhausted through the exhaust channels; and an exhaust hole has no need to be provided for exhausting the gas, so that the problem of generation of the rubber burrs on the vulcanized tire side surfaces is prevented. The side plate pieces and the side plate body movably cooperate in the peripheral direction, so that the exhaust channels are distributed more uniformly, the gas is exhausted more sufficiently, and the gas exhausting speed is higher.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a tire mold side plate and a tire mold. Background technique [0002] When the tire is vulcanized, it is necessary to discharge the gas between the side plate and the green tire during the closing process of the active mold. The material is discharged from the air hole, forming a lot of rubber wool on the side of the tire. There are still the following problems in the side plate with the air vent: 1. The vulcanized tire is not beautiful. If the rubber hair needs to be trimmed before the tire leaves the factory, the labor cost of the tire factory will also be increased; 2. The trimmed rubber hair can only It is treated as waste, which wastes raw materials, and the natural degradation of rubber wool is difficult, polluting the environment; 3. The vent hole is easy to block, in order to ensure the normal vulcanization, it is necessary to stop production regularly to clear the vent...
