Embodiment 1

[0048] figure 1 A partial cross-sectional view of the tire mold side plate 100 provided for this embodiment; figure 2 for figure 1 Schematic diagram of the overall structure in the middle II direction. Please refer to figure 1 and figure 2 , in this embodiment, the tire mold side plate 100 includes a side plate body 110 , a steel ring 130 connected to the side plate body 110 , and a plurality of side plate segments 120 arranged at intervals along the circumference of the side plate body 110 .

[0049] The tire mold side plate 100 provided in this embodiment is further described below:

[0050] image 3 A partial sectional view of the side plate body 110 in the tire mold side plate 100 provided in this embodiment. Please refer to image 3 , In this embodiment, the side plate body 110 is in the shape of a ring. The side plate body 110 has a bottom surface 111a, a first receiving surface 111b opposite to the bottom surface 111a for receiving the side plate fan 120 and a...

Embodiment 2

[0066] This embodiment also provides a tire mold side plate 100, which is basically the same as that of Embodiment 1, except that the way of adjusting the position of the side plate segment 120 in the radial direction is different.

[0067] Figure 8 A partial sectional view of the tire mold side plate 100 provided for this embodiment. Please refer to Figure 8Specifically, the tire mold side plate 100 is provided with a first gear 151 and a second gear 152 meshing with each other. The first gear 151 is a bevel gear, which is rotatably connected with the side plate body 110 along the radial direction of the side plate body 110 . The second gear 152 is a bevel gear arranged coaxially with the side plate body 110 . When the first gear 151 rotates, the second gear 152 is driven to rotate around the axis of the side plate body 110 . The second gear 152 is arranged between the side plate body 110 and the side plate fan 120 , and its end opposite to the gear teeth is provided wit...

Abstract

The invention relates to tire manufacturing, and aims to improve the problems of rubber burrs and rubber edge are occurred on the side surface after a tire is vulcanized in a prior art. The inventionprovides the tire mold side plate and the tire mold. Due to the tire mold side plate and the tire mold are provided with a plurality of side plate blades in the circumferential direction of a side plate body, and gaps between each adjacent side plate blade served as exhaust channels to discharge air in the tire mold out of the mold, so that the problem that the rubber burr and the rubber edges occurred on the side surface after the tire is vulcanized caused by rubber materials flow out of the exhaust holes due to the exhaust holes arranged in the tire are avoided.

Description

technical field [0001] The invention relates to the technical 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 rubber is expelled from the air holes, and many rubber hairs are formed 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 cle...
