[0003] In the current tire mold industry, the side plate is mostly designed as an integral structure. When vulcanizing different tires and needing to replace the side plate pattern, the whole side plate must be replaced integrally, which is inconvenient to operate; and when the side plate pattern is damaged, the whole side plate needs to be sent for repair. When the damage is serious, the whole side plate needs to be scrapped, all of which affect the economy of the side plate.

[0004] In view of the above problems, the utility model designs and manufactures a side plate and a tire mold to overcome the above defects. Summary of the Utility Model

[0029] For the convenience of those skilled in the art to understand, the present utility model will be further described below with reference to the accompanying drawings.

[0030] As Figures 1 to 4 shown, a side plate includes a side plate body 1. A ring groove is provided at the outer peripheral position of the upper end surface of the side plate body 1. A plurality of arc blocks 2 are detachably installed in the ring groove through a connecting structure. Preferably, 4 - 16 blocks are evenly distributed in a circumferential direction. The plurality of arc blocks 2 can be spliced into a ring, so as to jointly form the original side plate structure with the side plate body 1. Specifically, the connecting structure connects the arc block 2 to the side plate body 1 from the outside of the arc block 2 along the radial direction of the side plate. When it is necessary to disassemble and assemble the arc block 2, only disassembly and assembly need to be carried out from the side, without completely disassembling the side plate like the traditional structure and then disassembling the relevant treaded connecting blocks from the back. Therefore, the operation is more convenient.

[0031] Specifically, a radially penetrating hole is provided on the arc block 2, and a radially connecting hole is provided on the side plate body 1. The connecting structure connects the arc block 2 and the side plate body 1 through the radially penetrating hole and the radially connecting hole. The connecting structure should extend into the radially penetrating hole to avoid interference when cooperating with the tread block 10.

[0032] When the tread on one of the arc blocks 2 is damaged, rapid replacement can be realized through the above structure, and the processing and maintenance cycle of a single arc block 2 is short and the cost is low.

[0033] Embodiment 1:

[0034] As Figure 1 shown, the connecting structure is set as a screw 6, and the screw 6 can pass through the radially penetrating hole and be screwed with the radially connecting hole.

[0035] Embodiment 2:

[0036] As Figure 2 、 Figure 3 shown, the connecting structure includes a screw 6 and an expansion element 7. The expansion element 7 can be installed in the radially connecting hole, and the screw 6 can pass through the radially penetrating hole and cooperate with the expansion element 7 in the radially connecting hole. When the screw 6 is screwed, the expansion element 7 in the radially connecting hole can expand and tighten the radially connecting hole.

[0037] The expansion element 7 is preferably configured as an expansion sleeve, and the expansion sleeve is preferably configured as a high temperature resistant silicone rubber material. In this embodiment, the arc block 2 is firmly connected to the side plate body 1 through the volume expansion of the expansion sleeve, thereby avoiding the influence of deformation on the cavity curve during rigid connection.

[0038] Embodiment three:

[0039] like Figure 4 As shown, the connection structure includes a locking pin and a connection sleeve 8, one end of the connection sleeve 8 is located in the radial through hole, and the other end of the connection sleeve 8 is located in the radial connection hole. A plurality of balls 9 are evenly distributed on the circumference of the side wall of the connection sleeve 8 located in the radial connection hole. The balls 9 have a certain movable distance in the radial direction of the connection sleeve 8, but cannot be separated from the side wall of the connection sleeve 8;

[0040] The locking pin can be screwed with the connecting sleeve 8 in the radial through hole. When the end of the locking pin is inserted into the position of the ball 9, the locking pin can squeeze the ball 9 and make the ball 9 abut against the side wall of the radial connecting hole. The front end of the locking pin is preferably set as a guide taper slope, so as to ensure that the squeezing of the ball 9 is a gradual process and ensure a suitable tightening force for the ball 9. The radial connecting hole is preferably set as a step hole, and the ball 9 can cooperate with the step surface of the step hole, that is, the ball 9 can abut on the step surface. At this time, the step surface can limit the movement of the ball along the axial direction of the radial connecting hole. This method is different from limiting by the force of squeezing the ball 9 and the side wall of the radial connecting hole, and avoids the influence of rigid extrusion deformation on the cavity curve.

[0041] In the above embodiments, the side panel body 1 and the arc block 2 are also connected by a positioning pin 4, one end of the positioning pin 4 is inserted into the side panel body 1, and the other end of the positioning pin 4 is inserted into the arc block 2, thereby further improving the matching accuracy between the side panel body 1 and the arc block 2.

[0042] The arc block 2 is preferably provided with a plurality of exhaust holes 3, one side of the vulcanization cavity surface of the arc block 2 is connected to the exhaust holes 3, and the side of the arc block 2 facing away from the vulcanization cavity is provided with an exhaust groove 5 connected to the outside, and the exhaust holes 3 are connected to the exhaust groove 5 to facilitate exhaust during product vulcanization.

[0043] It is preferred that lifting holes are provided on the arc block 2 , and the number and positions of the lifting holes can be reasonably set according to the size and weight of the arc block 2 .

[0044] like Figure 5 As shown, the utility model also provides a tire mold, which includes the above-mentioned side plate.
