In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

The first embodiment is as follows:

as shown in fig. 1, 2 and 3, for the basic structure of the first embodiment of the present invention, a tire number machining device includes a lower side plate 1, a tire number sheet 4 and a plurality of positioning pins 2, the lower side plate 1 is a part of a tire mold, the positioning pins 2 include a pin 21 and a limiting portion 22, the limiting portion 22 is fixed on the top of the side surface of the pin 21, the bottom surface of the inner side of the lower side plate 1 is provided with a plurality of positioning pin holes 11 vertically penetrating through the lower side plate 1, the plurality of positioning pin holes 11 correspond to the plurality of positioning pins 2 one to one, and the diameter of the pin 21 is the same as the diameter of the positioning pin holes 11; the plurality of pin shafts 21 are respectively inserted into the corresponding positioning pin holes 11, the limiting parts 22 and the inner bottom surface of the lower side plate 1 respectively abut against the top surface and the bottom surface of the tire number piece 4, and the tire number piece 4 is fixed on the lower side plate 1. The number of the positioning pins 2 is two in the present embodiment, and the number of the positioning pin holes 11 is two. The positioning pin 2 can fix the tire number sheet 4 on the lower side plate 1 so as to prevent the tire number sheet 4 from being blown out by extruded air to cause the tire number position displayed on the tire side wall to be non-uniform or the finished tire has no tire number.

Specifically, the pin shaft 21 and the positioning pin hole 11 are connected by transition fit. The transition fit can be realized fixing the positioning pin 2 in the corresponding positioning pin hole 11, and the positioning pin 2 can be pulled out from the positioning pin hole 11 when the positioning pin 2 needs to be replaced.

Specifically, two locating pins 2 all are located the one side that deviates from 1 axis of lower plate 4 of child number piece. Because aerify the capsule when extruding the inside air of mould, the air that is located child embryo bottom is along the radial direction of downside board 1 lateral wall to being close to the direction removal of downside board, this embodiment sets up two locating pins 2 in the one side that child number piece 4 deviates from 1 axis of downside board for child number piece 4 is under two locating pins 2's the blockking, can't be along with the air that is extruded by aerifing the capsule removes to the direction of keeping away from 1 axis of downside board, further improves the location effect of locating pin 2 to child number piece 4.

Specifically, each pin shaft 21 is provided with a first exhaust hole 23 penetrating through the pin shaft 21 along the axis of the pin shaft 21. When the air in the capsule extrusion die is inflated, the tire number sheet 4 can cause certain obstruction to the air discharged from the lower side plate 1, so that the air pocket phenomenon is easily generated near the tire number sheet 4. In the vulcanization process, because nest air can not contact with the lower side plate 1 completely, the tire blank rubber material near the tire number piece 4 can be heated and can not flow uniformly, and then the tire blank after vulcanization molding is in a rubber shortage state. In the embodiment, the first exhaust holes 23 are formed in the pin shaft 21, so that air in the lower side plate 1 can leave the mold through the first exhaust holes 23 and the positioning pin holes 11, the possibility of air pocket phenomenon near the tire number sheet 4 is reduced, and the possibility of rubber shortage of a tire blank after vulcanization molding is reduced.

Specifically, two locating pins 2 deviate from the side evenly distributed of lower plate 1 axis along child number piece 4, have improved the efficiency that the air in lower plate 1 leaves the mould through first exhaust hole 23 and locating pin hole 11, further reduce the possibility that near child number piece 4 nest gas phenomenon produced.

Specifically, the tire number sheet 4 in this embodiment is an aluminum tire number sheet 4. The heat conductivity and ductility of aluminum are superior to those of iron, so that the aluminum tire number sheet 4 can achieve a better heat conduction effect compared with the iron tire number sheet 4, and the influence of the tire number sheet 4 on the vulcanization effect of the tire blank part nearby the aluminum tire number sheet can be reduced.

In conclusion, this embodiment is fixed No. 4 on the curb plate 1 through locating pin 2 to No. 4 is blown by the air of extruding partially, avoids the tire side wall to show that No. position is unified, or the finished product tire does not have the child number. In addition, the first exhaust holes 23 are formed in each pin shaft 21, so that air in the lower side plate 1 can leave the mold through the first exhaust holes 23 and the positioning pin holes 11, the possibility of air pocket phenomenon near the tire number piece 4 is reduced, and the possibility of rubber shortage of a tire blank after vulcanization molding is reduced. Last this embodiment sets up two locating pins 2 in the one side that child number piece 4 deviates from 1 axis of curb plate down for child number piece 4 can't be along with being removed by the direction of the air of inflating the capsule extrusion to the direction of keeping away from 1 axis of curb plate down under the blockking of two locating pins 2, has further improved locating pin 2 to the location effect of child number piece 4.
