[0002] With the development of automobile industry and tire industry, automobile tire molds have developed rapidly, among which flexible molds are widely used. Flexible molds are a kind of molds used for vulcanization molding of various tires. They are composed of pattern rings, mold sleeves, upper and lower side panels. Their structure is relatively complex and heavy. In addition, in order to indicate the manufacturing information during the mold manufacturing process, it is also necessary to engrave the mold so that it can be directly imprinted on the tire surface during casting.

The tread blocks are contacted and driven to move from both sides of the tread block, and the rotation of the clamping block is used to adapt to the position adjustment during the clamping process. Finally, the tread blocks are clamped synchronously from both sides to achieve stable clamping of the tread blocks. However, tire molds are usually composed of upper and lower side panels. In the above case, the design of clamping blocks on both sides can clamp from both ends, but there is a lack of clamping pressure between the upper and lower side panels, which is prone to seams and the positioning is not accurate enough.

Specifically, in order to clamp the mold and keep the upper and lower side plates of the mold clamped, clamps 1106 are installed at both ends of the vertical axis 1105. The angle of the clamp arm 1104 can be adjusted by rotating the shaft sleeve 1103, and the clamp 1106 is put on the mold. Then, the adjusting bolt 1109 on the clamp 1106 can be adjusted to push the clamp 1108 to move, and the clamp 1108 can be tightly attached to the mold.

[0036] Embodiment 2

[0037] Reference Figure 1 , Figure 2 , Figure 3On the basis of the first embodiment, a butterfly clamp 1118 is further installed on the ear plate 1102, and the butterfly clamp 1118 is tightly attached to the arc surface of the ear plate 1102. A screw hole is also opened on the side of the ear plate 1102, and a fixing screw 1119 is installed on the butterfly clamp 1118, and the fixing screw 1119 cooperates with the screw hole. Specifically, in order to facilitate the initial clamping and limiting of the mold, when the two pedestals 1101 are close to each other, the two butterfly clamps 1118 can be pushed to fit on both ends of the mold, and the ear plate 1102 is divided into two parts, the upper and lower parts, and the butterfly clamp 1118 is also divided into two parts, which can clamp the upper and lower side plates of the mold respectively, which is relatively firm.

[0038] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0039] The implementation principle of the lettering device for processing the side plate of a car tire mold according to the embodiment of the present invention is as follows: when working, the upper and lower side surfaces of the mold can be butt-jointed and spliced ​​together, and then the spliced ​​mold is placed between two pedestals 1101, and then the servo motor 1203 is started to control the rotation of the driving disk 1204. When the driving disk 1204 rotates, the connecting rod 1205 arranged at its end will follow and pull the bearing platforms 1201 on both sides to slide on the guide rail 1202. At this time, the pedestal 1101 installed on the bearing platform 1201 will follow the sliding to approach and clamp the mold, and a butterfly clamping block 1118 is also installed on the ear plate 1102 of the pedestal 1101. The butterfly clamping block 1118 is divided into upper and lower parts, which can clamp the upper and lower side plates of the mold respectively, and is relatively firm.

[0040] In order to clamp the upper and lower side plates of the mold and keep them close, clamps 1106 are installed at the upper and lower ends of the vertical shaft 1105. The angle of the clamp arm 1104 can be adjusted by rotating the shaft sleeve 1103, and the clamp 1106 is put on the mold. Then, the adjusting bolt 1109 on the clamp 1106 can be adjusted to push the clamp 1108 to move, and the clamp 1108 can be pressed against the mold. Through the squeezing and clamping of the upper and lower clamps 1108, the upper and lower side plates of the mold can be fixed together and kept stable, so that the overall continuity can be maintained during the subsequent engraving of words and patterns. In order to adjust the clamp arm 11 04 can limit the angle. After adjusting the angle of the clamping arm 1104, the extrusion bolt 1112 can be tightened. The extrusion bolt 1112 can push the sleeve 1113 and the pressure ball 1114 to slide downward. When the pressure ball 1114 slides down, the four limiting balls 1115 can be squeezed and pushed to slide into the corresponding sliding cavity until they are matched with the limiting groove 1116 on the inner wall of the roller 1110, thereby limiting the free rotation of the sleeve 1103, which is convenient for fixing the clamping arm 1104. After fixing the mold, the engraving machine 205 can be started to program the mold according to the preset program.
