Background
When the steel sheet of the tire mold is used for vulcanizing a tire, fine pattern grooves are formed, and the firmness of the steel sheet on the mold is a key factor which restricts the service life of the tire mold. Most of the existing steel sheets are fixed by welding, pin setting, gluing and the like.
However, the above steel sheet fixing method has the following problems in practical use:
1. due to the limitation of materials and patterns of some dies, if the steel sheet is fixed in a welding and pin-down mode, a lot of workload is increased. For example, most of the current tire molds use two materials, namely steel or aluminum, and the steel sheet and the aluminum cannot be fused by common welding; the distance between the die steel sheets or between the steel sheets and other grooves is close, and no enough space is provided for the lower pin.
Meanwhile, the position of the lower pin needs to be corrected and welded after the lower pin is arranged, the time of approximately two days is needed for welding and trimming the lower pin of one common die, the time is wasted, and the working efficiency is low.
And the welding area has color difference in the repeated use process, which directly influences the beauty of the vulcanized tire.
2. For the gluing fixing mode, if the steel sheet is fixed only by gluing, the glue gradually loses the original effect along with the passage of time and the repeated use of the die.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
