Detailed Description
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 4, a die cavity curb plate, including curb plate body 1, be equipped with exhaust line 2 and outside intercommunication on the die cavity face of the inboard side of curb plate body 1, exhaust line 2 includes a plurality of, and the preferred circumference equipartition of a plurality of exhaust lines 2 is on the die cavity face of the inboard side of curb plate body 1, and exhaust line 2 is along the gradual change of outside extension direction size, and the gradual change of size is established to the degree of depth gradual change, and/or, the width gradual change, preferably: the width X of the exhaust line 2 is set to be 0.5mm-1.5mm, the depth Y of the exhaust line 2 is set to be 0.6mm-1.5mm, and different depths, widths and angles of the exhaust line 2 are designed according to different tire factories, different vulcanization environments and different rubber compound formulas.
Specifically, two side fitting surfaces of 2 intercommunication curb plate bodies 1 of exhaust line, 1 both sides of curb plate body are equipped with a plurality of curb plate decorative pattern piece fitting surface air lines 6 and curb plate steel ring fitting surface air line 7 and a plurality of exhaust line 2 and correspond the intercommunication, and when the exhaust line 2 extended to both sides side fitting surface, 2 degree of depth deepening gradually of exhaust line, and/or, 2 width widen gradually of exhaust line, as the embodiment of a preferred: the size X of the exhaust line 2 in the middle of the side plate body 1 is 0.5mm/Y is 0.6mm, the size X of the exhaust line 2 on two side edges of the side plate body 1 is 1.5mm/Y is 1.5mm, and the size of the exhaust line 2 smoothly transits from the middle of the side plate body 1 to the two side edges of the side plate.
The structure fully combines the characteristics of the tire blank when the tire blank is contacted with the inner side cavity surface of the side plate body 1 in the vulcanization process, the size of the exhaust line 2 firstly contacted with the tire blank is gradually increased towards the size of the exhaust line 2 secondly contacted with the tire blank, and therefore the exhaust effect of the tire side is improved.
As another preferred embodiment, the side plate body 1 of the utility model can be further provided with upper part exhaust holes, the exhaust line 2 with gradually changed size is communicated with the exhaust holes, the number of the original exhaust holes is reduced by means of the exhaust line 2, and rubber wool is reduced or omitted, so that the tire appearance is cleaner and more beautiful, the problem of exhaust hole blockage is also greatly reduced, the vulcanization efficiency of the tire is improved, the exhaust holes are further reduced, and the processing difficulty and the processing cost of a mold are also reduced.
Because the inner side cavity surface of most side plate bodies 1 is provided with a plurality of image-text grooves 5, in order to avoid the phenomenon that the bottom of the image-text grooves 5 lacks glue due to unsmooth exhaust, air holes are required to be added at the bottom of the image-text grooves 5 for exhaust, as shown in figure 7, because each corner part with irregular pictures and texts generally needs to be added with air holes, the processing cost and the processing difficulty of the die are greatly increased, in order to reduce the number of the air holes, the bottom of each picture and text groove 5 of the utility model is provided with a picture and text exhaust hole 3 and a picture and text exhaust line 4, as shown in fig. 5 and 6, the text exhaust hole 3 only needs to be arranged at the corner of the text, then the image-text exhaust line 4 is communicated with the image-text exhaust holes 3 to reduce the number of air holes, and the comparison shows that the number of the image-text exhaust holes is reduced by 8, so that the cost and the difficulty of mold processing are greatly increased.
The specific exhaust principle is as follows:
when the tire is vulcanized, under the action of the internal pressure of the bladder, gas between the mold and the tire blank enters the two matching surface exhaust lines 2 through the cavity surface exhaust lines 2 on the inner side of the side plate body 1, and is exhausted out of the mold. As shown in fig. 8, the specific gas flow directions are: the gas in the mold cavity → the gas discharge line of the cavity surface on the inner side of the side plate body 1 2 → the gas discharge line of the mating surface 2 → outside the mold.
It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should also be understood that various alterations, modifications and/or variations can be made to the present invention by those skilled in the art after reading the technical content of the present invention, and all such equivalents fall within the protective scope defined by the claims of the present application.
