TECHNICAL FIELD

[0001] The utility model relates to tire processing technical field, concretely is a tire mould. BACKGROUND

[0002] As an important part of the automobile, the appearance of the tire has been widely concerned, and its quality and effect directly affect the overall aesthetic of the automobile. The mainstream traditional tire decoration structure currently mainly relies on the visual level made by the change of the pattern composed of strip texture. In addition, some emerging tire decorations use high-precision carving equipment to complete the carving of small graphic units, such as complex combinations of millimeter-level small cylinders, small cones, and small snowflakes to meet the changing market demand.

[0003] With the increase of the pattern style, in order to reduce the use cost of the mould, researchers in the related field began to develop a mould technology that can replace the icon alone. For example, the patent document with the application number 201921869703.2 discloses that "the movable block is inserted into the accommodating groove of the tire mould, then the movable block is moved along the accommodating groove, the insert block at one end of the movable block is inserted into the insert slot at one end of the accommodating groove, then the jacking block is inserted into the end of the accommodating groove away from the insert block, the limiting slot and the limiting block are matched to ensure the fixation of the movable block in the accommodating groove, then the first countersunk bolt is inserted into the first countersunk hole, which can complete the fixation of the jacking block and the accommodating groove. Finally, in order to avoid loosening, the second countersunk bolt and the second countersunk hole are matched to further complete the fixation of the movable block and the tire mould. The movable block is directly engraved, which is simple to operate, and even if the engraving on the movable block is wrong, the movable block can be directly replaced, which will not affect the tire mould", however, the part of the locking structure of the above-mentioned prior art, such as the first countersunk bolt, is directly exposed in the molding space of the mould, which cannot maintain the integrity of the molding space of the mould, so there is a great limitation in the actual use.

[0033] Working principle:

[0034] Embodiment one

[0035] For the assembly operation of the mold body 1 and the assembly module 2, the specific operation is as follows:

[0036] Firstly, the assembly module 2 is assembled in the inside of the accommodation cavity 3 and forms an integral space with the inside of the mold body 1. During the assembly process of the assembly module 2 and the accommodation cavity 3, the positioning hole 6 in the inside of the assembly module 2 will be clamped and guided with the first hollow cylinder 71 in the inside of the composite positioning assembly 7, thereby reducing the assembly deviation between the assembly module 2 and the accommodation cavity 3;

[0037] Secondly, one end of the screw 81 in the inside of the composite locking assembly 8 penetrates through the countersunk hole 5 and is screw-connected to the inside of the corresponding combined threaded hole 4. The transition connecting block 83 and the accommodation slot in the inside thereof provide a structure condition for combined force application with the existing wrench, thereby limiting and locking the assembled mold body 1 and the assembly module 2, and ensuring the stability of the whole mold during subsequent use;

[0038] Third step, after the mold body 1 and the assembled module 2 are assembled stably, to avoid the interference of the transition connecting block 83, the transition connecting block 83 can be milled and eliminated by using the existing data milling machine, then the top surface of the sealing screw block 82 is coplanar with the top surface of the assembled module 2 and the inner wall of the corresponding position of the mold body 1, the complete forming space inside the mold body 1 is maintained, the icon groove 9 on the top surface of the assembled module 2 provides the unique pattern mark structure condition after the tire is formed, and according to the actual demand, the number of the counter sunk hole 5, the number of the positioning hole 6, the number of the composite positioning assembly 7 and the number of the composite locking assembly 8 can be two or more than two;

[0039] Fourth step,

[0040] When the assembled module 2 needs to be replaced, only the same displacement groove as the transition connecting block 83 is milled on the top surface of the sealing screw block 82 by using the existing data milling machine, then the existing wrench is combined to apply force and screw out the screw 81, and then another assembled module 2 is replaced and the first step to the third step are operated one by one.

[0041] Example two

[0042] For the combined use of the mold body 1 and the assembled module 2, the vibration suffered during use can be damped and buffered by the damping block 74 inside the composite positioning assembly 7 cooperating with the first hollow cylinder 71, the second hollow cylinder 72 reciprocating moving in the double direction guided by the auxiliary guide rod 75 and the buffer spring 73 reciprocating deforming, then the stability of the screw 81 and the counter sunk hole 5 is maintained, and then the stability of the assembled use of the mold body 1 and the assembled module 2 is ensured.
