[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0005] A movable type block structure for a tire mold that is easy to assemble and disassemble. The movable type block is mounted on a side panel of the tire mold. The movable type block includes a movable type block body. The angle between the bottom and side surfaces of the movable type block body is a right angle, and the top surface of the movable type block body is an inclined surface. A step is provided on the outer side of the upper end of the movable type block body. The top surface of the step has the same inclination as the top surface of the movable type block body, and the step is integrally formed with the movable type block body.

[0006] Preferably, the height of the step is a, and the value of a is 3mm-5mm; the angle between the upper end of the movable type block body and the contact surface of the side plate is b, and the value of b is 5°-8°; the bottom of the step is provided with a chamfer c, and the value of c is R0.5-R1; the bottom of the movable type block body is provided with a chamfer d, and the value of d is R0.5-R1.

[0007] Preferably, the movable type block body is engraved with trademarks, patterns, high-voltage load parameters and certification marks.

[0008] Preferably, a screw mounting hole is provided inside the movable type block body.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention reduces the resistance during disassembly and assembly by changing the contact area between the type block and the side plate of the mold, avoids deformation of the type block, and extends the service life of the type block; at the same time, chamfers are provided at the bottom of the step and the bottom of the type block body to avoid scratches on the side plate grooves due to the sharp edges of the type block during installation.

[0017] The following describes the invention of the present invention in detail by way of examples in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Example

[0018] like Figures 2 to 4 As shown, the present invention discloses a movable type block structure for tire molds that is easily disassembled and assembled. The movable type block 1 is mounted on the side panel 2 of the tire mold and includes a block body 11 engraved with a trademark, pattern, high-voltage load parameters, and certification marks. The bottom and side surfaces of the block body 11 form a right angle, and the top surface of the block body 11 is inclined. A step 12 is provided on the outer side of the upper end of the block body 11. The top surface of the step 12 has the same inclination as the top surface of the block body 11 and is integrally formed with the block body 11. Screw mounting holes 13 are provided within the block body 11. This utility model reduces the contact area between the block 1 and the side panel 2, reduces resistance during assembly and disassembly, prevents deformation of the block 1, and extends the service life of the block 1.

[0019] Furthermore, in this embodiment, the height of the step 12 is a, and the value of a is 3 mm; the angle between the upper end of the movable block body 11 and the contact surface of the side panel 2 is b, and the value of b is 5°; the bottom of the step 12 is provided with a chamfer c, and the value of c is R0.5; the bottom of the movable block body 11 is provided with a chamfer d, and the value of d is R0.5. By providing chamfers at the bottom of the step 12 and the bottom of the movable block body 11, it is avoided that the sharp edge of the movable block 1 may scratch the groove of the side panel 2 during installation.

[0020] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and application concept of the present invention, should be covered by the protection scope of the present invention.
