[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] Please refer to Figures 1-3 This utility model provides a tire mold movable block, including: mold side plate 1 and movable block 2.

[0037] The mold side plate 1 has an installation groove 11, in which the movable type block 2 is detachably installed. The bottom of the movable type block 2 has three discontinuous movable type block bottom surfaces 21, which are flat. The three movable type block bottom surfaces 21 are arranged radially in a stepped shape, with a height difference between adjacent movable type block bottom surfaces 21. The distance between the cavity surface of the movable type block 2 and the corresponding movable type block bottom surface 21 is greater than 15mm and less than 60mm, which allows for a reduction in the overall thickness of the movable type block. This reduces the thickness of the steel plate used to process the movable type block, thereby reducing the overall weight of the movable type block, facilitating manual handling, and improving safety during handling.

[0038] The bottom surface 21 of the movable type block is parallel to the back of the mold side plate 1. A transition surface 22 is provided between the bottom surfaces 21 of adjacent movable type blocks. The transition surface 22 is perpendicular to the back of the mold side plate 1. There is a gap between the transition surface 22 and the side wall of the mounting groove 11 to facilitate the installation of the movable type blocks.

[0039] like Figure 2 As shown, the movable type block 2 has three movable type block bottom surfaces 21. The innermost and outermost movable type block bottom surfaces 21 are in close contact with the bottom of the mounting groove 11, and there is a gap between the middle movable type block bottom surface 21 and the mounting groove 11. As long as the inner and outer movable type block bottom surfaces 21 are in contact with the bottom of the mounting groove 11, the movable type block can be installed in place. The contact area is small, which reduces the processing cost.

[0040] When the bottom surface 21 of the innermost and outermost movable type blocks is tightly attached to the bottom of the mounting groove 11, the cavity surface of the innermost and outermost movable type blocks 2 is provided with connecting countersunk holes 25. The mold side plate 1 is provided with connecting screw holes corresponding to the connecting countersunk holes 25. The screws 23 are installed in the connecting countersunk holes 25 and are threadedly connected to the connecting screw holes. The bottom surface 21 of the movable type blocks is tightly attached to the mounting groove 11, which provides support for the cavity surface of the movable type blocks 2. The movable type blocks will not be dented or deformed due to the force applied to the movable type blocks 2 by the tightening of the screws 23.

[0041] The cavity of the movable block 2 is provided with a cover plate 24 corresponding to the countersunk hole 25. The cover plate 24 seals the screw 23 inside the countersunk hole 25, so that the tire blank will not enter the countersunk hole 25, thus ensuring the appearance of the tire surface.

[0042] The mold side plate 1 is provided with a disassembly hole 12 that penetrates the back of the mold side plate 1 and the mounting groove 11 for the movable block 2, or the connecting countersunk hole 25 is machined with a disassembly thread, so that the movable block 2 can be pushed out of the mold side plate 1 with a tool, or the movable block 2 can be pulled out from the mounting groove 11 by screwing the disassembly screw into the disassembly thread.

[0043] Other embodiments of this disclosure provide a tire mold, such as Figure 2 As shown, the tire mold type blocks include any of the above embodiments.

[0044] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
