Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tire mold technology, specifically relating to a tire mold tread block assembly device. Background Technology
[0002] Most tire molds consist of a mold shell and tread blocks. Tread blocks are mold components used for shaping and vulcanizing the tire tread pattern. The number of tread blocks that make up different specifications of molds varies. Tread blocks are made from whole blanks through processing, division or individual casting, and then fixed on the mold shell along the inner ring of the mold shell using fasteners or other methods.
[0003] To improve the performance of tire molds, the structural design of each component in the tire mold is constantly being innovated. To make the structure more compact and reduce cumulative errors, the tread blocks and sliders are designed as an integrated structure. To improve tire ground contact and noise performance, more tread blocks are changed from straight seams to S-shaped seams.
[0004] Currently, CN105171986B provides a combined device for inspecting items such as the gap between the inner hole and the back side of the patterned block during precision machining, the gap between the vertical seams, the pattern joint at the vertical seams, and trial assembly. When the dividing seam is an S-shaped parting surface, due to the mutual interference of the S-shaped parting surfaces, it is impossible to install the block into such a mold shell from top to bottom, making it impossible to perform dimensional accuracy measurement, coaxiality inspection of the inner hole and outer circle, and roundness inspection.

[0045] Example 1
[0046] Please refer to Figures 1-10 This embodiment provides a tire mold tread block assembly device. The tread block 3 is an S-shaped slit tread block. The vertical slit of this tread block is not a vertical plane, but a curved surface, such as... Figure 10As shown, during assembly, it is impossible to arrange all the tread blocks sequentially from top to bottom on the same plane and form a complete circle. The tire mold tread block assembly device provided in Embodiment 1 includes a mold shell 1 and a conversion body 2 for fixing the tread blocks 3. The mold shell 1 includes an outer shell 1.1 and a base 1.2. The outer shell 1.1 of the mold shell 1 surrounds the outside of the conversion body 2, and the base 1.2 of the mold shell 1 supports the lower end of the conversion body 2. The inner surface of the conversion body 2 is adapted to the outer surface of the tread blocks 3, and the tread blocks 3 are detachably installed on the inner surface of the conversion body 2. The mold shell 1 has a radially open first slot 1.3, and the conversion body 2 has a radially open second slot 2.1. The first slot 1.3 and the second slot 2.1 are circumferentially corresponding. It also includes a stop block 4, which is blocked at the first slot 1.3 and the second slot 2.1 and fixedly connected to the mold shell 1. After the stop block 4 is fixedly connected to the mold shell 1, a ring-shaped device is formed. When pressure is applied to the tread blocks 3, the ring-shaped device can bear pressure and measure items such as gaps. The slot design allows patterned block 3 to be quickly inserted into the converter from top to bottom. The last patterned block 3 is pushed in from the outside to the inside from the slot position, and the S-shaped slit matches the slit of the already inserted patterned block 3.
[0047] The converter 2 and the patterned block 3 are connected together by connecting screws. The patterned block 3 has threaded holes, the mold shell 1 has through holes, and the converter 2 has countersunk holes. Both the countersunk holes and the through holes are correspondingly designed elongated holes. The design of the elongated holes can improve the versatility of the converter 2 and adapt to a certain range of patterned blocks 3.
[0048] The lower ends of the mold shell 1 and the patterned block 3 are connected together by connecting screws. The patterned block 3 is provided with threaded holes, and the base 1.2 of the mold shell 1 is provided with countersunk holes.
[0049] The inner surface of the stop block 4 is adapted to the outer surface of at least one patterned block 3, and at least one patterned block 3 can be detachably installed on the inner surface of the stop block 4; the stop block 4 and the patterned block 3 are connected together by connecting screws, the patterned block 3 is provided with threaded holes, the stop block 4 is provided with countersunk holes, the countersunk holes are elongated holes, and the elongated holes on the stop block 4 can be consistent with the specifications of the elongated holes on the converter.
[0050] Both the first slot 1.3 and the second slot 2.1 are U-shaped openings facing upwards. The upper end of the patterned block 3 is higher than the upper ends of the mold shell 1 and the conversion body 2. The U-shaped openings facilitate the patterned block to be pushed in from the outside to the inside. The bottom surfaces of the first slot 1.3 and the second slot 2.1 are flush. The side walls of the first slot 1.3 and the second slot 2.1 in the same direction are located on the same plane. The side walls on the left and right sides converge towards the axis of the patterned block 3. The conversion body 2 is also provided with a limiting surface 2.2. The stop block 4 slides smoothly into the bottom surface of the slot from the outside to the inside. When the inner side of the stop block 4 fits against the limiting surface 2.2, it is assembled in place.
[0051] Positioning platforms 4.1 are provided on the left and right sides of the stop block 4, and corresponding connecting grooves are provided on the outer circle of the mold shell 1. The positioning platforms 4.1 are pressed into the connecting grooves, and the stop block 4 and the conversion body 2 are fixedly connected together.
[0052] The mating surface between the positioning platform 4.1 and the connecting groove is a plane, or, as... Figure 9 As shown, the mating surface between the positioning platform 4.1 and the connecting groove is an arc surface. When the mating surface is an arc surface, circumferential adjustment can be made to facilitate the mating of the last patterned block with the seam of the patterned block that has been placed from above.
