Description

Technical Field

[0001] The utility model belongs to the technical field of tire processing, and particularly relates to an electric heating vulcanization structure for bias tires. Background Art

[0002] In the tire manufacturing process, heating and vulcanization are usually carried out through a vulcanizer to cross-link the chain molecules in the rubber into a network structure, thereby changing the physical properties of the rubber and giving it excellent elasticity and wear resistance.

[0003] At present, traditional vulcanizers generally adopt steam heating. The steam temperature of this heating method is difficult to control stably, and there is a temperature difference at the inlet and outlet, which can easily cause uneven vulcanization of the tire. Steam heating requires very high sealing of the hot plate. If the sealing is not good, once the hot plate leaks, the high-temperature and high-pressure steam will form condensed water when it cools, affecting the uniformity of the mold temperature, resulting in local under-vulcanization of the tire during the vulcanization process, generating scrap and thus wasting materials.

[0028] In this embodiment, the vulcanization treatment of bias tires (also called bias rubber tires) is an important link in the tire manufacturing process, which plays a vital role in improving the physical properties, wear resistance, service life and surface quality of the tire. When the bias tire is vulcanized, it is first placed on the mold body 6, and then a group of mold bodies 6 are buckled, and the electric heating rod 4 on the heating plate 3 is started, so that the electric heating rod 4 heats the heating plate 3 and the mold body 6, and the vulcanizing agent is injected during the heating process. Through heating and injection of the vulcanizing agent, the internal molecules of the tire undergo a cross-linking reaction, thereby improving the physical properties of the tire. The electric heating rod 4 and the inner side wall of the straight hole 5 are tightly attached to each other without a gap, so that the heat conduction performance is better, the heating plate 3 can be evenly heated, and the tire is vulcanized evenly. At the same time, it is convenient to control the heat of the heating plate 3, and the mold body 6 is heated by the heating plate 3 to balance its temperature and maintain the temperature balance, thereby facilitating the subsequent vulcanization treatment of the tire.

[0030] In this embodiment, by setting the annular heat conductor 7, the heat dissipated from the electric heating rod 4 can be effectively heated to the radial fan surface of the mold body 6, thereby ensuring the temperature balance of the mold body 6. By setting the heat insulation plate 8, the heat dissipated from the heating plate 3 can be effectively insulated, thereby effectively protecting the vulcanizer body 1.

[0032] In this embodiment, when replacing the heating plate 3, first remove the fixing bolts 11, then operate the positioning mechanism to make the clamping rod 12 of the positioning mechanism away from the fixing plate 10, and then remove the heating plate 3. The loading and unloading is relatively quick, and the heating plate 3 is installed by the fixing bolts 11. The installation is relatively quick and the installation stability is high.

[0034] In this embodiment, when replacing the heating plate 3, first remove the fixing bolt 11, then connect the external pull rod with the card slot of the clamping rod 12, then pull the pull rod to make the pull rod drive the clamping rod 12 to move synchronously, so that the clamping rod 12 slides along the installation groove, and the clamping rod 12 slides away from the bottom of the heating plate 3, and then the heating plate 3 falls downward by its own gravity, so that the heating plate 3 can be quickly disassembled, and the heating plate 3 can be positioned by the clamping rod 12, so as to facilitate the subsequent installation of the fixing bolt 11 on the fixing plate 10, which is beneficial to the subsequent assembly of the heating plate 3.

[0035] In a further preferred embodiment of the utility model, a connecting block 14 is fixedly installed on one side of the mold body 6, and a rectangular tube 15 is arranged below the mounting plate 2. The rectangular tube 15 is slidably connected to the connecting block 14, and a positioning rod 16 is slidably provided on the rectangular tube 15. The positioning rod 16 slides through the connecting block 14 and the rectangular tube 15.

[0036] In this embodiment, when the mold body 6 needs to be replaced, the positioning rod 16 is first removed from the rectangular tube 15, and then the rectangular tube 15 is slid to make the rectangular tube 15 slide away from the connecting block 14. After that, the mold body 6 can be moved down from the vulcanizer body 1 for replacement, and the connecting block 14 is fixed by the positioning rod 16, so that the mold body 6 can be quickly assembled, and the assembly efficiency is high.

When the positioning rod 16 is inserted and the connecting groove is exposed, the reset spring is released and the positioning block 20 is ejected, thereby limiting the positioning rod 16. The positioning block 20 limits the positioning rod 16 to ensure that the positioning rod 16 will not separate from the rectangular tube 15, and the limiting effect is better.
