[0002] A vulcanizer is a device used for vulcanization of rubber products. It cross-links rubber molecular chains through heating and pressure, thereby improving the physical properties and chemical stability of the rubber. Vulcanizers are widely used in the rubber products industry, such as tires, seals, pipes and other fields.

[0003] After searching, the announcement number is CN211662461U, and the name is a vulcanizing machine, including a frame. Through research and analysis, it is found that although it has the advantage of uniform heating of the mold table, it still has the following disadvantages to a certain extent.

Therefore, when a different mold is needed, it is not convenient to remove the original mold for replacement, which reduces the convenience of mold replacement. In addition, the surface of the object is hot after processing, and it does not have the function of cooling the object. Therefore, when the staff takes it, they are easily scalded, which reduces the safety during use. In order to solve the above technical problems, we have designed a vulcanizing machine that is easy to replace the mold. Utility Model Content
