Lower chuck of vulcanizing machine

The utility model relates to the technical field of tire vulcanizing machines, in particular to a lower chuck of a vulcanizing machine. A lower chuck of a vulcanizing machine comprises: a lower chuck body, the upper end of which is provided with a circular groove; a circular through hole is formed in the middle of the cover plate, and the cover plate is arranged in the circular groove of the lower chuck body. The lower chuck has the advantages that the upper end of the lower chuck is divided into the lower chuck body and the cover plate, air with small thermal conductivity exists between the lower chuck body and the cover plate, generation of water vapor can be reduced, the cover plate is made of stainless steel materials with small thermal conductivity, original product characteristics are reserved, generation of the water vapor can be reduced, and the service life of the lower chuck is prolonged. And the operation efficiency of the vulcanizing machine is greatly improved. 本实用新型涉及轮胎硫化机技术领域，尤其涉及一种硫化机的下夹盘。一种硫化
