Vulcanizing device for small-diameter synchronous belt

The vulcanizing device for the small-diameter synchronous belt comprises an inner mold and an outer mold, the outer mold is arranged into two symmetrically-arranged outer mold units in a split mode, the outer mold units are provided with forming grooves used for containing the inner mold and a belt blank, and the two ends of the inner mold are provided with a first connecting piece and a second connecting piece correspondingly; every two adjacent inner molds are detachably and fixedly connected through a first connecting piece and a second connecting piece. During installation, the two outer mold units can be separated, then the inner molds wound with the belt blanks are placed in the forming groove of one outer mold unit one by one, then the other outer mold unit is covered, the two outer mold units are closed, and then the following process is carried out. Through the method, the strip blanks can be processed in batches, and the working efficiency is improved. 本申请涉及一种用于小直径同步带的硫化装置，包括内模和外模，所述外模分体设置成两个对称设置的外模
