The existing process rubber crawler vulcanization molding machine mostly uses two machines to form a whole crawler in two stages, or one machine uses a rotating device to form a whole crawler in two stages.

[0003] The disadvantages of this process are: the hot plate heating device needs to be disconnected when taking the product, the positioning and tensioning of the steel belt are manual operations, the labor intensity of workers is high, the efficiency is low, the heat loss of the hot plate and mold is large, the process is cumbersome, and more equipment and molding times are invested.
