The heating strip on the heating mechanism enters into the heating strip hole, and the heating plate enters into the heating plate groove, so that the lower mold base can be heated at the same time. The midsole of the shoe can foam quickly after being heated. Therefore, the heating mechanism can greatly improve the heating efficiency of the lower mold base, thereby improving the foaming efficiency of the midsole of the shoe.

[0032] 3. The first fixed ring and the second fixed ring are both fixedly arranged at the output end of the driving motor. Therefore, when the driving motor rotates, the driving wheel of the lower mold base and the driving wheel of the upper mold base can be driven to rotate synchronously, and the process of placing the sole blank, closing the mold for foaming, cooling and shaping, and demolding and taking out the parts can be realized at the same time, which greatly improves the processing efficiency.
