[0002] In the production process of EVA shoe sole, the traditional shoe sole shaping device often adopts relatively simple demolding mode, for example, simply ejection demolding or direct manual demolding etc. These methods have many disadvantages, on the one hand, the shoe sole is tightly adsorbed on the surface of the mold after forming due to the suction force, friction force between the shoe sole and the mold and the viscosity of the material itself and other factors, so that a lot of manpower and time are needed when demolding, which seriously affects the production efficiency. On the other hand, forced demolding may also cause deformation and damage of the shoe sole, and even cause a certain degree of wear of the mold, increasing the production cost and the frequency of mold maintenance. Moreover, with the increasing demand for EVA shoe sole in the market, the low efficiency and high damage of the traditional demolding mode have become the key bottleneck restricting the expansion of production scale and the improvement of product quality. Therefore, there is an urgent need for a technical solution that can efficiently and conveniently realize the demolding of shoe sole to meet the requirements of modern industrialized production for rapid and high-quality production of EVA shoe sole, and the design of the rotating demolding assembly and related structures in the present technical solution is to solve the actual production problems in this background.
