With the development of society, people have higher and higher requirements on the beauty and diversity of shoes. One of the shoes with hollowed-out patterns on the side is popular, and the shoe has a color different from that of the sole body and is made of different raw materials. However, for the sole composed of a plurality of components made of different colors or even different raw materials, the components such as the hollowed-out side edges and the like are often required to be prepared separately in the preparation process, and then the components are placed in a mold for preparing the sole body to be prepared in an injection molding mode. On one hand, because the components are combined and bonded to form the final sole, the size control is particularly strict during the preparation of different components, and because the soles are generally made of plastic materials, the size is not easy to control, the stability is required to be improved, and the defective rate is high when different molds are adopted for preparation. On the other hand, in the process of injection molding the sole body, components such as the hollowed-out side edges are prepared and placed in a mold of the sole body, so that the raw materials of the sole body cannot be subjected to melt injection molding at too high temperature, otherwise the size of the formed hollowed-out side edges is affected, the raw materials of the sole body are required to be fully filled in the mold at lower temperature, and the applicant finds that in the process, the raw materials of the sole body are often insufficiently filled, and the product yield is greatly affected.
