The types of slippers are differentiated according to wearing occasions and performance purposes.

The slipper can be formed by separating the sole die from the vamp die, and then the cast sole and vamp are connected and combined, so that the mode not only needs to increase labor intensity and production steps in multiple steps, but also is not firm enough in connection between the bonded vamp and sole, and is easy to break off. For this reason, chinese patent CN210617364U (publication No. 2020.05.26) discloses a slipper mold with integrally formed upper and sole, which realizes the integral production of upper and sole. Chinese patent CN1623464 (publication No. 2005.06.08) also discloses a method for producing a foamed sole, in which an upper mold cavity and a bevel mold cavity are formed by combining upper and lower mold halves and a middle mold, so as to form a space shape with a vamp.

However, both of the above patents describe the manufacture of integrated slippers in the theoretical layer, and do not give specific mold structures. In the mold manufacturing and debugging process, after the upper mold and the lower mold are separated, the shoe last mold is sometimes not separated from the upper mold due to the adhesion force between the upper surface of the upper mold and the upper mold, and the production efficiency is influenced due to the fact that the worker is required to manually assist in separation.
