Patent ID: 11465378

Abstract:
A method for preparing a shoe shell using a twice-opening-mold shoe-making mold comprises steps of preparing rubber for the shoe shell and cutting the rubber for the shoe shell into elongated or square sizes; heating the twice-opening-mold shoe-making mold to required temperatures within 3 hour; and opening the twice-opening-mold shoe-making mold with the bottom mold of the twice-opening-mold shoe-making mold being opened in a direction away from the mold main body of the twice-opening-mold shoe-making mold; putting the rubber for the shoe shell into the twice-opening-mold shoe-making mold; closing the bottom mold towards the mold main body, lifting the mold inner edge of the twice-opening-mold shoe-making mold to be stored into the mold main body until the bottom mold and the mold main body are closed, and performing a heating for 2-8 minutes; separating the bottom mold from the mold main body periodically during heating; reopening the twice-opening-mold shoe-making mold; taking out a semi-finished shoe shell; and trimming the semi-finished shoe shell.
