Method for manufacturing a one-piece shoe shell

Abstract

A method for manufacturing a one-piece shoe shell provides a method to produce a one-piece shoe shell having steps of: mounting a mold assembly on an injection molding machine; closing the mold assembly and forming a cavity that can produce a shoe shell having a sole, two lateral vamps and a quarter combined together; opening the mold assembly and ejecting the shoe shell. Because the sole, lateral vamps and quarter are integrally formed, a durability of the shoe shell is increased and the shoe shell is easily fabricated.

1 . A method for manufacturing a one-piece shoe shell comprising steps of:
 mounting a mold assembly on an injection molding machine, the mold assembly having a combinative outer mold and an inner mold, the outer mold and the inner mold controllable by the injection molding machine to combine with each other;   closing the mold assembly and having a cavity formed in the mold assembly, the cavity providing a space to form a shoe shell having a sole, two lateral vamps and a quarter combined together;   forcing molten plastic material into the mold cavity and forming the one-piece shoe shell having the sole, lateral vamps and quarter; and   opening the mold assembly and ejecting the shoe shell when the plastic material has cured sufficiently.   
     
     
         2 . The method for manufacturing a one-piece shoe shell as claimed in  claim 1  further comprising a step of mounting a fiber cover around the inner mold before closing the mold assembly to combine the fiber cover with molten plastic material to produce a shoe shell with fiber cover. 
     
     
         3 . The method for manufacturing a one-piece shoe shell as claimed in  claim 1  further comprising a step of mounting a block at a predetermined position on the inner mold before closing the mold assembly to make the shoe shell having a mounting space for mounting a protective sponge in the mounting space. 
     
     
         4 . The method for manufacturing a one-piece shoe shell as claimed in  claim 2  further comprising a step of mounting a block at a predetermined position on the inner mold before closing the mold assembly to make the shoe shell having a mounting space for mounting a protective sponge in the mounting space. 
     
     
         5 . The method for manufacturing a one-piece shoe shell as claimed in  claim 4 , wherein molten plastic material is thermoplastic plastic. 
     
     
         6 . The method for manufacturing a one-piece shoe shell as claimed in  claim 4 , wherein molten plastic material is thermosetting plastic.
