MANUFACTURING PROCESS OF SHOE SOLE

摘要

PURPOSE:To increase largely productivity and reduce remarkably cost by positioning an unvulcanized rubber containing material sheet 1a with a rapid vulcanizing speed on a design mold side and unvulcanized rubber sheet containing material on a lid mold side to load them and by molding a shoe sole having a riser at the toe tip and at the heel with the external periphery in a vulcanized state and the internal periphery in a vulcanized state. CONSTITUTION:An unvulcanized rubber containing sheet 1a with a rapid vulcanizing speed and an unvulcanized rubber containing material 1 of unvulcanized rubber containing sheet 1b with a slow vulcanizing speed is fit into a slit for a design mold 2 of molding shoe sole of a mold M for molding shoe sole comprising a lid mold 3 having a surface attached with shoe sole design 21, and a riser at the toe tip 22 and a riser at the heel 23. At this time both the design mold 2 and the lid mold 3 are adjusted to 130-180 deg.C. Or only the design mold is selected and the lid mold 3 is adjusted to 60-90 deg.C. Then after loading a sheet- like unvulcanized rubber containing material 1 into a slit for molding shoe sole the mold M for molding shoe sole is pressed and fit to mold shoe sole 12.
