Title:
SHOE MIDSOLE MOLD
Document Type and Number:
WIPO Patent Application WO/2018/236187
Kind Code:
A1
Abstract:
The present invention relates to a shoe midsole mold comprising: an upper mold having a molding protrusion portion and multiple air discharge holes; and a lower mold having a molding groove and multiple air discharge holes, wherein the molding protrusion portion and the molding groove symmetrically match with each other. The shoe midsole mold is characterized in that molding protrusion portions of the upper mold or molding grooves of the lower mold are formed asymmetrically in one direction, and air discharge holes are formed on big toe parts of the molding protrusion portions (13) and of the molding grooves (23), respectively, as widely as the distance between the big toes. According to the shoe midsole mold according to the present invention, concentration of air discharge holes in the big toe parts of the molds can be prevented, thereby improving durability, and the arrangement interval between the molding grooves can be reduced. Accordingly, compared with conventional molds, three or four molding grooves can be arranged on a single surface such that mold specifications can be set very close to specifications of heating plates, thereby reducing energy consumption, improving productivity, and also reducing manufacturing costs.
