Document Type and Number:
WIPO Patent Application WO/2023/193397
Kind Code:
A1
Abstract:
Disclosed in the present invention are a shoe manufacturing mold and manufacturing method. The manufacturing mold comprises an upper mold, a middle mold, a lower mold and a shoe tree which can be in seal fit, an upper cavity being arranged on the upper mold, a middle cavity being arranged on the middle mold, lower cavities being arranged on the lower mold, the lower cavities and the middle cavity constituting a shoe midsole forming cavity, the upper end of the shoe tree being installed in the upper cavity, the lower end of the shoe tree being inserted into the shoe midsole forming cavity, the shoe tree being provided with a first heating and cooling channel passing through the upper end surface of the shoe tree and a plurality of air channels distributed on the bottom surface of the shoe tree and respectively communicating with the first heating and cooling channel, and the upper mold being provided with a second heating and cooling channel passing through the upper end and the lower end of the upper mold and leading to the shoe midsole forming cavity. In the present invention, there is no need to heat or cool the mold during a shoemaking process, realizing a simple process and high production efficiency. By means of carbon dioxide, the present invention may make the whole shoemaking process friendlier to environment, and, during the shoemaking process, makes a shoe midsole capable of better bonding with a shoe outsole and a vamp during foaming, realizing better shoe quality.
