[Title] A method for manufacturing a foamable midsole using a mold and a high pressure inside a sealed box;[PROBLEMS] In order to make the inside of the mold to be a closed space, a compressed air injection side is formed on one side of the mold, a midsole pillar and an outsole are inserted into the mold, compressed air is injected into the mold and a high heat is applied to the mold through a hot press The method of integrating the midsole and the outsole is complicated in terms of the device condition that prevents the inflated air pressure from flowing out to the outside, and the manufacturing process of the mold is complicated.;In other words, there is a disadvantage that it is not possible to carry out a major modification of the currently used mold without applying the sealing technology directly to the mold.;[MEANS FOR SOLVING PROBLEMS] A separate aluminum box which can be heated is manufactured, and a variety of ordinary molds, which have been slightly modified without sealing technology, are inserted in the box to block air from the outside, The high temperature is applied at the same time as the injection, so that the air pressure inside the mold and the air pressure in the upper box are equal to each other, and then the compressed air is discharged from the aluminum box to mold the midsole material.
