BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shoe manufacturing apparatus, and more particularly, to a shoe manufacturing apparatus capable of efficiently and continuously performing a series of work processes, thereby improving production efficiency.

The shoe generally consists of an upper that surrounds the wearer's foot and foot and a sole that contacts the wearer's soles. The sole is also insole, midsole, and outsole. .

Among them, EVA midsole (midsole or phylon) is light and has excellent impact absorbability, and is widely used as a midsole component of a shoe.

Such midsole manufacturing is suitable for mass production, and in order to meet the demand for midsole of a small-sized small-sized item, it is proper to apply a working method using a phylon press.

In the shoe manufacturing industry, shoe parts industry that can have competitiveness in countries with leading technologies compared to emerging industrial countries is about the manufacturing apparatus of the midsole and the manufacturing method thereof.

On the other hand, current manufacturing methods of the midsole are confronted with productivity limitations.

This is due to the following limitations of the working method to such an extent that productivity can no longer be improved due to the structural limitations of the current shape of the phylon mold.

In other words, the work method by the pylon press produces the pattern upper and the pylon mold respectively, and then the two products are bonded in a separate process to make the finished product (sandals, etc.) There is a problem in that the cost of manufacturing the mold for the molding is increased.

Therefore, it takes a lot of time to produce the product because of the increase of the production process, and the bonded part becomes a big factor of the defective product such as deformed or peeled off due to many variables such as the operator's mistake and weather condition.

Therefore, it is urgent to develop an apparatus and a method for efficiently performing a series of work processes and improving the production efficiency in consideration of this point.
