The present invention relates to a manufacturing method and a manufacturing apparatus of a one-piece shoe, and more particularly to a manufacturing method and a manufacturing apparatus of a one-piece shoe that can be formed integrally with the midsole and upper in one mold.

Korea's footwear industry has grown based on abundant labor force since the 1920s and has built a solid production base such that the total output reached 500 million pairs in the late 1980s.However, exports were pushed down by price competitiveness with developing countries such as China and Indonesia in the 1990s. The industry slumped sharply, from $ 4.3 billion to $ 600 million.

However, Korea is regarded as having a global competitiveness in parts and materials. At this time, EVA midsole (midsole or phylon) is widely used as a shoe midsole part because of its light and shock absorbing properties, and this midsole manufacturing is suitable for mass production, and the demand for a small amount of midsole is based on pyron press ( Work method by phylon press is much more competitive. In the shoe manufacturing industry, midsole manufacturing is a shoe parts field that can have superior competitiveness in Korea compared to other countries such as China, Indonesia and the Philippines.

On the other hand, the current midsole manufacturing method is facing a limitation of productivity. This is because there are many problems in the way of working, because of the limitations of the current pylon mold shape, which does not contribute to the improvement of productivity. In other words, after producing the pattern upper (upper) and pylon molds, the two products are bonded together in a separate process to make a finished product (sandals, etc.), thereby increasing the mold manufacturing cost for producing a mold for producing the two products separately. As the production process increases, it takes a lot of time to produce the product, which is a factor of major product damage of the bonded part, which has a huge influence on the increase in productivity.

Korean Patent Laid-Open Publication No. 1998-033746 "Shoe manufacturing method in which the upper and the rubber sole are integrated by using the molded foam and the non-foamed material in a mold" and a midsole with different physical properties and functions in a mold In the manufacturing method of forming and bonding the outsole, the foam-formed plate made of the EVA base compound is cut long and inserted into the mold, and the upper of which is covered with the upper bone with the foamed midsole material of the same material in the middle of the mold is a lid. When the inside of the mold becomes the open space, the temperature and pressure inside the mold are prevented from leaking to the outside, and when the pressure is released momentarily, the expanded midsole is expanded with the expansion force that the expandable midsole material expands and expands. The shaped strips are pressed again to the inside of the mold, and are molded. A shoe manufacturing method is proposed in which the upper and the outsole are integrally bonded to each other by inflating force.

Korean Patent Laid-Open Publication No. 2000-0017889 "Shoes and uppers of which soles are integrally bonded together and a method of manufacturing the same" is a plate-shaped uncured rubber sheet on the upper surface of the lower mold provided with an outsole forming portion and a color preventing member on the upper portion thereof. Positioning a; Position the intermediate mold with the midsole forming part over the lower mold, and place the round frame of foam-molded EVA material made of the midsole outline shape with a height slightly larger than the midsole forming part and having a thickness of about 5 to 10 mm. Making a step; Positioning a foam cushioning material having different physical properties from that of the circular frame inside the intermediate mold with a circular frame; Positioning the upper mold to the upper surface of the middle mold made of aluminum material and the foot-shaped new bone is attached to the bottom and the upper is coated on the outer surface of the new bone; Supplying gas to the cushioning material located in the circular frame through press and heating by a press and a separate gas supplier; It is composed of the step of discharging the gas generated by the crosslinking of the cushioning material to the outside by the supplied gas and the chemical reaction by heating to foam expansion of the cushioning material. It is proposed a shoe manufacturing method that is characterized in that the upper and the sole is integrally bonded.

The proposed techniques suggest an integrated shoe through foam molding. However, these technologies are actually difficult to manufacture a one-piece shoe through automation in the actual process. That is, the conventionally proposed techniques suggest a method of forming an integrated shoe by applying a manufacturing apparatus, that is, a mold, and allowing the upper and the midsole (or the outsole) to be bonded in the mold, but each component forming each part of the shoe The process of putting the mold into the mold and the process of separating the finished shoe from the mold has to be limited by the operator's intervention, except that the upper and the midsole are bonded without the use of an adhesive. Rather, it is more complicated than the general shoe manufacturing process, so it is difficult to reduce the actual cost.
