Description
본 발명은 파이론이나 EVA 스폰지로서 샌들 등의 신발창을 성형하는 제조방법에 관한 것이다.The present invention relates to a manufacturing method for molding soles such as sandals as pylon or EVA sponge.
종래에는 샌들 등의 신발창을 제조함에 있어서는 주로 PVC나 폴리에틸렌 등의 열가소성 합성수지로서 성형하거나 스폰지로서 발포성형하여 제조하므로 작업공정이 매우 복잡하여 작업성이 불량하고 대량생산이 용이하지 않으며 단가가 비싼 등의 폐단이 있었다.Conventionally, in manufacturing shoe soles such as sandals, it is mainly manufactured by molding a thermoplastic synthetic resin such as PVC or polyethylene, or by foam molding as a sponge, so that the work process is very complicated, so that the workability is poor, mass production is not easy, and the unit cost is high. There was a dissolution.
본 발명은 이와같은 점을 감안하여 안출한 것으로 1차 발포된 파이론이나 EVA 스폰지를 일정크기로 재단하여 2차 발포하고 이를 냉각과 동시에 신발창으로 성형하므로서 매우 간단한 작업공정에 의거 신발창을 제조한 것인데 이를 첨부도면에 의거 제조공정을 상술하면 다음과 같다.The present invention has been made in view of such a point that the first foamed pylon or EVA sponge is cut to a certain size and then foamed secondly and molded into a shoe sole at the same time as cooling to manufacture a shoe sole based on a very simple work process Referring to the manufacturing process according to the accompanying drawings as follows.

적정크기로 발포성형한 EVA 스폰지(1)에서 제조할 신발창의 두께에 맞는 크기의 스폰지판(1')을 재단한다.A sponge plate 1 'of a size suitable for the thickness of the shoe sole to be manufactured is manufactured by foaming the EVA sponge 1 to an appropriate size.
제 1 공정에서 재단한 스폰지판(1')을 가열프레스(2)에 넣어 약 200∼250℃ 이상의 고온에서 약 3∼5분 동안 가열 압축하여 2차 발포시킨다.The sponge plate 1 'cut out in the first step is put into a heating press 2 and heated and compressed for about 3 to 5 minutes at a high temperature of about 200 to 250 DEG C or higher to secondary foam.
이때 2차 발포되면 제 1 공정의 스폰지판(1')보다 약 20∼30% 크기가 커진 2차 발포스폰지판(3)가 얻어진다.At this time, the secondary foamed sponge plate 3 having a size of about 20 to 30% larger than the sponge plate 1 'of the first step is obtained when the secondary foaming is performed.
여기서, 스폰지판(1')이 매우 두꺼울 경우 예를 들어 약 35∼40m/m 정도의 두께는 약 100℃에서 1차 예열하여 2차 발포시킨다.Here, when the sponge plate 1 ′ is very thick, for example, a thickness of about 35 to 40 m / m is first preheated at about 100 ° C. to second foam.
2차 발포스폰지판(3)을 냉각프레스(4)의 신발창 금형(5)위에 놓고 2차 발포스폰지판(3)의 상면에 요철홈(6)을 형성하는 그물망(7)을 깐 상태에서 냉각하면서 금형(5)의 형태대로 압축하여 2차 발포스폰지판(3)에 신발창 금형(5)의 형태로 각인 성형한다.The secondary foamed sponge plate 3 is placed on the sole mold 5 of the cooling press 4 and cooled in a state in which a mesh 7 for forming the uneven groove 6 is formed on the upper surface of the secondary foamed sponge plate 3. While compression in the form of the mold (5) is stamped in the form of the shoe mold (5) to the secondary foam sponge (3).
제 3 공정이 끝난 2차 발포스폰지판(3)을 냉각프레스(4)에서 탈형하여 트리밍기계로서 신발창을 절단해내면 신발창(8)이 제조된다.The shoe sole 8 is manufactured by demolding the secondary foamed sponge plate 3 after the third process by the cooling press 4 and cutting the shoe sole with a trimming machine.
이와같이 된 본 발명은 1차 발포시켜 성형한 EVA 스폰지(1)에서 신발창의 크기에 맞는 두께로 스폰지판(1')을 절단해내어 이를 가열프레스(2)에서 고온으로 원판보다 약 20∼30% 확대되도록 2차 발포시키고 이를 냉각프레스(4)에 장착한 신발창 금형(5)위에 놓고 그 상면에 요철홈(6)을 형성하는 그물망(7)을 깐 다음 냉각시키면서 가압 성형하게 되면 2차에 걸쳐 발포된 EVA 스폰지가 강한 밀도로 압축되면서 신발창(8)의 형태로 성형되므로 이를 트리밍기계에서 재단해내면 간단한 작업공정에 의거 신발창(8)을 제조할 수 있게 되는 것이다.According to the present invention, the sponge plate 1 'is cut to a thickness suitable for the size of the shoe sole in the EVA sponge 1 formed by primary foaming, and it is about 20 to 30% higher than the original plate at a high temperature in the heating press 2. Secondary foaming is carried out to expand and placed on the sole mold (5) mounted on the cooling press (4) and the mesh (7) forming the grooves (6) on the upper surface is laid and then press-molded while cooling, Since the foamed EVA sponge is molded in the form of the sole 8 while being compressed to a high density, it is possible to manufacture the sole 8 based on a simple work process by cutting it out in a trimming machine.
그리고, 2차 발포스폰지판(3)을 냉각 성형시 뒷면에 그물망(7)을 놓고 가압성형하게 되므로 성형후 뒷면에 요철홈(5)이 각인되어 신발제조시 별도의 버핑공정을 필요로 하지 않게 된다.In addition, since the secondary foamed sponge plate 3 is press-molded by placing the net 7 on the back side during cold molding, the uneven groove 5 is stamped on the back side after molding so that no separate buffing process is required when manufacturing shoes. do.
이와같은 간단한 작업공정으로 성형된 신발창(8)은 파이론이나 EVA 스폰지로서 쿳숀이 매우 좋아 완충효과가 크고 작업성이 우수하여 경쟁력이 있을 뿐 아니라, 대량생산이 가능하여 단가가 저렴하며 재료의 로스나 폐기물은 분쇄하여 재활용할 수 있는 등 그 효과가 매우 크다.Sole (8) molded by such a simple working process is a pylon or EVA sponge, which is very cushioned and has a good cushioning effect and excellent workability, so it is not only competitive, but also mass production is possible, and the unit price is low. The waste is very effective because it can be crushed and recycled.
