무발포 소재가 부착된 신발 밑창의 제조방법{The manufacturing process of outsole attached none-forming material}The manufacturing process of outsole attached none-forming material}

본 발명은 무발포 소재가 부착된 신발 밑창의 제조방법에 관한 것으로, 더욱 상세하게는 폴리우레탄으로 발포 성형된 신발 밑창의 바닥면에 고무를 부착하는 작업을 한벌의 금형에서 이루어지게 하되, 무발포 성형물의 성형 지느러미를 제거하고 무발포 성형물이 무발포용 상형의 무발포용 성형돌기에 달라붙어 무발포 성형공에서 이탈하지 못하도록 무발포용 상형과 하형의 사이에 비닐을 삽입한 후에 고무나 인조고무 등을 무발포 성형하고, 비닐을 제거하며, 이후에 폴리우레탄으로 신발 밑창을 발포 성형함으로써, 비닐의 제거만으로 불필요한 무발포 성형물의 성형 지느러미가 제거되므로 작업성이 향상되고, 미끄럼 방지용 고무를 접착제로 부착하는 번거로움과 접착제에 의한 오염이 방지되어 상품의 외관이 미려하여 상품성이 증대되는 효과가 있는 무발포 소재가 부착된 신발 밑창의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a shoe sole attached to a non-foaming material, and more specifically, to attach a rubber to the bottom surface of a shoe sole foamed with a polyurethane to be made in a single mold, a non-foaming Remove the forming fins of the molding and insert the vinyl between the non-foaming upper mold and the lower mold so that the non-foaming mold adheres to the non-foaming molding protrusion of the non-foaming upper mold so as not to escape from the non-foaming molding hole. By foamlessly forming the back, removing the vinyl, and then foaming the sole of the shoe with polyurethane, unnecessary molding foam of the non-foamed molding is removed only by removing the vinyl, thereby improving workability and using an anti-slip rubber as an adhesive. Prevents the hassle of attaching and contamination by adhesives, so that the appearance of the product is beautiful and the productability is increased. Non-foaming material is attached to shoe soles, which relates to a method of manufacturing the same.

일반적으로 신발 밑창은 주로 폴리우레탄으로 발포 성형되고, 폴리우레탄의 단점인 미끄러짐을 방지하기 위하여 고무나 인조고무를 특정 형상으로 미리 성형하여 신발 밑창에 접착제로서 부착시켜 제조하거나, 한벌의 금형 장치에서 하형을 고정하고 무발포형 상형과 발포형 상형을 번갈아 교체하여 사용하고 있다.In general, shoe soles are mainly foam-molded with polyurethane, and in order to prevent slippage, which is a disadvantage of polyurethane, the rubber or artificial rubber is pre-molded into a specific shape and attached to the shoe sole as an adhesive, or a lower mold in a single mold device It is used to replace the non-foaming type and the foam type.

그러나, 이와같은 종래의 폴리우레탄의 발포 성형으로 된 신발 밑창의 미끄러짐을 방지하기 위하여 고무를 접착제로 부착하는 방법은 별도의 고무 성형 금형이 필요하여 제조비용이 증가되고, 접착제로 부착한 경우 접착 가장자리가 지저분하게 오염되며, 접착면이 떨어지는 문제점이 있다.However, in order to prevent slippage of shoe soles made of foam molding of the conventional polyurethane, a method of attaching rubber with an adhesive requires a separate rubber molding mold, which increases manufacturing cost, and when the adhesive is attached, an adhesive edge Is dirty, and there is a problem that the adhesive surface falls.

그리고, 폴리우레탄 발포 성형의 신발 밑창의 미끄러짐을 방지하기 위하여 고무를 무발포 성형하고 폴리우레탄을 발포 성형하기 위하여 한벌의 금형으로 구성된 경우는 상형을 바꾸어 가면서 작업을 하여야 하므로 작업이 번거로워 작업 능률이 저하되는 문제점이 있고, 무발포 성형을 위해 주입되는 액상의 고무의 양이 정확하지 않을 경우 무발포 성형공을 초과한 액상의 고무가 성형 지느러미를 형성시켜 월색이 되는 상품성 저하의 문제점이 있으며, 상기의 문제점을 해결하기 위하여 성형 지느러미를 일일이 손으로 제거하는 경우는 작업의 효율이 저하되는 문제점이 있고, 무발포 성형 후에는 고무 등의 미끄럼 방지용 무발포 성형물은 하형의 무발포 성형공에 남아 있어야 하는데도 불구하고 무발포 성형물이 무발포용 상형의 무발포용 성형돌기에 부착되어 무발포용 상형을 들어올리 때 같이 인출되어 작업자가 일일이 뜯어서 다시 제위치인 하형의 무발포 성형공에 끼워주는 불편한 문제점이 있다.And, in order to prevent slipping of the shoe sole of polyurethane foam molding, the rubber is non-foamed, and in the case of a single mold for foaming polyurethane, the work has to be done while changing the upper mold, thus reducing work efficiency. There is a problem that, if the amount of the rubber in the liquid injected for non-foaming molding is not accurate, there is a problem of deterioration of the merchandise deterioration that the rubber of the liquid exceeding the non-foaming forming the forming fins to become a brown color, In order to solve the problem, when removing the molded fins by hand, the efficiency of the work is deteriorated, and after the non-foaming molding, the anti-foaming moldings such as rubber should remain in the non-foaming molding hole even though And non-foaming molded product is a non-foaming non-foaming forming protrusion When attached to the upper mold for non-foaming is pulled out together, there is an uncomfortable problem that the worker tears off one by one to fit into the lower mold-free molding hole of the lower position.

본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여, 폴리우레탄으로 발포 성형된 신발 밑창의 바닥면에 고무를 부착하는 작업을 경첩 구조로 형성된 3단 금형에서 이루어지게 하되, 무발포 성형물의 성형 지느러미를 손쉽게 제거하고 무발포로 성형된 고무 등의 무발포 성형물이 무발포용 상형의 무발포용 성형돌기에 달라붙어 탈형되지 못하도록, 무발포용 상형과 하형의 사이에 비닐을 삽입한 후에고무나 인조고무 등을 무발포 성형하고, 비닐을 제거하며, 이후에 폴리우레탄으로 신발 밑창을 발포 성형함으로써, 작업성이 향상되고 신발 밑창의 상품성을 증대시킬 수 있는 무발포 소재가 부착된 신발 밑창의 제조방법을 제공함에 있다.The object of the present invention, in view of the conventional problems as described above, the operation of attaching the rubber to the bottom surface of the shoe sole foamed with polyurethane to be made in a three-stage mold formed of a hinge structure, but the molding of a foam-free molding After inserting the vinyl between the non-foaming upper and lower molds so that the fins can be easily removed and the non-foaming moldings such as rubber formed without foaming stick to the non-foaming forming protrusions of the non-foaming upper mold.

여기서 사용되는 한벌의 금형은 바닥면에 무발포 성형공(6)을 가진 발포 성형공(5)이 형성된 하형(1)의 일측변에 무발포용 상형(2)이 경첩(12)으로 절첩되어 하형(1)과 결합되게 설치되고, 상기 일측변에 연접된 타측변에 발포용 상형(3)이 경첩(12)으로 절첩되어 하형(1)과 결합되게 설치되어 형성된 3단 금형(100)이다.A single mold used here is a non-foaming upper mold (2) is folded in the hinge 12 on one side of the lower mold (1) formed with a foam molding hole (5) having a non-foaming molding hole 6 on the bottom surface It is installed to be combined with the lower mold (1), the upper mold (3) for foaming on the other side connected to the one side is folded into the hinge 12 is formed in three steps of the mold 100 is formed to be combined with the lower mold (1). .

상기와 같이 하형(1)의 인접된 변에 무발포용 상형(2)과 발포용 상형(3)을 경첩(12)으로 절첩되게 설치할 수도 있고, 마주보는 변에 무발포용 상형(2)과 발포용 상형(3)을 경첩(12)으로 절첩되게 설치하여 실시할 수도 있다.As described above, the non-foaming upper mold 2 and the foaming upper mold 3 may be installed to the adjacent sides of the lower mold 1 by the hinge 12, or the non-foaming upper mold 2 on the opposite side thereof. The upper mold 3 for foaming may be provided by being folded with the hinge 12.

도면중 미설명 부호 13은 무발포용 상형(2)에 형성된 무발포용 성형돌기이고, 14는 무발포용 성형돌기(13)의 표면에 형성되어 무발포 성형공(6)에 얕게 결합되는 절취 돌기이다.In the drawings, reference numeral 13 denotes a non-foaming forming protrusion formed on the non-foaming upper die 2, and 14 is a cutout formed on the surface of the non-foaming forming protrusion 13 to be shallowly coupled to the non-foaming forming hole 6. It is a projection.

이와같이 된 본 발명은 한벌의 금형에서 간편한 조작으로 무발포 성형과 발포 성형이 순차적으로 행할 수 있고, 손쉽게 성형 지느러미를 제거할 수 있으며, 무발포 성형물(9)이 무발포용 성형돌기(13)에 부착되지 않으므로써 작업성의 향상과 양질의 신발 밑창(4)을 성형할 수 있게 된다.The present invention as described above can be carried out in a single mold in a non-foaming molding and foam molding in a simple operation, and can easily remove the molding fin, the foam-free molding (9) to the non-foaming molding projection (13) By not attaching, it is possible to improve workability and to form a high quality shoe sole 4.

제 1공정은 액상의 고무(7)를 주입하는 공정으로서, 폴리우레탄으로 발포 성형된 신발 밑창(4)의 미끄러운 단점을 해소하기 위하여 액상의 고무(7)를 무발포로 성형하게 되는데, 이를 위해 액상의 고무(7)를 주입하는 공정이다. 따라서 본 발명은 하형(1)의 발포 성형공(5)의 바닥면에 무발포 성형공(6)을 형성시켜 액상의 고무(7)나 인조고무 등의 미끄럼 방지용 무발포 성형물(9)을 성형할 수 있도록 하였다.The first step is to inject the liquid rubber (7), in order to eliminate the slippery disadvantages of the shoe sole (4) foamed with polyurethane, the liquid rubber (7) is molded into a non-foaming, for this purpose It is the process of inject | pouring the rubber | gum 7 of a liquid. Accordingly, the present invention forms a non-foaming molding hole (6) in the bottom surface of the foam molding hole (5) of the lower mold (1) to form a non-slip molding (9) for non-slip, such as liquid rubber (7), artificial rubber I could do it.

제 2공정은 비닐(8)을 삽입하는 공정으로서, 이는 무발포 성형물(9)의 성형지느러미를 비닐(8)을 제거함으로써 제거되게 하고, 액상의 고무(7)가 무발포 성형물(9)로 성형된 후 무발포용 상형(2)을 들어 올릴 때 무발포 성형물(9)이 무발포용 성형돌기(13)에 달라붙어 탈형되는 것을 방지하기 위함이다. 여기서 비닐(8)은 무발포용 상형(2)과 하형(1)의 사이에 삽입하거나 무발포용 상형(2)에 씌울 수도 있다. 제 1공정에서 액상의 고무(7)는 무발포 성형공(6)에 알맞게 채워져야 하는데, 많은 양의 액상의 고무(7)가 채워지면 무발포용 상형(2)을 하형(1)에 결합시킬 때 무발포용 성형돌기(13)에 의해 여분의 액상의 고무(7)가 분출되어 성형 지느러미를 형성시키게 된다. 따라서 종래에는 이러한 문제점으로 월색이 발생하여 상품성이 저하되고, 이를 방지하기 위하여 일일이 작업자가 성형 지느러미를 제거하였다. 그러나 본 발명은 향후의 이러한 공정을 비닐(8)의 제거만으로 가능하게 된다.The second step is to insert the vinyl (8), which causes the forming fins of the non-foaming (9) to be removed by removing the vinyl (8), and the liquid rubber (7) into the non-foaming (9). This is to prevent the non-foaming molded product 9 from sticking to the non-foaming forming protrusion 13 and demolding when lifting the non-foaming upper die 2 after being molded. The vinyl 8 may be inserted between the non-foaming upper mold 2 and the lower mold 1 or may be covered with the non-foaming upper mold 2. In the first process, the liquid rubber (7) should be filled appropriately to the non-foaming molding hole (6). When a large amount of liquid rubber (7) is filled, the non-foaming upper mold (2) is bonded to the lower mold (1). When it is made, the excess liquid rubber 7 is ejected by the non-foaming forming projection 13 to form the forming fin. Therefore, conventionally, due to such a problem, the color of the product is lowered, and the commerciality is removed, in order to prevent this, the worker removes the molding fins. However, the present invention enables this future process only by removing the vinyl 8.

제 3공정은 액상의 고무(7)를 무발포 성형물(9)로 성형시키는 공정으로써, 무발포용 상형(2)을 경첩(12)을 중심으로 절첩시키면 무발포용 성형돌기(13)가 비닐 (8)을 누르게 되어 필요 이상의 액상의 고무(7)는 무발포 성형공(6)의 외부로 토출되고 무발포용 성형돌기(13)에 형성된 절취 돌기(14)가 무발포 성형공(6)에 결합되어 정확하고 깨끗한 형상의 무발포 성형물(9)을 성형시킬 수 있게 된다. 이 때 외부로 토출된 액상의 고무(7)는 성형 지느러미로 성형되어 이후 공정에서 제거되게 된다. 무발포 성형공(6)은 비닐(8)과 무발포용 성형돌기(13)의 절취 돌기(14)에 의해 무발포로 액상의 고무(7)를 성형할 때에 외곽이 깨끗하고 양호한 모양을 가지게 된다. 그리고, 무발포 성형공(6)과 절취 돌기(14)에 의해 다양한 색상의 무발포 성형물(9)로 성형하더라도 월색이 없게 되므로 깨끗한 외관을 가질 수 있고,비닐(8)과 절취 돌기(14)를 사용함으로써 무발포 성형물(9)이 무발포용 성형돌기 (13)에 달라붙지 않게 됨은 물론이고 액상의 고무(7)가 무발포 성형공(6)을 벗어나 성형 지느러미와 같은 지저분한 것이 없어져 월색의 단점이 없게 되는 것이다.The third step is a step of forming the liquid rubber 7 into the non-foaming molded product 9. When the non-foaming upper mold 2 is folded around the hinge 12, the non-foaming forming protrusion 13 is made of vinyl. (8) is pressed so that the liquid rubber 7 more than necessary is discharged to the outside of the non-foaming molding hole 6, and the cutting protrusions 14 formed on the non-foaming molding protrusion 13 have no foaming molding hole 6 It can be combined to be able to mold the foam-free molded article 9 of accurate and clean shape. At this time, the liquid rubber 7 discharged to the outside is molded into a forming fin and then removed in a subsequent process. The non-foaming molding hole 6 has a clean and good shape when forming the liquid rubber 7 without foaming by the cutting protrusions 14 of the vinyl 8 and the non-foaming forming protrusions 13. do. In addition, even when the non-foaming molded product 9 of various colors is formed by the non-foaming molding hole 6 and the cutting protrusion 14, there is no gray color, and thus a clean appearance can be obtained, and the vinyl 8 and the cutting protrusion 14 The non-foaming molded product 9 does not stick to the non-foaming forming projection 13 by using the liquid, and the liquid rubber 7 escapes the non-foaming forming hole 6, and there is no messy matter such as forming fins. There will be no disadvantages.

제 4공정은 비닐(8)을 제거하고 액상의 폴리우레탄(10)을 주입하는 공정으로서, 무발포 성형이 완료되어 무발포용 상형(2)을 경첩(12)을 중심으로 절첩시켜 올리면 무발포 성형물(9)은 무발포 성형공(6)에 남아 있게 되는데, 이는 비닐(8)을 사용함으로써 무발포 성형물(9)이 무발포용 상형(2)의 무발포용 성형돌기(13)에 달라붙는 것이 방지되기 때문이다. 무발포 성형이 끝난 후에는 무발포용 상형(2)과 하형 (1) 사이의 비닐(8)을 제거하고, 무발포용 상형(2)에 비닐(8)을 씌워 무발포 성형을 행한 경우는 무발포용 상형(2)을 들어주기만 하면 비닐(8)은 제거된다.The fourth step is a step of removing the vinyl (8) and injecting a liquid polyurethane (10), when the foam-free molding is completed and folded up the non-foaming upper mold (2) around the hinge 12, the foam-free The molding 9 remains in the non-foaming molding hole 6, in which the non-foaming molding 9 is different from the non-foaming forming projection 13 of the non-foaming upper mold 2 by using the vinyl 8. This is because sticking is prevented. After the non-foaming molding is finished, the vinyl (8) between the non-foaming upper mold (2) and the lower mold (1) is removed, and the non-foaming foam (2) is covered with vinyl (8) to perform non-foaming molding. The vinyl 8 is removed only by lifting the non-foaming upper die 2.

여기서, 비닐(8)에는 여분의 액상의 고무(7)가 성형된 성형 지느러미가 부착되어 있는데, 본 발명은 비닐(8)의 제거만으로 불필요한 성형 지느러미를 제거할 수 있는데 그 특징이 있다. 따라서 종래의 작업자가 일일이 성형 지느러미를 제거하는 작업을 배제할 수 있어 작업의 능률이 향상되고, 월색이 없어 상품성이 증대되는 것이다.In this case, the vinyl 8 is attached with a molded fin in which an extra liquid rubber 7 is formed. The present invention is characterized by removing unnecessary molded fins only by removing the vinyl 8. Therefore, the conventional operator can eliminate the work to remove the molding fins one by one to improve the efficiency of the work, there is no color to increase the merchandise.

비닐(8)을 제거한 후에 하형(1)의 발포 성형공(5)에 액상의 폴리우레탄(10)을 주입하게 된다.After the vinyl 8 is removed, the liquid polyurethane 10 is injected into the foam molding hole 5 of the lower mold 1.
