본 발명은 각종 운동화류의 신발에 사용되는 돌륜부를 갖는 신발중창의 신규한 성형방법을 제공코져함에 목적이 있다.An object of the present invention is to provide a novel molding method of a shoe sole having a wheel wheel part used for shoes of various sneakers.

일반적으로 신발중창은 발포성 스펀지체를 소재로하여 상부에는 신발갑피를 접착시키고 하부에는 신발 밑창을 접착하여 제품을 완성시키게 되는바, 근래에는 신발의 상품가치를 보다 향상시키기 위하여 중창의 성형소재가 되는 스펀지판을 주면에 날개판이 약간 연설되도록 예비가공처리하여 이를 가열프레스에 의한 후가공 처리인 포스트몰딩(post Molding)공정을 거치게 하므로서 신발중창의 주벽면에 돌륜벽을 형성시켜 신발갑피와 중창의 접합 강도를 일층더 강화시키고 신발의 외관미를 보다 향상시키게 된다.In general, the shoe midsole is made of a foamed sponge material, and the upper part of the shoe is adhered to the upper part of the shoe and the lower part of the shoe is attached to complete the product. In recent years, the molding material of the midsole is used to further improve the product value of the shoe. The sponge plate is pre-processed so that the wing plate is slightly spread on the main surface, and it is subjected to a post molding process, which is a post-processing process by a heating press, to form a stone wheel wall on the main wall of the shoe midsole, thereby bonding strength between the shoe upper and the midsole. To further enhance the appearance of the shoe.

이를 더욱 구체적으로 설명하면, 제1도와 같이 중창(1)을 성형시킴에 있어서, 중창의 주면에 바닥면(2)보다 높은 돌륜부(3)를 융설시켜 윤곽태를 이루도록 함에 있어서, 종래에는 제2도와 같이 소재가 되는 스펀지판(2a)의 주면에 날개편 (3a)을 연마 및 커팅공정으로 연설시키거나 별도의 윤곽태를 일일이 가접착(假接着)시켜서 소재화한 후 이를 후가공 포스트몰딩으로 제품이 완성되게 하였다.In more detail, in forming the midsole 1 as shown in FIG. 1, in the main surface of the midsole, the wheel wheel part 3 higher than the bottom surface 2 is melted to form a contour. As shown in Fig. 2, the wing piece 3a is applied to the main surface of the sponge plate 2a, which is made of material, by grinding and cutting, or is temporarily fabricated by attaching a separate outline to the post-processing post molding. The product was completed.

따라서 이러한 종래의 돌륜부 성형방법은 스펀지 소재판의 예비가 공이 지극히 비능룰적이고 가공에 따른 인력이 많이 소요되어 가공비가 고가하므로 신발의 코스트앙등의 큰 요인이 되었다.Therefore, in the conventional wheel forming method, since the preliminary processing of the sponge material sheet is extremely inefficient and requires a lot of manpower according to the processing, the processing cost is high, which is a large factor such as cost of shoes.

본 발명은 이러한 종래의 폐단에 착안하여 스펀지판소재를 포스트몰딩에 의하여 돌륜부를 성형시키되, 특히 진공성형법에 의하여 종래와 같은 돌륜부를 성형을 위한 일체의 예비적 가공이 불필요하게 한데 특징이 있다.The present invention focuses on these conventional closed ends to form a wheel wheel part by post-molding a sponge plate material, and in particular, by vacuum forming method, there is no need for any preliminary processing for molding the wheel wheel part as in the prior art.

다시 말하면 본 발명은 제단된 스펀지판을 진공금형에 내입하여 포스트몰딩하므로서 신발중창의 돌륜부와 진공압에 의하여 정확한 규격으로 성형되도록 한 것으로 이하 본 발명의 구성과 효과를 더욱 상세하게 설명하면 다음과 같다.In other words, the present invention is to be molded to the exact specification by the wheel wheel and the vacuum pressure of the sole of the shoe by inserting the emulsified sponge plate into the vacuum mold and post-molding will be described in more detail below the configuration and effect of the present invention same.

신발중창(1)의 후반부측 주면에 바닥면(2) 보다는 약간 더 높은 돌륜부(3)를 융설시킴에 있어서, 본 발명은 제3도와 같은 신발형태를 이루는 평면 스펀지판(1a)을 소재로 하고 제4도 및 제5도와 같은 진공금형 장치를 이용한다. 금형장치는 신발형태의 성형실(6)을 갖는 하부금형(4)에 상기 성형실(6)에 돌출내입되는 융기부(7)를 갖는 상부금형의 결합으로 되고 융기부(7)의 주면에는 중창(1)의 돌륜부 (3)와 꼭 일치되는 돌륜부 성형실(8)을 형성한다.In melting the wheel part 3 slightly higher than the bottom surface 2 on the main surface of the rear half of the shoe sole 1, the present invention uses a flat sponge plate 1a that forms the shoe shape as shown in FIG. And a vacuum mold apparatus as shown in FIGS. 4 and 5. The mold apparatus is a combination of an upper mold having a ridge portion 7 protruding into the molding chamber 6 to a lower mold 4 having a shoe shape molding chamber 6 and a main surface of the ridge portion 7. The wheel part shaping | molding chamber 8 which exactly matches the wheel part 3 of the midsole 1 is formed.

그리고 금형실(6)의 주면에는 제5도의 사시도에 예시한 바와 같이 성형실내의 공기를 빨아낼 수 있는 진공통로(9)를 요설하여 외부측에 연결한 공급흡출관 (11)과 제4도와 같이 연통되도록 설치하고 이 진공통로(9)의 진공압을 보존하기 위하여 외부공기와는 차단되는 패킹링(10)을 상기 진공통로(9)의 주면에 환설시키는 구성으로 된다.In addition, as shown in the perspective view of FIG. 5, the main surface of the mold chamber 6 is provided with a vacuum passage 9 capable of sucking air in the molding chamber and connected to an external side. In order to communicate with each other and to preserve the vacuum pressure of the vacuum passage (9) is configured to replace the packing ring 10 to the main surface of the vacuum passage (9) which is blocked from the outside air.

이상과 같이 된 본 발명은 중창의 소재(1a)는 상기 금형의 성형실(6)에 알맞게 내입되는 반가류 상태의 평면 스펀지판 소재를 이용하므로 종래와 같이 돌륜부 성형을 위한 예비가공을 일체 필요로 하지 않는다. 이는 제4도의 공정도에 따라 설명하면 반가류상태의 중창 성형소재(1a)를 금형실(6)에 내입하여 상부금형(5)을 꼭 눌러 덮는다.According to the present invention as described above, since the material 1a of the midsole uses a flat sponge plate material in a semi-vulcanized state suitably inserted into the molding chamber 6 of the mold, preliminary processing for forming the wheel part is required as in the prior art. Do not When this is explained according to the process diagram of Fig. 4, the midsole molded material 1a in a semi-vulcanized state is introduced into the mold chamber 6 to cover the upper mold 5 by pressing it.

이때 금형의 온도는 120-180℃의 범위이고 상하부 금형은 크립장치를 이용하여 폐소강도를 충분히 유지시킨 상태에서 공기 흡출관(11)을 통하여 성형실(6)내의 공기를 밖으로 흡출시킨다. 진공압에서 머무는 성형시간은 약 5-10분 정도가 적당하다.At this time, the temperature of the mold is in the range of 120-180 ° C and the upper and lower molds suck out the air in the molding chamber 6 through the air draft tube 11 while maintaining the closed strength sufficiently using a creep device. Molding time of staying in vacuum is suitable about 5-10 minutes.

이렇게 되면 반가류상태의 스펀지 성형소재(1a)는 적정온도에서 가류가 진행됨과 동시에 성형실(6)내의 높은 진공압에 의하여 성형소재(1a)의 가장자리 주면은 능동적으로 돌륜부 성형실(8)쪽으로 융기되어 전체 성형실(6)은 성형소재(1a)가 빈틈없이 일정한 분포로서 충진된 포스트 몰딩상태가 된다.In this case, the semi-vulcanized sponge-forming material 1a undergoes vulcanization at an appropriate temperature, and at the same time, the edge main surface of the molding material 1a is actively directed toward the wheel forming chamber 8 by the high vacuum pressure in the molding chamber 6. It is raised and the whole shaping | molding chamber 6 is in the state of the post molding by which the molding material 1a was filled in a uniform distribution.

이와 같이 된 진공압이 걸린 상태에서 금형전체를 냉각실로 옮겨서 5-10분 정도 냉각하면 내부의 성형소재(1a)는 진공압에 의해 돌륜부 성형실(8)까지 융기된 상태에서 고정되어 냉각이 이루어진다. 냉각이 완료된 후 진공압을 해제하고 금형을 개방하며 성형소재(1a)는 반가류 상태에서 테두리 부분에 돌륜부(3)가 일체적으로 융설된 상태에서 완전 가류되어 제1도와 같은 완제품의 중창이 얻어진다.When the entire mold is transferred to the cooling chamber and cooled for about 5-10 minutes while the vacuum pressure is applied as described above, the internal molding material 1a is fixed in the raised state to the wheel forming chamber 8 by vacuum pressure and cooling is performed. Is done. After the cooling is completed, the vacuum pressure is released and the mold is opened. The molding material 1a is completely vulcanized in the state in which the wheel part 3 is integrally melted in the edge portion in the semi-vulcanized state, so that the midsole of the finished product as shown in FIG. Obtained.

본 발명에 의한 신발중창 성형방법은 다음과 같은 유리한 잇점이 있다.The shoe sole molding method according to the present invention has the following advantages.

첫째 : 성형소재(1a)는 종래와 같이 돌륜부(3) 형성을 위한 연삭이나 별도의 돌륜편을 부착하여 주는 복잡한 선행공정이 전혀 필요없이 진공압에 의한 재료 팽창압력으로 돌륜부(3)가 형성되므로 중창의 제조공정의 간편성, 제조공비의 현저한 절감효과가 있고,Firstly, the molded material 1a is formed by the material expansion pressure by vacuum pressure without any complicated prior steps for grinding or attaching a separate wheel piece for forming the wheel part 3 as in the prior art. Because it is formed, there is a significant savings in the manufacturing process, manufacturing cost of the midsole,

둘째 : 금형압에 의하여 돌륜부(3)가 강제적으로 형성되는 것이 아니고 진공압에 의하여 성형소재(1a)가 스스로 능동적으로 돌륜부 성형실(8)쪽으로 밀려들어가 돌륜부(8)를 형성하므로 금형의 형태 문양과 항상 정확하게 일치되는 규격제품을 얻을 수 있어 불량품의 발생이 거의 일어나지 않는다.Second: The mold wheel 3 is not forcibly formed by the mold pressure, but the molding material 1a is actively pushed toward the wheel forming chamber 8 by the vacuum pressure to form the wheel wheel 8, thereby forming a mold. It is possible to obtain a standard product that always exactly matches the shape pattern of the product, so that the generation of defective products rarely occurs.

셋째 : 성형금형은 개별적으로 진공압이 걸리는 매우 합리적인 구조를 가지고 있어 제품의 양산효율이 신장되고 금형의 구조가 간단하여 금형비를 크게 앙등시킴이 없이 소정의 제품을 양산할 수 있는 효과가 있다.Third: The molding mold has a very reasonable structure to take vacuum pressure individually, so that the mass production efficiency of the product is increased and the structure of the mold is simple, so that a predetermined product can be mass-produced without greatly raising the mold cost.
