Description
본 발명은 신발창 및 신발창 제조방법에 관한 것으로서, 특히 안창과 겉창을 접착방법이 아닌 하나의 금형내에서 간단한 공정에 의해 일체로 접합시켜 가공된 신발창 및 제조방법에 관한 것이다.The present invention relates to a shoe sole and a shoe manufacturing method, and more particularly, to a shoe sole and a manufacturing method that is integrally bonded and processed by a simple process in one mold rather than the insole and the outsole.
일반적으로 신발창은 안창과 겉창으로 구성되어진다. 이때 안창과 겉창은 각기 다른 금형에서 제조되어 안창에 접착제를 도포하고 그 상단에 겉창을 부착하여 장시간 가압시켜 상호 접착시켜 신발창을 구성하여 왔다.In general, a shoe sole consists of an insole and an outsole. At this time, the insole and the outsole are manufactured in different molds to apply an adhesive to the insole and attach the outsole to the top of the insole for a long time by mutual bonding to form a shoe sole.
이때 겉창은 파이로이나 폴리우레탄, PVC 등을 사용하는데 이들을 판형태로 미리 생산한 후 프레스 금형을 통해 프레싱하여 치수별로 생산하는데 소재 자체의 생산공정이 번거로웠다.At this time, the outsole uses pyro, polyurethane, PVC, etc., and these are produced in advance in the form of a plate and then pressed through a press mold to produce by dimension, the production process of the material itself was cumbersome.
그리고 무발포층인 안창은 주로 고무(천연고무+합성고무)가 많이 사용되는데 이는 고무성형 금형에서 미리 치수별, 형태별, 색상별로 생산한다.In addition, rubber (natural rubber + synthetic rubber) is mainly used for insole, which is a non-foaming layer, which is produced by dimension, shape, and color in advance in rubber molding mold.
상기와 같이 각각 별도로 생산된 겉창과 안창은 접착제를 사용하여 서로 접착시켜 신발창을 완성시키는데, 상기와 같은 접착방법에 의해 생산하는 것은 생산비용이 많이 소요되는 문제가 있고, 또한 그 공정이 번거로워 생산성이 저하되는 문제와 이로 인해 생산 단가가 상승되는 문제가 있다.The outsole and insole produced separately as described above are bonded to each other using an adhesive to complete the shoe sole, the production by the above bonding method has a problem that the production cost takes a lot, and the process is cumbersome and productivity There is a problem of deterioration and thereby a production cost increase.
특히, 접착방법에 의해 가공된 신발창은 시간이 경과되면 접착력이 저하되어 안창과 겉창이 쉽게 분리되어 그 기능을 제대로 발휘하지 못하는 문제가 있다.In particular, the shoe sole processed by the adhesive method has a problem that the adhesive strength is deteriorated over time, so that the insole and the outsole is easily separated and does not properly exhibit its function.
이러한 문제는 제품에 대한 소비자의 신뢰성이 저하되는 문제와 구매의욕이 저하되는 문제가 있다.These problems have a problem that the consumer's reliability of the product is lowered and the purchase intention is lowered.
본 발명은 상기한 바와 같이 종래에서 야기되는 문제점을 해결하기 위한 것으로서, 하나의 금형내에서 겉창과 안창을 일체로 성형가공하여 하나의 신발창을 완성시킴으로서 생산성을 향상시킴과 동시에 생산 단가를 낮출 수 있고 상품의 신뢰성을 극대화시키는 신발창을 제공하는데 그 목적이 있다.The present invention is to solve the problems caused in the prior art as described above, by molding the outsole and the insole integrally in one mold to complete one shoe sole to improve productivity and at the same time lower the production cost The purpose is to provide a shoe sole that maximizes the reliability of the product.
상기한 목적을 달성하기 위한 본 발명의 신발창은 하나의 금형틀 내로 안창의 소재와 겉창의 소재를 주입하여 열 융착에 의해 일체로 가공하여 이루어진 것에 그 특징이 있다.The sole of the present invention for achieving the above object is characterized by being made by integrally processing by heat fusion by injecting the material of the insole and the material of the outsole into one mold.
상기한 목적을 달성하기 위한 본 발명의 신발창 제조방법은, 금형틀 내부 겉창 성형부로 액상의 발포성수지원료를 주입하는 제1단계와; 금형틀 내부 안창 성형부로 액상의 무발포성수지원료를 주입하는 제2단계와; 상기 금형틀의 상측으로 가압금형을 결합하는 제3단계와; 주입된 원료를 가열수단으로 보내어 가열하는 제4단계와; 상기 제 4단계를 통과한 원료를 냉각시키는 제5단계;를 포함하여 것에 그 특징이 있다.The sole manufacturing method of the present invention for achieving the above object, the first step of injecting a liquid foamable water support material into the mold outsole inner mold; A second step of injecting a liquid non-foamable water support material into the mold insole molding unit; A third step of coupling the pressing mold to the upper side of the mold; A fourth step of heating the injected raw material by heating means; And a fifth step of cooling the raw material that has passed the fourth step.
상기한 발명은 하나의 금형내에서 겉창과 안창을 일체로 성형가공하여 하나의 신발창을 완성시킴으로서 생산성을 향상시킴과 동시에 생산 단가를 낮출 수 있고 상품의 신뢰성이 극대화되는 효과를 가지고 있다.The invention described above has the effect of maximizing productivity and lowering the production cost and maximizing the reliability of goods by completing the sole and insole in one mold to complete one shoe sole.
이하에서, 본 발명의 실시예가 기술된다.In the following, embodiments of the present invention are described.
하기에서 본 발명을 설명함에 있어서, 관련된 공지 기능 또는 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명은 생략될 것이다. 또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 설정된 용어들로서 이 용어들은 제품을 생산하는 생산자의 의도 또는 관례에 따라 달라질 수 있으며, 용어들의 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In the following description of the present invention, if it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted. In addition, the terms to be described below are terms set in consideration of functions in the present invention, and these terms may vary according to the intention or custom of the producer producing the product, and the definition of the terms should be made based on the contents throughout the present specification. .
첨부 도면 도 1에 도시된 바와 같이, 도 1은 본 발명에 따른 신발창의 구조를 설명하기 위한 단면도로서, 본 발명의 신발창(10)은 안창(20)의 바닥면으로 겉창(30)이 열융착에 의해 일체로 성형되어 구성된다.As shown in Figure 1, Figure 1 is a cross-sectional view for explaining the structure of the sole according to the present invention, the sole 10 of the present invention is the bottom surface of the
이때, 안창(20)은 발포성수지로 이루어지며, 겉창(30)은 무발포성수지로 이루어진다. 상기 발포성수지 또는 무발포성수지는 폴리우레탄으로 이루어지는 것이 바람직하다.At this time, the
상기와 같이 안창(20)과 겉창(30)은 열 융착 및 냉각에 의하여 일체로 구성 된다.As described above, the
그리고, 상기 안창(20)에는 에어펌프수납공(21)과 에어주입공(22) 및 통기공(23)이 연통되게 형성되며, 상기 에어 수납공(21)으로는 에어펌프(40)가 수납되어 이루어진다.In addition, the
상기 에어펌프(40)를 가압함에 의하여 에어펌프(40)에서 에어가 나와 에어주입공(22)을 통해 통기공(23)을 향하도록 구성된다.By pressurizing the
또한, 가압에 의해 발생되어 순환된 에어는 에어펌프(40)의 팽창됨에 의해 에어를 주입되었던 에어가 신발창(10)의 바깥쪽으로 배출되게 구성된다.In addition, the air generated and circulated by the pressurized air is configured such that the air that has been injected with air is expelled to the outside of the sole 10 by the expansion of the
한편, 첨부 도면 도 2는 본 발명의 신발창 제조방법의 흐름도이다.On the other hand, Figure 2 is a flow chart of a shoe sole manufacturing method of the present invention.
제1단계는, 금형틀 내부의 겉창 성형부로 액상의 발포성수지원료를 주입하는 단계이다.The first step is a step of injecting a liquid foamable water support material into the outsole molding portion inside the mold.
제 2단계는, 상기와 같이 겉창 성형부로 발포성수지원료를 주입한 후 그 위에 안창을 소재를 이루는 액상의 무발포성수지원료를 주입하는 단계이다.The second step is injecting the foamable water support material into the outsole molding portion as described above, and then injecting the liquid non-foamable water support material forming the insole thereon.
이때, 겉창 및 안창의 발포성수지 및 무발포성수지는 폴리우레탄으로 구성함이 바람직하다.At this time, the foamed resin and the non-foamable resin of the outsole and the insole is preferably composed of polyurethane.
그리고 겉창과 안창의 소재가 액상으로 경계면부에서는 서로 혼합되어진다.And the outsole and insole materials are mixed with each other in the interface at the liquid phase.
제 3단계는, 1, 2단계에 의해 원료재를 주입한 상태에서 가압금형을 결합하는 단계이다.The third step is a step of combining the press mold in the state in which the raw material is injected by the first and second steps.
이때, 내부에 주입된 액상의 원료는 상하부금형에 의해 그 형태로 형상을 갖추게 된다.At this time, the liquid raw material injected therein is shaped in the form by the upper and lower molds.
제4단계, 주입된 액상의 소재는 가열수단으로 옮겨져 상온에서 경화되도록 방치하는 단계이다.In the fourth step, the injected liquid material is transferred to a heating means and left to cure at room temperature.
제5단계, 상호 경화된 소재를 가압금형을 해지하여 오픈하면 서서히 냉각되며, 어느 정도 냉각된 후 금형틀에서 일체로 성형된 신발창을 꺼내는 단계이다.In the fifth step, the cross-cured material is released by opening the pressure mold and gradually cooled, and after cooling to some extent, the shoe sole integrally molded from the mold is taken out.
상기와 같이 본 발명의 신발창은 겉창과 안창이 일체로 성형가공되기 때문에 상호 분리되는 것을 방지되고, 또한, 겉창에 의해 신발이 미끄러지는 것이 방지된다. As described above, the sole of the present invention is prevented from being separated from each other because the outsole and the insole are integrally molded, and the shoe is prevented from slipping by the outsole.
또한, 본 발명은 신발창을 제조함에 있어, 간단한 가공에 의해 겉창과 안창을 일체로 성형가공하는 방법으로 신발창의 생산성을 향상시킬 수 있고, 신발 제조단가를 낮추어 제공할 수 있는 장점을 가지고 있다.In addition, the present invention in the manufacture of a shoe sole, by the process of integrally molding the outsole and the insole by a simple process can improve the productivity of the sole, has the advantage that can be provided by lowering the shoe manufacturing cost.
