Description
제1도는 본 고안의 일부를 절결한 사시도.1 is a perspective view of a part of the present invention.
제2도는 본 고안의 단면도.2 is a cross-sectional view of the present invention.
본 고안은 주로 포리우레탄수지로 되는 신방창을 제조하는 금형을 개량한데 특징이 있는 것으로 즉 신발창 제조용 금형을 에폭시수지제로 형성하되 금형의 가열시 성형 요구에 대한 전열 효과를 보다 높이기 위하여 금형의 내부에 열편을 일체로 매설한 것이다.The present invention is characterized by the improvement of the mold for manufacturing the new window mainly made of polyurethane resin, that is, forming the sole for manufacturing shoe soles made of epoxy resin, but in order to increase the heat transfer effect to the molding needs when the mold is heated Buried pieces in one piece.
일반적으로 포리우레탄수지를 이용한 신발창의 제조에 있어서는 수지 자체가 액상으로 되어 통상 60-80℃ 정도의 가교온도 만을 부여 하기만 하면 제품으로 경화 되므로 이의 금형은 높은 강도성을 필요로 하지 않게 되나, 종래에는 금형을 금속제로 만들어 금형의 외부에서 별도의 전열로서 가교온도를 부여 하였기 때문에 금형의 제작비가 많이 소요되고 전열 효과가 불량하여 열량의 낭비가 컸던 결점이 있었던 바, 본 고안은 이러한 종래의 결점을 시정한 것으로 이를 첨부 도면에 의거하여 상세히 설명하면 다음과 같다.In general, in the production of soles using polyurethane resin, the resin itself becomes a liquid and usually hardens into a product only by applying a crosslinking temperature of about 60-80 ° C., so that its mold does not require high strength. Since the mold was made of metal and the crosslinking temperature was given as a separate heat transfer from the outside of the mold, the manufacturing cost of the mold was high, and the heat transfer effect was poor. When corrected and described in detail based on the accompanying drawings as follows.
공지의 성형요입부(4)를 갖는 하금형(1) 상에 상금형(1')을 결합토록 한 것에 있어서, 이들 상, 하금형(1')(1)을 에폭시수지제로 형성하고 성형요입부(4)의 인접된 상, 하금형(1')(1)의 내부에 열편(2)(2')을 일체로 매설 하여서 된 구조이다.In the case where the upper mold 1 'is bonded onto the lower mold 1 having the well-known molding recesses 4, the upper mold and the lower mold 1' are formed of epoxy resin, It is a structure which integrally embeds the thermal strip 2 (2 ') in the upper part of the upper part and the lower mold | die 1' (1) adjacent to the mouth part 4.
도면중 미설명 부호 5,5'는 공지의 자동온도 조절기이고, 3,3'는 전원 코드선이다.In the figure, reference numeral 5, 5 'is a known thermostat, and 3, 3' is a power cord line.
이상과 같이 된 본 고안은 포리우레탄수지를 이용한 신발창의 성형에 있어서는 특별한 고압을 줄 필요가 없이 다만 60-80℃의 낮은 가교온도만을 부여 하기만 하면 족 하므로 수지류 중에서 내열성이 특출하고 강도가 높은 에폭시수지제로 하금형(1)과 상금형(1')을 형성 하더라도 제품의 성형상 하등의 지장이 없고 특히 열편(2)(2') 자체가 성형요입부(4)에 인접된 하금형(1)과 상금형(1')에 매설된 상태에 있기 때문에 자동 온도조절기(5)(5')에 의해 설정된 60-80℃의 가교 온도가 균일 하고도 효율적으로 성형요입부(4) 쪽에 전달되어 성형요입부(4)에 주입된 포리우레탄수지를 매우 능률적으로 가교시켜 제품을 양산할 수 있게 되므로 종래의 금속제로 된 금형에 비하여 금형의 제작비가 현저히 절감되고 열량의 낭비가 크게 줄어 들어 그 실용적 효과가 현저한 것이다.The present invention as described above is required to give only a low crosslinking temperature of 60-80 ℃ in the molding of a shoe sole using a polyurethane resin, so that only a low cross-linking temperature of 60-80 ℃ is excellent in heat resistance and high strength in resins Even if the lower mold (1) and the upper mold (1 ') are formed of epoxy resin, the lower mold (1) and the lower mold (1') have no problem in molding, and in particular, the lower mold (2) (2 ') itself is adjacent to the molding recess (4). 1) and the upper mold (1 '), so that the cross-linking temperature of 60-80 ℃ set by the thermostat (5) (5') is uniformly and efficiently transmitted to the molding inlet (4) side. It is possible to mass-produce the product by crosslinking the polyurethane resin injected into the molding injecting portion 4 very efficiently, which significantly reduces the manufacturing cost of the mold and greatly reduces the waste of calories compared to the conventional metal mold. Noticeable will be.
