Description

이브이에이 신발 밑창 성형 금형{EVA shoes out sole molding metal mold}Eve shoes out sole molding metal mold {EVA shoes out sole molding metal mold}

본 발명은 EVA 신발 밑창 성형 금형에 관한 것이다.The present invention relates to an EVA shoe sole molding mold.

종래의 EVA 신발 밑창 등의 성형 금형은 프레스 열판에서 성형 금형으로 열을 공급하여 제품을 성형한 후 이를 다시 냉간 프레스로 금형을 이동하여 완전 성형될 때까지 냉각시키는 방식을 채택하고 있기 때문에 이와 같은 방식은 고온 가열 프레스에서 저온 냉간 프레스로 금형을 일일이 이동해야 하므로 많은 수의 금형(3set 이상)과 인력이 필요로 할뿐만 아니라, 이에 소요하는 작업 시간상 로스 현상이 있어 작업성 저조 등으로 생산 원가의 상승 요인이 되고 있었던 것이다.This is because the conventional molds such as EVA shoe soles adopt a method of supplying heat from a press hot plate to a molding die to form a product and then moving the mold to a cold press to cool the mold until it is completely molded. Since molds must be moved from high temperature heating presses to low temperature cold presses one by one, a large number of molds (more than 3 sets) and manpower are required. It was a factor.

본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 발명 요지는 열간 프레스 및 냉간 프레스를 거치는 성형 과정을 금형(1set)을 이용한 한번의 성형 과정(종래의 1/3)으로 가능하게 상하판에 체결된 암수 금형 내에 열간 및 냉각 공정을 실시할 수 있는 통공(1-1)(2-1)과 공실(3-1)(4-1)을 형성하여 열간 공정 시에는 스팀(약 120℃)을 주입하고 냉간 공정 시는 스팀을 수거하고 냉각수(15℃이하)를 주입할 수 있게 한 것이다.The present invention has been invented to solve the above problems, the gist of the present invention is fastened to the upper and lower plates by a single molding process (one-third conventional) using a mold (1 set) of the molding process through the hot press and cold press Through-holes (1-1) (2-1) and vacancy (3-1) (4-1) are formed in the male and female molds to perform the hot and cooling processes, and steam (approx. 120 ° C.) is injected during the hot processes. In the cold process, it is possible to collect steam and to inject cooling water (below 15 ℃).

이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.

상판(1)의 일측면에 다수의 통공(1-1)을 형성하여 외주면에 돌출 무늬(3-2)가 있는 숫 금형(3)이 대접되어진 상태에서 체결볼트(1-2)에 의해 상판(1)과 일체로 체결되면서 공실(3-1)이 형성되고, 하판(2)의 일측에도 다수의 통공(2-1)을 형성하여 외주면에 요입부(4-2)가 있는 암 금형(4)을 대접한 상태에서 체결볼트(2-2)를 하단(2)과 일체로 체결하면서 공실(4-1)이 형성되어지게 한 것이다.A plurality of through holes 1-1 are formed on one side of the upper plate 1, and the upper plate is formed by the fastening bolts 1-2 in the state that the male mold 3 having the protruding pattern 3-2 is welded on the outer circumferential surface thereof. The female mold having a recessed part 4-2 on the outer circumferential surface of the cavity 3-1 is formed while a plurality of through holes 2-1 are formed on one side of the lower plate 2 while being integrally fastened with (1). 4) in the state of the welded bolts (2-2) to the lower end (2) integrally with the vacancy (4-1) is to be formed.

이상과 같이 구성된 본 발명은 EVA 신발 밑창 성형 금형으로 사용하는 것인 바 이를 실시할 시는 도 7에 예시한 바와 같이 상하판(1)(2) 사이에 체결된 암수 금형(3)(4)의 성형실(5) 내에 EVA 등의 수지를 충전한 후 통공(1-1)(2-1)을 통해 공실(3-1)(4-1) 내에 120℃ 범위의 스팀 열을 주입하여 성형실(5)에 장입된 EVA 수지를 발포시킨 후 스팀 열의 공급을 중지함과 동시 이를 배출, 제거한 다음 통공(1-1)(2-1)을 통해 냉각수(15℃이하)를 공실(3-1)(4-1) 내에 주입하여 서서히 냉각시키면 EVA의 제품 성형이 완성되는 것이다.The present invention configured as described above is to be used as an EVA shoe sole molding mold when performing the male and female molds (3) (4) fastened between the upper and lower plates (1) (2) as illustrated in FIG. After filling the resin, such as EVA in the molding chamber 5 of the molding and injecting the steam heat of 120 ℃ range into the empty space (3-1) (4-1) through the through-hole (1-1) (2-1) After foaming the EVA resin charged into the chamber (5), the supply of steam heat was stopped and simultaneously discharged and removed, and then the cooling water (less than 15 ° C) was passed through the through holes (1-1) (2-1). 1) Injecting into (4-1) and slowly cooling completes product molding of EVA.

따라서, 1set의 금형으로서 성형품의 열간 작업과 냉간 작업을 동시에 수행할 수 있게 되는 것이다.Therefore, the hot work and the cold work of the molded article can be performed simultaneously as one set of molds.

이상과 같이 본 발명은 EVA 신발 밑창 등의 제품을 성형함에 있어 1set의 금형으로서 열간 작업과 냉간 작업을 동시에 수행할 수 있게 상하판(1)(2) 및 암수 금형(3)(4) 내에 다수의 통공(1-1)(2-1)과 공실(3-1)(4-1)을 형성하여 열간 작업시는 공실(3-1)(4-1) 내에 스팀을 공급하고, 냉간 작업 시는 공실(3-1)(4-1) 내에 냉각수로를 공급하면 되므로 구조가 간편하고 작업 시간을 대폭 단축시킬 수 있어 품질 향상과 원가 절감 등 산업 발전에 크게 기여할 수 있는 것이다.As described above, the present invention provides a plurality of molds in the upper and lower plates 1 and 2 and the male and female molds 3 and 4 to simultaneously perform hot work and cold work as one set of molds in molding products such as EVA shoe soles. Through hole (1-1) (2-1) and vacancy (3-1) (4-1) to supply steam in vacancy (3-1) (4-1) during hot work, and cold work Since the city needs to supply cooling water passages in the vacant rooms 3-1 and 4-1, the structure is simple and the work time can be greatly reduced, which can greatly contribute to industrial development such as quality improvement and cost reduction.
