By using the regulator 16 made in a vacuum state to maintain the blocking state with the fifth solenoid valve 38.
상기한 제5솔레노이드 밸브(38)로 제2챔버내(36)이 차단상태가 유지됨으로써 제1하우징(10)에 설치된 조정기(16)를 작동시켜 제1하우징(10)과 제2하우징(30)에 설치된 제3,4솔레노이드밸브(23)(32)를 연결관(24)으로 연결하여 연통되게 설치한다.As the fifth solenoid valve 38 maintains the state in which the second chamber 36 is blocked, the regulator 16 installed in the first housing 10 is operated to operate the first housing 10 and the second housing 30. The third and fourth solenoid valves (23) and (32) are installed in the c) by connecting to the connecting pipe (24) and installed in communication.
상기한 제1하우징(10)과 제2하우징(30)을 연결 설치하도록 설치된 제3,4솔레노이드밸브(23)(32)를 동시에 개구하여 대기압 상태인 제1챔버(14)와 진공상태인 제2챔버(36)를 서로 연결시킴으로써 깔대기(13)에 담겨진 액상수지가 제1챔버(14)와 제2챔버(36)내의 압력차에 의해 제1연통관(22)과 연결관(24) 그리고 제2연통관(33)을 통해 몰드부재(35)내의 캐비티(35C)에 충진되도록 함으로서 주조제품을 성형할 수 있게 한다.The first and second solenoid valves 23 and 32, which are installed to connect and install the first housing 10 and the second housing 30, are simultaneously opened, and the first chamber 14 in the atmospheric pressure state and the vacuum agent By connecting the two chambers 36 to each other, the liquid resin contained in the funnel 13 is formed by the pressure difference between the first chamber 14 and the second chamber 36. By filling the cavity 35C in the mold member 35 through the two communicating tubes 33, it is possible to mold the cast product.
[발명의 효과][Effects of the Invention]
이러한 본 발명은 사출 금형의 대체공법으로서 수지계 성형법의 하나로 칩 또는 분말을 녹여서 사출하여 일정한 형틀에 넣어 대형의 부품을 성형이 용이한 효과가 있다.The present invention has an effect of easily molding a large part by dissolving chips or powders and injecting them into a mold by dissolving chips or powders as one of resin-based molding methods as an alternative method for injection molds.
또한 대형 부품의 제작에 따른 시간이 많이 소모되지 않고, 수지의 진공 가압됨으로써 성형의 정확도가 상승하게 되는 효과가 있다.In addition, it does not consume much time due to the manufacture of large parts, and there is an effect that the accuracy of molding is increased by vacuum pressing of the resin.
이에 따라 진공주형의 가압장치에 의한 수지의 성형은 제작비가 저렴해지고 이에 따라 원가 절감이 이루어지는 효과가 발생하는 유용한 발명이다.Accordingly, the molding of the resin by the pressurization device of the vacuum mold is a useful invention in which the manufacturing cost becomes low and thus the cost is reduced.
