그러나 선출원 기술은 형결합 및 분리시 작업자가 별도의 클램핑실린더에 의해 클램핑블록을 전후 작동하여 설치하는 작업으로 작업성이 불편하게 됨은 물론 이로인해 성형을 위한 싸이클타임이 길게 되어 생산성이 저하되는 문제를 갖게 된다.However, the prior application technology is a problem that the worker is uncomfortable with the operation of installing the clamping block back and forth by a separate clamping cylinder during mold joining and disassembly, and this leads to a problem that productivity is reduced due to a long cycle time for molding. Will have
또한 상기 하금형을 승하강작동시키기 위한 실린더외에 클램핑실린더의 구비로 전체전인 제조단가를 상승시키게 된다.In addition, with the provision of a clamping cylinder in addition to the cylinder for raising and lowering the lower die, the overall manufacturing cost is increased.
본 고안은 상기한 종래기술과 본 출원인에 선출원된 기술이 갖는 제반문제점을 해결하고자 안출된 것으로서, 금형의 형결합 및 분리, 진공챔버의 이동작동이 간단하게 이루어짐은 물론 그 싸이클타임을 단축하여 작업성 및 생산성을 우수하게 제공하는데 그 목적이 있다.The present invention was devised to solve all the problems of the prior art and the applicant filed by the present applicant, the mold coupling and separation of the mold, the movement operation of the vacuum chamber is made simple, as well as shortening the cycle time The purpose is to provide excellent performance and productivity.
또한 본 고안은 상기 하금형을 승하강시키위한 실린더의 구비를 최소화하여 제조단가를 절감하게 되는데 그 목적이 있다.In addition, the present invention aims to reduce the manufacturing cost by minimizing the provision of the cylinder for raising and lowering the lower die.

즉, 본 고안은 도 1 및 도 4에 도시된 바와같이, 원료공급기(5)와 사출기(7)가 설치된 상부프레임(10)의 하단에 상금형(A)과 승하강작동하는 진공챔버(20)를 설치하고, 그 하부에는 하금형(B)이 장착되는 하부프레임(30)이 메인프레임(40)상에 설치되어 실린더의 작동으로 승하강작동하면서 형결합 및 분리하는 진공 고무사출성형기에 있어서,That is, the present invention, as shown in Figure 1 and 4, the raw material feeder 5 and the vacuum chamber 20 to move up and down the upper mold (A) at the lower end of the upper frame 10 is installed In the vacuum rubber injection molding machine for installing and lowering the lower frame (30) is installed on the main frame 40, the lower frame (30) is installed on the main frame (40) while the lifting and lowering operation by the operation of the cylinder. ,
상기 메인프레임(40)상에는 유압 주입구(46a)를 갖는 유압작동실(46)을 내부에 형성한 하우징(45)을 설치하고, 그 상부의 하부프레임(30)상에는 메인피스톤로드(35)를 돌설하여 상기 메인피스톤로드(35)가 유압작동실(46)에서 사이드실린더(42)에 의한 승하강작동과 함께 유압주입구(46a)로 공급되는 유압에 의해 승하강 작동하면서 하부프레임(30)을 승하강작동시키도록 이루어진다.On the main frame 40, a housing 45 having a hydraulic operation chamber 46 having a hydraulic injection hole 46a therein is installed, and a main piston rod 35 protrudes on the lower frame 30 thereon. The main piston rod 35 lifts and lowers the lower frame 30 while lifting and lowering by hydraulic pressure supplied to the hydraulic inlet 46a together with the lifting and lowering operation by the side cylinder 42 in the hydraulic operation chamber 46. It is made to operate down.
이때 상기 메인피스톤로드(35)는 하부프레임(30)과 일체형으로 제작할수 있음은 물론 분리형으로 제작하여 별도의 체결볼트(36)로 결합할수 있게 된다.At this time, the main piston rod 35 can be manufactured integrally with the lower frame 30, as well as a separate type can be combined with a separate fastening bolt (36).
또한 상기 메인피스톤로드(35)와 하부프레임(30)은 키(38)로서 상호 맞물리게 조립되어 그 회전방향으로의 유동을 방지하게 된다.In addition, the main piston rod 35 and the lower frame 30 are assembled to each other as a key 38 to prevent the flow in the rotation direction.
한편, 상기 상부프레임(10)의 하부에 설치된 진공챔버(20)도 유압 실린더(25)에 의해 유압으로 승하강작동하도록 하게 된다.On the other hand, the vacuum chamber 20 installed in the lower portion of the upper frame 10 is to be moved up and down hydraulically by the hydraulic cylinder (25).
미설명부호로서, 50은 유압공급부, 46b는 유압작동실(46)의 하부에 형성되어 유압이 메인피스톤로드(35)의 원주상으로 고르게 공급되도록 형성된 유도홈, 32는 형이송실린더를 나타내는 것이다.As the reference numeral 50, the hydraulic supply portion 46b is formed in the lower portion of the hydraulic operation chamber 46, the guide groove formed so that the hydraulic pressure is evenly supplied on the circumference of the main piston rod 35, 32 represents the mold transfer cylinder. .
이와같이 구성된 본 고안의 작용 및 작동에 대해 설명하면 다음과 같다.Referring to the operation and operation of the present invention configured as described above are as follows.
먼저, 상하금형(A)(B)을 장착한 상태에서, 사이드실린더(42)를 신장시키는 것에 의해 하금형(B)이 설치된 하부프레임(30)을 신속하게 1차 상승시켜 상하금형(A)(B)이 일정 간격으로 근접되게 한다.First, in the state where the upper and lower molds (A) and (B) are attached, the lower frame (30) on which the lower mold (B) is installed is quickly raised first by extending the side cylinder (42), and the upper and lower molds (A). Let (B) be approached at regular intervals.
이때 상기 하부프레임(30)의 하부에 설치된 메인피스톤로드(35)가 유압작동실(46)을 따라 안내되며 상승하게 된다.At this time, the main piston rod 35 installed in the lower portion of the lower frame 30 is guided along the hydraulic operation chamber 46 and ascended.
이와같은 상태에서 유압공급부(50)에서 하우징(45)의 유압주입구(46a)를 통해 유압작동실(46)로 유체를 공급하게 된다.In this state, the fluid is supplied from the hydraulic supply unit 50 to the hydraulic operation chamber 46 through the hydraulic inlet 46a of the housing 45.
이와같이 유압작동실(46)로 공급되는 유체압에 의해서 상기 메인피스톤로드(35)는 다시 2차 상승을 하게 된다.As such, the main piston rod 35 rises again by the fluid pressure supplied to the hydraulic operation chamber 46.
이와같은 메인피스톤로드(35)의 2차상승으로 하부프레임(30)과 상부프레임(10)에 대향 설치된 상하금형(A)(B)의 형결합이 이루어진게 된다.As a result of the secondary rise of the main piston rod 35, the upper and lower molds A and B are installed on the lower frame 30 and the upper frame 10, respectively.
이와같이 형결합이 이루어지면, 진공챔버(20)를 하강시켜 상하금형(A)(B)을 밀폐시키게 되고, 진공펌프(미도시)의 작동에 의해 그 내부의 진공상태를 유지하게 된다.When the mold coupling is made in this way, the vacuum chamber 20 is lowered to seal the upper and lower molds (A) and (B), thereby maintaining the vacuum state therein by the operation of a vacuum pump (not shown).
이때 상기 진공챔버(20)는 유압공급부(50)에 의해 공급되는 유압으로 유압실린더(25)를 작동시켜 승하강작동시키게 된다.At this time, the vacuum chamber 20 is operated by the hydraulic cylinder 25 by the hydraulic pressure supplied by the hydraulic supply unit 50 to move up and down.
상기와같이 진공챔버(20)내부가 진공상태를 이루면, 원료공급기(5)에서 공급된 소재를 사출기(7)의 성형노즐을 통해 금형(A)(B)내에 사출하여 성형하게 된다.When the inside of the vacuum chamber 20 is in a vacuum state as described above, the material supplied from the raw material supplier 5 is injected into the molds A and B through the molding nozzle of the injection machine 7 to be molded.
이와같이 성형작업이 완료되면, 상기 진공챔버(20)가 유압실린더(25)에 의해 상승하고, 또한 상기한 상승과정과 역순으로 하금형(B)이 장착된 하부프레임(30)은 하우징(45)의 유압작동실(46)내 유압을 회수함과 함께 사이드실린더(42)를 수축하므로 하강하게 된다.When the molding operation is completed in this way, the vacuum chamber 20 is raised by the hydraulic cylinder 25, and the lower frame 30 in which the lower mold B is mounted in the reverse order to the above-mentioned ascending process is the housing 45. The hydraulic pressure in the hydraulic operation chamber 46 is recovered, and the side cylinder 42 is contracted to descend.
이와같이 하강된 하부금형(B)은 형이송실린더(32)에 의해 이젝터장치(8)로 이동시켜 성형품을 추출하게 되는 것이다.The lower mold B thus lowered is moved to the ejector device 8 by the mold transfer cylinder 32 to extract the molded article.
이상에서 살펴본 바와같이 본 고안은 하부프레임이 사이드실린더에 의한 승하강작동과 유압에 의한 승하강작동으로 형결합 및 개방하도록 하므로 본 출원인의 선출원에서와 같이 별도의 클램핑블록을 설치하고 해제하는 작업이 배제되어 그 작업이 간단하게 됨은 물론 그로인한 싸이클타임이 단축되어 생산성이 우수하게 되고,As described above, the present invention allows the lower frame to be coupled and opened by lifting and lowering operation by side cylinder and lifting and lowering operation by hydraulic pressure, so that the operation of installing and releasing a separate clamping block as in the applicant's prior application is Not only simplify the operation, but also shorten the cycle time resulting in excellent productivity,
또한 상기 하금형을 승하강시키위한 실린더의 구비를 최소화하여 제조단가를 절감하게 되는 효과를 갖게 되는 것이다.In addition, to minimize the provision of the cylinder for raising and lowering the lower die will have the effect of reducing the manufacturing cost.
