본 고안은 사출성형기의 유압장치에서 통상사용되는 모우터의 마력보다 적은 용량의 모우터로서 소정의 유압을 올릴 수 있는 절전형 유압장치에 관한 것이다.The present invention relates to a power-saving hydraulic device capable of raising a predetermined hydraulic pressure as a motor having a capacity less than that of a motor normally used in the hydraulic device of an injection molding machine.
종래의 유압장치로서 소정의 압력을 올리기 위해서는 어느압력 이상에서 소정의 압력을 올리기까지에는 모우터에 많은 부하가 걸리므로 이 과부하에 맞는용량이 큰 모우터를 사용해야만 되었으므로 많은 동력이 소모되었다.In order to raise a predetermined pressure as a conventional hydraulic device, since a large load is applied to the motor until a predetermined pressure is raised above a certain pressure, a large motor suitable for this overload has to be used, which consumes a lot of power.
본 고안은 이와 같은 결점을 시정하고져 모우터에 저압벤펌프와 고압피스톤펌프를 동시에 장치하고 저압벤펌프유출구에는 유압조정장치인 솔레노이드 전자밸브를 부설시켜 어느정도 압력까지 고, 저압펌프가 동시에 압력을 올리고 그 이상에는 솔레노이드 접점을 작동시켜 저압펌프의 기름 전량이 탱크로 되돌아가서 무부하 상태로 되고 고압펌프만으로 소정의 압력을 올리도록하여 적은 용량의 모우터로서 소기의 압력을 올릴수 있는 것으로서 도면에 의거 상세히 설명하면 다음과 같다.The present invention corrects these shortcomings and installs a low pressure ben pump and a high pressure piston pump at the same time in the motor, and installs a solenoid solenoid valve, a hydraulic control device, at the low pressure ben pump outlet so that the high pressure to a certain pressure can be raised simultaneously Above that, the solenoid contact is operated so that the entire amount of oil in the low pressure pump is returned to the tank to be in a no-load state and the predetermined pressure can be raised only by the high pressure pump to raise the desired pressure as a small capacity motor. Is as follows.
모우터 양측에 저압의 벤펌프(1)와 고압의 피스톤펌프(2)을 동시에 장치시키고 저압벤펌프를 솔레노이드(11) 작동에 의해 좌, 우측으로 유동되는 스푸울(12)과 피스톤(13)을 내설한 전자밸브(10)의 유입구(14)에 연결시키고 고압펌프 연결관과 합류하는 사출유출구(15)에는 체크밸브(18)를 부착시켜 기름의 역류를 방지하였으며 탱크유출구(16)와 잔여유출구(17),(17')를 탱크(3)로 연결시켜서된 것이다.A low pressure ben pump (1) and a high pressure piston pump (2) are installed at both sides of the motor at the same time, and the low pressure ben pump is operated by the solenoid (11) to operate the sprue (12) and the piston (13). Is connected to the inlet 14 of the solenoid valve 10, and a check valve 18 is attached to the injection outlet 15 joining the high-pressure pump connecting pipe to prevent the backflow of oil, and the tank outlet 16 and the remaining The outlets 17 and 17 'are connected to the tank 3.
이와 같은 구조로된 본 고안은 모우터 양측에 저압벤펌프(1)와 고압피스톤펌프(2)를 동시에 장치시켰으므로 모우터에 의해 두펌프가 동시에 작동되므로 빠른시간내에 유압이 올라가고 유압이 오르면 과부하가 걸리므로 솔레노이드 접점을 작동시키면 솔레노이드(11)에 의해 수푸울(12)과 피스톤(13)이 좌측으로 이동되면서 피스톤이 사출유출구(15)를 폐쇄시키면서 탱크유출구(17)를 개방시킴으로 저압벤펌프(1)의 기름은 모두탱크로 되돌아 감으로 무부하 상태로 만들고 고압 피스톤펌프(2) 만으로 소정의 압력까지 올리므로 적은 용량의 모우터로도 가능하며 또한 과부하로 인한 동력소모를 방지할 수가 있으며 이때 전자밸브의 유출구(15)에 있는 체크밸브(18)는 고압피스톤펌프(2)의 유압이 역류되는 것을 막아준다.The present invention has a low pressure ben pump (1) and a high pressure piston pump (2) are installed on both sides of the motor at the same time, so the two pumps are operated simultaneously by the motor. When the solenoid contact is activated, the solenoid 11 moves the spring 12 and the piston 13 to the left side, while the piston closes the injection outlet 15 while opening the tank outlet 17 to open the low pressure ben pump. The oil in (1) is returned to the tank to make no-load state and is raised to the predetermined pressure by only the high pressure piston pump (2), so it is possible to use a small capacity motor and also to prevent power consumption due to overload. The check valve 18 at the outlet 15 of the solenoid valve prevents the hydraulic pressure of the high pressure piston pump 2 from flowing back.
사출후 솔레노이드 접점이 떨어지면 솔레노이드에 의해 스푸울과 피스톤이 우측으로 이동되면서 피스톤이 탱크 유출구(16)를 막고 사출유출구(15)를 열어주므로 저압펌프의 유압은 고압펌프의 유압과 같이 사출기로 합류하여 빠른시간내에 유압을 올리는 것이다.When the solenoid contact drops after injection, the solenoid moves the spoules and the piston to the right, and the piston blocks the tank outlet 16 and opens the injection outlet 15. Therefore, the hydraulic pressure of the low pressure pump is joined to the injection machine like the hydraulic pressure of the high pressure pump. It is to increase the hydraulic pressure in a short time.
