Title: Method and apparatus for detection of intensified differential pressure of hydraulic cylinder
Inventor: FUJINO KIYOSHI
IPC: B29C45/82
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To detect the intensified differential pressure of a hydraulic cylinder by a method in which the front hydraulic pressure and the rear hydraulic pressure of a check valve are connected respectively to hydraulic pressure chambers on both sides of a case which has mutually identical areas at both ends and in which a slidable spool is built. SOLUTION: The front hydraulic pressure PC and the rear hydraulic pressure PCO of a check valve 31 in a hydraulic pressure line pressurized by a mold locking cylinder are guided respectively to a hydraulic pressure chamber 4b and a hydraulic pressure chamber 4c on both sides of a case. A molten metal is filled and pressurized into a mold cavity by using an injection plunger. When its mold opening force becomes larger than a mold closing force, a ram at the mold closing cylinder is going to retreat, the hydraulic pressure inside the mold closing cylinder is intensified, but it does not flow backward because the check valve 31 exists. When the hydraulic pressure is guided to the hydraulic pressure chamber 4b on one side of a differential pressure detector 1 via a hole 10, a spool 2 overcomes the force of a spring 5 so as to be moved due to a a pressure difference.  Its movement amount is detected by a differential transformer 8 for displacement-degree detection so as to be computed, and an intensified differential pressure is detected.
