Embodiment of the present utility model is related to hydraulic protecting loop in a kind of double-plate matched mould machine lifting process, such as schemes
Shown in 13, including hoist cylinder 1, two-position four-way deadweight safety valve 2 and inserted valve 7, described hoist cylinder 1 has four,
The rod end of four hoist cylinders 1 is connected with one end of fuel tank by pipeline, the rear end of four hoist cylinders 1 pass through pipeline with
The side port of inserted valve 7 connects, and the lower ending opening of inserted valve 7 is connected with the fuel tank other end, two in four hoist cylinders 1
Two-position four-way deadweight safety valve 2, hoist cylinder 1 are provided with the pipeline that hoist cylinder 1 rear end is connected with other hoist cylinders 1
Rear end is connected with the b mouth of two-position four-way deadweight safety valve 2 by pipeline, and the t mouth of two-position four-way deadweight safety valve 2 passes through pipeline
Form loop with b mouth, the p mouth of two-position four-way deadweight safety valve 2 passes through pipeline and forms loop, two-position four-way hydraulic safe with a mouth
The p mouth of valve 2 is connected with the lateral opening of inserted valve 7, and a of pipeline and bi-bit bi-pass hydraulic valve 6 is passed through in described inserted valve 7 upper end
Mouthful it is connected, the p mouth of bi-bit bi-pass hydraulic valve 6 is connected with inserted valve 7 side port, the t mouth of bi-bit bi-pass hydraulic valve 6 and fuel tank phase
Connect, and the mouth of pipe is located above fuel tank liquid level.
The described push rod of hoist cylinder 1 is connected with tank bottoms 8.
Described two-position four-way deadweight safety valve 2 side is provided with single-acting Electromagnetic Control 4, and opposite side is provided with pressure and continues
Electrical equipment 3.

On the pipeline that the described rear end of hoist cylinder 1 is connected with inserted valve 7, flexible conduit 9 is installed.
Embodiment
1st, close under door state, during normal work, because two two-position four-way deadweight safety valves 2 and check valve 5 are all to open
State, clapper die spotting press moves up and down and is not affected.
2nd, template rises, and bi-bit bi-pass hydraulic valve 6 must not be electric, and now, similar to non-return valve function, oil cylinder can only for inserted valve 7
Rise it is impossible to decline.When this function can be risen with effectively solving template midway, the problem that template moment declines, safer.
When the 3rd, opening the door, two two-position four-way deadweight safety valves 2 and bi-bit bi-pass hydraulic valve 6 power-off, the no bar of hoist cylinder 1
Through inserted valve 7, the rodless cavity UNICOM of inserted valve 7 epicoele guide oil and hoist cylinder 1, due to cavity area on inserted valve 7 for chamber oil return
Greatly, now inserted valve 7 is closed, and so that the oil return of hoist cylinder 1 cannot be discharged, template will not decline, two four simultaneously
The valve element of logical deadweight safety valve 2 feeds back it is ensured that template does not decline all the time in good time.
4th, because two-position four-way deadweight safety valve 2 controls the oil inlet and oil return of single oil cylinder, traffic requirement is not high, and using double fluid
Road designs, and substantially reduces two-position four-way deadweight safety valve 2 latus rectum, and two-position four-way deadweight safety valve 2 is that four oil cylinders are diagonal
Arrangement, while ensureing safe, decreases cost.
