Since the pressure is too large when many die-casting in feeding, cause the hydraulic cylinder back. HC designed and developed a self-locking cylinder device to solve this problem.

The self-locking cylinder consist of cylinder tube, front housing, back housing, piston and piston rod. The connection of front housing and back housing with the cylinder tube is thread.

HC self-locking cylinder standard bore: 40 mm, 50 mm, 63 mm. The standard length of the piston rod is in 100 mm.

The working principle of self-locking cylinder: Without lock block condition, the self-locking cylinder would not move back. So the self-locking cylinder can bear the pressure form the die casting, and the self-locking cylinder would not move back.

The self-locking cylinder is locked when the oil comes inside form the“S” port. Then the piston moves backward under the oil pressure. The self-locking cylinder will locked automatically. And the self-locking cylinder is unlocked when the oil comes inside from the“R” port.

HC self-locking cylinder advantage:

1.    No extra locking mechanisms

2.    Can bear more than ten tons of pressure

3.    No additional action

4.    Locking point clear

5.    Easy to install

6.    Well-sealed

7.    Well-designed

8.    Custom travel as needed

 HC hydraulic cylinder Co., Ltd has many years of  self-locking cylinder production experience. Using self-locking cylinder can greatly reduce the cost of tooling and processing.
