Description

Technical Field

[0001] The utility model relates to the field of die-casting die accessories, in particular to a novel oil cylinder. Background Art

[0002] Oil cylinder is also a hydraulic cylinder. Oil cylinder is often used on die-casting molds to control the opening and closing of die-casting molds. During the operation of the die-casting machine, hydraulic oil is pressed into the oil cylinder to move the piston of the oil cylinder, thereby driving the opening and closing of the die-casting mold.

[0003] Most oil cylinders use a travel switch to limit the stroke of their reciprocating motion. Therefore, a travel switch needs to be set on one side of the oil cylinder to meet the stroke requirement. The existing travel switch is connected to the piston rod through a connector. The existing connector is two semicircular arc plates combined and fixed by four bolts. The structure designed in this way is not easy to operate, and it is easy for the four bolts to be tightened differently, resulting in the bolts not being in place, thereby causing the connection to become loose, affecting the use effect of the oil cylinder.

[0004] Therefore, improvements must be made to address the above-mentioned defects. Utility Model Content
