Description
Technical field
The utility model relates to large size plastic jetting-moulding device single cylinder injecting systems technical fields, more particularly to a kind of large-scale two trigger
Single cylinder injection molding sealing and supporting structure.
Background technique
Due to large size plastic jetting-moulding device single cylinder injection system, to identical injection pressure, glue injection oil cylinder diameter is bigger, and does revolve simultaneously
Turn, straight reciprocating motion, sealing structure requirement is higher, the phenomenon that hydraulic fluid leak easily occurs, injection piston rod is also easier to damage
It is bad.The structure utilizes high-intensitive aldubra material characteristic effective protection injection piston using copper sheathing bearing and dual oil leak protection
The frictionally damage in rotation and linear reciprocation peculair motion, raising injection piston rod service life do not reduce maintenance on bar surface
Cost.Meanwhile the part oil liquid of leakage effectively being avoided with oil return hose connection oil return box after oil-filtering apparatus filter cleaning
With the large-scale single-cylinder injection molding machine injection piston rod oil leak of solution, environmental pollution and fuel tank hydraulic oil is caused to reduce problem.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of large-scale two triggers single cylinder injection molding sealing and bearings
There is structure the protection for improving injection piston rod, the service life for increasing structure, reduction maintenance cost to avoid the occurrence of oil leak
Situation guarantees that working environment is not contaminated, avoids the features such as fuel tank hydraulic oil reduction.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of large-scale two triggers single cylinder injection molding
Sealing and supporting structure, including injection piston rod, platform part and copper sheathing are penetrated, the injection piston rod, which is mounted on, penetrates platform part
Interior, the extension end end of the injection piston rod by being socketed with rotation outside framework oil seal and copper sheathing, the rotation from left to right
Outside framework oil seal and copper sheathing, which are embedded in, to be penetrated in platform part, and is isolated by penetrating platform part protrusion inner ring, the copper sheathing inner ring
Several wear rings have been mounted side by side in insertion, and wear ring is socketed on injection piston rod outer ring, the injection piston rod outer ring
Insertion is equipped with O-ring seal, and rotation pressure is equipped at the copper sheathing and the inner ring for penetrating the one end platform part protrusion inner ring Xiang Ding
Power oil sealing, the rotational pressure oil sealing are bonded with injection piston rod outer ring and mutually push up with platform part protrusion inner ring is penetrated.
Described rotation outside framework oil seal one end is mutually pushed up with platform part protrusion inner ring is penetrated, and the other end and being mounted on is penetrated in platform part
Retaining ring on circle mutually pushes up.
It is connected to by unloading oilhole with oil unloading trough between the rotation outside framework oil seal and rotational pressure oil sealing.
The utility model has the advantages that the utility model relates to a kind of large-scale two triggers single cylinder injection molding sealings and supporting structure to use copper sheathing
Bearing and dual oil leak protection, and increase drain pan, oil leak hole, it can effectively avoid and solve injection piston rod Leakage, it is high
Rotational pressure oil sealing is fixed by the use of intensity aldubra copper sheathing, is reached rotational pressure oil sealing installation fixed effect, is revolved
It is not performed relative motion when turning with straight reciprocating motion, injection piston rod protection is reinforced, is improved service life, reduce maintenance
Cost.
