Abstract
The utility model relates to a copper bush structure for mould-moving cylinders. The design of a mould-moving cylinder structure changes the seal ring of a front cover of a mould-moving cylinder into the copper bush structure, and arranges a lubrication hole for lubrication. When an injection molding machine system is started, a piston rod assembly is pushed by oil getting into and out of the front cover and a back cover of the mould-moving cylinder to reciprocate, and can reciprocate at high speed under the supporting and guiding function of a copper bush.
Description
Affiliated technical field
The utility model relates to a kind of mould shifting oil cylinder copper sheathing structure of injection moulding machine.
Background technique
Injection machine forming machine thimble oil cylinder, Mode-locking oil cylinders etc. are generally all short strokes, the inner parts that play guiding and seal action of its oil cylinder are nearly all resilient rubber products.And the mould shifting oil cylinder that in two-plate injection machine, the folding mould is used due to route problem, is all the mould shifting oil cylinder that adopts long stroke; So continue to adopt with mould shifting oil cylinder the structure that the conventional oil cylinder interior all adopts the rubber product Sealing for two-plate injection machine, the high frequent athletic meeting of injection machine makes the piston rod assembly of long stroke produce crooked existing picture; The Sealing of piston rod assembly and rubber product produces frequent friction, the Sealing that can wear and tear, thus the problems such as overhang and leakage of oil appear; These all can not satisfy the stability of injection machine.
Summary of the invention
Technical problem to be solved in the utility model: a kind of mould shifting oil cylinder copper sheathing structure.The design of this mould shifting oil cylinder structure is that the seal ring with mould shifting oil cylinder protecgulum place makes to use the copper sheathing structure into, and joins lubrication hole and regularly be lubricated effect.When injection machine system started, the oily pushing piston bar assembly of mould shifting oil cylinder front and rear covers turnover moved reciprocatingly, and piston rod assembly can be done to-and-fro motion frequently at a high speed under the effect of the support guide of copper sheathing.
The utility model solves the technological scheme that its technical problem adopts: a kind of mould shifting oil cylinder adopts the copper sheathing structure.It comprises piston rod assembly, the oil cylinder protecgulum, and cylinder body, the oil cylinder bonnet, copper sheathing is covered with dust, oil sealing, wear ring, oil sealing.The oil cylinder protecgulum is arranged on the cylinder body front end; The oil cylinder bonnet is arranged on the cylinder body rear end; It is inner that piston rod assembly is installed cylinder body; Copper sheathing is arranged on the oil cylinder protecgulum foremost and joins lubrication hole and carry out the timed lubrication effect; Be covered with dust, oil sealing, wear ring, oil sealing install in the oil cylinder protecgulum after copper sheathing successively.
When injection machine system started, oil cylinder protecgulum and the oily pushing piston bar assembly of oil cylinder bonnet hydraulic fluid port turnover moved reciprocatingly, and piston rod assembly and copper sheathing produce frequent friction; Copper sheathing plays the support guide effect, and lubricant oil regularly can make copper sheathing form oil film, plays a protective role; Adopt the copper sheathing structure not only to solve overhang and the Leakage that can occur with the rubber product seal configuration; And improved the rigidity of piston rod assembly, also reached the purpose of oil cylinder high-precision requirement.
The beneficial effects of the utility model: the accessory wear rate is low, can use for a long time Maintenance free, the characteristics of long service life.Life-span and the stability of mould shifting oil cylinder have been improved, the generation that has solved overhang and Leakage.Having improved the rigidity of piston rod assembly, also reached the purpose of oil cylinder high-precision requirement. these are the large stability that promotes injection machine all.
