Description
Technical field
The component structural on a kind of injection machine is the utility model is related to, more particularly, to a kind of rack being connected with bearing
Bar copper department.
Background technology
Injection machine also known as injection (mo(u)lding) machine or injector.It is that thermoplastic or thermosetting material are utilized into plastic forming dies
The main former of variously-shaped plastic products is made in tool.Injection machine according to injection device and clamping apparatus arrangement side
Formula, vertical, horizontal and vertical sleeping combined type can be divided into.
Injection machine forming machine thimble oil cylinder, Mode-locking oil cylinder etc. are all generally short strokes, risen inside its oil cylinder be oriented to and
The part of sealing function is nearly all flexible rubber.And in two-plate injection machine open mold mould shifting oil cylinder, by
All it is the mould shifting oil cylinder using long stroke in route problem；So continue to adopt for two-plate injection machine mould shifting oil cylinder general
All using the structure of rubber seal inside logical oil cylinder, the frequent athletic meeting of height of injection machine makes the piston of long stroke
Bar assembly produces the existing picture of bending.The seal of piston rod assembly and rubber, which produces, frequently to rub, meeting abradable seal member, so as to
There is the problems such as cantilever beam and oil leak；These can not all meet the stability of injection machine.
Rack bar copper department is mainly contacted, it is necessary to good supporting role be played, due to it by surface with moving component
Surface frequently contacts with moving component, guide rail or workpiece table top, easily produces abrasion, it is therefore desirable in rack bar copper department body
Increase lubricant grease on surface, in order to further increase the amount of storage of lubricant grease, it is necessary to set oil groove in rack bar copper department,
And the tank structure setting in existing rack bar copper department is unreasonable, lubricant effect is poor, influences using effect.Therefore, it is necessary to
Existing rack bar copper department structure is optimized.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of rack bar copper department being connected with bearing, it is ensured that lubrication
Grease can be good at being diffused into rack bar copper department body surface, ensure that lubricating oil fat can be contacted fully with corresponding component, effectively
Prevent way rub.
Technical scheme is used by the utility model solves above-mentioned technical problem：The rack bar copper department being connected with bearing,
Including copper department body, described copper department body is the block structure of strip and is arcuately curved, described copper department body surface
Multiple mounting holes are evenly distributed with, copper department body surface is additionally provided with a groove, and the bending of described groove waviness includes
Multiple crest sections for linking together and multiple trough sections, described mounting hole site in the top of trough section, described groove
Middle part is provided with oilhole.
The further preferred scheme of the utility model：Described copper department body surface is evenly distributed with four mounting holes.
The further preferred scheme of the utility model：Described groove includes Duan Yusan crest section of four troughs, one
The both ends of crest section are all connected with trough section.
The further preferred scheme of the utility model：The middle part of described groove is crest section, and described oilhole is arranged on
The peak of described crest section.
The further preferred scheme of the utility model：The diameter of described trough section is less than the diameter of crest section.
The further preferred scheme of the utility model：Described crest section is set close to the madial wall of copper department body, described
Trough section close to copper department body lateral wall set.
The further preferred scheme of the utility model：The upper surface bore of described mounting hole is more than lower surface bore, and
The middle part of mounting hole is that the conical surface connects upper surface and lower surface.
Compared with prior art, the utility model has the advantage of the block structure and camber that copper department body is strip
Bending, copper department body surface are evenly distributed with multiple mounting holes.The structure of copper department body is so designed that, can adapt to its mounting ring
Border, working environment.Copper department body surface is additionally provided with a groove, and the bending of groove waviness is multiple including linking together
Crest section and multiple trough sections, mounting hole site are provided with oilhole in the middle part of the top of trough section, groove.Lubricant grease can lead to
Oil-through hole reaches groove, and can be good at being diffused into rack bar copper department body surface by groove, and guarantee lubricating oil fat can fill
Divide and contacted with corresponding component, effectively prevent way rub.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view of mounting hole.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
