(2) background technology
Existing injection machine, basically adopt two parallel guide rods guiding, with reference to Fig. 1, and the guide rod weight that in guiding, also will carry the own wt and the raw material of injection member, radial deformation takes place in guide rod under the effect of this gravity, make the precision of injection and storing reduce greatly; And be matched in clearance between guide rod and the fairlead, just determined that the precision of this structure is limited, and the friction between them is sliding friction, As time goes on, precision can be more and more lower.
And for example China Patent No. is: 02265526.3, the utility model name is called the improved utility model patent of The injection moulding machine preforms guidance system, a kind of guidance system of the power of can reducing friction is disclosed, comprise penetrate platform, the bearing of platform is penetrated in supporting, be provided with more than one linear rolling guide between platform, the bearing described penetrating, wherein, the slide block of described guideway is fixedlyed connected with the described platform bottom of penetrating, and the guide rail of described guideway is fixedlyed connected with described bearing.Advantage of the present utility model be to have changed of the prior art with plane planker or cylinder guide rod as guidance system, the mechanical friction power when making preformed diminishes, less energy consumption, thereby make the preformed back pressure be convenient to control, improved the precision of injection machine.
Because line slideway is not very desirable in stressed the best of vertical and guide pass at the stressed of other direction; The whole platform of penetrating all adopts line slideway in this patent, if the workman does not adjust to positive center when adjusting the center of nozzle, is in the non-perpendicular and power guide rod face to the stressed of line slideway so, can directly damage line slideway when situation is serious; There is bias state in the center of gravity of penetrating the platform header board not at the center, and the discontinuity of two guide rails that make has changed the stressed of guide rail, and be restricted the service life of equipment
(3) summary of the invention
Short for the service life of the injection mechanism that overcomes existing injection machine, be subjected to nozzle center to adjust improper infringement, the deficiency that action stability is poor, injection precision is limited of causing easily, the utility model provides a kind of long service life, be difficult for nozzle center adjusts and improperly causes infringement, injects quicker stablizing and the injection mechanism of the injection machine that precision is high.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of injection mechanism of injection machine, comprise and penetrate table mount, be positioned at and penetrate penetrating the platform header board, penetrate plate behind the platform on the table mount, described penetrating injection cylinder group, the whole oil cylinder group of moving are installed on the platform header board, oil motor, injecting piston rod are installed on the plate described after penetrating platform, described injecting piston rod connects with the injection cylinder group, the described bottom of penetrating the platform header board is provided with sleeve pipe, and described sleeve pipe is sleeved on the guide rod slidably, and described guide rod is installed in the place ahead of penetrating table mount; Describedly penetrate that the bottom of plate is provided with slide block behind the platform, described slide block is connected slidably with line slideway, and described line slideway is installed in the rear of penetrating table mount.
Further, described guide rod is two, is respectively equipped with two sleeve pipes in the described left and right sides of penetrating the platform header board.
Further again, described line slideway is two, described penetrate platform after the left and right sides of plate be respectively equipped with two slide blocks.
Technical conceive of the present utility model is: injection mechanism adopts guide rod to add the structure of line slideway, supporting part and the degree of being adjusted the center to equipment influential motion of penetrating the platform header board adopted the guide pillar guiding, owing to significantly reduced the length of guide rod, reduce gravity torque, reduced the gravity deformation of guide rod; And very high, the direct influence of motion frequency injection performance and storing performance penetrate platform after plate portion adopted the line slideway guiding.
Penetrating the platform header board uses the guide rod guiding not to be subject to the improper infringement to equipment of nozzle center's adjustment; And being directed at the center adjustment, line slideway can not damage line slideway at that time;
Used differential injection structure at injection cylinder, minimizing injection oil return reaches the back resistance when reducing injection when improving guiding, has improved the injection speed under equal pressure flow situation;
The beneficial effects of the utility model mainly show: long service life, be difficult for nozzle center adjust improperly cause infringement, injection is quicker stablizes and the precision height.
