Background technology
Injection machine is a kind of production equipment conventional in modern industry, it needs thimble to be come from mold ejection by product after processing product, due to the volume of some product and quality larger, so often need two oil cylinders to promote the movement of thimble push plate, two thimble oil cylinders are by same P chamber oil-feed, when ejector retainner plate is initial, because the reasons such as mismachining tolerance and hydraulic oil oil-feed speed can cause ejector retainner plate to move back terminal hour discontinuity, so ejector retainner plate is likely caused to rupture for a long time, in the process ejected fast in addition and return, piston in oil cylinder cover plate that is easy and oil cylinder collides, cause Remedy for Piston Damage.
Summary of the invention
What technical problem to be solved in the utility model was to provide the two ejection cylinder of a kind of injection machine moves back position-limit mechanism, ejects and return all limited location mechanisms to piston, prevents ejector retainner plate from moving back terminal hour discontinuity, also prevents piston collisions and damage.
The utility model solves the technical scheme that its technical problem adopts: what provide the two ejection cylinder of a kind of injection machine moves back position-limit mechanism, comprise ejector retainner plate, oil cylinder and base plate, described ejector retainner plate is arranged in the top of base plate, described oil cylinder has two lower ends being arranged side by side in base plate, this oil cylinder comprises cylinder body, slide the piston be arranged in cylinder body and the piston rod be connected with piston upper end, described cylinder body be separately installed with protecgulum and bonnet up and down, described protecgulum is connected with base plate, upper end and the ejector retainner plate of described piston rod are fixedly linked, upper cover of piston rod between described ejector retainner plate and protecgulum is connected to thimble lid sheath, the two ends symmetry of described ejector retainner plate is vertically inserted with limited post, the top of this limited post protrudes upward, middle part is threaded with ejector retainner plate, lower end is socketed with locking nut.
Supplement as to the one of technical scheme described in the utility model, the pull bar by being arranged in cylinder body both sides between described protecgulum and bonnet is connected.
Supplement as to the one of technical scheme described in the utility model, described thimble lid sheath is cylindrical, and be embedded in base plate, its lower surface and protecgulum withstand, and upper surface is exposed in base plate upper surface.
Supplement as to the one of technical scheme described in the utility model, the upper end of described locking nut is furnished with bullet pad, and bullet pad compresses by the lower surface of locking nut and ejector retainner plate.
Hydraulic oil enters into cylinder body from bonnet, promotion piston rod and piston move up, piston rod promotes ejector retainner plate and moves up, product on mould ejects by the thimble on ejector retainner plate, time ejector retainner plate moves to the position near lower bolster, upper end and the lower bolster of limited post withstand, and prevent the piston in oil cylinder and protecgulum from colliding.
When hydraulic oil releases, piston rod and piston move down, and withstand until the lower surface of ejector retainner plate contacts with the upper surface of thimble lid sheath, prevent piston and bonnet from colliding.
When needing the position regulating limited post, unscrewed by locking nut, then rotary spacing post regulates the height of limited post, has regulated rear locking nut screwing to pin.
beneficial effect
What the utility model related to the two ejection cylinder of a kind of injection machine moves back position-limit mechanism, ejects and return all limited location mechanisms to piston, prevents ejector retainner plate from moving back terminal hour discontinuity, prevents ejector retainner plate from rupturing, also prevent piston collisions and damage.
