Description

Vertical disc multicolor plastic sole injector

Technical field

The utility model belongs to injection (mo(u)lding) machine, is specifically related to a kind of multicolor plastic sole injector.

Background technology

The utility model relates to a vertical disc multicolor plastic sole injector.Existing disk plastic sole injector double-colored or three looks mostly are horizontal heavy duty machine tools, concentrate the talk of its occupation of land and just need more than 30 square metre, weight 10-20 ton is heavy, that have even surpass 20 tons of weights, and die cylinder mostly is mounted in the disk below, has the locked mode hole on the disk, all there is decking in each locked mode hole, during matched moulds, the oil cylinder piston bar of matched moulds will pass the locked mode hole on the disk, the decking that mould is housed is pushed up on the injection head inject.During die sinking, piston rod must fall back on below the disk, disk just can forward next pair mould to and carry out subsequent processing, make the matched moulds cycle long, can not shorten activity time, limited the output of depanning, the plastic sole injector of stupid but also slow heavily not only so not only double-colored or three look, but the main production lathe of double-colored at present or three look plastic sole.

The utility model content

The purpose of this utility model provides that a kind of cost is low, power consumptive province, occupation of land multicolor plastic sole injector little, with short production cycle.

The technical scheme that realizes the utility model purpose is: a kind of plastic sole injector of vertical disc polychrome, go up at same support (1), can inject a kind of plastics of color with same disk, Vertical Rack of Vertical Rack (support is shown in figure (1)) that 1-3 platform varying number can be installed, many Vertical Racks just can inject the plastic sole of multiple color.With original die cylinder in the existing design under the disk above disk, in-oil cylinder piston rod does not just need to pass locked mode hole on the disk when matched moulds like this.As long as the speed of matched moulds just can be accelerated widely in the plane on adjusting injection head lower plane and the mould within one centimetre.Also save 20 polylith deckings simultaneously.Be equipped with 20 on the disk and overpay mould, every pair of mould vertical die bottom plate place under injection port is contained on the disk with a bolt.As: needing to install 24 pairs of moulds on the disk, as long as on this disk, is radius with the center of circle of disk to the centre distance of injection port, does circle 24 parts of borings of five equilibrium afterwards just with the center of circle of disk.Every Vertical Rack is by five overlapping installations of frame plate.For reaching pressure balance, the oil cylinder of matched moulds and injection all adopts two oil cylinder work; Use the oil motor preformed.Die cylinder and injection cylinder all are installed on the upper frame plate (7), and the piston rod of two oil cylinders (8) of matched moulds is installed on the matched moulds plate (10) with nut, and barrel (6), two pressure columns (5) also fixedly are housed on the matched moulds plate (10).After barrel (6) and pressure column (5) pass upper frame plate (7), refill top die plate (4), constitute clamping pressure mechanism.The external diameter of matched moulds plate (10) and injection cylinder (9) is processed into to be slidingly matched and plays the guide pillar effect.Like this as long as the piston up-down of die cylinder (8) all and then moves up and down matched moulds plate (10), barrel (6), two pressure column (5) and pressuring template (4) simultaneously.The piston rod of double injection oil cylinder (9) is installed on the injection plate (12) with nut, and oil motor (13) is equipped with the injection screw of band preformed also with fixing on the injection plate (12) on oil motor (13) core bar.A pair of post (16) is separately fixed at up and down on Weight plate (14) and the matched moulds plate (10), plays guide effect up and down with injection plate (12).Plastics enter barrel when the oil motor preformed by the charging aperture (11) of barrel (6) upper end, and the lower end of barrel is formed the pass and expected mechanism by sealing screw (19) and plug (20).Seal screw (19) and be contained in the barrel lower end with screw thread, 18 one-tenth of plug (20) and the hole φ that seals screw (19) are movingly, seal the hole φ 18 thick 20mm of being of screw, and plug φ 18 cooperates director 30mm, plug (20) is put into and is sealed screw (19) hole, big step up, when matched moulds is injected, during plug contact mould plane, sliding on the plug, 4 hole φ 5 are arranged in the cooperation place, mould is injected in charging, when die sinking, slides into the step plane under the plug making under the gravity effect, 4 hole φ 5 are shut in the cooperation place, at this moment in the barrel the plastics of preformed just closed in barrel.The preformed of oil motor (13) is plastics of being controlled each mold cavity by programmable controller (PLC).Injection cylinder (9) is only served as the effect of the plastics that preformed is good in the barrel being injected mold cavity in the utility model.Returning of injection cylinder piston is by following 3 points: 1, by weight (15) that pulley is housed on the Weight plate (14) and oil motor (13), the weight of injection plate things such as (12) is made relative equilibrium; 2, the spool of reversal valve is selected " y " type, becomes the release path after the outage; 3, under above two conditions, it is that power just can return at leisure that the oil motor preformed is arranged.That is to say: the beginning that the beginning of preformed returns for piston, preformed end up being piston and return and put in place.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model technology contents is further described.

(embodiment 1)

See Fig. 1,1-3 platform Vertical Rack can be housed on the support (1), and [figure (1) is 3 look supports, mainly be that dress pressure oil is main body in the case], be equipped with 20 on the disk and overpay mould, by 4-6 only the stand-off (18) of below band spring parallels that disk (3) holder is disembarked on the frame base plate (2) exceed 2-4mm, when disk rotates not by frictional impact.Be contained on the disk with a bolt perpendicular to the die bottom plate place under the injection port of every pair of mould.When disk (3) forwards injection port position on the mould under the drive of decelerator (17), put in place under the effect of location near switch, make motor (17) brake, be parked in the injection head below, aim at injection port, die cylinder action piston presses down, when touching mould, disk is by stand-off (18) also and then being pressed downward at the effect float downward of spring, up to and framework soleplate (2) on parallels compress, the contact pressure list index puts in place, die cylinder time-delay pressurize, injection cylinder (9) work, piston presses down, injection plate (12) is gone up be with the preformed screw rod also to press down simultaneously on the fixing oil motor core bar, the plastics of having moulded are injected mold cavity, near switch connection injection cylinder (9) release, the preformed of oil motor (13) beginning at the same time is after preformed arrives the position of setting when putting in place, preformed stops, after die cylinder (8) delay arrival time, die cylinder (8) starts upwards die sinking, and barrel lower end injection port has plug to close material, plastics just can not flow automatically, disk is during along with die sinking, and the parallels that leaves on the framework soleplate (2) under the spring action of stand-off (18) below exceeds 2-4mm, and die sinking stops when running into travel switch when die sinking is risen.At this moment disk starts, rotates to next mould next fingerprint tool die cavity mold filling that circulates like this by decelerator (17).The utility model is on same support, with a disk, the vertical injection frame of 1-3 platform can be installed, adopt programmable controller (PLC) to control each procedure, with block switch control start platform number, have again and can select manual and automatic working procedure, each Vertical Rack all has an independent cover oil gear etc.Above is reasonable in design, and compact conformation is easy to use, and feed consumption power consumptive province, output height, cost be low, to take up an area of be the desirable type of producing multiple colored plastic sole or foamed plastic sole for a short time.
