Description
Technical field
The utility model relates to a kind of injection machine, and more particularly, it relates to the sliding and position limitation structure of the funcition table for injecting of injection machine.
Background technology
Injection machine has another name called injection (mo(u)lding) machine or injector, it utilizes mould for plastics to make the main former of the plastic products of various shape thermoplastic or thermosetting material, and injection machine is made up of injecting systems, Clamping System, Hydraulic Power Transmission System, electric control system, lubricating system, heating and cooling system, safety monitoring system etc. usually.
Include dynamic model seat and cover half seat in Clamping System wherein, dynamic model seat is installed the dynamic model part of mould, cover half seat is installed the cover half part of mould, completed and the matched moulds of cover half and parting action by the dynamic model part of dynamic model seat driven mold; Injecting systems comprises with injection rod and the funcition table for injecting that can move forward and backward with injection rod, the front end of injection rod is with the nozzle of the grog sprayed under melting state, nozzle is embedded the plug hole position of cover half part, but have difference due to the model of mould and size, the depth design of plug hole all can be different, nozzle due to injection rod needs to match with plug hole, thus cause funcition table for injecting to drive the forward travel distance of injection rod also can be different, if directly drive injection rod to advance by funcition table for injecting to make nozzle firmly clamp-on the plug hole of cover half, then can destroy nozzle.
As application number for 201320263646.X name to be called in the Chinese patent of " oil electric mixed dynamic injection machine " disclose, just refer to and move the advance of injection rod and the mode of retrogressing by oil cylinder direct tape splicing, this mode can cause the problem of the above-mentioned destruction nozzle mentioned.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of when funcition table for injecting promotes injection rod time, and nozzle can adapt to the structure of the depth of the plug hole of different mould.
For achieving the above object, the utility model provides following technical scheme: a kind of sliding and position limitation structure of funcition table for injecting, comprise frame, be located at the funcition table for injecting in frame, to be located on funcition table for injecting and platform can be injected and drive movable injection rod, described funcition table for injecting is driven by oil cylinder, working connection in described oil cylinder is provided with cam stop valve, described cam stop valve is located on the sidewall of funcition table for injecting, the adjustable positioning mechanism of the cam that can compress cam stop valve is provided with in frame, described adjustable positioning mechanism comprises holder and to be located on holder and the adjusting rod that can adjust along the direction of motion of funcition table for injecting, described cam stop valve can be formed to extrude with adjusting rod and cut off described cam stop valve in the drive process being injected platform.
By adopting technique scheme, oil cylinder can drive the movable of funcition table for injecting, thus drive the movable of the injection rod be arranged on funcition table for injecting, the driving force of oil cylinder is pressure oil, when cutting off working connection, just the power source of oil cylinder can be cut off, oil cylinder will stop the motion driving funcition table for injecting, according to the mould of different model, nozzle on injection rod all can be different from the plug hole cooperation position on the cover half of mould, the distance of funcition table for injecting needs movement is caused also to be not quite similar, can according to the mould of different model, on adjustable positioning mechanism, adjust funcition table for injecting in advance can the distance of movement, when funcition table for injecting is moved to the position of reserving in advance in the driving of oil cylinder, cam stop valve compresses making cam under the effect of adjusting rod and then working connection is blocked by cam stop valve, oil cylinder runs out of steam source, funcition table for injecting is mobile by stopping, play the effect of the move distance of locating injection platform, avoid nozzle by the problem of damaging by pressure.
Be optimized for further: described cam stop valve is arranged perpendicular to the direction of motion of funcition table for injecting, and the cam surface of described cam stop valve is arranged to the direction of adjusting rod, is provided with taper guide head in the end of described adjusting rod.
By adopting technique scheme, in occurring to extrude with adjusting rod under the drive of cam stop valve at funcition table for injecting, cam can present adjusting rod taper guide head effect under gradually move on the external cylindrical surface of adjusting rod, this mode is due to the guide effect of taper guide head, make the effect that is squeezed of cam stop valve better smooth and easy, and the moving displacement of the vertical direction of the cam of cam stop valve is exactly the radius of adjusting rod, ensure that the stopper rod moving displacement of cam stop valve, prevent from being displacement and having damaged.
Be optimized for further: described holder is provided with the perforated hole can worn and penetrate adjusting rod, being provided with in the sidewall of described perforated hole can the sidewall lock screw of degree of tightness adjusting rod.
By adopting technique scheme, the effect of degree of tightness adjusting rod can be played by sidewall lock screw, and the effect of the electrodeless adjusted position of adjusting rod can be realized, ensure that the mould of different model is the coupling that nozzle on injection rod can be safe and suitable when coordinating.
Be optimized for further: described holder offers the waist type groove of vertical direction, by the height of the adjustable holder of described waist type groove on vertical direction.
By adopting technique scheme, holder can be adjusted by waist type groove and be fixed on position on funcition table for injecting on vertical direction, one, when installation fixed station due to the position of its in the vertical direction can be adjusted, thus achieve the extrusion position that can adjust adjusting rod and cam stop valve, play convenient effect of installing; Its two, after practical a period of time, if the installation of fixed station and frame occurs loosening, thus adjusting rod cannot be made to be expressed to cam stop valve, again can adjust position by waist type groove, make adjusting rod can ensure to overwhelm cam stop valve.
The utility model advantage is compared with prior art: by the cam stop valve be arranged on funcition table for injecting and the adjustable positioning mechanism be arranged in frame, and adjustable positioning mechanism is by the electrodeless locate mode of holder in adjusting rod, achieve the electrodeless locate mode of position location when funcition table for injecting moves, make when injection machine being installed the mould of different model, funcition table for injecting can drive injection rod to move to suitable position, make nozzle obtain suitable mating with the plug hole on cover half, prevent nozzle by the problem of damaging by pressure.
