Abstract
The utility model relates to an injection machine, in particular to a reducing screw quick-replacer of an injection machine, which comprises a nozzle, a machine barrel, a carriage front board, a guide rod, a semi-ring, a sleeve pipe and a carriage back board; the utility model is mainly characterized in that a deformed key is arranged at the tail part of the screw and the sleeve pipe to form movable matching and connecting; that is to say, the tail part groove of the screw is engaged with a round lug boss in the deformed key; the radial surface lug boss of the deformed key is connected with the sleeve pipe. The diameters of the tail part of the screw and the deformed key connected with the sleeve pipe are mutually formed and are all connected in movable matching. The improvement of the structure solves the technical problem of conveniently and quickly replacing the screws with different diameters. The utility model has the characteristics of simple structure, convenient mounting, and easy operation, thus achieving the goals of saving time and labor to replace the screws.
Description
Technical field
The utility model relates to injection machine, is a kind of injection machine reducing screw rod quick change mechanism.
Background technology
In existing universal injection machine, the basic skills of changing screw rod has two kinds: one, remove nozzle, semi-ring, die sinking is extracted screw rod or install by opposite operation out from machine barrel is anterior to range then.Two, all hold-down screws of platform and corresponding protective plate and high-pressure oil pipe are penetrated in dismounting, then with the whole platform partial rotation of penetrating, remove nozzle, semi-ring, extract or press screw rod out opposite operation installation from the machine barrel front portion.Shaft coupling and screw rod tail size are subjected to the qualification of its structure, and excessive then versatility is relatively poor, and cause dismounting difficulty in the screw rod use; The too small transmission that then can't guarantee the driving torque of major diameter screw rod causes the inefficacy of undercapacity.So some screw rod, especially the tail dimension of minor diameter screw rod can be greater than the size of front end, two kinds of then traditional methods are all inapplicable but must remove machine barrel, penetrate all hold-down screws of platform and corresponding protective plate and high-pressure oil pipe, screw rod extracted out from the machine barrel rear portion after whole barrel is unloaded again or installed by opposite operation.This operation is with opposite from the anterior habituation operation of extracting out of machine barrel with screw rod, and operation is loaded down with trivial details, dismounting inconvenience.
Summary of the invention
For overcoming the deficiency of above-mentioned existence, the utility model purpose is to provide a kind of injection machine reducing screw rod quick change mechanism to this area, and it is loaded down with trivial details to make it solve operation, dismounting inconvenience, and cause the lower technical problem of operating efficiency.The purpose of this utility model realizes by the following technical solutions.
A kind of injection machine reducing screw rod quick change mechanism, this quick change mechanism comprise nozzle, machine barrel, screw rod, penetrate the platform header board, guide rod, semi-ring, shaft coupling, penetrate plate behind the platform, and its main points are that in screw rod tail and the shaft coupling special-shaped key being set is connected movingly; I.e. boss platform engagement in screw rod tail groove and special-shaped key, special-shaped key diametric plane boss connects with shaft coupling.
The diameter that described screw rod tail, special-shaped key connect with shaft coupling forms mutually, is movingly to connect.
By the improvement of said structure, solved the different-diameter screw rod and changed conveniently technical problem.Have characteristics simple in structure, easy for installation, easy operating, reach and change that screw rod saves time, the labour-saving purpose.
Description of drawings
Fig. 1 is the utility model general structure schematic diagram.
Fig. 2 is that part parts among Fig. 1 are to the left movement schematic diagram.
Fig. 3 is the screw rod schematic diagram, has made A-A among the figure and has analysed and observe.
Fig. 4 is A-A enlarged diagram of Fig. 3.
Fig. 5 is special-shaped key enlarged diagram.
The specific embodiment
Now in conjunction with above-mentioned accompanying drawing, embodiment is described below: the utility model by nozzle 1, machine barrel 2, screw rod 3, penetrate platform header board 4, guide rod 5, semi-ring 6, shaft coupling 7, penetrate plate 8 behind the platform, special-shaped key 9 is formed, in shaft coupling, be provided with special-shaped key, centre at machine barrel is provided with screw rod, connects nozzle in the end of machine barrel.The part that the screw rod tail diameter is difficult to end dismounting in the past more greatly will be divided into two parts, be the special-shaped key two parts that are provided with in screw rod tail and the shaft coupling, so corresponding the reducing of screw rod self afterbody just can realize extracting out or installing by opposite operation from barrel is anterior less than the screw front end size.In assembling process, guarantee to cooperate by tolerance.Just can take two kinds of traditional basic skills when changing screw rod:
One, remove nozzle, semi-ring, die sinking is extracted screw rod or install by opposite operation out from machine barrel is anterior to range then.
Two, all hold-down screws of platform and corresponding protective plate and high-pressure oil pipe are penetrated in dismounting, then with the whole platform partial rotation of penetrating, remove nozzle, semi-ring, extract or press screw rod out opposite operation installation from the machine barrel front portion.
Claims (2)
1, a kind of injection machine reducing screw rod quick change mechanism, this quick change mechanism comprises nozzle (1), machine barrel (2), screw rod (3), penetrates platform header board (4), guide rod (5), semi-ring (6), shaft coupling (7), penetrate plate (8) behind the platform, it is characterized in that in screw rod tail (301) and shaft coupling special-shaped key (9) being set is connected movingly; I.e. boss platform (901) engagement in screw rod tail groove (301) and special-shaped key, special-shaped key diametric plane boss (902) connects with shaft coupling.
2, injection machine reducing screw rod quick change as claimed in claim 1 mechanism is characterized in that the diameter that described screw rod tail, special-shaped key connect with shaft coupling forms mutually, is movingly to connect.
