Abstract
The utility model discloses a cylinder with adjustable needle, including needle, piston and cylinder body, the needle is installed on the piston, the piston can be installed with reciprocating the cylinder is originally internal, it is adjustable about the position of needle on the piston. After adopting such structure, can not change whole injecting glue cylinder during the hot runner injecting glue because the mould plate thickness changes or change the template, only need with the height of needle adjust a little can, saved the cost, improved work efficiency.
Description
Technical field
This utility model hot flow path injection molding art, particularly relates to a kind of needle adjustable cylinder.
Background technology
In hot flow path injecting glue prior art, it is typically all and is completed by needle-valve, the gum-injecting port of needle-valve and template is that the sharp-tongued injecting glue import tightly withstanding template by needle-valve seals, the needle of needle-valve is fixedly mounted on the piston of cylinder, withstands the sealing of template gum-injecting port by the adjustment needle that moves up and down of cylinder piston.In real work, the thickness of template, cylinder piston range be all pre-set, if all gone well, that is also out of question, but is commonly present deviation during the thickness of template, the stroke causing cylinder piston has been used to the greatest extent, all can not make the sharp-tongued gum-injecting port sealing up itself and template of needle, it is therefore necessary to change whole needle-valve or change template, cause the very big increase of cost, waste many time, have impact on work efficiency.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is in that to provide a kind of convenient cylinder of needle up-down adjustment.
For achieving the above object, this utility model adopts the following technical scheme that a kind of needle adjustable cylinder, and including needle, piston, cylinder body, described needle is arranged on piston, described piston can move up and down in described cylinder body, and described needle position on piston is adjustable up and down.
Further, described needle axis overlaps with piston axis.
Further, there is a flange on the top of described needle；The screwed hole of a up/down perforation is had at the center of described piston, described needle is fixed in described screwed hole by a spiral shell button, this spiral shell button is cylindrical, its upper semisection excircle has the external screw thread mated with described screwed hole, lower semisection excircle diameter is slightly smaller than the minimum diameter of described screwed hole, and in the side, middle part of lower semisection radially and exceed described spiral shell and smash axle alignment opposite side and cut out the axial notch of one fixed width, the thickness matching of this width and described flange, and ensure that described flange can move left and right in described axial notch；On the lower wall of described axial notch, middle part be provided with radial groove, this radial groove is also above the central axis of described spiral shell button, and described needle can move left and right in described radial groove.
Further, adding a locking screw button on described spiral shell button, this locking screw button buckles with described spiral shell and sticks together, and its excircle has external screw thread to mate with described screwed hole.It is provided with the hexagonal groove caved in the center of described spiral shell button and the top end face of locking screw button.
Compared to existing technology, the beneficial effects of the utility model are in that: needle upper-lower position on piston is adjustable, when template thickness is beyond the situation of legitimate skew, solve the problem not needing to change template or whole needle-valve, reduce cost, facilitate work, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of spiral shell button of the present utility model；
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
In hot flow path injecting glue technical field, during injecting glue, being meet the compression air of pressure requirements by injecting to the epicoele of piston 2, piston 2 is descending under stress, until the sharp-tongued gum-injecting port tightly withstanding template of needle, and seals up and does not leak glue, can carry out.After injecting glue completes, if in the cavity of resorption of piston 2 injecting compressed air, by piston jack-up, then remove whole needle-valve, even if whole process completes.
In this utility model, as shown in Figure 1, 2, a kind of needle adjustable cylinder, including needle 1, piston 2, cylinder body 3, needle 1 is installed on the piston 2, and piston 2 can move up and down in cylinder body 3, and needle 1 is hung on piston 2 axis by the flange 4 on its top.The center of piston 2 is provided with the screwed hole 5 of a up/down perforation, is provided with spiral shell button 6 and the locking screw button 10 of threaded engagement with it in screwed hole 5.The structure of spiral shell button 6 is, overall in cylinder, excircle has external screw thread, upper semisection coordinates with the screwed hole 5 of piston 2, the external diameter of lower semisection is more slightly smaller than the minimum diameter of the screwed hole 5 of piston 2, and in the middle part of lower semisection radially and exceed spiral shell button 6 central axis and cut out the axial notch 7 of one fixed width to opposite side, the width of this axial notch 7 is suitable with the thickness of the flange 4 of needle 1, needle 1 is just suspended in this axial notch 7, and ensures that the flange 4 of needle 1 can move left and right in axial notch 7.Axial notch 7 is alternatively more than half circular arc, as long as the flange 4 of needle 1 can hang up, axially consolidates, transversely can freely move all right.It addition, on the lower wall 8 of axial notch 7, middle part be provided with radial groove 9, this radial groove 9 is also above the central axis of spiral shell button 6, and needle 1 can move left and right in radial groove 9.
The main position pinning spiral shell button 6 of effect of locking screw button 10, does not allow it have any sliding up and down, otherwise the sharp-tongued gum-injecting port that can not seal template of needle 1 and cause leakage glue.
And for mounting or dismounting locking screw button 10 and spiral shell button 6 easily, offer hexagonal groove 11 respectively on both tops, the size of this hexagonal groove 11 should in the same size with standard hex spanner, different sizes can be chosen according to actual needs.
Screwed hole 5 on piston 2 can be arranged to the length being of uniform thickness with piston 2, it is also possible to is arranged to the shape such as Fig. 1, and the thickness that length is longer than piston 2 is a lot, and this can arrange according to actual needs and choose.Spiral shell button 6 can be fixed on arbitrary At The Height of screwed hole 5 by locking screw button 10, and this depends entirely on the actual (real) thickness needs of template, adjusts to suitable position.When needle being suspended on spiral shell button 6, actually it is secured on piston 2.
The thickness of the flange 4 of needle 1 must be few with the stand out of axial notch 7, and ensures that needle-valve can be detachable, and otherwise needle rocks at axial notch 7, can affect injecting glue effect and work efficiency.On the contrary, the width of radial groove 9 may be slightly larger than the diameter of needle 1, then do not have a great impact.
Preferably, the axis of the axis of needle 1 and piston 2 is on same straight line, and this is by the operation of more convenient reality.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims.
