Abstract
The utility model discloses a positioner's needle is prevented changeing by utensil, including installing at inside needle and the flow distribution plate of hot mouth, wherein the drive needle is connected with the cylinder to the needle, sets up an one -tenth body structure behind the valve needle sleeve on the needle, flow distribution plate and cylinder between set up the briquetting, valve needle sleeve is last to have a hollow rotation -proof structure, valve needle sleeve utilizes the briquetting installation fixed after the rotation -proof structure suit is on valve needle sleeve, the needle is connected with the cylinder. This rotation -proof structure mainly includes a square structure of a hollow and a hollow semicircular structure who extends along square structure, above -mentioned square structure and semicircular structure and needle surface matching. Needle bottom surface match with rotation -proof structure. Adopt the positioner's needle is prevented changeing by utensil after the above -mentioned scheme, it can be fixed a position fast, does not skid, and processing is simple, and calibration is compared to the location. Simple process is with low costs to actual technical problem can be solved, the convenience is brought for the industry.
Description
Technical field
This utility model is related to hot flow path field, more particularly, to for the needle in hot flow path field, valve more particularly, to
Pin anti-rotation positioning device.
Background technology
TOP-TIP shortens product molding cycle, saves plastic raw materialss, reduces expense product due to having, and improves product matter
Amount, increasingly applies wide, and central hot mouth technology is also developed accordingly, but the needle structure design in hot mouth also has
Wait to improve, such as needle is easily skidded with when being coordinated with inclined-plane, and particularly on curved surface, needle can not do positioning and can lead to product
Not conforming to rate increases,
Have and reflect and this, the present inventor, through concentrating on studies, invents a kind of needle anti-rotation positioning device above-mentioned to solving
Problem.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of quick positioning, processes simple,
The calibrated needle anti-rotation positioning device of contrast locating and realization quickly position non-slip novel valve needle.
The technical solution of the utility model is as follows:
A kind of needle of tool anti-rotation positioning device, including the needle being arranged within hot mouth and flow distribution plate, wherein needle
It is connected drive needle with cylinder, into a single integrated structure after setting valve needle cover on needle；It is characterized in that: described flow distribution plate and cylinder
Between arrange briquetting, valve needle cover has a hollow anti-rotation structure, valve needle cover be sleeved on valve needle cover through anti-rotation structure after profit
Installed with briquetting and fix, needle is connected with cylinder.
This anti-rotation structure mainly includes a hollow square structure and the hollow semicircle extending along square structure
Structure, above-mentioned square structure and semi-circular structure are mated with valve needle surface.
Described needle bottom outer surface is mated with anti-rotation structure.
Using the needle of the tool anti-rotation positioning device after such scheme, it can quickly position, non-slip, and processing is simple, fixed
Bit comparison is accurate.Process is simple low cost, and the technical problem of reality can be solved, bring convenience to industry.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is anti-rotation device schematic diagram in Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail:
A kind of needle of tool anti-rotation positioning device as depicted in figs. 1 and 2, including the needle 5 being arranged within hot mouth 6 with
And flow distribution plate 1, hot mouth 6 setting hot mouth sheath 7；Valve needle cover 3 is arranged on needle 5；Wherein needle 5 is connected drive needle 5 with cylinder 4
Work, arranges briquetting 2 between flow distribution plate 1 and cylinder 5, and valve needle cover 3 has a hollow anti-rotation structure 8, and valve needle cover 3 is through anti-rotation
After structure 8 is sleeved on needle 5, needle 5 is connected with cylinder 4.Wherein anti-rotation structure 8 mainly include a hollow square structure with
And the hollow semi-circular structure along square structure extension, above-mentioned valve needle cover 3 square structure and semi-circular structure and needle 5 bottom
Surface matching realize be accurately positioned.
Using the needle of the tool anti-rotation positioning device after such scheme, it can quickly position, non-slip, and processing is simple, fixed
Bit comparison is accurate.Process is simple low cost, and the technical problem of reality can be solved, bring convenience to industry.
