Abstract
The utility model discloses a compact type hot runner system with two valve needles. The compact type hot runner system with the two valve needles comprises a hot nozzle main body, the valve needles, valve needle fixing seats, a cylinder sleeve and a cylinder piston; two hot runners through which the two valve needles respectively pass are arranged in the hot nozzle main body, and each of the hot runners is provided with a loudspeaker-shaped bottom end; a hot nozzle embedding sleeve is mounted at the upper end of each of the hot runners; the valve needles pass through the hot nozzle embedding sleeves; the valve needle fixing seats are of T-shaped structure, and two mounting holes are formed in the valve needle fixing seats; the upper ends of the two valve needles are mounted onto the valve needle fixing seats through the two mounting holes; the valve needle fixing seats are fixedly connected with the cylinder piston through screws; the cylinder piston is movably mounted inside the cylinder sleeve. According to the design of the compact type hot runner system with the two valve needles, the two valve needles has small center distances, so that the structure is compact, and the special requirements of the design of the hot runner of an injection mould are also met; in addition, the valve needles can be fixed well together with the valve needle fixing seats, so that the stability of the valve needles in work is ensured.
Description
Technical field
The utility model relates to a kind of TOP-TIP, particularly the two hot runner system with valve needles of a kind of compact.
Background technology
In current various TOP-TIPs, needle valve type hot runner system is saved material, and the plastic surface aesthetic of production, internal soundness is tight, intensity is high.On needle valve type hot runner system, be provided with needle, needle in the vertical direction can move upward and open or move downward closed hot mouth.Current needle valve type hot runner system, hot mouth main body is generally only provided with a needle, even or have two needles, the centre-to-centre spacing of these two needles is larger, cannot accomplish cramped construction, cannot meet the injection mold hot runner design of the goods that have specific (special) requirements.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of compact two hot runner system with valve needles, the hot mouth main body of the two hot runner system with valve needles of this compact is provided with two needles, and the centre-to-centre spacing of these two needles is less, has met and had the design of the injection mold hot runner of specific (special) requirements.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: the two hot runner system with valve needles of a kind of compact, comprise hot mouth main body, needle, needle holder, cylinder jacket and cylinder piston, in described hot mouth main body, be provided with two hot flow paths, in every hot flow path, be equipped with a needle, the bottom flare of every hot flow path, a hot mouth edge cover is equipped with in the upper end of every hot flow path, described needle is through described hot mouth edge cover, described needle holder is T shape structure, needle holder is provided with two installing holes, the upper end of described two needles is installed on described needle holder by these two installing holes, described needle holder is fixedly connected with cylinder piston by screw, described cylinder piston is movably installed in cylinder jacket.
Further, the centre-to-centre spacing between described two needles is 10mm.
Further, described hot mouth edge cover is shaped as T shape.
Further, described two hot flow paths Parallel Symmetric setting in hot mouth main body.
The beneficial effects of the utility model are: in the hot mouth main body in the utility model, be provided with two hot flow paths, be provided with a needle, and the centre-to-centre spacing of two needles be very little in every hot flow path.Utilize the design of the two hot runner system with valve needles of the utility model compact, can accomplish that centre-to-centre spacing is 10mm, realized compact structure, met and had the design of the injection mold hot runner of specific (special) requirements.In addition, needle holder can well be fixed needle, guarantees the stability of needle work.
Accompanying drawing explanation
Fig. 1 is the structural representation of the two hot runner system with valve needles of the utility model compact.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figure 1, the two hot runner system with valve needles of a kind of compact, comprise hot mouth main body 1, needle 2, needle holder 3, cylinder jacket 4 and cylinder piston 5, in described hot mouth main body 1, be provided with two hot flow paths 6, in every hot flow path 6, be equipped with a needle 2, the bottom flare of every hot flow path 6, corresponding to the also flare of hot mouth main body 1 bottom of every hot flow path 6 bottoms, a hot mouth edge cover 7 is equipped with in the upper end of every hot flow path 6, described needle 2 is through described hot mouth edge cover 7, described needle holder 3 is T shape structure, needle holder 3 is provided with two installing holes, the upper end of described two needles 2 is installed on described needle holder 3 by these two installing holes, described needle holder 3 is fixedly connected with cylinder piston 5 by screw, described cylinder piston 5 is movably installed in cylinder jacket 4.
Furtherly, the centre-to-centre spacing of described two needles 2 is 10mm.Described hot mouth edge cover 7 be shaped as T shape.Described two hot flow paths 6 are in the interior Parallel Symmetric setting of hot mouth main body 1.
During work, colloidal sol enters two hot flow paths 6 of hot mouth main body 1, and the cast gate of realizing two closer distance enters glue.While closing cast gate, under air pressure thrust, cylinder piston 5 drives two needles 2 that are arranged on needle holder 3 to move downward, and needle 2 ends seal cast gate.Hot mouth edge cover 7 can play guide effect to needle 2, and can prevent holiday.Needle holder 3 can well be fixed needle 2, guarantees the stability that needle 2 is worked.In hot mouth main body 1, be provided with two hot flow paths 6, in every hot flow path 6, be provided with a needle 2, and the centre-to-centre spacing of two needles 2 be very little.Utilize the design of the two hot runner system with valve needles of the utility model compact, can accomplish that the centre-to-centre spacing of two needles is 10mm, thereby realize compact structure, met and had the design of the injection mold hot runner of specific (special) requirements.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
