Abstract
The invention discloses an improved main injection nozzle. The improved main injection nozzle comprises a main injection nozzle body, wherein the axial middle part of the main injection nozzle is provided with a main fluid channel; the axial middle part of one end of the main injection nozzle body is provided with a gun nozzle matched circular arc which is communicated with the main fluid channel; four screw counter bores are formed in the main injection nozzle body, and are distributed uniformly around the axis of the main injection nozzle body; each screw counter bore comprises a counter bore and a passing hole; the circular arc of each counter bore is not crossed with the gun nozzle matched circular arc, so that the screw counter bores and the gun nozzle matched circular arc cannot break; the contact area of a gun nozzle and the main injection nozzle is large, and glue is unlikely to leak; the service life of a system can be prolonged.
Description
Technical field
The present invention relates to the not main nozzle of holes of a kind of improved main nozzle, particularly a kind of screw counterbore and big gun mouth fit circular arc.
Background technology
Main nozzle is the central module of TOP-TIP, and main nozzle injects flow distribution plate by plastic solution, and the plastic solution that flow distribution plate carrys out main nozzle transmission is again distributed to each injection nozzle through fluid passage, by injection nozzle, plastic solution is injected in the die cavity of mould.As shown in accompanying drawing 1,2, conventional main nozzle, comprises main nozzle body at present, and the axial middle part of described main nozzle body is provided with main fluid passageway; One end of described main nozzle body axially middle part is provided with big gun mouth fit circular arc, and described big gun mouth fit circular arc is communicated with described main fluid passageway; On described main nozzle body, offer four screw counterbores, described four screw counterbores are around the even branch of axis; Due to the center line of each screw counterbore and the center line of main nozzle body lean on too near, cause four screw counterbores by big gun mouth fit circular arc holes, also cause big gun mouth fit circular arc can not be processed into very large semicircle, therefore big gun mouth coordinates contact area too little with main nozzle, easily occurs leaking glue phenomenon.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed the not main nozzle of holes of a kind of screw counterbore and big gun mouth fit circular arc.
Technical solution of the present invention is achieved in that a kind of improved main nozzle, comprises main nozzle body; The axial middle part of described main nozzle body is provided with main fluid passageway; One end of described main nozzle body axially middle part is provided with big gun mouth fit circular arc, and described big gun mouth fit circular arc is communicated with described main fluid passageway; On described main nozzle body, offer four screw counterbores, described four screw counterbores are around the even branch of axis of main nozzle body; Described each screw counterbore comprises counter sink and by hole, the circular arc of described each counter sink and described big gun mouth fit circular arc are non-intersect.
Preferably, the cross section of described each counter sink is U-shaped.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The main nozzle of a modification of the present invention, four screw counterbores on main nozzle body have all radially outwards been offset to certain distance, make counter sink circular arc and the described big gun mouth fit circular arc of described screw counterbore non-intersect, therefore screw counterbore and big gun mouth fit circular arc can holes, big gun mouth and main nozzle contact area are large, do not allow leakiness glue, can extend system service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation of a kind of main nozzle that accompanying drawing 1 is prior art;
The A-A of a kind of main nozzle that accompanying drawing 2 is prior art to cutaway view;
The structural representation of the main nozzle that accompanying drawing 3 is a modification of the present invention;
The B-B of the main nozzle that accompanying drawing 4 is a modification of the present invention to cutaway view;
Wherein: 1, main nozzle body; 2, main fluid passageway; 3, screw counterbore; 4 big gun mouth fit circular arc; 5, counter sink; 6, pass through hole.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 3,4 is a kind of improved main nozzle of the present invention, comprises main nozzle body 1; The axial middle part of described main nozzle body 1 is provided with main fluid passageway 2; One end of described main nozzle body 1 axially middle part is provided with big gun mouth fit circular arc 4, and described big gun mouth fit circular arc 4 is communicated with described main fluid passageway 2; On described main nozzle body 1, offer four screw counterbores 3, described four screw counterbores 3 are around the even branch of axis of main nozzle body 1; Described each screw counterbore 3 comprises counter sink 5 and by hole 6, the cross section of described each counter sink 5 is U-shaped; The circular arc of described each counter sink 5 and described big gun mouth fit circular arc 4 are non-intersect.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The main nozzle of a modification of the present invention, four screw counterbores on main nozzle body have all radially outwards been offset to certain distance, make counter sink circular arc and the described big gun mouth fit circular arc of described screw counterbore non-intersect, therefore screw counterbore and big gun mouth fit circular arc can holes, big gun mouth and main nozzle contact area are large, do not allow leakiness glue, can extend system service life.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
