Description
Technical field
The present invention relates to the hot runner mould technical field, relate in particular to a kind of hot nozzle assembly of hot flow path of directly colour changing.
Background technology
Hot runner mould is plastic material injection forming mold at present commonly used, with respect to the mould of cold runner structure, has and economizes in raw materials, and shortens the product molding cycle, reduces waste product, improves the quality of products, and eliminates subsequent handling, helps advantage such as the production automation.But, at present because there is certain deficiency in design in its hot mouth structure, causes molten plastic to be stranded in hot mouth easily and chew on the position, dead angle of point (as the corner A among Fig. 1), through long-time heating and the flavescence blackout, influence the color purity of injection moulding; When changing the different colours plastics, also need to discharge a large amount of new colored plastics and remove and be stranded in the native color plastics of chewing on the point, sometimes even discharge a large amount of new raw materials and also be difficult to the raw material at this position, dead angle is thoroughly got rid of.So not only cause the waste of raw material, and also influenced production efficiency and product quality.
Summary of the invention
For overcoming the problems referred to above, the present invention proposes a kind of hot nozzle assembly of hot flow path of directly colour changing, and molten plastic can be stranded on the hot mouth, can reduce product colour impurity, also makes the colour changing operation simpler, quick.
For achieving the above object, technical scheme proposed by the invention is: the direct hot nozzle assembly of the hot flow path of colour changing, comprise the sharp-tongued and abnormity nut of a heat, and it is characterized in that: described heat is sharp-tongued to be comprised body and chews point, is provided with a straight channel in the body; The described point of chewing offers the runner that a plurality of and described straight channel communicates; The outlet of this runner is positioned at chews sharp root, this exit chew the annular transition cambered surface that sharp surface is an indent; Described abnormity nut be placed in heat sharp-tongued on, its inner chamber front end matches with hot sharp-tongued body, terminal inner surface be one be in annular inverted cone surface.
Further, the inverted cone surface of described abnormity nut inner chamber end with chew sharp root and join, form one more than or equal to 90 ° angle.
Further, described runner and straight channel form an obtuse angle, and scope is at 90 ° ~ 135 °.
Preferably, described runner can have 2,3,4,5 or 6.
Beneficial effect of the present invention: the runner outlet is positioned at chews sharp root, and the annular transition cambered surface transition of indent is adopted on its surface, relevant position, does not have the material of stagnating dead point; Inverted cone surface in the abnormity nut washes away its adverse current to the reflection of molten plastic to chew the point surface, make that chewing sharp root atresia position molten plastic can obtain upgrading in the per injection process, thereby thoroughly solve the stagnant material problem of chewing in the point again; Can reduce product colour impurity, also make the colour changing operation simpler, quick, thorough, reduce raw-material waste, improve production efficiency and product quality.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Shown in Fig. 2-7, be the hot nozzle assembly of hot flow path of directly colour changing of the present invention, comprise a heat sharp-tongued 1,3 and one abnormity nut 2,4, described heat sharp-tongued 1,3 comprises body 11,31 and chews point 12,32, is provided with a straight channel 111,311 in the body 11,31; The described point 12,32 of chewing offers the runner 121,321 that a plurality of and described straight channel 111,311 communicates; 121,321 outlets of this runner are positioned at chews point 12,32 roots, this exit chew the annular transition cambered surface 122,322 that sharp surface is an indent; Described abnormity nut 2,4 is placed on the heat sharp-tongued 1,3, and its inner chamber front end and hot sharp- tongued body 11,31 match, terminal inner surface be one be in annular inverted cone surface 201,401.
Be depicted as the embodiment of the invention one as Fig. 2-4, it is chewed point 12 and offers 3 runners 121, forms 135 ° angle with straight channel 111 respectively; Runner 121 exits chew the annular transition cambered surface 122 that sharp 12 surfaces are an indent, this annular transition cambered surface 122 forms 135 ° angle with body 11 outer surfaces.The inner chamber front end of abnormity nut 2 just is complementary with sharp-tongued body 11 external diameters of heat, its terminal inner surface be one be in the annular inverted cone surface 201, the annular transition cambered surface 122 that its root and Re Zui chew sharp 12 roots is joined, form a right angle, the molten plastic that runner 121 penetrates reflects to form adverse current through inverted cone surface 201 can wash away the annular transition cambered surface 122 of chewing point 12, in time take away the raw material of chewing on the point 12, avoid producing the material phenomenon that stagnates.
Be depicted as the embodiment of the invention two as Fig. 5-7, it is chewed point 32 and offers 4 runners 321, forms 90 ° angle with straight channel 311 respectively; Runner 321 exits chew the annular transition cambered surface 322 that sharp 32 surfaces are an indent, this annular transition cambered surface 122 forms 135 ° angle with body 31 outer surfaces.The inner chamber front end of abnormity nut 4 just matches with sharp-tongued body 31 external diameters of heat, its terminal inner surface be one be in the annular inverted cone surface 401, the annular transition cambered surface 322 that its root and Re Zui chew sharp 32 roots is joined, form 135 ° angle, the molten plastic that runner 321 penetrates is through washing away the annular transition cambered surface 322 of chewing point 32 through the adverse current of inverted cone surface 401 reflections, in time take away the raw material of chewing on the point 32, avoid producing the material phenomenon that stagnates.
Wherein, what the angle of runner 121,321 and straight channel 111,311 can also be between 90 ° ~ 135 ° is arbitrarily angled, and its number can also 2,3,4,5 or 6 etc.
Operation principle of the present invention as shown in Figure 8, be example with embodiment one, after utilization is chewed molten plastic that sharp 12 runners 121 penetrate and is run into the inverted cone surface 201 of special-shaped nut 2, the reflection plastic adverse current 5 that produces, can reflex to and chew sharp 12 roots, inverted cone surface 201 because of special-shaped nut 2 is the surfaces that are annular in simultaneously, can produce the effect of annularly flow, makes the plastics of chewing sharp 12 root atresia positions obtaining upgrading in the injection process each time.Thereby thoroughly solve the stagnant material problem of chewing in the point 12.
Although specifically show and introduced the present invention in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in not breaking away from the spirit and scope of the present invention that appended claims limits; the various variations that the present invention is made are protection scope of the present invention in the form and details.
