Abstract
The utility model discloses an improved structure of a hot runner die, which comprises a hot mold plate, a sleeve and a hot runner arranged in the sleeve and communicated with the cavity of the die, wherein a gap is reserved between the hot mold plate and the sleeve; the sleeve is integrally formed by a main runner sleeve and a nozzle sleeve; a plurality of round holes are formed at one end of the sleeve facing towards the cavity; and a cold runner between the nozzle of the hot runner and the cavity is arranged in a hot mold plate of the hot runner. Due to the adoption of the improved structure, the diameter of the hot runner is enlarged, plastic flowing is facilitated, not only the excessive heat quantity dissipation at the nozzle of the hot runner is prevented, but also wire drawing phenomenon at the nozzle is avoided, and at the same time, the die quality is effectively improved.
Description
Technical field
The utility model relates to the injection mold field, relates in particular to a kind of structure-improved of hot runner mould.
Background technology
In the cast structure of the hot runner mould of routine,, cause the nozzle place wire drawing, jaundice or curtain coating phenomenon to occur because nozzle place plastic cement temperature is too high.Processing method commonly used has: the cooling water channel of improvement nozzle place peripheral part, at hot runner manifold or nozzle place backflow relief chamber etc. is set.But through these mould structure complicacies of improving one's methods and making, the manufacturing cost of hot runner mould is expensive.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of structure-improved of hot runner mould, and this is simple and practical, and manufacturing cost is lower, can avoid the wire drawing phenomenon at nozzle place, improves die quality.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of structure-improved of hot runner mould; Comprise hot-die plate, lining and be located in the said lining and the hot flow path that is connected with the die cavity of mould; Be formed with the gap between said hot-die plate and the said lining; Said lining is that sprue bush and nozzle lining are one-body molded, thereby strengthens the hot flow path diameter, helps plastic cement to flow; And said lining offers several circular holes on an end of die cavity, can prevent that the heat at the nozzle place of hot flow path too much scatters and disappears; Be provided with cold runner between the nozzle of said hot flow path and the said die cavity, said cold runner is located in the hot-die plate of said hot flow path.
As the further improvement of the utility model, said circular hole is located at the dual-side place of said lining near said hot-die plate.
The beneficial effect of the utility model is: through the lining with sprue bush and the one-body molded integral body of nozzle lining; On an end of die cavity, offer several circular holes at this lining; And be provided with cold runner between the nozzle of hot flow path and the die cavity, this cold runner also is located in the hot-die plate of hot flow path.Compared to prior art, the utility model can strengthen the hot flow path diameter, thereby helps plastic cement to flow, and can prevent that the heat at hot flow path nozzle place too much scatters and disappears, and avoids occurring nozzle place wire drawing phenomenon, has improved die quality effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Structure improved embodiment to the hot runner mould of the utility model is elaborated with reference to the accompanying drawings.
The structure-improved of the described a kind of hot runner mould of the utility model; Comprise hot-die plate 1, lining 2 and be located in the said lining and the hot flow path 3 that is connected with the die cavity of mould; Be formed with the gap between said hot-die plate and the said lining; Said lining is that sprue bush and nozzle lining are one-body molded, thereby can strengthen the hot flow path diameter, helps plastic cement to flow; And said lining offers several circular holes 5 towards an end of die cavity, can prevent that the heat at the nozzle place of hot flow path too much scatters and disappears; Be provided with cold runner 4 between the nozzle of said hot flow path and the said die cavity, said cold runner is located in the hot-die plate 1 of said hot flow path.
In the present embodiment, said circular hole is located at the dual-side place of said lining near said hot-die plate.
