Abstract
The utility model discloses a nozzle for hot runners, which comprises a nozzle body, a nozzle head and a nozzle core, wherein the nozzle core is arranged between the nozzle body and the nozzle head, and a heat insulating layer is arranged between the nozzle head and the nozzle core. According to the utility model, due to the setting of the heat insulating layer, the area (contacted with the nozzle core) of the nozzle head is reduced, thereby slowing down the rate of heat loss, avoiding the occurrence of a situation that a plastic melt has a curing phenomenon in the process of injection molding, effectively preventing the plastic melt (remaining in the nozzle core after the injection molding is completed) from continuing to flow outwards, and then avoiding the occurrence of a wire drawing phenomenon or a nozzle head blocked phenomenon; and meanwhile, the nozzle for hot runners has an advantage of saving energy and raw materials.
Description
Technical field
The utility model relates to a kind of TOP-TIP, particularly a kind of nozzle of hot flow path.
Background technology
TOP-TIP is owing to have the product of shortening molding cycle, saving plastic raw materials, minimizing expense article; Improve the quality of products, help advantages such as the production automation, expansion injection molding process range of application, each industrially developed country and area all obtain using very widely in the world today.
TOP-TIP mainly is made up of nozzle, flow distribution plate and temperature controller, and wherein nozzle comprises nozzle body, nozzle head and nozzle core.When prior art is carried out the nozzle assembling; Because nozzle core contacts through face with nozzle head and assembles; Heat transmission between the two is rapid; Because the lost plastic melt of nozzle core and nozzle head contact site that makes of heat has the trend of curing, thereby cause the nozzle head blocking and influence normal injection moulding work or be easy to occur the wire drawing phenomenon; In addition, after injection moulding was accomplished, because that nozzle head contacts with nozzle body is too tight, the plastic melt that nozzle core inside retains can continue outside outflow, thereby owing to the existence of curtain coating phenomenon forms wire drawing or generation waste material head, wastage of material is serious.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of nozzle of hot flow path, to avoid wire drawing or curtain coating phenomenon occurring owing to heat scatters and disappears fast.
For achieving the above object, the technical scheme of the utility model is following:
A kind of nozzle of hot flow path comprises nozzle body, nozzle head and the nozzle core between said nozzle body and nozzle head, is provided with thermal insulation layer between said nozzle head and the nozzle core.
Preferably, said thermal insulation layer is the groove that is opened in said nozzle core surface.
Preferably, said thermal insulation layer is the groove that is opened in said nozzle head inner surface.
Preferably, said thermal insulation layer is for be opened in the combination of the groove of said nozzle core outer surface and nozzle head inner surface simultaneously.
Preferably, the thickness of said thermal insulation layer is 0.5～1mm.
Pass through technique scheme; The nozzle of the hot flow path that the utility model provides, owing to offer groove on the surface of nozzle core, after the nozzle head assembling; Between nozzle head and nozzle core, form cavity, this cavity is has the thermal insulation layer that slows down the lost speed of heat.Compare prior art; Reduced the contact area of nozzle head and nozzle core owing to the existence of this thermal insulation layer; Thereby slowed down the lost speed of heat, avoided occurring the curing phenomenon of plastic melt, thereby avoided the phenomenon of wire drawing phenomenon or plug nozzle head to occur at injection moulding process; In addition, after injection moulding stopped, the existence of this thermal insulation layer can prevent effectively that the plastic melt that nozzle core inside retains from continuing outside curtain coating, had avoided serious wire drawing phenomenon or had produced bigger waste material head, had the advantage that economizes in raw materials.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is the nozzle arrangements sketch map of the disclosed a kind of hot flow path of the utility model embodiment.
Numeral among the figure:
11. nozzle body 12. nozzle heads 13. thermal insulation layers 14. nozzle cores
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
According to Fig. 1, the nozzle of the hot flow path that the utility model provides comprises nozzle body 11, nozzle head 12 and the nozzle core 14 between nozzle body 11 and nozzle head 12, is provided with thermal insulation layer 13 between nozzle head 12 and the nozzle core 14.
Wherein, thermal insulation layer 13 is for being opened in the groove of nozzle core 14 outer surfaces, and perhaps for being opened in the groove of nozzle head 12 inner surfaces, perhaps for being opened in the combination of the groove of nozzle core 14 outer surfaces and nozzle head 12 inner surfaces simultaneously, its thickness is 0.5～1mm.
The nozzle of the hot flow path that the utility model provides; Owing between nozzle head 12 and nozzle core 14, be provided with groove; After nozzle head 12 assemblings, between nozzle head 12 and nozzle core 14, form cavity, this cavity is has the thermal insulation layer 13 that slows down the lost speed of heat.Compare prior art; Reduced the contact area of nozzle head 12 and nozzle core 14 owing to the existence of this thermal insulation layer 13; Thereby slowed down the lost speed of heat, avoided occurring the curing phenomenon of plastic melt, thereby avoided the phenomenon of wire drawing phenomenon or plug nozzle head 12 to occur at injection moulding process; In addition, after injection moulding stopped, the existence of this thermal insulation layer 13 can prevent effectively that the plastic melt that nozzle core 14 inside retain from continuing outside curtain coating, had avoided serious wire drawing phenomenon or had produced bigger waste material head, had the advantage that economizes in raw materials.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
