Abstract
The utility model discloses a hot runner nozzle, which comprises a nozzle body, a nozzle head and a nozzle core arranged between the nozzle body and the nozzle head, wherein a part where the nozzle head is in contact with a mould is provided with a heat insulation groove. According to the hot runner nozzle provided by the utility model, because the heat insulation groove is arranged on the part where the nozzle head is in contact with the mould, contact area with the mould is reduced, thus heat loss during injection molding is reduced, the phenomenon that the nozzle head is blocked or wiredrawn due to easy solidification of plastics is avoided, and the injection molding efficiency is increased.
Description
Technical field
The utility model relates to a kind of TOP-TIP, particularly a kind of nozzle of TOP-TIP.
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 is established in the into corresponding mold injects mouth to accomplish injection moulding process through the nozzle head card.Prior art is directly the nozzle head card to be established in the progressive die tool; Because the contact area of nozzle head and mould is excessive; Heat transmission between the two is rapid; Because the lost plastic melt at nozzle head position 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.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of hot-runner nozzle, to reduce the contact area of nozzle head and mould, scatters and disappears thereby reduce heat.
For achieving the above object, the technical scheme of the utility model is following:
A kind of hot-runner nozzle comprises nozzle body, nozzle head and the nozzle core between said nozzle body and nozzle head, and the contact site with mould on the said nozzle head offers heat dam.
Preferably, said heat dam ringwise.
Pass through technique scheme; The hot-runner nozzle that the utility model provides; Because the position that on nozzle head, contacts with mould offers heat dam, reduced the contact area with mould, thus the thermal loss when having reduced injection moulding; Avoided occurring effectively having improved injection moulding efficient owing to plastics solidify nozzle head blocking or the wire drawing phenomenon that causes easily.
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 disclosed a kind of hot-runner nozzle structural representation of the utility model embodiment;
Fig. 2 is the sketch map of nozzle head shown in Fig. 1;
Fig. 3 is the sketch map of the disclosed another kind of nozzle head of the utility model embodiment.
Numeral among the figure:
11. nozzle body 12. nozzle heads 13. nozzle cores 21. heat dams 21 '. heat dam
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 and 2, the hot-runner nozzle that the utility model provides comprises nozzle body 11, nozzle head 12 and the nozzle core 13 between nozzle body 11 and nozzle head 12, and the contact site with mould on the nozzle head 12 offers heat dam 21.
Wherein, heat dam 21 ringwise.In addition, be present in mould contact surface if nozzle head 12 is long when long-pending excessive, can also on the basis of offering annular heat dam 21, offer heat dam as shown in Figure 3 21 ', scatter and disappear with further minimizing heat.
Pass through technique scheme; The hot-runner nozzle that the utility model provides; Because the position that on nozzle head 12, contacts with mould offers heat dam 21, reduced the contact area with mould, thus the thermal loss when having reduced injection moulding; Avoided occurring effectively having improved injection moulding efficient owing to plastics solidify nozzle head 12 blockings or the wire drawing phenomenon that causes easily.
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.
Claims (2)
1. a hot-runner nozzle comprises nozzle body, nozzle head and the nozzle core between said nozzle body and nozzle head, it is characterized in that the contact site with mould on the said nozzle head offers heat dam.
2. a kind of hot-runner nozzle according to claim 1 is characterized in that said heat dam ringwise.
