Abstract

A radiating lining of a hot sprue comprises a radiating lining body which is formed by a first lining and a second lining, wherein the first lining is sleeved on the periphery of a hot sprue body, the second lining is sleeved on the first lining corresponding to the position of a tip of the hot sprue, and the first lining and the second lining are in thread matching connection through a thread section. A first boss and a second boss are arranged at the end portions of the first lining and the second lining, the end portions of the first lining and the second lining are matched to each other, and the thread section is arranged between the first boss and the second boss. By means of the radiating lining of the hot sprue, the problems of salivation of a hot sprue core, wire drawing and material wire breakage caused by poor radiating performance of the radiating lining and unstable temperature of the hot sprue in the injection molding process are solved.

Description

A kind of hot mouth heat radiation lining
Technical field
The utility model belongs to the TOP-TIP field, relates to a kind of hot mouth heat radiation lining.
Background technology
Hot runner mould is plastic material injection forming mold commonly used at present.Common hot runner mould comprises a hot mouth main body, is positioned at the sharp-tongued of hot mouth main body end, hot mouth main body and sharp-tongued in be provided with the runner of connection, the melt plastic cement that is positioned at runner is extruded by hot mouth, injects mold cavity, is shaped to product.Be provided with the heat radiation lining in hot mouth main body and sharp-tongued outer race.Heat radiation lining commonly used as shown in Figure 1, this heat radiation lining 1 corresponding hot mouth body position and corresponding sharp-tongued position are integrated formation.This heat radiation lining 1 uses steel matter integrally casting to form.In injection molding process, hot mouth high temperature melts state so that the plastics in the runner are heat, because heat radiation lining 1 is the steel matter, thermal diffusivity is bad, and it is bad to cause dispelling the heat, and hot mouth temperature is unstable, after injection moulding is finished, when mould is opened the demoulding, the material excess Temperature at hot mouth mouth core Jiao Kou place, the easy wire drawing of stub bar; Or cause hot mouth mouth core salivation, if the fracture head will appear in stub bar and product junction excess Temperature, these problems all can affect the moulding of next product.
Therefore, how addressing the above problem, is the content that the utility model will be studied.
Summary of the invention
The utility model provides a kind of hot mouth heat radiation lining, and its purpose mainly is to solve in injection moulding process, because heat radiation lining thermal diffusivity is bad, hot mouth temperature is unstable and cause the problem of the salivation of hot mouth mouth core, wire drawing and the fracture of material silk.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hot mouth heat radiation lining, comprise the heat radiation lining, described heat radiation lining is comprised of the first lining and the second lining, described the first lining is set in the periphery of hot mouth body, and the sharp-tongued position of the corresponding hot mouth of described the second lining is set in described the first lining; Connect through the thread segment threaded engagement between described the first lining and the second lining.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the end that described the first lining and the second lining match is provided with the first boss and the second boss, and described thread segment is arranged between described the first boss and the second boss.
2, in the such scheme, in described the first boss and the second boss, the first boss is outer lug boss, is arranged on the end of the first lining, and described the second boss is inner convex platform, is arranged on the end of the second lining.Wherein, described " outer lug boss " refers to the boss of establishing at the external diameter side face of the first lining; Described " inner convex platform " refers to the boss of establishing at the internal diameter side face of the second lining.
3, in the such scheme, described the first lining is steel matter lining, and described the second lining is the copper material lining.
Because the utilization of the technical program, the utility model compared with prior art has following advantages:
1, owing to being connected by the first lining and the second bush threads, heat radiation lining of the present utility model consists of, the sharp-tongued position of the corresponding hot mouth of the second lining arranges, and adopt the copper material of good heat dispersion performance to make, the second lining of this copper material directly contacts cooperation with mould, so that good heat dissipation effect, the first lining wraps hot mouth body and the sharp-tongued integral body of hot mouth, can be good at keeping the temperature constant of hot mouth body constant, effectively solves the problem of the salivation of hot mouth mouth core, wire drawing and the fracture of material silk.
2, the utility model is simple in structure, practical, and easy to process, and processing cost is lower.
Description of drawings
Accompanying drawing 1 is the prior art structural representation;
Accompanying drawing 2 is the utility model structural representation.
In the above accompanying drawing: 1, heat radiation lining; 2, the first lining; 3, the second lining; 4, the first boss; 5, the second boss.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment:
As shown in Figure 2, a kind of hot mouth heat radiation lining comprises heat radiation lining 1, and described heat radiation lining 1 is comprised of the first lining 2 and the second lining 3, described the first lining 2 is set in the periphery of hot mouth body, and the sharp-tongued position of described the second lining 3 corresponding hot mouths is set in described the first lining 2; Connect through the thread segment threaded engagement between described the first lining 2 and the second lining 3.
The end that described the first lining 2 and the second lining 3 match is provided with the first boss 4 and the second boss 5, and described thread segment is arranged between described the first boss 4 and the second boss 5.
Described the first boss 4 and the second boss 5 are among both, and the first boss 4 is outer lug boss, is arranged on the end of the first lining 2, and described the second boss 5 is inner convex platform, is arranged on the end of the second lining 3.
Heat radiation lining 1 of the present utility model is connected and composed by the first lining 2 and the second lining 3 threaded engagement, the sharp-tongued position of the second lining 3 corresponding hot mouths arranges, and adopt the copper material of good heat dispersion performance to make, the second lining 3 of this copper material directly contacts cooperation with mould, so that good heat dissipation effect, the first lining 1 wraps hot mouth body and the sharp-tongued integral body of hot mouth, can be good at keeping the temperature constant of hot mouth body constant, effectively solves the problem of the salivation of hot mouth mouth core, wire drawing and the fracture of material silk.Hot mouth body and sharp-tongued being of hot mouth illustrate among the figure.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
