Abstract
A nozzle core structure of a hot nozzle comprises a nozzle core and a nozzle core sleeve. A runner is arranged in the nozzle core, the nozzle core sleeve is arranged at the front end of the nozzle core, and the nozzle core and the nozzle core sleeve are integrated. The nozzle core and the nozzle core sleeve of the hot nozzle are designed to be a whole and are integrated in manufacture. The integral peripheral face of the nozzle core and the nozzle core sleeve is the contact face contacted with a mould, so that contact area of the nozzle core structure and the mould is increased. Due to the fact that the nozzle core structure is manufactured by materials with good heat conductivity, the nozzle core structure is quick in integral heat dissipation. Material flow in a nozzle core runner is not high in temperature. For plastics not requiring high temperature, the nozzle core structure effectively resolves the problems of salivation, thread drawing and material thread fracture of the nozzle core of the hot nozzle in injection molding.
Description
Technical field
The invention belongs to the TOP-TIP field, relate to a kind of hot mouth mouth cored structure, this mouth cored structure do not need to be specially adapted to the very plastics of high-temperature.
Background technology
Hot runner mould is plastic material injection forming mold commonly used at present.Common hot runner mould comprises hot mouth main body, mouth core and a mouth core retainer plate, and the mouth core is arranged at the end of hot mouth body inner flow passage, and the mouth core retainer plate is sheathed on the mouth core, and the end of mouth core retainer plate protrudes in hot mouth body.The melt plastic cement that is positioned at runner is extruded by hot mouth, injects mold cavity, is shaped to product.
Hot mouth mouth cored structure commonly used is as shown in Figure 1, comprises mouth core 1, is provided with the runner 2 that is communicated with hot mouth runner in the mouth core 1, and the front end sleeve of mouth core 1 is provided with mouth core retainer plate 3.Wherein mouth core 1 select for use thermal conductivity preferably material process.In injection molding process, because the thermal conductivity of mouth core 1 is better, the materials flow temperature in the runner of mouth core 1 under the molten condition is higher, does not need very high plastics for temperature, and this mouth cored structure will cause mouth core hydrostomia easily; After injection moulding was accomplished, when the moulds open demoulding, the materials flow temperature at hot mouth mouth core place was too high, the easy wire drawing of stub bar; If stub bar and product junction temperature are too high, the fracture head will appear, and these problems all can influence the moulding of next product.
Therefore, how addressing the above problem, is the content that the present invention will study.
Summary of the invention
The present invention provides a kind of hot mouth mouth cored structure, and its purpose mainly is to solve in the prior art, to not needing the plastics of higher temperature, because hot mouth mouth core place's materials flow temperature is higher, causes the problem of hot mouth mouth core hydrostomia, wire drawing and the fracture of material silk.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of hot mouth mouth cored structure comprises mouth core and mouth core retainer plate; Said mouth in-core is provided with runner, and said mouth core retainer plate is located at the front end of mouth core; Said mouth core and mouth core retainer plate are that one constitutes.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the stage casing of the periphery surface of said mouth core is provided with thread segment.This thread segment is used for being connected with hot mouth main body.
2, in the such scheme, said mouth core is the contact-making surface that contacts with mould with the overall peripheral face of mouth core retainer plate.
3, in the such scheme, the integral body that said mouth core and mouth core retainer plate constitute all adopt thermal conductivity preferably material process.
Because the utilization of present technique scheme, the present invention compared with prior art has advantage:
1, because the present invention is designed to an integral body with hot mouth mouth core and mouth core retainer plate; One constitutes during manufacturing, and the mouth core is the contact-making surface that contacts with mould with the overall peripheral face of mouth core retainer plate, makes the contact area of this mouth cored structure and mould increase; Since this structural entity all adopt thermal conductivity preferably material process; Make that its integral heat sink is fast, the materials flow temperature in the mouth core runner is not high, for the plastics that do not need higher temperature; When injection moulding, this kind mouth cored structure has effectively solved the problem of hot mouth mouth core hydrostomia, wire drawing and the fracture of material silk.
2, the present invention is simple in structure, practical; And easy to process, processing cost is lower.
Description of drawings
Accompanying drawing 1 is the prior art structural representation;
Accompanying drawing 2 is structural representation of the present invention.
In the above accompanying drawing: 1, mouth core; 2, runner; 3, mouth core retainer plate; 4 thread segments.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment:
As shown in Figure 2, a kind of hot mouth mouth cored structure comprises mouth core 1 and mouth core retainer plate 3; Be provided with runner 2 in the said mouth core 1, said mouth core retainer plate 3 is located at the front end of mouth core 1; Said mouth core 1 constitutes for one with mouth core retainer plate 3.
The periphery surface stage casing of said mouth core 1 is provided with thread segment 4.
Said mouth core 1 is the contact-making surface that contacts with mould with the overall peripheral face of mouth core retainer plate 3.
Hot mouth mouth core 1 is designed to an integral body with mouth core retainer plate 3; One constitutes during manufacturing; The contact-making surface of the overall peripheral face of mouth core 1 and mouth core retainer plate 3 for contact with mould makes the contact area increase of this mouth cored structure and mould, owing to this structural entity all adopt thermal conductivity preferably material process; Make that its integral heat sink is fast, the materials flow temperature in the mouth core runner is not high.For the plastics that do not need higher temperature, when injection moulding, this kind mouth cored structure has effectively solved the problem of hot mouth mouth core hydrostomia, wire drawing and the fracture of material silk.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
