Description
Technical field
The utility model relates to hot runner mould, injection molding art, in particular to a kind of high temperature resistant type spot pouring mouth hot-runner nozzle.
Background technology
Hot-runner nozzle uses in injection mold, along with the development of injection mold, hot flow path is generally applied in injection mold, hot-runner nozzle is indispensable important component part in hot flow path, the nozzle of new this pin-point gate structure improve and is formed in existing technical foundation, new structure mainly for below prior art 2 improve: 1. existing pin-point gate structure mouth core material is easier to wear and tear at the shaping glass fiber plastic product time ratio that adds.2. existing structure sprue bush is when shaped article, can leave cold burden section.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of high temperature resistant type spot pouring mouth hot-runner nozzle.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of high temperature resistant type spot pouring mouth hot-runner nozzle, comprise mouth core and sprue bush that coaxial sleeve is connected on inside, nozzle body one end, mouth core one end embeds in described nozzle body, the other end is cone end, described cone end is surrounded by described sprue bush, and leave gap, first flow is offered in described nozzle body, described mouth in-core offers the second runner, described second runner is connected with first flow, the taper seat of described cone end offers respectively three runner holes, three described runner holes are connected with the second runner, each runner axially bored line and the second runner axis are acute angle.
Further, described three runner holes are evenly distributed on described taper seat.
The beneficial effects of the utility model are:
The utility model have employed knockdown structure, what formed after fit with nozzle main body and sprue bush is three circular ports angled with mouth core second runner, make the flowing of plastic material more smooth and easy like this, briquetting pressure can be much little, very little cast gate trace is left on shaped article surface, the thermal conductivity of mouth core application simultaneously, wear-resistant better material, thus splendid cast gate outward appearance object can be reached.Because sprue bush directly extends to cast gate place, can be good at the temperature keeping cast gate place, and sprue bush is easily changed.Apply this structure, completely can shaping good fluidity, plastics that MFI is high and add low glass fiber product, do not have cold burden section simultaneously.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, and form a application's part, schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 high temperature resistant type spot pouring mouth hot runner nozzle structure schematic diagram.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Fig. 1, a kind of high temperature resistant type spot pouring mouth hot-runner nozzle, comprise mouth core 10 and sprue bush 20 that coaxial sleeve is connected on inside, nozzle body 30 one end, mouth core 10 one end embeds in described nozzle body 30, the other end is cone end 11, described cone end 11 is surrounded by described sprue bush 20, and leave gap, first flow 31 is offered in described nozzle body 30, the second runner 12 is offered in described mouth core 10, described second runner 12 is connected with first flow 31, the taper seat of described cone end 11 offers respectively three runner holes 13, three described runner holes 13 are connected with the second runner 12, each runner hole 13 axis and the second runner 12 axis are acute angle.
Further, described three runner holes 13 are evenly distributed on described taper seat.
The function of nozzle body 30: coordinate heater to keep steady temperature, connect flow distribution plate runner, for plastic material provides flowable passage; Fixing mouth core and sprue bush.
Secondly the function of mouth core 10: enter mold cavity to plastic material and play guide functions is heat transfer; What formed after fit with nozzle main body and sprue bush is three circular ports angled with mouth core second runner, make the flowing of plastic material more smooth and easy like this, briquetting pressure can be much little, very little cast gate trace is left on shaped article surface, the thermal conductivity of mouth core application simultaneously, wear-resistant better material, thus splendid cast gate outward appearance object can be reached.
Secondly the function of sprue bush 20: fix mouth core by step surface, and the effect compressed are coordinate sealing with mould.Because sprue bush directly extends to cast gate place, can be good at the temperature keeping cast gate place, and sprue bush is easily changed.Apply this structure, completely can shaping good fluidity, plastics that MFI is high and add low glass fiber product, do not have cold burden section simultaneously.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
