Description
Technical field
The utility model relates to hot runner mould, injection molding art, in particular to one straight needle pouring heat 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 straight needle pouring gate structure is improved and is formed in existing technical foundation, new structure mainly for below prior art 2 improve: 1. for plastic product surface require high, use existing straight needle pouring gate structure, because guiding accuracy is not high, easily there is burr in product cast gate; 2. existing straight needle pouring gate structure can not Rapid Circulation and quick colour changing.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of straight needle pouring heat 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 straight needle pouring heat runner nozzle, comprise mouth core and sprue bush that coaxial sleeve is connected on inside, nozzle body one end, first flow is offered in described nozzle body, described mouth in-core offers the second runner, described second runner is connected with first flow, needle is provided with between described first flow and the second runner, described needle and described first flow, space is left between second runner, described second runner end profile offers multiple side runner, described multiple side runners are communicated in the space that formed between described sprue bush and described mouth core, and be communicated in cast gate, needle passes mouth core end and is arranged on cast gate place.
Further, the diameter of described needle first flow section is greater than the diameter of its second flow channel section.
Preferably, the mouth outer core in described side runner exit offers curved sluice way respectively.
The beneficial effects of the utility model are:
The utility model have employed knockdown structure, the single circular port vertical with nozzle body runner hole is formed after fit with nozzle main body and sprue bush, make plastic material can only fill toward a direction flowing like this, and there is no dead angle completely, the object than faster colour changing can be reached.Needle is in active procedure simultaneously, and mouth core plays again the effect of accurately guiding, can reach splendid cast gate outward appearance object.
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 straight needle pouring heat runner nozzle arrangements schematic diagram;
Fig. 2 mouth cored 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 straight needle pouring heat runner nozzle, comprise mouth core 1 and sprue bush 2 that coaxial sleeve is connected on inside, nozzle body 3 one end, first flow 31 is offered in described nozzle body 3, the second runner 11 is offered in described mouth core 1, described second runner 11 is connected with first flow 31, needle 4 is provided with between described first flow 31 and the second runner 11, described needle 4 and described first flow 31, space is left between second runner 11, described second runner 11 end profile offers multiple side runner 12, described multiple side runners 12 are communicated in the space 5 that formed between described sprue bush 2 and described mouth core 1, and be communicated in cast gate 6, needle 4 passes mouth core 1 end and is arranged on cast gate 6 place.
Further, the diameter of described needle 4 first flow section is greater than the diameter of its second flow channel section.
With reference to shown in Fig. 2, preferably, mouth core 1 outer wall in described side runner 12 exit offers curved sluice way 13 respectively.
The function of nozzle body 3: 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 1: 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 the single circular port vertical with nozzle body runner hole, makes the flowing of plastic material more smooth and easy like this, and does not have dead angle completely, can reach the object than faster colour changing.Needle is in active procedure simultaneously, and mouth core plays again the effect of accurately guiding, can reach splendid cast gate outward appearance object.
Secondly the function of sprue bush 2: fix mouth core by step surface, and the effect compressed are coordinate sealing with mould.
The function of needle 4: in injecting products process, opens or closes the object of cast gate.
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.
