Abstract
The utility model discloses a kind of high temperature resistant type oblique needle pouring heat runner nozzle, comprise the sprue bush that coaxial sleeve is connected on inside, nozzle body one end, first flow is offered in described nozzle body, the second runner is offered in described sprue bush, described second runner is connected with first flow, needle is provided with between described first flow and the second runner, space is left between described needle and described first flow, the second runner, needle end is arranged in the cone cavity of the second flow field end, and described cone cavity one end is cast gate.The utility model have employed knockdown structure, what formed after fit with nozzle main body and sprue bush is a circular port, make the flowing of plastic material more smooth and easy like this, briquetting pressure can be much little, the thermal conductivity of mouth core application simultaneously, wear-resistant better material, the splendid heat transfer of gate area avoids the plastics premature cure of gate area, thus can reach splendid cast gate outward appearance object.
Description
Technical field
The utility model relates to hot runner mould, injection molding art, in particular to a kind of high temperature resistant type oblique 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 pin-point gate structure is improved and is formed in existing technical foundation, new structure mainly for below prior art 3 improve: 1. existing pouring gate structure, client's die shaping add glass fiber plastic product time ratio be easier to wearing and tearing; 2., when forming the material of additive, existing cast gate temperature is lower; 3. existing oblique 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 high temperature resistant type oblique 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 high temperature resistant type oblique needle pouring heat runner nozzle, comprise the sprue bush that coaxial sleeve is connected on inside, nozzle body one end, first flow is offered in described nozzle body, the second runner is offered in described sprue bush, described second runner is connected with first flow, needle is provided with between described first flow and the second runner, space is left between described needle and described first flow, the second runner, needle end is arranged in the cone cavity of the second flow field end, and described cone cavity one end is cast gate.
Further, described needle end is truncated cone-shaped.
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 a circular port, make the flowing of plastic material more smooth and easy like this, briquetting pressure can be much little, the thermal conductivity of mouth core application simultaneously, wear-resistant better material, the splendid heat transfer of gate area avoids the plastics premature cure of gate area, thus can reach splendid cast gate outward appearance object.Sprue bush is changed convenient, and what minimizing client die gate part caused due to wearing and tearing reprocesses the risk of even scrapping.And sprue bush does not have dead angle, colour changing excellent.
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 overall 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 oblique needle pouring heat runner nozzle, comprise the sprue bush 20 that coaxial sleeve is connected on inside, nozzle body 30 one end, first flow 31 is offered in described nozzle body 30, the second runner 21 is offered in described sprue bush 20, described second runner 21 is connected with first flow 31, needle 10 is provided with between described first flow 21 and the second runner 31, described needle 10 and described first flow 21, space is left between second runner 31, needle 10 end is arranged in the cone cavity 22 of the second runner 31 end, described cone cavity 22 one end is cast gate 23.
Further, described needle 10 end is truncated cone-shaped.
The function of nozzle body 30: coordinate heater to keep steady temperature, connect flow distribution plate runner, for plastic material provides flowable passage; Fixing needle and sprue bush.
Secondly the function of sprue bush 20: 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 a circular port, make the flowing of plastic material more smooth and easy like this, briquetting pressure can be much little, the thermal conductivity of mouth core application simultaneously, wear-resistant better material, the splendid heat transfer of gate area avoids the plastics premature cure of gate area, thus can reach splendid cast gate outward appearance object.Sprue bush is changed convenient, and what minimizing client die gate part caused due to wearing and tearing reprocesses the risk of even scrapping.And sprue bush does not have dead angle, colour changing excellent.
The function of needle 10: 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.
