Abstract
The invention discloses a porous type nozzle core pin-point sprue hot runner spray nozzle comprising a nozzle core and a sprue bushing which are coaxially sleeved in one end of a spray nozzle body, one end of the nozzle core is embedded into the spray nozzle body, the other end of the nozzle core is a cone end, the bottom of the cone end is encircled by the sprue bushing, a first runner is formed in the spray nozzle body, a second runner is formed in the nozzle core, the second runner is communicated with the first runner, the conical surface of the cone end is respectively provided with three runner holes, the three runner holes are communicated with the second runner, and an included angle is formed between the axis of each runner hole and the axis of the second runner, and the included angle is an acute angle. According to the porous type nozzle core pin-point sprue hot runner spray nozzle disclosed by the invention, a combined structure is adopted, the three circular runner holes which have certain angles with the second runner of the nozzle core are formed after matching with the spray nozzle body and the sprue bushing, therefore, plastic materials are more smooth to flow and much lower in molding pressure; and very small sprue marks are formed on the surface of a molded product, so that the purpose of forming an extremely excellent sprue appearance can be achieved.
Description
Technical field
The present invention relates to hot runner mould, injection molding art, in particular to a kind of porous type mouth core 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 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 pin-point gate structure, owing to leaving very large cast gate trace on shaped article surface; 2. existing pin-point gate structure mouth core material is easier to wearing and tearing at shaping glass fiber plastic product time ratio.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of porous type mouth core spot pouring mouth hot-runner nozzle is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of porous type mouth core 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 bottom portion is surrounded by described sprue bush, 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.
Preferably, described runner hole exits is arranged in sprue bush inwall.
The invention has the beneficial effects as follows:
Present invention employs knockdown structure, what formed after fit with nozzle body and sprue bush is three the circular flow channel holes 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, can reach splendid cast gate outward appearance object.Simultaneously at shaping good fluidity, add low glass during the high plastic product of MFI, mouth core application thermal conductivity, wear-resistant good material, apply this structure, cast gate not easily blocks.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, 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 invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 porous type mouth core 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 present invention in detail.
With reference to shown in Fig. 1, a kind of porous type mouth core 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, surrounded by described sprue bush 20 bottom described cone end 11, 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.
Described runner hole 13 outlet is arranged in sprue bush 20 inwall.
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 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, and very little cast gate trace is left on shaped article surface, can reach splendid cast gate outward appearance object.Simultaneously at shaping good fluidity, add low glass during the high plastic product of MFI, mouth core application thermal conductivity, wear-resistant good material, apply this structure, cast gate not easily blocks.
Secondly the function of sprue bush 20: fix mouth core by step surface, and the effect compressed are coordinate sealing with mould.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
