Description
Technical field
The utility model relates to hot runner mould, injection molding art, in particular to a kind of single-orifice 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 is mainly improved for below prior art: 1. require high for plastic product surface, use existing pin-point gate structure, owing to leaving very large cast gate trace on shaped article surface, there are 3 percussion marks on shaped article surface simultaneously, mouth is sheared too large, product turns to be yellow.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of single-orifice type mouth core 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 single-orifice 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 runner hole, runner hole is connected with the second runner, and runner axially bored line and the second runner axis are acute angle.
Preferably, described runner hole exits is arranged in sprue bush inwall.
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 the single runner hole (diameter in hole according to moulding material and cast gate size determine) angled with mouth core second runner, very little cast gate trace is left on shaped article surface, there will not be 3 percussion marks at product surface, mouth shear heat is little, reduce the risk of product jaundice, splendid cast gate outward appearance object can be reached.
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.

Fig. 1 single-orifice 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 utility model in detail.
With reference to shown in Fig. 1, a kind of single-orifice 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 runner hole 13, runner hole 13 is connected with the second runner 12, runner hole 13 axis and the second runner 12 axis are acute angle.
The outlet of described runner hole 13 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 main body and sprue bush is the single runner hole (diameter in hole according to moulding material and cast gate size determine) angled with mouth core second runner, very little cast gate trace is left on shaped article surface, there will not be 3 percussion marks at product surface, mouth shear heat is little, reduce the risk of product jaundice, 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.
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.
