Abstract
The invention discloses a hot runner nozzle of a pin-point gate. The hot runner nozzle of the pin-point gate comprises a gate bush which is coaxially connected to one end of a nozzle body; a torpedo-shaped nozzle core is coaxially connected into the gate bush and is of a fusiform structure; three runners with arc-shaped sections are axially formed in the surface of the nozzle core; one end of the torpedo-shaped nozzle core is arranged outside the gate bush. The arc-shaped runners are formed in the nozzle core, so that a plastic material with relatively poor fluidity flows smoothly; meanwhile, a relatively quick color changing function can be achieved; the hot runner nozzle of the pin-point gate is relatively high in practicability.
Description
Technical field
The present invention relates to hot runner mould, injection moulding field, in particular to a kind of spot pouring mouth hot-runner nozzle.
Background technology
Hot-runner nozzle is used in injection mold, along with the development of injection mold, and generally application in injection mold of hot flow path, hot-runner nozzle is indispensable important component part in hot flow path.In prior art, there is following technical problem: 1, for the relatively poor plastic material of mobility, existing mouth cored structure flow resistance is relatively large.2, existing mouth cored structure colour changing fast.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, a kind of spot pouring mouth hot-runner nozzle is provided, improve the mobility of plastic material, realize quick colour changing.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of spot pouring mouth hot-runner nozzle, comprise the sprue bush that is coaxially connected to nozzle body one end, in sprue bush, be coaxially connected with torpedo type mouth core, described torpedo type mouth core is fusiformis structure, surface axially offers the runner of three arc sections, and described torpedo type mouth core one end is arranged on outside described sprue bush.
Further, described torpedo type mouth core is connected in the step forming between sprue bush and nozzle body by the boss arranging in outer rim in the middle.
The invention has the beneficial effects as follows:
The present invention has offered the runner of arc on mouth core, the relatively poor plastic material of mobility is flowed more smooth and easy, and can reach the colour changing function of fast speed, has higher practicality.
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, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.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, forms the application's a part, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is nozzle body cutaway view;
Fig. 2 is torpedo type mouth core perspective view;
Fig. 3 is torpedo type mouth core side view.
Number in the figure explanation: 1, torpedo type mouth core, 11,, runner, 12, boss, 2, sharp-tongued, 100, nozzle body, 200, sprue bush.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, a kind of spot pouring mouth hot-runner nozzle, comprise the sprue bush 200 that is coaxially connected to nozzle body 100 one end, in sprue bush 200, be coaxially connected with torpedo type mouth core 1, described torpedo type mouth core 1 is fusiformis structure, surface axially offers the runner 11 of three arc sections, and described torpedo type mouth core 1 one end is arranged on outside described sprue bush 200.
Described torpedo type mouth core 1 is connected in the step forming between sprue bush 200 and nozzle body 100 by the boss 12 arranging in outer rim in the middle.
Nozzle body 100 coordinates heater to keep steady temperature, connects flow distribution plate runner, for plastic material provides flowable passage.The step that nozzle body 100 and sprue bush 200 form is in order to fixing torpedo type mouth core 1.
1 pair of plastic material of torpedo type mouth core enters mold cavity and plays guide functions, is secondly to conduct heat.What after torpedo type mouth core 1 fit with nozzle main body 100 and sprue bush 200, form is the runner 11 of three arcs parallel with nozzle body 100 runner holes, make like this flowing of plastic material more smooth and easy, and there is no dead angle completely, can reach than the object of colour changing faster.
Sprue bush 200 is by the fixing mouth core of the step surface in nozzle body 100, and by the effect of its compression, is secondly to 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 modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
