Abstract
The utility model discloses a shower nozzle of needle valve formula hot runner, it includes the shower nozzle body, has the shower nozzle mouth in the one end of shower nozzle body, the cross sectional shape of shower nozzle mouth is circular, the same axial position of shower nozzle mouth is equipped with three or four direction pieces, the direction piece is fixed with the inside wall of shower nozzle mouth respectively to evenly distributed is in the shower nozzle mouth. And the connection parts of the guide pieces and the inner side wall of the nozzle opening are respectively provided with a connection edge which radially expands towards the nozzle opening. The inner side of the guide plate close to the axis of the nozzle opening is arc-shaped. Adopt above-mentioned technical scheme, the utility model discloses a shower nozzle of needle valve formula hot runner has set up behind three or four guide vanes, and the shower nozzle adopts and joins in marriage plastics with the needle and follow the even feeding of three point. The problem of uneven flow of the plastic at the nozzle in the prior art can be solved. Meanwhile, the generation of dead corners can be reduced, and the product quality is improved.
Description
Technical field
The utility model relates to a kind of needle valve hot flow path, the shower nozzle of a kind of needle valve hot flow path of more specifically saying so.
Background technology
The hot flow path technology is a kind of advanced technology that is applied to plastic injection mold cast flow passage system, is a focus direction of injection molding technological development.Hot runner mould is at electronics, automobile, and medical treatment, commodity, toy, packing, building, each industrial department such as office equipment all is used widely.Hot flow path is divided into open and needle valve.The needle valve hot flow path comprises hot runner manifold, nozzle, temperature controller and auxiliary component.Nozzle comprises shower nozzle, is provided with needle in the shower nozzle, and cylinder or spring promote the injection moulding of the opening and closing realization of needle-valve to the hot flow path die cavity by controller and time schedule controller control cylinder.The needle valve hot flow path has the saving material, plastic surface aesthetic, tight, the intensity advantages of higher of internal soundness simultaneously.
The shower nozzle of needle valve hot flow path is the critical component of hot runner molding, it comprises sprayer body, end at sprayer body has the shower nozzle mouth, the shower nozzle mouth of the shower nozzle of existing needle valve hot flow path is circular, leave certain space between circular shower nozzle mouth and the needle, because needle does not have certain stationarity at shower nozzle mouth place, makes the mobile inhomogeneous of plastics like this, has influenced the quality of injecting products.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of shower nozzle of mobile uniform needle valve hot flow path of plastics, to improve the quality of injecting products.
For achieving the above object, the utility model is by the following technical solutions: a kind of shower nozzle of needle valve hot flow path, it comprises sprayer body, end at sprayer body has the shower nozzle mouth, the cross sectional shape of described shower nozzle mouth is circular, the same axial location of described shower nozzle mouth is provided with three or four prerotation vanes, and described prerotation vane is fixed with the madial wall of shower nozzle mouth respectively, and is evenly distributed in the shower nozzle mouth.
Described prerotation vane is provided with to the fillet of shower nozzle bore to expansion with the junction of the madial wall of shower nozzle mouth respectively.Described prerotation vane is a circular arc near the inner edge of shower nozzle mouth axis.
After adopting technique scheme, the shower nozzle of needle valve hot flow path of the present utility model to be provided with three or four prerotation vanes, shower nozzle adopt with needle with joining plastics from 3 even chargings.Can overcome the prior art plastics in the mobile uneven problem of shower nozzle mouth.Simultaneously can reduce the generation at dead angle, improve product quality.
Description of drawings
Fig. 1 is the structural representation of the shower nozzle of the utility model needle valve hot flow path;
Fig. 2 is a kind of structural representation of shower nozzle mouth of embodiment;
Fig. 3 is the structural representation of the shower nozzle mouth of another kind of embodiment;
Among the figure: 1-sprayer body, 2-shower nozzle mouth, 3-prerotation vane, 4-fillet pyrometer fire-end, 5-inner edge.
The specific embodiment
As shown in Figure 1, the shower nozzle of needle valve hot flow path of the present utility model, it comprises sprayer body 1, has shower nozzle mouth 2 at an end of sprayer body, the cross sectional shape of described shower nozzle mouth 2 is circular.Above-mentioned feature is consistent with prior art, therefore, is not described in detail.
Referring to figure, Fig. 3, characteristics as the shower nozzle of needle valve hot flow path of the present utility model are: the same axial location of described shower nozzle mouth 2 is provided with three or four prerotation vanes 3, described prerotation vane 3 is fixed with the madial wall of shower nozzle mouth 2 respectively, and is evenly distributed in the shower nozzle mouth 2.Described prerotation vane 3 is provided with fillet 4 to shower nozzle mouth 2 radial expansion with the junction of the madial wall of shower nozzle mouth 2 respectively.Described prerotation vane 3 is a circular arc near the inner edge 5 of shower nozzle mouth 2 axis.
