Abstract
The utility model discloses a plasticized spray nozzle for an injection molding machine. The plasticized spray nozzle is characterized in that a feeding pipeline with the diameter being 13-15m is arranged in a spray nozzle body in a penetrating manner, and the pipe diameter of one end of the feeding pipeline is gradually shrunk to form a conical surface; the top end of the conical surface continues to extend to form a pointed injection nozzle with the diameter being 2-3mm to penetrate out of the spray nozzle body. The plasticized spray nozzle has a simple structure, has small pressure loss in the melt flowing process and a large feeding action, is not easy to generate a retained material decomposition phenomenon, and meanwhile is convenient for cleaning. The pipeline is closed not to leak.
Description
Technical field
The utility model relates to a kind of injection machine, is specifically related to a kind of Plasticized component.
Background technology
Nozzle is the attaching parts of Plasticized component and mould running channel, its major function prevents curtain coating and sets up back pressure while being preformed, guarantee plasticizing capacity and improve plasticizing quality, build-up pressure, raising shear effect and melt temperature during injection, improve viscosity and make the further homogenizing of melt, during pressurize, carry out pressurize feeding.Present most of nozzle adopts locked, can check nozzle when preformed runner, and can under injection pressure effect, automatically open when injection moulding, make melt enter mould rifle, but block because this structure easily causes locking, make nozzle interior flow of melt resistance large, easily produce stagnant material, the melt of delay easily decomposes, not easy cleaning, each part coordinates and is difficult for precision simultaneously, produces and leaks.
Summary of the invention
Utility model object: the purpose of this utility model is in order to overcome the deficiencies in the prior art, and the plasticizing nozzle for injection machine of the stagnant material decomposing phenomenon of a kind of difficult generation is provided.
Technical scheme: a kind of plasticizing nozzle for injection machine of the utility model, in nozzle body, be penetrated with the feed pipe that diameter is 13 ~ 15mm, the caliber gradually closing of described feed pipe one end forms taper seat, the top of taper seat continues to extend, and the injection sharp nozzle that formation diameter is 2 ~ 3mm passes described nozzle body; This kind of structure nozzle passage is level and smooth, without hindrance, and flow resistance is little, and in the process that melt is extruded at nozzle, the pressure loss is little, is therefore difficult for causing stagnant material.
Preferably, the bus on described taper seat and the angle of center line are 60 °, and it is the most smooth and easy laborsaving that melt enters injection sharp nozzle.
Preferably, the length of described injection sharp nozzle is 8 ~ 10mm.
Tightr for nozzle is contacted with mould, the one end being passed by described injection sharp nozzle on described nozzle body is sphere.
In order further to strengthen the cooperation positioning relation of nozzle and mould main flow cover, described spherical radius is 20 ~ 25mm.
Beneficial effect: the utility model is simple in structure, in the melt process of circulation, the pressure loss is little, and feeding effect is large, is difficult for producing stagnant material decomposing phenomenon, is convenient to clean simultaneously, and pipeline closed can not produce leakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
embodiment:a kind of plasticizing nozzle for injection machine, in nozzle body 1, being penetrated with diameter is the feed pipe 2 of 14mm, feed pipe 2 one end caliber gradually closings form taper seat 3, bus on taper seat 3 and the angle of center line are 60 °, the top of taper seat 3 continues to extend, the injection sharp nozzle 4 that formation diameter is 2mm passes nozzle body 1, and the length of injection sharp nozzle 4 is 9mm, and the one end being passed by injection sharp nozzle 4 on nozzle body 1 is the sphere of radius 23mm.
This kind of structure nozzle passage is level and smooth, without hindrance, and flow resistance is little, and in the process that melt is extruded at nozzle, the pressure loss is little, is therefore difficult for causing stagnant material.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Not departing under the spirit and scope prerequisite of the present utility model of claims definition, can make in the form and details various variations to it.
