Abstract
The utility model discloses an open nozzle of an injection molding machine. A conical feeding pipeline penetrates through a nozzle body; a bottom circle of the conical surface has the diameter of 18-20mm; and the top end of the feeding pipeline continuously extends to form an injection nozzle with the diameter of 4-5mm so as to penetrate through the nozzle body. The open nozzle is simple in structure; and with the structure of the feeding pipeline, the melt is low in pressure loss and great in feeding effect during feeding, the bank decomposition phenomenon is difficultly caused, the pipeline is closed and is not leaked, and the nozzle is mainly used for processing high-viscosity and low-thermal stability plastics.
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 open type nozzle of the injection machine of the stagnant material decomposing phenomenon of a kind of difficult generation is provided.
Technical scheme: the open type nozzle of a kind of injection machine of the utility model, in nozzle body, be penetrated with the feed pipe of taper seat, the end circular diameter of described taper seat is 18 ~ 20mm, and the top of feed pipe continues to extend, and the injection nozzle that formation diameter is 4 ~ 5mm passes described nozzle body; Direction from feed end to injection nozzle, feed pipe gradually closing, changes gently, and the flow resistance of melt in feed pipe is little, and the pressure loss is little, is therefore difficult for causing stagnant material.
Preferably, the bus of described taper seat and the angle of center line are 15 ~ 20 °, guarantee mobile smooth and easy in feed pipe of melt.
Preferably, the length of described injection nozzle is 5 ~ 7mm, makes melt block, be detained extruding Shi Buhui.
Tightr for nozzle is contacted with mould, the one end being passed by described injection 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, the structure of feed pipe guarantees that melt pressure loss when charging is little, and feeding effect is large, is difficult for producing stagnant material decomposing phenomenon, pipeline closed can not produce leakage, is mainly used to process the plastics of high viscosity, poor heat stability.
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 open type nozzle of injection machine, in nozzle body 1, be penetrated with the feed pipe 2 of taper seat, the end circular diameter of taper seat is 19mm, the bus of taper seat and the angle of center line are 18 °, the top of feed pipe 2 continues to extend, the injection nozzle 3 that formation diameter is 3mm passes nozzle body 1, and the length of injection nozzle 3 is 6mm, and the one end being passed by injection nozzle 3 on nozzle body 1 is the sphere of radius 23mm.
3 direction from feed end to injection nozzle, feed pipe 2 gradually closings, change gently, and the flow resistance of melt in feed pipe 2 is little, and 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.
