Abstract
In order to solve the technical problem that nozzle positioning is inaccurate in the prior art, the utility model provides a kind of dock nozzle location structure, include the nozzle one mounted on cover half and the nozzle two mounted on dynamic model, it is arranged with pilot bushing one outside nozzle one, it is arranged with pilot bushing two outside nozzle two, the mouth of a river shape of pilot bushing one and pilot bushing two is spherical shape.One end that pilot bushing one corresponds to pilot bushing two is arranged there are one the boss of cone, and pilot bushing two corresponds to and inserts with the matched groove of boss, boss there are one settings at boss and in a groove positions nozzle one and nozzle two；After mold clamping, boss takes the lead in inserting and in a groove positions nozzle one and nozzle two, effectively prevents the generation that plastic is cracked and hot mouth is to top crack conditions.
Description
Technical field
The utility model is related to hot runner system technical fields, more particularly to dock nozzle location structure.
Background technology
One of hot flow path major function is that the plastic melt in hot flow path is entire in the injection of moulding cyclc, pressurize and cooling
Stage keeps correctly processing to stablize, and to reach no cold water outlet, reduces secondary operation, shortens injection cycle, improves product one
Cause property is realized and is produced in enormous quantities, and production cost is reduced.In Hot runner Technology field, needle valve type hot runner is to save material, plastic
Surface aesthetic, while the advantages that internal soundness is close, intensity is high and being widely used.With the continuous development of Hot runner Technology,
Needle valve type hot runner system has been widely used in injection molding process.
Grafting formula hot runner system can generally be used for the molding of special plastic, be provided in fixed half and moving half opposite
Nozzle, after mold clamping, the hot mouth in nozzle, which is ejected, injects molten plastic into cavity.If the hot mouth in fixed half and moving half does not have
There is alignment, then the plastic being molded then will appear cast gate crackle, there will be severe the case where hot mouth is broken, affect just
Often at production, and each time repair a die the time and cost it is all higher.
Utility model content
The purpose of this utility model is to overcome the inaccurate technical problems of the positioning of nozzle in the prior art.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
Dock nozzle location structure includes the nozzle one mounted on cover half and the nozzle two mounted on dynamic model, the spray
It is arranged with pilot bushing one outside mouth one, pilot bushing two is arranged with outside the nozzle two, is led described in the correspondence of the pilot bushing one
To the setting of one end of bushing two there are one the boss of cone, the pilot bushing two correspond at the boss setting there are one with
The matched groove of boss, the boss are inserted in the groove and position nozzle one and nozzle two；The groove
Bottom is provided with the annular groove that a circle depth is 0.5mm.
Further, after the boss injects in the groove, the shoulder of the pilot bushing one is served as a contrast with the guiding
The gap of a 0.5mm width is formed between set two.
Further, the mouth of a river shape of the pilot bushing one and pilot bushing two is spherical shape.
The utility model has the beneficial effects that：1. after mold clamping, boss takes the lead in inserting in a groove by nozzle one and nozzle
Two are positioned, and the generation that plastic is cracked and hot mouth is to top crack conditions is effectively prevented；2. can be sent out after nozzle is heated
Raw expansion, pilot bushing is no exception, and the setting of annular groove can prevent two pilot bushings to be adhered because of expansion.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.
Fig. 1 is the sectional view of the dock nozzle disclosed in the present embodiment;
Fig. 2 is the sectional view of the pilot bushing two disclosed in the present embodiment.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Dock nozzle as shown in Figure 1 includes one A of nozzle mounted on cover half and two B of nozzle mounted on dynamic model, spray
It is arranged with pilot bushing 1 outside mouth one, pilot bushing 22, the water of pilot bushing one and pilot bushing two are arranged with outside nozzle two
Mouth-shaped is spherical shape.Referring to Fig. 1 and 2, there are one the boss of cone for one end setting of the correspondence pilot bushing two of pilot bushing one
3, pilot bushing two is corresponded to and is inserted nozzle one and spray in a groove with the matched groove 4 of boss, boss there are one settings at boss
Mouth two is positioned；After mold clamping, boss takes the lead in inserting and in a groove positions nozzle one and nozzle two, is effectively prevented
Plastic is cracked and hot mouth is to pushing up the generations of crack conditions.
The bottom of groove is provided with the annular groove 5 that a circle depth is 0.5mm, after boss injects in groove, pilot bushing one
The gap 6 of a 0.5mm width is formed between shoulder and pilot bushing two.It can be expanded after nozzle is heated, pilot bushing
Unexceptional, the setting in annular groove and gap can prevent two pilot bushings to be adhered because of expansion, ensure that the normal production of mold.
Various modifications to these embodiments will be apparent to those skilled in the art, herein
Defined General Principle can be real in other embodiments without departing from the spirit or scope of the present utility model
It is existing.Therefore, the utility model is not intended to be limited to the embodiments shown herein, and be to fit to it is disclosed herein
Principle and the consistent widest range of features of novelty.
Claims (3)
