Description
Technical field
The utility model is related to a kind of mold design, more particularly to a kind of high accuracy guarantee type for long narrow hollow pipe fitting
Enter glue nozzle.
Background technology
Shooting Technique is a kind of selection process that can meet various nonstandard shaped piece processings, cut compared to tradition,
Milling Machining operating type is rushed, with one-shot forming, the significant advantage being produced on a large scale, however, due to the shape of injecting products
Diversity, injection-molded work 1 especially as depicted in figs. 1 and 2, its body shape is in narrow long type hollow pipe, and one end is closed and another
End is provided with the pedestal 11 of tube wall thickening, is one section of long narrow hollow pipe 12 outside pedestal 11, and it is internal with coaxial with hollow pipe
Concentric cylindrical cavity 13.
It is seen that, so-called its length of long narrow hollow pipe fitting often reaches more than 20cm, and external diameter is generally only length
1/10th is even more small, and such pipe fitting tube wall often than relatively thin, typically only 2mm or so.As can be seen here, for injection
Be molded such pipe fitting, it is desirable to produce in batches and high accuracy keep specifications parameter, traditional technique be it is difficult to realize, on the one hand by
Avoid producing into glue point in the requirement of pipe fitting surfaces externally and internally, the one end of pipe fitting can only be concentrated on.And prolonging with injection distance
Stretch, what the cooling and solidifying of sizing material can influence product back segment smoothly enters glue, so as to cause the scarce material of pipe fitting end, produces defective products.
The content of the invention
In view of the defect that above-mentioned prior art is present, the purpose of this utility model is to propose a kind of long narrow hollow pipe fitting injection
The glue that enters of mould improves nozzle.
The purpose of this utility model will be achieved by the following technical programs：A kind of long narrow hollow pipe fitting injection mold
Entering glue improves nozzle, between the composition surface of injection mold upper die and lower die, correspondence is provided between the upper die and lower die narrow
The injection cavity volume of elongated hollow tube part, injection cavity volume is axially parallel to composition surface, it is characterised in that：It is described enter glue improve nozzle have
Along the circumferentially equally distributed two or more spout in long narrow hollow pipe fitting one end, and spout plastic emitting direction and long narrow hollow pipe fitting
Axial phase deflection.
Further, it is described enter glue improve nozzle from root into Y-shaped branch, and branches end the spout long narrow sky of correspondence
The relative tube wall of heart pipe fitting.
Further, it is described enter glue improve first branch of the nozzle from root into parallel shape, and two in place of die cavity is closed on
It is secondary to be provided with Y-shaped branch, the tube wall of the spout long narrow hollow pipe fitting of correspondence of each branches end.
Further, the injection cavity volume has from the die bar for entering glue end one elongation moulding, and die bar and injection
Cavity volume coaxial concentric.
Further, the die bar surface smooth pieces, and the inner surface of the injection cavity volume to be set to texture coarse
Face.
Using it is of the present utility model enter glue improve nozzle, its advantage is embodied in：The special form of injecting products can be met
Shape and required precision, realize that helical form enters glue and multiply is converged by the nozzle, effectively increase the confession glue of injecting products end
Surplus so that long narrow hollow pipe fitting can meet many precision such as concentricity, perpendicularity and surface roughness after shaping will
Ask.
Brief description of the drawings

Specific embodiment
Hereinafter just accompanying drawing in conjunction with the embodiments, is described in further detail to specific embodiment of the present utility model, so that this
Utility model technical scheme is more readily understood, grasps.
It is new to processing such length, the hollow pipe fitting mould of thin-walled and technologic difficulty, this practicality for prior art
Type designer is researched and developed through creativeness and proposes one kind and enters glue improvement nozzle, and injection-molded finished structural strength and precision is lifted with this
Quality.
As shown in Figures 3 to 5, the glue that enters of this kind of long narrow hollow pipe fitting injection mold improves nozzle located at mould on injection mold
Between 21 and the composition surface of lower mould 22, the injection cavity volume 23 of the long narrow hollow pipe fitting of correspondence is provided with this between mould 21 and lower mould 22,
Injection cavity volume is axially parallel to composition surface.Other structures configuration on injection mold is essential and sufficiently complex but non-
The design emphasis, therefore graphical simplicity, explanation are omitted.Only the core of the design be embodied in this enter glue improve nozzle 25 have along long narrow
The circumferentially equally distributed two or more spout in hollow pipe fitting one end, and plastic emitting direction and the long narrow hollow pipe fitting of spout axial phase
Deflection（As shown in Figure 5）.
As a kind of embodiment, this enter glue improve nozzle 25 can from root into Y-shaped branch, and branches end spout
The relative tube wall of the long narrow hollow pipe fitting of correspondence.Product has diameter to enter glue point to two of two ends i.e. under the embodiment, due to spout
The obliquity in direction, can converge along certain oblique charging and gradually after injection cavity volume charging.So share and being initially injected into
The resistance that sizing material gradually solidifies, by the disturbance effective guarantee injecting glue amount of product distal end for entering glue.
Used as preferred another embodiment of this creation, as shown in Figure 4 and Figure 5, this enters glue improves nozzle from 261 one-tenth of root
First branch 262 of parallel shape, and the secondary stroke Y-shaped branch 263 in place of die cavity is closed on, and each branches end spout pair
Answer the tube wall of long narrow hollow pipe fitting.Ibid, can along certain oblique helical form charging and gradually so after injection cavity volume charging
Converge.Be conducive to ensureing the filling volume of product injection.
Additionally, the injection cavity volume 23 has from the die bar 24 for entering glue end one elongation moulding, and die bar 24 and injection
The coaxial concentric of cavity volume 23.Furthermore, for the different surface configuration of product, the surface smooth pieces of die bar 24, and injection cavity volume
23 inner surface is set to texture mat surface.If the surface of certain long narrow hollow pipe fitting is for two sides is smooth, two sides texture is coarse
Face or all kinds of surface details of other forms, also can carry out corresponding processing matching to the surface for being molded cavity volume.But normal conditions
Lower is to ensure to move back the smooth of mould, and the die bar is a kind of normality Sexual behavior mode for smooth surface.
Using it is of the present utility model enter glue improve nozzle, its advantage is embodied in：The special form of injecting products can be met
Shape and required precision, realize that helical form enters glue and multiply is converged by the nozzle, effectively increase the confession glue of injecting products end
Surplus so that long narrow hollow pipe fitting can meet many precision such as concentricity, perpendicularity and surface roughness after shaping will
Ask.
The utility model still has numerous embodiments, all use equivalents or equivalent transformation and all technologies for being formed
Scheme, all falls within protection domain of the present utility model.
