Abstract
The utility model provides a kind of blow needle, it is therefore an objective to the problem of avoiding causing bottle bucket wall unevenness even when carrying out and blowing in mould.Including blow needle body；The blow needle body is provided with inlet end and outlet side；The outlet side is provided with venthole；Especially, the venthole at least 30 and it is divided at least 3 groups；It is circumferentially evenly distributed to belong to same group of venthole；Angle between its axially bored line of venthole of difference group and the axis of blow needle body is different.Blow needle of the present utility model has advantages below：The all directions that high pressure draught can be dispersed to inside bottle bucket so that the wall thickness of the bottle bucket produced is more uniformly distributed, and lifts the bulk strength of product.
Description
Technical field
It the utility model is related to a kind of with blow needle used during blowing process production bottle bucket in mould.
Background technology
Existing bucket used for canned water, hereinafter referred to as bucket, produced by blowing process in mould.In one of which mould
The production process of blowing process substantially is as follows：From the expects pipe of discharging opening extrusion molten condition, expects pipe grows from up to down, then left
It is the inner chamber of predetermined shape inside it after mould and right mould matched moulds, left mould and right mould matched moulds, expects pipe is clipped in the middle by left mould and right mould,
Hereafter the blow needle in discharging opening center is in material treacheal gas insufflation, is allowed expects pipe to expand and is finally bonded the inner chamber of mould, left mould and the right side
Mould is the mould with liquid cold passage, will be cooled and shape after expects pipe fitting left mould and right mould.Hereafter left mould and right mould separation,
Bucket semi-finished product can be removed.
The existing blow needle for blowing process production bottle bucket in mould, its structure is only that a root bottom part is provided with circular open
Pipe fitting.Such blow needle can cause high pressure draught to fling the position at the close bucket bottom inside bottle bucket in air blowing process, and cause
The thickness at the position is relatively thin compared with the thickness at other positions.This is not the desired effects of design, is then needed to existing
The structure of some blow needles is improved.
The content of the invention
The utility model provides a kind of blow needle, it is therefore an objective to avoids causing bottle bucket wall unevenness even when carrying out and blowing in mould
Problem.
Using following technical scheme：
Blow needle, including blow needle body；The blow needle body is provided with inlet end and outlet side；The outlet side is provided with outlet
Hole；Especially, the venthole at least 30 and it is divided at least 3 groups；It is circumferentially evenly distributed to belong to same group of venthole；
Angle between its axially bored line of venthole of difference group and the axis of blow needle body is different.
Structural principle of the present utility model is as follows：Venthole is set by packet and subangle so that high pressure draught
Blow to each position of bottle bucket inwall with being more uniformly distributed after blow needle sprays, so as to solve the problems, such as bottle bucket wall unevenness.
The angle is preferably between 0 ° to 60 °.
The outline of the outlet side is preferably hemispherical；It is arranged on the venthole of outlet side its hole exits and is distributed in hemisphere
On the outlet end surfaces of shape.
If it should be noted that there was only 1 venthole in one group, " venthole circumferentially arranges " should be appreciated that
Overlapped for the axially bored line of the venthole with the axis of blow needle body.
Blow needle of the present utility model has advantages below：The all directions that high pressure draught can be dispersed to inside bottle bucket, make
The wall thickness for obtaining produced bottle bucket is more uniformly distributed, and lifts the bulk strength of product.

Embodiment
The utility model content is described further with reference to embodiment.
As shown in figure 1, the blow needle of the present embodiment includes：Blow needle body 1；Blow needle body 1 is provided with inlet end 11 and outlet side
12。
Wherein, the outline of outlet side 12 is hemispherical to be arranged on the venthole 13 of outlet side 12 its hole exits point
Cloth is on hemispheric outlet end surfaces.In the present embodiment, 74 ventholes 13 are provided with outlet side 12, these ventholes are determined
Justice is divided into 6 groups, and first group 101 is wrapped including 25, second group 102 including 18, the 3rd group 103 including 16, the 4th group 104
Include 10, the 5th group 105 includes 1 including 4, the 6th group 106.
As shown in Fig. 2 the venthole for belonging to same group is circumferentially evenly distributed, it is concentrically between different groups
Arrangement.Angle between its axially bored line of venthole of difference group and the axis C of blow needle body is mutually different.This implementation
In example, the angle belonged between its axially bored line of first group of venthole and the axis C of blow needle body is 56 °；Belong to second group
Its axially bored line of venthole and blow needle body axis C between angle be 38 °；Belong to the 3rd group of venthole its axially bored line
Angle between the axis C of blow needle body is 18 °；Belong to the axis of its axially bored line of the 4th group of venthole and blow needle body
Angle between line C is 15 °；The angle belonged between its axially bored line of the 5th group of venthole and the axis C of blow needle body is
8°；The angle belonged between its axially bored line of the 6th group of venthole and the axis C of blow needle body is 0 °
There was only 1 venthole in 6th group, then the hole of the venthole is construed as to " venthole circumferentially arranges "
Axis overlaps with the axis of blow needle body.
The blow needle of the present embodiment sets venthole by packet and subangle so that high pressure draught is after blow needle sprays
Blow to each position of bottle bucket inwall with being more uniformly distributed, so as to solve the problems, such as bottle bucket wall unevenness.
What this specification was enumerated is only better embodiment of the present utility model, it is all in operation principle of the present utility model and
The equivalent technologies conversion done under thinking, is accordingly to be regarded as the scope of protection of the utility model.
