Detailed description of the invention
The most i.e. coordinate graphic act with the present invention one preferred embodiment, be described as follows.
First, refer to shown in Fig. 1 to Fig. 4, have open provided in a preferred embodiment of the present invention
The material feeding extremity piece 10 of runner, consists predominantly of a body 20 and a runner 30.
This body 20 is the most plate-shaped, has the First portion 21 and one second portion 22 the most repeatedly connect；
Wherein, this First portion 21 has the tabular First body 211 of a suitable thickness, and a section is generally in tetragon
Strip headwall 212, be based on the side plate end of this First body 211 with major axis side；This second
Portion 22 is the most plate-shaped, it is possible to bottom side end face sticks on the upside end face of this First body 211.
This runner 30 is located in this body 20, in order to form the passage for macromolecule raw material flowing, has one
Influent stream portion 31, one goes out stream portion 32 and between this influent stream portion 31 and this flow portion 33 going out between stream portion 32,
Wherein:
This influent stream portion 31, in poroid, provides on this headwall 212, and in the another side of this headwall 212 major axis
Form aperture；
This goes out stream portion 32 also in poroid, provides on this First body 211, and at this First body 211
Downside end face form aperture；
This flow portion 33 is then in the channel-shaped of top side transmission, recessed on the upside end face of this First body 211,
Go out stream portion 32 with this connecting this influent stream portion 31, and make the notch of top side transmission must be by being repeatedly connected to this First
This second portion 22 on body 211 is closed, and to form the flow channel that week side is closing, guides high score
The flowing of sub-raw material.
The material feeding extremity piece 10 of the open runner of this tool in use, in order at known Jet forming machine with known
Form the runner for melted macromolecule flowing between mould, make if the macromolecule raw material such as rubber, plastic cement is via
After knowing that Jet forming machine institute heat is melted, the stream that can be formed via the material feeding extremity piece 10 of the open runner of this tool
Road, is injected into mould inside, with the high molecular molded processing that carries out.
More specifically, the material feeding extremity piece 10 of the open runner of this tool can be as shown in Fig. 5 to Fig. 8, should
In the known single step form ejection formation processing unit (plant) 40 being made up of single ejaculator and single mould station,
And be connected to this single step form ejection formation with the First portion 21 of the material feeding extremity piece 10 of the open runner of this tool and add
Frock is put on an ejaculator 41 of 40, and makes this influent stream portion 31 coaxially connect with the discharging opening of this ejaculator 41
Logical, and, make this second portion 22 amplexiform in this single step form ejection formation processing unit (plant) 40 with top side end face
One in order to implement to open mould assembling action and hold under the arm on the upper bolster 431 of mold mechanism 43 to a mould 42, and can be with
This holds the running of mold mechanism 43 under the arm and displacement.
Accordingly, this First portion 21 with the motion of this ejaculator 41, and can stretch into and between this mould 42
And between this upper bolster 431, waiting, this holds under the arm while mold mechanism 43 completes mould assembling action to this mould 42, makes
This goes out stream portion 32 and connects with the sprue on this mould, simultaneously with this second portion 22 be the most repeatedly connected to this
On one body 211, with the notch of this flow portion 33 of blocking, macromolecule raw material is made to flow through this from this discharging opening
Runner 30, when injecting this mould inside via the sprue of this mould, it can be ensured that raw material not seepage flow, overflow
Outside this runner 30.
Followed by, after completing material feeding program, this second portion 22 with this hold under the arm mold mechanism 43 die sinking action and
Away from this this First body 211, with the notch of this flow portion 33 open, hereat, it is positioned in this runner 30
Macromolecule raw material, easily can take out via the open notch of this flow portion 33, and can avoid fracture
Deng the inconvenient situation generation of increasing cleaning demand on foot, and can be beneficial to expect clearly the carrying out of procedure operation.
Furthermore, the material feeding extremity piece 10 of the open runner of this tool can also as be applied to single step form ejection formation
As processing unit (plant), it is applied to be made up of with most mould stations 52 single or minority ejaculator 51
Know in linear multimode standing posture ejection formation processing unit (plant) 50, as shown in Figures 9 to 11 as, this linear multimode
Standing posture ejection formation processing unit (plant) 50, the composition of visual actual injection raw material is different, and can optionally by
Single or minority ejaculator 51 is located on a linearly extended linear track 53 altogether, in order to so that should or respectively should
Ejaculator 51 can on this linear track 53 shift reciprocately, and can respectively with along this linear track extension side
It is located at respectively this mould station 52 of this track 53 side the most adjacent, in order to by this or each this ejaculator to sequentially row
51 by macromolecule raw material via the material feeding extremity piece 10 of the open runner of this tool inject in corresponding mould station 52 single
Or in single or many digital-to-analogues room of majority mould.
But for reducing the cost arranged, the material feeding extremity piece 10 of the open runner of this tool is being applied to linear multimode
During standing posture ejection formation processing unit (plant) 50, in addition to this First portion 21 still maintains and is incorporated on ejaculator 51,
This second portion 22 the most directly stacks in this First portion 21, and does not adopt and take off shown in Fig. 5 to Fig. 8 as front
As be incorporated into and hold under the arm in mold mechanism, accordingly, then this second portion 22 can be set with this First portion 21
Ejaculator 51, and at this track 53 top offset, and can by each mould station 52 entire be molded into material time profit
With, and without being respectively provided with independent second portion on each mould station, use the quantity reducing component, with joint
Cost-saving.
