Detailed description of the invention
Hereby namely coordinate graphic act with the present invention one preferred embodiment, be described as follows.
First, refer to shown in Fig. 1 to Fig. 4, in a preferred embodiment of the present invention the material feeding extremity piece 10 of the open runner of tool is provided, consist predominantly of a body 20 and a runner 30.
This body 20 generally in tabular, has the First portion 21 and one second portion 22 that repeatedly connect each other; Wherein, this First portion 21 has the strip headwall 212 of tabular First body 211, section generally in quadrangle of a suitable thickness, is based on the side plate end of this First body 211 with major axis side; This second portion 22 also in tabular, and can stick on the upside end face of this First body 211 by bottom side end face.
This runner 30 is located in this body 20, in order to form the passage for macromolecule raw material flowing, has an influent stream portion 31, and goes out stream portion 32 and and go out the flow portion 33 between stream portion 32 between this influent stream portion 31 and this, wherein:
This influent stream portion 31, in poroid, provides on this headwall 212, and in the formation aperture, another side of this headwall 212 major axis;
This goes out stream portion 32 also in poroid, provides on this First body 211, and forms aperture at the downside end face of this First body 211;
The channel-shaped of this flow portion 33 in top side transmission, recessed on the upside end face of this First body 211, stream portion 32 is gone out with this to be communicated with this influent stream portion 31, and make the notch of top side transmission must by this second portion 22 be repeatedly connected on this First body 211 close, be closed flow channel to form all sides, the flowing of guiding macromolecule raw material.
The material feeding extremity piece 10 of the open runner of this tool in use, in order to form the runner flowed for melting macromolecule between known Jet forming machine and known mould, make if the macromolecule raw material such as rubber, plastic cement is after melting via known Jet forming machine institute heat, the runner that can be formed via the material feeding extremity piece 10 of the open runner of this tool, be injected into mould inside, with the high molecular molded and shaped processing that carries out.
More particularly, the material feeding extremity piece 10 of the open runner of this tool can as shown in Fig. 5 to Fig. 8, be applied in the known single step form ejection formation processing unit (plant) 40 be made up of single ejaculator and single mould station, and be connected on an ejaculator 41 of this single step form ejection formation processing unit (plant) 40 with the First portion 21 of the material feeding extremity piece 10 of the open runner of this tool, and make the discharging opening coaxial communication of this influent stream portion 31 and this ejaculator 41, and, make this second portion 22 with top side end face amplexiform in this single step form ejection formation processing unit (plant) 40 one in order to one mould 42 implement open on the upper bolster 431 holding mold mechanism 43 under the arm of mould assembling action, and the running of mold mechanism 43 can be held under the arm and displacement with this.
Accordingly; this First portion 21 can with the motion of this ejaculator 41; and to stretch into and between this mould 42 and this upper bolster 431; waiting, this holds under the arm while mold mechanism 43 completes mould assembling action to this mould 42; make this go out stream portion 32 to be communicated with the sprue on this mould; closely repeatedly be connected on this First body 211 with this second portion 22 simultaneously; the notch of this flow portion 33 is closed with resistance; macromolecule raw material is made to flow through this runner 30 from this discharging opening; when sprue via this mould injects this mould inside, can guarantee raw material not seepage flow, overflow to outside this runner 30.
Then; 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, be arranged in the macromolecule raw material of this runner 30, easily can take out via the open notch of this flow portion 33; and the inconvenient situation of apprentice's increasing cleaning demands such as rupturing can be avoided to produce, and the carrying out of expecting clearly procedure operation can be beneficial to.
Moreover, the material feeding extremity piece 10 of the open runner of this tool also can as be applied to as single step form ejection formation processing unit (plant), be applied in the known linear multimode standing posture ejection formation processing unit (plant) 50 be made up of the ejaculator 51 of single or minority and most mould stations 52, as shown in Figures 9 to 11, this linear multimode standing posture ejection formation processing unit (plant) 50, the composition of visual reality injection raw material is different, and can optionally ejaculator 51 that is single or minority be located on a linearly extended linear track 53 altogether, in order to do with make this or respectively this ejaculator 51 can on this linear track 53 shift reciprocately, and can respectively with sequentially arrange respectively this mould station 52 being located at this track 53 side along this linear track bearing of trend sequentially adjacent, in order to do with by this or respectively this ejaculator 51 macromolecule raw material injected single or most mould room of the single or most mould in corresponding mould station 52 via the material feeding extremity piece 10 of the open runner of this tool.
But for reducing the cost arranged, the material feeding extremity piece 10 of the open runner of this tool is when being applied to linear multimode standing posture ejection formation processing unit (plant) 50, except this First portion 21 still maintains, to be incorporated into ejaculator 51 upper outside, this 22, second portion directly stacks in this First portion 21, and do not adopt and hold under the arm in mold mechanism as being incorporated into as front taking off shown in Fig. 5 to Fig. 8, accordingly, the ejaculator 51 that then this second portion 22 and this First portion 21 can be set, and at this track 53 top offset, and can by each mould station 52 when entire mould material feeding utilize, and without the need to all arranging independently second portion on each mould station, use the quantity reducing component, to save cost.
