Refer to Fig. 5, except the oil cylinder post 61 that figure 5 illustrates the structural system of the die mechanism 6 except having mentioned above and heating cylinder 62, the left mould bases 9a(that also show the hollow plastic blow molding machine belonging to known technology category also can claim left template), right mould bases 9b(also can claim right template), left mould 10a(also can claim left half module) and right mould 10b(also can claim right half module), left mould 10a is arranged on left mould bases 9a, and right mould 10b is arranged on right mould bases 9b.The shaping plastic melt base 20 being in molten condition of inflation that awaits coming from the runner exit 71 of foregoing plastics melt flow channel 7 enters left and right between mould 10a, 10b, left and right mould bases 9a, 9b in opposite directions displacement and drive left and right mould 10a, 10b to be in matched moulds state under shaping to plastic melt base 20 inflation by the inflation shaping mechanism (industry be accustomed to claim blow needle mechanism) of hollow plastic blow molding machine, obtain hollow plastic container after die sinking.
Applicant's composition graphs 1 to Fig. 5 sketches use of the present invention, when it is the hollow plastic container of 0.5 ㎜, 1 ㎜, 1.2 ㎜, 1.5 ㎜, 2 ㎜, 2.5 ㎜ or 3 ㎜ etc. that wall thickness will be produced, that is when producing when the hollow plastic container of arbitrary wall thickness of 0.5-3 ㎜ scope, so by the action of one group of elastic collar thixotroping device 5.Now to produce the hollow plastic container that wall thickness is 0.5 ㎜, the action of one group of elastic collar thixotroping device 5, fuel feed hole 531 oil-feed, pressure oil enters oil suction chamber 5412 through oil input channel 534, along with the pressure increase in oil suction chamber 5412, promote the direction displacement of piston body 554 to oil back chamber 5411, the fluid in oil back chamber 5411 is drawn through back oil road 524 and oil outlet 521.Because piston body 554 is integrally formed on cylinder piston rod 55, thus cylinder piston rod 55 is with piston body 554 synchronous shift, again because the position that slide block push rod 56 is corresponding to push rod connecting screw hole 5511 is connected with push rod connector 551, namely be connected with cylinder piston rod 55, thus along with cylinder piston rod 55 stretching to the direction of slide block chamber 411 to band movable slider push rod 56 during the direction displacement of elastic collar pressure ring 54 corresponding to the rod aperture 511 be opened on oil cylinder fixing base 51 in jogger hole 4111, also because slide block 561 is fixed on slide block push rod 56, thus along with slide block push rod 56 is together with the stretching, extension of slide block 561 to slide block chamber 411, the bottom (outer wall of elastic collar 3) of elastic collar 3 is spreaded to by slide block 561, elastic deformation is there is in the bottom of elastic collar 3 towards the direction of core rod 1, make the narrowed width of aforesaid plastic melt runner 7, until make the width of runner exit 71 meet the technological requirement of 0.5 ㎜.By online assignment personnel, adjusting nut 59 is operated (passing through spanner) simultaneously, make aforesaid gap L reach 0.5 ㎜, and locked by lock nut 591.
After above-mentioned adjustment action completes, the plastic melt heated by heating cylinder 62 enters plastic melt runner 7, draw through runner exit 71 again, plastic melt base 20 through runner exit 71 extraction enters and is in the left and right between mould 10a, 10b of die opening state, under matched moulds state, mold the hollow plastic container that wall thickness is 0.5 ㎜ above by the inflation shaping mechanism inflation mentioned.
Under aforesaid state, when to blow be greater than 0.5 ㎜ and be less than the hollow plastic container of 0.3 ㎜ wall thickness time, such as when the hollow plastic container of 2 ㎜ wall thickness will be blown, so aforesaid oil outlet 521 develops into fuel feed hole, and aforesaid fuel feed hole 531 develops into oil outlet, piston body 554 is to the direction displacement of oil suction chamber 5412, until the width of runner exit 71 becomes 2 ㎜ from 0.5 original ㎜, aforesaid gap L is with example.
A kind of mode is in addition: can enable certain the several elastic collar thixotroping device in one group of elastic collar thixotroping device 5 selectively, such as, enable four in eight, so just can meet the hollow plastic container that the wall thickness produced on same cross section is different.Because this mechanism of action is similar to the CN102145540B mentioned in applicant's superincumbent background technology hurdle and can see the description last page final stage of this CN102145540B, thus applicant repeats no more.
In sum, technical scheme provided by the invention overcomes the deficiency in prior art, successfully completes invention task, has cashed the technique effect referred in the superincumbent technique effect hurdle of applicant faithfully, a ultimate attainment technical scheme of can yet be regarded as.
