The specific embodiment

Embodiment, with reference to accompanying drawing, a kind of venous detaining needle single-blade die, comprise that fixation side fetching plate 1, fixation side template 2, movable side-draw pay plate 5, square iron 4, movable side template 3, eject push pedal 6, retaining plate 7, thimble 1, thimble 2 22, upper mold core fixed head 19, upper mold core 20, lower mold core fixed head 26, lower mold core 27, locating ring 16 and sprue bush 17, what it is characterized in that movable side template 3 toply inserts 36 with runner of pin fixed installation, and runner is inserted and 36 is provided with runner 39.Fixation side fetching plate 1 and six M12 bolts 42 of fixation side template 2 usefulness link together, and the center is fixed a locating ring 16 with M6 bolt 3 18, adorns a sprue bush 17 at locating ring 16 centers; Below fixation side template 2, fix a lock dog 10, fix a batter post 14, between batter post 14 and sprue bush 17, upper mold core fixed head 19 is housed, on upper mold core fixed head 19, be provided with 36 upper mold core 20 with M16 bolt 2 15 with M8 bolt 9.Two ends are fixed with limited post 13 on movable side template 3, the centre is fixed a runner with pin 25 and is inserted 36, runner insert 36 and limited post 13 between cavity block 30 and the slide block 11 that is fixed together with M4 bolt 28 is housed, slide block 11 is provided with slideway 12, slideway 12 flexibly connects with batter post 14, gating insert 29 is housed in the middle of the cavity block 30, correspondingly below gating insert 29 on movable side template 3, lower mold core fixed head 26 is being housed, be provided with lower mold core 27 in the above, corresponding with upper mold core 20; Fix a briquetting 37 with M6 bolt 5 33; With M6 bolt 6 34 fixedly connected sprue bush 17; Four guide pillars 32 are fixed in both sides on movable side template 3, being through in the guide pin bushing 41 on the movable side template 2 of guide pillar 32 upper end activities.Movable side-draw is paid between plate 5, square iron 4 and the movable side template 3 and is linked together with M6 bolt 1; Movable side-draw is paid the centre above the plate 5, is equipped with between the square iron 4 and ejects push pedal 6 and retaining plate 7; Be fixed with thimble 1 and thimble 2 22 on the retaining plate 7, thimble passes movable side template 3 up to lower mold core 27; Fix one in movable side template 3 centers with M6 bolt 4 24 and eject limiting plate 23.Be fixed with release link 31 on the limiting plate 23 ejecting, back-moving spring 38 be housed on the release link 31 and pass movable side template 3.Support column 35 is contained in movable side-draw and pays on the plate 5; On gating insert 29, be provided with runner 39; Be provided with cooling water channel 40 on fixation side template 2 and movable side template 3, cooling is the usefulness of single-blade sheet but.

With the disposable use venous detaining needle of this mould production and processing single-blade sheet process is like this, at first the mould under the matched moulds state is contained on the make-up machine.During matched moulds, the release system resets by release link 31 and back-moving spring 38, the make-up machine open-close system drives movable side template 3, square iron 4, movable side-draw is paid plate 5, thimble push pedal 6 and thimble fixed head 7 and moved forward, fashionable at gating insert 29 and 19 pairs of upper mold core fixed heads, upper mold core 20, lower mold core 27, cavity block 30, slide block 11 lock dog 10 with make mould become closed state under Angle Pin 14 drives.The coupling mechanism force locking that mould is provided by make-up machine matched moulds system in process of injection molding.The graininess plastics are sent to the barrel of heating from the hopper of injection machine, after the process heating was dissolved and is the shape that flows, under the promotion of injection moulding augering screw, the plastics of fusion were compressed and move forward, thereby nozzle, sprue bush 17, runner 39 by the barrel front end are injected into moulding in the closed die fast.Charge into the interior molten material of mould under the pressure that molding machine system provides, solidify the back die sinking through the water quench in the cooling water channel 40.During die sinking, make-up machine folding modular system drives that movable side-draw is paid plate 5, square iron 4, movable side template 3, thimble fixed head 7, thimble push pedal 6 retreats, cavity block 30, slide block 11 separate under the drive of Angle Pin 14, and behind the slow astern segment distance, the ejection system of make-up machine promotes to eject push pedal 6 and moves forward, under this effect, disposable use venous detaining needle single-blade sheet comes off from mould, finishes shot production process.This mould inserts 36 by having increased a runner, has improved complicated in the past structure, has realized multi-cavity mold.
