Description
Technical field
The present invention relates to the resetting-mechanism of metal die-casting mold and plastic injection mould, is that one first resets mold mechanism.
Background technology
After metal die-casting mold and the plastic injection mould demoulding, in order to avoid ejecting mechanism and other part interfere, the device used or mechanism make mould emptier reset prior to other part, and this mechanism is reposition first.At present, the reposition first that metal die-casting mold and plastic injection mould use has: 1. spring reposition first, and it utilizes the restoring force of Compress Spring that ejecting mechanism is resetted.This mechanism is that spring is arranged between ejector pin retaining plate and gripper shoe, though this mechanism is simple, install easily manufactured, but there is spring fatigue creep properties, thus produce the phenomenon of timeliness change and the inefficacy of high temperature lower spring, so the homing action of spring reposition first is unreliable, security is poor.2. plug bush type reposition first, it is arranged on mould inside, the release link of this reposition first, sleeve and reset top cylinder are rigid structure, and in action is carried out, do not have elastic deformation and relaxation, whole course of action precision is high, the resetting-mechanism life-span is also high, but this mechanism structure is very complicated, and the manufacturing cycle is long, and cost is high, once damage, maintenance difficult.3. slide block reposition first, it utilizes the inclined-plane being arranged on the tapered bar of stationary mould for mould one side to be moved in mould by slide block, its slide block is made to force liftout plate to retreat, complete the first reset ejecting part, but this mechanism slide block is easily stuck in T-shaped groove, once slide block is stuck, reposition first lost efficacy, and very easily caused ejecting mechanism and other part to collide.4. supporting rod type reposition first, it is in ejection process, and support bar moves forward, promote push pedal, goods are ejected, meanwhile, due to the effect on actionless voussoir inclined-plane by push rod, support bar separately disengages with push pedal to both sides, at this moment goods are pushed out moving platen, make push rod first reset under the action of the spring, and this mechanism in use be unable to do without spring all the time, after spring failure, this mechanism is with regard to akinesia, and its structure resets, installs, debugs inconvenience simultaneously.In order to overcome the deficiency of above-mentioned reposition first, I am in conjunction with line design experiences for many years, and spy provides following a kind of mechanism to solve the problems referred to above.
Summary of the invention
The present invention is to provide one and first resets mold mechanism, it is that the fork (10) utilizing the slope driving being arranged on the tapered shaft (27) of stationary mould for mould one side to be arranged on dynamic model one side drives thimble backing plate (4) that its thimble (7) be arranged on thimble fixed head (6) is first resetted, and first to reset mold mechanism with the one avoiding thimble (7) and slide block (19) to collide and arrange.Its beneficial effect is: its structure is simple, install, debugging, easy to maintenance, its part is rigid structure entirely simultaneously, and in whole course of action, do not have elastic deformation and relaxation, operation precision is high, the resetting-mechanism life-span is high, its uniform force, highly sensitive, homing action is steady, safe and reliable, the homing action of ejecting mechanism and the homing action of side core-pulling mechanism divide two stages to carry out, and so there is no the possibility of at all mutually interfering, harmony is fabulous.Reset when simultaneously this reposition first is also of value to metal die-casting mold and plastic injection mould large pulling distance uses, and also can improve and use as two-step ejecting mechanism, easily realize standardization, seriation.One first resets mold mechanism, and after solving spring reposition first spring failure, resetting-mechanism action is unreliable, the problem of poor stability.Solve plug bush type reposition first complex structure, the manufacturing cycle is long, and cost is high, the problem of inconvenient maintenance.Solve slide block reposition first, slide block is easily stuck in T-slot, causes the irreducible problem of resetting-mechanism.Solve supporting rod type reposition first, complex structure, manufacture the problem of mold damage after inconvenience and spring failure.One first resets mold mechanism, it is characterized in that: it is made up of dynamic model and cover

Detailed description of the invention:
That one first resets mold mechanism as shown in the figure, this mechanism is to solve thimble (7) in ejecting mechanism after pushing out product (26), thimble (7) and angled-lift splits (19) in matched moulds process is avoided to collide, and first thimble (7) must be returned to matched moulds situation, then angled-lift splits (19) resets again, just can not collide and a kind of reposition first arranged.This reposition first adopts the tapered shaft (27) being arranged on cover half one side to force fork (10) to promote thimble fixed head (6) to drive thimble (7) first to reset, after thimble (7) resets to and ejects initial conditions, the Angle Pin (21) being arranged on cover half one side just inserts in the inclined hole of angled-lift splits (19) and forces angled-lift splits (19) to reset to matched moulds state, effectively like this achieves ejecting mechanism and side core pulling mechanism does not interfere the object reaching not mold damage.Its action is firm, and mould structure is simple, manufacture, install, debugging, easy to maintenance, and die cost is low, die life is long, and again because the reset components in resetting-mechanism is rigidity entirely, so there is no elastic deformation and relaxation, then mould reseting precision is high.One first its operating principle of reset mold mechanism is: after mold injects is shaping, open at the power bed die of injector or die casting machine, injector or die casting machine driven mold dynamic model part retreat, in This move process, goods (26) are pulled to dynamic model one side, continue die sinking, at this moment the Angle Pin (21) being arranged on cover half one side forces angled-lift splits (19) to do the action of mould right direction, in This move process, the convexconcave part of goods (26) from angled-lift splits (19) shaping deviate from, dynamic model part is moved after continuing, Angle Pin (21) is extracted from the inclined hole of angled-lift splits (19), simultaneously angled-lift splits (19) can not action again under the restriction of baffle plate (16), continue die sinking, after die sinking distance is greater than goods (26) and running gate system sprue solidifying material height, at this moment dynamic model part is moved after stopping, now injector or die casting machine push rod promotion thimble backing plate (4) drive the thimble (7) be arranged on thimble fixed head (6) outside goods (26) launch mode.After goods (26) launch mode is outer, during mould matched moulds, action contrary when injector or die casting machine driven mold dynamic model part do die sinking resets, in this reseting procedure, first the tapered shaft (27) being mounted in cover half one side contacts with fork (10), tapered shaft (27) drives fork (10) to move to mold center direction, the thimble (7) that in this course of action, fork (10) forces thimble backing plate (4) drive to be arranged on thimble fixed head (6) resets, after thimble (7) resets, injector or die casting machine drive dynamic model part to continue matched moulds, at this moment the Angle Pin (21) being arranged on cover half one side inserts in the inclined hole of angled-lift splits (19) and forces angled-lift splits (19) to move to mould left direction, after angled-lift splits (19) resets under the pressure of Angle Pin (21), then the baroclinic block (17) being arranged on stationary mould for mould one side is close to angled-lift splits (19), continue matched moulds, baroclinic block (17) locking angled-lift splits (19), when respectively open part completely closed after, injector or die casting machine just carry out the moulding by casting in next cycle.
