Description
Technical field
The present invention relates to die casting machine, injection machine matched moulds clamping mechanism technology, is a kind of vertical compression type mould-locking column rack, can be applicable to die casting machine, injection machine.
Background technology
In the forming materials manufacturing industry, be used for the die casting machine of specialty metal moulding, its structure generally is made up of the matched moulds clamping mechanism, injection mechanism, hydraulic transmission element, the electric controling element that are installed on the support.It is one of mechanism main in the die casting machine that the matched moulds clamping mechanism also can be called mould-locking column rack; it comprises a plate (solid plate), middle plate (moving platen), tailgate, four big thick sticks, promote in plate shift to firm and hard now be separately fixed in the hydraulic pressure of dynamic and static pattern matched moulds locked mode on plate and the plate and mechanical transmission mechanism, mould adjusting mechanism, four big thick sticks are the framework of rectangle with a plate, middle plate, the tailgate cross section that forms that is together in series.The size of the clamp force of mould-locking column rack, locked mode rigidity, locked mode equilibrium of forces and stable, motion of mechanism precision etc. are directly connected to the quality of product.
At present, mould-locking column rack generally has two big classes:
One class is a hydraulic pressure crank connecting rod formula, its folding mould by be fixed in oil cylinder piston bar behind the tailgate promote by the machine hinge body in plate (moving platen) motion realize.After the machine hinge was stretched, the toggle self-locking was mode-lock status.Mould adjusting mechanism is used for when changing the mould of different-thickness, the distance in the adjustment between a plate and the plate.Mould adjusting mechanism is installed on the tailgate; the a pair of reduction gearing transmission of fluid motor-driven; wherein gear wheel is engaged in the pinion on the adjusting nut that is threaded with four big thick sticks again simultaneously; the rotation driven in synchronism tailgate of adjusting nut, middle plate move along support, the adjustment of distance between a plate and the plate in the realization.The advantage of this mould-locking column rack embodies a concentrated reflection of on the machine hinge structure, and the form with the folding of small oil tank driving machine hinge is converted to mechanical motion, has realized mechanical self-latching, the locked mode good rigidly.Shortcoming is machine hinge body physical dimension, technological standards, Geometrical Tolerance Principle strictness, difficult control (particularly macrostructure type) of precision processing, and adjust, the location is inconvenient, often causes machine hinge clamp force imbalance, machine hinge transmission rotary part frictional force is big, bearing wear is serious, relative accuracy descends, and moving platen is poor with a plate depth of parallelism, and the die joint gap is inconsistent all around to cause mould, even the mode transfer difficulty, maintenance and repair cost height.And each slip of machine hinge, rotary part are that open type is lubricated, cause serious environmental issue such as inevitable energy waste, environmental pollution.
Another kind of is direct press type, by the reciprocating motion of oil cylinder piston bar, and plate motion in the promotion, realization is closed, die sinking, locked mode.Through updating, initial vertical compression type mould-locking column rack is plate motion in being promoted by a large scale oil cylinder that is fixed on tailgate to vertical compression type mould-locking column rack, and realization is closed, die sinking, locked mode.Have the mold thickness compatibility, do not need mode transfer, the advantage of each big thick stick clamp force balance, exist since piston rod need contain in the effective area of plate (moving platen), cause oil cylinder and oil supply system huge, oil cylinder stroke is long, volume is big, causes the problem of locked mode poor rigidity.A kind of on above-mentioned vertical compression type mould-locking column rack basis, carried out improved vertical compression type mould-locking column rack be set up two symmetries be fixed on be used on the tailgate to close, the independent oil cylinder of die sinking, locked mode is little with the volume of oil cylinder like this, the Mode-locking oil cylinder system is simplified greatly.The locked mode principle is similar to injector for medical purpose, drives the oil suction of Mode-locking oil cylinder piston when folding mould oil cylinder matched moulds is worked, and after matched moulds finished, fast row closed, and the locked mode oil piping system begins to Mode-locking oil cylinder oil-filled, realizes the locked mode function.Its advantage is that oil supply system is simplified because the increase of oil cylinder quantity has reduced the oil cylinder body volume.Shortcoming is owing to do not break away from the design concept of hydraulic press, certainly exists the eccentric allowable value of mould, when surpassing mould off-centre allowable value, might interrupt middle plate (moving platen), the locked mode poor rigidity is made the large scale computer difficulty, the more existing toggle formula of volume is huge, and quality increases.The follow-on direct pressure of another kind mechanism has saved tailgate; Mode-locking oil cylinder is 4 small-sized oil cylinders; be distributed in respectively on 4 angles of middle plate (moving platen), piston rod developed into nested structure directly be set on the big thick stick, on the middle plate (moving platen) the open-close type flashboard is housed.The folding mould is by independently servo-cylinder realization, and behind plate (moving platen) matched moulds, open type flashboard and big thick stick helicitic texture interlock close a floodgate and block screw thread in servo-cylinder drives, and 4 Mode-locking oil cylinder piston rods withstand flashboard big thick stick elongation is realized locked mode.Its advantage is that original long moving lock mould oil cylinder is optimized for ultrathin oil cylinder, and the Mode-locking oil cylinder piston stroke is to change by the threaded engagement position on the big thick stick, and the volume of oil cylinder working chamber changes with the remainder of mold thickness with respect to big thick stick pitch merchant.Four big thick stick force balances.Shortcoming is that structure is huge on the moving platen, and quality is big, for guaranteeing movement velocity, the kinematic accuracy of moving platen, has set up guiders such as expensive servo valve control system and rolling guide, and the complete machine cost is increased.
Above-mentioned vertical compression type mould-locking column rack is applied in and also has a common defective on the die casting machine, exactly in the time can't resisting injection mechanism in varying degrees and shoot material because the two-speed of injection punch head produces instantaneous impact to mould-locking column rack." two-speed shoots material " be meant when injection process the drift initial stage of motion forward be one section at a slow speed, when at a slow speed later energy-storing device fast-discharge valve moment open, the highly pressurised liquid in the energy-storing device with the speed of 6 to 8 meters of per seconds with the drift forward impelling.Therefore, in the injection process, the die casting machine mould not only is subjected to the static pressure effect, also is subjected to the percussion of two-speed.The expansive force that temporary impact produces is passed to Mode-locking oil cylinder by mould.Under this percussion, the instantaneous change of Mode-locking oil cylinder oil pocket volume is big, and main is to contain gas in the oil pressure medium, and oil pressure medium decrement is strengthened, and clamp force descends naturally thus, causes mould and flies material.
