Technical field
The present invention relates to a kind of back cooling process of semi-finished that after from the open half module of injection machine, taking out semi-finished product, is used for, wherein also be under the hot state semi-finished product by withdrawing device by take out in the open mould and in the controllable stage by cooling off behind the water-cooled coolant jacket, comprise the phase I, add next injection cycle of carrying out interior cooling by cooling pin during this period, also comprise second stage, this stage is many times of injection cycle time.The invention still further relates to and a kind ofly after from the open half module of injection machine, taking out semi-finished product, be used for the half-finished device of back cooling by the water-cooled coolant jacket of withdrawing device, this device has auxiliary member and unloads from part mould in order to the semi-finished product that will partly solidify and cool off the semi-finished product that take out in the station and by the semi-finished product in the cooling device of water-cooled coolant jacket cooling back, also has cooling pin, wherein take out the withdrawing device that the station has the coolant jacket that has horizontal positioned, coolant jacket is corresponding to the cooling pin that can insert in the semi-finished product, this device has control device in order to control, handles semi-finished product and cooling pin and uses compressed air and all motions of suction air in case of necessity.
Background technology
Institute for whole circulation when making moulding is a deciding factor free cool time.Main cooling power occurs in the cast half module.Two cast half modules violent water-cooled in casting process, the temperature that makes also the moulding in 280 ℃ mould roughly can be reduced to scope at 70 ℃ to 120 ℃ at marginal layer at least.In skin, pass through about 140 ℃ of so-called glass temperature soon.Recently, when making the heavy wall semi-finished product, can reduce to about 12 to 15 seconds, reduce to below 10 seconds for the thin-walled semi-finished product to taking out notes part real casting process before.This has optimized quality for semi-harden semi-finished product.Semi-finished product must solidify in half module strongly, make semi-finished product be dished out auxiliary member (Auswurfhilfe) promptly with bigger power, and can indeformable or damage withdrawing device ground transfer.Withdrawing device has the shape adaptive with the moulding outside dimension.Carry out from outside to inside during at first at big wall thickness and delay time strongly in the strong water-cooled of cast in the half module according to physical condition.Be not consistent reaching on entire cross section of 70 ℃ to 120 ℃ of described temperature.The result is, as long as strong water-cooled undertaken by mould, in the material cross-section fast backheat carry out from inside to outside.The back cooling is main because two reasons.The first, the alteration of form before the dimensionally stable bearing state should be avoided surface damage and supporting-point etc. roughly.The second, must prevent to cross slowly and cool off in the high-temperature region, for example must adjust harmful crystal and form by backheat is local.Target is even amorphous state of final half-finished material.Residuals temperatures should be low make and damaging with on contact point, can not producing to adhere to during thousands of big packing of pouring part into of unclamping are connected.Moulding does not allow surface temperature to surpass 40 ℃ after slight backheat yet.Back cooling take out semi-finished product from injection machine after is the same important with the main cooling in injection molding.
US-PS 4 592 719 (Bellehache et al.) proposes, the following raising of half-finished productivity ratio: cool off with air.By suitable movement-oriented, inwardly and outwards, air is acted on the semi-finished product with the maximum cooling as the cooling air in transportation or when handling.Withdrawing device has and the as many suction tube of part produced in injection cycle and moving between two open half modules.Suction tube moves on on the semi-finished product then.Begin to be sucked flowing that pipe surrounds by the suction catheter air simultaneously, make in the moment of handing to the suction cover and cool off suction tube from the outside with air around the face zone each blow molding's part (Blasformteil) whole.Withdrawing device is shifted out by the half module space after delivering all mouldings of cast circulation fully.Half module is at once vacant and for subsequently cast circulation sealing once more at this.Withdrawing device is rolling the back semi-finished product of setovering of motion away from from the horizontal level to the upright position.Conveyer accurately sails to the position of delivering on the withdrawing device simultaneously.Conveyer has the interior grasping device of the suction tube as much that is had with withdrawing device.Just withdrawing device is put back and is sailed the position into after delivering all mouldings and before reopening half module, makes to back to back charging and can take out moulding from mould.Conveyer is handed to conveying device at interlude with moulding, not with semi-finished product turn back to and deliver the charging of position to carry out being close to later.
Known by the application WO 00/24562 (Nestal) before the applicant, for example avoid shelving single moulding and corresponding double plug, make when optimizing cooling effect and boost productivity.
The most important thing is the bottom cooling, form very little slit with coolant jacket after taking out from half module by the half-finished contraction in the coolant jacket is not shortcoming at once.This is the theme of EP 0 266 804, and it is by the taper configuration in the coolant jacket inboard and the semi-finished product outside and by little by little aspirating each slit between the semi-finished product discharge semi-finished product outside and the coolant jacket inboard.Here cooling sole not fully.
EP 0 947 304 (Husky) has proposed a task, promptly improves cooling effectiveness and half-finished quality and shortens total cycle time.The problem that crystal formed when the document at first was described in the cooling of relatively poor back.Proposition is used air cooled interior vault part basically by controlled and compulsory blow gun, wherein cools off behind the taking-up semi-finished product in by open half module, should avoid localised crystal to form thus at once.
US-PS 6 332 770 (Husky) passes through by the problem among the cooling solution EP 0 947 304 of local convection cooling effect.Inner cooling mandrel imports in the inner vault part always.At first half-finished vault part is thus by the convection current cooling processing.Be accurately, mechanical forced ground is directed into mandrel with corresponding semi-finished product internal face and produces a difficult problem that contact, to reach 100 at first essential of the introducings or the accuracy of multicore axle more by importing the shortcoming of half-finished mandrel with the scheme of convection current contact cooling.Entire machine with all motions must constitute accurately, the even and contact of each single semi-finished product thus with having the pressure damage.
Described among the JS-PS 8-103948 (Footier KK) by back after taking out semi-finished product in the tool of production and cooled off the particularly advantageous scheme in semi-finished product ground.Can learn that also the half-finished cooling fully in the tool of production has prolonged whole injection cycle.Must hysteresis for a long time open mould, productivity ratio is reduced widely.Therefore propose a kind of aftercooler that separates fully be used for after taking out semi-finished product from the tool of production heat also semi-finished product.This permission reaches high cooling efficiency by simple structure.Semi-finished product are handed on the cooler with a large amount of cooling pins.In this each semi-finished product while inside and external refrigeration.Carry out interior cooling by the cooling pin that has insufflation channel in inside.The relative motion that imports cooling pin is forced to carry out by taking out robot.Cooling pin preferably has inflatable mouth.The air blowing beam directly perpendicular to the end of semi-finished product dome-shaped sealing, can and freely flow out in the semi-finished product open end in opposed direction upper edge semi-finished product inwall guiding then.This solution realizes the very high efficient of short as far as possible injection cycle time, whole production and avoids crystallization, is pouring into a mould the zone and is realizing thus producing high-quality semi-finished product with high as far as possible efficient especially.
Each described solution respectively has advantage.But advantage is a cost with special restriction or huge cost here.Important target is except that preventing that crystal from keeping shape forming in addition as far as possible when the cooling semi-finished product.In cooling, exist and make the crooked and incomplete axisymmetric danger of semi-finished product.The possibility of result is that single semi-finished product remain in the aftercooler, makes to produce described double plug at the when filling with substance that is close to.Second semi-finished product are enclosed within on its coolant jacket thus.Also draw, whole back cooling can be divided into two sections.Phase I is right after take out semi-finished product from half module after, and second stage is for continuing long back cooling.The stage of real difficulty is the phase I that influences the semi-finished product final mass strongly.Up-to-date important knowledge points out, suppressing fully that crystal forms is not purpose, but will be with the share-maintenance of the crystallization in the whole semi-finished product low as far as possible.
Task of the present invention is, optimize cooling when shortening injection cycle time and keeping high as far as possible quality, and it is as far as possible little to make half-finished crystal form share, and do not have big process technology cost or be used to make more costs of injection machine.
Summary of the invention
Method of the present invention is characterised in that; semi-finished product took out back to planar resting between the water-cooled coolant jacket fully and are dynamically imported by rectilinear motion open the watering of taking-up stage " A " Shi Zaicong in a) in the phase I in injection molding or the counterpart mould; and accurately cooling from the outside of shape once more; follow b) export semi-finished product at the strong cooling stage " B " of strong cooling; strong cooling comprises the half-finished whole inboard and the whole outside; cooling postpones by cooling pin wherein, and carries out after withdrawing device rolls away from fully by open half module.
Device characteristic of the present invention is, shape is coordinated mutually with the corresponding interior shape of part mould in the coolant jacket of the horizontal positioned of withdrawing device, make and between resting on the water-cooled coolant jacket to complete face after take out in the cooling semi-finished product outside fast, can import semi-finished product from water injection molding by rectilinear motion, and produce accurate shape once more, wherein withdrawing device is made of interior cooling stations, and export the semi-finished product of strong cooling stage, and can cool off on half-finished whole inboard and the whole outside, interior cooling is carried out by the cooling pin time-delay and after withdrawing device rolls away from fully by open half module.
Showed already that the first back cooling stage was difficult especially, because semi-finished product shape stability deficiency.Half-finished stage that the injection machine that blow molding's part is arranged in horizontal operation by the danger of thread spindle " bending " in taking-up easily with respect to screw element keeps flat the position in fact is a real problem.This is that at first the cool time in injection mould is minimum, and semi-finished product are also warm and corresponding soft.Keep flat the position if semi-finished product are positioned in the cooling phase I in the back, it tends to be located at downwards on the corresponding cooling external member so.Cooling contact coolant jacket cooling strongly below by improving in the lower area make stress to occur in semi-finished product, and semi-finished product has crooked tendency.If in the phase I of back cooling when watering that cooling is shortened in the injection molding single semi-finished product easy deformation, can not correct so and solidify the corresponding alteration of form of semi-finished product gradually.
Mainly based on a kind of like this cooling design, promptly single semi-finished product only import coolant jacket with blow molding's part in the cooling of back in the present invention.Stretch out coolant jacket at this threaded portion.This has very big advantage, and semi-finished product import the coolant jacket of withdrawing device by rectilinear motion, and can pull out once more.New solution proposes and then contact with coolant jacket is best after taking out from water injection molding in the stage of strong cooling especially, and the strong temperature that realizes short maximum thus descend and stabilize to final cooling then first after semi-finished product in the cooling stage.The half-finished dynamic input of the complete wall contact in coolant jacket is right after after taking out from water injection molding, but before finally cooling off for a long time, the advantage of following key is arranged:
Cooling effect is determined by physical condition, is maximum in the temperature difference cooling effect of just taking out from water injection molding between after heat semi-finished product and the coolant jacket.At this, semi-finished product be forced to ground fully fully on the inner face of coolant jacket by putting owing to direct heat conducting maximum produces big as far as possible surplus.Carry out the cooling very fast in the semi-finished product outside.The share that forms crystal is reduced to minimum.Also heat semi-finished product shift onto on the cooling frame with as far as possible little slit for keeping the shape accuracy from water injection molding, taking out the back.When handling, back to back symmetry keeps the shape accuracy thus at the semi-finished product that cool off fast after the taking-up.
First property surveyed test shows that new solution is keeping can shortening under the mass parameter situation half second circulation timei of cast fully, and this corresponding productivity ratio improves about 5%.Because semi-finished product take out from mould with higher temperature, therefore from mould, take out quickly than prior art.The air pressure of available minimum rests on also soft blow molding's part on the inwall of coolant jacket in the phase I of back cooling.
The present invention also proposes, and is undertaken by suction air and/or blow out air by the interior cooling of cooling pin, and wherein suction air and blow out air controllably switch on or off by valve.Particularly advantageously, interior cooling realizes that by the cooling pin on the support plate that is arranged in controlled motion cooling pin is imported semi-finished product inside synchronously after rolling withdrawing device away from fully, wherein cools off air and is blown on one's own initiative and/or sucking-off by the cooling air.Carry out and control the stroke and/or the power of input motion on the run duration of cooling pin by the rhythm of injection cycle.
The internal diameter of coolant jacket than heat also half-finished outside dimension the highest larger about a few percent millimeter.Can produce the blowing pressure and semi-finished product are rested on fully on the whole internal face of coolant jacket by suitably controlling suction air and blow out air.Rest on the internal face of coolant jacket for the first time at semi-finished product after, the face contact kept more a plurality of seconds, thus cooling effect was maximized.Produce each single half-finished rectification effect (Kalibrationeffekt) simultaneously.Correct effect and when making semi-finished product, might produce inaccessiable production standard of prior art and quality standard.Semi-finished product are pressed into accurate shape (Form) once more after taking out from water injection molding, make changing by watering the possible size of the crucial processing back cut-out first time that is injection molded into coolant jacket, particularly because one-sided lying in caused half-finished bending in the coolant jacket at once.Correcting effect makes semi-finished product earlier take out and realize thus the phase I of shorter cast circulation timei and the cooling of improvement back from mould.This especially pass as quickly as possible (Durchfahren) glass temperature aspect and thus pass as quickly as possible aspect harmful crystal formation favourable.Back cooling then can easily realize in the required time with respect to all mass parameters, produces the semi-finished product of first water and improves the productivity ratio of injection machine simultaneously.The present invention proposes a plurality of embodiments and multiple favourable scheme.
The first particularly advantageous embodiment is characterised in that, produces less the blowing pressure by cooling pin.In view of heat conduction as well as possible between semi-finished product and the coolant jacket inwall, make every effort to make semi-finished product as far as possible seamlessly to insert coolant jacket.Known in the prior art a solution, wherein semi-finished product are male-tapered, and part semi-finished product of packing into only when wherein beginning are inhaled on offside step by step with corresponding negative pressure, and the wall that maintenance and coolant jacket are good on whole cool time afterwards contacts constantly.Significant disadvantage is that half-finished bottom branch is only cooled off from the outside very poorly.In new solution, the non-time delay as far as possible ground of packing into completely dynamically, finish in seconds basically.The wall contact can less the blowing pressure be carried out when the strong cooling of residue.All have the air blow-off outlet and slightly seal for producing each cooling pin of the blowing pressure with respect to each semi-finished product.At this control blow out air and suction air, make and when strong cooling, in each semi-finished product, produce slight negative pressure, semi-finished product and coolant jacket inwall are suitable and correct semi-finished product thus.
The important target of new solution is to cool off to carry out stage by stage in violent cooling.After from water injection molding, taking out semi-finished product, eliminate the temperature contrast that exists in the semi-finished product as quickly as possible.Crystal share in the whole semi-finished articles is reduced as far as possible, and wherein semi-finished product enter complete shape stable state for back cooling then.If semi-finished product its whole outer shape when the cooling beginning of back has symmetry as well as possible, can almost get rid of safely because the so-called double plug danger that crooked semi-finished product and corresponding operating trouble cause.
According to second embodiment, interior cooling is finished by the cooling pin on the transmission grasping device by suction air, cooling pin enters semi-finished product inside synchronously after withdrawing device rolls away from fully, wherein keeping suction air to activate up to semi-finished product are handed on the aftercooler from withdrawing device in strong cooling back when the back cooling stations that separates transmits semi-finished product.Each cooling pin links to each other with vavuum pump when strong cooling, the cooling air that vavuum pump initiatively heats by the cooling pin suction.Violent interior cooling at least 2 to 7 seconds, keeps cool time or back cool time about 3% to 10% up to the enough intensity of generation semi-finished product outer surface.Strong cooling only is the part of whole back cooling.And temperature-averaging descends 20 ℃ to 40 ℃ when acutely cooling off.The violent prolongation of strong cooling stage is disadvantageous, can not increase in semifinished material because conduct heat.
