Description

The cooling system of mouth mould and parison mo(u)ld

The present invention generally speaking is relevant determinant Glass Containers molding machine.More particularly, the present invention relates to and in determinant Glass Containers molding machine, form in this part of embryo (or just type) counterpart mould, the cooling system of bottleneck guide ring and parison mo(u)ld.

In the forming process of Glass Containers, general way is earlier in the parison mo(u)ld part of Glass Containers molding machine, make just type or embryo, automatically this embryo is transferred to the blowing mould part of glasswork molding machine, then this embryo is blown out the shape the same with blowing mould.

In the parison mo(u)ld part of Glass Containers molding machine, the gob of melten glass falls into embryo; Parison plunger is pressed into parison mo(u)ld, and glass gob is pressed into embryo, makes it have the shape of parison mo(u)ld and parison plunger concurrently.

The parison mo(u)ld of Glass Containers molding machine partly includes a mouth mould, and it is made of two and half mouthfuls of moulds, is used for forming miniature bottleneck portion, and threaded neck is promptly arranged.

This miniature bottleneck portion, or threaded bottleneck just, the blowing mould that is used in the Glass Containers molding machine is partly caught embryo, makes embryo can be blown to the final form of Glass Containers.And be the thread neck part that has that this bottleneck portion has become finished container equally.

Because miniature bottleneck portion or threaded neck are to be used for catching embryo to blow, this bottleneck portion must be cooled to foot makes its physical property mass-energy bear the blowing process, meanwhile still can keep finished container consistence dimensionally; Yet miniature temperature but must be high enough to provide the required viscosity of blowing process.

So just have a problem, counterpart mould part will provide cooling, makes miniature bottleneck portion have consistence on physical strength and the size, and high temperature makes it to allow blowing will to allow the rest part of embryo base keep fully simultaneously.

For many years, adopted various means to cool off the different parts of the machine of mould-forming Glass Containers in the look-ahead technique.For example, can represent current state of the art, can be referring to the United States Patent (USP) 3,024,571 of Abbott etc., this patent provides inner cooling way for surface of glass die.Though this patent has disclosed freezing air and can be used to find in practice that by comprising the different parts of modular ring arm this method is not enough to provide effective process of cooling.Same relevant subject matter is the United States Patent (USP) 3,015,911 of payne, and this patent has disclosed a kind of special method of cooling, and bottleneck is formed on the Glass Containers.Yet this patent only relates to the blowing mould part in the forming of glass operation, does not relate to material base or embryo part.

In order to overcome the defective on the constructional feature in the process of cooled glass die surface, with the deficiency that remedies by current and used so far glass container forming product that mould is produced, primary goal of the present invention is that the parison mo(u)ld to glass shaper partly provides improvement details and characteristics, cool off the mouth and the parameatal part of the Glass Containers that has just formed, particularly described container fully in a kind of mode that control arranged.

The further target of the present invention provides the means of suitable control heat, and this heat can transmit between the surface of Glass Containers mould-forming, cools off the surface of this Glass Containers equably, make it above do not have fire crack and crackle.

Another target of the present invention is to select best cooling performance in forming blank or miniature process, makes the bottleneck of the Glass Containers of just having produced have smooth end, the mouth of true garden shape, make bottle cap suitably fit on seal up this container.

Another target of the present invention is that particularly, at the oral area of container, and this does not need to sacrifice the productivity and the output of each station of glass shaper for Glass Containers provides an all even sufficient method of cooling.

The invention provides such means, can under the condition of not damaging the glasswork quality, make the output and the machinery efficiency of glasswork, improve more than 10%.

Another important feature of the present invention is that it partly provides the cooling way that control is arranged for the blank of glass container forming machine, has reduced some aftertreatment, comprises the burr of clearing up glasswork.

In the present invention, the embryo forming section of determinant Glass Containers molding machine comprises parison mo(u)ld, it is made up of a pair of half module, be used for forming the major part of embryo appearance profile, comprise a mouth mould of splitting, and it is made up of one half mouthfuls of moulds, is used for forming miniature bottleneck portion or threaded neck; Comprise a bottleneck guide ring, it is maintained in the interior die of half mouthful of mould, is used for constituting the upper surface of miniature screw neck; Also comprise a parison plunger, form miniature inside by it.

It is contiguous that the mouth mould is arranged at gas storage enclosure, and last gas storage enclosure links with nestable mode and following gas storage enclosure.A garden week connected in star of last gas storage enclosure makes down the gas storage enclosure closure to lower opening in nestable mode.The circumferential groove of last gas storage enclosure and following gas storage enclosure match, and have formed a pneumatic starter and the gas storage enclosure effuser as acceptance and dispersion freezing air.

A collection of first cooling duct is arranged in the last gas storage enclosure, and they are opened along the circle spacing around this vertical shaft, and communicate with the effuser of gas storage enclosure from the vertical shaft radial outward configuration of parison mo(u)ld.

A collection of second kind of cooling duct arranged in the mouth mould, and they are opened along the circle spacing around this vertical shaft from the vertical shaft radial outward configuration of parison mo(u)ld, are arranged in first kind of cooling duct to align.

An effuser that moves towards to settle along circumference occupy between gas storage enclosure and the following gas storage enclosure; By the air pressure in the gas storage enclosure effuser, make gas storage enclosure be forced to move, contact with the mouth mould.Available holddown spring is strengthened this fusion.

Each parison mo(u)ld half module includes the third cooling duct of a collection of positioned vertical, and they are opened along the circle spacing around parison mo(u)ld, and two semi-closure of very moment mould and when being adjacent to parison mo(u)ld, and the 3rd cooling duct aligns with the second cooling duct in mouthful mould.

The internal recess that circular ring type is arranged in the parison mo(u)ld; When two half modules were closed, this internal recess was caught a mouthful mould,, and these two and half mouthfuls of die clamps was gone in the embryo two and half mouthfuls of die clamps together, made second in the 3rd cooling duct and mouthful mould in the parison mo(u)ld cool off the duct simultaneously and led to.

Cold air flow can be introduced in the air storing duct effuser with steam hose, and freezing air upwards flows and passes the first interior cooling duct of gas storage enclosure; Upwards flow through in mouthful mould again, be in the cooling of second below bottleneck guide ring duct part; Multiple in the bottleneck guide ring is passed at the upper reaches along the trench-type duct that circumference is settled, the bottleneck guide ring then is placed in half mouthful of mould interior circular annular groove; So far, cold air stream continues upwards to flow, and passes the second cooling duct part of the inherent bottleneck guide ring of mouthful mould top.

Part freezing air upwards flows and passes the 3rd cooling duct of settling in the parison mo(u)ld, and this part freezing air emits by the mould plate washer that overlays the parison mo(u)ld top.

The remainder of cooling air then radially outwardly, the per os mould, passing many notches that are radial arrangement along the circle spacing in the mouth mould outwards flows, thus, by cooling notch and the many cooling fins of radially settling that radially inserts arrangement between cooling groove, but the counterpart mould is done further cooling.

Like this, the cooling of mouthful mould is to rely on to make cold air flow many positioned vertical in upwards flowing through mouthful mould, along the second cooling duct of circumferentially-spaced; Also rely on the notch radiation formula ground that makes a part of freezing air pass radially arrangement outwards to flow out; The remainder of freezing air is directed upwards, flows through in parison mo(u)ld many arranged perpendicular, along the cooling duct of circumferentially-spaced.

The result be mouthful mould and parison mo(u)ld the two all be cooled, but a mouthful mould cools off stronglyer than parison mo(u)ld, like this, miniature bottleneck portion or threaded neck can be sufficiently cooled, make this bottleneck portion possess certain mechanical strength and dimensional stability, and the temperature of embryo remainder can keep enough high, to allow to be blow molded into pocket.

In order to realize the necessary method of cooling of the object of the invention, relied on circumferentially, be positioned at many air motions that critical point die wall portion is arranged.In fact, effectively a mouthful mould cooling is what partly to finish at the blank of glass container forming machine, here heat passes to above-mentioned mouth mould from the mold component of associated easily, and mouthful mould is in normal operation, be in parison mo(u)ld this on one side account for 80% of total operation time at least.So, effective cooling is realized in this part of parison mo(u)ld with in this stage of operating process, and does not realize partly at the blowing mould of minimum time of change expense that primary meaning is arranged.Like this, when in fact heat is taken or is transferred to the relevant parts of mouthful mould or other, have control or programme controlled cooling be important.Yet, because quite strict mold configuration is arranged, realize that a kind of simple and direct means cool off and the contacted mold component of the bottleneck of Glass Containers effectively in this part of blank, known so far is unpractical.

The object of the invention, particularly melten glass is being placed the parison mo(u)ld assembly form embryo, dependence is inserted relevant mouth mould and embryo molded parts when making bottleneck portion and complete base substrate with parison plunger, permission is effectively cooled off the mould part relevant with the glass container forming machine, specifically, the present invention relates to such process, comprise air-flow is advanced in prearranged passage, these passages are opened to cool off the surface through mould-forming effectively along the circle spacing in relevant mouth die wall portion, particularly cool off the miniature neck portion that is forming.Before this, thisly comprise that the die surface of mouthful mould is to come refrigerative with traditional cooling way, poor effect or inappropriate.

As everyone knows, when the production high quality glass products since glass, need two procedures when forming glasswork from the gob of melten glass; The first step is by suppressing gob in parison mo(u)ld, make the gob of melten glass form embryo or blank in this station, is second step then, forms final form at second station independently by the blowing mould device.Purpose of the present invention relates to first station at said process, and embryo or this part of blank are realized effectively cooling.Relevant especially with this side of embryo in the aforesaid operations process is that the problem of those effective temperature controls is opposite, relevant with the blowing mould part, then is the specific question of a size-constrained system.

Once adopted many methods to attempt the controlledly mold component of cooled glass container forming machine, but only obtain limited achievement, it is believed that it is the die surface of controlling containers qualities not to be provided the uniform temperature condition again for the cooling conditions of transporting because they have both allowed to possess fully in itself.

Purpose of the present invention allows more preferably shaped container, can make the surface of the neck or the mouth cylindrical part of container especially, and is in the end extremely smooth or smooth in the configuration, makes the container finish opening that a round configuration is arranged simultaneously.In order to make the bottle cap can be convenient and closely cover, in this part forming process of container, be necessary to select top condition.

Refer now to Fig. 3,9 and 10, the cooling of mouthful mould 28 and parison mo(u)ld 22 is in air passageways 212 by freezing air being infeeded gas storage enclosure 40 and the air pipe collector 32 that formed by last gas storage enclosure 40 and following gas storage enclosure 42, realizes.

The air that infeeds collecting tubule 82 upwards flows, and has passed the many first cooling ducts or the first row internal passages 214, and wherein passage 214 is spaced from each other along circumference, and in last gas storage enclosure 40 positioned vertical.A collection of cooling duct 214 in the last gas storage enclosure 40, aiming at a collection of second cooling duct or the inner duct 216 of second row, these inner ducts 216 are that the annulate shaft 217 that centers on mouthful mould 28 along the circumferential direction distributes in spaced mode, and are positioned vertical in mouth mould 28.

From blowing mould part (not shown), when sending the embryo forming section of Glass Containers mould shape machine back to, the mouth modular ring 28 of mouthful mould bases 30 is placed on the gas storage enclosure 40 very moment mould bases 30, and annulate shaft 27 is roughly overlapped with central shaft 185 mouthful mould 28; Cooling duct 216 then with cooling duct 214 concentric alignment correspondingly one by one.

The second cooling duct 216 is bigger than the first cooling duct 214 on diameter, therefore has the injection effect of air-flow from 214 to second cooling ducts 216, the first cooling duct.This injection effect helps to prevent that freezing air from revealing away between the basal surface 220 of the upper surface 218 of last acceptance cover 40 and mouthful mould 28.

The second cooling duct 216 makes the internal recess 38 of mouthful mould 28 be divided into cooling duct 222a of portion and 222b.Why the cold air flow that makes progress from cooling duct part 222a can pass bottleneck guide ring 36 and enter cooling duct part 222b, be owing to passed through cooling groove 224, these cooling grooves are to erect configuration, use around bottleneck guide ring 36 along the circumference (see figure 9) that distributes separatedly.

Moved upward and passed a part of cooling air in the second cooling duct 216 in mouthful mould 28, by many spaced along circumference, emit along the cooling notch of radially settling 226, in the surface 188 of notch progressive die mouth at 226 quarter 28, and in the outer peripheral edges 228 of admission port mould 28.

Upwards flow and passed the remainder freezing air in the second cooling duct 216, enter a collection of the 3rd cooling duct or the 3rd row internal passages 230, passage 230 is configuration around parison mo(u)ld 22 along circumference, and is the erection position therein.Remaining this part freezing air has passed through the top surface 196 of parison mo(u)ld 22 overflows, and drains by the 4th cooling duct or the 4th row internal passages 232, and this round road 232 is arranged in the plate washer 26.

Like this, mouthful mould 28 is refrigerative as follows, promptly allows airflow pass the cooling duct part 222a in the second cooling duct 216, through the cooling groove 224 of bottleneck guide ring 36, by the cooling duct part 222b in the second cooling duct 216, again through cooling notch 226.Pass the airflow of cooling notch 226, provide cooling by many cooling fin 234 counterpart moulds 28, cooling fin is settled on circumference, and is (see figure 10) between cooling notch 226.

Have found that it is favourable combining with a control valve device 236 and aforesaid mould plate washer 26.In this respect, both can adopt automatic plate washer by-pass valve control in response to temperature, also can adopt wieldy manually-operated gate, this manually-operated gate can all be in order to control suitable air capacity and refrigerative degree by the operator in conjunction with controlling with the passage of plate washer associated in a word.

In general, the cooling of the parison plunger 116 of embryo forming section 20 is upwards to flow by air, has passed vertical venting hole 156, and has been passed down through due to many 3rd vents 162.

The cooling of mouth mould 28 is to rely on many second cooling ducts 216, and these ducts distribute and positioned vertical separatedly along circumference; Many cooling notches 226 and many cooling off between the notch 226, along the cooling fin 234 of circumference setting have also been passed through in the cooling of mouth mould 28.

Compare along the method that the line of rabbet joint vertically is set with the outside surface 238 that passes mouthful mould 28, with being arranged to many second cooling ducts 216 in mouth mould 28 of access hole mould 28 internal surface positions more now, also can maintain enough strength and stiffness, thereby aspect the cooling of counterpart mould 28, this cooling duct 216 is more effective than the line of rabbet joint of look-ahead technique.

The cooling of parison mo(u)ld 22 is the portion of air that rely on the second cooling duct 216 of mouthful mould 28, and it directly has been upward through along circumference spaced, a collection of the 3rd cooling duct 230 of positioned vertical in mould 22.

Like this, since all cooling air is used to cooling vent mould 28, and have only portion of air to be used for cooling off parison mo(u)ld 22, this just obvious counterpart mould 28 provides bigger cooling.

Refer now to Fig. 3, cooling air is linked up by last gas storage enclosure 40 and many second cooling ducts 216, because the air pressure of gas storage enclosure collecting tubule 82 has produced elastic stress, just can flexiblely hold up last gas storage enclosure 40 and make it to touch mouthful mould 28, but because the rebound resilience of this elastic thrust and being restricted, so a mouthful mould 28 still allows to move downward, and is seated on mouthful mould bases 30.

Like this, when the half module 24a of parison mo(u)ld and 24b were closed, they can be closed and do not influence the applying on the surface 190 of the surface 189 of parison mo(u)ld 22 and mouthful mould 28, and reason is that mouthful mould 28 was exactly to be seated in downwards on mouthful mould bases originally.

Then, by first kind of frustum trochoidal surface 187, mouthful mould 28 rises and is sandwiched parison mo(u)ld 22, and the elastic thrust of air pressure gas storage enclosure 40 on ejection rises is effectively keeping going up the contact between gas storage enclosure 40 and the mouth mould 28 in gas storage enclosure collecting tubule 82.Many the 3rd cooling ducts 230 of many second cooling ducts in the very moment mould 28 and parison mo(u)ld 22, when communicating with each other, just can make between many first cooling ducts 214 and the many second cooling ducts 216 and link up by the clamping effect of first kind of frustum trochoidal surface 187.

The result is, as long as a mouthful mould 28 is placed on the embryo forming section 20 of determinant Glass Containers molding machine, the continuous cooling of counterpart mould 28 just arranged, and this will account for about 80% of the full cycle time; In case and the half module 24a of parison mo(u)ld and 24b be when closed, also be successive to the cooling of parison mo(u)ld 22.

So mouthful mould 28 has the reason of bigger cooling journey than parison mo(u)ld 22, be not only because whole air has been conducted through many second cooling ducts 216, and only some freezing air is conducted through many 3rd cooling ducts; Also since freezing air be conducted through many second coolings during the duct when freezing air is conducted through the 3rd cooling duct 230, occupy the time of big per-cent.

Like this, target of the present invention promptly will give mouthful mould 28 so that bigger cooling degree to be arranged than parison mo(u)ld 22, reaches; Resulting embryo 198, its bottleneck 202 is colder than body part 208.

The result who obtains is that the bottleneck portion 202 of embryo 198 has the stability on sufficient mechanical and the size, is enough to bear the power that imposes on bottleneck portion 202 in the blowing mould operation; Body part 208 has then kept enough heat and plasticity-, is allowed body partly is blow molded into the shape (not shown) of final product.

Though in aforesaid explanation, disclosed concrete equipment, should be understood that these explanations are in order to disclose principle of the present invention, for those skilled in the art that, obviously can make many changes based on the present invention.So protection scope of the present invention will be decided by appending claims.
