Specific embodiment
Below in conjunction with attached drawing, the present invention is illustrated.
Injection molding is will to inject raw material to be placed in heating cylinder (being commonly called as plasticiser) after heating compression moulding with screw rod or column
Plug apply pressure, be injected into solution through the nozzle of the end of barrel in the mold of required shape and fill up die cavity, it is several after cooling
Product is taken out in demoulding, this process is realized by injection moulding and mold.
And injection molding machine refer to will resin be added hot material cylinder heating device in, set in barrel by injection cylinder drive plunger
Or screw rod, required for heating zone (the preform injection or storing) material that material is sent to barrel is softened and is heated in heating zone
Thermoplastic is under the action of melt pressure by the mold of injection closure when temperature, plunger or screw rod elapse.Injection molding die
It is fixed on moving template and solid plate.Clamping system guarantees the closure of mold, and provides necessary locked mode pressure when injection,
Injection molding machine can control the molding cycle of product equipped with time, pressure, flow, regulating system.Referring to Fig. 2, controller connects
Connect several sensors, by the control control such as servopump electromagnetism valve injection, open mold, thimble, penetrate platform etc. including operation.
Process of injection molding includes charging, heating plasticizing, molding, vasopressing injection, pressure maintaining, cooling and shaping, die sinking, demoulding
Deng wherein heating plasticizing, vasopressing injection, cooling are most important three steps in forming process.The present invention is on those bases
Corresponding step is added, makes its moulding mold processing parameters Automatic Optimal.The present invention realizes a kind of moulding mould process
The automatic method of parameter setting.The configuration of the relevant technological parameter of mold is to be obtained by the debugging of multiple injection cycles come automatic
It arrives.Operator only need to complete corresponding configuration step by the gradually guidance of software.Meanwhile operator only needs simple mesh
The quality for the moulding that each injection cycle generates is surveyed, and then the judgement for making on software Yes/No can be completed entirely to match
Set process.The present invention can assist in some basic, important technical parameter configurations that operator completes new die.
(1) feed: each feeding quantity should keep centainly, to guarantee injecting plasticizing uniformity, reducing injection moulding as far as possible
When pressure fluctuation.
(2) first stage technological parameter configuration phase: it is used to determine related Initialize installation.This process is in plasticizing
Before, it can also be arranged before addition, control system receives operator and inputs basic setting in this step.For example, material
The type of material, the basic size etc. of moulding.According to the input information of operator, for example, material type and moulding base
This size and die information match pre-stored technological parameter.These pre-stored technological parameters are stored in the one of software
In a database.User can increase technological parameter relevant to new material and enter in database, can also be to existing data
It modifies and updates.The material category and the trade mark that software is inputted according to user, call standard technology corresponding with the material
Parameter is configured.These parameters include calcining temperature, mold temperature, melt adhesive temperature, plasticizing rate, maximum injection pressure and most
Big injection speed etc..
A simply example is lifted, first: pre-establishing material information (such as material category and the trade mark etc.) and standard technology
Parameter correspondence database, those parameters include calcining temperature, mold temperature, melt adhesive temperature, plasticizing rate, maximum injection pressure and
Maximum injection speed.Again, it pre-establishes parameter limit value database, when subsequent each adjusting parameter, goes to judge whether parameter reaches
To limit value, if so, directly terminating.
(3) multiple injection cycle debugging, final adjustment to suitable parameter.Wherein each plasticizing is that plastics are being entered mould
To reach defined temperature before chamber, sufficient amount of molten plastic to be provided, to guarantee being carried out continuously for production.This process
Subsequent to highlight: injection refers to that injection molding machine plunger or screw rod add pushing force to pass through the material melted in barrel in the plastics of melting
Nozzle gate enters the process in die cavity；Pressure maintaining is this period that injection piston or screw rod start before return after injecting
Interior, pressure maintaining can keep the integrality of product to prevent molten plastic refluence from returning in running channel again, and compensate volume contraction.
(4) optimization dwell pressure setting, adjustment turns pressure maintaining position and the size of dwell pressure completes qualified samples injection.
Specifically introduce multiple injection cycle debugging, final adjustment to suitable parameter.
In general, control system automatically selects typical process parameter after overmatching dynamic parameter.
First stage, this method attempts to control screw rod in the case where no back pressure or plunger is plasticized.If setting
Melten gel movement is unable to complete in the fixed melten gel time, it is necessary to manually complete melten gel movement.Then, it attempts in the feelings for only using pressure maintaining
Entire mold is filled under condition.
According to the actual state of product, user selects whether mold is filled up completely.According to the user's choice, it is injected to calculate
Speed, dwell time etc..
The calculating of mobility:
Dwell time calculates:
The calculating of cooling time:
At this point, some obtained including cooling time, the initial value for turning the technological parameters such as pressure maintaining position and melten gel stroke.
Subsequently into second stage step.
Second stage step: by the debugging of several injection cycles, suitable molding proces s parameters are determined.
In this stage, a moulding is repeatedly injected under conditions of no pressure maintaining.Per injection is completed, and use is received
Whether the input validation moulding in family is complete to confirm that whether mold fills up.If mold confirmation is filled with, second stage
Just complete.
If mold does not fill up, following some technological parameters will specifically complete situation be adjusted automatically according to product
It is whole:
Injection speed
Injection pressure limit value
Turn pressure maintaining position
Barrel temperature
Mold temperature
Dwell time
Cooling time
If mold does not fill up, first adjusts injection speed, injection pressure limit value, turns pressure maintaining position, barrel temperature, mold
One or several parameters of parameter including temperature, dwell time, cooling time, such as injection speed, injection pressure limit value, turn guarantor
Pressure position is adjusted according to following formula and is injected again, if the moulding does not have complete, mold is not filled up, then will injection
Speed, injection pressure limit value turn pressure maintaining position and are adjusted according to following formula to be injected again, until moulding is complete.When
So, following formula is merely illustrative of, and is not limited to this.In addition, at each adjustment period, when mold temperature, pressure maintaining
Between, cooling time can also make the modification that adaptability makes one or several parameters.
Such as:
Injection pressure (new)=injection pressure (reality)+0.1* maximum injection pressure
Injection speed (new)=injection speed (reality) -0.1* maximum injection speed
Turn pressure maintaining position (new)=turn pressure maintaining position (reality) -0.05* screw diameter
In this stage, it may be necessary to operator to proceed as follows:
Clear material manually
Manual melten gel
Adjust mold temperature
This is because the retained material in screw rod must just be cleared up manually, if increasing mold temperature to prevent
There is degraded performance because of prolonged heating in the material remained in screw rod.In this case, it is also desirable to carry out manual
Melten gel operation.
If algorithm has been obtained suitable technological parameter and fills up mold, the phase III can be carried out.
If not obtaining suitable technological parameter or relevant parameter being more than the limit value of machine or material, this algorithm be will call the police simultaneously
It stops working.
Phase III step: adjustment dwell pressure.
After second stage obtains suitable technological parameter, in order to fill die cavity, dwell pressure can be optimized in the phase III
Setting.By several injection cycles, system can adjust the size for turning pressure maintaining position and dwell pressure.Operator needs to determine each
Period gets the quality of sample.If increase dwell pressure after, operator at most allow by several injection cycles (such as
5 injection cycles) come judge increase dwell pressure whether can be improved product quality.
If increasing dwell pressure product quality to be unable to improve or unqualified, this algorithm will report an error and out of service.
If operator thinks the up-to-standard of product, and residual silkgum content is stablized, and a molding moulding is then got.At this point, algorithm
Successfully terminate.
Dwell pressure (new)=dwell pressure (reality)+0.1* maximum dwell pressure
Embodiment one
A kind of method of moulding mold processing parameters Automatic Optimal, comprising the following steps:
In the first stage, user runs the corresponding software for implementing this algorithm, input initialization parameter, algorithm on injection molding machine
The information of input can be matched with pre-stored corresponding technological parameter, and the numerical value of proposed standard technological parameter.
Plastic material essential information input interface such as Fig. 3
For example, system can be automatically by database after user selects ABS material and selects detailed material trademark
User sets calcining temperature representative value as 83 DEG C, and maximum value is 93 DEG C.It equally, is 40 DEG C when user inputs mold temperature representative value
When, system is that user sets minimum value as 40 DEG C automatically, and maximum value is 60 DEG C.It further includes melten gel temperature that similar parameter is set automatically
Angle value, plasticizing rate value etc..
In addition, user also needs to input some essential informations for the product and its mold to be produced.For example, product is averaged
Wall thickness and thickest, diameter of mould gate etc..Then user needs to confirm some primary conditions of entire algorithm operation.
For example, whether mold is installed in place, whether mold temperature reaches setting value etc..
It is set by above user, this algorithm calculates corresponding technological parameter, then carries out no back pressure and be plasticized automatically.
If automatic plasticizing is completed at the appointed time, enter injection process.Otherwise, it into manual plasticizing process, is moulded manually
Enter injection process after change.
Then algorithm can calculate the data including injection speed, dwell pressure, cooling time and melten gel stroke, and in terms of this
It calculates result and carries out first time injection, and attempt to fill up mold in the case where only pressure maintaining.This is primarily to guarantee that mold exists
Not by accidental damage in injection process.When controller detects screw rod stop motion, the movement of mold filling just finishes.
Then, algorithm can be plasticized by applying a lesser back pressure, and carried out second and injected.Then, user
It needs to feed back to algorithm, by above-mentioned double injection, whether mold is filled up completely.According to the difference selection of user, algorithm can be into
The corresponding technological parameter of one successive step.And before entering second stage, corresponding technological parameter is shown to user.
In second stage, if user feedback to algorithm is that mold is filled up completely in previous step, algorithm can be into one
Whether step confirmation injection pressure reaches limit value.If not reaching limit value, algorithm enters the phase III.If reaching limit
Then value carries out injection again and confirms mold filling result to user then algorithm will adjust injection pressure limit value.Until mould
Tool is filled up completely and injection pressure does not reach limit value.
If at the end of the first stage, user feedback is that mold is not filled up completely to algorithm.So algorithm will be adjusted
Whole a series of technological parameter (injection pressure limit value, injection speed, mold temperature, melt adhesive temperature etc.), to be injected simultaneously
It is required that user confirms effect.This development is periodic.
Technical arrangement plan interface such as Fig. 4
If be unable to reach be filled up completely or technological parameter be more than machine and material limit value, algorithm you can't get
Reasonable technological parameter, to terminate and alarm.
In the phase III, algorithm needs come on the basis of applying pressure maintaining so that mold is filled up completely.At this moment turn pressure maintaining position
It sets and just needs to adjust and determine with pressure maintaining size.Algorithm will adjust the two key parameters, and carry out periodic injection operation.
User will judge whether mold is filled up completely after per injection is complete, and adjust whether have improvement every time.Algorithm according to
The feedback at family, further adjusting process parameter, and finally obtain a qualified product.If calculated by 5 adjustment and injection
Method is again without qualified products are obtained, then algorithm is terminated and alarmed.If obtaining a qualified product, need manually
Remaining material and manual melten gel are removed, a qualified product is finally obtained, corresponding technological parameter is also stored in by algorithm
In controller of plastic injection molding.
Finally obtained successful result interface such as Fig. 5
Implementation of the invention may include a set of corresponding human interface software, and operator's input initialization is facilitated to believe
Breath, and entire debugging process is gradually completing according to software prompt.Meanwhile after judgement sample quality, operator can also lead to
It crosses human interface software and inputs the option of yes/no simply to decide whether the subsequent debugging into next stage.Finally, software
Can succeed sample appropriate process parameter and save.The exploitation of corresponding software, is completed in our company
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to above-mentioned implementations
Mode.Even if to the present invention, various changes can be made, if these variations belong to the model of the claims in the present invention and its equivalent technologies
Within enclosing, then still fall within the protection scope of the present invention.
