Abstract
The invention relates to a control technology for an injection molding machine, and aims to provide a temperature control method and a temperature control system for a plurality of sections of a barrel of the injection molding machine. The method comprises the following steps that: a temperature sensor acquires the current actual temperature value of each barrel section in real time and transmits the value to the corresponding proportion integration differentiation (PID) control module; each PID control module acquires the temperature control error value of each barrel section and calculates the original control output value of an electric heater of the corresponding barrel section; and a temperature synchronization algorithm module acquires the actual control output value of the electric heater of each barrel section and transmits the value to the electric heater of the corresponding barrel section for control. The temperatures of the plurality of sections of the barrel can be quickly and synchronously raised and controlled, and when the temperature error of the barrel of the injection molding machine exceeds a set error range in the normal operation process of the injection molding machine, a synchronous control algorithm can be expected to be realized, so that the injection molding production process is dynamically and synchronously controlled. By the control system and the control method, the hardware cost of the conventional control system is not changed, and the temperature control synchronism of the barrel is greatly improved.
Description
Technical field
The present invention relates to the control method and the system of injection machine, say in more detail, the present invention relates to the control of multistage barrel temperature in the injection machine and require control method and the system that control accuracy is high, synchronism is good.
Background technology
Plastics have become human society and have used one of topmost four big materials.Injection machine is that the macromolecule raw material are heated to the temperature that production needs through the barrel of injection machine, becomes molten state, will be heated to the polymeric fluid of molten state then, through the processing equipment of screw of injection cooling forming in the mould.Injection-moulding plastic is that the tool advantage of plastic products also is topmost processing mode, accounts for about 1/3 of whole Process Technology of Polymer gross weight, therefore in each field of national economy, occupies critical role.
The quality of injecting products receives the influence of macromolecular material, mould, injection machine and four aspects of Shooting Technique.Under the certain situation of macromolecular material, mould and the Shooting Technique of injection moulding, the quality of injecting products is directly determined by the technological parameter control accuracy of injection machine.The technological parameter of injection moulding comprises the speed, pressure, inject time, injection position, cool time, barrel temperature, nozzle temperature, mold temperature of each injection moulding action etc.And the most important process conditions of injection mo(u)lding are temperature, injection speed, pressure and injection volume etc. that the influence plasticizing is flowed and cooled off.Wherein the barrel temperature of injection machine control is one of pass key control technological parameter in the injection moulding processing technology, and melt temperature directly has influence on characteristics such as flowability and the specific volume of melt, and then influences the quality of converted products.And if barrel temperature is too low, plastics produce unnecessary shearing force between screw rod, and therefore produce cold curing, and machine is caused damage.Take place crosslinkedly when temperature is too high between plastic molecules, can make tissue looseness, produce foamed phenomenon, especially unallowed especially in precise injection molding.Therefore the temperature of injection machine fused mass need accurately be controlled.And the temperature controlling of melt is through to injection moulding barrel temperature controlling and indirect controlling.
In the injection moulding process of plastics, melt temperature is decided by the temperature of barrel and the shear heat between barrel inner screw and the plastics.It is generally acknowledged that melt temperature is decided by that the temperature that heats, the control of plastics temperature show as the temperature control to barrel in middle-size and small-size machine.The temperature control of injecting machine material tube generally adopts segmentation to control, and with the barrel of whole injection machine, from the injection port to the charge door, continuous is divided into several sections, and controls respectively, and control method is main with the PID control method.Each section temperature is provided with as required, generally each section temperature setting and inequality.
Research shows that injection machine multistage barrel temperature is to liking close coupling, large time delay and a non-linear object.At first, the section barrel of injection machine is actually a continuous integral body, owing to intercouple between each section of conductibility barrel temperature of temperature, the temperature control between the adjacent segment influences each other.Secondly, barrel temperature control of injection mold has the hysteresis characteristic of temperature object, according to type different its lag times from several seconds to a few minutes.The 3rd, the controlled target temperature of injecting machine material tube has uncertainty.At first its model can't or be difficult to accurate identification, receives various environmental factor factor affecting in addition, so accurately control is very difficult for it.
Present on the other hand control method is the stable state accuracy of an account temperature control basically, seldom considers for the dynamic response of control procedure.Because the difference that each section temperature is provided with and the lag time of each section barrel temperature are different with response speed, are different so each section barrel reaches the time of design temperature, reach the barrel section of design temperature early stage and must wait for the section that does not also reach setting value; Because the conductibility of temperature; Will inevitably have influence on the section of not reaching and add thermal control, and each section reach the asynchronism(-nization) of setting value, the actual heat time heating time of each section is different; Heating process must influence the characteristic of melt in the barrel; The uniformity of whole like this macromolecule melt characteristic is received influence, and then can respond the internal performance of converted products, like toughness, internal stress distribution and intensity etc.Therefore the synchronism of considering the control response of each section barrel temperature also will act on during the raising of injecting products quality is had.
Conventional at present barrel temperature control of injection mold algorithm is not all considered the requirement of Synchronization Control.The radiating condition of each section barrel temperature is different in addition, reach after the design temperature, owing to constantly continuously produce, and the continuous adding of raw material and dispel the heat inconsistently, the temperature error that causes is also different, so also there is the problem of a Synchronization Control.
