[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] In one embodiment, Figure 1 As shown, a method for intelligently adjusting a hot runner temperature control box based on artificial intelligence is provided, comprising the following steps: In a first aspect, the present application provides an intelligent adjustment method for a hot runner temperature control box based on artificial intelligence, the method comprising: Step S100: outputting a preheating signal and a heat preservation signal.

[0020] Among them, the preheating signal and the insulation signal are both PWM square wave signals with preset fixed values ​​of duty cycle and peak-to-peak value. When adjusting the preheating signal and the insulation signal, only the time of the square wave signal output per unit time is controlled. By outputting such preheating signal and insulation signal, the injection plastic in the flow channel can be heated to make it into a molten state. In some embodiments, when the device starts to heat the injection plastic and executes step S100 for the first time, the output preheating signal and insulation signal are manually input or system preset preheating signal and insulation signal. When executing subsequent steps, the preset preheating signal and insulation signal will be adjusted to achieve better preheating and insulation effect. In addition, the preheating stage can be completed synchronously with the injection plastic mixing stage. The injection plastic is heated in the process of mixing multiple injection plastics. In the insulation stage, the injection plastic can be kept in a molten state. On the one hand, it can flow in the hot runner, and on the other hand, it can also fully mix the multiple injection plastics that may exist, so that the texture of the mixed injection plastic is more uniform.

[0021] Step S200: Waiting for and acquiring the temperature signal after preheating and the temperature signal after keeping warm.

[0022] Among them, the post-preheating temperature is the temperature reached by the injection molding material after the preheating in the preheating stage. When setting the preheating signal, different preheating signals can be set for injection molding materials with different compositions so that the injection molding materials can be transformed into a molten state after completing the preheating stage; the post-insulation temperature is the temperature of the molten injection molding material after the insulation stage. The temperature of the molten injection molding material after the insulation stage (i.e., the post-insulation temperature) exists in three different situations: lower than, equal to, or higher than the post-preheating temperature. Ideally, the post-insulation temperature should be higher than the post-preheating temperature so that the molten injection molding material can maintain a flowing state, but it should not be heated to an excessively high temperature to reduce the heat power consumption in the insulation stage or avoid carbonization of the injection molding material. Therefore, the output power in the insulation stage should be controlled at a certain level. Since the injection molding material is an amorphous material, the temperature range in which it can maintain a molten state usually changes with the composition of the injection molding material. Therefore, it is necessary to dynamically adjust the output power in the insulation stage for different materials, that is, to adjust the insulation signal. Since both the preheating signal and the insulation signal are PWM square wave signals with preset fixed values ​​for duty cycle and peak-to-peak value, the purpose of adjusting the output power in the insulation stage can only be achieved by adjusting the output time of the insulation signal. One adjustment method that can be used as a reference is to adjust the output duration of the insulation signal per unit time. For example, the insulation signal is a PWM square wave signal with a duty cycle of 50%, a frequency of 50Hz, and a unit time of 1s. In the initial state, the output time of the insulation signal per unit time is set to only account for 75%, that is, 0.75s, and the remaining 0.25s is not output. When the temperature after insulation is lower than the temperature after preheating, the power of the insulation stage can be adjusted by appropriately adjusting the proportion of the output time per unit time. By adjusting the power of the insulation stage in this way, the requirements for the circuit, especially the frequency division circuit, of the traditional method of adjusting the duty cycle of the PWM signal can be reduced, and the control method of the system can be simplified, thereby saving costs.

[0023] In the embodiment of the present application, the specific steps of step S200 include: Step S210: Acquire the temperature T after preheating respectively a The temperature signal after preheating and the temperature after insulation T b The temperature signal after insulation.

[0024] Step S220: The preheated temperature T a and the temperature after insulation T b Substitute the preset heating constant calculation relationship to obtain the injection molding material heating constant A.

[0025] Among them, the preset heating constant calculation relationship is as follows: A=P b ·t b / (T b -T a ) In the above relationship, P b is the heating power corresponding to the insulation signal, t b It is the heating time of the insulation signal.

[0026] Through step S210 and step S220, the temperature before and after the insulation stage, that is, the temperature after preheating T a Temperature after insulation T b The key parameter that affects the hot runner heating power and temperature change is calculated, namely the heating constant A. The heating constant A is related to the mass of the molten material heated in the insulation stage and its specific heat capacity. Under normal circumstances, the volume and density of the molten injection material in the insulation stage are constant. Therefore, the heating constant A is related to the specific heat capacity of the molten injection material, that is, the heating constant A is directly related to the physical properties of the molten injection material. This parameter is of reference significance for adjusting the power in the insulation stage and the power in the warming stage.

[0027] Step S300: Determine whether the temperature signal after heat preservation is greater than a preset first temperature threshold.

[0028] The first temperature threshold is the lowest temperature preset by the system that can maintain the fluidity of the injection molding material.

[0029] Step S400: If not, adjust the preheating signal and the heat preservation signal so that the temperature signal after heat preservation is higher than the preset first temperature threshold.

[0030] Through step S300 and step S400, the injection molding material can be kept in a molten state during the heat preservation stage and have better fluidity, thereby avoiding blockage in the hot runner.

[0031] In step S400, the specific steps of adjusting the preheating signal and the heat preservation signal so that the temperature signal after heat preservation is higher than the preset first temperature threshold include: According to the temperature T corresponding to the temperature signal after insulation b and a preset first temperature threshold T b ', adjust the heating time of the heat preservation signal. Among them, the first temperature threshold T is preset b ' is the temperature value that the molten injection material should maintain after the insulation stage is completed, which is manually input.

[0032] Step S500: inputting the temperature signal after heat preservation into a preset temperature compensation relationship to calculate a temperature compensation signal parameter, and outputting a temperature compensation signal according to the temperature compensation signal parameter.

[0033] Among them, the preset temperature compensation relationship is as follows: D = A (T c -T b ) / P cmax ·t c Among them, D is the temperature compensation signal parameter, A is the injection molding material heating constant, T c is the preset compensation target temperature, T b is the temperature after insulation, P cmax is the peak heating power corresponding to the temperature compensation signal, t c It is the preset compensation heating time.

[0034] Through the above steps, the injection molding material can be subjected to three different heating stages, namely, preheating, heat preservation and temperature compensation. The purpose of the preheating stage is to enable the injection molding material to be transformed from a solid state to a molten state, and to facilitate the full mixing of a variety of mixed injection molding materials. The purpose of the temperature compensation stage is to enable the injection molding material to maintain a molten state capable of flowing in the hot runner. The heating power of this link should not be too low or too high. It is necessary to reduce the output power while maintaining the injection molding material with better fluidity, so as to achieve the purpose of energy saving. The purpose of the temperature compensation stage is to heat the injection molding material to a temperature suitable for extrusion by heating for a short time. Since the injection molding process is intermittent, the temperature compensation signal parameter, that is, the duty cycle of the temperature compensation signal, can be adjusted according to the time of the extrusion action and the target temperature, thereby adjusting the output power of the temperature compensation stage. In the three different heating processes, the key parameter affecting the heating effect is the heating constant A of the injection molding material, which can be calculated through step S200. Therefore, when implementing the method, the heating constant A of the injection molding material can be detected online, thereby dynamically adjusting the output power of the temperature compensation stage and the heat preservation stage, thereby improving the yield rate of injection molded parts.

Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
