This solution achieves precise temperature control of the injection molding machine by providing temperature sensors to record temperature rise time, monitoring inlet and outlet flow rates, extracting pipeline paths at different temperatures and switching them online, comparing pipeline temperature output with preset temperatures in real time, and displaying pipeline temperature status online.

[0089] According to a first aspect of an embodiment of the present invention, a mold water channel intelligent flow control method is provided.

[0099] Figure 2 The present invention is a flowchart of setting an injection molding machine control structure in a mold water channel intelligent flow control method according to an embodiment of the present invention.

[0100] like Figure 2 As shown, in one or more embodiments, preferably, the setting of an injection molding machine control structure specifically includes:

[0101] S201, setting an injection molding machine control structure including a power supply unit, a central processing unit, a servo drive unit, a servo motor unit, an execution control unit, a valve body unit, and a sensor unit;

[0106] S206, the execution control unit transmits the CPU instruction to control the IO output;

[0107] S207, the valve body unit receives the instruction from the execution control unit and executes the action;

[0108] S208: The sensor unit feeds back to the execution unit whether the execution is performed according to the instruction.

[0109] In an embodiment of the present invention, an injection molding machine control system includes at least one central processing unit (CPU), a servo drive unit, multiple servo motors for driving shaft motion, each motor corresponding to a corresponding servo drive unit, an execution control unit (IO control unit), a valve unit, a sensor unit, and a power supply for supplying power to the control system. The CPU serves as the core of the control system, and the power supply unit, servo drive unit, and execution control unit are connected to it via power cables, IO cables, and communication cables, respectively. The servo motor unit, serving as the servo drive's execution unit, is directly connected to the servo drive; the execution control unit is directly connected to the CPU via a communication cable; the valve unit is connected to the output signal of the execution control unit; and the sensor unit is connected to the input signal of the execution control unit. The CPU is responsible for issuing and receiving feedback commands. Signals are centrally issued by the CPU, and the servo drive unit and execution control unit receive these commands and distribute them to the next-level execution unit. The servo drive unit receives signals from the CPU to control the forward and reverse rotation, acceleration and deceleration, and start and stop of the servo motor unit. The servo motor unit executes signals from the servo drive unit to drive other components. The execution control unit receives signals from the CPU to control the input and output of IO signals. The valve unit receives the signal from the execution control unit to execute the valve opening and closing action. The sensor unit transmits the feedback of the valve body action and the servo position action to the central processing unit, which analyzes whether it is executed according to the instruction.

[0110] Figure 3 This is a flow chart of a mold waterway intelligent flow control method according to an embodiment of the present invention, in which a temperature sensor is set at the outlet of each pipeline path to record the temperature rise time.

[0111] like Figure 3 As shown, in one or more embodiments, preferably, a temperature sensor is provided at the outlet of each pipeline path to record the temperature rise time, specifically including:

[0112] S301, recording the current time when the entire pipeline is at the current ambient temperature;

[0113] S302, recording the time it takes for the outlet temperature to rise to the maximum required temperature;

[0114] S303. Record the time it takes for the outlet temperature to drop to the minimum required temperature.

[0115] In an embodiment of the present invention, a temperature sensor device is installed at the outlet of each pipeline path to monitor temperature changes in real time and record key time points. The specific implementation method is as follows: First, when the entire pipeline is at the current ambient temperature, the system will record this moment as a reference point. For example, assuming the ambient temperature is 25°C, when the entire pipeline reaches this temperature, the system will automatically mark the timestamp of this moment, such as "June 1, 2024 10:00:00". Next, the system begins the heating process until the outlet temperature rises to the maximum required temperature. To use a specific example, if the maximum required temperature is set to 180°C, then the time is counted from the reference point until the outlet temperature sensor detects that the temperature has reached 180°C, and this time is recorded. Assuming this process takes 3 minutes, it will be recorded as "June 1, 2024 10:03:00". Then, the system enters the cooling phase. Similarly, when the outlet temperature drops to the minimum required temperature, the time of this moment is recorded again. Assuming the minimum required temperature is set at 80°C, and the process of decreasing from the maximum temperature to 80°C takes 5 minutes, the time will be recorded as "June 1, 2024, 10:08:00 AM." This allows accurate information on the time required to reach the target temperature under different conditions (such as varying flow rates and initial temperatures). This data is crucial for optimizing production processes and improving product quality. For example, if a particular step is found to be taking too long or too short, parameters can be adjusted promptly to improve efficiency or ensure quality. Furthermore, this detailed record facilitates subsequent fault analysis and enhances equipment maintenance.

[0116] Figure 4 The present invention is a flowchart of an intelligent flow control method for a mold waterway according to an embodiment of the present invention for monitoring inlet flow and outlet flow.

[0117] like Figure 4 As shown, in one or more embodiments, preferably, the inlet flow monitoring and outlet flow monitoring specifically include:

[0118] S401, separately setting flow sensors at the inlet and outlet of the pipeline;

[0119] S402: The pipeline flow rate is collected online through a flow sensor, and the average value of the pipeline inlet and outlet is used as the pipeline flow rate.

[0120] In an embodiment of the present invention, flow sensors are first installed at the inlet and outlet of a pipeline. These flow sensors can measure and record the water flow rate passing through that point in real time. For example, in a typical application scenario, assume that the instantaneous flow rate measured by the inlet flow sensor is 5 liters / minute, while the instantaneous flow rate measured by the outlet flow sensor is 4.8 liters / minute. Next, the system uses these two flow sensors to collect flow data in the pipeline online. To ensure data accuracy, the inlet and outlet flow values are averaged. In this example, the average flow rate will be (5 + 4.8) / 2 = 4.9 liters / minute. This average value will be used as the actual flow rate of the entire pipeline for subsequent calculations and controls. In this way, the actual flow rate in the pipeline can be more accurately understood, thereby better controlling temperature fluctuations. This precise flow monitoring not only helps improve product quality, but also effectively reduces energy consumption and extends equipment life. In addition, real-time flow data can be used for fault diagnosis and maintenance planning, further improving production efficiency and safety.

[0121] Figure 5 This is a flow chart of extracting pipeline paths at different temperatures and performing pipeline settings online in a mold waterway intelligent flow control method according to an embodiment of the present invention.

[0122] like Figure 5 As shown, in one or more embodiments, preferably, the extracting pipeline paths at different temperatures and performing pipeline settings online specifically include:

[0123] S501. Obtain the time required to heat the temperature from normal temperature to the maximum required temperature at the current flow rate as the heating time;

[0124] S502: Obtain the time required to rise from normal temperature to the minimum required temperature at the current flow rate as the cooling time;

[0125] S503, calculating the required pipeline duration using the first calculation formula;

[0126] S504, calculating the pipeline distance using a second calculation formula;

[0127] S505, calculating the safety distance using the third calculation formula;

[0128] S506: Setting a segmented pipeline in the shape of a petal, where the edges of the petals are segmented pipelines. A valve is set in the stamen area to determine whether the pipeline passes through the edge of the petals. The side length of each petal is L, and there are N segments of petals in total.

[0129] S507, calculating the total number of opened petal pipelines using the fourth calculation formula;

[0130] The first calculation formula is:

[0131] TX=max(T1,T2)

[0132] Among them, max is the maximum value extraction function, T1 is the heating time, T2 is the cooling time, and TX is the demand pipeline time;

[0133] The second calculation formula is:

[0134] B=TX×V

[0135] Wherein, B is the pipeline distance and V is the pipeline flow rate;

[0136] The third calculation formula is:

[0137] AN=1.3×B

[0138] Among them, AN is the safety distance;

[0139] The fourth calculation formula is:

[0140] M=Z(AN÷L)

[0141] Where Z is the rounding function and M is the total number of open petal pipelines.

[0142] In this embodiment of the present invention, the system calculates the time required to rise from ambient temperature to the maximum required temperature (heating time) and the time required to fall from ambient temperature to the minimum required temperature (cooling time) based on the current flow rate and temperature requirement. For example, assume the current flow rate is 10 liters / minute, the maximum required temperature is 80°C, and the minimum required temperature is 60°C. Experimental data or a pre-set model can determine that the heating time is 5 minutes and the cooling time is 3 minutes. Next, the system uses the first calculation formula: TX = max(T1, T2), where T1 is the heating time, T2 is the cooling time, and TX is the required pipeline time. In this example, TX = max(5, 3) = 5 minutes. The system then uses the second calculation formula: B = TX × V, where B is the pipeline distance and V is the pipeline flow rate. In this example, if the pipeline flow rate is 10 liters / minute, B = 5 × 10 = 50 meters. Next, the system uses the third calculation formula: AN = 1.3 × B, where AN is the safety distance. In this example, AN = 1.3 × 50 = 65 meters. The system then sets up segmented pipelines in the shape of petals, with the edges of the petals serving as segmented pipelines. A valve is installed in the pistil area to determine whether the pipeline passes through the edges of the petals. Each petal has a side length of L, with a total of N segments. For example, the length L of each petal segment can be set to 10 meters, for a total of 5 segments. Finally, the system uses the fourth calculation formula M = Z (AN ÷ L), where Z is the rounding function and M is the total number of open petal pipelines. In this example, M = Z (65 ÷ 10) = 7. This means that 7 petal-shaped segmented pipelines need to be opened to meet demand. This method ensures accurate control of the pipeline path at different temperatures, thereby achieving precise temperature control of the injection molding machine. This design not only improves production efficiency but also reduces energy consumption and maintenance costs.

[0143] Figure 6 This is a flow chart of a mold water channel intelligent flow control method according to an embodiment of the present invention for obtaining pipeline temperature measurement output in real time and performing pipeline adjustment online.

[0144] like Figure 6 As shown, in one or more embodiments, preferably, the real-time acquisition of the temperature measurement output of the pipeline and online pipeline adjustment specifically include:

[0145] S601, obtaining the temperature measurement output of the pipeline in real time and comparing it with the preset given temperature;

[0146] S602: When the fifth calculation formula is satisfied, the required pipeline duration is updated; otherwise, the original required pipeline duration is maintained unchanged;

[0147] The fifth calculation formula is:

[0148] |G1-G0|>5℃

[0149] Among them, G1 is the temperature measurement output of the pipeline, and G0 is the preset given temperature.

[0150] In this embodiment of the present invention, the system obtains the pipeline's temperature measurement output in real time, namely the actual temperature value of the current pipeline. For example, suppose that at a certain point in time, the pipeline's temperature measurement output is 75°C. The system then compares this actual temperature value with a preset set temperature. In this example, the preset set temperature may be set to 80°C. Next, the system determines whether the required pipeline duration needs to be updated based on the fifth calculation formula: |G1-G0|>5°C. In this formula, G1 represents the pipeline's temperature measurement output, and G0 represents the preset set temperature. If the absolute value of the difference between the two is greater than 5°C, it means that the actual temperature has deviated significantly from the preset temperature, and the required pipeline duration needs to be updated to adapt to the new temperature conditions. Conversely, if the difference does not exceed 5°C, the original required pipeline duration remains unchanged. In this way, the pipeline path can be accurately controlled under different temperature conditions, thereby achieving precise temperature control of the injection molding machine. This design not only improves production efficiency but also reduces energy consumption and maintenance costs.

[0151] Figure 7 This is a flow chart for online display of the temperature in the entire pipeline in a mold water channel intelligent flow control method according to an embodiment of the present invention.

[0152] like Figure 7 As shown, in one or more embodiments, preferably, the online display of the temperature in the entire pipeline specifically includes:

[0153] S701: When the pipeline flow rate is within the range of ±5% of the preset flow rate, it is set to a green flow state;

[0154] S702: When the pipeline flow rate is above 105% of the preset flow rate, it is set to red flow state;

[0155] S703. When the pipeline flow rate is below 95% of the preset flow rate, it is set to a yellow flow state.

[0156] In an embodiment of the present invention, the system monitors pipeline flow in real time and adjusts the color display of the pipeline based on flow rate fluctuations. For example, if the preset flow rate is 10 liters / minute, when the pipeline flow rate fluctuates within ±5% of this value (i.e., 9.5 to 10.5 liters / minute), the system will set the flow state to green, indicating normal and stable flow. If the pipeline flow rate exceeds 105% of the preset flow rate, or 10.5 liters / minute, the system will set the flow state to red, alerting the operator to a possible overload or abnormality requiring prompt inspection and action. Conversely, if the pipeline flow rate falls below 95% of the preset flow rate, or 9.5 liters / minute, the system will set the flow state to yellow, indicating that the flow rate is low and that adjustments to the pump speed or other relevant parameters may be necessary to ensure normal production.
