Detailed Implementation

[0032] The present invention will now be described in conjunction with specific embodiments.

[0033] Example 1, as Figure 1 As shown, a mold production data visualization offline monitoring system is provided. The mold is a hot runner mold and includes an upper mold plate 1 and a lower mold plate 2 located below the upper mold plate 1. A molding chamber 3 is provided between the upper mold plate 1 and the lower mold plate 2. Hot runners 4 are respectively opened inside the upper mold plate 1 and the lower mold plate 2.

[0034] Among them, such as Figure 1 and Figure 2 As shown, the mold production data visualization offline monitoring system includes a display screen 5 and several mold temperature sensors 6, and mold temperature sensors 6 are installed on the upper mold plate 1 and the lower mold plate 2 respectively.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the mold production data visualization offline monitoring system also includes an MCU microcontroller 7, an SD card memory 8, and several hot runner temperature sensors 9 for monitoring the temperature of the hot runner 4. The upper template 1 and the lower template 2 are respectively equipped with hot runner temperature sensors 9.

[0036] Furthermore, such as Figure 2 As shown, each mold temperature sensor 6, display screen 5, each hot runner temperature sensor 9, and SD card memory 8 are electrically connected to the MCU microcontroller 7.

[0037] During the monitoring of production data in the mold production process using the mold production data visualization offline monitoring system of this embodiment, each mold temperature sensor 6 collects the temperature of the corresponding upper mold plate 1 and lower mold plate 2 and feeds the temperature data back to the MCU microcontroller 7 in real time. Each hot runner temperature sensor 9 collects the temperature of the heating medium inside the hot runner 4 of the corresponding upper mold plate 1 and lower mold plate 2 and feeds the temperature data back to the MCU microcontroller 7 in real time. The MCU microcontroller 7 processes the above temperature data and sends the processing results to the display screen 5 and the SD card memory 8 respectively. The display screen 5 displays the temperature value of each temperature monitoring position in real time so that the staff can know the temperature situation in the mold production process through the display screen 5. The SD card memory 8 is used to store the above temperature data for retrieval and viewing.

[0038] It should be noted that, for the SD card storage 8 in this embodiment, when the staff needs to monitor the mold production process offline, the staff can read the data stored in the SD card storage 8 through a PC computer, and the PC computer will display the data exported from the SD card storage 8 in the local program (client). The local program can process the data imported from the SD card storage 8 and present it to the operator in the form of real-time text or various curve display data.

[0039] It should be emphasized that when the mold production data visualization offline monitoring system of this embodiment monitors the mold production process, this embodiment simultaneously collects the temperature of the mold and the temperature of the hot runner 4; compared with the prior art, the monitoring data of the mold production data visualization offline monitoring system of this embodiment is more comprehensive.

[0040] In summary, through the above structural design, the mold production data visualization offline monitoring system of this embodiment can effectively monitor the mold temperature and hot runner 4 temperature in real time during the mold production process, and can also realize offline monitoring function. Therefore, the mold production data visualization offline monitoring system of this embodiment has the advantages of novel structural design and diverse functions.

[0041] Example 2, as Figure 1 As shown, the difference between this embodiment two and embodiment one is that: the upper template 1 and the lower template 2 respectively have first temperature measuring holes 10 for the mold temperature sensors 6, and each mold temperature sensor 6 is embedded in the corresponding first temperature measuring hole 10. Figure 1 As shown, the inner end of the first temperature measuring hole 10 extends into the upper template 1 and the lower template 2, and the first temperature measuring hole 10 is close to the temperature of the molding chamber 3, so as to detect the mold temperature more accurately.

[0042] Example 3, as Figure 1 As shown, the difference between this embodiment 3 and embodiment 1 is that: the upper template 1 and the lower template 2 respectively have a second temperature measuring hole 11 that is connected to the corresponding hot runner 4 for the corresponding hot runner temperature sensor 9, and each hot runner temperature sensor 9 is embedded in the corresponding second temperature measuring hole 11.

[0043] Example 4, as Figure 2 As shown, the difference between this embodiment four and embodiment one is that the mold production data visualization offline monitoring system also includes a communication unit 12, which is electrically connected to the MCU single-chip microcomputer 7.

[0044] It should be explained that the communication unit 12 in this embodiment is a common communication module. This communication module can realize real-time communication between the MCU microcontroller 7 and the PC computer. That is, the MCU microcontroller 7 can send the production data of the mold production process to the PC computer in real time through the communication module, so that the staff can view the production data of the mold production process in real time at the PC computer.

[0045] Example 5, such as Figure 2 As shown, the difference between Embodiment 5 and Embodiment 1 is that the mold production data visualization offline monitoring system further includes a power supply unit 13, which is electrically connected to the MCU microcontroller 7 to provide power to the mold production data visualization offline monitoring system. It should be noted that the power supply unit 13 in Embodiment 5 is a common power supply circuit, which will not be described in detail here.

[0046] Example 6, as Figure 2 As shown, the difference between this fifth embodiment and the first embodiment is that each mold temperature sensor 6 is electrically connected to the MCU microcontroller 7 through the mold temperature acquisition module 16, and each hot runner temperature sensor 9 is electrically connected to the MCU microcontroller 7 through the hot runner temperature acquisition module 17.

[0047] Example 7, as Figure 2 As shown, the difference between this embodiment seven and embodiment one is that the mold production data visualization offline monitoring system also includes a magnetic contact switch 14, a counting unit 15, and the magnetic contact switch 14, the counting unit 15, and the MCU microcontroller 7 are electrically connected in sequence.

[0048] The magnetic contact switch 14 has two states: open and closed. The open and closed states of the magnetic contact switch 14 are consistent with the opening and closing actions of the mold. That is, the magnetic contact switch 14 will be activated once for each mold opening and closing action.

[0049] It should be explained that the counting unit 15 in this embodiment is a common counting circuit, which will not be described in detail here.

[0050] When the mold production data visualization offline monitoring system of this embodiment 7 is working, the counting unit 15 counts the number of times the magnetic contact switch 14 is activated, and the counting unit 15 sends the counting data to the MCU microcontroller 7 in real time. The MCU microcontroller 7 then sends the above-mentioned counting data to the display screen 5 and the SD card memory 8. The display screen 5 displays the number of times the mold is opened and closed in real time, and the SD card memory 8 stores the mold opening and closing number information in real time.

[0051] Example 8 differs from Example 1 in that the mold temperature sensor 6 is a resistance temperature detector (RTD) sensor.

[0052] Example 9 differs from Example 1 in that the hot runner temperature sensor 9 is a thermocouple sensor.

[0053] Example 10 differs from Example 1 in that the MCU microcontroller 7 is model STM32F103RCT6.

[0054] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
