Problems solved by technology

[0003] The current method is low in integration level, resulting in a huge size of the entire control box, complicated wiring, and inconvenient troubleshooting when problems occur; The improvement and volume increase often require dozens of temperature loops and dozens or even hundreds of voltage loops to control; the third and most important thing is that the linkage between the loops cannot be related, such as overheating or overheating of A. Fourth, there is no IoT function such as remote monitoring and error alarm recording log, which is equivalent to offline operation, which is not conducive to safety monitoring production

Embodiment 1

[0041] as attached figure 1 As shown, the intelligent hot runner temperature control system includes a power supply circuit 6, which can obtain the power required by the system from the mains, preferably an AC110-220V switching power supply circuit for the whole machine.

[0042] The main control board 7 obtains power from the power supply circuit 6 to perform control.

[0043] Different from the traditional nixie tube display, this system is equipped with a touch screen 5. In order to control better, the touch screen is preferably a 10-inch serial port touch screen. The touch screen can be selected as China Taiwan Weilun touch screen.

[0044] An isolated RS232 communication line is used between the main control board 7 and the touch screen 5, and data communication is performed through the Modbus communication protocol.

[0045] The main control board 7 uses an isolated CAN communication line to communicate with the temperature control board 8 and the voltage control board...

Embodiment 2

[0049] On the basis of the first embodiment, the main control board 7 of the system is provided with a pulse detection circuit 12, and the pulse detection circuit is used to detect whether there is a pulse of the injection molding machine 13 to determine whether the injection molding machine is offline.

[0050] The main control board 7 is also provided with a thermocouple acquisition circuit 14, and the thermocouple acquisition circuit collects the temperature of the mold through the thermocouple 15 to monitor the production environment, thereby realizing safe production.

[0051] The main control board 7 is also provided with a first program-controlled circuit 19 connected to an external alarm 16, which is used to warn the on-site production operators of dangerous signals (such as abnormal mold temperature, offline injection molding machine, etc.). The main control board 7 is connected to the temperature control board and the voltage control board through the first program co...

Embodiment 3

[0056] On the basis of the above two embodiments, the main control board can perform associated linkage control of each circuit according to the configuration of the touch screen by analyzing the information of each temperature / voltage control board. At present, there is no prior art about linkage control for controlling the temperature of molds in a large range (such as higher than 4 channels). Even on the same temperature control board, such as the two / four-way temperature control board mentioned above, multiple temperature controls are integrated into one control board, which is still an independent control in essence.

[0057] The specific method of temperature control is as follows:

[0058] After starting up, the main control board controls the storage circuit to read the system configuration of the default / last shutdown;

[0059] The main control board detects the number of circuits of the temperature control board and the voltage control board connected to the main co...

Abstract

The invention relates to an intelligent hot runner temperature control method and a temperature control system. The method includes: a main control board controls the storage circuit to read the default / last system configuration when it was shut down; the main control board detects the system configuration connected to the The number of channels of the temperature control board and the voltage control board of the main control board is displayed on the touch screen; the control parameters set on the touch screen are the default of the above channels / the control parameters when the last shutdown; the user is responsible for all The parameters of the number of temperature circuits and the number of voltage circuits are modified and checked to make them conform to the upcoming injection molding process; the modification and checking are specifically: the main control board is set with associated control rules, and the parameters of the associated control rules are input; The main control board performs associated control on temperature and voltage according to the associated control rules selected by the user, so as to achieve overall optimal control.

Description

technical field [0001] The invention relates to a temperature control system, in particular to an intelligent hot runner temperature control system used in the field of industrial injection molds. Background technique [0002] At present, the temperature control of industrial injection molds uses multiple independent meters with digital tube indication to control the temperature or voltage. When there are many temperature and voltage control channels, key settings need to be made for each control module. Moreover, each meter is in the state of working independently, and each meter needs to be set. In the prior art, there are gradually multi-channel control heads, such as our patents CN 2014208619937, CN 2014208622018, etc. The way these multi-channels are based is that one control head controls two to four channels of temperature or voltage, and the control heads are independent. [0003] The current method is low in integration level, resulting in a huge size of the enti...
