Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model hot runner controller;
Wherein: 1-PLC temperature controller, 2-resistance heat solid-state relay, 3-electrical current heat solid-state relay, 4-heavy-duty connector, 5-potential regulator, 11-temperature-sensitive input interface, 12-temperature control output interface, 13-220V voltage input interface, 41-voltage input interface, 42-mold temperature feedback interface.
Detailed description of the invention
Below in conjunction with drawings and Examples to the technical solution of the utility model carry out clear, describe in detail, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of hot runner controller, comprise PLC temperature controller 1, described PLC temperature controller 1 side is provided with temperature-sensitive input interface 11, temperature controls output interface 12 and 220V voltage input interface 13, described temperature-sensitive input interface 11 is connected with the mold temperature feedback interface 42 on heavy-duty connector 4 by wire, realize mold temperature automatically to regulate, described temperature is controlled output interface 12 and is connected with two interfaces of electrical current heat solid-state relay 3 bottom by wire, described temperature controls output interface 12 controls electrical current heat solid-state relay 3 conducting by output signal, the top-right interface of described electrical current heat solid-state relay 3 is connected by wire one end with the voltage input interface 41 on heavy-duty connector 4, the other end of described voltage input interface 41 connects with 220V voltage negative pole, realize voltage and output to heavy-duty connector, described heavy-duty connector connects with mould (not shown), thus by Control of Voltage mold temperature, the upper left interface of described electrical current heat solid-state relay 3 is connected with the upper right side interface of resistance heat solid-state relay 2 by wire, the upper left side interface of described resistance heat solid-state relay 2 is connected with 220V positive polarity by wire, bottom two interface of solid-state 2 electrical equipment that continue of described resistance heat is connected with potential regulator 5 by wire, by regulating the size of potential regulator 5, the hot solid-state relay 2 of controlling resistance is output voltage steadily.
Further describe operation principle and the process of the utility model hot runner controller below:
