Abstract

The utility model discloses a hot-runner temperature controller of a mold of an injection molding machine. The hot-runner temperature controller comprises an upper computer, a hot-runner controller with a bus communication function, and a control module of the hot-runner controller, wherein the control module of the hot-runner controller is used for controlling the temperature of a hot runner of the mold; and the hot-runner controller carries out communication with the upper computer by an RS485 interface. The hot-runner temperature controller disclosed by the utility model has the advantages that the control module is used for controlling the temperature of the hot runner of the mold, and the control module and the hot runner communicate by using a bus, so that the temperature control can be carried out in the upper computer.

Description

Injection machine mold hot flow temperature controller

Technical field

The utility model relates to the injection machine mould, particularly the temperature controller of mould.

Background technology

Injection machine mold hot flow temperature control at present has dual mode, a kind of is the thermal module control mold hot flow temperature that controller of plastic injection molding carries, this is that the defective of control model is that the scan period of temperature control module is identical with injection machine control, mostly be 100ms, it is 1/10 second promptly for the mold temperature Detection ﹠ Controling cycle, because of the position of heating tube in the mould and thermocouple very approaching, in the time of 100ms, hot flow path has the temperature rise in several years, cause mold temperature to be higher or lower than design temperature, mold temperature control difficulty.Another kind is free-standing hot flow path controller control mold hot flow temperature, the stand alone type hot flow path adopts controllable silicon phase shifting control technology, in a power frequency period, be decomposed into the conducting of 360 ° of control silicon controlleds, one minute inner control precision was 360*50, provide high control accuracy greatly with respect to the controller of plastic injection molding temperature control module, but the shortcoming of this kind hot flow path controller is to be provided with, monitoring, control mold temperature in injection machine control.

The utility model content

Technical problem to be solved in the utility model provides a kind of injection machine mold hot flow temperature controller, makes it can be provided with, monitor, control the mold hot flow temperature in supervisory controller.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

Injection machine mold hot flow temperature controller, the hot flow path controller, the hot flow path controller control module that comprise host computer, band bus communication function, the control module control mold hot flow temperature of hot flow path controller, hot flow path controller and upper machine carry out communication by the RS485 interface.

Compared with prior art, advantage of the present utility model is: with control module control mold hot flow temperature, use bus communication between the two, can carry out temperature controlling in host computer.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

The specific embodiment

Embodiment is further described the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, injection machine mold hot flow temperature controller comprises hot flow path controller 2, the hot flow path control module 1 of host computer 4, band bus communication function, and host computer 4 is connected by connection 3 with hot flow path controller 2 and controls.

Above-mentioned communication interface adopts the RS485 communication interface, host computer can connect 64 instrument at most, the communication of different hot flow path sections is sent different addresses by host computer and selected, its communication modes is differential mode, transmission range can reach 1000m, connecting mode is three-way three-wire system mode, to improve the reliability of transmission.

Above-mentioned communication interface uses the asynchronous serial communication interface, and interface level meets the regulation in the RS485 standard.Data format is 1 start bit, 8 bit data positions, 1 position of rest, the no parity check position.

Adopt photoelectricity to isolate between the control circuit of the communicating circuit of above-mentioned RS485 communication interface and hot flow path control module 1, communication interface and importation circuit are isolated, when certain on connection instrument damage or fault, can not have influence on other instrumentations like this.When damage of instrument communication part or host computer fault, still can pass through the instrument keyboard operation, measure normally and control.

Claims

1. injection machine mold hot flow temperature controller, it is characterized in that: the hot flow path controller, the hot flow path controller control module that comprise host computer, band bus communication function, the control module control mold hot flow temperature of hot flow path controller, hot flow path controller and upper machine carry out communication by the RS485 interface.
