Abstract
The utility model is related to a kind of shell core machine temperature control systems, including shell core machine, electric heating tube, PLC controller and temperature controller, temperature controller includes a warning output terminal for being used to be less than lower limit alarm in temperature, warning output terminal is electrically connected with the coil of an intermediate relay, and the normally opened contact of intermediate relay is electrically connected to the input terminal of the PLC controller.When temperature controller detects that the temperature of core box is less than lower limiting value, PLC controller receives the alarm signal that the temperature that temperature controller is sent out is less than lower limit；PLC controller waits for after receiving enabling signal, until alarm signal starts shell core machine after cancelling；Or PLC controller control shell core machine is shut down after circulation terminates at this.The utility model avoids shell core machine and is run when temperature is too low, more accurate to the temperature control of shell core machine, substantially increases the quality of sand core.
Description
Technical field
The utility model is related to shell core machine technical field more particularly to a kind of shell core machine temperature control systems.
Background technology
At present, the control mode of shell core machine is, after booting, by electrothermal tube heating core box, by temperature controller by temperature liter
To the temperature of requirement.
Such temperature control mode has a kind of drawback, when shell core machine is switched on, needs to observe temperature controller by operating personnel
For temperature to be confirmed whether to work, this mode is susceptible to the situation that temperature is not achieved technological requirement and works, and causes
The sand core produced is unqualified, so that influencing product quality.
Utility model content
Shell core machine can be avoided relatively low in core box temperature the technical problem to be solved by the utility model is to provide a kind of
In the case of the shell core machine temperature control system that starts.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of shell core machine temperature control system, including
Shell core machine, electric heating tube, PLC controller and temperature controller, the PLC controller for control the electric heater for heating and
The shell core machine is controlled to run；The temperature controller includes a warning output terminal for being used to be less than lower limit alarm in temperature,
The warning output terminal is electrically connected with the coil of an intermediate relay, and the normally opened contact of the intermediate relay is electrically connected to
The input terminal of the PLC controller.
As preferred technical solution, the temperature controller is Omron E5CZ-R2MT type temperature controllers.
By adopting the above-described technical solution, the beneficial effects of the utility model are：The utility model is by by temperature controller
The temperature sent out is less than the alarm signal of lower limit, when shell core machine is switched on, the temperature that the alarm signal cancels i.e. core box is waited for reach
To starting during job requirement；Or when shell core machine is run, shell core machine is controlled to shut down after this working cycles, avoid shell
Core machine is run when temperature is too low, more accurate to the temperature control of shell core machine, substantially increases the quality of sand core.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of the utility model embodiment.
Specific embodiment
As shown in Figure 1, a kind of shell core machine temperature control system, including shell core machine, electric heating tube, PLC controller and temperature control
Instrument, PLC controller are used to control electric heater for heating and control shell core machine operation；Temperature controller includes one and is used in temperature
Less than the warning output terminal 1 of lower limit alarm, warning output terminal 1 is electrically connected with the coil of an intermediate relay KA, in
Between relay KA normally opened contact electrical connection
To the input terminal I46 ends of the PLC controller.
Preferably, temperature controller is Omron E5CZ-R2MT type temperature controllers.
In this example, temperature controller is not limited to Omron E5CZ-R2MT type temperature controllers, in the market with same or similar work(
Energy temperature controller is suitable for the utility model, and fall and be within the protection scope of the utility model.
The operation principle of the utility model is：When shell core machine is switched on, electric heating tube heats core box, temperature controller inspection
The temperature of core box is surveyed, at a temperature of the temperature of core box is set less than temperature controller in limited time, is less than on temperature controller for output temperature
The warning output terminal 1 of lower limit alarm signal exports high level, the line of intermediate relay KA being electrically connected with warning output terminal 1
Enclose electric, the normally opened contact of intermediate relay KA is closed, and alarm signal is inputted by the input terminal I46 of PLC controller, passes through PLC
The internal processes control of controller, shell core machine, which receives enabling signal, to be started, and temperature controller is waited for detect the temperature liter of core box
Height is to operating temperature, and the output low level of warning output terminal 1, the coil losing electricity of intermediate relay KA, intermediate relay KA's is normal
Contact opening is opened, PLC controller control shell core machine normally starts；When shell core machine normal operation, temperature controller detects the temperature of core box
Degree is prescribed a time limit at a temperature of being set less than temperature controller, is less than the warning output end of lower limit alarm signal on temperature controller for output temperature
Son 1 exports high level, and the coil of intermediate relay KA being electrically connected with warning output terminal 1 obtains electric, and intermediate relay KA's is normal
Contact closure is opened, alarm signal is inputted by the input terminal I46 of PLC controller, is controlled by the internal processes of PLC controller, shell
Core machine is shut down after having run this working cycles, and temperature controller is waited for detect that the temperature of core box is increased to operating temperature, shell core machine
It is again started up.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
