S120 constantly updates coremaking according to the process data and solidifies adjusting parameter, and solidified according to updated coremaking
Adjusting parameter adjusts coremaking curing operation.
In the present embodiment, it can be determined according to the process data of acquisition and need to adjust coremaking in subsequent coremaking solidification process
Cure parameter.Wherein, process data include the temperature of core box interior, the pressure in blowing pipe channel and current curing time it is long
Degree, correspondingly, coremaking solidification adjusting parameter includes temperature adjusting parameter, pressure adjusting parameter and curing time adjusting parameter, from
And temperature adjusting parameter, pressure adjusting parameter and curing time adjusting parameter can be distinguished, and corresponding adjustment is for controlling
The heater of temperature in core box, each equipment for controlling the gas generator of pressure in core box and for controlling curing operation
Run duration.
For example, the temperature of the core box interior for acquisition, updates coremaking according to process data and solidifies adjusting parameter, comprising:
According to the temperature and preset temperature of core box interior, determination deviation temperature；According to offset temperature and the first predetermined deviation temperature, really
Determine temperature adjusting parameter, and solidifies adjusting parameter as updated coremaking.
Wherein it is possible to which multiple moment are arranged, and the multiple preset temperatures of setting are respectively corresponded, for each moment, Yi Jiyu
Each moment corresponding preset temperature, determines corresponding offset temperature of each moment.First predetermined deviation temperature can be pre- from one
Any one value chosen in the offset temperature range first set, the e.g. maximum value of the offset temperature range.When deviation temperature
Degree has been more than the first predetermined deviation temperature, that is, offset temperature determines core box interior except preset offset temperature range
It is too high or too low for temperature, it needs to be adjusted, and according to offset temperature and the first predetermined deviation temperature, temperature adjustment ginseng
Number solidifies adjusting parameter as updated coremaking.
In a specific example, it is based on following formula temperature adjusting parameter:
If (temperature > preset temperature of core box interior)
Temperature-preset temperature=offset temperature of then core box interior
If (offset temperature > the first predetermined deviation temperature)
The-the first predetermined deviation of then offset temperature temperature=temperature adjusting parameter
End if
Else if (temperature < preset temperature of core box interior)
Then preset temperature-core box interior temperature=offset temperature
If (offset temperature > the first predetermined deviation temperature)
The-the first predetermined deviation of then offset temperature temperature=temperature adjusting parameter
End if
End if
For another example, for the pressure in the blowing pipe channel of acquisition, coremaking is updated according to process data and solidifies adjusting parameter,

Curing time adjusting parameter=(default curing time length+deviation time length) * %
Else if (current curing time span < predetermined time period)
The current curing time span of then predetermined time period -=deviation time length
Curing time adjusting parameter=(default curing time length-deviation time length) * %
End if
End if
