One piece large-scale temperature control module is assembled rapidly by each component or element quick coupling, to meet the product of different shape and size
Temperature control demand.
Here, temperature element 7 may be configured as the temperature sensor of such as thermocouple, and directly contact is for blade forming
The top layer of material, and the accuracy in order to guarantee measurement, can be in the blade forming material of temperature element 7 preheated back to needs
Heat-insulating material is covered on the surface of material, is made when preventing the temperature of cooling-part 3 and electric heating element 5 to measurement leaf product temperature
At adverse effect.
The blade cures temperature control system is laid on the blade forming material for needing to preheat, to can not only realize mold
Side heating can also realize the heating of blade lumen side or cooling.Meanwhile the blade cures temperature control system can also be embedded in blade mould
In tool, the automatic temperature controlling for the blade forming material that the needs of die side preheat is realized.
Before blade perfusion, blade cures temperature control system can be routed on the blade forming material for needing to preheat, be
The guarantee blade cures temperature control system with type, it is preferable that cooling-part 3 and electric heating element 5 can be formed as
It is flexible, and flexible heat-insulating layer flexibility heat-conducting layer is respectively equipped in the two sides of cooling-part 3 and electric heating element 5.
The blade cures temperature control system of exemplary embodiment according to the present utility model is briefly described below with reference to Fig. 3
To execute the process of temperature actuated.
Start to execute and be heating and curing operation, starting electric heating element 5, according to certain rate of heat addition (for example, 20 DEG C/h) into
Row heating (step S1)；Product temperature is sensed by temperature element 7, and judges to measure temperature TIt surveysWhether more than the first preset temperature
T1(for example, 65 DEG C) (step S2)；
In step S2, if measurement temperature TIt surveysLess than or equal to the first preset temperature T1(for example, 65 DEG C) then continue to add
Heat.
In step S2, if measurement temperature TIt surveysMore than the first preset temperature T1, then product temperature is maintained at about 60-75
DEG C predetermined amount of time (for example, 8 hours), and start timing (step S21)；Next, it is determined that currently accumulative soaking time t is
No arrival predetermined amount of time t0(step S22), if soaking time t reaches (for example, being greater than or equal to) predetermined amount of time t0, then

T2(for example, 75 DEG C) (step S3), if measurement temperature TIt surveysMore than the second preset temperature T2(for example, 75 DEG C), it is determined that current temperature
Height is spent, starting cooling-part 3 executes cooling operation (step S31), then returns to step S2.Here, the second default temperature
Spend T2Greater than the first preset temperature T1。
After step s 3, judge to measure temperature TIt surveysWhether third preset temperature T is less than3(for example, 60 DEG C), to determine temperature
Degree whether too low (step S32).In step S32, if measurement temperature TIt surveysLess than third preset temperature T3(for example, 60 DEG C), then
Determine that Current Temperatures are too low, starting electric heating element 5 is heated (step S33), then return step S2, judges to measure temperature
TIt surveysMore than the first preset temperature T1.Here, third preset temperature T3Less than the first preset temperature T1.In step S32, if measurement
Temperature TIt surveysNot less than third preset temperature T3, then continue to monitor Current Temperatures (step S34) and return to step S2, judge to survey
Amount temperature TIt surveysMore than the first preset temperature T1。
Operations described above step and sequence and listed temperature value or time value are merely exemplary, the present invention
It is not limited thereto, aforesaid operations step, sequence and temperature value or time value can rationally be changed according to practical condition, with symbol
The requirement of symphysis production standard.
