Cooling water pressure is entered side cooling water channel 14 to the first cooling water channel 11 by force (forcing) pump 411 and gas blowing device 412 from first
Force feed, and gas is carried out by gas blowing device 412 and blowed, it is cold so as to which gas is entered into side cooling water channel 14 to first from first
But water route 11 supplies.In addition, being blowed by carrying out gas, the pressurization cooling water for making to enter the residual of side cooling water channel 14 first is done
It is dry.In addition, entering the pressurization cooling water of the supply of side cooling water channel 14 from first turns into cold water.
Enter the usual cooling water of side cooling water channel 15 in addition, being supplied to second by circulating tank to go out side pump 13p and second cold
But water return pump 18p driving (operating) is entered side cooling water channel 15 from second and supplied to the second cooling water channel 12.In addition, from
The two usual cooling waters for entering the supply of side cooling water channel 15 turn into cold water.
Then, by being supplied to the pressurization cooling water of the first cooling water channel 11 and being supplied to the usual of the second cooling water channel 12
Cooling water cools down mould 2.Moreover, the dissolving metal (aluminium) filled in mould is cooled down by cooled mould 2, dissolving
If metal (aluminium) solidifies, aluminum die-cast product is taken out from mould 2.Therefore, the pressurization for being fed into the first cooling water channel 11 is cold
But water and be fed into the usual cooling water of the second cooling water channel 12 by capture the heat of the dissolving metal transmitted from mould 2 and
By each cooling water from cool water heating into hot water.
Then, the pressurization cooling water of the first cooling water channel 11 is supplied to be discharged to going out side cooling water channel 16.Because
By from first enter side cooling water channel 14 constantly to the force feed of the first cooling water channel 11 come pressurization cooling water, by the cooling water that pressurizes
Discharged from the first cooling water channel 11 to side cooling water channel 16 is gone out.In addition, from the first cooling water channel 11 discharge pressurization cooling water into
For hot water.
Then, discharged to the pressurization cooling water for going out the discharge of side cooling water channel 16 to pans 5.It is discharged to pans 5
Pressurization cooling water during untill the water of pans 5 reaches " operation start water level ", be stored in into atmosphere opening
Between tank 5.In addition, being discharged to out the pressurization cooling water of side cooling water channel 16 turns into hot water.
Then, when the water in pans 5 reaches " operation start water level ", the fortune that the first cooling water returns to pump 17p is started
Turn, the cooling water W stored in pans 5 returns to water route 17 via the first cooling water and returned from pans 5 to cooling water circulation tank 3
Return.Moreover, cooling water W deoxidation is carried out by device for deoxidizing 31 in cooling water circulation tank.In addition, the water in pans reaches
When " operating stopping water level ", stop the operating that the first cooling water returns to pump 17p.In addition, from pans 5 to cooling water circulation tank 3
The cooling water W of return turns into hot water.
In addition, the usual cooling water for being supplied to the second cooling water channel 12 returns to pump 18p driving (fortune by the second cooling water
Turn), return to water route 18 via the second cooling water and returned from the second cooling water channel 12 to cooling water circulation tank 3.Moreover, in cooling water
The deoxidation of usual cooling water is carried out in circulating tank by device for deoxidizing 31.In addition, discharged from the second cooling water channel 12 usual cold
But water turns into hot water.
So, when mould cools down, made by pressue device main body 4a and each pump 13p, 17p, 18p in cooling water circulation tank
The cooling water W stored in 3 flows in each cooling water channel 11~18.Thus mould 2 is cooled down.
" intermittent running control action "
Fig. 3 is the time for representing to return the intermittent running example of pump motor corresponding to the first cooling water of the water of pans
Figure.Hereinafter, pump motor intermittent running control action is returned to the first cooling water based on Fig. 3 to illustrate.
In moment t0, the water of pans reaches " the operating stopping water that the operating for making the first cooling water return to pump 17p stops
Position ", so cooling water circulation drive control device 7, which makes the first cooling water return to pump motor 17m, stops (ON), make the first cooling water
The operating for returning to pump 17p stops.Thus, the cooling water W stored in pans 5 does not return from pans 5 to cooling water circulation tank 3
Return.
During moment t0~moment t1, i.e. the water of pans 5 stops from making the first cooling water return to pump 17p operating
" operating stopping water level " reach untill " the operation start water level " that starts the operating that the first cooling water returns to pump 17p during,
Cooling water circulation drive control device 7 does not make the first cooling water return to pump motor 17m drivings (ON).Thus, during which, in pans
The cooling water W stored in 5 does not return from pans 5 to cooling water circulation tank 3.Therefore, by being discharged from the first cooling water channel 11
Pressurization cooling water pans S water is increased.
In moment t1, the water of pans 5 reaches " operation start water level ".Now, cooling water circulation drive control device 7 makes
First cooling water returns to pump motor 17m drivings (ON), starts the operating that the first cooling water returns to pump 17p.Thus, in moment t1
During~moment t2, the cooling water W stored in pans 5 returns from pans 5 to cooling water circulation tank 3.Therefore, pans
5 water reduces.
In moment t2, the water of pans 5 reaches " operating stopping water level ".Now, cooling water circulation drive control device 7 makes
First cooling water returns to pump motor 17m and stops (OFF), the first cooling water is returned to pump 17p operating and stops.Therefore, from when
Carve t2 to rise, the water of pans 5 is increased by the pressurization cooling water discharged from the first cooling water channel 11.
So, cooling water circulation drive control device 7 controls the first cooling water to return according to the water intermittent running of pans 5
Pump motor 17m driving (ON)/stopping (OFF), the first cooling water is set to return to pump 17p intermittent runnings.Therefore, from the first cooling
The pressurization cooling water that water route 11 is discharged is temporarily to the pans storage to atmosphere opening.Thus, it is cold in pans 5 from being stored in
But water W gas bleedings.
" characteristic action of the cooling device of mould "
For example, by cooling water with by pressurized gas supply source (pressue device) supply one mould inside in the same direction of gas-pressurized
The cooling devices such as the die casting of (cooling water channel) supply are set to comparative example.In addition, generally, the oxygen concentration of cooling water is higher,
More got rusty easily in the pipe arrangement of cooling water, so relative to the cooling water for being supplied to cooling water channel, deoxidation is carried out by device for deoxidizing.
But the cooling device of die casting according to comparative example etc., the cooling water of cooling water channel is supplied to by pressurizeing
The gas flow of unit feeding improves oxygen concentration, so if cooling water returns to device for deoxidizing in this case, has deoxidation effect
The problem of fruit is deteriorated.
On the other hand, using following composition, i.e. cooled down by the pressurization cooling water that pressue device main body 41 is pressurizeed to first
The force feed of water route 11, and gas is supplied to the first cooling water channel 11, exist from the pressurization cooling water of the first cooling water channel 11 discharge
Stored into the pans 5 of atmosphere opening, return to pump 17p by the first cooling water makes via the first cooling water return water route 17
The cooling water W stored in pans 5 returns to the cooling water circulation tank 3 (Fig. 1 and Fig. 2) with device for deoxidizing 31.
That is, be supplied to the pressurization cooling water of the first cooling water channel 11 is made with the gas flow supplied by pressue device main body 41
Oxygen concentration improves.Therefore, the pressurization cooling water is before cooling water circulation tank 3 is returned, temporarily to the pans 5 to atmosphere opening
Storage.Thus, from cooling water W gas bleedings, so the oxygen concentration improved declines.
As a result, the situation that the deoxidation effect for the device for deoxidizing 31 that can suppress to be provided with cooling water circulation tank 3 is deteriorated.
" other characteristic actions of the cooling device of mould "
Following composition is used in embodiment 1, i.e. goes out side pump 13p driving by circulating tank, it is cold to enter side via second
But water route 15 supplies usual cooling water from cooling water circulation tank 3 to the second cooling water channel 12, and pump is returned by the second cooling water
18p driving, returning to water route 18 via the second cooling water makes the usual cooling water from the discharge of the second cooling water channel 12 return to cooling
Water circulation tank 3 (Fig. 1 and Fig. 2).
That is, pressurizeed to the not pressurized apparatus main body 41 of usual cooling water that the second cooling water channel 12 supplies.Therefore, to second
The usual cooling water that cooling water channel 12 supplies oxygen concentration unlike the pressurization cooling water supplied to the first cooling water channel 11 increases
Add.
Therefore, the deoxidation effect of the device for deoxidizing 31 to being provided with cooling water circulation tank 3 does not have an impact, can be by generally
Cooling water supplies to the second cooling water channel 12.
Moreover, by the usual cooling water supplied to the second cooling water channel 12, can aid in supplying to the first cooling water channel 11
Cooling effect of the pressurization cooling water given to mould 2.
Following composition is employed in embodiment 1, i.e. if the water (fortune of cooling water W as defined in being stored in pans 5
Turn to start water level), then pump 17p driving is returned to by the first cooling water, returning to pump 17p via the first cooling water makes in pans
The cooling water W of 5 storages returns to cooling water circulation tank 3 (Fig. 1~Fig. 3).
That is, cooling water W is stored in pans 5, untill cooling water W water as defined in being stored in pans 5.
Cooling water W therefore, it is possible to be stored from from the pans 5 to atmosphere opening is reliably evacuated.
Following composition is used in embodiment 1, i.e. is made according to the cooling water W detected by level sensor 51 water
First cooling water returns to pump 17p intermittent runnings, and the cooling water W for making to store in pans 5 returns to the (Fig. 1~figure of cooling water circulation tank 3
3)。
