Temperature sensor (accompanying drawing is not shown) and pressure sensor (accompanying drawing is not shown) is provided with in described mold base 1.
With the vacuum cooled mould of EPP profiled member to the vacuum cooled technique of EPP profiled member, comprise the following steps:
1) after prepared by EPP profiled member, the valve D19 of the valve A16 of steam off air inlet pipe 12, the valve E21 of communicating pipe 20 and vacuum-pumping tube 15, open the valve B17 of the water inlet pipe 13 and valve C18 of drainpipe 14 simultaneously, cooling water enters in the vaporium 5 of mold base 1, and entered by the core 11 that cover half 2 in mold base 1 and dynamic model 3 are set respectively in the die cavity 4 that formed between cover half 2 and dynamic model 3, and the product 10 in die cavity 4 is cooled;
2) after in the scope that the temperature of product 10 is reduced to 80 ~ 85 degrees Celsius, close the valve B17 of the water inlet pipe 13 and valve C18 of drainpipe 14, the valve D19 simultaneously opening vacuum-pumping tube 15 and the vacuum pumping pump be communicated with vacuum-pumping tube 15, extract out the cooling water in die cavity 4;
3) when in the scope that the air pressure in die cavity 4 is down to-40 ~-60 kPas, open the valve E21 of communicating pipe 20, air is communicated with in die cavity 4;
4) after the air pressure in die cavity 4 returns to normal pressure, again the valve E21 of communicating pipe 20 is closed, vacuum pumping pump is vacuumized in die cavity 4 again, water and air remaining in die cavity 4 is extracted out;
5) step 3) and step 4) is repeated, until the temperature of die cavity 4 is down in the scope of 70 ~ 80 degrees Celsius.
In described step 3), open the time of the valve E21 of communicating pipe 20 in the scope of 1 ~ 5 second.
In described step 5), repeat the number of times of step 3) and step 4) in the scope of 2 ~ 3 times.
When the utility model uses, first by cooling water by the cover half 2 in mold base 1, dynamic model 3 and cool respectively the product 10 in die cavity 4, in the scopes of 80 ~ 85 degrees Celsius, so that the demoulding of product 10; But there is a large amount of moisture on product now 10 surface, direct demold feeding not only can cause the moisture content of product 10 too high, the water in mold base 1 also can be caused to splash down in equipment bottom, not only can make to produce around equipment the corrosion that ponding causes device bottom parts, also can cause the waste of water resource; So need the water in mold base 1 to discharge, just can reduce the moisture content of product 10, if utilize the direct draining of the deadweight of water, then can discharge the most water in mold base 1, but product 10 still has water to remain, cause the moisture content of product still cannot be up to standard, and the speed of draining slowly;
If directly utilize vacuum pumping pump to draw water in mold base 1, on the one hand, power due to pump is certain, after reaching certain negative pressure in mold base 1, pump just cannot reduce the pressure in mold base 1 more further, even if cause now proceeding for a long time to take out the air in mold base 1, the efficiency that the water on product 10 is drawn out of also extreme difference even directly cannot be drawn out of; On the other hand, because the reason of negative pressure in mold base 1, the contact surface of product 10 and cover half 2, dynamic model 3 is by adsorbed close, cause the core 11 of cover half 2 and dynamic model 3 blocked, the moisture content of product 10 self cannot be discharged, cause product 10 moisture content generally in the scope of 10 ~ 25%, still cannot reach the standard of moisture content; And product 10 and cover half 2 and dynamic model 3 are also unfavorable for the demoulding of product 10 after combining closely.
First by vacuum pumping pump, the water in mold base 1 is extracted out, and make the air pressure in mold base 1 be down in the scope of-40 ~-60 kPas, now the valve E21 of communicating pipe 20 is opened, in mold base 1, temporal pressure rises to atmospheric pressure state, air pressure gives product 10 1 thrusts originally fitted tightly with cover half 2, dynamic model 3, product 10 is separated with cover half 2, dynamic model 3, now core 11 also normally can be communicated with vaporium 5 and die cavity 4, under the effect of vacuum pumping pump, the moisture in mold base 1 continues to be drawn out of under the circulation of air; Again closed by the valve E21 of communicating pipe 20, the water in mold base 1 continues to extract out further by vacuum pumping pump; After in the scope that the air pressure in mold base 1 reaches-40 ~-60 kPas again, repeat to open the valve E21 of communicating pipe 20 and the step of the valve E21 of closedown communicating pipe 20, until the temperature of die cavity 4 is down in the scope of 70 ~ 80 degrees Celsius; Now the moisture content of product is in the scope of 5 ~ 8%, and the whole course of work only can need complete in the scope of 25 ~ 40 seconds.
By the effect of this process for cooling, not only in the process of product 10 being carried out to extraction moisture, cooling effect is served to product 10, but also effectively can reduce the moisture content of product 10; Product 10 repeatedly switches under negative pressure state and atmospheric pressure state simultaneously, and product 10 in cooling procedure, can be utilized the effect of pressure to make its demoulding, improve the demoulding efficiency of product 10; In addition, the time needed for whole process is shorter relative to other method, improves production efficiency, reduces the energy consumption of vacuum pumping pump.
