Description

Technical Field

[0002] The foaming mold is to fill the foaming resin directly into the mold, so that it is heated and melted to form a gas-liquid saturated solution. Through the nucleation effect, a large number of tiny bubble nuclei are formed, and the bubble nuclei grow to make foam plastic parts. After the foaming is completed, the mold itself is generally cooled delicately to make the finished product finalized, but the cooling time is long, which reduces the efficiency of the finished product production.

[0047] Working principle: before use, add water into the heating barrel 9 and the water tank 2. The water in the heating barrel 9 cannot exceed the height of the air inlet pipe 14. When in use, first start the motor 27 to drive the threaded column 2701 to rotate, so as to move the baffle door 8 away, then open the upper template 19, place the raw material on the inner side of the lower template 18, and then close the upper template 19 to fix it by rotating the vertical clamping plate 501, and then close the baffle door 8. At this time, start the electric heating base 901 to heat the water in the heating barrel 9. After heating, a large amount of hot steam is generated.

A large amount of hot steam will enter the heating part 15 through the air inlet pipe 14 to heat the mold body evenly, so that the raw material inside is heated and melted to form a gas-liquid saturated solution.

When the water in the cooling part 16 submerges the mold body, the water pump 12 on the other side will start to pump the water back to the water tank 2 to realize the water circulation, so that the mold body is cooled evenly and The temperature can be reduced quickly. When the required cooling time is reached, the water can be pumped back to the water tank 2 to pause. At this time, the motor 4 is started to drive the mold body back to its position, and the finished product can be taken out by opening the upper template 19, which effectively improves the efficiency of finished product production.
