Technical Field

[0001] The utility model relates to the technical field of EPS foam board processing, in particular to an EPS foam board processing cooling device. Background Art

[0002] EPS foam board, also known as expandable polystyrene board, has the advantages of light weight, low price, low thermal conductivity, low water absorption, good electrical insulation, sound insulation, shock resistance, moisture resistance, and simple molding process. Therefore, it is widely used as thermal insulation, sound insulation, and shock resistance materials for buildings, ships, automobiles, trains, refrigeration, and freezing. It is a polystyrene foam plastic board with a closed-cell structure made by pre-foaming expandable polystyrene beads and then heating and molding them in a mold. When processing EPS foam boards, a cooling device is required to cool the prepared EPS foam boards.

The utility model has a reasonable design and good practicality. After the lower mold and the upper mold are controlled to close the mold to heat and mold the EPS foam board, the molded EPS foam board can be directly cooled quickly and effectively, saving working time and improving work efficiency.

[0004] However, in the above technical scheme, after the EPS foam board is molded, the molded EPS foam board is cooled, and the upper mold and the lower mold can be demolded after cooling. During the molding of the EPS foam board, a large amount of water vapor will be generated inside the upper mold and the lower mold.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2As shown, an EPS foam board processing cooling device comprises a base 1, on which a lower mold 2 and a cooling water tank 3 are arranged, a first hydraulic rod 4 is arranged on one side above the lower mold 2, a lifting plate 5 is arranged on the outer wall on one side below the first hydraulic rod 4, a cooling mechanism 6 is arranged on the outer wall on one side below the lifting plate 5, an upper mold 7 is arranged on one side below the cooling mechanism 6, a plurality of water supply hoses 8 are arranged on one side of the cooling mechanism 6, a plurality of guide slide grooves 9 are arranged on the lifting plate 5, a guide slide column 10 is arranged in the guide slide groove 9, and a plurality of slide grooves 11 are arranged on the upper mold 7.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the cooling mechanism 6 is provided with a water cooling device 601 on the lifting plate 5, a water inlet 602 and a water outlet 603 are provided on one side of the water cooling device 601, and a fan 604 is provided on the outer wall of one side below the water cooling device 601;

[0025] The outer wall below the fan 604 is provided with a plurality of second hydraulic rods 605 and a plurality of sliding columns 606, a groove 607 is provided in the sliding column 606, a heat-conducting column 608 is provided in the groove 607, a plurality of ventilation holes 609 are provided on the inner wall of the groove 607, and a sealed heat-conducting plate 6010 is provided on the outer wall surface below the sliding column 606. When the formed foam board needs to be cooled, the water cooling device 601 and the fan 604 are first started, and the cooling water is circulated by using the water inlet 602, the water outlet 603, the water hose 8 and the cooling water tank 3, and then the second hydraulic rod 605 is started, and the second hydraulic rod 605 is used to cool the foam board. The pressure rod 605 moves the upper mold 7 a certain distance toward the direction approaching the fan 604, thereby separating the upper mold 7 from the lower mold 2 and releasing the seal of the upper mold 7 on the lower mold 2, so that the water vapor in the foam board can be discharged to the outside, and the sealed heat-conducting plate 6010 and the heat-conducting column 608 that are attached to the foam board transfer heat to cooperate with the water cooling equipment 601 to cool the foam board. At the same time, the fan 604 blows air into the groove 607, thereby accelerating the heat dissipation of the heat by the heat-conducting column 608, and then the wind in the groove 607 is blown to the foam board through a number of air holes 609, thereby accelerating the discharge speed of water vapor from the foam board.

[0026] The working principle of this EPS foam board processing cooling device:

[0027] When in use, first inject the raw material into the lower mold 2, then start the first hydraulic rod 4, and use the first hydraulic rod 4 to make the lifting plate 5 close to the lower mold 2, so that the lower mold 2 and the upper mold 7 fit each other, and then the EPS foam board forming operation can be carried out. After the EPS foam board is formed, start the water cooling device 601 and the fan 604, and use the water inlet 602, the water outlet 603, the water hose 8 and the cooling water tank 3 to circulate the cooling water, and then start the second hydraulic rod 605, and use the second hydraulic rod 605 to move the upper mold 7 a distance in the direction close to the fan 604, so that the upper mold 7 is separated from the lower mold 2, so that the water vapor at the foam board can be discharged to the outside, and use the seal that fits the foam board. The sealed heat-conducting plate 6010 and the heat-conducting column 608 transfer heat and cooperate with the water cooling device 601 to cool the foam board. At the same time, the fan 604 blows air into the groove 607 to accelerate the heat dissipation of the heat by the heat-conducting column 608. Then the wind in the groove 607 blows to the foam board through a number of ventilation holes 609, thereby accelerating the discharge rate of water vapor from the foam board. After cooling is completed, the water cooling device 601 and the fan 604 are turned off, and the upper mold 7 is returned to its original position through the second hydraulic rod 605. Then, the lifting plate 5 is returned to its original position through the first hydraulic rod 4, and the EPS foam board can be taken out from the lower mold 2. While the EPS foam board is being cooled, the water vapor on the EPS foam board can be quickly discharged.

It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
