In summary, the problem of reduced demolding efficiency due to poor cooling effect is solved.

[0028] A water storage tank 11 is fixedly installed in the middle part of the top of the bottom plate 1 , an L-plate 12 is fixedly installed in the inner cavity of the water storage tank 11 , and a water pump 13 is fixedly installed on the top of the L-plate 12 .

[0029] Reference Figure 1 , Figure 2 , Figure 5 The water storage tank 11 facilitates the carrying of the coolant, and the structural design of the water pump 13 realizes the function of pressurizing the coolant, thereby allowing the coolant to be released quickly.

[0030] A water inlet pipe 14 is fixedly installed at the bottom of the water pump 13 , and a drain pipe 15 is fixedly installed at one side of the water pump 13 .

[0031] Reference Figure 1 , Figure 2 and Figure 5 The coolant is initially transported through the water inlet pipe 14 and the drain pipe 15.

[0032] A three-way joint 16 is fixedly installed at one end of the drainage pipe 15 , and a diversion hose 17 is fixedly installed on the top and one side of the three-way joint 16 .

[0033] Reference Figure 1 and Figure 2 The coolant is guided by the three-way joint 16 and the diverter hose 17, so that the cooling liquid is released to the area to be cooled.

[0034] A return pipe 18 is fixedly installed on one side of the water storage tank 11 , and a transparent window 19 is fixedly installed on one side of the front side of the water storage tank 11 .

[0035] Reference Figure 2 and Figure 5 The reflux pipe 18 is used to guide the coolant so that it can flow back for reuse. The transparent window 19 is used to observe the coolant capacity inside the water tank 11 in real time to avoid production interruptions or excessive mold temperature caused by insufficient coolant.

After being limited, the foam box material becomes a fixed shape, and the water pump 13 absorbs the coolant in the water storage tank 11 through the water inlet pipe 14 and pressurizes it. The coolant reaches the three-way joint 16 through the drainage pipe 15, and passes through the three-way joint 16 It enters the diverter hose 17, and enters the water storage chamber 6 and the liquid storage box 9 through the diverter hose 17. The inner wall of the molding cavity 8 is cooled by the coolant, and the molding upper mold 10 is cooled by the liquid storage box 9. At this time, the inner and outer walls of the foam box are cooled, and the cooled coolant is released back to the water storage tank 11 through the reflux pipe 18, forming a complete circulating water circuit, which cools the entire mold over and over again. After the foam box is cooled and formed, the cylinder 22 raises the upper mold through the telescopic rod 23, and the molding upper mold 10 is separated from the molding cavity 8, and the foam box can be taken out.
