Technical Field

[0001] The utility model relates to the technical field of foam production and processing, in particular to a vacuum cooling device for a foam molding machine. Background Technique

[0002] In the production process of traditional foam molding machines, products need to be cooled for a certain period of time after molding to reach the required hardness and stability.

[0003] Referring to the "vacuum suction device for cooling the mold of a foam molding machine" with the authorized announcement number CN 210880554 U, it has the advantages of reasonable structure and simple operation. Through the operation of the motor, continuous negative pressure is generated in the installation box, and then the water vapor in the cooling and shaping device can be quickly sucked out, reducing the humidity of the finished product and shortening the later drying time of the finished product. It solves the problem that most of the current molding molds are cooled by water, but the existing cooling method cannot timely extract the moisture and heat in the mold, which easily increases the humidity of the finished product and leads to a long later drying cycle.

[0004] The utility model provides another solution to solve the above problems. Content of the Utility Model

The cooling component is arranged on the base and connected to the tank body. A pressure relief pipe is fixedly installed on the top of the tank body, and a pressure relief valve is fixedly installed on the pressure relief pipe.

[0008] The further setting of the utility model is: the cooling component includes a refrigerator, an air extraction pipe and a delivery pipe.

The refrigerator is connected with the delivery pipe and the air extraction pipe, and both the delivery pipe and the air extraction pipe are communicated with the tank body.

[0009] By adopting the above technical solution, the cooling liquid in the tank can be refrigerated.

[0010] A further setting of the present utility model is that: two mesh plates are fixedly installed on the inner wall of the tank, the mesh plates are conical in shape, and the two mesh plates are symmetrically arranged.

[0011] By adopting the above technical solution, the hot air entering the tank can be blocked from quickly floating upward, so that the bubbles generated by the hot air can stay in the cooling liquid for a longer time, and thus the cooling effect can be greatly improved.

[0012] A further setting of the present utility model is that: the end of the delivery pipe far from the cooler extends into the tank and is arranged in a disc shape, and a plurality of through holes are formed in the delivery pipe and are arranged upward.

[0013] By adopting the above technical solution, the refrigerated cooling gas can be quickly transported and dispersed into the cooling liquid in the tank, so that the cooling effect on the cooling liquid can be greatly improved.

[0014] A further setting of the present utility model is that: a filter plate is fixedly installed on the inner wall of the collection box, and the filter plate is hemispherical in shape.

[0015] By adopting the above technical solution, the hot air extracted by the vacuum pump can be filtered, and the liquid generated in the hot air extracted by the vacuum pump can be intercepted and diverted, so that the liquid can converge in the collection box for collection.

[0016] A further setting of the present utility model is that: a drain pipe is fixedly installed on the front side of the collection box, and a control valve is fixedly installed on the drain pipe.

[0017] By adopting the above technical solution, it is convenient to discharge the liquid collected in the collection box.

[0018] A further setting of the present utility model is that: a guide plate is fixedly installed on the bottom inner wall of the collection box, and the top side of the guide plate is arranged in a state of being lower in the middle and higher around.

[0019] By adopting the above technical solution, the liquid in the collection box can be diverted, so that it can converge better to the inlet position of the discharge pipe.

[0020] A further setting of the present utility model is that: a one-way valve is fixedly installed on the second connecting pipe.

[0023] By adopting the above technical solution, the hot air conveyed to the tank body by the second connecting pipe can be quickly dispersed and discharged into the coolant, so that the cooling rate of the hot air can be improved.

[0024] A further setting of the utility model is that a left support plate and a right support plate are fixedly installed on the outer top of the collection box, and the first connecting pipe and the second connecting pipe are respectively fixedly connected to the left support plate and the right support plate.

At the same time, when the hot air passes through the collection box, the water vapor condensed under the negative pressure environment can be intercepted under the action of the filter plate, and the intercepted water vapor is converged into the collection box, so that the humidity of the finished product can be reduced, and the later drying time of the finished product can be reduced. The hot air is discharged into the coolant in the tank body under the action of the vacuum pump, the second connecting pipe and the exhaust pipe, so that the rapid cooling of the hot air can be realized, and when the pressure in the tank body is relatively large, the pressure is relieved through the pressure relief pipe, and the coolant in the tank body can be cooled under the action of the cooling component, which can not only reduce the temperature of the exhaust gas discharged to the external environment, but also avoid the pollution of the atmosphere or the working workshop environment caused by the direct discharge of the hot air to the external environment.

[0028] Through the conical net plate, the hot air entering the tank body can be blocked from quickly floating up, so that the bubbles generated by the hot air can stay in the coolant for a longer time, and thus the cooling effect can be greatly improved. At the same time, through the delivery pipe with one end in a disc shape, the cooled cooling gas can be quickly delivered and dispersed into the coolant in the tank body, so that the cooling effect on the coolant can be greatly improved. And through the hemispherical filter plate, the hot air extracted by the vacuum pump can be filtered, and the liquid generated in the hot air extracted by the vacuum pump can be intercepted and guided, so that the liquid can be converged in the collection box for collection. By arranging the exhaust pipe, the exhaust pipe can quickly disperse the hot air conveyed to the tank body by the second connecting pipe and discharge it into the coolant, so that the cooling rate of the hot air can be improved.

[0029] In summary, through the combined use of a vacuum pump, a cooling and shaping device, a collection box, a tank body, a base, a vacuum pump, and a cooling component, the present utility model solves the problem that in the prior art, when a foam molding machine cools and shapes a product, the hot air generated by the product is directly discharged into the external environment, which easily pollutes the external air or the air in the workshop. At the same time, it can effectively reduce the humidity of the finished product and effectively avoid the later drying time of the finished product. BRIEF DESCRIPTION OF THE DRAWINGS

The mesh plate 41 in the tank body 4 blocks the hot air entering the tank body 4 from quickly floating up, so that the bubbles generated by the hot air stay in the coolant for a longer time, and thus the cooling effect can be greatly improved. The exhaust pipe 52 in the tank body 4 quickly disperses the hot air conveyed by the second connecting pipe 51 into the coolant in the tank body 4, so as to improve the cooling rate of the hot air. The cooled gas is discharged through the pressure relief pipe 42 and the pressure relief valve 43, thus completing the cooling and shaping work of the foam product.
