Description

Technical Field

[0001] The utility model belongs to the technical field of shoe-making and molding equipment, in particular to a cooling device for shoe-making and molding equipment. Background Art

[0002] The production of rubber soles is mainly carried out by injection molding. During production, in order to increase production capacity and facilitate molding, a cooling device is required for cooling.

[0003] In the Chinese utility model patent with the publication number CN217414793U, a rapid cooling device for molds used in the production of safety shoes is disclosed. The cooling liquid is pumped into the cavity, and the cooling liquid and the mold body are heated together to achieve the purpose of rapid cooling. The cooling liquid returns to the water tank through the U-shaped elbow, and the two stirring blades rotate to stir the cooling liquid in the water tank, thereby accelerating the heat dissipation of the cooling liquid in the water tank, recycling it, effectively improving the cooling speed after the mold is formed, and accelerating production efficiency. However, when cooling, the cooling device directly discharges the cooling water into the cavity and cools the multiple molding cavities in the mold in turn. However, the heat absorption capacity of the water that absorbs heat will decrease when it flows, and the cooling effect will also be weakened, which is not convenient for efficient cooling of multiple molding cavities. Moreover, the above device is not convenient for rapid heat dissipation of the cooling water that absorbs heat in the water tank. When the device continues to work and the cooling water is continuously recycled, the temperature of the cooling water will gradually rise, and correspondingly, its cooling effect will gradually decrease.

[0004] Therefore, it is urgent to improve the existing rapid cooling device for the mold used in the production of safety shoes, and provide a cooling device for the shoe molding equipment that can quickly dissipate heat. Utility Model Content

[0034] As a preferred embodiment, on the basis of the above structure, the air cooling component 9 further includes a hollow tube 91, an air supply head 92, an air pump 93, a three-way pipe 94 and a connecting pipe 95.

[0040] The working principle of the utility model is as follows:

[0041] When in use, firstly, a proper amount of cooling water is injected into the water tank 1 through the water injection port 12. During the sole molding production process through the multi-group molding mold assembly 2, the water pump 4 can be turned on to draw the cooling water from the inside of the water tank 1 through the water guide pipe 5 and send it to the rightmost cooling box 23 through the water delivery pipe 6. When the cooling water flows in the cooling box 23, it can flow along the "S"-shaped flow channel formed between the multiple guide plates 24, which can increase the time of the cooling water in the cooling box 23, facilitate the transfer and absorption of the heat of the mold body 21 through the aluminum heat conductive sheet 22, and as Figure 3 As shown, multiple groups of molding die assemblies 2 are connected by an "S"-shaped cooling pipe 3, and the lower half of the cooling pipe 3 is located in the cooling water at the bottom of the water tank 1.

[0042] When the cooling water is discharged from the drain port 232 of the leftmost cooling box 23, the discharged cooling water can impact the "*"-shaped water dividing plate 11, so that the water dividing plate 11 can rotate and have a dispersing effect on the water flow. At the same time, the air pump 93 is turned on to deliver the cold air to the two hollow tubes 91 through the three-way pipe 94 and the connecting pipe 95. The dispersed water flow can be cooled by air using the multiple air supply heads 92 on the outer wall of the upper hollow tube 91, and the cooling water accumulated at the bottom of the water tank 1 can also be cooled. Moreover, the heat absorbed by the cooling water in the water tank 1 can be conducted out of the water tank 1 through the heat conducting plate 7 and the heat dissipating aluminum plate 8. At the same time, the heat dissipating aluminum plate 8 can be continuously cooled by air using the multiple air supply heads 92 on the outer wall of the lower hollow tube 91, which can accelerate the heat dissipation.

[0043] In summary, compared with the comparative documents, the cooling water in the present device can be cooled before entering each group of molding mold assemblies 2, which is convenient for efficient cooling of multiple groups of molding mold assemblies 2, and the recycled cooling water can be subjected to multiple heat conduction cooling in the water tank 1, so that the device can also perform stable cooling and heat dissipation during long-term operation.

[0044] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
