Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding cooling water recycling, and specifically relates to a cooling device for accelerating the recycling of injection molding cooling water. Background Art

[0002] In modern industrial production, the injection molding process is widely used in manufacturing various plastic products. During the injection molding process, the mold needs to be cooled by cooling water to ensure the quality and production efficiency of plastic products. In order to save water resources and reduce production costs, the recycling of injection molding cooling water has become an important link.

[0003] A Chinese patent with the publication number: CN217573956U (application number: CN202221261557.7) discloses a cooling water recycling device for injection molding process, including a cooling water recycling tank. It is characterized in that a filter layer, a cooling layer and a water storage layer are sequentially arranged in the cooling water recycling tank from top to bottom. A separation tank is arranged in the filter layer. The upper part of the separation tank is sealed with the inner wall of the upper part of the filter layer, and the bottom of the separation tank is sealed with the inner wall of the lower part of the filter layer. The output shaft of the motor penetrates through the upper part of the cooling water recycling tank and is connected with the upper part of the stirring rod. A group of evenly distributed shaft sleeves are arranged on the stirring rod. Stirring paddles are arranged on both sides of the shaft sleeve. Scrapers are arranged on the stirring paddles. The scrapers are close to the inner wall of the separation tank. A water return pipe is arranged on the left side of the separation tank above the scraper. The water return pipe penetrates through the left part of the filter layer. A water return pump is arranged on the left side of the filter layer; This solution solves the problem of filtering and recycling the cooling water of the injection molding machine after recovery, but since its cooling layer uses a fan to introduce normal temperature air to exchange heat with the heated cooling water inside the heat exchange pipe, there is a problem of low heat exchange efficiency. Content of the Utility Model

[0004] In view of this, a cooling device for accelerating the recycling of injection molding cooling water provided by the utility model can solve the problem of low heat exchange efficiency of the current cooling water recycling device for injection molding process.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a cooling device for accelerating the recycling of injection molding cooling water, which includes a filtering box. The bottom end of the filtering box is connected to a heat exchange pipe inside a cooling box through a bottom leakage port, and the other end of the heat exchange pipe communicates with the top end of a water storage and collection box. Among them, ice storage bins are arranged on three side surfaces of the periphery of the cooling box. A partition is arranged between the ice storage bin and the cooling box, and through holes are evenly arranged on the partition. One end of the top of the ice storage bin is movably connected with a cover plate, an air inlet is opened in the middle of the cover plate, and a fan is arranged at a position corresponding to the air inlet on the cover plate. The bottom end of the ice storage bin is communicated with the water storage and collection box through a plurality of groups of inclined leakage channels. A support plate is arranged at the bottom end of the ice storage bin, and liquid leakage holes are evenly arranged on the support plate. An exhaust channel is arranged on one side of the periphery of the cooling box where the ice storage bin is not arranged.

[0007] The technical effects of the cooling device for accelerating the recycling of injection molding cooling water provided by the utility model are as follows: By arranging the ice storage bin for adding ice cubes inside, the external air flow is introduced into the ice storage bin through the fan on the cover plate. The air flow conducts heat with the ice cubes to form cold air, which enters the cooling box through the through holes on the partition and exchanges heat with the cooling water inside the heat exchange pipe. The water droplets formed after the ice cubes melt enter the inclined leakage channels through the liquid leakage holes at the bottom end and then flow into the water storage and collection box, improving the cooling efficiency of the cooling water after being heated, and replacing the original method of regularly supplementing water into the water storage and collection box.

[0008] On the basis of the above technical solution, the cooling device for accelerating the recycling of injection molding cooling water of the utility model can also be improved as follows:

[0009] Among them, the two ends of the through hole are respectively an air inlet end and an air outlet end, and the opening diameter of the air inlet end is larger than that of the air outlet end.

[0010] The beneficial effect of adopting the above improvement scheme is: By arranging the air inlet end and the air outlet end, a cold air acceleration channel is formed to reduce the temperature inside the cooling box and improve the cooling efficiency of the cooling water inside the heat exchange pipe after being heated.

[0011] Furthermore, an inclined through hole inner wall is formed between the air inlet end and the air outlet end, and a groove is opened at the bottom end of the through hole inner wall.

[0012] The beneficial effect of adopting the above improvement scheme is: By arranging the groove to guide the liquid droplets formed after the ice cubes melt, preventing the liquid droplets from entering the inside of the cooling box through the through hole.

[0013] Furthermore, support legs are arranged at the bottom of the support plate for contacting the bottom wall of the ice storage bin.

[0014] The beneficial effects of adopting the above improvement scheme are as follows: By setting a support plate to support the ice cubes and prevent them from falling into the inclined leakage channel and entering the water storage and collection tank, and by setting support legs to achieve a supporting effect.

[0015] Furthermore, ice cubes are placed inside the ice storage bin.

[0016] Furthermore, the number of the inclined leakage channels at the bottom end of one side of the ice storage bin is three groups.

[0017] Furthermore, the top end of the inclined leakage channel is a square opening, and the square opening is communicated with the bottom wall of the ice storage bin.

[0018] Furthermore, a support platform is formed between adjacent square openings.

[0019] Furthermore, the width of the support platform is one-tenth of the width of the square opening.

[0020] Furthermore, the inclination angle of the inner wall of the through hole is 15 - 30 degrees, and the length of the inner wall of the through hole is 1.5 times the diameter of the air inlet end.

[0021] The beneficial effects of adopting the above improvement scheme are as follows: By setting a larger inclination angle and cooperating with the groove to reduce the residence time of liquid droplets on the inner wall of the through hole, and by lengthening the length of the inner wall of the through hole, to prevent the liquid droplets from entering the cooling box under the influence of the air flow.

[0022] Compared with the prior art, the beneficial effects of a cooling device for accelerating the recycling of injection molding cooling water provided by the present utility model are as follows: By setting an ice storage bin for adding ice cubes inside, the external air flow is introduced into the ice storage bin through the fan on the cover plate. The air flow conducts heat with the ice cubes to form cold air, and enters the cooling box through the through holes on the partition plate to exchange heat with the cooling water inside the heat exchange tube. The water droplets formed after the ice cubes melt enter the inclined leakage channel through the liquid leakage holes at the bottom end and then flow into the water storage and collection tank, improving the cooling efficiency of the heated cooling water, and replacing the original way of regularly supplementing water into the water storage and collection tank; By setting an air inlet end and an air outlet end to form a cold air acceleration channel, reducing the temperature inside the cooling box and improving the cooling efficiency of the heated cooling water inside the heat exchange tube; By setting a larger inclination angle and cooperating with the groove to reduce the residence time of liquid droplets on the inner wall of the through hole, and by lengthening the length of the inner wall of the through hole, to prevent the liquid droplets from entering the cooling box under the influence of the air flow.
