Description

Technical Field

[0001] The invention relates to the technical field of casting cooling, in particular to a cooling device for aluminum alloy die castings. Background Art

[0002] Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, non-toxicity, easy recycling, excellent conductivity, heat transfer and corrosion resistance. It is widely used in the marine industry, chemical industry, aerospace, metal packaging, transportation and other fields. In the production process of aluminum alloy castings, the high-temperature aluminum alloy castings need to be quickly cooled to facilitate subsequent processing.

[0003] A cooling device for hardware die-castings is provided in a Chinese patent document with publication number CN215941463U, including a transport device, a mobile device, a cooling device, a lifting device and an air-drying device, wherein the transport device is vertically arranged on the ground, the mobile device is arranged on the transport device, the cooling device is arranged at the bottom of the mobile device, the lifting device is arranged at the bottom of the mobile device, and the air-drying device is arranged at the bottom of the mobile device, and water is sprayed from the cooling water outlet through a cooling nozzle to cool the hardware die-castings on the transport belt, and the lifting cylinder drives the lifting cylinder to move upward. The movable plate moves, and the movement of the ascending movable plate drives the two clamping cylinders to move. The two clamping cylinders work to drive the two clamping movable plates to move. The two clamping movable plates move to clamp the hardware die-castings after the cooling is completed, so that the air-drying device can air-dry and cool the hardware die-castings after the cooling is completed. The air-drying fan works to air-dry and cool the hardware die-castings on the two clamping movable plates. The air-drying limit block fixes the air-drying fan on the air-drying support plate to prevent the air-drying fan from falling off the hardware die-castings on the two clamping movable plates when air-drying and cooling.

[0004] When cooling the die casting, the above scheme uses multiple cooling nozzles to spray cooling water from the top of the metal die casting to cool its surface. Since the cooling nozzles are arranged above the die casting, water cooling can only cool the die casting from one direction, which may result in different cooling degrees of the upper and lower parts of the die casting, so that the cooling device cannot perform all-round cooling of the casting, resulting in low cooling efficiency. In addition, during the air-cooling and drying process, since the air-drying fan is arranged on one side of the die casting after clamping to perform air-drying operation on the die casting, and some water stains are attached to the surface of the die casting after water cooling, the air-drying efficiency of the die casting is low. Therefore, the present invention designs a cooling device for aluminum alloy die castings to solve the problems existing in the prior art. Summary of the invention

A dryer 6 is symmetrically fixedly installed on the inner wall of the other side of the cooling box 1. A through groove is opened in the middle of the bottom of the cooling box 1 and the inside of the other side of the bottom of the cooling box 1. The through groove is inclined. One end of the through groove is connected to the drain port 101. Through the through groove, water droplets dripping from the transmission rollers on the conveyor 4 can flow back to the inside of the water storage tank 9 through the through groove to avoid water droplets accumulating in the inside of the cooling box 1.

[0026] See also Figure 1In an embodiment of the present invention, the blowing assembly 7 includes: an insulation box 701 and an air pump 704. The insulation box 701 is fixedly installed on the other side of the top of the cooling box 1.

[0027] See also Figure 1-2 In an embodiment of the present invention: the circulation component 10 includes: a positioning block 1001 and a water pump 1003, two positioning blocks 1001 are provided, the two positioning blocks 1001 are fixedly installed at the upper end inside the water tank 9, a second filter plate 1002 is placed between the tops of the two positioning blocks 1001, the water pump 1003 is fixedly installed on the bottom wall of the bracket 8, the water inlet end of the water pump 1003 is fixedly connected to the inside of the lower end of one side of the water tank 9, and the water outlet end of the water pump 1003 is fixedly connected to one end of the first connecting pipe 202 through one side of the bracket 8. When the conveyor 4 transports the aluminum alloy die-castings that need water cooling treatment, the water pump 1003 is started to transport the cooling water treated inside the water tank 9 to the inside of the annular water pipe 2, and spray it out from twelve ring-shaped nozzles 201 to evenly cool the aluminum alloy die-castings. The sewage for heat exchange flows into the inside of the water tank 9 through the drain port 101 for treatment, and is then recycled by the water pump 1003, thereby reducing the waste of water resources.

[0028] See also Figure 1-2 In the embodiment of the present invention, the second filter plate 1002 is composed of an upper metal filter and a lower activated carbon filter. The metal filter is used to filter the large oxide particles in the sewage, and the activated carbon filter is used to filter the tiny oxide wastes, thereby improving the filtration effect of the sewage.

[0031] See also Figure 1 and Figure 3 In the embodiment of the present invention, a plurality of PVC curtains 13 are fixedly installed at equal intervals on the top of the other side of the cooling box 1, and the bottom of the PVC curtain 13 is close to the surface of the top of the conveyor 4. By setting the PVC curtain 13, when the dryer 6 dries the water stains on the surface of the aluminum alloy die casting after water cooling, the loss of the internal temperature of the other end of the cooling box 1 is reduced.

[0032] Working principle: When the power is turned on, the aluminum alloy die-casting to be cooled is placed on the surface of one end of the conveyor 4 during water cooling of the aluminum alloy die-casting. The conveyor 4 transports the aluminum alloy die-casting to be water cooled, and starts the water pump 1003. The water pump 1003 transports the treated cooling water inside the water storage tank 9 to the inside of the annular water pipe 2, and sprays it from twelve ring-shaped nozzles 201 to evenly cool the surrounding areas of the aluminum alloy die-casting. The sewage for heat exchange flows into the inside of the water storage tank 9 through the drain port 101, is filtered by the second filter plate 1002, and is recycled by the water pump 1003. During the recycling of the cooling water, the cooling water is blown out by the air cooling blower 11. Towards the outer wall of the water storage tank 9, and through the heat dissipation fins 901 on the outer wall of the water storage tank 9, the cooling speed of the cooling water inside the water storage tank 9 is further accelerated, so that the cooling water can be quickly circulated and used. After the water cooling of the casting is completed, under the continuous conveyance of the conveyor 4, by starting the air pump 704, the air heated on the other side of the cooling box 1 is sucked into the interior of the insulation box 701 by the air intake hood 702, and after the air is dried and filtered by the first filter plate 703, it is then transported to the inside of the annular air pipe 3 by the air outlet end of the air pump 704, and dry hot air is sprayed through the twelve blowing heads 301 to blow off some water stains on the surface of the aluminum alloy die casting, thereby accelerating the subsequent drying process of the aluminum alloy die casting surface by the subsequent dryer 6.
