Description

Technical Field

[0001] The present invention belongs to the technical field of cooling automobile die castings, and more specifically, relates to a cooling device for producing automobile die castings. Background Art

[0002] Die casting is a kind of pressure-cast parts. It uses a pressure casting machine equipped with a casting mold to pour heated liquid metals such as copper, zinc, aluminum or aluminum alloy into the inlet of the die casting machine. The die casting machine is die-cast to cast copper, zinc, aluminum or aluminum alloy parts of the shape and size restricted by the mold. Such parts are usually called die castings. In the automotive manufacturing industry, die castings are key components. Their quality and production efficiency directly affect the performance and production cost of the car. The cooling process is an important link in the production process of automotive die castings. It plays a decisive role in the internal structure, dimensional accuracy and surface quality of the die castings.

[0003] The current cooling devices for automotive die casting production still have some shortcomings: 1. Most automotive die-casting cooling devices use a single cooling method, such as spraying or air cooling. This makes it difficult to achieve uniform cooling of the upper and lower surfaces and various parts of the die-casting, and easily creates cooling dead corners, resulting in poor cooling effect of the die-casting and affecting the quality stability of automotive die-castings. 2. Traditional automotive die-casting cooling devices usually use static water spray cooling, which is difficult to cover the complex surface of the workpiece. Especially for die-castings with concave and convex structures, it is easy to produce cooling dead corners, resulting in workpiece deformation or stress concentration; 3. In the cooling process of automobile die-casting parts, the traditional automobile die-casting cooling device will cause the debris falling off the surface of the die-casting parts to enter the circulation system with the wastewater. If it is not cleaned in time, it may clog the pipes or damage the water pump, affecting the stability of the system. Therefore, in view of this, the existing structure and defects are studied and improved, and a cooling device for automobile die-casting production is provided, in order to achieve a more practical purpose.

A water pump 2 13 is installed at the upper end of the storage tank 11. A connecting pipe 14 is connected between the water pump 2 13 and the temporary storage tank 5 to transport the water in the temporary storage tank 5 to the storage tank 11, forming a complete water circulation system. The first swing arm 31 is arranged perpendicular to the frame 1, and the second swing arm 32 is arranged at an angle. A second gear 34 is fixedly mounted on each second rotating shaft 33, and a third gear 35 is fixedly mounted on the second rotating shaft 33 of the second swing arm 32. In the initial state, the first swing arm 31 is arranged perpendicularly and the second swing arm 32 is arranged at an angle, so that the automobile die-casting parts are not blocked during the transportation process, and the automobile die-casting parts can be smoothly transported into the cooling box 2. A slide rail 8 is fixedly mounted on the outer end of the cooling box 2, a rack 82 is slidably mounted on the upper end of the slide rail 8, a slider 83 is fixedly mounted on the middle part of the bottom end of the rack 82, a slide groove is provided on the upper surface of the slide rail 8, the slider 83 movably passes through the slide groove, an electric telescopic rod 81 is fixedly mounted on the bottom end of the slide rail 8, the telescopic rod of the electric telescopic rod 81 is fixedly connected to the slider 83, two gears 34 are engaged with the rack 82, the electric telescopic rod 81 is operated to control the reciprocating movement of the rack 82, and the reciprocating movement of the rack 82 drives the two gears 34 to rotate, thereby controlling the operation of the swing assembly 3, and the operation of the swing assembly 3 further controls the reciprocating movement of the automobile die-casting; A rotating shaft 26 is rotatably mounted on the cooling box 2, a gear 27 meshing with a gear 35 is fixedly mounted on the rotating shaft 26, a synchronous wheel 28 is fixedly mounted on both the rotating shaft 26 and the rotating shaft 3 63, and a synchronous belt 29 is sleeved on the two synchronous wheels 28; Fan three 44 and fan two 25 are staggered in the upper and lower positions. Fan two 25 is located above the conveying assembly 9 and is used to dry the upper surface of the automobile die-casting. Fan three 44 is installed at one end of the collection cover 4 to dry the bottom surface of the automobile die-casting to prevent rust and other problems caused by residual moisture in subsequent processes and ensure product quality.

[0037] The working principle of this embodiment is as follows: The first step is initial conveying and positioning: the automobile die-casting is placed on the circular shaft 92 of the conveying assembly 9, and the motor 96 is started. The motor 96 drives the driving shaft 93 to rotate. The two chains 91 are meshed with each other through the transmission. The circular shaft 92 is driven to move, and the automobile die-casting is smoothly conveyed into the cooling box 2. When one end of the automobile die-casting contacts the vertically arranged rocker 31, the conveying assembly 9 stops. At this time, the automobile die-casting is in the cooling station in the cooling box 2, ready for subsequent cooling operations. The second step is water spray cooling: water pump 12 is started. Under the action of water pump 12, the cold water in the storage tank 11 is transported to the two pipe groups 21 through the connecting pipe 23. Since the pipe groups 21 are evenly spaced with nozzles 22, the cold water is evenly sprayed from the nozzles 22, and the upper and lower surfaces of the automobile die-casting are sprayed with water to cool the automobile die-casting at the same time. At the same time, fan 1 24 on the upper side of the inner cavity of the cooling box 2 starts to operate. The airflow generated by fan 1 24 accelerates the evaporation of water, removes a large amount of heat, thereby enhancing the cooling effect and quickly reducing the temperature of the automobile die-casting. The third step is wastewater collection and preliminary filtration: Due to the gap between the adjacent circular shafts 92, the water sprayed by the nozzle 22 located below can be smoothly sprayed to the bottom surface of the automobile die-casting and fall into the collection cover 4 under the action of gravity. The bottom surface of the inner wall of the collection cover 4 is designed as a slope, and two guide plates 41 are fixedly installed at the port. This allows the collected water to enter the temporary storage box 5 from the water inlet 55 opened on the surface of the connecting shell 54 under the guidance of the guide plates 41. During this process, the arc-shaped filter screen 6 in the temporary storage box 5 performs preliminary filtration on the inflowing water, intercepting debris, impurities, etc. contained in the water to prevent them from entering the subsequent water circulation system; The fourth step is to reciprocate and strengthen the cooling of the die casting: start the electric telescopic rod 81, and the reciprocating movement of the telescopic rod drives the slider 83 to reciprocate in the slide groove on the slide rail 8, and the slider 83 then drives the rack 82 to reciprocate on the upper end of the slide rail 8. Since the two gears 34 are engaged with the rack 82, the reciprocating movement of the rack 82 drives the two gears 34 to rotate back and forth, so that the two rotating shafts 33 rotate back and forth accordingly. The rotating shaft 33 drives the rocker arm 1 31 and the rocker arm 2 32 to swing back and forth in the cooling box 2, thereby pushing the automobile die casting to reciprocate in the cooling box 2. This reciprocating movement allows various parts of the automobile die casting to be more fully cooled by the water spray from the nozzle 22, avoiding cooling dead corners and effectively improving the cooling effect. The fifth step is to clean the filter screen and stir and cool the wastewater: when the shaft 2 33 drives the pendulum rod 2 32 to swing back and forth, the gear 3 35 fixed thereon also rotates back and forth, and the gear 3 35 meshes with the gear 1 27, thereby driving the gear 1 27, the shaft 1 26 and the synchronous wheel 1 28 to rotate back and forth. Since the synchronous wheel 1 28 on the shaft 1 26 is connected to the synchronous wheel 1 28 on the shaft 3 63 through the synchronous belt 1 29, the rotation of the shaft 1 26 can be transmitted to the shaft 3 63, so that the shaft 3 63 rotates back and forth, and the rotation angle is greater than one hundred and eighty degrees. The rotation of the shaft 3 63 drives the scraper 62 with holes to swing back and forth on the surface of the curved filter screen 6, scraping off the debris attached to the curved filter screen 6, and the debris falls onto the material sorting plate 61 under the action of gravity. The slag is discharged from the slag discharge port 56 along the inclination direction of the material-sliding plate 61, thereby ensuring the filtering effect of the arc-shaped filter screen 6. At the same time, when the rotating shaft 3 63 rotates, the synchronous wheel 2 64 fixed thereon also rotates accordingly, and the synchronous wheel 3 72 is driven to rotate by the synchronous belt 2 73, thereby driving the stirring shaft 7 to rotate. The stirring blades 71 fixedly installed at equal intervals on the stirring shaft 7 rotate accordingly, stirring and mixing the water in the temporary storage box 5 to make the water temperature more uniform. The operation of the fan 4 52 in the rectangular frame 51 accelerates the air flow on the water surface, promotes water evaporation, and realizes the cooling of the water in the temporary storage box 5. The water pump 2 13 is started, and the cooled water in the temporary storage box 5 can be transported to the storage box 11 through the connecting pipe 14, thereby realizing the recycling of cooling water and saving water resources. Step 6: Wastewater heat dissipation: Several slow-flow plates 42 are fixedly installed at equal intervals on the bottom surface of the inner wall of the collection cover 4 to increase the flow path and residence time of the water in the collection cover 4, allowing the water more time to exchange heat with the outside world. Several heat dissipation fins 43 are fixedly installed at equal intervals on the bottom of the collection cover 4 to further increase the heat dissipation area, accelerate the heat dissipation of the water in the collection cover 4, reduce the wastewater temperature, and create favorable conditions for subsequent recycling; Step 7: Drying and unloading: After the automobile die-casting has finished cooling, the electric telescopic rod 81 drives the swing arm 1 31 to become inclined and the swing arm 2 32 to become vertical. At this time, the conveying assembly 9 is started, and the automobile die-casting is conveyed out of the cooling box 2 driven by the circular shaft 92. Since the swing arm 1 31 is in an inclined state, it will not hinder the conveying of the automobile die-casting. The automobile die-casting is first moved to above the fan 3 44 installed at one end of the collection cover 4. The fan 3 44 is running to dry the bottom surface of the automobile die-casting to remove residual moisture. Then, the automobile die-casting is moved to below the fan 2 25. The fan 2 25 is running to dry the upper surface of the automobile die-casting. In the eighth step, the rubber layer sleeved on the outside of the rocker arm 31, the rocker arm 32 and the circular shaft 92 can increase the friction between the circular shaft 92 and the die-casting to prevent sliding during transportation. When the rocker arm 31 and the rocker arm 32 push the die-casting to move back and forth, the rubber layer can buffer the force and prevent the surface of the die-casting from being scratched. At the same time, the elasticity of the rubber layer can also reduce the collision and wear of mechanical parts.
