Description

Technical Field

[0001] This utility model relates to the field of die-casting equipment technology, and more specifically, to a cold chamber die-casting machine for aluminum processing. Background Technology

[0002] In the aluminum processing industry, cold chamber die casting machines bear the heavy responsibility of injecting liquid aluminum or aluminum alloy materials into mold cavities under high pressure to form various complex, high-precision aluminum parts. With the rapid development of industry, the demand for aluminum parts is increasing day by day, which has made the performance and production efficiency of cold chamber die casting machines a focus of industry attention. Currently, existing aluminum processing cold chamber die casting machines face a thorny problem in actual operation: the removal of castings from the mold is extremely inconvenient. After die casting, due to unreasonable mold structure design, the fit between the casting and the mold cavity is too tight, and there is a lack of effective demolding assistance structure. This often requires workers to use additional tools and spend a lot of time and energy on manual demolding. Not only is the labor intensity extremely high, but the cumbersome demolding process also greatly prolongs the production cycle of individual products, reduces production efficiency, increases production costs, and the frequent downtime caused by demolding difficulties seriously affects the continuity of production, which is not conducive to large-scale, efficient industrial production. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a cold chamber die casting machine for aluminum processing, which has the advantage of being able to automatically demold the castings.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides a cold chamber die-casting machine for aluminum processing, comprising:

[0024] Top plate 1, with bracket 3 fixedly installed on the left side of the top of top plate 1;

[0025] The demolding mechanism is located inside the support 3;

[0026] The demolding mechanism includes a first cylinder 4, the output end of which is fixedly connected to the inside of the bracket 3. A moving mold 5 is fixedly installed on the right end of the first cylinder 4. A positioning rod 6 is movably connected inside the moving mold 5. A stationary mold 7 is fixedly connected to the right end of the outer surface of the positioning rod 6. The left side of the stationary mold 7 is in contact with the right side of the moving mold 5. A fixing plate 8 is fixedly installed on the left end of the positioning rod 6. The bottom end of the fixing plate 8 is fixedly connected to the top end of the top plate 1. A top block 9 is fixedly installed on the right side of the fixing plate 8. A fixing rod 10 is fixedly installed on the right side of the top block 9. A moving block 11 is movably connected to the outer surface of the fixing rod 10. A spring 12 is fixedly installed on the left side of the moving block 11. The left end of the spring 12 is fixedly connected to the outer surface of the output end of the first cylinder 4. A top rod 13 is fixedly connected inside the moving block 11. The outer surface of the top rod 13 is movably connected to the inside of the moving mold 5.

[0027] After the molten aluminum is formed inside the moving mold 5 and the stationary mold 7, the operator activates the first cylinder 4. The first cylinder 4 then drives the moving mold 5 to move to the left along the outer surface of the positioning rod 6. The casting will then move to the left along with the moving mold 5. Due to the design of the positioning rod 6, the moving mold 5 moves more stably, thus ensuring the accuracy and tightness of the mold closing between the moving mold 5 and the stationary mold 7. At the same time, the first cylinder 4 drives the moving block 11 and the ejector rod 13 to move to the left through the spring 12. When the moving block 11 comes into contact with the ejector block 9 during the movement, it will be blocked by the ejector block 9. At this time, the moving block 11 will stop moving, while the moving mold 5 will continue to move to the left under the drive of the first cylinder 4. During this process, the spring 12 will be stretched. Due to the elastic force of the spring 12, the moving block 11 will have a good reset effect. At the same time, the spring 12 will squeeze and push the casting inside the moving mold 5, causing the casting to separate from the interior of the moving mold 5, thereby automatically demolding the casting.

[0028] The bottom of the top plate 1 is fixedly installed with a base frame 2, and a guide plate 14 is fixedly installed in the center of the bottom of the top plate 1.

[0029] Due to the design of the base frame 2, it will provide good support for the top plate 1 as a whole, so that the top plate 1 can be placed stably on the ground. Since the guide plate 14 adopts an inclined design, when the casting is separated from the moving mold 5, it will fall into the interior of the guide plate 14 under the action of gravity. At this time, the guide plate 14 will guide the casting.

[0030] Among them, the right side of the stationary mold 7 is internally fixedly fitted with a conveying pipe 15, the conveying pipe 15 is provided with a feed port 16, and the inside of the conveying pipe 15 is movably fitted with a movable block 19.

[0031] Due to the design of the feed port 16, the operator can pour molten aluminum into the inside of the conveying pipe 15 through the feed port 16. Due to the design of the movable block 19, when the movable block 19 moves to the left along the inside of the conveying pipe 15, it can inject the molten aluminum inside the conveying pipe 15 into the space between the moving mold 5 and the stationary mold 7.

[0032] A fixing frame 17 is fixedly installed on the right side of the top of the top plate 1. A second cylinder 18 is fixedly sleeved inside the fixing frame 17. The output end of the second cylinder 18 is fixedly connected to the right side of the movable block 19.

[0033] When the second cylinder 18 is running, the movable block 19 will move left and right along the inside of the delivery pipe 15 under the drive of the second cylinder 18.

[0034] Among them, a water tank 20 is fixedly installed on the front of the guide plate 14, a heat-conducting copper pipe 21 is fixedly sleeved inside the water tank 20, a fin 22 is fixedly sleeved on the outer surface of the heat-conducting copper pipe 21, and the outer surface of the fin 22 is fixedly connected to the outer surface of the water tank 20.

[0035] When the casting falls into the guide plate 14, the guide plate 14 will gradually guide it into the water tank 20. At this time, the coolant inside the water tank 20 will quickly absorb the temperature of the casting to achieve the effect of rapid cooling of the casting. During this process, the temperature of the coolant will rise and conduct heat to the water tank 20. At this time, the heat-conducting copper pipe 21 will absorb the temperature on the water tank 20 and transfer it to the fins 22. Due to the design of the fins 22, the heat of the heat-conducting copper pipe 21 can be quickly dissipated by increasing the heat dissipation area, so as to achieve the effect of rapid cooling of the coolant and ensure the cooling effect of the coolant on the casting.

[0036] The water tank 20 has a support plate 23 fixedly installed on its outer surface, and a fan 24 is fixedly installed inside the support plate 23.

[0037] When the fan 24 is running, it blows air onto the fins 22, thereby increasing the airflow around the fins 22 and enhancing the heat dissipation efficiency of the fins 22.

[0038] Working principle and usage process of this utility model:

[0039] First, the operator activates the first cylinder 4. This cylinder 4 drives the moving mold 5 to move to the right along the outer surface of the positioning rod 6. The right side of the moving mold 5 then comes into contact with the left side of the stationary mold 7 during this movement, resulting in a closed mold state. Due to the design of the positioning rod 6, the closing of the moving mold 5 and stationary mold 7 is more precise. Next, the operator pours molten aluminum from the inlet 16 into the conveying pipe 15. After the aluminum is poured, the operator activates the second cylinder 18. This cylinder 18 drives the movable block 19 to move to the left along the inside of the conveying pipe 15. The molten aluminum inside the conveying pipe 15 is then squeezed and injected between the moving mold 5 and the stationary mold 7 by the movable block 19. After the molten aluminum cools between the moving mold 5 and the stationary mold 7, it solidifies. Then, the operator activates the first cylinder 4 again, which drives the moving mold 5 to move to the left. Due to the casting... If the casting is too tightly fitted to the inside of the moving mold 5, the casting will move to the left along with the moving mold 5. At the same time, the first cylinder 4 will drive the moving block 11 to move to the left along the outer surface of the fixed rod 10 through the spring 12. At this time, the four push rods 13 will move to the left under the drive of the moving block 11. When the left side of the moving block 11 contacts the right side of the top block 9 during the movement, it will be blocked by the top block 9, so that the moving block 11 as a whole cannot continue to move to the left. At this time, the first cylinder 4 will continue to drive the moving mold 5 and the casting to move to the left. At this time, the spring 12 will be in a stretched state. Due to the design of the spring 12, it will play a good restoring role for the moving block 11. During this process, the right end of the push rod 13 will squeeze and push the casting, thereby separating the casting from the inside of the moving mold 5. Then the casting will fall into the inside of the guide plate 14 under the action of gravity, thus realizing the function of automatically demolding the casting.

[0040] Due to the design of the guide plate 14, when the casting falls into the guide plate 14, it will slide down into the water tank 20 under the guide plate 14. At this time, the operator pours coolant into the water tank 20, which can quickly cool the casting so that it can be quickly processed in the next step. During this process, the temperature of the coolant will rise. The water tank 20 will absorb the temperature of the coolant and conduct it to the heat-conducting copper pipe 21. Due to the design of the heat-conducting copper pipe 21, it can quickly absorb the heat inside the water tank 20 and conduct it to the fins 22. Due to the design of the fins 22, the heat conducted by the heat-conducting copper pipe 21 can be quickly dissipated by increasing the heat dissipation area. Then the operator starts the fan 24. The fan 24 will blow air onto the fins 22. At this time, the airflow around the fins 22 will accelerate the airflow, thereby continuously removing the heat from the surface of the fins 22, thereby improving the heat dissipation efficiency of the fins 22, and further improving the cooling effect and efficiency of the casting.
