Description

Technical Field

[0001] This utility model relates to the field of feeding mechanisms, and in particular to a feeding mechanism for a cold chamber die casting machine. Background Technology

[0002] Cold chamber die casting machines are commonly used equipment in metal die casting production. Their feeding mechanism is a key component for conveying molten metal into the die-casting mold cavity, directly affecting the efficiency, safety, and product quality of die casting production. A typical structure of the feeding mechanism in a cold chamber die casting machine usually includes a control unit, a drive actuator, and a material carrier. The control unit is often a control box, used to receive commands and coordinate the operation of various components. The drive actuator is generally a drive robotic arm, mounted on the control box, which can achieve multi-dimensional movement under control signals, such as rotation, extension, and oscillation. The material carrier is centered around a ladle, which is fixedly mounted on the output shaft of the drive robotic arm. Driven by the robotic arm, it completes the entire feeding process of scooping molten metal from the furnace and transferring it to the injection chamber of the die casting machine.

[0003] In actual production, the feeding ladle of a cold chamber die-casting machine often faces the problem of molten metal spillage when conveying high-temperature molten metal. This is because when the ladle follows the driven robotic arm for transfer and tilting actions, the molten metal shakes violently due to inertia, centrifugal force, and the impact during action transitions. Since traditional ladles lack effective blocking and buffering structures, the shaking molten metal easily overflows the edge of the ladle, causing spillage. This spillage not only wastes metal raw materials and increases production costs, but more seriously, the splashing of high-temperature molten metal can damage equipment parts, shorten equipment lifespan, and even pose a significant threat to the personal safety of operators. It also affects the continuity and stability of die-casting production. Utility Model Content

[0004] The main purpose of this utility model is to provide a feeding mechanism for a cold chamber die casting machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A feeding mechanism for a cold chamber die-casting machine includes a ladle. A main blocking and anti-splash buffer structure is fixedly installed inside the ladle. The main blocking and anti-splash buffer structure consists of a first blocking and anti-splash base plate and a mounting plate. Two mounting plates are symmetrically fixed at both ends of the first blocking and anti-splash base plate. Two auxiliary blocking and anti-splash buffer structures are symmetrically inserted into the first blocking and anti-splash base plate. The auxiliary blocking and anti-splash buffer structure consists of an insert strip, a limiting baffle, and a second blocking and anti-splash base plate. Two limiting baffles are symmetrically fixed at both ends of the insert strip. Two second blocking and anti-splash base plates are respectively fixed at the outer ends of the two limiting baffles.

[0007] Preferably, the ladle is fixedly mounted on the output shaft of the driving robotic arm, and the driving robotic arm is mounted on the control box.

[0008] Preferably, the mounting plate on the main splash-proof buffer structure is fixedly installed on the inner wall of the ladle.

[0009] Preferably, the upper end of the first splash-proof substrate on the main splash-proof buffer structure is provided with a plurality of mounting slots, and the first splash-proof substrate is provided with a plurality of first flow holes, the first flow holes penetrating the first splash-proof substrate.

[0010] Preferably, the insert strip on the auxiliary splash-proof buffer structure is inserted into the mounting slot opened at the upper end of the first splash-proof substrate, the two limiting baffles on the auxiliary splash-proof buffer structure are respectively located on both sides of the first splash-proof substrate, and the second splash-proof substrate is provided with a plurality of second flow holes.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By incorporating a main splash-proof buffer structure consisting of a first splash-proof base plate and a mounting plate inside the ladle, and an auxiliary splash-proof buffer structure consisting of an insert strip, a limiting baffle, and a second splash-proof base plate on the main splash-proof buffer structure, the problem of molten metal spillage caused by the lack of effective blocking and buffering structures when conveying high-temperature molten metal using traditional ladles can be effectively solved. The first splash-proof base plate in the main splash-proof buffer structure plays a major role in blocking the swaying molten metal, reducing its swaying amplitude. At the same time, the first flow hole allows some molten metal to flow slowly, avoiding excessive impact force due to complete blocking. The auxiliary splash-proof buffer structure is connected to the first splash-proof base plate via the insert strip and the mounting plate. The slot-mounted design allows for position adjustment based on actual needs. The second anti-splash substrate further enhances the blocking effect, while the second flow hole also serves as a buffer and diversion mechanism. Two limiting baffles ensure the auxiliary anti-splash buffer structure is stably installed on the first anti-splash substrate, preventing displacement under the impact of molten metal. This combined primary and secondary anti-splash buffer structure design significantly reduces spillage of molten metal during transfer and pouring, saving raw materials, reducing production costs, preventing damage to equipment components from high-temperature molten metal splashes, extending equipment lifespan, ensuring operator safety, maintaining the continuity and stability of die-casting production, and improving product quality.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a feeding mechanism for a cold chamber die-casting machine includes a ladle 3. A main anti-splash buffer structure 4 is fixedly installed inside the ladle 3. The main anti-splash buffer structure 4 consists of a first anti-splash base plate 6 and mounting plates 7. Two mounting plates 7 are symmetrically fixed at both ends of the first anti-splash base plate 6. Two auxiliary anti-splash buffer structures 5 are symmetrically inserted into the first anti-splash base plate 6. The auxiliary anti-splash buffer structure 5 consists of an insert strip 10, a limiting baffle 11, and a second anti-splash base plate 12. Two limiting baffles 11 are symmetrically fixed. The first blocking and splash-proof substrate 6 and the mounting plate 7 are fixedly installed at both ends of the insert strip 10. There are two second blocking and splash-proof substrates 12, which are respectively fixedly installed at the outer ends of the two limiting baffles 11. By setting a main blocking and splash-proof buffer structure 4 composed of the first blocking and splash-proof substrate 6 and the mounting plate 7 inside the ladle 3, and setting an auxiliary blocking and splash-proof buffer structure 5 composed of the insert strip 10, the limiting baffles 11 and the second blocking and splash-proof substrate 12 on the main blocking and splash-proof buffer structure 4, the problem of molten metal spillage caused by the lack of effective blocking and buffering structure when the traditional ladle is conveying high-temperature molten metal can be effectively solved. To address the leakage issue, the first anti-splash substrate 6 in the main anti-splash buffer structure 4 plays a primary role in blocking the sloshing molten metal, reducing its sloshing amplitude. Simultaneously, the first flow hole 9 allows some molten metal to flow slowly, preventing excessive impact from complete blockage. The auxiliary anti-splash buffer structure 5 is installed by inserting a strip 10 into the mounting slot 8 on the first anti-splash substrate 6, allowing for position adjustment according to actual needs. Its second anti-splash substrate 12 further enhances the blocking effect, and the second flow hole 13 also serves as a buffer and diversion mechanism. Two limiting baffles 11 ensure the auxiliary anti-splash buffer structure 5 is stably installed on the first anti-splash substrate 6, preventing displacement under the impact of molten metal. This combined main and auxiliary anti-splash buffer structure design significantly reduces spillage of molten metal during transfer and pouring, saving metal raw materials, reducing production costs, preventing damage to equipment components from high-temperature molten metal splashes, extending equipment lifespan, ensuring operator safety, maintaining the continuity and stability of die-casting production, and improving product quality.

[0020] Specifically, the ladle 3 is fixedly mounted on the output shaft of the driving robotic arm 2, which is mounted on the control box 1. The mounting plate 7 on the main blocking splash buffer structure 4 is fixedly mounted on the inner wall of the ladle 3. Several mounting slots 8 are evenly opened on the upper end of the first blocking splash buffer base plate 6 on the main blocking splash buffer structure 4. Several first flow holes 9 are also opened on the first blocking splash buffer base plate 6, through which the first flow holes 9 pass. The insert strip 10 on the auxiliary blocking splash buffer structure 5 is inserted into the first blocking splash buffer base plate 6. Inside the mounting slot 8 at the upper end of the substrate 6, two limiting baffles 11 on the auxiliary blocking and anti-splash buffer structure 5 are respectively located on both sides of the first blocking and anti-splash substrate 6. The second blocking and anti-splash substrate 12 has several second flow holes 13. In use, the control box 1 issues a command to start the drive robotic arm 2. The drive robotic arm 2 moves the ladle 3 to the furnace, allowing the ladle 3 to scoop up an appropriate amount of molten metal. Then, the drive robotic arm 2 moves again, moving the ladle 3 towards the injection chamber of the cold chamber die-casting machine. During this movement, when the molten metal in the ladle 3... When the liquid metal sloshes due to inertia, centrifugal force, or a change in motion, the first anti-splash substrate 6 in the main anti-splash buffer structure 4 plays a major role in blocking the sloshing liquid metal, reducing its sloshing amplitude, and preventing the liquid metal from directly impacting the edge of the ladle 3. Simultaneously, the first flow hole 9 on the first anti-splash substrate 6 allows some liquid metal to flow slowly, preventing excessive impact force from causing the liquid metal to splash due to complete blocking. The second anti-splash substrate 12 of the auxiliary anti-splash buffer structure 5 further blocks the sloshing liquid metal, enhancing the anti-splash effect. The second flow hole 13 on the anti-splash substrate 12 can also play a role in buffering and diverting, allowing some of the molten metal to flow smoothly. When the ladle 3 reaches the top of the injection chamber and begins to pour the molten metal, the first anti-splash substrate 6 and the second anti-splash substrate 12 continue to block the splashing of molten metal caused by the pouring action without affecting the normal flow of molten metal. The first flow hole 9 and the second flow hole 13 help the molten metal flow into the injection chamber more smoothly and reduce residue. After the feeding is completed, the drive robot arm 2 drives the ladle 3 to reset and wait for the next feeding instruction.

[0021] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
