Abstract
Description
Technical Field
[0001] This application relates to the field of die casting technology, and in particular to a die casting device for compressing and preventing shrinkage holes in a cap-opening machine connecting support casting. Background Technology
[0002] The cover-opening machine connecting support is a structural support component installed on the cover-opening machine to connect the main body of the cover-opening machine with the furnace cover, robotic arm, hydraulic cylinder, and other parts, and to bear loads and transmit motion and force. During the manufacturing process, the cover-opening machine connecting support is usually die-cast using a die-casting device.
[0003] In existing technologies, molten metal is typically injected into a mold cavity, and after it cools and solidifies, the mold is opened to obtain the casting of the cover-opening machine connecting support. To improve die-casting efficiency, the mold is often equipped with multiple cavities, allowing multiple castings to be formed simultaneously with a single injection. After the casting is formed, it is ejected from the cavity by a demolding mechanism, and a collection box is placed below the mold to catch the falling castings.
[0004] However, in some cases, to achieve continuous flow between processes, a conveyor belt is installed under the mold instead of a collection box. The demolded casting falls directly onto the conveyor belt, which then transports it to the next process. However, because the casting's posture is uncontrolled during demolding, it often piles up haphazardly on the conveyor belt. This makes it difficult for subsequent processes to automatically pick up and position the casting, thus affecting the processing efficiency of subsequent processes. Summary of the Invention

[0023] The beneficial effects of this invention are as follows:
[0024] 1. The present invention relates to a die-casting device for pressure compensation and anti-shrinkage hole prevention of a cap-opening machine connecting support casting. Utilizing a material transfer auxiliary component, when the castings after demolding need to be transferred to the next process via a conveyor belt, it can achieve automatic orientation and equidistant arrangement of the castings after demolding. This effectively solves the problem in the prior art where castings are randomly piled on the conveyor belt after demolding, making it difficult to directly perform automated material handling and positioning. Simultaneously, the spacing of the castings arranged in the material discharge channel can be adjusted, and the adjusted castings fall onto the conveyor belt, thereby ensuring that subsequent processes can synchronously handle material handling and positioning at fixed intervals, improving the efficiency and stability of automated processing. The overall device has a compact structure and continuous operation, enabling automated continuous processing of castings from demolding, collection, orientation, arrangement to placement on the conveyor belt, which is beneficial for improving production efficiency.
[0025] 2. The pressure-compensating and anti-shrinkage hole die casting device for the connecting support casting of the cover-opening machine described in this invention utilizes a pressure-compensating device to locally pressurize and compress the molten metal in the mold cavity, so that the casting receives sufficient molten metal replenishment during the cooling and solidification process, avoiding the formation of shrinkage cavities or porosity in the thick area at the connection between the tube body and the disc body due to the cooling and shrinkage of the molten metal, thereby improving the internal density and molding quality of the casting.
[0026] 3. The pressure-compensating and anti-shrinkage hole die-casting device for the connecting support casting of the cover-opening machine described in this invention utilizes a row number control component to control the final number of rows of castings arranged on the conveyor belt. With this setup, the number of castings arranged and the conveyor width can be flexibly adjusted according to the actual needs of subsequent processes, further facilitating subsequent synchronous gripping, equidistant positioning, and batch processing.
[0027] 4. The cover-opening machine connecting support casting pressure-compensating and anti-shrinkage hole die-casting device of the present invention utilizes an integrated component for promoting slippage and preventing separation. During the vibration of the transfer frame, multiple rotating rollers and friction rollers rotate simultaneously.
[0028] When the rotating roller rotates, multiple actuating pads on its surface will contact the tube parts of multiple castings in the feeding channel and provide a downward actuating force, thereby causing the castings that have entered the feeding channel to maintain the downward trend and prevent them from falling out of the feeding channel again due to continuous vibration. This allows the castings to maintain a stable orientation and continue to be arranged along the feeding channel.
[0029] When the friction roller rotates, it provides a frictional force along the support surface to the castings that are resting on the support surface. This causes the castings that were originally placed horizontally or resting on the support surface formed by the horizontal plate and the width adjustment plate to be continuously disturbed, thereby changing their resting state and prompting them to slide into the feeding channel. This effectively reduces the phenomenon of castings being stuck or blocked on the support surface, and improves the efficiency of casting processing and the continuity of feeding.
[0030] 5. The die-casting device for pressurizing and preventing shrinkage holes in the casting of the cover-opening machine connecting support as described in this invention utilizes a downward pressing structure. After the bottom of the casting is attached to the surface of the conveyor belt, before the width-adjusting plate retracts into the horizontal plate, multiple pressure rods descend simultaneously to press down the tops of multiple castings in multiple feeding channels. At this time, the width-adjusting plate is driven back into the horizontal plate. Due to the vertical pressing action of the pressure rods, the position of the casting is restricted and it is no longer moved by the friction force when the width-adjusting plate retracts. Then, the pressure rods move away from the casting, placing the casting on the conveyor belt. This avoids jamming or displacement of the casting, allowing each casting to fall stably onto the conveyor belt in a predetermined position, ensuring the neatness of the casting arrangement and the stability of subsequent conveying.

Detailed Implementation
[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0047] Example 1:
[0048] like Figures 1-14 As shown, a die-casting device for pressure compensation and anti-shrinkage hole of a cap-opening machine connecting support casting includes a base 1. The base 1 is provided with a mounting plate 6 and a mounting plate 8. The mounting plate 6 is detachably provided with a mold 5, and the mounting plate 8 is detachably provided with a mold 9. The mold 5 and the mold 9 are respectively provided with a plurality of cavities 31 and 22. The plurality of cavities 31 correspond to the plurality of cavities 22. When the mold 5 and the mold 9 are combined, a plurality of complete forming cavities are formed. The base 1 is provided with a material feeding transfer auxiliary component.
[0049] The material transfer auxiliary component includes a transfer frame 2 located below mold 1 5 and mold 2 9. Multiple horizontal plates 26 are arranged and fixedly connected at equal intervals along the bottom of the inner side of the transfer frame 2. A width adjustment plate 48 is slidably inserted into the horizontal plate 26. The multiple horizontal plates 26 and the width adjustment plate 48 cooperate with each other to form a material transfer channel that matches the specifications of the casting.
[0050] The base 1 is equipped with a transmission mechanism for flipping the transfer frame 2 and generating vibration;
[0051] The transfer frame 2 is equipped with a spacing adjustment structure for adjusting the distance between adjacent castings in the material feeding channel.
[0052] In this embodiment, as Figures 2-4 , Figure 8 , Figures 11-14 As shown, multiple guide rods 11 are fixedly connected to the mounting plate 6 along the horizontal direction. The ends of the multiple guide rods 11 are fixedly connected to a fixing frame 12. The mounting plate 8 is slidably mounted on the multiple guide rods 11 along the horizontal direction. A cylinder 7 is fixedly mounted on the mounting plate 6. The piston end of the cylinder 7 is fixedly connected to one end of the mounting plate 8.
[0053] Mounting plate 6 is equipped with a demolding assembly;
[0054] The demolding assembly includes multiple demolding rods 15 that slide laterally through the mounting plate 6, and each demolding rod 15 slides through a cavity 31. One end of the multiple demolding rods 15 is fixedly connected to a connecting plate 16. A cylinder 10 is fixedly mounted on the mounting plate 6, and the piston end of the cylinder 10 is fixedly connected to one side of the connecting plate 16.
[0055] The transmission mechanism includes two lifting plates 4 symmetrically distributed on both sides of the transfer frame 2. A flip plate 35 is rotatably mounted on the lifting plate 4. Multiple spring dampers 36 are fixedly mounted on the flip plate 35. The piston ends of the multiple spring dampers 36 are fixedly connected to the transfer frame 2. A motor 21 for driving the flip plate 35 to rotate is mounted on the lifting plate 4. An electromagnetic vibrator 37 is mounted on the transfer frame 2. Two columns 3 are symmetrically mounted on the base 1. A lead screw linear module 49 is mounted on the column 3. The two lifting plates 4 are respectively fixed to the moving ends of the lead screw linear module 49 on both sides.
[0056] An adjustment frame 47 is provided on the upper edge of the transfer frame 2, and multiple width adjustment plates 48 are fixedly connected to the adjustment frame 47. A cylinder 46 is fixedly provided on the transfer frame 2, and the piston end of the cylinder 46 is fixedly connected to one end of the adjustment frame 47.
[0057] The adjustable pitch structure includes a second lead screw linear module 38 mounted on the transfer frame 2. A transverse frame 25 is fixedly mounted on the moving end of the second lead screw linear module 38. A first lead screw linear module 27 is mounted vertically on the transverse frame 25. A variable pitch slide 28 is fixedly mounted on the moving end of the first lead screw linear module 27. A plurality of sliders 29 that can move simultaneously are mounted on the variable pitch slide 28. An adjusting rod 30 is fixedly connected to each slider 29. An elastic pad is provided at the bottom of the adjusting rod 30.
[0058] Specifically, in this embodiment, the cap-opening machine connecting support casting adopts an integral molding structure, mainly composed of a tubular body and a disc-shaped base. The tubular body is cylindrical, with a central hole along its axial direction inside; the disc-shaped base is located at one end of the tubular body, and its outer diameter is larger than that of the tubular body. For ease of subsequent explanation, the tubular body will be referred to simply as the "tube body," and the disc-shaped base will be referred to simply as the "disc body."
[0059] First, the conveyor belt used for transporting castings is placed below the transfer frame 2, and the conveying direction of the conveyor belt is consistent with the length direction of the unloading channel.
[0060] By using cylinder 7 to drive mounting plate 8 to slide along multiple guide rods 11, the distance between mold 5 and mold 9 can be adjusted, thus achieving separation or mold closing between the two.
[0061] When mold 5 and mold 9 are in the closed state, multiple cavities 22 and corresponding cavities 31 cooperate with each other to form multiple complete molding cavities. At this time, molten metal can be injected into each molding cavity through the injection port on mold 5 and the corresponding pipeline.
[0062] After the molten metal cools and solidifies, multiple castings of the lifting machine connecting support can be formed simultaneously in multiple forming cavities. Then, cylinder 7 drives mounting plate 8 to move in the opposite direction, separating mold 5 from mold 9. Then, cylinder 10 drives connecting plate 16 to move laterally, causing multiple demolding rods 15 to pass through multiple cavities 31 simultaneously, and ejecting the castings embedded in the cavities 31, thus completing one die casting process.
[0063] The ejected casting falls into the transfer frame 2. Then, the electromagnetic vibrator 37 is activated, and the transfer frame 2 vibrates under the coordinated action of the electromagnetic vibrator 37 and the spring damper 36. When the transfer frame 2 vibrates, the multiple castings inside it move continuously. Furthermore, because multiple horizontal plates 26 and the width adjustment plate 48 cooperate to form multiple feeding channels, and the width of these feeding channels is greater than the outer diameter of the tube body but smaller than the diameter of the disc body, the tube body of the casting can pass through the feeding channels, while the disc body will be stuck above the feeding channels.
[0064] In this way, as the transfer frame 2 vibrates continuously, multiple castings will continuously adjust their posture until their tube parts pass through the feeding channel. All castings passing through the feeding channel will face the same direction and be arranged linearly within the channel. After all castings in the transfer frame 2 have passed through the feeding channel, motor 21 will rotate the transfer frame 2 by a certain angle, causing it to tilt. The multiple castings in the feeding channel will then slide along the channel under gravity until their disc-shaped parts fit together. At this point, the axial distance between two adjacent castings in each feeding channel will be the same. Then, the transfer frame 2 will be driven back to horizontal.
[0065] Next, the linear module 28 is used to drive the transverse frame 25 to move laterally on the transfer frame 2, so that the variable pitch slide 28 is aligned with multiple feeding channels in sequence. Furthermore, according to the spacing between adjacent castings, the variable pitch slide 28 can drive multiple sliders 29 to move simultaneously, so that the axial distance between adjacent adjusting rods 30 changes and makes the distance equal to the axial distance between adjacent castings.
[0066] Since the adjusting rod 30 furthest from the transverse frame 25 is aligned with the end of the unloading channel, and the corresponding slider 29 does not move, and because a casting remains at the end of the unloading channel due to the tilting of the transfer frame 2, when multiple adjusting rods 30 are located above a single unloading channel, multiple adjusting rods 30 will simultaneously align with the tops of multiple castings. The variable pitch slide table 28 uses one slider 29 as a reference to move the other multiple sliders 29 simultaneously to achieve variable pitch operation, which is existing technology and will not be elaborated further here.
[0067] At this point, the linear screw module 27 can be used to drive the variable pitch slide 28 to descend, causing the elastic pad at the bottom of the adjusting rod 30 to press the casting. Subsequently, as needed, multiple sliders 29 can be driven to move simultaneously, thereby changing the spacing between adjacent castings in the feeding channel. Repeat the above operation until the spacing adjustment operation has been completed for all castings in the feeding channel.
[0068] Next, the transfer frame 2 is lowered by the linear screw module 49, so that the bottom of the casting tube is in contact with the surface of the conveyor belt. The cylinder 46 drives the adjusting frame 47 to move laterally on the transfer frame 2, so that multiple width adjustment plates 48 slide on multiple horizontal plates 26 at the same time, so that the width of the unloading channel increases until the casting disc can pass through. Then, multiple castings will be stably placed on the conveyor belt with the tube facing down, and then the transfer frame 2 is driven to rise.
[0069] At this point, multiple castings are stably placed on the conveyor belt in a uniform, tube-down position, and are neatly transported to the next process by the conveyor belt. This achieves automatic orientation and equidistant arrangement of the castings after demolding, avoiding the problem of messy accumulation of castings on the conveyor belt. Compared with existing technologies, this solution sets up a feeding channel formed by the cooperation of a horizontal plate 26 and a width-adjusting plate 48. Utilizing the structural characteristic that the width of the feeding channel is greater than the outer diameter of the tube body but smaller than the diameter of the disc body, the castings can only pass through the feeding channel in a uniform posture with the tube body facing down and the disc body facing up during vibration. This effectively solves the problem in existing technologies where castings accumulate haphazardly on the conveyor belt after demolding, making it difficult to directly automate material handling and positioning. Simultaneously, the spacing of castings arranged in the feeding channel can be adjusted, allowing the adjusted castings to fall onto the conveyor belt. This ensures that subsequent processes can synchronously handle material handling and positioning at fixed intervals, improving the efficiency and stability of automated processing. The overall device has a compact structure and smooth operation, enabling automated continuous processing of castings from demolding, collection, orientation, arrangement to placement on the conveyor belt, thus improving production efficiency.
[0070] Furthermore, since both mold 5 and mold 9 are detachable, mold 5 and mold 9 of the appropriate specifications can be replaced according to production needs. After replacement, the width of the material feeding channel can be adjusted according to the new cavity specifications to match the casting size. Moreover, both mold 5 and mold 9 are equipped with holes that mate with the demolding components, thereby improving the versatility of the entire device.
[0071] Example 2:
[0072] In this embodiment, as Figure 5 and Figure 7 As shown, the mounting plate 28 is equipped with a pressure replenishing device 17, which includes a pressure replenishing cylinder and a liquid storage chamber. The liquid storage chamber is equipped with a liquid filling port. The cavity 1 22 is equipped with a pressure hole 23. The liquid outlet of the pressure replenishing device 17 is connected to multiple pressure holes 23 through pipelines.
[0073] Specifically, during the die casting process, after the molten metal is filled into the forming cavity formed by the combination of multiple cavity 1 22 and cavity 2 31 through the injection port, before the molten metal has completely solidified, the pressure replenishing cylinder of the pressure replenishing device 17 pushes the molten metal in the storage chamber, so that the molten metal enters multiple pressure holes 23 through the pipeline from the outlet end, and is replenished from the pressure holes 23 into the thick parts of cavity 1 22 that are prone to shrinkage cavities. This locally pressurizes and replenishes the molten metal in the cavity, so that the casting receives sufficient molten metal replenishment during the cooling and solidification process. This avoids the formation of shrinkage cavities or porosity in thick areas such as the connection between the tube body and the plate body due to the cooling and shrinkage of the molten metal, which is conducive to improving the internal density and forming quality of the casting.
[0074] In addition, the replaced mold 29 is also compatible with the pressure compensation device 17.
[0075] Example 3:
[0076] In this embodiment, as Figure 8 and Figure 12 As shown, the transfer frame 2 is equipped with a row number control component;
[0077] The row number control component includes two guide rods 40 that slide laterally through the side wall of the transfer frame 2. One end of the two guide rods 40 located inside the transfer frame 2 is fixedly connected to the feed plate 24. A cylinder 39 is fixedly installed on the transfer frame 2. The piston end of the cylinder 39 is fixedly connected to one side of the feed plate 24.
[0078] Specifically, the transfer frame 2 is divided into a covered area and an uncovered area by the feeding plate 24. After the casting is ejected, it first slides through the feeding plate 24 to the uncovered area within the transfer frame 2. By using cylinder 39 to move the feeding plate 24 laterally, the area of the uncovered area can be adjusted, thus controlling the number of exposed feeding channels and consequently the number of rows of castings arranged on the conveyor belt. This setup allows for flexible adjustment of the number of castings and the conveyor width according to the actual needs of subsequent processes, further facilitating subsequent synchronous gripping, equidistant positioning, and batch processing.
[0079] Example 4:
[0080] In this embodiment, as Figure 8 , Figure 9 , Figure 11 , Figure 13 As shown, the transfer frame 2 is equipped with an integrated component for promoting slippage and preventing detachment;
[0081] The integrated component for promoting slippage and preventing detachment includes multiple rotating rollers 33 and friction rollers 32. Each rotating roller 33 is rotatably mounted at the bottom of a horizontal plate 26, and each friction roller 32 is rotatably mounted at the top groove of a horizontal plate 26. A pulley 44 is fixedly sleeved at one end of each rotating roller 33 and friction roller 32. The pulley 44 is meshed with a belt 45. A worm gear 43 is fixedly sleeved at the end of each rotating roller 33. A worm 42 is rotatably mounted on the intermediate frame 2. Multiple worm teeth are intermittently provided on the worm 42, and each worm tooth meshes with a worm gear 43. A motor 41 for driving the worm 42 to rotate is provided on the intermediate frame 2. Multiple elastic material actuating pads 34 are fixedly mounted on the rotating roller 33 along the circumference.
[0082] Specifically, in the above embodiments, although vibration can induce the castings to fall into the feeding channels, castings already in the channels are prone to detaching again due to continuous vibration. This causes the oriented castings to scatter again or change their orientation, affecting the stability of the casting arrangement and the accuracy of subsequent spacing adjustments. Furthermore, while multiple horizontal plates 26 and width-adjusting plates 48 cooperate to form multiple feeding channels, they also create multiple support surfaces. During vibration, some castings may remain on these support surfaces, unable to smoothly enter the feeding channels, causing them to become stuck or blocked during feeding, affecting the efficiency of casting arrangement and the continuity of conveying.
[0083] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:
[0084] During the vibration of the transfer frame 2, the worm gear 42 is driven to rotate by the motor 41, and multiple rotating rollers 33 and friction rollers 32 can rotate simultaneously under the transmission cooperation of the worm gear 42, worm wheel 43, pulley 44 and belt 45.
[0085] When the rotating roller 33 rotates, the multiple actuating pads 34 on its surface will contact the tube parts of multiple castings in the feeding channel and provide a downward actuating force, thereby causing the castings that have entered the feeding channel to maintain the downward trend and prevent them from falling out of the feeding channel again due to continuous vibration, so that the castings can maintain a stable orientation and continue to be arranged along the feeding channel.
[0086] When the friction roller 32 rotates, it provides a frictional force along the support surface to the castings that are resting on the support surface. This causes the castings that were originally placed horizontally or resting on the support surface formed by the horizontal plate 26 and the width adjustment plate 48 to be continuously disturbed, thereby changing their resting state and prompting them to slide into the feeding channel. This effectively reduces the phenomenon of castings being stuck or blocked on the support surface, and improves the efficiency of casting processing and the continuity of feeding.
[0087] Example 5:
[0088] like Figure 5 and Figure 6 As shown, mounting plate 28 is equipped with a pressing structure;
[0089] The pressing structure includes a support rod 20 fixedly connected to the mounting plate 28. A rack 13 is slidably mounted on the support rod 20 along the vertical direction. Multiple pressure rods 14 aligned with multiple feeding channels are fixedly connected to the bottom of the rack 13. A gear 18 is rotatably mounted on the support rod 20. The gear 18 meshes with the teeth on the rack 13. A motor 19 is mounted on the support rod 20 to drive the gear 18 to rotate.
[0090] Specifically, in the above embodiment, when the casting is placed on the conveyor belt, the width adjustment plate 48 needs to be retracted into the horizontal plate 26 before the casting can fall onto the conveyor belt. However, since the disc part of the casting is placed on the width adjustment plate 48, the disc part is easily moved along with the width adjustment plate 48 due to friction during the process of the width adjustment plate 48 retracting into the horizontal plate 26. This can cause the casting to get stuck on the width adjustment plate 48 or deviate from the predetermined position, thereby affecting the normal unloading and neatness of the casting.
[0091] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:
[0092] After the bottom of the casting is in contact with the surface of the conveyor belt, and before the width adjustment plate 48 retracts into the horizontal plate 26, the motor 19 drives the gear 18 to rotate, causing the rack 13 to descend, which in turn drives multiple pressure rods 14 to descend simultaneously, pressing down the tops of multiple castings in multiple feeding channels. At this time, the width adjustment plate 48 is driven to retract into the horizontal plate 26. Due to the vertical pressing action of the pressure rods 14, the position of the casting is restricted, and it is no longer moved by the friction force when the width adjustment plate 48 retracts. Then the pressure rods 14 move away from the casting, placing the casting on the conveyor belt, thereby avoiding jamming or displacement of the casting, and ensuring that each casting can fall stably on the conveyor belt in a predetermined position, ensuring the neatness of the casting arrangement and the stability of subsequent conveying.
