Description

Technical Field

[0001] This disclosure relates to the field of waste removal technology, specifically to a waste removal device and a die-casting system. Background Technology

[0002] Die casting systems (commonly known as die casting islands) are highly integrated automated production units in modern manufacturing, primarily used for the die casting production of metal parts. As the complexity of castings increases, so does the amount of waste on them; this waste includes slag pockets, slag cakes, etc.

[0003] Among related technologies, current waste removal equipment has relatively low efficiency. Utility Model Content

[0004] The purpose of this disclosure is to provide a waste removal device and a die-casting system, which improves the efficiency of waste removal.

[0005] To achieve the above objectives, a first aspect of this disclosure provides a waste removal device, comprising: a base on which a removal chamber is disposed; a clamp disposed in the removal chamber and used to clamp a casting containing waste; and a removal apparatus, comprising a first removal mechanism and a second removal mechanism, wherein the first removal mechanism and the second removal mechanism are disposed in the same removal chamber, and the first removal mechanism and the second removal mechanism remove different types of waste.

[0006] Through the above technical solution, when it is necessary to remove different types of waste from a casting separately, the casting can be placed in the removal chamber and clamped by a fixture to fix it. Specifically, by placing the first and second removal mechanisms in the same removal chamber, compared to placing them in separate chambers, this arrangement eliminates the need for casting transfer and repeated fixing. In other words, two or more types of waste can be removed within a single removal chamber, thereby improving waste removal efficiency. Furthermore, this arrangement reduces the number of removal chambers, thus reducing the equipment footprint and lowering production costs.

[0007] In some possible implementations, the first removal mechanism is positioned behind the fixture and is used to remove the first waste material located behind the fixture. This allows the first removal mechanism to be positioned close to the first waste material, shortening its processing path and thereby improving the efficiency of waste removal.

[0008] In some possible implementations, the casting includes a first scrap, and the fixture includes a support mechanism positioned below and supporting the first scrap. This support mechanism supports the first scrap during removal, preventing it from falling off and causing the casting to shift, thus avoiding deviations in the cut position.

[0009] In some possible implementations, the support mechanism includes a base, a support plate, and a discharge structure. The support plate supports the first waste material, and the discharge structure drives the support plate to rotate relative to the base about a horizontally extending axis. Thus, when the first waste material is completely separated from the casting, the discharge structure can cause the first waste material on the support plate to flip and fall off.

[0010] In some possible implementations, the rotating shaft extends in a left-right direction and is arranged on the rear side of the base. Thus, when the unloading structure drives the support plate to rotate, the support plate can flip from front to back, causing the first waste material on the support plate to flip backward and fall off.

[0011] In some possible implementations, a baffle is provided on the front side of the support plate to restrict the forward movement of the first scrap after it has been removed. In this way, the baffle can isolate the first scrap from the casting, preventing the first scrap from sliding forward under the influence of gravity and interference from the casting, i.e., sliding close to the casting, which would cause the first scrap to come into contact with the casting.

[0012] In some possible implementations, the unloading structure includes an unloading cylinder connected between the base and the support plate, which drives the support plate to rotate. This rotation of the support plate by the unloading cylinder facilitates automated recycling of the first waste material, improving recycling efficiency.

[0013] In some possible implementations, the removal chamber includes a pick-up port and a discharge port, with the pick-up port located on the front side of the fixture and the discharge port located on the left or right side of the fixture. This arrangement of the pick-up and discharge ports avoids interference with the first removal mechanism, preventing loading or unloading operations from interfering with the first removal mechanism or unloading structure, thus improving safety during casting processing.

[0014] In some possible implementations, the clamp includes an upper clamping member and a lower clamping member, at least one of which is movably disposed in the material removal chamber in a vertical direction; the second removal mechanism includes a first cutting member and a second cutting member, the first cutting member being connected to the upper clamping member and the second cutting member being connected to the lower clamping member, the first cutting member and the second cutting member being used to jointly remove the second scrap from the casting. Thus, when the upper and lower clamping members approach each other and clamp the casting, synchronous cutting of the second scrap can be achieved.

[0015] According to a second aspect of this disclosure, a die-casting system is provided, including the waste removal device described above.

[0016] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Other features and advantages of this disclosure will be described in detail in the subsequent detailed description section. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0020] In this disclosure, unless otherwise stated, the directional terms "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. The directional terms "upper" and "lower" generally refer to "upper" and "lower" relative to each other in the direction of gravity when the corresponding component is in use. "Front" and "rear" are optional. Figure 1 The arrows indicate the "forward and backward" directions. "Left" and "Right" are secondary. Figure 1 The left and right arrows indicate the directions. "Up" and "Down" are optional. Figure 1 The arrows indicating the "up and down" directions are used. Furthermore, the use of terms such as "first" and "second" is intended to distinguish different components and does not imply sequence or importance. Additionally, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Those skilled in the art should understand that the above definitions are for explanation and illustration only and should not be construed as limiting the scope of this disclosure.

[0021] According to the first aspect of this disclosure, reference to Figures 1 to 5 As shown, a waste removal device is provided, including: a base 1, on which a removal chamber 11 is provided; a clamp 2, disposed in the removal chamber 11 and used to clamp a casting 10 containing waste; and a removal device 3, including a first removal mechanism 31 and a second removal mechanism 32, wherein the first removal mechanism 31 and the second removal mechanism 32 are disposed in the same removal chamber 11, and the first removal mechanism 31 and the second removal mechanism 32 remove different types of waste.

[0022] Through the above technical solution, when different types of waste need to be removed from the casting 10 separately, the casting 10 can be placed in the removal chamber 11 and clamped by the clamp 2 to fix the casting 10. Specifically, by placing the first removal mechanism 31 and the second removal mechanism 32 in the same removal chamber 11, compared to placing them in different removal chambers 11, this arrangement eliminates the need for the casting 10 to be moved around and repeatedly fixed. In other words, two or more types of waste can be removed within one removal chamber 11, thereby improving waste removal efficiency. Furthermore, this arrangement reduces the number of removal chambers 11, thus reducing the equipment footprint and lowering production costs.

[0023] For example, when a first scrap 101 and a second scrap 102 are formed on the casting 10, where the first scrap 101 is a slag stalk and the second scrap 102 is a slag bag, the first removal mechanism 31 and the second removal mechanism 32 can remove the slag bag and the slag stalk respectively by placing the casting 10 in the removal chamber 11. Both the slag bag and the slag stalk are waste structures attached to the casting 10 after casting. The slag bag is a structure in the casting system specifically used to collect impurities, slag, and gases in the molten metal, and is mostly located in non-functional areas of the casting 10, such as the edge or top of the casting 10. The slag stalk is the residual part left after the casting 10 is formed, which is the channel that guides the molten metal into the mold cavity in the casting system. Essentially, it is a channel-like waste that facilitates the casting process, and is mostly located on the side, bottom, or edge of the casting 10, usually extending along a certain direction of the casting 10, such as extending horizontally from the side of the casting 10.

[0024] It should be noted that the waste removal equipment disclosed herein may also include two or more removal chambers 11, so that each removal chamber 11 can remove two or more types of waste.

[0025] In some embodiments of this disclosure, reference is made to Figures 1 to 4 As shown, the first removal mechanism 31 is located behind the fixture 2 and is used to remove the first waste material 101 located behind the fixture 2. Thus, both the first removal mechanism 31 and the first waste material 101 are located behind the fixture, allowing the first removal mechanism 31 to be positioned close to the first waste material 101. This shortens the processing path of the first removal mechanism 31, thereby improving the waste removal efficiency and reducing errors during the removal of the first waste material 101. This also helps improve the removal accuracy of the first waste material 101 and ensures product quality.

[0026] In some embodiments of this disclosure, reference is made to Figures 3 to 5 As shown, the casting 10 includes a first scrap 101, and the fixture 2 includes a support mechanism 4. The support mechanism 4 is disposed on the lower side of the first scrap 101 and supports the first scrap 101. In this way, the support mechanism 4 can support the first scrap 101 during the removal process, preventing part of the first scrap 101 from falling off during the cutting process, causing the casting 10 to shift and resulting in a deviation in the cut position, or causing the partially removed first scrap 101 to pull the cut under the action of gravity, resulting in deformation at the cut and affecting the cutting accuracy. Therefore, it is beneficial to improve the cutting accuracy of the first removal mechanism 31 in the process of removing the first scrap 101 and improve product quality.

[0027] In some embodiments of this disclosure, reference is made to Figure 3 and Figure 4As shown, the support mechanism 4 includes a base 41, a support plate 42, and a discharge structure 43. The support plate 42 supports the first waste 101, and the discharge structure 43 drives the support plate 42 to rotate relative to the base 41 around a horizontally extending shaft 44. Thus, when the first removal mechanism 31 completely removes the first waste 101, separating it completely from the casting 10, the discharge structure 43 drives the support plate 42 to rotate, causing the first waste 101 on the support plate 42 to rotate and fall under gravity, thereby collecting the first waste 101. This improves the waste recycling efficiency and production efficiency.

[0028] In some embodiments of this disclosure, reference is made to Figure 3 and Figure 4 As shown, the rotating shaft 44 extends in the left-right direction and is arranged on the rear side of the base 41. The front side of the base 41 can be the side closer to the clamp 2, and the rear side of the base 41 can be the side farther from the clamp 2. The rotating shaft 44 is arranged on the rear side so that the support plate 42 can rotate around the rotating shaft 44 from front to back. In this way, the unloading structure 43 drives the support plate 42 to rotate from front to back, causing the first waste material 101 on the support plate 42 to rotate backward and fall off. This avoids the situation where the first waste material 101 gets stuck between the support plate 42 and the casting 10 when it falls from the front, making it difficult to recycle, or the first waste material 101 comes into contact with the casting 10, causing impact to the casting 10 and affecting product quality.

[0029] In some embodiments of this disclosure, reference is made to Figure 3 As shown, a baffle 45 is provided on the front side of the support plate 42. The baffle 45 is used to restrict the forward movement of the first waste 101 after it has been cut off. In this way, the baffle 45 can isolate the first waste 101 from the casting 10, and prevent the first waste 101 from sliding forward due to gravity and interference from the casting 10 during the removal process by the first removal mechanism 31. That is, it can slide close to the casting 10, causing the first waste 101 to come into contact with the casting 10 and cause wear on the casting 10, or the cuts to interfere with each other, causing the first waste 101 to get caught between the first waste 101 and the casting 10, making it difficult for the first waste 101 to fall off and making it inconvenient to recycle the first waste 101.

[0030] In some embodiments of this disclosure, reference is made to Figure 3 and Figure 4As shown, the unloading structure 43 includes an unloading cylinder connected between the base 41 and the support plate 42, and is used to drive the support plate 42 to rotate. This rotation of the support plate 42 by the unloading cylinder facilitates automated recycling of the first waste material 101, improving recycling efficiency. Furthermore, because the cylinder stroke is fixed, the stability of the output force during the rotation of the support plate 42 is ensured, preventing the waste material from flying out or falling off due to excessively fast or slow rotation speeds, thus affecting recycling efficiency.

[0031] The unloading cylinder can be an actuating cylinder that can rotate relative to the support plate 42 during the process of pushing the support plate 42 to flip backward, so as to adapt to the flipping path of the support plate 42. This disclosure does not impose any specific restrictions on this.

[0032] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the removal chamber 11 includes a material inlet 12 and a material outlet 13. The material inlet 12 is located on the front side of the fixture 2, and the material outlet 13 is located on the left or right side of the fixture 2. In this way, the casting 10 can be picked up and loaded through the material inlet 12 and the material outlet 13 respectively, thereby improving the transfer efficiency of the casting 10, increasing the production cycle, and avoiding the need for sequential loading and unloading when only a single opening is provided, which would affect the processing efficiency. Furthermore, since the first removal mechanism 31 is located on the rear side of the fixture 2, the arrangement of the material inlet 12 and the material outlet 13 can avoid interference with the first removal mechanism 31 or the unloading structure 43 during the loading or unloading operation, thus improving the safety of the casting 10 during the processing. In addition, by positioning the clamp 2 close to the material inlet 12, after the first removal mechanism 31 and the second removal mechanism 32 remove the first waste 101 and the second waste 102, the casting 10 can be quickly taken out from the material inlet 12 and put into the next process, which helps to shorten the transfer path of the casting 10 and improve production efficiency.

[0033] The material inlet 12 and the material outlet 13 can be respectively equipped with a placement robot and a retrieval robot to realize material picking and discharging operations. Furthermore, both the material inlet 12 and the material outlet 13 can be equipped with roller shutters. When the removal chamber 11 is idle, the roller shutters can be closed to shut off the material inlet 12 and the material outlet 13 to prevent dust and other substances from entering and damaging the equipment.

[0034] In some embodiments of this disclosure, reference is made to Figures 1 to 4As shown, the clamp 2 includes an upper clamping member 21 and a lower clamping member 22, at least one of which is movably disposed in the material removal chamber in the vertical direction; the second removal mechanism 32 includes a first cutting member 321 and a second cutting member 322, the first cutting member 321 is connected to the upper clamping member 21, and the second cutting member 322 is connected to the lower clamping member 22, the first cutting member 321 and the second cutting member 322 are used to jointly remove the second waste 102 of the casting 10. Thus, when it is necessary to remove the second waste 102 from the casting 10, the casting 10 is placed between the upper clamping member 21 and the lower clamping member 22, and supported by the lower clamping member 22. By driving one of the upper clamping member 21 and the lower clamping member 22 to move closer to the other, the casting 10 is clamped. Since the upper clamping member 21 and the lower clamping member 22 are respectively provided with the first cutting member 321 and the second cutting member 322, when the upper clamping member 21 and the lower clamping member 22 approach each other and clamp the casting 10, the second waste 102 can be cut synchronously. This helps to ensure the cutting accuracy of the second waste 102 on the casting 10 by the first cutting member 321 and the second cutting member 322. Meanwhile, the clamping of the casting 10 by the upper clamping member 21 and the lower clamping member 22 can ensure the stability of the casting 10, which facilitates the removal of the first waste 101 by the first removal mechanism 31. In this way, only the upper clamping member 21 and the clamping member need to be set to press the casting, which can simultaneously meet the stability of the casting 10 during the removal of the first waste 101 and the second waste 102. There is no need to set the pressing structure or clamp 2 of the first removal mechanism 31 and the second removal mechanism 32 respectively, which helps to simplify the structure of the casting 10 processing equipment and reduce production costs.

[0035] Among them, reference Figures 3 to 5 As shown, the first cutting member 321 can be driven by a hydraulic system to move the upper clamping member 21 downward to approach the casting 10 and cut the second waste 102 on the casting 10. The second cutting member 322 can be driven by a hydraulic cylinder to move the second cutting member 322 upward relative to the lower clamping member 22 to cut the second waste 102.

[0036] Additionally, refer to Figures 3 to 5 As shown, the upper clamping member 21 can be an upper mold tooling, and the lower clamping member 22 can be a lower mold tooling. Thus, the upper clamping member 21 and the lower clamping member 22 can be configured as contour-following tooling that matches the shape of the casting 10, so that when the casting 10 is placed on the lower clamping member 22, the casting 10 can fit snugly against the lower clamping member 22, ensuring the stability of the support for the casting 10. Furthermore, refer to... Figure 5As shown, multiple positioning pins can be provided on the lower clamping member 22, and positioning holes that match the positions of the positioning pins can be provided on the lower side of the casting 10. The positioning pins are inserted into the positioning holes to achieve positioning. In this way, the positioning pins and the contouring fixture can jointly position the lower clamping member 22, prevent the fixture 2 from moving, ensure positioning accuracy, thereby improving cutting accuracy and reducing the amount of broken residue.

[0037] According to a second aspect of this disclosure, a die-casting system is provided, including the waste removal device described above. This die-casting system possesses all the beneficial effects of the aforementioned waste removal device, which will not be elaborated upon herein.

[0038] Among them, reference Figure 1 and Figure 2 As shown, the first removal mechanism 31 can be a plasma cutter or a laser cutter. A robotic arm controls the cutter to cut the first waste material 101. The top platform of the removal chamber 11 can be equipped with a hydraulic system and a dust removal system. The hydraulic system can control the upper clamping member 21 to move closer to the lower clamping member 22 to clamp the casting 10, or move away from the lower clamping member 22 to release the casting 10. The dust removal system is used to remove dust generated during the cutting process of the first removal mechanism 31. A safety door can be installed on the side opposite to the discharge port 13 to allow opening the removal chamber 11 for maintenance of the internal devices. A maintenance platform leading to the safety door can also be installed on the side of the removal chamber 11 away from the discharge port 12, allowing personnel to open the door for maintenance operations. On the same side of the maintenance platform, an electrical cabinet placement platform can also be installed to house the electrical cabinet for control operations. The lower sides of the first removal mechanism 31 and the second removal mechanism 32 may be provided with discharge systems, such as collection bins for collecting the first waste 101 and the second waste 102, so as to collect the first waste 101 and the second waste 102 separately.

[0039] Below, for reference Figures 1 to 5As shown, this disclosure will provide a detailed description of the specific usage process of the waste removal equipment in conjunction with the above-described specific embodiments. When the first waste 101 of the casting 10 is a stalk and the second waste 102 is a slag bag, and it is necessary to remove the slag bag and the stalk, the casting 10 is moved from the discharge port 13 into the removal chamber 11 and placed between the upper clamping member 21 and the lower clamping member 22, supported by the lower clamping member 22, with the first waste 101 placed close to the first removal mechanism 31. The upper clamping member 21 is driven downward by the hydraulic system, so that the first cutting member 321 simultaneously approaches the casting 10 to break and cut the slag bag on the edge of the casting 10. The second cutting member 322 is driven upward by the cylinder to cooperate with the first cutting machine to break and cut the slag bag. As the upper clamping member 21 moves downward, it drives the second removal mechanism 32 to remove the slag bag, thus clamping the casting 10. Therefore, the first removal mechanism 31 can cut the material handle on the casting 10 clamped by the upper clamping member 21 and the lower clamping member 22, and the support plate 42 can support the cut material handle. When the material handle is completely separated from the casting 10, the unloading cylinder is lifted upward, so as to drive the support plate 42 to flip from front to back, thereby causing the material handle on the support plate 42 to fall downward into the collection bucket to realize the recovery of the material handle.

[0040] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0042] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
