Description

Technical Field

[0001] This invention relates to the field of die casting machine technology, specifically to a die casting machine for processing die casting parts. Background Technology

[0002] In the manufacturing sector, die castings are widely used in numerous industries such as automotive, electronics, and aerospace due to their advantages of high precision, high strength, and good surface quality. Die castings are typically produced using die casting machines, which inject molten metal into a mold, where it is cooled and solidified to obtain the desired shape.

[0003] Traditional die-casting machines have many limitations in structure and function, making it difficult to meet the requirements of modern industrial production for high efficiency, high quality, and automation. Specifically, traditional die-casting machines mainly suffer from the following problems: 1. Inconvenient Mold Operation: Traditional die-casting machines rely heavily on manual labor or simple mechanical structures for mold opening and closing, as well as top plate opening and closing. This is not only cumbersome but also makes it difficult to guarantee accuracy and consistency. For example, during mold opening and closing, manual adjustment of the positions of various mold components is required, which is not only labor-intensive but also prone to mold damage or inconsistent die-casting quality due to improper operation. Furthermore, the opening and closing of the mold top plate lacks effective automated control, impacting production efficiency.

[0004] 2. Difficulty in mold cleaning: During the die casting process, solidified metal material easily remains on the inner wall of the mold. If these residues are not cleaned in time, they will affect the quality of the next die casting and may even damage the mold. However, traditional die casting machines lack effective mold cleaning devices and usually require manual cleaning with tools. This is not only inefficient but also makes it difficult to completely remove residues from the inner wall of the mold, especially for some complex mold parts, where cleaning is even more difficult.

[0005] 3. Low production efficiency: Due to the numerous problems mentioned above in the mold operation, heating and injection, cleaning, and unloading processes of traditional die-casting machines, the entire production process is discontinuous, requiring long waiting and adjustment times between each step, making continuous and efficient production impossible. The limitations of traditional equipment are particularly pronounced when producing multiple die-cast parts simultaneously or when producing die-cast parts of different specifications, making it difficult to meet the demands of large-scale industrial production.

[0023] Please refer to Figure 3 As shown, the heating mechanism 2 includes two sets of support plates 201, with a first lead screw 202 rotatably connected between the two sets of support plates 201. A movable part 205 is threadedly connected to the outer wall of the first lead screw 202, and the movable part 205 is slidably connected to a first guide rod 203. The two ends of the first guide rod 203 are respectively welded to the inner walls of the two sets of support plates 201.

[0024] Those skilled in the art will understand that the first lead screw 202 is rotated by the output end of the first stepper motor 204, causing the movable part 205 to move horizontally back and forth along the outer wall of the first guide rod 203, thereby driving the heating cylinder 206 and the liquid outlet pipe 207 to move horizontally back and forth as a whole; a high-temperature heating plate is embedded in the inner wall of the heating cylinder 206, which can heat the metal raw material at high temperature to form a molten metal liquid, and by controlling the opening of the liquid outlet valve 208, the molten metal liquid flows down. Example 3

[0025] Please refer to Figure 4 and Figure 6 As shown, the mold mechanism 3 includes a second lead screw 301 and a second guide rod 302. The second lead screw 301 is rotatably connected to the rear side inside the housing 1, and the second guide rod 302 is fixedly connected to the rear side inside the housing 1. A second stepper motor 303 that drives the second lead screw 301 to rotate is installed on the outer wall of the housing 1. Two sets of movable blocks 304 are threadedly connected to the outer wall of the second lead screw 301. Both sets of movable blocks 304 are slidably connected to the second guide rod 302, and a multi-stage electric telescopic rod 305 is installed inside the movable block 304. The output end of the multi-stage electric telescopic rod 305 is fixedly connected to the mold frame 306.

[0026] Please refer to Figure 7 As shown, the mold frame 306 is in a "C" shape. Both sides of the bottom of the mold frame 306 are rotatably connected to the mold side plates 308 through rotating shafts 307. The outer ends of the rotating shafts 307 are fixedly installed with first bevel gears 309. The top of one set of mold side plates 308 is rotatably connected to the mold top plate 310. The mold top plate 310 is connected to the other set of mold side plates 308 through a lock 311. And at the joints of the mold side plates 308, the mold top plate 310 and the mold frame 306 when the mold is closed, a seal groove and gasket structure is provided.

[0027] Those skilled in the art can understand that by controlling the output end of the second stepping motor 303 to rotate, the second screw rod 301 rotates, driving the two movable blocks 304 to perform horizontal left and right reciprocating movements along the outer wall of the second guide rod 302, thereby realizing driving the two mold frames 306 to perform horizontal left and right reciprocating movements. And by controlling the output ends of the two multi-stage electric telescopic rods 305 to extend or contract respectively, the two mold frames 306 are driven to move forward or backward respectively; At the beginning of the mold body in the present invention, the two mold side plates 308 are both in a vertical state and are respectively fitted to both sides of the mold frame 306, and the mold top plate 310 and the left mold side plate 308 are fixed through the lock 311, thus forming a hollow cuboid and maintaining this state. This state is called "closing the mold". In the present invention, the mold frame 306, the mold side plates 308 and the mold top plate 310 form the mold body; In addition, a water cooling pipe system is installed inside the mold frame 306, the mold side plates 308 and the mold top plate 310. When the mold is closed, the molten liquid inside is cooled and formed into a die-casting. Embodiment 4

[0028] Please refer to Figure 6 As shown, the first auxiliary mechanism 4 includes a rotating rod 401, second bevel gears 402 and a first driving motor 403. The rotating rod 401 is rotatably connected inside the box body 1. Two sets of second bevel gears 402 are provided and are both fixedly connected to the outer wall of the rotating rod 401. The first driving motor 403 is fixedly installed on the outer wall of the box body 1. The outer end of the rotating rod 401 is fixedly connected to the output end of the first driving motor 403.

[0029] Those skilled in the art can understand that under the combined action of the output end of the second stepping motor 303 and the output end of the multi-stage electric telescopic rod 305, the two first bevel gears 309 on one set of mold frames 306 can be respectively engaged with the two second bevel gears 402 on the rotating rod 401. The purpose of doing this is to prevent the mold body from unfolding when the mold top plate 310 is opened later to inject molten raw materials. Example 5

[0030] Please refer to Figure 8 As shown, the second auxiliary mechanism 5 includes a second drive motor 501 fixedly installed on the front side wall of the housing 1. The output end of the second drive motor 501 extends into the housing 1 and is fixedly connected to the first electric push rod 502 through a connector. The output end of the first electric push rod 502 is fixedly connected to the first mounting block 503. A second electric push rod 504 is provided on the right side wall of the first mounting block 503. The output end of the second electric push rod 504 is fixedly installed with the second mounting block 505.

[0031] Please refer to Figure 8 As shown, a third electric push rod 508 is rotatably connected inside the second mounting block 505. The output end of the third electric push rod 508 is fixedly connected to the key 510. A third drive motor 506 is provided on the top of the second mounting block 505. A drive gear 507 is fixedly connected to the output end of the third drive motor 506. A driven gear 509 is fixedly installed on the outer wall of the third electric push rod 508. The drive gear 507 and the driven gear 509 are meshed together.

[0032] Those skilled in the art will understand that when the two sets of first bevel gears 309 on one set of mold frames 306 mesh with the two sets of second bevel gears 402 on the rotating rod 401, the key 510 is positioned directly above the lock hole of the lock 311 by controlling the cooperation between the output end of the second electric push rod 504 and the output end of the first electric push rod 502. Then, by driving the output end of the third electric push rod 508 to extend, the key 510 moves downward and is inserted into the lock hole of the lock 311. Finally, by driving the output end of the third drive motor 506... The output end drives the drive gear 507 to rotate, causing the driven gear 509 and the third electric push rod 508 to rotate as a whole, thereby driving the key 510 to rotate and disconnecting the mold top plate 310 from the left mold side plate 308. In addition, the center of the second drive motor 501 and the center of rotation of the mold top plate 310 around the top of the right mold side plate 308 are on the same straight line. Therefore, by driving the output end of the second drive motor 501 to rotate, the mold top plate 310 is rotated 90 degrees upward to a vertical position. It is worth mentioning that after the mold top plate 310 is rotated to the vertical position, it can remain in that position even if the key 510 is pulled out, similar to the structure of a laptop computer in real life. Example 6

[0033] Please refer to Figure 9As shown, the cleaning mechanism 6 includes a third lead screw 601 rotatably connected to the front side of the inside of the housing 1. An L-shaped plate 604 is threaded onto the outer wall of the third lead screw 601. The vertical plate of the L-shaped plate 604 is slidably connected to a third guide rod 602. The third guide rod 602 is fixedly connected to the front side of the inside of the housing 1. A third stepper motor 603 that drives the third lead screw 601 to rotate is installed on the outer wall of the housing 1. A fourth electric push rod 605 is provided on the top of the horizontal plate of the L-shaped plate 604. The output end of the fourth electric push rod 605 is fixedly connected to a first scraper 606. The width of the first scraper 606 is adapted to the internal width of the mold frame 306.

[0034] Please refer to Figure 5 As shown, the cleaning mechanism 6 also includes a fifth electric push rod 607 and a second scraper 608. The fifth electric push rod 607 is fixedly installed on the inside left side of the housing 1, and the second scraper 608 is fixedly connected to the output end of the fifth electric push rod 607. The outer diameter of the second scraper 608 is adapted to the inner diameter of the liquid outlet pipe 207.

[0035] Those skilled in the art will understand that by controlling the output end of the third stepper motor 603 to rotate, the third lead screw 601 rotates, thereby driving the L-shaped plate 604 to move horizontally back and forth along the outer wall of the third guide rod 602, thereby driving the first scraper 606 to move horizontally back and forth. Furthermore, by controlling the output end of the fourth electric push rod 605 to extend or retract, the first scraper 606 is driven to move downward or upward. In addition, by controlling the extension or retraction of the output end of the fifth electric push rod 607, the second scraper 608 can be driven to move upward or downward.

[0036] To clearly describe the working principle of this invention, we will use... Figure 1 This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. Initially, both sets of mold bodies are in the mold-closed state. Under the combined action of the output end of the second stepper motor 303 and the output end of the multi-stage electric telescopic rod 305, the two sets of first bevel gears 309 on the mold frame 306 on the left side and the two sets of second bevel gears 402 on the rotating rod 401 mesh respectively. S2. By controlling the coordinated action of the output ends of the second electric push rod 504 and the first electric push rod 502, the key 510 is positioned directly above the lock hole of the lock 311. Then, by driving the output end of the third electric push rod 508 to extend, the key 510 moves downward and is inserted into the lock hole of the lock 311. Then, by driving the output end of the third drive motor 506 to drive the drive gear 507 to rotate, the driven gear 509 and the third electric push rod 508 rotate as a whole, thus driving the key 510 to rotate. This disconnects the mold top plate 310 from the left mold side plate 308. In addition, the center of the second drive motor 501 and the center of rotation of the mold top plate 310 around the top of the right mold side plate 308 are on the same straight line. Therefore, by driving the output end of the second drive motor 501 to rotate, the mold top plate 310 rotates upward 90 degrees to a vertical state. This state is called the mold opening state. S3. The output end of the first stepper motor 204 drives the first lead screw 202 to rotate, causing the movable part 205 to move to the right along the outer wall of the first guide rod 203, thereby driving the heating cylinder 206 and the liquid outlet pipe 207 to move to the right as a whole. The liquid outlet pipe 207 is located above the mold on the left side. A high-temperature heating plate is embedded in the inner wall of the heating cylinder 206, which can heat the metal raw material at high temperature to form molten metal liquid. By controlling the opening of the liquid outlet valve 208, the molten metal liquid flows into the mold. S4. The output end of the first stepper motor 204 rotates in the opposite direction, driving the heating cylinder 206 and the liquid outlet pipe 207 to move to the left to reset. Under the action of the second auxiliary mechanism 5, the mold top plate 310 is driven to rotate to close the mold, and the key 510 is rotated to lock the lock 311. The mold frame 306, the mold side plate 308 and the mold top plate 310 are all equipped with water cooling pipe systems. The molten liquid inside cools and forms a die casting. Since the cooling and forming takes a certain amount of time, the above steps are repeated in the same way during this time interval. The mold body on the right side can be opened, injected and closed. This improves the processing efficiency. S5. After the die-cast part is formed in the left mold body, it returns to the injection position, that is, the two sets of first bevel gears 309 on it and the two sets of second bevel gears 402 on the rotating rod 401 respectively mesh. Under the action of the second auxiliary mechanism 5, the mold top plate 310 is rotated 90 degrees upward to a vertical state. After the key 510 is pulled out, the mold top plate 310 is still in this position. Then, by controlling the output end of the first drive motor 403 to rotate, the rotating rod 401 and the two sets of second bevel gears 402 are rotated as a whole, so that the two sets of mold side plates 308 are respectively unfolded outward to a horizontal state. The inner wall of the mold side plate 308 and the inner bottom of the mold frame 306 are on the same straight line. S6. Under the combined action of the output end of the third stepper motor 603 and the output end of the fourth electric push rod 605, the bottom of the first scraper 606 is made to fit against the inner wall of the mold side plate 308 in the horizontal state. The first scraper 606 is located on the left side of the die-cast part. The first scraper 606 moves to the right, thereby pushing the die-cast part onto the screening plate 107 on the one hand, and cleaning the inner walls of the two sets of mold side plates 308 and the inner wall of the mold frame 306 in the horizontal state on the other hand. The vibration motor 108 is started, causing the screening plate 107 to shake, which can also shake off the solidified raw material that falls on the top of the screening plate 107 after scraping. The output end of the cylinder 109 retracts upward, driving the cover plate 110 to move upward, and the die-cast part slides onto the external conveyor. Similarly, the mold body on the right side is also discharged in this way, thereby realizing automated production without manual assistance. S7. If it is necessary to clean the inside of the liquid outlet pipe 207, in order to prevent the solidified raw material from causing blockage, move the liquid outlet pipe 207 directly above the second scraper 608. The output end of the fifth electric push rod 607 extends or retracts, and the second scraper 608 moves up and down to clean it. Finally, all the scraped solidified raw material can slide down through the inclined bottom plate 101 into the bucket body 102 and enter the inside of the pipe body 104. Under the action of the screw conveyor shaft 105, it re-enters the heating cylinder 206 for heating and melting, thus avoiding waste of raw materials.
