Description

Technical Field

[0001] This invention relates to the field of automotive mechanical parts manufacturing technology, specifically to a rapid die-casting device for automotive mechanical parts manufacturing. Background Technology

[0002] Die-casting equipment used in the production of automotive mechanical parts involves injecting molten metal into a mold and pressing it into shape under high pressure. This equipment is widely used in the automotive industry, particularly for producing lightweight metal parts made of aluminum, zinc, and magnesium alloys. Die-casting equipment can efficiently and precisely produce parts with complex shapes and stable dimensions, suitable for engine components, gearbox housings, chassis components, and body structural parts.

[0003] Patent publication number CN219074325U relates to a rapid die-casting device for producing automotive mechanical parts. The device includes a fixed mold with a mold groove on its right side. A movable mold is located on the right side of the fixed mold. A metal collar is fitted onto the outer surface of the movable mold, and the outer surface of the metal collar contacts the inner wall of the mold groove. Two fixing plates are fixedly connected to the outer surface of the fixed mold. A fixing cover is fixedly embedded on the side of each fixing plate that is close to each other. Electric push rods are fixedly connected to the inner walls of each of the two fixing covers. Arc-shaped clamping plates are fixedly connected to the telescopic ends of each of the two electric push rods. A warning sign is fixedly installed on the front of the movable mold, and two sets of connecting columns are fixedly connected to the right side of the movable mold. This die-casting mold for producing automotive parts facilitates the unloading of metal collars, achieving automated mechanical unloading and avoiding the safety hazard of burns from high temperatures during manual unloading of automotive parts.

[0004] In the aforementioned patent, the setting of the moving mold facilitates the unloading of metal collars, achieving the effect of automatic mechanical unloading and avoiding the safety hazard of being burned by high temperature when manually unloading automotive parts. However, automotive parts may get stuck in the mold. Therefore, a rapid die-casting device for the production of automotive mechanical parts with demolding function is designed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rapid die-casting device for the production of automotive mechanical parts, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a rapid die-casting device for the production of automotive mechanical parts, comprising a machine body, a sliding plate slidably mounted on the upper part of the machine body, a fixed plate fixedly mounted on the upper part of the machine body, a motor fixedly mounted on the right side of the fixed plate, an electric push rod fixedly mounted on the upper part of the machine body, a push block fixedly mounted on the output end of the electric push rod, and further comprising a demolding device, a storage device, and a water cooling device; The demolding device includes a mold, which is fixedly installed on the side of the slide plate one near the fixed plate. A fixing block one is fixedly installed on the side of the fixed plate near the slide plate one. A liquid inlet pipe is fixedly inserted through the fixing block one, and a liquid inlet is opened above the liquid inlet pipe. A trapezoidal plate is fixedly installed on the side of the fixing block one near the slide plate one. A trapezoidal groove is opened on the side of the mold near the fixed plate. A slide plate two is slidably installed inside the trapezoidal groove. A spring one is provided between the slide plate two and the bottom of the trapezoidal groove. A ejector block is fixedly installed on the side of the slide plate two near the fixed plate. During the separation process, the slide plate two moves towards the direction of the fixing block one under the reset action of the spring one. The movement of the slide plate two drives the ejector block to move, pushing out the molded car part, achieving a demolding effect and preventing the car part from getting stuck inside the mold.

[0007] According to the above technical solution, the pusher block is slidably installed inside the liquid inlet pipe, and the liquid inlet pipe is fixedly inserted inside the fixed plate. The trapezoidal plate will eventually slide completely into the trapezoidal groove to avoid affecting the fit between the mold and the fixed block, which could lead to leakage of molten metal.

[0008] According to the above technical solution, the storage device includes a round rod, a rotating plate rotatably mounted on the circumference of the round rod, a guide groove above the rotating plate, a collecting plate slidably mounted below the fixing block, a storage groove above the collecting plate, a fixing block two fixedly mounted on the side of the mold near the fixing plate, a groove one on the side of the fixing block near the sliding plate, and a groove two on the side of the mold near the fixing plate. Under the action of relative motion force, the rotating plate rotates counterclockwise around the round rod until it reaches a horizontal position. When the sliding plate moves away from the fixing plate, the ejector block may push the car parts out and drop them into the guide groove above the rotating plate which has already rotated to a horizontal position, thus preventing the molded car parts from falling into the machine body and causing impact damage to the car parts. The collecting plate is slidably mounted to facilitate the removal of the car parts.

[0009] According to the above technical solution, the side of the rotating plate near the mold is set as an inclined surface, and the side of the second fixed block near the first fixed block is set as an inclined surface. As the second fixed block moves slowly, its inclined surface will first come into contact with the inclined surface of the rotating plate that is rotatably installed on the side of the first fixed block. The presence of the inclined surface will generate an interaction force.

[0010] According to the above technical solution, the fixing block 1 has a groove 1 for receiving the fixing block 2 on the side near the sliding plate 1, and the mold has a groove 2 for receiving the rotating plate and the round rod on the side near the fixing plate. The rotating plate slides into the groove 2 and the fixing block 2 slides into the groove 1, so as to avoid the rotating plate and the fixing block 2 affecting the fit between the mold and the fixing block 1, which would lead to leakage of molten metal and affect the shaping of the automotive parts.

[0011] According to the above technical solution, the water cooling device includes a water tank, which is fixedly installed on the side of the slide plate one near the fixed plate. A slide rod slides through the side of the water tank near the fixed plate. A slide plate three is fixedly installed on the end of the slide rod near the water tank. A spring two is provided between the slide plate three and the water tank on the side near the slide rod. A partition is fixedly installed in the middle of the water tank. A slide plate four is slidably installed on the side of the partition away from the slide plate three. A water pipe one is fixedly inserted through the top of the water tank. A water pipe two is fixedly inserted through the top of the water tank. An air vent is opened on the top of the water tank. A square groove is opened inside the mold. The movement of the slide rod drives the slide plate three to move. The movement of the slide plate three will squeeze the water inside the water tank. The squeezed water flows through the water pipe one into the square groove, and flows through the water pipe two into the water below the slide plate four on the right side of the partition, thus circulating the water and replacing the water inside the square groove. This provides better cooling for the molten metal and accelerates the molding of automotive parts.

[0012] According to the above technical solution, the slide plate three and slide plate four are slidably installed on both sides of the partition, and the air outlet is located above the slide plate four. The air above the slide plate four is discharged from the air outlet to balance the pressure of the upper and lower parts.

[0013] According to the above technical solution, the first water pipe is connected to the square trough, and the second water pipe is connected to the square trough, which facilitates water circulation and provides better cooling for the molten metal.

[0014] This invention provides a rapid die-casting apparatus for the production of automotive mechanical parts. It has the following advantages: (1) The rapid die casting device for producing automotive mechanical parts uses the movement of the trapezoidal block to drive the movement of the slide plate 2. The movement of the slide plate 2 squeezes the spring 1. During the separation process, the slide plate 2 moves towards the direction where the fixed block 1 is located under the reset action of the spring 1. The movement of the slide plate 2 drives the movement of the ejector block to eject the formed automotive parts, achieving a demolding effect and preventing the automotive parts from getting stuck inside the mold. The trapezoidal plate will eventually slide completely into the trapezoidal groove, preventing it from affecting the fit between the mold and the fixed block 1, which could lead to leakage of molten metal.

[0015] (2) The rapid die-casting device for producing automotive mechanical parts generates relative motion force through the interaction of inclined surfaces. Under the action of relative motion force, the rotating plate rotates counterclockwise around the round rod until it reaches the horizontal position. When the sliding plate moves away from the fixed plate, the top block may push the automotive parts out and fall into the guide groove opened above the rotating plate which has already turned to the horizontal position. This prevents the formed automotive parts from falling into the machine body and causing impact damage to the automotive parts. The collecting plate is slidably installed to facilitate the removal of the automotive parts. The rotating plate slides into the second groove and the second fixed block slides into the first groove to prevent the rotating plate and the second fixed block from affecting the fit between the mold and the first fixed block, which would cause the molten metal to leak and affect the shaping of the automotive parts.

[0016] (3) The rapid die-casting device for producing automotive mechanical parts uses the sliding rod to drive the sliding plate three to move. The movement of the sliding plate three will squeeze the water inside the water tank. The squeezed water flows through the water pipe one into the square groove, and through the water pipe two into the water below the right sliding plate four of the partition, to circulate the water and replace the water inside the square groove. This will have a better cooling effect on the molten metal and accelerate the molding of automotive parts. The water tank is divided into two parts by the middle partition. The water squeezed by the movement of the sliding plate three is the water on the left side of the partition. The right side of the partition has the sliding plate four installed. The upper part of the sliding plate four is air and the lower part is water. The water tank is located above the sliding plate four and has an air outlet. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 One embodiment of the present invention is: a rapid die-casting device for the production of automotive mechanical parts, including a body 1, a sliding plate 2 slidably mounted on the top of the body 1, a fixed plate 3 fixedly mounted on the top of the body 1, a motor 4 fixedly mounted on the right side of the fixed plate 3, an electric push rod 5 fixedly mounted on the top of the body 1, a push block 501 fixedly mounted on the output end of the electric push rod 5, and also including a demolding device, a storage device and a water cooling device. The demolding device includes a mold 6, which is fixedly installed on the side of the slide plate 2 near the fixed plate 3. A fixing block 7 is fixedly installed on the side of the fixed plate 3 near the slide plate 2. A liquid inlet pipe 502 is fixedly inserted through the fixing block 7, and a liquid inlet 503 is opened above the liquid inlet pipe 502. A trapezoidal plate 601 is fixedly installed on the side of the fixing block 7 near the slide plate 2. A trapezoidal groove 602 is opened on the side of the mold 6 near the fixed plate 3. A slide plate 603 is slidably installed inside the trapezoidal groove 602. A spring 604 is set between the bottom of the slide plate 603 and the bottom of the trapezoidal groove 602. A ejector block 605 is fixedly installed on the side of the slide plate 603 near the fixed plate 3. During the separation process, the slide plate 603 moves towards the fixed block 7 under the reset action of the spring 604. The movement of the slide plate 603 drives the ejector block 605 to move, ejecting the molded car parts and achieving a demolding effect, thus preventing the car parts from getting stuck inside the mold 6.

[0021] The pusher 501 is slidably installed inside the liquid inlet pipe 502, which is fixedly inserted through the fixed plate 3. The trapezoidal plate 601 will eventually slide completely into the trapezoidal groove 602 to avoid affecting the fit between the mold 6 and the fixed block 7, which could lead to leakage of molten metal.

[0022] In this embodiment, during operation: Motor 4 is started, pulling slide plate 1 2 towards fixed plate 3. Slide plate 1 2's movement drives mold 6. When it approaches fixed block 1 7, trapezoidal plate 601 first enters trapezoidal groove 602 and slides within it. As it moves to contact slide plate 2 603, it drives slide plate 2 603 to slide into mold 6. Slide plate 2 603's movement drives ejector block 605. Ejector block 605 engages with mold 6, without affecting the molding of automotive parts. Slide plate 2 603 compresses spring 1 604, and trapezoidal plate 601 eventually slides completely into trapezoidal groove 602, preventing it from affecting the fit between mold 6 and fixed block 1 7, thus avoiding molten metal leakage. When mold 6 moves to... When the fixing block 7 is in place, turn off the motor 4 and inject the molten metal into the inlet pipe 502 from the inlet 503. Start the electric push rod 5 to push the push block 501 towards the fixing block 7. The push block 501 pushes the molten metal into the mold 6. Start the electric push rod 5 to retract the push block 501 to avoid affecting the shaping of the molten metal. The molten metal is shaped in the mold 6 to obtain the required car parts. Start the motor 4 to push the sliding plate 2 to separate from the fixing plate 3. During the separation process, the sliding plate 2 603 moves towards the fixing block 7 under the reset action of the spring 604. The movement of the sliding plate 2 603 drives the ejector block 605 to move, ejecting the formed car parts and achieving a demolding effect to prevent the car parts from getting stuck inside the mold 6.

[0023] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the storage device includes a round rod 703, a rotating plate 701 rotatably mounted on the circumference of the round rod 703, a guide groove 702 opened above the rotating plate 701, a collecting plate 704 slidably mounted below the fixing block 7, a storage groove 705 opened above the collecting plate 704, a fixing block 706 fixedly mounted on the side of the mold 6 near the fixing plate 3, a groove 707 opened on the side of the fixing block 7 near the sliding plate 2, and a groove 708 opened on the side of the mold 6 near the fixing plate 3. Under the action of relative motion force, the rotating plate 701 rotates counterclockwise around the round rod 703 until it reaches a horizontal position. When the sliding plate 2 moves away from the fixing plate 3, the ejector block 605 may push the car parts out and fall into the guide groove 702 opened above the rotating plate 701 which has already rotated to a horizontal position, thus preventing the molded car parts from falling into the machine body 1 and causing impact damage to the car parts. The collecting plate 704 is slidably mounted to facilitate the removal of the car parts.

[0024] The side of the rotating plate 701 closest to the mold 6 is set as an inclined surface, and the side of the second fixed block 706 closest to the first fixed block 7 is set as an inclined surface. As the second fixed block 706 moves slowly, its inclined surface will first come into contact with the inclined surface of the rotating plate 701 which is rotatably mounted on the side of the first fixed block 7. The presence of the inclined surfaces will generate an interaction force.

[0025] The fixing block 7 has a groove 707 on the side near the sliding plate 2 for receiving the fixing block 706. The mold 6 has a groove 708 on the side near the fixing plate 3 for receiving the rotating plate 701 and the round rod 703. The rotating plate 701 slides into the groove 708 and the fixing block 706 slides into the groove 707. This prevents the rotating plate 701 and the fixing block 706 from affecting the fit between the mold 6 and the fixing block 7, which could lead to leakage of molten metal and affect the shaping of the automotive parts.

[0026] In this embodiment, when the sliding plate 2 moves towards the fixed plate 3, the mold 6 moves, causing the fixed block 706 to move. As the fixed block 706 moves slowly, its inclined surface first contacts the inclined surface of the rotating plate 701, which is rotatably mounted on the side of the fixed block 7. Under the action of relative motion force, the rotating plate 701 rotates counterclockwise around the round rod 703 until it reaches a horizontal position, and then slides into the groove 708. The fixed block 706 slides into the groove 707, preventing the rotating plate 701 and the fixed block 706 from affecting the fit between the mold 6 and the fixed block 7, which could lead to molten metal leakage and affect the shaping of the automotive parts. When the sliding plate 2 moves away from the fixed plate 3... The top block 605 may push the car parts out and fall into the guide groove 702 opened above the rotating plate 701 which has been rotated to a horizontal position below, to prevent the formed car parts from falling into the machine body 1 and causing impact damage to the car parts. When the slide plate 1 2 moves away from the fixed plate 3, the rotating plate 701 slides out from the groove 2 708. Since there is no limiting effect of the groove 2 708, the rotating plate 701 rotates clockwise under the action of gravity until it contacts the collecting plate 704 below. At this time, the car parts inside the guide groove 702 will slide into the storage groove 705 opened above the collecting plate 704. The collecting plate 704 is slidably installed to facilitate the removal of the car parts.

[0027] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the water cooling device includes a water tank 8, which is fixedly installed on the side of the sliding plate 1 2 near the fixed plate 3. A sliding rod 801 slides through the side of the water tank 8 near the fixed plate 3. A sliding plate 3 802 is fixedly installed on the end of the sliding rod 801 near the water tank 8. A spring 2 803 is provided between the side of the sliding plate 3 802 near the sliding rod 801 and the water tank 8. A partition 804 is fixedly installed in the middle of the water tank 8. A sliding plate 4 805 is slidably installed on the side of the partition 804 away from the sliding plate 3 802. A water cooling device is fixedly installed above the water tank 8. Pipe 1 (806) is fixedly connected to water tank 8 above water tank 8 via pipe 2 (807). A vent 808 is provided above water tank 8. A square groove 809 is provided inside mold 6. The movement of slide bar 801 drives slide plate 3 (802) to move. The movement of slide plate 3 (802) will squeeze the water inside water tank 8. The squeezed water flows through water pipe 1 (806) into square groove 809, and through water pipe 2 (807) into the water below slide plate 4 (805) on the right side of partition 804, thus circulating the water and replacing the water inside square groove 809. This provides better cooling for the molten metal and accelerates the molding of automotive parts.

[0028] Slide 3 802 and slide 4 805 are slidably installed on both sides of partition 804. Air outlet 808 is located above slide 4 805. Air above slide 4 805 is discharged through air outlet 808 to balance the pressure of the upper and lower parts.

[0029] Water pipe 1 806 is connected to square groove 809, and water pipe 2 807 is connected to square groove 809, which facilitates water circulation and provides better cooling for molten metal.

[0030] In this embodiment, during operation: when slide plate 1 2 moves towards fixed plate 3, it drives water tank 8 to move. The movement of water tank 8 drives slide rod 801 to move. Slide rod 801 first contacts fixed plate 3 and slides into water tank 8 under the action of fixed plate 3. The movement of slide rod 801 drives slide plate 3 802 to move. The movement of slide plate 3 802 squeezes the water inside water tank 8. Water tank 8 is divided into two parts by the middle partition 804. The water squeezed by slide plate 3 802 is the water on the left side of partition 804. Slide plate 4 805 is slidably installed on the right side of partition 804. Above slide plate 4 805 is air and below is water. The squeezed water flows through water pipe 1 806 into square tank 809, and through water pipe 2 807 into the water below slide plate 4 805 on the right side of partition 804, thus circulating the water. The square tank is then replaced. The water inside 809 provides better cooling for the molten metal, accelerating the molding of automotive parts. When water enters below slide plate 805, it pushes slide plate 805 upward. The air above slide plate 805 is discharged from the vent 808, balancing the pressure between the upper and lower parts. When slide plate 2 moves away from the fixed plate 3, slide plate 3 802 moves towards the fixed plate 3 under the reset action of spring 2 803, pulling the water in square groove 809 back into the water tank 8. To balance the pressure on both sides of the partition 804, the water below slide plate 805 flows into square groove 809 from water pipe 2 807. Slide plate 805 moves downward, and air enters above slide plate 805 from the vent 808, replacing the water inside square groove 809 again, greatly enhancing the cooling effect.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
