Description
Technical Field
[0001] The invention belongs to the technical field of casting and relates to an intelligent casting device for vehicle accessories. Background Art
[0002] Smart casting reduces labor intensity and improves production efficiency through automated equipment. With the continuous advancement of technology and the gradual expansion of its applications, smart casting will become the future development direction of the foundry industry. Smart casting is one of the most important technologies in the current production of automotive parts.
[0003] The patent document with publication number CN118558990A discloses an aluminum alloy frame pressure casting device, comprising an upper die base, a lower die base, a die core fixed on the upper die base, a die cavity fixed on the lower die base, and guide pillars fixed on the four corners of the lower die base, the four corners of the upper die base are provided with guide holes that slide fit on the four guide pillars; the die cavities are two symmetrical on the left and right, and the die cores correspond to the two die cavities. A first slide rail is provided on the bottom surface of the left die cavity, and the first slide rail slides fit on the track on the left, so that two frames can be cast at one time, thereby improving work efficiency. When the two die cavities share a solution feed channel and are fed into the two die cavities at the same time and cast into frames, the two frames can be quickly divided at the common feed channel through the front-and-rear discharge method of the two die cavities, saving the feed channel, improving the feeding efficiency of the aluminum alloy solution before casting, and also improving the casting efficiency.
[0004] However, the casting device has the following shortcomings when in use: by making the two mold cavities discharge in a front-and-rear manner, the two frames are quickly separated at the common feed channel. When the two mold cavities move relative to each other, the feed channel port is squeezed by the metal in the feed channel, which can easily cause wear or damage to the feed channel port, affecting the quality of subsequent casting, and when the metal at the fracture moves relative to the other mold cavity, it causes wear of the mold cavity, affecting the coordination of the two mold cavities.
[0005] In order to solve the above problems, the present invention proposes an intelligent casting device for vehicle accessories. Summary of the Invention
[0006] In order to solve the problems existing in the background technology, the present invention proposes an intelligent casting device for vehicle accessories.
[0007] In order to achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows: an intelligent casting device for vehicle accessories, comprising a mounting frame, an upper template and a lower template cooperating with the upper template, the upper template being mounted on the mounting frame for vertical movement, and a liquid injection hopper being provided in the middle of the upper template; the lower template has two, a square block being slidably mounted on the lower template, the square block being fixedly connected to a first rotating shaft, and the first rotating shaft being rotatably connected to the mounting frame; lower mold grooves are provided on the upper and lower end surfaces of the lower template, a first flow channel communicating with the lower mold groove is provided on the lower template, and the first flow channel cooperates with the liquid injection hopper; a linkage component is provided between the upper template and the first rotating shaft, the upper template is away from the lower template, and under the action of the linkage component, the first rotating shaft rotates, the lower template rotates, and the rotation directions of the two lower templates are opposite; an ejection component is slidably provided in the lower template, and when the upper template moves close to the lower template, the casting is ejected by the ejection component.
[0008] Furthermore, a second flow channel is opened on the lower mold plate, one end of the second flow channel is connected to the first flow channel, and the other end of the second flow channel is connected to the lower mold groove; the cross-sectional area of the first flow channel is smaller than the cross-sectional area of the second flow channel;
[0009] The cross section of the second flow channel is square, and the cross section of the first flow channel is arc-shaped.
[0010] Furthermore, the ejection assembly includes a push rod and a pressure rod; a second through hole is provided on the lower template, and the push rod is slidably arranged in the second through hole; a first through hole is provided on the lower template, and the pressure rod is slidably arranged in the first through hole; the push rod and the pressure rod are connected by a connecting piece; when the upper template moves close to the lower template, the upper template squeezes the pressure rod, causing the pressure rod to move downward, and the pressure rod pushes the push rod downward through the connecting piece, thereby ejecting the casting.
[0011] Furthermore, the connecting part includes a sliding block, a connecting plate and a sliding rod; the pressure rod is fixedly connected to the sliding block, the push rod is fixedly connected to the sliding rod, and the connecting plate is fixedly connected to the sliding block and the sliding rod; a first cavity connected to the first through hole is opened on the lower template, and the sliding block is slidably arranged in the first cavity; a second cavity connected to the first cavity and the second through hole is opened in the lower template, the connecting plate is slidably arranged in the second cavity, and the sliding rod is slidably arranged in the second through hole.
[0012] Furthermore, a limiting assembly is provided between the square block and the lower template, and the limiting assembly includes a first clamping block and a second clamping block; the first clamping block and the second clamping block are elastically slidably arranged on the square block, and a first clamping hole and a second clamping hole are opened on the lower template; the first clamping hole cooperates with the second clamping block, and the second clamping hole cooperates with the first clamping block.
[0013] Furthermore, an unlocking piece is provided on the sliding block, and the unlocking piece includes a first pushing block and a second pushing block, the first pushing block and the second pushing block are both elastically slidably arranged on the sliding block, and a slope is provided on the side where the first pushing block and the second pushing block are close to each other; the first pushing block cooperates with the first clamping hole, and the second pushing block cooperates with the second clamping hole; when the second clamping block extends into the first clamping hole, the lower template is limited; the sliding block slides along the first cavity, so that the first pushing block is inserted into the first clamping hole and the second clamping block is retracted into the square block, thereby releasing the limitation on the lower template; when the first clamping block extends into the second clamping hole and limits the lower template, the sliding block slides along the first cavity, so that the second pushing block is inserted into the second clamping hole and the first clamping block is retracted into the square block, thereby releasing the limitation on the lower template.
[0014] Furthermore, the first clamping hole and the second clamping hole are not on the same vertical plane.
[0015] In this way, when the template slides downward along the square block, the second clamping block is prevented from extending into the second clamping hole, or the first clamping block is prevented from extending into the first clamping hole, which affects the smooth progress of the casting operation.
[0016] Furthermore, a slide groove is provided on the lower template, and a limiting groove is provided on the inner wall of the slide groove; a protrusion is fixedly installed on the square block; the square block is slidably arranged in the slide groove, and the protrusion is slidably arranged in the limiting groove.

[0018] The upper template moves upward, and the hydraulic rod drives the rack upward through the connecting rod. At this time, the rack is not engaged with the gear, so that the lower template has enough rotation space.
[0019] When the upper template moves upwards a certain distance, the rack and the gear mesh. Then, as the upper template continues to move upwards, the rack drives the gear to rotate, and the gear drives the second shaft to rotate through the one-way bearing, and then the worm rotates, and the worm drives the worm wheel to rotate, so that the first shaft rotates, the first shaft drives the square block to rotate, and the square block drives the lower template to rotate.
[0020] The upper template moves downward. During the downward movement of the upper template, when the rack engages with the gear, the rack drives the gear to rotate, and the gear drives the outer ring of the one-way bearing to rotate relative to the inner ring. The second rotating shaft does not move, thereby preventing the lower template from rotating.
[0021] Furthermore, a hydraulic rod is fixedly mounted on the mounting frame, and an output end of the hydraulic rod is vertically downward and fixedly connected to the upper template.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] As the upper mold plate moves upward and away from the lower mold plate, the linkage assembly causes the lower mold plate to rotate, twisting the casting portion in the first flow channel and disconnecting the two castings, thereby reducing damage to the lower mold plate. Simultaneously, the casting is moved downward, facilitating its drop.
[0024] The upper mold plate then moves downward, closer to the lower mold plate. The upper mold plate pushes the ejector assembly, which ejects the casting. As the sliding block slides downward, the lower mold plate is released from its restraints, allowing it to move downward along the square block until the first retaining block enters the second retaining hole. This aligns the first runner corresponding to the second lower mold groove with the first rotating shaft, preparing for another casting.
[0025] Only by controlling the up and down movement of the upper template can the casting be broken, demoulded, blanked, and the upper and lower templates be matched. The high level of automation improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0046] like Figures 1-18 As shown, the technical solution adopted by the present invention is as follows: an intelligent casting device for vehicle parts includes a mounting frame 1, an upper template 3, and a lower template. The upper template 3 is mounted on the mounting frame 1 for vertical movement. A hydraulic rod 2 is fixedly mounted on the mounting frame 1, with the output end of the hydraulic rod 2 pointing vertically downward. The upper template 3 is fixedly connected to the output end of the hydraulic rod 2.
[0047] There are two lower templates, which are symmetrically rotatably mounted on the mounting frame 1 , and both lower templates are matched with the upper template 3 .
[0048] like Figure 8 、 Figure 15 As shown, the lower mold groove 25 is provided on both the upper and lower end surfaces of the lower mold. The first runner 34 and the second runner 35 are provided on both the upper and lower end surfaces of the lower mold. One end of the second runner 35 is connected to the first runner 34 on the same side, and the other end of the second runner 35 is connected to the lower mold groove 25 on the same side. A liquid injection hopper 4 that cooperates with the first runner 34 is installed on the upper mold 3. When the upper mold 3 and the lower mold are matched, the corresponding two first runners 34 on the two lower molds are connected. The high-temperature molten liquid is injected into the liquid injection hopper 4, and the high-temperature molten liquid flows into the lower mold groove 25 through the first runner 34 and the second runner 35 for casting and molding, thereby casting vehicle accessories.
[0049] After cooling and forming, the castings in the two lower mold cavities 25 are connected. The two lower mold plates are rotated 180 degrees in opposite directions, thereby twisting off the casting portion in the first runner 34, disconnecting the castings in the two lower mold cavities 25. The castings are now located below the lower mold plates.
[0050] The second runner 35 has a square cross-section, while the first runner 34 has an arcuate cross-section. The cross-sectional area of the first runner 34 is smaller than that of the second runner 35. The design of the first runner 34 ensures that while it can deliver high-temperature molten metal to the two lower mold cavities 25, it also allows the casting portion within the first runner 34 to be twisted off when the two lower mold plates rotate, thereby disconnecting the two castings.
[0051] The left and right ends of the mounting frame 1 are both rotatably mounted with first rotating shafts 5. Each first rotating shaft 5 is fixedly connected with a square block 14. The two square blocks 14 correspond to the two lower templates one by one, and the square blocks 14 are slidably connected to the corresponding lower templates up and down.
[0052] Specifically, the lower template is provided with a chute 16, and a limit groove 17 is defined on the inner wall of chute 16. A protrusion 15 is fixedly mounted on the square block 14. The square block 14 slides within the chute 16, and the protrusion 15 slides within the limit groove 17. This allows the square block 14 to slide within the chute 16, allowing the lower template to slide stably along the square block 14.
[0053] A limiting assembly is provided between the square block 14 and the lower template. The limiting assembly includes a first clamping block 18 and a second clamping block 19. The first clamping block 18 and the second clamping block 19 are both elastically slidably arranged on the square block 14. A first clamping block clearance groove and a second clamping block clearance groove are provided on the square block 14. The first clamping block 18 is slidably arranged in the first clamping block clearance groove, and the second clamping block 19 is slidably arranged in the second clamping block clearance groove. A first spring 20 is provided in each of the first clamping block clearance groove and the second clamping block clearance groove. The first spring 20 in the first clamping block clearance groove is fixedly connected between the end wall of the first clamping block clearance groove and the first clamping block 18. The first spring 20 in the second clamping block clearance groove is fixedly connected between the end wall of the second clamping block clearance groove and the second clamping block 19.
[0054] The lower template is provided with a first retaining hole 38 and a second retaining hole 39. The first retaining hole 38 engages with the second retaining block 19, and the second retaining hole 39 engages with the first retaining block 18. When the square block 14 is at one end of the lower template, the second retaining block 19 inserts into the first retaining hole 38, securing the lower template. When the square block 14 is at the other end of the lower template, the first retaining block 18 inserts into the second retaining hole 39, securing the lower template.
[0055] A linkage assembly is provided between each first rotating shaft 5 and the upper template 3. When the upper template 3 moves upward, that is, moves away from the lower template, under the action of the linkage assembly, the first rotating shaft 5 rotates, and the first rotating shaft 5 drives the lower template to rotate through the square block 14.
[0056] like Figure 2 、 Figure 3 As shown, the linkage assembly includes a rack 13, a gear 11, a worm 9, and a worm wheel 6. The upper template 3 is fixedly connected to a connecting rod 12, which is arranged vertically. The rack 13 is fixedly connected to the lower end of the connecting rod 12. A lug 7 is fixedly mounted on the mounting frame 1, and a second rotating shaft 8 is rotatably mounted on the lug 7. The gear 11 is mounted on the second rotating shaft 8 via a one-way bearing 10. The worm 9 is coaxially fixedly connected to the second rotating shaft 8. The worm wheel 6 is coaxially fixedly connected to the first rotating shaft 5. The worm wheel 6 and the worm 9 are meshed.
[0057] When the upper template 3 moves upward, the rack 13 meshes with the gear 11, which drives the second rotating shaft 8 to rotate via the one-way bearing 10. The second rotating shaft 8 drives the worm 9 to rotate, which drives the worm wheel 6 to rotate, thereby rotating the first rotating shaft 5. The first rotating shaft 5 drives the lower template to rotate via the square block 14. When the upper template 3 moves upward and the rack 13 meshes with the gear 11, the gear 11 drives the outer ring of the one-way bearing 10 to rotate relative to the inner ring. The second rotating shaft 8 does not move, and thus the lower template does not rotate.
[0058] Each lower template is equipped with an ejector assembly. When the upper template 3 moves downward, it acts on the ejector assembly, which ejects the casting, completes the demoulding of the casting, and makes the casting fall, completing the blanking of the casting.
[0059] like Figure 9 、 Figure 10 、 Figure 11 As shown, the ejection assembly includes a push rod 30 and a pressure rod 27. The push rod 30 and the pressure rod 27 are connected via a connecting member. The connecting member includes a sliding block 26, a connecting plate 28 and a sliding rod 29.
[0060] One end of the connecting plate 28 is fixedly connected to the slide bar 29, and the other end of the connecting plate 28 is fixedly connected to the slide block 26. The upper and lower ends of the slide bar 29 are fixedly connected to the push rod 30. The upper and lower ends of the slide block 26 are fixedly connected to the pressure rod 27.
[0061] The lower mold plate defines a second through-hole 24, which connects the two lower mold slots 25. The lower mold plate defines a second cavity 23 and a first cavity 21. One end of the second cavity 23 connects to the second through-hole 24, and the other end of the second cavity 23 connects to the first cavity 21. First through-holes 22 are defined at both the upper and lower ends of the first cavity 21.
[0062] The slide bar 29 is slidably disposed in the second through hole 24, and the push rod 30 is sealingly slidably disposed in the second through hole 24. The connecting plate 28 is slidably disposed in the second cavity 23, the sliding block 26 is slidably disposed in the first cavity 21, and the pressure rod 27 is slidably disposed in the corresponding first through hole 22.
[0063] When the upper and lower mold plates 3 are mated, the upper compression rods 27 extend into the first through-holes 22, while the lower compression rods 27 extend outside the lower mold plate. This causes the upper mold plate 3 to move upward, which in turn causes the lower mold plate to rotate 180 degrees about the first rotation axis 5. The upper mold plate 3 then moves downward, squeezing the corresponding compression rods 27, causing the ejector assembly to eject the casting.
[0064] The sliding block 26 is provided with an unlocking member. The unlocking member includes a first push block 31 and a second push block 33. The first push block 31 and the second push block 33 are elastically slidably disposed on the sliding block 26. Specifically, the sliding block 26 is provided with a first push block clearance groove and a second push block clearance groove. The first push block 31 is slidably disposed in the first push block clearance groove, and the second push block 33 is slidably disposed in the second push block clearance groove. A second spring 32 is fixedly connected to each of the first push block clearance groove and the second push block clearance groove, and the first push block 31 and the second push block 33 are fixedly connected to the corresponding second spring 32.
[0065] The first push block 31 engages with the first locking hole 38, and the second push block 33 engages with the second locking hole 39. When the second locking block 19 extends into the first locking hole 38 to limit the lower template, the second push block 33 extends into the second locking hole 39. At this time, the elastic force of the second spring 32 is greater than the elastic force of the first spring 20. The pressure rod 27 pushes the sliding block 26 to slide along the first cavity 21, and the second push block 33 retracts into the second push block's clearance groove. When the first push block 31 and the first locking hole 38 are opposite each other, the first push block 31 extends into the first locking hole 38 under the action of the corresponding second spring 32. The first push block 31 pushes the second locking block 19, causing the second locking block 19 to overcome the elastic force of the first spring 20 and retract into the square block 14. This releases the limit on the lower template, allowing the lower template to slide along the square block 14. Until the first clamping block 18 and the second clamping hole 39 are opposite to each other, the first clamping block 18 extends into the second clamping hole 39 under the action of the first spring 20 to limit the lower template.
[0066] The first push block 31 and the second push block 33 are both provided with inclined surfaces on their adjacent sides so as to allow the first push block 31 or the second push block 33 to retract into the sliding block 26 and allow the sliding block 26 to slide smoothly along the first cavity 21 .
[0067] The first clamping hole 38 and the second clamping hole 39 are not on the same vertical plane. In this way, when the lower template slides downward along the square block 14, the second clamping block 19 is prevented from extending into the second clamping hole 39, or the first clamping block 18 is prevented from extending into the first clamping hole 38, which affects the smooth progress of the casting operation.
[0068] Working principle: Initially, Figure 17As shown, the second locking block 19 extends into the first locking hole 38 under the action of the first spring 20, and the second push block 33 extends into the second locking hole 39 under the action of the second spring 32. For ease of description, in this embodiment, the two lower die grooves 25 on the same lower die plate are designated as the first lower die groove 2501 and the second lower die groove 2502, respectively. Initially, the first lower die groove 2501 is located above the lower die plate, and the second lower die groove 2502 is located below the lower die plate. The two lower die plates are designated as the first lower die plate 36 and the second lower die plate 37, respectively. The first lower die grooves 2501 on the first lower die plate 36 and the second lower die plate 37 both mate with the upper die plate 3. At this point, the axis of the first runner 34 corresponding to the first lower die groove 2501 is coaxial with the first rotating shaft 5. The pressure rod 27 on the same side as the first lower die groove 2501 extends into the lower die plate, while the pressure rod 27 on the same side as the second lower die groove 2502 extends below the lower die plate.
[0069] The high temperature molten metal is poured into the liquid injection hopper 4, and the high temperature molten metal flows into the lower die groove 25 through the first flow channel 34 and the second flow channel 35 for casting. The two castings after molding are connected together.
[0070] After the casting gradually cools down, the hydraulic rod 2 is started, and the hydraulic rod 2 drives the upper template 3 to move up. The hydraulic rod 2 drives the rack 13 to move up through the connecting rod 12. At this time, the rack 13 is not engaged with the gear 11. This allows the lower template to have enough rotation space.
[0071] After the upper template 3 moves upward a certain distance, the rack 13 engages with the gear 11. Then, as the upper template 3 continues to move upward, the rack 13 drives the gear 11 to rotate, and the gear 11 drives the second rotating shaft 8 to rotate through the one-way bearing 10, and then the worm 9 rotates, and the worm 9 drives the worm wheel 6 to rotate, causing the first rotating shaft 5 to rotate, and the first rotating shaft 5 drives the square block 14 to rotate, and the square block 14 drives the lower template to rotate. The lower template rotates around the first rotating shaft 5, and the rotation directions of the two lower templates are opposite, so that the casting part in the first flow channel 34 is twisted off, causing the two castings to be disconnected. Since the cross-sectional area of the first flow channel 34 is small, the casting part in the first flow channel 34 is easily twisted off. Since the first flow channel 34 is coaxially arranged with the first rotating shaft 5, it is beneficial to reduce the damage caused to the lower template by the two castings when disconnected, which helps to increase the service life of the lower template.
[0072] When the rack 13 is disengaged from the gear 11, the lower template rotates 180 degrees. Figure 18 As shown, at this time, the first lower mold groove 2501 is downward, the second lower mold groove 2502 is upward, and the pressing rod 27 corresponding to the second lower mold groove 2502 is located above the lower mold plate.
[0073] Afterwards, the hydraulic rod 2 is extended to move the upper template 3 downward. During the downward movement of the upper template 3, when the rack 13 engages with the gear 11, the rack 13 drives the gear 11 to rotate, and the gear 11 drives the outer ring of the one-way bearing 10 to rotate relative to the inner ring. The second rotating shaft 8 does not move, and the lower template does not rotate.
[0074] The upper template 3 squeezes the pressure rod 27 corresponding to the second lower mold groove 2502. At this time, since the lower template is limited by the second clamping block 19, the lower template cannot move downward. The second push block 33 disengages from the second clamping hole 39 and retracts into the sliding block 26. The sliding block 26 moves downward along the first cavity 21, and the connecting plate 28 moves downward in the second cavity 23. The slide rod 29 moves downward. The slide rod 29 pushes the casting in the first lower mold groove 2501 downward through the push rod 30, pushes the casting in the first lower mold groove 2501 out, completes the demoulding of the casting, and makes the casting in the first lower mold groove 2501 fall.
[0075] When the pressure rod 27 corresponding to the second lower mold groove 2502 retracts into the lower mold plate, the pressure rod 27 corresponding to the first lower mold groove 2501 extends out from the bottom of the lower mold plate. At this time, the ejection assembly cannot continue to move downward, and at this time the first push block 31 is opposite to the first clamping hole 38. The first push block 31 extends into the first clamping hole 38 under the action of the second spring 32. The first push block 31 pushes the second clamping block 19 in the first clamping hole 38 back into the square block 14, thereby releasing the limit on the lower mold plate.
[0076] The upper mold plate 3 then continues to move downward, pushing the lower mold plate downward. The lower mold plate then moves downward along the square block 14 until the first latch 18 is aligned with the second latch hole 39. Under the action of the first spring 20, the first latch 18 extends into the second latch hole 39, securing the lower mold plate. At this point, the first flow channel 34 corresponding to the second lower mold groove 2502 is coaxial with the first rotating shaft 5. The second lower mold groove 2502 on the sliding block 26 and the pressure rod 27 now engages with the upper mold plate 3.
[0077] When the lower template moves downward along the square block 14, since the second clamping hole 39 and the first clamping hole 38 are not on the same vertical plane, the second clamping block 19 is prevented from being inserted into the second clamping hole 39, so that the lower template can continue to move downward until the first clamping block 18 is opposite to the second clamping hole 39, so that the first clamping block 18 extends into the second clamping hole 39, and then the first flow channel 34 corresponding to the second lower mold groove 2502 is coaxial with the first rotating shaft 5.
[0078] Similarly, high-temperature liquid is injected into the liquid injection hopper 4, and the high-temperature liquid flows into the second lower mold groove 2502 through the first flow channel 34 and the second flow channel 35 for casting.
[0079] As the upper mold plate 3 moves upward and away from the lower mold plate, the linkage assembly causes the lower mold plate to rotate, twisting the portion of the casting within the first runner 34, disconnecting the two castings and simultaneously moving the casting downward to facilitate its drop. The upper mold plate 3 then moves downward, closer to the lower mold plate, pushing the ejector assembly, which ejects the casting. Furthermore, as the sliding block 26 slides downward, the restraint on the lower mold plate is released, allowing the lower mold plate to move downward along the square block 14 until the first locking block 18 extends into the second locking hole 39. This, in turn, aligns the first runner 34 corresponding to the second lower mold groove 2502 with the first rotating shaft 5, preparing for the next casting.
[0080] When the upper mold plate 3 moves upward, the device separates the two castings through a linkage assembly, simultaneously preparing them for removal. When the upper mold plate 3 moves downward, it squeezes the ejection assembly, ejecting the casting and preparing it for the next casting operation. This improves the automation level of the casting process and contributes to improving casting efficiency. Simply controlling the up and down movement of the upper mold plate 3 allows for the separation, demolding, and blanking of the casting, as well as the coordination between the upper mold plate 3 and the lower mold plate. This high level of automation improves production efficiency.
