Description

Technical Field

[0001] This invention relates to the field of turbocharger die casting technology, specifically to a die casting apparatus for manufacturing turbocharger compressor housings. Background Technology

[0002] A turbocharger is actually an air compressor that increases the intake air volume of an engine by compressing air. It is a device used to improve engine power and is widely used in engines. The turbocharger housing is generally made by a die-casting device.

[0003] Chinese invention patent CN115383058A discloses a die-casting device for manufacturing turbocharger housings. The device includes a base, a frame, and a fixed mold frame. A support plate is positioned between the top of the frame and the fixed mold frame. The support plate is equipped with a lifting assembly, a lifting frame, two spraying mechanisms, and two shielding assemblies. Each spraying mechanism includes a spraying component and an adjustment component. The spraying angle of the spraying components is adjusted by the adjustment components, allowing the spraying components to spray the mold through angle changes. This ensures that the mold is evenly coated with release agent, improving the demolding effect of the turbocharger housing and solving the problem of burns or cracks in turbocharger housings due to uneven spraying of release agent within the mold, as seen in existing technologies. The two shielding assemblies prevent the release agent that is dispersed during the spraying process from being inhaled by workers, thus solving the technical problem of injury caused by workers inhaling the dispersed release agent.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: 1. The patent can spray release agent onto the mold through the spraying mechanism, but the die casting operation cannot continue when the spraying mechanism is working, which reduces the efficiency of die casting; 2. In the patent, the first rotary drive motor can drive the drive rod to rotate, and the second rotary drive motor can drive the swing rod to rotate, thereby realizing the rotation and left and right swing of the spraying component. However, this adjustment method will cause the pipes connected to the air gun nozzle to get tangled together, and there is even a risk of the pipes falling off or being damaged. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides a die-casting apparatus for manufacturing turbocharger compressor housings, thereby solving the problems mentioned in the background art regarding how to improve die-casting efficiency and avoid the risk of pipes getting tangled together.

[0011] Preferably, the swing mechanism includes two sliding seats, a swing rod, several first abutment blocks, and several second abutment blocks. Both ends of the swing rod are provided with arc surfaces. Each of the first and second abutment blocks is provided with two symmetrically arranged guide wedge surfaces. The two sliding seats are symmetrically arranged on the outer wall of the rotating cylinder. The swing rod is slidably arranged on the two sliding seats. The nozzle assembly is fixedly connected to the swing rod. All the first abutment blocks are arranged at equal angles along the circumference of the rotating cylinder on the inner side wall of one of the lower supports. All the second abutment blocks are arranged at equal angles along the circumference of the rotating cylinder on the inner wall of the other lower support. The second abutment blocks are located between two adjacent first abutment blocks.

[0012] Preferably, the air extraction mechanism includes an air tank, a synchronizing rod, and a driving assembly for driving the synchronizing rod to move left and right. A movable plug is slidably disposed inside the air tank, dividing the interior of the air tank into two air chambers. A discharge pipe is connected to the bottom middle of the air tank, and a collection cylinder is detachably disposed on the discharge pipe. Two ventilation pipes are disposed on the outer wall of the air tank, each communicating with one of the two air chambers. Solenoid valves are disposed on both the ventilation pipes and the discharge pipe. The air tank is fixedly connected to the bottom of the base. The synchronizing rod is slidably disposed on the air tank, and the synchronizing rod is coaxial with the air tank. One end of each of the two ventilation pipes is connected to one of the two die-casting cavities. The driving assembly is disposed at the bottom of the base and is drivenly connected to the two cover plates.

[0013] Preferably, the drive assembly includes a U-shaped rod, two guide seats, two L-shaped guide rods, and two transmission components. The two ends of the U-shaped rod are fixedly connected to the synchronous rod. The two guide seats are respectively disposed on the outer walls of both sides of the support frame. The two L-shaped guide rods are respectively slidably disposed on the two guide seats. One end of the two L-shaped guide rods is respectively fixedly connected to the top of the two cover plates.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Firstly, this invention employs two die-casting cavities. A synchronous frame is moved by a die-casting cylinder, allowing one die-casting cavity to perform die-casting operations while the other performs other operations without interference, thus improving die-casting efficiency. Secondly, a connecting pipe is used to deliver gas or release agent to the ventilation window, and then the gas or release agent is delivered to the rotating drum through the built-in groove. Subsequently, the gas or release agent can be sprayed out from the nozzle assembly. The rotating and swinging mechanisms still allow the nozzle assembly to rotate and swing, avoiding the risk of pipe entanglement and simplifying the structure.

[0018] Secondly, the present invention can drive the rotating drum to reciprocate clockwise and counterclockwise by pushing the cylinder. While the rotating drum is rotating, the cooperation between the swing rod, the first abutment block and the second abutment block synchronously drives all the jet heads to swing left and right. This not only simplifies the structure, but also gives the jet heads the functions of rotation and left and right swing.

[0019] Thirdly, the present invention drives the cover plate to rise and fall by means of a lifting electric push rod. While the cover plate is rising and falling, it can not only drive the closed door to rise and fall, but also drive the air extraction mechanism to work.

[0020] Fourth, the air extraction mechanism of the present invention can not only perform air extraction operation on the die casting cavity, but also perform air blowing operation on the die casting cavity, and air blowing can play an auxiliary role in cooling. Attached Figure Description

[0033] Please see Figure 1-9 The present invention will describe the above technical solution in detail through the following embodiments:

[0034] A die-casting device for manufacturing a compressor housing of a turbocharger, comprising a base 1. A support frame 2 is provided at the top of the base 1. Two die-casting cavities 21 are provided on the support frame 2. A material-taking window 22 and a closing component 3 for closing the material-taking window 22 are provided at one end of the die-casting cavity 21. A fixed mold frame 23 and a movable mold frame 24 are provided in the die-casting cavity 21. The two fixed mold frames 23 are located between the two movable mold frames 24. A die-casting cylinder is provided at one end of the support frame 2 away from the material-taking window 22. Guide chutes 25 are provided on both the upper and lower sides of the die-casting cylinder. A synchronizing frame 26 in a "Ji" shape is slidably provided on the two guide chutes 25. The output end of the die-casting cylinder is fixedly connected to the synchronizing frame 26. Linkage cantilever 261 is provided at both ends of the synchronizing frame 26. A linkage shaft 262 is provided on the linkage cantilever 261. Slide holes slidably matched with the linkage shaft 262 are provided on both sides of the support frame 2. The two linkage shafts 262 are respectively fixedly connected to the two movable mold frames 24. A gantry 4 is provided at the top of the support frame 2. Two symmetrically arranged lifting electric push rods 41 are provided on the gantry 4. A cover plate 42 is installed on the output end of the lifting electric push rod 41. Two symmetrically arranged lower support frames 43 are provided at the bottom of the cover plate 42. A rotating cylinder 45 is provided on the two lower support frames 43. Rotating shafts 46 are provided at both ends of the rotating cylinder 45. A number of groups of spray heads 47 are provided on the rotating cylinder 45. An internal cavity communicating with the rotating cylinder 45 is provided inside one of the rotating shafts 46. Ventilation windows 461 are provided on the outer wall of the rotating shaft 46. A rotating seat 431 rotatably matched with the rotating shaft 46 is provided on the outer wall of the lower support frame 43. A connecting pipe 432 is communicated and provided on one of the rotating seats 431. The connecting pipe 432 is communicated with the ventilation window 461. One end of the connecting pipe 432 penetrates through the cover plate 42, and a three-way joint 433 is further provided at one end of the connecting pipe 432. A rotating mechanism 5 for driving the rotating cylinder 45 to rotate is provided on the outer wall of one of the lower support frames 43. The rotating mechanism 5 is传动连接 with the other rotating shaft 46. A swinging mechanism 6 for driving the spray head group 47 to swing left and right is further provided on the rotating cylinder 45. The closing component 3 is传动连接 with the cover plate 42. Two square holes 27 matched with the cover plate 42 are provided at the top of the support frame 2. An air extraction mechanism 7 is provided at the bottom of the base 1. Both die-casting cavities 21 are communicated with the air extraction mechanism 7.

[0035] The present invention adopts two die-casting cavities 21. By driving the synchronizing frame 26 to move through the die-casting cylinder, when one die-casting cavity 21 is performing die-casting operations, the other die-casting cavity 21 can perform other operations without interference, virtually improving the die-casting efficiency. The connecting pipe 432 is used to输送气体或脱模剂 into the ventilation window 461, and then输送至 the rotating cylinder 45 through the internal groove. Subsequently, the gas or release agent can be sprayed out from the spray head group 47. Through the rotating mechanism 5 and the swinging mechanism 6, the spray head group 47 can still be rotated and swung, avoiding the risk of pipeline entanglement and simplifying the structure.

[0036] It should be noted that there are some inaccuracies in the original Chinese text, such as "传动连接" which is not a standard English expression. I have tried my best to translate it according to the context, but it may need to be further adjusted according to the accurate technical terms. Also, "输送气体或脱模剂" and "输送至" are not very clear in the context, and more accurate expressions may be needed to better convey the meaning.When using the device, a raw material is first placed into a die-casting cavity 21. Then, the die-casting cylinder drives the synchronous frame 26 to move. After the synchronous frame 26 moves, it drives one of the linkage shafts 262 to move into the die-casting cavity 21. The linkage shaft 262 drives the corresponding moving mold frame 24 to move synchronously. Then, the moving mold frame 24 and the fixed mold frame 23 cooperate to perform die-casting. The moving mold frame 24 in the other die-casting cavity 21 moves away from the fixed mold frame 23. The die-casting operation in the other die-casting cavity 21 is completed. After that, it is necessary to spray the release agent in this die-casting cavity 21. The lifting electric push rod 41 directly above the die-casting cavity 21 drives the cover plate 42 to move down. When the cover plate 42 moves down, it also drives the sealing component 3 to work.

[0037] The enclosure component 3 includes an enclosure door 31 and two guide frames 32. The top of the back of the enclosure door 31 is provided with a connecting suspension 33. The two guide frames 32 are symmetrically arranged on both sides of the material picking window 22. The enclosure door 31 is slidably disposed in the two guide frames 32. The connecting suspension 33 is fixedly connected to the cover plate 42.

[0038] When the cover plate 42 moves down, it causes the connecting suspension 33 to move down synchronously. The connecting suspension 33 causes the closing door 31 to move down synchronously within the two guide frames 32. The closing door 31 can move the material picking window 22 down. At this time, the cover plate 42 closes the square hole 27, and the die casting cavity 21 is in a closed state.

[0039] Of course, an observation window can be installed on the closed door 31 to facilitate observation of the inside of the die-casting cavity 21.

[0040] The release agent is then introduced into the rotating drum 45 through the three-way connector 433 and the connecting pipe 432, and then sprayed out by the nozzle assembly 47. The rotating mechanism 5 includes a pushing electric push rod 51, a pushing rack 52 and a driven gear 53. The pushing electric push rod 51 is set on the outer wall of one of the lower support frames 43, the pushing rack 52 is set on the output end of the pushing electric push rod 51, and the driven gear 53 is set on another rotating shaft 46. The driven gear 53 meshes with the pushing rack 52.

[0041] The nozzle assembly 47 includes several nozzles 471. The tail end of each nozzle 471 is provided with a flexible tube 472, which is connected to the rotating drum 45. The flexible tube 472 allows the nozzles 471 to swing more smoothly from side to side.

[0042] The swing mechanism 6 includes two sliding seats 61, a swing rod 62, several first abutting blocks 63 and several second abutting blocks 64. Both ends of the swing rod 62 are provided with arc surfaces 621. The first abutting blocks 63 and the second abutting blocks 64 are each provided with two symmetrically arranged guide wedge surfaces 65. The two sliding seats 61 are symmetrically arranged on the outer wall of the rotating drum 45. The swing rod 62 is slidably arranged on the two sliding seats 61. The nozzle assembly 47 is fixedly connected to the swing rod 62. All the first abutting blocks 63 are arranged at equal angles along the circumference of the rotating drum 45 on the inner side wall of one of the lower support frames 43. All the second abutting blocks 64 are arranged at equal angles along the circumference of the rotating drum 45 on the inner wall of the other lower support frame 43. The second abutting blocks 64 are located between two adjacent first abutting blocks 63.

[0043] The push rod 51 drives the push rack 52 to move back and forth cyclically. The push rack 52 drives the driven gear 53 to rotate clockwise and counterclockwise. The driven gear 53 drives the rotating shaft 46 and the rotating drum 45 to rotate synchronously. The rotating drum 45 drives all the nozzle assemblies 47 to rotate synchronously. While rotating, the rotating drum 45 also drives the swing rod 62 to rotate synchronously. When the swing rod 62 rotates, the arc surface 621 of one end of the swing rod 62 abuts against the guide wedge surface 65 on one side of the first abutment block 63. The arc surface 621 and the guide wedge surface 65 cooperate to make the other end of the swing rod 62 move towards the inner wall of the other lower support 43. Then the first abutment block 63 disengages from one end of the swing rod 62. At this time, the other end of the swing rod 62... It just so happens to come into contact with one side of the guide wedge surface 65 of the second abutment block 64. Then, the guide wedge surface 65 cooperates with the arc surface 621 of the other end of the swing rod 62 to drive one end of the swing rod 62 to move towards the inner wall of the downward support frame 43. Since the first abutment block 63 and the second abutment block 64 are provided with two symmetrically arranged guide wedge surfaces 65, the arc surface 621 can come into contact with one side of the guide wedge surface 65 no matter whether the swing rod 62 rotates clockwise or counterclockwise with the rotating cylinder 45. This allows the swing rod 62 to swing continuously left and right, that is, the air jet head 471 can swing continuously left and right, thereby expanding the effective range of the air jet head 471 and the release agent can be evenly sprayed on the mold.

[0044] Of course, before spraying the release agent, gas can be introduced into the jet nozzle 471 through the tee connector 433 and the connecting pipe 432. This allows the jet nozzle 471 to spray gas to blow air onto the mold, so that dust will not stick to the mold.

[0045] When the cover plate 42 moves down, it also drives the suction mechanism 7 to work. The suction mechanism 7 includes an air tank 71, a synchronizing rod 72, and a driving component 73 for driving the synchronizing rod 72 to move left and right. A movable plug 711 is slidably provided inside the air tank 71, which divides the interior of the air tank 71 into two air chambers 712. A discharge pipe 713 is connected to the bottom of the middle end of the air tank 71. A collection cylinder 714 is detachably provided on the discharge pipe 713. Two ventilation pipes 715 are provided on the outer wall of the air tank 71, which are respectively connected to the two air chambers 712. Solenoid valves are provided on both the ventilation pipes 715 and the discharge pipe 713. The air tank 71 is fixedly connected to the bottom of the base 1. The synchronizing rod 72 is slidably provided on the air tank 71, and the synchronizing rod 72 is coaxial with the air tank 71. One end of the two ventilation pipes 715 is respectively connected to the two die-casting chambers 21. The driving component 73 is provided at the bottom of the base 1 and is connected to the two cover plates 42 in a transmission manner.

[0046] The drive assembly 73 includes a U-shaped rod 731, two guide seats 732, two L-shaped guide rods 733, and two transmission components 734. The U-shaped rod 731 is fixedly connected to both ends of the synchronizing rod 72. The two guide seats 732 are respectively disposed on the outer walls of both sides of the support frame 2. The two L-shaped guide rods 733 are slidably disposed on the two guide seats 732. One end of the two L-shaped guide rods 733 is fixedly connected to the top of the two cover plates 42. The two transmission components 734 are symmetrically disposed at the bottom of the base 1. Both transmission components 734 are connected to the U-shaped rod 731. The two L-shaped guide rods 733 are selectively connected to the two transmission components 734.

[0047] The transmission component 734 includes an L-shaped mounting base 7341, on which a first synchronous shaft 7342 and a second synchronous shaft 7343 are rotatably mounted. The two ends of the first synchronous shaft 7342 are respectively provided with a first gear 7344 and a second gear 7345. One end of the second synchronous shaft 7343 is provided with a third gear 7346 that meshes with the second gear 7345. The lower half of the outer wall of the L-shaped guide rod 733 is provided with a plurality of equally spaced first tooth grooves 7331. Both ends of the U-shaped rod 731 are provided with extension rods 7311. The top of the extension rods 7311 is provided with a plurality of equally spaced second tooth grooves 7312. The L-shaped mounting base 7341 is located at the bottom of the base 1. The first gear 7344 meshes with the second tooth grooves 7312, and the third gear 7346 selectively meshes with the first tooth grooves 7331.

[0048] As the cover plate 42 moves downward, it also drives the corresponding L-shaped guide rod 733 downward. This L-shaped guide rod 733 gradually approaches the corresponding third gear 7346. Then, the L-shaped guide rod 733 drives the third gear 7346 to rotate using the first tooth groove 7331. At this time, the other L-shaped guide rod 733 is not meshed with the other third gear 7346. After the third gear 7346 rotates, it drives the second gear 7345 to rotate in the opposite direction. The second gear 7345 drives the first synchronous shaft 7342 to rotate in the opposite direction synchronously. The first synchronous shaft 7342 drives the first gear 7344 to rotate in the opposite direction synchronously. The first gear 7344 drives the corresponding extension through the second tooth groove 7312. The extension rod 7311 moves outward, causing the U-shaped rod 731 to move synchronously. The U-shaped rod 731 then drives the synchronizing rod 72 and the movable plug 711 to move synchronously. Initially, the movable plug 711 is located in the middle of the air tank 71, blocking the inlet of the discharge pipe 713. After the movable plug 711 moves, the inlet of the discharge pipe 713 opens, and the solenoid valve opens the discharge pipe 713. One air chamber 712 shrinks in volume, while the other air chamber 712 increases in volume. The air in the reduced-volume air chamber 712 enters the soon-to-be-closed die-casting chamber 21 through the ventilation pipe 715, thus assisting in the die-casting of the compressor housing. After auxiliary cooling is performed and the spraying operation is completed, the lifting electric push rod 41 drives the cover plate 42 to move upward. The cover plate 42 drives the L-shaped guide rod 733 and the sealing door 31 to move upward synchronously. When the L-shaped guide rod 733 moves upward, the cooperation between the first tooth groove 7331, the second tooth groove 7312, the first gear 7344, the second gear 7345, and the third gear 7346 can drive one end of the synchronizing rod 72 to move into the air tank 71. The movable plug 711 can move towards the middle of the air tank 71 synchronously with the synchronizing rod 72. When the movable plug 711 moves, it generates a pumping force on the small air cavity 712. At this time, the solenoid valve on the discharge pipe 713 works to close the discharge pipe. 713, the pumping force can be transmitted to the corresponding die-casting cavity 21 through the ventilation pipe 715, so that the floating release agent can be sucked into the gas tank 71. In order to improve the adsorption effect of the floating release agent, a hopper-shaped settling tank 11 is provided in the die-casting cavity 21. The ventilation pipe 715 is connected to the settling tank 11. Then the floating agent can come into contact with each other in the gas chamber 712 and gradually become liquid. When the movable plug 711 moves, it generates a squeezing force on another large gas chamber 712. The squeezing force can squeeze the gas in the corresponding gas chamber 712 into another die-casting cavity 21, so as to perform auxiliary cooling operation on the compressor housing being die-cast in the other die-casting cavity 21.

[0049] Next, the worker can smoothly remove the die-cast finished product, put the raw material back in, and then the die-casting cylinder works to complete the die-casting of another compressor housing. This die-casting chamber 21 then performs the die-casting operation. Another lifting electric push rod 41 works to repeat the above operations. The liquid flotation agent located in the air chamber 712 can flow into the collection cylinder 714 through the discharge pipe 713. Of course, when the entire equipment is not in use, the corresponding pipe can be closed by the solenoid valve.
