Description

Technical Field

[0001] The present invention relates to the technical field of die-casting machines, in particular to a die-casting machine for new energy automobile parts. Background Art

[0002] The die-casting machine for new energy vehicle parts is a large-scale casting equipment specially used for manufacturing new energy vehicle parts. It usually has a fixed mold and a movable mold. The two molds are combined to form a closed mold cavity. Then the molten metal liquid is poured into the feed barrel of the die-casting machine. The injection piston pushes the metal liquid into the mold cavity at high speed to die-cast the casting. After the die-casting of the casting is completed, the two molds need to be separated and the casting taken out of the cavity.

[0003] In the process of die-casting new energy vehicle battery packs, since die-casting needs to be carried out under high temperature, high pressure and high speed, a large amount of waste gas will be generated. These waste gases mainly come from the volatile gases generated during the heating of the mold, the injection of molten metal and the cooling process. When the two molds are separated, these waste gases will drift directly to the outside. Die-casting waste gas contains a large amount of harmful substances, such as smoke, sulfur dioxide, nitrogen oxides, hydrocarbons, etc., which will cause health hazards to operators working in the new energy vehicle die-casting workshop. At the same time, the waste gas may form a certain amount of smoke or aerosol during the drifting process, especially in the case of poor ventilation. These fumes will accumulate in a certain area. If the operator observes the operating status of the mold, the die-cast new energy vehicle battery pack or the die-casting machine, the smoke formed by the exhaust gas will block the operator's line of sight, making it difficult for the operator to clearly see the die-casting of key parts.

[0004] In addition, some particulate matter, oil mist and some volatile substances in the exhaust gas will adhere to the surface of surrounding machinery during the emission and diffusion process. Since the adhesion of particulate matter and oil mist in the exhaust gas will lead to a decline in mechanical performance and an increase in failures, the maintenance frequency of equipment needs to be increased, including cleaning the machine surface, replacing filters, repairing damaged parts and other maintenance work.

[0005] To this end, a die-casting machine for new energy automobile parts is proposed. Summary of the invention

[0023] Wherein: the surface of the fixed mold 13 close to the movable mold 16 is set as the die casting surface.

[0024] A suction assembly is arranged above the base 11, and the suction assembly is used to extract the die-casting waste gas generated when the fixed mold 13 and the movable mold 16 are separated, and to cool the condensed gas ejected from the die-casting surfaces of the fixed mold 13 and the movable mold 16. The suction assembly includes a bellows 21, and the bellows 21 is fixedly connected to the top surface of the movable mold 16. A bracket 22 is arranged on the top of the inner wall of the bellows 21, and the bracket 22 is rotatably connected to a fan 23. Two short frames 24 arranged on the top surface of the movable mold 16 are symmetrically fixedly connected on both sides of the bellows 21, and an air duct 25 is fixedly connected to each of the two short frames 24. The air duct 25 is connected to the side of the bellows 21 close to the bellows 21. The inside of the bellows 21 is connected, and one end of the two air ducts 25 away from the bellows 21 is facing the die-casting surface of the movable mold 16. Two long frames 26 are fixedly connected to the top surface of the fixed mold 13, and an air duct 27 is fixedly connected to the two long frames 26. The air duct 27 is a U-shaped structure, and the two ends of the air duct 27 are opening structures on the side close to the movable mold 16. The two openings of the air duct 27 are facing the die-casting surface of the fixed mold 13. The air duct 27 and the two air ducts 25 are in a mutually staggered structure. Its function is to prevent the air duct 27 from colliding with the two air ducts 25 when the fixed mold 13 and the movable mold 16 are closed.

[0025] A bellows 28 is fixedly connected between the bellows 21 and the middle of the air duct 27, and an elastic rope 29 is fixedly connected between the two ends of the bellows 28. A cover plate 210 is slidably connected to the top surface of the bellows 21, and a square tube 211 is fixedly connected to the outer wall of the bellows 21. The square tube 211 is slidably connected to the cover plate 210. A spring 212 is sleeved on the outer side of the square tube 211. The two ends of the spring 212 are respectively fixedly connected to the outer wall of the bellows 21 and the cover plate 210. A side box 213 is fixedly connected to the outer wall of the bellows 21 away from the square tube 211. The inner wall of the end of the side box 213 away from the bellows 21 is rotatably connected to the inner wall A pulley 214 is connected, and a belt 215 is connected between the pulley 214 and the fan 23. The top end of the pulley 214 passes through the side box 213, and the end of the pulley 214 passing through the side box 213 is fixedly connected to a gear 216. A rack 1 217 is fixedly connected to the top surface of the fixed wall 12, and the rack 1 217 and the gear 216 are meshed with each other. The end of the rack 1 217 away from the fixed wall 12 is fixedly connected to a connecting plate 218, and the side of the connecting plate 218 close to the fixed mold 13 is fixedly connected to a rack 219, and the end of the rack 219 away from the connecting plate 218 is fixedly connected to one of the long frames 26.

[0026] The teeth on the second rack 219 are oriented in the opposite direction to those on the first rack 217 and are symmetrically arranged on the other side of the connecting plate 218. When the gear 216 contacts the second rack 219, the gear 216 and the second rack 219 can also mesh with each other.

[0027] Specifically: when the gear 216 engages with the rack 219 and moves toward the fixed wall 12, the fan 23 is driven to inhale air toward the bottom; when the gear 216 engages with the rack 1 217 and moves toward the fixed wall 12, the fan 23 is driven to blow air toward the bottom. The connecting plate 218 is configured to be an inverted "U" shape, and the inner walls of the connecting plate 218 are used to allow the gear 216 to pass through, and the connecting plate 218 will not conflict with the gear 216 during this process. The top of the connecting plate 218 away from the rack 217 is fixedly connected to a support rod 220, and the end of the support rod 220 away from the connecting plate 218 extends to the top of the side box 213. The cover plate 210 is fixedly connected to a support frame 221 on the side close to the gear 216. The top of the support frame 221 is configured to be arc-shaped and extends to one side of the side box 213. The support rod 220 is located on the moving path of the support frame 221. The top of the support frame 221 is fixedly connected to a trigger switch 222 at the part that contacts the support rod 220 when moving. The middle part of the support frame 221 is fixedly connected to a semiconductor cooling plate 223 facing the gear 216, and there is an electrical connection between the trigger switch 222 and the semiconductor cooling plate 223.

[0028] Specifically: the trigger switch 222 is triggered to start the semiconductor refrigeration plate 223. When the trigger switch 222 contacts the support rod 220, the semiconductor refrigeration plate 223 is powered on for cooling. The cover plate 210 is fixedly connected with an exhaust duct 224, which extends to the space between the fixed wall 13 and the movable mold 16. The top of the inner wall of the bellows 21 is fixedly connected with a sealing plate 225. When the support frame 221 is not in contact with the support rod 220, the cover plate 210 will move toward the side box 213 under the action of the spring 213. At this time, the exhaust duct 224 and the sealing plate 225 are staggered. When the support frame 221 contacts the support rod 220, the support frame 221 is squeezed by the support rod 220 to drive the cover plate 210 to move toward the square tube 211. When the cover plate 210 moves to the farthest distance on one side of the square tube 211, the exhaust duct 224 is blocked by the sealing plate 225.

[0029] Among them: Reference Figure 8 As shown, the support rod 220 is only located on one side of the connecting plate 218 close to the rack 1 217, that is, when the trigger switch 222 moves to the rack 2 219 position, the trigger switch 222 does not conflict with the support rod 220, and the semiconductor cooling plate 223 is powered off and no longer cools.

[0030] Among them, the elastic rope 29 is set to prevent the movable mold 16 and the fixed mold 13 from fitting together during the die-casting process. The bellows 28 falls down to block the fitting of the movable mold 16 and the fixed mold 13. When the movable mold 16 and the fixed mold 13 are separated, the bellows 28 and the elastic rope 29 are both in a stretched and tightened state. When the movable mold 16 and the fixed mold 13 are closed, the elastic rope 29 elastically contracts and drives the bellows 28 to return to a horizontal state.

[0031] When the support frame 221 conflicts with the support rod 220 , one end of the exhaust pipe 224 connected to the cover plate 210 overlaps with the sealing plate 225 , that is, the interior of the bellows 21 is not connected to the exhaust pipe 224 .

[0032] Among them, one end of the exhaust pipe 224 away from the cover plate 210 is connected to an external exhaust gas collecting device, and the exhaust gas collecting device has suction force, that is, exhaust gas can be sucked into the inside of the bellows 21 through the exhaust pipe 224.

[0033] Among them: when die-casting the new energy vehicle battery pack, the telescopic end of the hydraulic rod 15 extends, so that the movable mold 16 fits the die-casting surface of the fixed mold 13, and molten metal is injected into the mold cavity formed between the two, and the new energy vehicle battery pack is die-cast.

[0034] When the suction assembly is in use, the die-casting surfaces of the fixed mold 13 and the movable mold 16 are in contact, the telescopic end of the hydraulic rod 15 is extended, and the die-casting work of the new energy vehicle battery pack has just been completed. When the fixed mold 13 and the movable mold 16 are ready to separate, the gear 216 is meshed with the end of the rack 219 away from the connecting plate 218, and the cover plate 210 completely covers the middle part of the top surface of the bellows 21, and the sealing plate 225 and the exhaust pipe 224 are staggered at the part where the cover plate 210 is connected, and they are not blocked, as follows: At this time, the telescopic end of the hydraulic rod 15 contracts, and while the telescopic end of the hydraulic rod 15 contracts, it drives the movable mold 16 to move toward the fixed wall 12. At this time, the movable mold 16 slides on the multiple guide columns 14, and the movable mold 16 is separated from the die-casting surface of the fixed mold 13. At this time, the die-casting exhaust gas generated in the die-casting process of the new energy vehicle battery pack overflows to the outside. In the process of the movable mold 16 moving toward the fixed wall 12, the gear 216 engages the rack 219 and moves synchronously toward the fixed wall 12. At this time, the gear 216 engages the rack 219 to rotate, and while the gear 216 rotates, it drives the pulley 214 to rotate synchronously. While the pulley 214 rotates, it drives the fan 23 to rotate synchronously through the belt 215. At this time, the rotation of the fan 23 sucks air toward the bottom, and the suction force Air is sucked toward the die-casting surface of the movable mold 16 through the air duct 1 25 on both sides of the bellows 21, and at the same time, the suction force is transmitted to the air duct 2 27 located at the top of the fixed mold 13 through the bellows 28, so that the air duct 2 27 sucks air toward the die-casting surface of the fixed mold 13. It should be noted that in the process of the movable mold 16 moving away from the fixed mold 13, the bellows 28 stretches and elastically stretches the elastic rope 29. At this time, the die-casting exhaust gas is guided and collected into the inside of the bellows 21 by the suction force of the air duct 1 25 and the air duct 2 27. Since the fan 23 sucks air toward the bottom and exhausts air toward the top at this time, the die-casting exhaust gas located inside the bellows 21 is collected into the external exhaust gas collection device through the exhaust duct 224 by the upward exhaust action of the fan 23 and the suction action of the external exhaust gas collection device.

[0035] At this time, the exhaust gas generated by the die-cast new energy vehicle battery pack generated by the separation of the dynamic mold 16 and the die-casting surface of the fixed mold 13 is sucked away and collected, which can prevent the exhaust gas from being inhaled by the surrounding staff, improve the air quality of the working environment, reduce respiratory irritation and allergic reactions, and at the same time avoid the accumulation of exhaust gas from the die-cast new energy vehicle battery pack, ensure that the smoke formed by the exhaust gas does not block the staff's line of sight, and ensure that the staff can intuitively observe the operating status of the mold, the die-cast new energy vehicle battery pack or the die-casting machine.

[0036] At the same time, the exhaust gas of the die-cast new energy vehicle battery pack generated by the separation of the die-casting surface of the movable mold 16 and the fixed mold 13 is sucked away and collected, thereby preventing the particles and oil mist in the exhaust gas of the die-cast new energy vehicle battery pack from adhering to the surface of the surrounding machinery, ensuring the mechanical properties of the surrounding equipment, and reducing the time and labor costs required for maintenance work such as cleaning the machine surface and repairing damaged parts.

[0037] When the gear 216 moves to the connecting plate 218, the gear 216 stops rotating. Then, as the movable mold 16 continues to move, the gear 216 meshes with the rack 217, and then the gear 216 rotates in the opposite direction, driving the fan 23 to rotate in the opposite direction, so that the fan 23 blows air to the bottom. At the same time, the top arc surface of the support frame 221 contacts the support rod 220, and the trigger switch 222 contacts the support rod 220, so that the cover plate 210 is squeezed by the support rod 220 through the support frame 221 and pushed in the direction away from the gear 216. At this time, the cover plate 210 slides on the square tube 211, and the spring 212 is elastically stretched. At this time, the movement of the bellows 21 causes a gap to appear on the top surface of the bellows 21, and the internal space of the bellows 21 is connected to the external environment through the gap. As the cover plate 210 moves, the semiconductor The semiconductor cooling sheet 223 is located directly above the gap. At the same time, the trigger switch 222 contacts the support rod 220, so that the semiconductor cooling sheet 223 starts working, and the fan 23 works to cool, so that the surrounding air temperature drops. At this time, the fan 23 exhausts air to the bottom, that is, inhales air from the top. The fan 23 sucks cold air into the cavity in the gap exposed by the bellows 21, and sprays it to the die-casting surfaces of the fixed mold 13 and the movable mold 16 through the air duct 1 25 and the air duct 2 27. The sprayed cold air dissipates heat and cools the die-casting surfaces of the fixed mold 13 and the movable mold 16, as well as the die-cast new energy vehicle battery pack, reducing thermal fatigue and wear of the die-casting surfaces of the fixed mold 13 and the movable mold 16 at high temperatures. High temperature will reduce the hardness and strength of the mold and make it easy to deform. Cold air cooling can keep the mold within a suitable temperature range to avoid deformation caused by overheating.

[0038] At the same time, cold air is sprayed toward the die-casting surfaces of the fixed mold 13 and the movable mold 16 and the die-cast new energy vehicle battery pack through the air duct 1 25 and the air duct 2 27. The efficient cooling of the cold air can greatly shorten the cooling time of the die-cast new energy vehicle battery pack. Compared with natural cooling or traditional cooling methods, the cold air can reduce the temperature of the die-cast new energy vehicle battery pack more quickly, so that the die-cast new energy vehicle battery pack can reach the demolding temperature faster. At the same time, due to the accelerated cooling speed, the mold can perform the next die-casting cycle faster, which improves the use efficiency of the mold and increases the output per unit time.

[0039] When the cover plate 210 moves, the exhaust pipe 224 is also driven to move synchronously, so that the exhaust pipe 224 is connected to the cover plate 210 and overlaps with the sealing plate 225. At this time, the interior of the cover plate 210 is no longer connected to the interior of the exhaust pipe 224, and the die-casting waste gas previously sucked into the exhaust pipe 224 will not enter the bellows 21 cavity again.

[0040] The above-mentioned inhalation of die-casting exhaust gas and ejection of cold air are carried out alternately during the separation process of the fixed mold 13 and the movable mold 16. The initial power source comes from the separation of the fixed mold 13 and the movable mold 16, which can realize the immediate suction of exhaust gas after the mold separation, thereby avoiding the accumulation of exhaust gas generated by the die-casting new energy vehicle battery pack in the working area, and reducing the interference time of the exhaust gas generated by the die-casting new energy vehicle battery pack on subsequent operations. Subsequently, cold air is ejected to accelerate the cooling of the die-cast new energy vehicle battery pack, so that the die-cast new energy vehicle battery pack can reach the demolding temperature faster, thereby shortening the entire production cycle. At the same time, the process of inhaling exhaust gas and ejecting cold air is carried out synchronously with the mold separation, which makes full use of the power and time during the mold separation, making the entire production process more compact and efficient.

[0041] It should be noted that the attached drawings are only for the display of its structure, and the proportions of its components are not absolutely accurate, such as the size of the gear 216, the number of teeth of the rack 1 218 and the rack 2 219, the gear ratio of the gear 216 and the two racks, etc. The die-casting machine in actual production is usually a large-scale mechanism with a length and width of about five meters, the diameter of the air duct 1 25 and the air duct 2 27 is about 30-50 centimeters, and the stroke between the movable mold 16 and the fixed mold 13 is about two meters. The amount of exhaust gas generated when the movable mold 16 and the fixed mold 13 are opened is small, and the density of the exhaust gas is also very small. When the exhaust gas is discharged, the exhaust gas will drift upward as a whole. The gear 216 and the rack set according to the above-mentioned stroke length drive the fan 23, which can fully achieve the various technical effects described in the specification, especially the process of guiding the exhaust gas through the fan 23 and blowing and cooling the die-cast new energy vehicle battery pack. Example

[0042] See also Fig.10 and Fig.11As shown, a dehumidification component is provided on the bellows 21, and the dehumidification component is used to prevent the condensed water of the semiconductor refrigeration sheet 223 from dripping into the inside of the bellows 21 during the condensation process. The dehumidification component includes a back plate 31, and the back plate 31 is fixedly connected to the middle part of the support frame 221, and a sponge 32 is fixedly connected to the side of the bottom end of the support frame 221 close to the semiconductor refrigeration sheet 223, and the sponge 32 is located at the bottom of the semiconductor refrigeration sheet 223, and the sponge 32 fits the bottom of the semiconductor refrigeration sheet 223. The top surface of the side box 213 is fixedly connected to a water tank 33, and a plurality of leakage holes 34 are provided on the top surface of the water tank 33. A pressure plate 35 is fixedly connected to the top surface of the water tank 33, and a drain pipe 36 is fixedly connected to the bottom surface of the water tank 33 close to the fixed wall 12. A fixed frame 37 is fixedly connected to the side of the movable mold 16 close to the fixed wall 12, and the fixed frame 37 is fixedly connected to the drain pipe 36, and a drain cover 38 is clamped on the bottom end of the drain pipe 36.

[0043] There is a gap between the lower surface of the inner wall of the pressing plate 35 and the upper surface of the outer wall of the water tank 33 . The gap is located on the moving path of the sponge 32 , and the gap is smaller than the thickness of the sponge 32 .

[0044] The bottom of the inner wall of the water tank 33 is arranged as an inclined surface, and the bottom end of the inclined surface is inclined toward the side of the drain pipe 36 .

[0045] Among them: the staff can pull out the drain cover 38 to release the condensed water inside the drain pipe 36.

[0046] When the dehumidification component is in use, the movable mold 16 is moving toward the fixed mold 13, and is in the process of needing to close the mold for die-casting the new energy vehicle battery pack, that is, the gear 216 is meshed with the rack 1 217 at this time, and the gear 216 is about to mesh with the rack 2 219.

[0047] At this time, as the semiconductor refrigeration sheet 223 operates, condensed water will condense on its surface. Since the sponge 32 fits the bottom of the semiconductor refrigeration sheet 223, the condensed water at the bottom of the semiconductor refrigeration sheet 223 is absorbed by the sponge 32, and the condensed water on the side of the semiconductor refrigeration sheet 223 also drips onto the sponge 32. When the movable mold 16 moves to the gear 216 engaging the rack 1 217, the support frame 221 no longer conflicts with the support rod 220. Under the action of the elastic contraction of the spring 212, the cover plate 210 is pulled to move toward the gear 216. At this time, the cover plate 210 drives the support frame 221 to move synchronously toward the pressure plate 35. When the support frame 221 moves, the support frame 221 drives the sponge 32 and the semiconductor refrigeration sheet 223 to move synchronously. The sponge 32 moves synchronously, and the upper surface of the pressing plate 35 contacts the part where the sponge 32 contacts the semiconductor refrigeration plate 223. Since the sponge 32 is soft and deformable, as the support frame 221 moves, the pressing plate 35 extends into between the sponge 32 and the semiconductor refrigeration plate 223 to separate the two. At the same time, the sponge 32 enters the gap between the pressing plate 35 and the water tank 33, so that the sponge 32 is squeezed by the pressing plate 35 and the water tank 33, and the condensed water inside the sponge 32 is squeezed out and enters the water tank 33 through the leakage hole 34 until the sponge 32 contacts the pressing plate 35. At this time, the condensed water entering the water tank 33 flows along the bottom slope of the water tank 33 and enters the drain pipe 36.

[0048] At this time, the condensed water inside the sponge 32 is cleared. When the subsequent die-casting is completed, the fixed mold 13 is separated from the movable mold 16 and the above-mentioned suction component is in the process of spraying cold air. At this time, the sponge 32 that absorbs the condensed water at the bottom of the semiconductor refrigeration plate 223 is in a dry state, which can prevent excessive moisture inside the sponge 32 from dripping into the inside of the bellows 21.

[0049] In the above process, the condensed water inside the sponge 32 is squeezed out through the water tank 33 and the pressure plate 35 to ensure that during the operation of the semiconductor refrigeration plate 223, the sponge 32 can absorb the condensed water on the semiconductor refrigeration plate 223, and prevent the condensed water from dripping into the inside of the bellows 21, and prevent it from mixing with the cold air and spraying onto the surface of the mold and the die-cast new energy vehicle battery pack, ensuring that the mold and the die-cast new energy vehicle battery pack will not cause severe thermal shock due to the spraying of condensed water, thereby ensuring the mechanical properties and service life of the mold and the die-cast new energy vehicle battery pack.
