It is mainly composed of main machine, hydraulic system, molten pool holding furnace, liquid surface pressurization device, electrical control system and mold cooling system. Modern low-pressure casting machine combines computer information technology and automatic control technology, which can accurately simulate the pressurization process of casting and repeatedly reproduce the pressurization curve. Some low-pressure casting machines also have fault self-diagnosis function. This makes the low-pressure casting machine have higher efficiency and stability in the production process.

[0003] The low-pressure casting machine also needs to be jacked up for maintenance during use, especially for the molds on the low-pressure casting machine. Only by regularly maintaining the molds can the quality of the processed products be guaranteed.

[0004] With respect to the existing related technologies, it is believed that the following defects exist: when oiling and maintaining the mold on the low-pressure casting machine, manual oiling is mostly adopted. This method has certain risks and requires the staff to be in the low-pressure casting machine. At the same time, the gaps in the mold may be leaked due to the staff's carelessness, and the work efficiency is low. Therefore, in view of the above problems, a low-pressure casting machine that is easy to maintain is proposed. Utility Model Content

[0012] The utility model is beneficial in that:

[0013] 1. The utility model starts the servo motor to reverse, so that the servo motor moves again through the screw rod with the movable block and the connecting plate toward the mold direction of the low-pressure casting machine body, and uses the brush to oil the surface of the mold for maintenance. Since the mold surface is not completely flat and has depressions, the visual sensor on the connecting plate will send a signal to the signal controller, and the signal controller will start the electric push rod in the movable block, so that the electric push rod moves with the connecting plate and the brush toward the depression of the mold, and then the gap of the mold is oiled for maintenance, achieving more comprehensive and efficient coating and maintenance, greatly improving work efficiency while avoiding the staff from being in the low-pressure casting machine body, greatly protecting the staff.

[0026] Specifically, a groove is provided on one side of the low-pressure casting machine body 1, a multi-stage telescopic rod 11 is fixedly installed on the bottom of the connecting plate 5, the multi-stage telescopic rod 11 is composed of a plurality of slidingly connected rods, the bottom of the multi-stage telescopic rod 11 is slidably connected to the groove, an electric push rod 8 is fixedly installed inside the movable block 4, the output end of the electric push rod 8 is fixedly connected to the connecting plate 5, a visual sensor 9 is fixedly installed on one side of the connecting plate 5, and a signal controller 10 is fixedly installed on one side of the movable block 4.

[0027] During operation, when the mold in the low-pressure casting machine body 1 needs to be oiled and maintained, the servo motor 2 on one side of the low-pressure casting machine body 1 is started, and the servo motor 2 moves toward the oil storage box 7 through the screw rod 3 with the movable block 4, the connecting plate 5 and the brush 6, and then the brush 6 is immersed and moistened in the oil storage box 7. This is the initial state. When the connecting plate 5 moves, the multi-stage telescopic rod 11 in the groove will provide support for the connecting plate 5, thereby preventing the connecting plate 5 from tilting and allowing it to slide normally. When the brush 6 is completely soaked, the servo motor 2 is started again to reverse, so that the servo motor 2 moves again through the screw rod 3 with the movable block 4 and the connecting plate 5 toward the mold direction of the low-pressure casting machine body 1, and the brush 6 is used to apply oil to the surface of the mold for maintenance. Since the mold surface is not completely flat and has a depression, the visual sensor 9 on the connecting plate 5 will send a signal to the signal controller 10, and the signal controller 10 is used to start the electric push rod 8 in the movable block 4, so that the electric push rod 8 moves with the connecting plate 5 and the brush 6 to the depression of the mold, and then the gap of the mold is oiled for maintenance, so as to achieve more comprehensive and efficient coating and maintenance, which greatly improves the work efficiency and avoids the staff from being in the low-pressure casting machine body 1, thus greatly protecting the staff. When the oiling maintenance work is completed, the servo motor 2 will drive the connecting plate 5 and the brush 6 to move, so that the brush 6 is reset to the oil storage box 7 for the next use.

[0028] Two fixed blocks 12 are fixedly installed on one side of the low-pressure casting machine body 1, and a slide groove 13 running through the fixed block 12 is opened on one side of the fixed block 12. A cover plate 14 is slidably connected inside the slide groove 13. The cover plate 14 is located above the oil storage box 7. A spring 15 is fixedly installed inside the slide groove 13, and one end of the spring 15 is fixedly connected to the cover plate 14.

[0029] During operation, when the connecting plate 5 leaves the oil storage box 7, the cover plate 14 slides toward the oil storage box 7 under the action of the spring 15, and then covers the oil storage box 7, thereby protecting the lubricating oil in the oil storage box 7 and reducing the pollution of the lubricating oil. When the connecting plate 5 slides toward the oil storage box 7, the connecting plate 5 will push open the cover plate 14, thereby facilitating the entry of the brush 6.

[0030] An arc-shaped impact plate 16 is fixedly installed on one side of the oil storage box 7, and a plurality of arc-shaped auxiliary plates 17 are fixedly installed on one side of the impact plate 16. A storage box 18 is attached to the low-pressure casting machine body 1 by screws, and the top of the storage box 18 is in contact with the bottom of the oil storage box 7. The bottom of the impact plate 16 is provided with a plurality of through grooves 19 connected to the storage grooves.

[0031] During operation, when the connecting plate 5 is reset with the brush 6, there will be residual lubricating oil in the gap of the brush 6. Since there will be impurities after the brush 6 contacts the mold, the brush 6 will first contact and collide with the impact plate 16 and the auxiliary plate 17 when it is reset into the oil storage box 7, so as to be deformed, thereby shaking off the residual lubricating oil and impurities in the brush 6, causing them to fall onto the impact plate 16 and flow to the storage box 18 through the through groove 19, and be collected and reused by the storage box 18. At the same time, the storage box 18 can also play a role in assisting in lifting the oil storage box 7, so that the oil storage box 7 is placed more stably.

[0032] Working principle: when the mold in the low-pressure casting machine body 1 needs to be oiled and maintained, the servo motor 2 on one side of the low-pressure casting machine body 1 is started, and the servo motor 2 moves toward the oil storage box 7 through the screw rod 3 with the movable block 4, the connecting plate 5 and the brush 6, and then the brush 6 is immersed and moistened in the oil storage box 7. This is the initial state. When the connecting plate 5 moves, the multi-stage telescopic rod 11 in the groove will provide support for the connecting plate 5, thereby preventing the connecting plate 5 from tilting and allowing it to slide normally. When the brush 6 is completely soaked, the servo motor 2 is started again to reverse, so that the servo motor 2 moves again through the screw rod 3 with the movable block 4 and the connecting plate 5 toward the mold direction of the low-pressure casting machine body 1, and the brush 6 is used to apply oil to the surface of the mold for maintenance. Since the mold surface is not completely flat and has a depression, the visual sensor 9 on the connecting plate 5 will send a signal to the signal controller 10, and the signal controller 10 is used to start the electric push rod 8 in the movable block 4, so that the electric push rod 8 moves with the connecting plate 5 and the brush 6 to the depression of the mold, and then the gap of the mold is oiled for maintenance, so as to achieve more comprehensive and efficient coating and maintenance, which greatly improves the work efficiency and avoids the staff from being in the low-pressure casting machine body 1, thus greatly protecting the staff. When the oiling maintenance work is completed, the servo motor 2 will drive the connecting plate 5 and the brush 6 to move, so that the brush 6 is reset to the oil storage box 7 for the next use.

[0033] When the connecting plate 5 leaves the oil storage box 7, the cover plate 14 slides toward the oil storage box 7 under the action of the spring 15, and then covers the oil storage box 7, thereby protecting the lubricating oil in the oil storage box 7 and reducing the pollution of the lubricating oil. When the connecting plate 5 slides toward the oil storage box 7, the connecting plate 5 will push open the cover plate 14, thereby facilitating the entry of the brush 6.

[0034] When the connecting plate 5 is reset with the brush 6, there will be residual lubricating oil in the gap of the brush 6. Since there will be impurities after the brush 6 contacts the mold, the brush 6 will first contact and collide with the impact plate 16 and the auxiliary plate 17 to produce deformation when it is reset into the oil storage box 7, thereby shaking off the residual lubricating oil and impurities in the brush 6, making them fall onto the impact plate 16 and flow to the storage box 18 through the through groove 19, and be collected and reused by the storage box 18. At the same time, the storage box 18 can also play a role in assisting in lifting the oil storage box 7, so that the oil storage box 7 is placed more stably.
