Description

Technical Field

[0001] This utility model relates to the technical field of rust prevention components for magnesium alloy die castings, specifically a lubrication device for rust prevention of magnesium alloy die castings. Background Technology

[0002] Rust prevention of magnesium alloy die castings is an important production process. It typically involves applying lubricating oil to the die castings using methods such as immersion, spraying, or brushing. The lubricating oil forms a continuous film on the surface of the die casting, isolating the metal surface from corrosive media such as air and moisture. This prevents oxygen and water from contacting the magnesium alloy, slowing down oxidation and corrosion. A good lubrication device can improve the efficiency of lubricating oil application for magnesium alloy die castings, effectively aiding in rust prevention.

[0003] In general, lubrication devices on the market use lubricating oil spray guns for lubrication spraying. However, this type of tool has a limited spraying range due to its single-hole nozzle. When the size of the magnesium alloy die-casting workpiece is large, it is necessary to spray the workpiece repeatedly, which is labor-intensive and has poor applicability, causing trouble for users. Therefore, we propose a lubrication device for rust prevention of magnesium alloy die-castings. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a lubrication device for rust prevention of magnesium alloy die-casting parts, including an oil box 1, a lower oil box 4, and a right oil drain pipe 6. A pressure pump 2 for applying pressure is connected to one side of the oil box 1. An oil tank 3 for storing lubricating oil is threadedly connected to the top of the upper end of the oil box 1. The lower oil box 4 is slidably connected to the bottom of the inner wall of the oil box 1. A left oil drain pipe 5 is provided along one side of the lower oil box 4. A right oil drain pipe 6 is connected to the side of the oil box 1 away from the left oil drain pipe 5. A control valve 7 is connected to the end of the right oil drain pipe 6. A connector 71 is provided at the connection between the control valve 7 and the right oil drain pipe 6, and the connector 71 and the right oil drain pipe 6 are connected by a clamp. A metal hose 72 is connected to the lower end of the control valve 7. Furthermore, the end of the metal hose 72 furthest from the control valve 7 is connected to a showerhead 73. The right oil drain pipe 6, control valve 7, connector 71, metal hose 72, and showerhead 73 constitute a lubricating oil spraying structure. The lubricating oil is sprayed over a wide area onto the magnesium alloy die-casting through the perforated showerhead 73 to meet the needs of rust prevention and lubrication protection for the surface and interior of the magnesium alloy die-casting. At the same time, the lubricating oil spraying structure uses the metal hose 72 as a connecting pipe. The metal hose 72 has a certain degree of flexibility and deformability in both the axial and radial directions, and can adapt to bending in different directions, so as to meet the working requirements of aiming the showerhead 73 at the surface of the magnesium alloy die-casting for lubricating oil spraying.

[0025] Mounting plates 11 are welded to both sides of the back of the oil box 1, and the oil box 1 is fastened to the magnesium alloy die-casting machine by bolts through the mounting plates 11. The mounting plates 11 are used as mounting components and are fixed by welding. The connection strength is high and the structure is stable, ensuring that the oil box 1 is fixed to the magnesium alloy die-casting machine for a long time to meet the needs of subsequent lubrication spraying of magnesium alloy die-cast parts. A supporting and protective connecting plate 12 is welded to the bottom of the lower end of the oil box 1, and the lower oil box 4 is slidably connected to the upper end of the connecting plate 12. A connecting pipe 13 is connected to the middle of the oil box 1, and the two sides of the middle of the connecting pipe 13 are respectively connected to the pressure pump 2 and the right oil drain pipe 6 through pipes. The connecting pipe 13 serves as an oil distribution pipe and is connected to the pressure pump 2, oil tank 3, lower oil box 4 and right oil drain pipe 6 respectively. By closing the distribution pipe, the working requirements for oil distribution to the left oil drain pipe 5 and the right oil drain pipe 6 are met.

[0026] A toggle block 41 is fixed to the front end of the lower oil box 4. A sealing ring 42 is bonded to the connection between the lower oil box 4 and the connecting plate 12. A recessed groove 43 is formed in the middle of the upper end of the lower oil box 4, and a through hole 44 is formed on one side of the recessed groove 43. The recessed groove 43 is fitted to the bottom of the connecting pipe 13, and the connecting pipe 13 supplies oil to the lower oil box 4 through the through hole 44. The lower oil box 4 serves as a control component for the left oil drain pipe 5. A sealing ring 42 is bonded to the connection between the lower oil box 4 and the connecting plate 12. Through sealing protection, the connection gap between the lower oil box 4 and the connecting plate 12 is reduced, reducing the possibility of oil leakage. At the same time, the range of motion of the lower oil box 4 is controlled by the connecting plate 12 and the toggle block 41. When the user moves the toggle block 41, the thrust... Under the force of the action, the lower oil box 4 moves within a small range within the oil box 1 and the connecting plate 12. The bottom of its connecting pipe 13 moves synchronously within the sinking groove 43. When the bottom of the connecting pipe 13 contacts the through hole 44, it is in the oil supply state. Conversely, when the bottom of the connecting pipe 13 closes with the through hole 44, the connecting pipe 13 stops supplying oil to the lower oil box 4. This structure is simple to operate and convenient to use. This structure serves as the opening and closing structure of the left oil pipe 5 and works in conjunction with the lubricating oil spraying structure to meet the user's needs for different operating methods under different circumstances, providing convenience for the user. The upper end of the oil tank 3 is threadedly connected to a sealing cap 31, and the lower end of the oil tank 3 is connected to a connector 32. The oil tank 3 is threadedly connected to the upper part of the connecting pipe 13 through the connector 32.

[0027] Working principle: For this type of lubrication device used for rust prevention of magnesium alloy die-castings, firstly, suitable lubricating oil is poured into the oil tank 3, and the upper part of the oil tank 3 is sealed by rotating the sealing cap 31. At this time, the user aligns the connector 32 with the connecting pipe 13 on the oil box 1 and makes a threaded connection. At the same time, when the user moves the toggle block 41, the lower oil box 4 moves slightly within the oil box 1 and the connecting plate 12 under the action of the thrust. The bottom of its connecting pipe 13 moves synchronously within the sinkhole 43. When the bottom of the connecting pipe 13 closes with the through hole 44, the connecting pipe... 13 stops supplying oil to the lower oil box 4. Then, the user opens the control valve 7, which connects the right oil drain pipe 6 and the metal hose 72. Under the pressure of the pressure pump 2, the lubricant flows from the connecting pipe 13 into the right oil drain pipe 6, and then sprays out from the metal hose 72 along the multi-hole lotus-shaped nozzle 73. At the same time, when the control valve 7 is closed, the bottom of its connecting pipe 13 is in contact with the through hole 44, which is the oil supply state. The lubricating oil falls into the lower oil box 4 and is discharged from the left oil drain pipe 5. Finally, the user lubricates and prevents rust on the surface of the magnesium alloy die casting by applying the component.
